FY 2009–2010 Water Quality Activity 

TITLE: 

Additional Dry Weather Monitoring 

PROJECT SUMMARY 

The City of La Mesa (City) has been focused on eliminating pollutants from entering our 

receiving water bodies and identifying pollutant sources. Consequently, the City conducted 

additional non-storm water quality monitoring within the San Diego River Watershed. The 

purpose of the study was to evaluate the water quality of the discharged flow. Two 

sampling locations were identified within the Alvarado Drainage Basin. All water samples 

during this study were taken in June 2010 and were evaluated for the same suite of 

constituents measured in the City’s annual Dry Weather Field Screening and Analytical 

Monitoring Program, receiving water body 303 (d) listings constituents, and watershed 

constituent of concerns as reported in the WURMP. This included measuring flow, 

temperature, pH, conductivity, turbidity, nitrate, ammonia, orthophosphate, dissolved 

oxygen, and MBAS in the field and total hardness, dissolved metals, chlorpyrifos, diazinon, 

surfactants, oil and grease, TDS, TSS, total coliform, fecal coliform, and enterococcus 

bacteria in the laboratory. Results have been received and are being analyzed. 

PARTICIPATING JURISDCTIONS 

• City of La Mesa 

WATERSHED PRIORITY POLLUTANTS ADDRESSED 

• Bacteria (high priority) 

• TDS (high priority) 

• Turbidity/TSS 

• Diazinon 

• Metals 

• Total Phosphorous, Dissolved Oxygen, and pH (high priority) 

HOW THIS ACTIVITY RELATES TO THE WATERSHED 

This activity is above and beyond the Dry Weather Field Screening and Analytical 

Monitoring Program. Analyzing samples of non-storm water discharge from two locations 

within the San Diego River Watershed provides insight into water quality leaving the City of 

La Mesa. It also enables the City to conduct potential follow-up investigation of potential 

pollutant sources. Monitoring is intended as a long-term activity; however, sampling 

locations may vary each year. This activity is consistent with WURMP Strategic Goals 2 

through 5. 

ACTIVITIES CONDUCTED DURING 2009-2010 

The following activities were conducted during 2008-2009: 

• Identified two discharge locations to monitor within watershed. 

• Conducted sampling in June 2009 inclusive of field monitoring and laboratory 

analysis. 

• Prepare letter report analyzing data.

TITLE: 

Adopt A Park/Adopt A Block 


The City of La Mesa has encouraged the public to participate in activities that help reduce 

pollutant load. Consequently, the City encourages a group of volunteers as part of the 

Adopt-a-Park and Adopt-a-Block Program. Volunteers are encouraged to routinely pick 

trash from various parks within the watershed or along their block. There are seven parks 

within the San Diego River Watershed that are maintained by the volunteer groups. 

Although specific amount of debris collected is not recorded, the groups’ efforts are 

considered a load reduction from debris entering the storm drain system and receiving 

water body. Volunteers logged over 2,000 service hours of time under these programs 

during this reporting period. 






• DO (high priority) 

• Turbidity 


There are seven parks and numerous residential areas located within the San Diego River 

Watershed. Volunteers assigned to parks or within residential areas, routinely collect trash 

and debris within the watershed. These efforts result in a reduction of debris entering the 

storm water conveyance system and receiving water. Removal of debris constitutes a 

reduction in pollutants that are sources of bacteria, TDS and may reduce turbidity or low 

oxygen concentration in receiving waters due to eutrophication. This activity is considered 

by the City as a long-term watershed activity. 


The following activities were conducted during this reporting period 2009-2010: 

• Group organized to collect trash and debris from parks and neighborhood 

blocks, routinely 

• Trash and debris removed from parks and street blocks, and disposed of 

appropriately.

TITLE: Source Tracking Investigation Phase II 2010 

ID NUMBER: SDR-A4 

ACTIVITY IMPLEMENTATION 

Phase II San Diego River Source Tracking Investigation was conducted within 

the City of San Diego’s jurisdiction in the San Diego River Watershed 

Management Area (WMA). The purpose of this investigation was to monitor for 

fecal bacteria, total dissolved solids (TDS), Total Phosphorus, Nitrogen 

compounds, total suspended solids, total and dissolved metals, and pesticides. 

Samples were collected during two storm events. Cleaning of 13 catch basins 

was performed during dry weather and samples were collected during the 

cleaning efforts. The objective of the study was to understand the implications of 

future total maximum daily loads (TMDLs) for fecal bacteria including Bacteroids, 

total dissolved solids (TDS), phosphorus, and dissolved oxygen (DO). The 

monitoring results provide the basis to assess the land uses and related activities 

which contribute bacteria to the San Diego River WMA. 

Results and Findings 

Wet weather monitoring: 

• The lowest bacteria loads were found at Site 6 at the jurisdictional 

boundary with La Mesa. However, during the second wet weather 

sampling event, the majority of samples collected from this jurisdictional 

boundary were positive for human-specific Bacteroides (an indicator for 

recent human fecal contamination), suggesting the presence of human 

fecal matter in the wet weather flows from upstream of the City. Further 

investigation upstream of this sampling location should be undertaken to 

investigate and confirm the source of this contamination, which may 

include homeless populations living within the river floodway, groundwater 

/ septic systems, sanitary sewer systems, and/or illegal dumping. 

• Site 9 (at the jurisdictional boundary with the City of Santee) had the 

highest loads of dissolved orthophosphate, total Kjeldahl nitrogen (TKN), 

and total nitrogen. 

• Site 2 (at the base of the watershed) had the highest loads of nitrite, total 

phosphorus, total orthophosphate and total dissolved solids (TDS) 

compared with other subdrainages, or sectors. 

Dry weather monitoring: 

• Standard mechanical catchbasin cleaning, as conducted by the City on an 

annual basis, appears to effectively reduce pesticide concentrations in dry 

weather flows. 

• Standard catchbasin cleaning, which involves the removal of large solids 

only, was not found to be effective in the reduction of bacterial 

concentrations. 

• Intensive cleaning, using vacuum and steam cleaning was conducted at 

three catchbasin locations. One of the three locations was shown to have 

Page 1


a decrease in enterococci concentrations. The other two sites did not have 

high enough bacteria concentrations to evaluate any significant decreases 

in indicator bacteria concetrations. 

TMDL APPLICABILITY 

• San Diego Region Beaches and Creeks Bacteria TMDL 

TIME SCHEDULE FOR IMPLEMENTATION 

A Monitoring Plan for Phase II of the San Diego River Source Tracking 

Investigation was completed in FY 2010. Monitoring occurred in FY 2010 and 

reporting will be completed in FY 2011.

HIGH PRIORITY WATER QUALITY PROBLEM(S) ADDRESSED 

• Bacteria 

CONSISTENCY WITH THE COLLECTIVE WATERSHED STRATEGY 

Both the City’s Strategic Plan for Watershed Activity Implementation and the 

Collective Watershed Strategy for the San Diego River WMA identify bacteria as 

a high priority water quality problem in the WMA, and recommend implementing 

load reduction/source abatement activities to address them. Implementation of 

this activity will identify the potential sources or areas that are impacting water 

quality within the San Diego River, and provide specific management and Best 

Management Practices (BMPs) recommendations and implementation strategies 

to reduce bacterial loading from the identified sources. 

EFFECTIVENESS ASSESSMENT 

Effectiveness is not being assessed as this study is neither an implementation 

nor education activity. This study is filling pollutant source data gaps as identified 

above. Future activities implemented in response to the results of the monitoring 

study will be reported as separate activities.

TITLE: 

Canine Corners Harry Griffen Park 


The City of La Mesa has encouraged the public to participate in activities that help reduce 

pollutant load. Consequently, the City encourages a group of volunteers known as the 

Canine Corners to clean up pet waste at Harry Griffen Park. This park is located within the 

San Diego River Watershed. Although the specific amount of pet waste is not recorded, 

the group’s effort is considered a load reduction for pet waste and a potential reduction in 

bacteria entering into the storm drain conveyance system. 






• Dissolved Oxygen (high priority) 


Harry Griffen Park is located within the San Diego River Watershed. A volunteer group 

known as the Canine Corners, collect pet waste routinely from the park and dispose of it 

appropriately. These efforts result in a reduction of pet waste entering the storm water 

conveyance system and receiving water. Pet waste is considered a source that 

contributes to elevated levels of bacteria, reduction in dissolved oxygen and increased 

total dissolved solids. This is considered by the City as a long-term activity. 



• Group organized to routinely remove pet waste. 

• Pet waste removed from park and disposed of appropriately.

TITLE: 

Coastal Cleanup Day Alvarado Channel 

ACTIVITY SUMMARY 

The City of La Mesa supported and participated in the California Coastal Cleanup Day 

conducted on September 19, 2009 in coordination with I Love a Clean San Diego and San 

Diego Coastkeeper. A poster specifying date and time for the clean up was placed on the 

City’s bulletin board. California Coastal Cleanup Day is one of the most successful largescale 

cleanup projects in the Country. This event enlists thousands of volunteers 

throughout the state to clean up over 700 polluted coastal and inner-coastal areas. 

Volunteers met at a designated site in Alvarado Channel to collect debris during this 

reporting period. 

PARTICIPATING JURISDICTIONS 


• Volunteers from other jurisdictions 




• Gross Pollutants/Trash 


The California Coastal Cleanup Day at Alvarado Channel is considered an important 

activity in the San Diego River Watershed because removal of trash and debris ultimately 

improves water quality within the watershed. Trash and debris may result in a number of 

negative impacts that contribute to increased contamination such as elevated numbers of 

bacteria in the water and depletion of dissolved oxygen during the decay/breakdown of 

organic material. The cleanup is an effective means of addressing priority pollutants in the 

watershed such as bacteria and dissolved oxygen. It is conducted on an annual basis and 

encourages the public to be active and aware of the importance of pollution prevention. 

This activity also constitutes a load reduction in pollutants within the watershed. 20 pounds 

of trash and debris were collected by 9 volunteers during this event. Although the weight 

was low, hundreds of small items like cigarette butts were collected. A San Diego River 

Watershed fact sheet was also provided to volunteers at the Alvarado Channel site and the 

City’s Storm Water Program Manager discussed watershed concepts and concerns prior 

to commencement of the cleanup. This activity is conducted on an annual basis and 

considered as a long-term activity to reduce trash and debris in receiving water bodies. 

TASKS IMPLEMENTED DURING 2009-2010 

The following tasks were implemented as part of the Coastal Cleanup Day at Alvarado 

Channel during 2009-2010: 

• Advertising and placing posters for the event on the bulletin board, and in 

other City Facilities. 

• Sponsored the event with $1,000 

• Encouraged the public to participate in the event.

TITLE:Forrester Creek Homeless Encampment Removal Project 


The City’s Public Works Department and the El Cajon Police Department 

coordinated efforts and conducted nine (9) homeless encampment sweeps along 

Forrester Creek within the City’s jurisdiction. After the removal of illegal 

encampments, trash and debris was collected and removed from Forrester 

Creek. 

PARTICIPATING JURISDICTION 

• City of El Cajon 


• Trash (high priority) 


HOW THIS ACTIVITY RELATES TO THE SAN DIEGO RIVER WATERSHED 

The sweeps were conducted during the 2009-10 reporting period and targeted 

homeless camps along Forrester Creek and tributaries. During most of the 

sweeps, the Police encountered transients and their camps and took 

appropriate law enforcement action; Public Works maintenance crews then 

removed the trash and encampment items used for the illegal lodging. The 

encampment removal contributed to the betterment of the San Diego River 

Watershed by removing trash and sources of bacteria pollution. This activity is 

consistent with WURMP Strategic Goal 5 for Bacteria Source Reduction. 

TASKS IMPLEMENTED DURING FY 2009-2010 

The following tasks were conducted as part of the Encampment Removal 

activities during fiscal year 2009- 2010: 

• Removal of trash and debris = 24 Cubic Yards (Cumulative)

TITLE: 

Creek to Bay Cleanup 


The City of La Mesa supported and participated in the Creek to Bay Cleanup conducted on 

April 24, 2010 in coordination with I Love a Clean San Diego. A poster specifying date and 

time for the clean up was placed on the City’s bulletin board. 23 Volunteers from the City 

met along Alvarado Channel in La Mesa from 9am to 12pm to collect trash and debris 

along the channel. 



• Volunteers from other jurisdictions 





The Creek to Bay Cleanup is considered an important activity in the San Diego River 

Watershed because removal of trash and debris ultimately improves water quality within 

the watershed. Trash and debris may result in a number of negative impacts that 

contribute to increased contamination such elevated numbers of bacteria in the water and 

depletion of dissolved oxygen during the decay/breakdown of organic material. The 

cleanup is an effective means of addressing priority pollutants in the watershed such as 

bacteria and dissolved oxygen. It is conducted on an annual basis and encourages the 

public to be active and aware of the importance of pollution prevention. This activity also 

constitutes a load reduction in pollutants within the watershed. A total of 475 pounds of 

trash and debris were collected during this event. A San Diego River Watershed fact sheet 

was provided to volunteers at the cleanup. This activity is considered a long-term activity to 

reduce pollutants from entering receiving water bodies. 

TASKS IMPLEMENTED DURING 2009-2010 

The following tasks were implemented as part of the Creek to Bay Cleanup during 2009- 

2010: 

• Advertised and placed posters for the event on the bulletin board. 

• Sponsored event for $1,000. 

• Encouraged the public and City employees to participate in the event, which 

included 23 participants. 

• Provided watershed specific fact sheets to volunteers.

I Love a Clean San Diego Trash Cleanup Sponsorship 

SDR-A9B 


Each spring, I Love A Clean San Diego (ILACSD) conducts its Creek to Bay Cleanup 

event to target various inland and coastal sites in San Diego County in need of trash 

and debris removal. ILACSD recruits and organizes site captains and groups of 

volunteers for each site. A media center is also designated, which promotes 

environmental stewardship, including the importance of keeping litter and debris from 

spoiling the region’s watersheds. The whole event is marketed throughout San Diego 

County through a variety of media, including television, radio public service 

announcements, newspapers, newsletters, electronic mail, bulletin boards, community 

outreach activities, calendar listings, and word of mouth. 

The ILACSD Creek to Bay Cleanup occurred on April 24, 2010. The City of San Diego 

(City) sponsored the Mission Valley Preserve site in the San Diego River Watershed 

Management Area (WMA). Approximately 202 volunteers removed 8,400 lbs of trash 

and over a half-mile area. 

The City requests that the Regional Board accept this activity as a watershed water 

quality activity for FY 2010 as the effectiveness assessment below demonstrates that 

this activity resulted in a measurable pollutant load reduction (Outcome Level 4) during 

the reporting period. 




The Creek to Bay Cleanup has historically been held in April of each year. Prior to that 

month, the City will coordinate with ILACSD staff to ensure that sites within the San 

Diego River WMA are included in the list for cleanups and that proper sponsorship 

arrangements are made.

• Volunteers from general public 


• Bacteria 

Page 1



Both the City’s Strategic Plan for Watershed Activity Implementation and the Collective 

Watershed Strategy for the San Diego River WMA identify bacteria as a high priority 

water quality problem throughout the San Diego River WMA, and recommend 

implementing load reduction/source abatement activities to address it. Sponsorship of 

the Creek to Bay Cleanup will result in load reduction of trash and debris directly and of 

bacteria indirectly.

Objectives 

The goal of this assessment is to determine the effectiveness and efficiency of trash 

cleanup days for actively reducing pollutant loads. 

Analysis and Results 

On April 24, 2010, 202 participants removed approximately 8,400 pounds of trash and 

debris from numerous sites in the San Diego River WMA. The average estimated 

sponsorship cost was $5,000 per watershed ($30,000/6 watersheds). Thus, there was 

a 8,400 pound load reduction associated with sponsorship per yearly event, and an 

efficiency of $0.60 per pound collected. The efficiency was calculated by dividing the 

sponsorship cost for the San Diego River WMA by the total pounds of trash removed 

and recycled.


Conclusions 

Implementation and assessment of load reduction and efficiency for the ILACSD Creek 

to Bay Cleanup will occur again in FY 2011. Future results may be used to compare 

various types of trash cleanups completed and their associated costs as well as 

comparing the same types of trash cleanups that are sponsored each year over time. 

Based on the total amount of trash removed leading to a load reduction of bacteria, a 

high priority water quality problem, this trash cleanup activity fulfills a watershed water 

quality activity for FY 2010.

TITLE: 

Increased Dry Weather Monitoring for Bacterial Indicators in Suspected 

Problem Areas 


The San Diego Municipal Storm Water Permit (Orders No. 2001-01 and 2007-0001) 

requires Copermittees to conduct annual dry weather monitoring. In an effort to better track 

and eradicate bacteria as well as other pollutants of concern, the City of Santee conducts 

an additional round (total of two rounds) of dry weather monitoring each year. 


• City of Santee 


• Bacteria 


Fecal coliforms are designated as a 303 (d) impairment in the San Diego River. The City 

of Santee is required to conduct dry weather monitoring of bacterial indicators once a year 

under its municipal permit. Bacterial indicators monitored included total coliforms, fecal 

coliforms and enterococci. Additional monitoring will be conducted on behalf of the City of 

Santee to facilitate the detection of illegal connections and discharges of fecal matter to 

the MS4. This activity is consistent with WURMP Strategic Goal 5 for Bacteria Source 

Reduction. 


Two rounds of dry weather monitoring for bacterial indicators (only one is required under 

the municipal permit).



TITLE: 

Park Appreciation Day 


The City of La Mesa (City) has been focused on eliminating pollutants from entering our 

receiving water bodies. Consequently, the City has organized a Park Appreciation Day for 

volunteers to remove trash and debris from local parks. Park Appreciation Day takes 

place once a year and is independent of the Adopt-A-Park Program. This event took place 

on October 24, 2009. The event was held at seven parks located within the San Diego 

River Watershed in La Mesa. The amount of debris removed during Park Appreciation Day 

was 12.9 tons. 









There are seven parks in the City of La Mesa that fall within the San Diego River 

Watershed. Organization of the Park Appreciation Day enabled residents to participate in 

cleaning up the environment with in the San Diego River Watershed. Trash and debris as 

well as green waste was collected and disposed of appropriately. This event is considered 

a long-term annual activity. 



• Cleaned seven parks within the San Diego River Watershed. 

• Collected approximately 12.9 tons of trash and debris. 

• Watershed related information was conveyed by group leaders to all 

participants.

TITLE: Pet Waste Bacterial Load Reduction/Doggie Bag Dispenser Program 


The installation of “Doggie Bag” dispensers provides pet owners with bags to collect 

their pet’s fecal matter for proper disposal (i.e., in a trash bin). This reduces the 

accumulation of pet fecal matter in public places, which otherwise would eventually be 

washed into storm drain facilities and into the watershed. An additional benefit is public 

health, as it prevents other park users (such as children) coming into contact with the 

excrement. 

This activity is also associated with public awareness and outreach. By placing the 

dispensers and accompanying signage, including municipal code sections, the public 

becomes aware that not picking up after their pets is a violation of the municipal code 

and negatively impacts the environment. 


• County of San Diego 




WATERSHED PRIORITY WATER QUALITY PROBLEMS ADDRESSED 




The Pet Waste Bacterial Load Reduction Program is considered an important activity in 

the watershed because it will reduce bacteria and oxygen demand loads into the storm 

drain system. This is a long-term activity; however, it will be assessed and adjusted on 

an annual basis through the annual reporting process. Two important goals of this 

program are to reduce the amount of pet waste found in parks and to educate the public 

on the need to clean up after their pets. Realization of these goals will thereby result in 

the reduction of a source of pollutants, most notably bacteria and nutrients, which could 

be released into the watershed. This activity is also consistent with WURMP Strategic 

Goal 5 for Bacteria Source Reduction. 

TASKS IMPLEMENTED DURING FY 2008-09 

The following tasks were implemented during FY 2008-09 as part of the Pet Waste 

Bacterial Load Reduction Program in the San Diego River Watershed: 

County of San Diego 

The County’s jurisdictional goal for this five-year permit cycle is to increase the total 

number of parks with pet waste bag dispensers by 100% (i.e., from 26 parks to 52 

parks). During the FY 2008-09 reporting period, the County added two new dispensers 

Page 1


and continued to maintain 28 dispenser stations at a total of 11 parks within the San 

Diego River Watershed. Dispenser locations include: 

• Cactus Park (2 new dispenser, 3 total dispensers)

Reserve: 

• Assumption 1: The average weight of pet waste per bag is approximately 0.2 lbs 

• Assumption 2: In addition to the bags taken from the County’s dispensers, an 

additional 30% of pet waste bags are brought to the parks by the pet owners 

themselves. 

TASKS IMPLEMENTED DURING FY 2009-10 

The following tasks were implemented during FY 2009-10 as part of the Pet Waste 

Bacterial Load Reduction Program in the San Diego River Watershed: 


The County’s jurisdictional goal for this five-year permit cycle is to increase the total 

number of parks with pet waste bag dispensers by 100% (i.e., from 26 parks to 52 

parks). During the FY 2009-10 reporting period, the County continued to maintain 28 

dispenser stations at a total of 11 parks within the San Diego River Watershed. 

Dispenser locations include:

City of Santee 

The City of Santee maintained “Doggie Bag” dispensers at all public parks, along 

Forester Creek and along Cuyamaca Street, a popular dog walking location. Additional 

Doggie Bag dispensers were installed at Mast Park (4 dispensers), Big Rock Park (1 

dispenser), West Hills Park (1 dispenser), Woodglen Vista Park (2 dispensers) and 

Magnolia Avenue at Princess Joann (1 dispenser). The City encourages residents to 

cleanup after their pets. Approximately 240,000 bags were used during this reporting 

period. Using the results of the San Elijo study, this is estimated to represent 

approximately 48,000 pounds of pet waste eliminated from the watershed, which 

Page 3


constitutes a load reduction in both pet waste and bacteria from entering the storm 

water conveyance system. 

City of La Mesa 

The City of La Mesa maintains pet waste bag dispensers throughout all City parks with 

half the parks in the City located in the San Diego River Watershed. The City 

encourages residents to clean up after their pets. Approximately 12,150 bags were used 

during this reporting period. Using the results of the San Elijo study, this is estimated to 

represent approximately 3,250 pounds of pet waste eliminated from the watershed, 

which constitutes a load reduction in both pet waste and bacteria from entering the 

storm water conveyance system. 

City of El Cajon 

“Doggie Bag” dispensers were set up at Wells Park – Dog Park to provide pet owners 

with bags with which they can collect their pet’s fecal matter for proper disposal (i.e., in 

a trash bin). During the 2009-2010 reporting period, the City conducted provision and 

maintenance of doggie bag dispensers at the Dog Park. It is estimated that City Parks 

crews removed over 40,000 pounds of pet waste from pet waste dispensers. 

TASKS PLANNED FOR IMPLEMENTATION DURING FY 2010-11 

Copermittees involved will continue to maintain “Doggie Bag” dispensers and to monitor 

the usage of bags. In addition, jurisdictions will increase the number of dispenser 

locations as appropriate. For example, the County has established a jurisdictional goal 

for this five-year permit cycle to increase the total number of parks with pet waste bag 

dispensers by 100% (i.e., from 26 parks to 52 parks). 


Effectiveness assessments for each jurisdiction’s pet waste bacterial load reduction 

activities are discussed in the implementation section above.

San Diego River Park Foundation Cleanup Event Sponsorship 

SDR-A14 

ACTIVITY DESCRIPTION 

The City of San Diego (City) will partner with the San Diego River Park Foundation 

(SDRPF) in an effort to help raise awareness of the pollution, bacteria, and sediment 

issues affecting the San Diego River. The City will provide funding for a number of 

SDRPF initiatives, including the annual River Days event designed to promote 

awareness of the pollution issues surrounding the San Diego River. Additionally, 

funding will support the SDRPF’s Clean and Green Team, a volunteer program 

designed to remove trash and plant native plants within the San Diego River Watershed 

Management Area (WMA). Funding will also be used to support public cleanups and 

other educational endeavors. 

FY 2010 activities included funding of the SDRPF’s Clean and Green Sponsorship. 

One year of support was provided for the Clean and Green Team. Funding went to: 

• removal and hauling of debris; 

• purchase of tools and supplies; 

• printed materials for volunteers; and 

• staff time at the events. 

The City sponsored twenty-eight cleanup events. A total of 93,775 pounds of trash was 

removed and 6,087 hours of volunteer service occurred through the twenty-eight 

cleanup events. 




The City will coordinate with SDRPF to provide funding for various projects throughout 

FY 2011 and beyond. Cleanups will be scheduled as appropriate. Trash Cleanup 

Events efforts take place throughout the year, and River Days is scheduled to occur in 

May of each year. 

PARTICIPATING WATERSHED COPERMITTEE(S) 



• San Diego River Park Foundation 

• REI

• Bacteria 


The Collective Watershed Strategy identifies bacteria as a high priority water quality 

problem in the San Diego River WMA. Providing funding to SDRPF will increase 

awareness of the bacteria and pollution issues surrounding the San Diego River, and 

the various cleanup initiatives will assist in reducing pollution throughout the San Diego 

River WMA. 

Partnership with SDRPF will provide funding to address bacteria indirectly by removing 

a bacterial source: trash. Literature published by the United States Environmental 

Protection Agency on its website 1 states that debris may be contaminated by pathogens 

that have adverse effects on humans. By decreasing the amount of trash, bacteria loads 

are reduced. Funding SDRPF’s public education and outreach programs will help 

increase awareness of the pollution issues affecting the San Diego River and foster 

appropriate behavior change.

Objectives 

The goal of this assessment is to determine the load reduction effectiveness and 

efficiency of the sponsored cleanup. 


FY 2010 activities included funding of the SDRPF’s Clean and Green Sponsorship. 

One year of support was provided for annual river clean-ups and other activities, the 

purchase of supplies, trash removal and disposal, volunteer support, and direct staff 

support of program. The City sponsored twenty-eight events. Over the course of the 

twenty-eight events, 93,775 pounds of trash were removed and 6,087 hours of 

volunteer service occurred. The efficiency of the twenty-eight cleanup events was 

$0.0.35 per pound, calculated by dividing the total sponsorship cost by the total pounds 

of trash and debris removed and recycled during all twenty-eight events. 

Conclusions 

This activity fulfills a watershed water quality activity for FY 2010 as the effectiveness 

assessment demonstrates this activity resulted in a measurable pollutant load reduction 

during this reporting period. 

The City will coordinate with SDRPF to provide funding for various projects throughout 

FY 2011 and beyond. Cleanups will be scheduled as appropriate. Clean and Green 

Team efforts take place throughout the year, and River Days is scheduled for May of 

each year. Implementation and assessment of load reduction and efficiency of these 

cleanups will occur again in FY 2011. Future results may be used to compare various 

types of trash cleanups completed and their associated costs as well as comparing the 

same types of trash cleanups that are sponsored each year over time. Effectiveness of 

public outreach and educational will be measured via citywide surveys comprised of 

residents in the San Diego River WMA to determine awareness and knowledge 

retention of water quality issues, as well as changes in behavior. Additionally, water 

quality monitoring will be conducted throughout the San Diego River WMA to determine 

whether improvements have occurred.

San Diego River Geographically Based Business Property and 

Facility Inspections 

SDR-A15 


This activity is part of a larger study in the San Dieguito River, Los Peñasquitos, Mission 

Bay and La Jolla, and San Diego River watershed management areas (WMAs). The 

City of San Diego (City) developed and implemented a focused inspection activity 

designed and implemented to answer the following management questions related to 

the implementation of commercial/industrial inspection programs: 

1) What activities and locations at businesses should be targeted during the 

inspection based on severity of observed/report issues? 

2) Does the City’s commercial/industrial inventory need to be reevaluated 

(additions of business types or modifications to prioritization process)? 

3) Based on information collected during inspections, can the inventory of 

specific source types, be feasibly prioritized based on site specific 

characteristics? 

The City delineated a specific area within the San Diego River WMA. Inspections were 

conducted within this geographic area, both inspecting properties as a whole, and 

evaluating and inspecting individual businesses regardless of whether they were 

included in the City’s commercial/industrial inventory. A mixture of individual 

businesses and multi-suite complexes, such as industrial parks and shopping centers, 

were located in this selected geographic area. Two types of data collection were 

performed at the overall property level: geographic property evaluations and property 

inspections. Two types of additional data collection at the individual business level on 

these properties were also conducted: pre-contact and post-contact inspections. 

Details of these evaluations and inspections are included below: 

• Property level data collection: 

o Geographic property evaluations, referred to as “geographic evaluations” 

for short, recorded detailed information about landscaping, trash/disposal 

areas, and storm drains within a given property. The purpose of the 

property evaluations was to characterize the area and collect data 

additional data beyond the scope of a typical inspection to be used for 

assessment purposes. For example, a typical inspection answers the 

question of whether trash areas at a site are clean enough to meet the 

City’s BMP requirements. During property evaluations, more detailed 

information was recorded: the number of trash areas at a property and the 

type(s) and quantities of trash observed in them (outside the dumpsters) 

were recorded. 

o Property inspections were performed at shopping centers and industrial 

parks. Property inspections gathered information about shared areas 

Page 1


such as landscaping, trash/dumpster areas, parking lots, outdoor material 

storage, and high threat to water quality activities. Typically, these areas 

are the responsibility of the property owner or property management 

company. These inspections were based solely on information gathered 

through observations and focused mainly on compliance evaluation. 

• Individual business level data collection: 

o Pre-contact business inspections were performed based on the 

inspectors’ observations only and before speaking with facility 

representatives. These inspections were performed at all types of 

businesses on the City’s industrial and commercial inventory. Pre-contact 

business inspections were not conducted at facilities for which site access 

required contact with site personnel or for facilities that appeared likely not 

to be inventoried. 

o Post-contact business compliance inspections were conducted at 

businesses that inspectors determined were or would likely need to be 

included on the City’s industrial and commercial inventory based on precontact 

inspection results and were completed after the pre-contact 

inspections. The post-contact business inspection involved the same 

steps as a standard industrial and commercial inspection under the City’s 

JURMP industrial and commercial inspection program. A post-inspection 

was only conducted if a pre-contact inspection was completed. 

Educational material was distributed, as applicable, during post-contact 

inspections. 

In FY 2010, 18 geographic evaluations, 15 property inspections, 100 pre-contact 

business inspections and 88 post-contact industrial/commercial inspections, were 

conducted in the area selected in the San Diego River WMA. 




This project was implemented in FY 2009 and FY2010. Assessment and reporting on 

this activity were completed in June 2010.

Objectives 

The goal of this assessment is to determine if evaluating facilities based on observation 

only is an effective and efficient method for identifying and eliminating storm water 

pollution sources generated on industrial/commercial sites. Furthermore, this program 

aimed to identify potential sources of constituents of concern in the San Diego River 

watershed by assessing industrial and commercial areas, businesses, and activities in 

the selected geographic areas. 


A total of 97% of properties evaluated during geographic evaluations were observed to 

have some evidence of over-irrigation. Additionally, 95% of storm drains were observed 

to have some level of accumulated trash, litter, and/or sediment. Lastly, 74% of trash 

areas were observed to have accumulated trash, debris, and/or sediment. 

All of the properties that received property inspections had at least one corrective 

action. Most were relatively minor corrections, but 40% of the properties that received 

property inspections had corrective actions requiring further follow-up. A total of three 

IC/IDs were observed during property inspections. Based on the inspections performed 

and the recorded time for each inspection, it appears that a property inspection is an 

effective and efficient method for identifying major outdoor activities and storage that 

contribute to storm water pollutant runoff. Overall property inspections do not provide 

much ability to assess BMPs for activities outside accessible common areas, but at 

shopping centers and industrial parks, it is very rare for activities with potential to 

influence storm water quality to occur outside areas that can be accessed without first 

contacting a business representative. Occasionally, it was difficult for the inspectors to 

clearly delineate a property. Different parcels located close to one another can appear 

to be part of the same property complex, but may actually have different parcel owners. 

Page 4


As previously mentioned, business inspections were conducted in two parts, the precontact 

inspection and the post-contact inspection. Pre-contact inspections are faster 

and were effective at identifying outdoor BMP implementation deficiencies at properties, 

such as shopping centers and industrial parks with accessible areas. Pre-contact 

inspections were not as effective at identifying BMP deficiencies at sites that are more 

difficult to access or where potentially pollutant-generating activities are conducted in 

areas closed off to the general public, such as auto repair shops. It should be noted 

that during pre-contact inspections BMP implementation problems could be identified, 

but it was often not possible to identify the responsible party without talking to personnel 

at the site. The number of pre-contact inspections is greater than the number of postcontact 

inspections because in several instances the pre-contact inspection was 

performed, but after talking with facility personnel during the post-contact inspection the 

inspector determined that the facility was not conducting activities for which inclusion on 

the industrial/commercial inventory was required. The percentage of sites that required 

corrective actions increased slightly between the pre- and post-contact inspections, 

98% and 100% respectively. Pre-contact inspections yielded 14 IC/IDs since the 

responsible party could not be identified; however, during the post-contact inspections, 

the number of IC/IDs decreased because the responsible parties were narrowed down 

to three. 

Conclusions 

This activity fulfills the requirement of one of the two required watershed water quality 

activities for this watershed management area. 

Based on the gathered information, pre-contact inspections of an overall complex 

assessment with shared areas is an efficient and effective in identifying BMP 

implementation deficiencies in outdoor areas for shopping centers and industrial parks, 

but less so for individual businesses that are more difficult to access or areas closed to 

the public, such as contractor storage yards or automotive repair shops. 

Based upon the two year inspections results, the primary areas and activities that 

should be focused on during inspections are: 1) Over-Irrigation; 2) Trash Areas; and 3) 

Storm Drains. In addition, there were no other businesses warranted to be on the 

industrial/commercial inventory. 

As a result of this activity during the post-contact business inspections, the City noted 

deficiencies at the facilities and made recommendations to the responsible parties at 88 

sites. Additionally, the City noted 37 sites that needed to follow-up to verify that 

corrective actions/BMPs were implemented. However, the City can verify at ten 

locations, corrective actions were immediately taken. This demonstrates both Level 3 

(change in behavior/BMP implementation) and Level 4 (source abatement/load 

reduction) outcomes were achieved as a direct result of this activity. Also, in this 

watershed, the City confirms three IC/IDs were observed and called into the City’s 

hotline for response and follow-up for abatement.

• Trash 

• Bacteria (indirectly through trash) 


Page 1


This activity removes trash within the watershed and thereby reduces the potential 

breeding of bacteria within the watershed, which is consistent with the WURMP Strategic 

Goal 5 for Bacteria Source Reduction. It also enabled residents to participate in enhancing 

the watershed environment by removing trash. Trash and debris was collected and 

disposed of appropriately. Reduction of the pollutant load can be assessed based on the 

weight of material collected. In addition, neighborhood enhancement activities can instill a 

sense of pride in the appearance of the neighborhood, providing a disincentive to allow 

trash to accumulate again. Removal of invasive species can benefit the riparian 

environment. 


The following tasks were conducted as part of these public participation and education 

activities during Fiscal Year 2009-2010: 

• Eleven trash removal events were conducted adjacent to the San Diego River or 

Forester Creek. 

• Removal of over 24,840 pounds of trash. 

• Public participation and education.

Cabrillo Heights Park Rain Garden Infiltration Project 

SDR-A19 


This activity involves the implementation of a large scale low impact development 

(LID) project in the San Diego River Watershed Management Area (WMA) to 

reduce runoff volume. The large scale LID site selection focused on city owned 

parks and parcels that would be suitable for infiltrating off site flow. Site visits 

were performed to evaluate the field conditions at approximately ten sites in FY 

2007 through FY 2008. Cabrillo Heights Park was eventually selected as the site 

of choice for the Rain Garden Infiltration Project. 

The concept for this park includes the installation of rain gardens at two sites 

within the park. The rain gardens, or bioretention basins, will be used to trap 

particulate pollution, encourage evapotraspiration, and reduce the amount of 

trash, oils and grease that make its way to the storm drain system. Flows are 

mainly filtered through the rain garden, collected, and returned to the storm drain 

system. A portion of the storm water will remain within the planted bed and be 

used by plants for evapotranspiration and growth. 

The first site, located on the western edge of the park, will be used to treat storm 

flows from the western parking lot on Kearny Villa Road. All parking lot flows will 

enter into the storm distribution piping through a couple of storm water catch 

basins located in the parking lot. These catch basins shall include grating to 

prevent large solids from entering into the piping, and inserts to prevent trash and 

other debris from entering the rain garden. PVC storm drain piping will convey 

the parking lot flows to the rain garden located at the southern end of the parking 

lot. 

The second site is located on the eastern portion of the park and will treat flows 

from Angier Elementary School and a sporting event parking lot on the east side 

of the park. All flows from these two locations are directed to two existing 

separate catch basins; one dedicated for school flows, and one for parking lot 

flows. Distribution piping will capture flow from these two locations and convey it 

to the rain garden. 




The project was transferred to the Preliminary Engineering section of the 

Engineering & Capital Projects Department in September 2008 for the purpose of 

managing the project through final design, construction and project closeout. The 

Page 1


project is currently in the process of hiring a design consultant. Project design is 

anticipated to begin in November 2010 and continue into FY 2012. Construction 

is anticipated to begin in FY 2012. Water quality monitoring will be conducted 

before and after construction to assess the effectiveness in reducing runoff 

volume and pollutant loading.

Management Practice (BMP) retrofits. The load reduction efficiencies will also be 

estimated and used to determine the efficacy of future LID BMP implementations. 


Site visits were performed to evaluate the field conditions at approximately ten 

sites in FY 2007 through FY 2008, and Cabrillo Heights Park was eventually 

selected as the site of choice for the Rain Garden Infiltration Project. 

Conclusions 

Anticipated future monitoring will be conducted to assess pollutant removal 

efficiencies.

Coastal Cleanup Day Sponsorship 

SDR-A20 


Each fall, San Diego Coastkeeper (SDCK) conducts the Coastal Cleanup Day event to 

target various inland and coastal sites in San Diego County in need of trash and debris 

removal. Coastkeeper recruits and organizes site captains and groups of volunteers for 

each site. A media center is also designated, which promotes environmental 

stewardship, including the importance of keeping litter and debris from spoiling the 

region’s watersheds. The whole event is marketed throughout San Diego County 

through a variety of media, including television, radio public service announcements, 

newspapers, newsletters, electronic mail, bulletin boards, community outreach activities, 

calendar listings, and word of mouth. 

Coastal Cleanup Day occurred on September 19, 2009. The City of San Diego (City) 

sponsored the Mission Valley Preserve site in the San Diego River Watershed 

Management Area (WMA). Approximately 70 volunteers removed 4,280 pounds of 

trash and debris over a one-mile area. Volunteers were asked to track the debris 

collected by filling out data cards provided by the Ocean Conservancy. 

Based on the information above, the effectiveness assessment below, and the total 

amount of trash removed leading to a load reduction of bacteria, a high priority water 

quality problem, this trash cleanup activity fulfills credit as a watershed water quality 

activity for FY 2010.

Coastal Cleanup Day has historically been held in September of each year. Prior to that 

month, the City will coordinate with Coastkeeper staff to ensure that sites within the San 

Diego River WMA are included in the list for cleanups, and that proper sponsorship 

arrangements are made.

Objectives 

The goal of this assessment is to determine the effectiveness and efficiency of trash 

cleanup days for actively reducing pollutant load. 


The event’s debris removal was tracked using data cards provided by the Ocean 

Conservancy; 70 participants removed 4,280 pounds of trash and debris. The average 

estimated sponsorship cost was $5,000 per watershed ($30,000/6 watersheds); thus, 

Page 2


there was a 4,280 pound load reduction and an efficiency of $1.17 per pound collected. 

The efficiency was calculated by dividing the sponsorship cost for the San Diego River 

WMA by the total pounds of trash removed and recycled. It is anticipated that the 

sponsorship fee at that level would remain the same for subsequent years. 

Conclusions 

Implementation and assessment of load reduction and efficiency for the Coastal 

Cleanup Day sponsorship will occur again in FY 2011. Future results may be used to 

compare various types of trash cleanups completed and their associated costs as well 

as comparing the same types of trash cleanups that are sponsored each year over time. 

Based on the total amount of trash removed leading to a load reduction of bacteria, a 

high priority water quality problem, this trash cleanup activity fulfills a watershed water 

quality activity for FY 2010.

LAND ACQUISITIONS 

SDR-A23 


The San Diego County Board of Supervisors approved the Multiple Species Conservation 

Program (MSCP) in 1997 as an integral part of the County’s efforts to protect parks and open 

space. The goal of the MSCP (a 50-year program) is to maintain and enhance biological 

diversity in the region and maintain viable populations of endangered, threatened, and key 

sensitive species and their habitats. Land acquisition also provides a significant water quality 

benefit for the watersheds in which it occurs. MSCP acquisition precludes development from 

occurring and allows land to retain its natural ability to infiltrate stormwater/runoff. 

The MSCP is a cooperative effort among the County and other local jurisdictions and the U.S. 

Fish and Wildlife Service and the California Department of Fish and Game (the Wildlife 

Agencies). These public partners work with various private landowners, conservation groups, 

and community planning groups, developers, and other stakeholders. The County of San Diego 

has adopted an MSCP for the southwestern portion of the County. MSCP plans for the Northern 

and Eastern portion of the County are in the planning stages. It is expected that the Northern 

Subarea Plan may be approved during the lifetime of the current stormwater permit. While the 

northern and eastern plan have yet to be approved by the County of San Diego, lands have been 

and will continue to be acquired from willing sellers. 


During the FY2009-10 reporting period there were no land acquisitions in the San Diego River 

Watershed. It is expected that acquisitions will continue if land becomes available within the 

watershed. 

During the FY2008-09 reporting period there were 557.50 acres of land acquired in the San 

Diego River Watershed. The current acquisitions are shown in the table below.

Land acquisition is consistent with the collective watershed strategy and the Strategic Goals of 

the WURMP in that it averts development, thereby eliminating the possibility of future sources 

in need of abatement or future pollutant loads in need of reduction. 


Activity effectiveness will be measured by tracking the number and total acreage of land 

acquisitions within the watershed on an annual basis. It may also be possible to estimate 

pollutant loadings avoided as a result of these acquisitions. The County will consider presenting 

load reduction estimations in WURMP Annual Reports if it determines that they are helpful for 

the purposes of assessing overall program effectiveness.

TITLE: Forester Creek Debris Barrier 


The City of El Cajon Public Works Department (City) installed a debris barrier. 

The debris barrier was custom manufactured for Forester Creek and placed to 

intercept plastic bottles, Styrofoam cups, paper, shopping carts, and other 

debris. The barrier was strategically placed in an area adjacent to the City’s 

Public Works Maintenance Yard best suited for prompt cleanup following 

significant storm events and before it can reach the San Diego River. 

PARTICIPATING JURISDICTIONS/ORGANIZATIONS 




• Sediment 

• Bacteria (indirect through trash and sediment; high priority) 


The removal of trash and debris in the San Diego River is important in order to 

improve water quality in the river. Trash and debris enters the storm water 

system, Forester Creek and eventually the San Diego River and the Pacific 

Ocean, posing a threat to wildlife and human health. The debris barrier controls 

and contains trash and other debris reducing pollutants from ultimately 

discharging into the San Diego River. This activity is an ongoing long-term 

activity and trash and debris will continue to be collected and monitored. This 

activity is consistent with WURMP Strategic Goal 5 for Bacteria Source 

Reduction. 


Collection and removal of a total of 282.5 cubic yards of trash and debris was 

conducted as part of maintenance activities by the City of El Cajon. The collection 

of trash and debris was as follows: 

• Assorted Trash/Debris = 13.5 Cubic Yards 

• Organic Materials = 81 Cubic Yards 

• Sediment = 188 Cubic Yards



TITLE: Forester Creek Debris Barrier 


The City of Santee installed a debris barrier in as part of the Forester Creek 

Improvement Project. The debris barrier was custom manufactured for Forester 

Creek and placed to intercept plastic bottles, Styrofoam cups, paper, shopping 

carts, and other debris. The barrier was strategically placed adjacent to the 

Prospect Avenue Bridge where the creek transitions from concrete-lined to 

unlined. 

PARTICIPATING JURISDICTIONS/ORGANIZATIONS 




• Sediment 

• Bacteria (indirectly through trash and sediment; high priority) 


The removal of trash and debris in the San Diego River is important in order to 

improve water quality in the river and also indirectly for reducing bacteria loads. 

Trash and debris enters the storm water system, Forester Creek and eventually 

the San Diego River and the Pacific Ocean, posing a threat to wildlife and human 

health. The debris barrier controls and contains trash and other debris reducing 

pollutants from ultimately discharging into the San Diego River. This activity is an 

ongoing long-term activity and trash and debris will continue to be collected and 

monitored. This activity is consistent with WURMP Strategic Goal 5 for Bacteria 

Source Reduction. 


Trash and debris were removed as needed from the barrier. In addition, 

approximately 2,000 lbs was removed using a volunteer event after the first 

major storm of the 09-10 rainy season. The City recognized that the trash 

needed to be promptly removed prior to the next forecast storm, so it contacted 

this volunteer organization to provide the additional manpower to accomplish this 

task in a timely manner. The City provided staff, equipment and the trash 

disposal service, in addition to coordinating the event.

San Diego River Watershed Municipal Rain Barrel 

Installation and Downspout Disconnect Project 

SDR-A25 


During FY 2010, the City of San Diego (City) completed a municipal rain barrel 

installation and downspout disconnect project that reduced pollutant loading at 

municipal facilities. The municipal rain barrel installation and downspout 

disconnect project consisted of installing rain barrel systems, including 

downspout disconnects and infiltration systems, within the San Diego River 

Management Area (WMA) to reduce pollutant loading from urban runoff during 

storm events. 

The project included site evaluations and selections, the purchase of rain 

barrel/downspout disconnect systems and planter boxes, system installation, 

wet-weather monitoring, and effectiveness assessments. 

In order to select appropriate sites for this pilot project, the City used the 

prioritization process outlined in its Strategic Plan for Watershed Activity 

Implementation to target high priority areas within the San Diego River WMA. 

The site selection process was long and iterative. Field reconnaissance was 

required to identify sites within the San Diego River WMA with adequate roof 

gutters, downspouts, and locations where rain barrels would be installed 

to capture flow. Sites were assessed for sources of electrical power for use with 

automated systems and for adjacent vegetated areas where captured water 

could be discharged. Sites were also selected for education/outreach 

opportunities. 

Based on the prioritization plan and field reconnaissance, the Mission Trails 

Regional Park Visitor Center was selected because it is located in one of the 

highest priority sectors of the San Diego River WMA for potential pollutant 

loading. The visitor center is also a publicly accessible City facility, making 

education and outreach opportunities easily implementable. 

In April 2009, a City-approved contractor installed two rain barrel systems at the 

visitor center. One 54-gallon rain barrel was installed below grade adjacent to 

the main entrance to the back patio. The rain barrel was placed directly 

underneath an existing roof drain. This system uses an automated timer and 

pump to release captured runoff to adjacent landscaping. A rain chain 

connecting the roof drain to the rain barrel was also installed to direct runoff from 

the roof to the rain barrel below. A second 54-gallon rain barrel was also 

installed below grade along the back patio area. This system also uses an 

automated timer and pump but does not include the use of a rain chain.

A one page informational flyer regarding the rain barrel pilot project was 

developed in June 2009. The flyer was distributed to all participating municipal 

sites to be made available to the public. In addition, a brief description of the 

pilot project and a PDF version of the informational flyer were posted on the 

City’s Think Blue website during the first quarter of FY 2010. 

During FY 2010 the City assessed the effectiveness of the rain barrel/rain 

harvesting systems the Mission Trails Regional Park Visitor Center. Ultimately, 

the City would like to incorporate the use of these LID techniques into a 

residential program that may include incentives for implementing these systems 

on a larger scale. However, this phase of the project is now complete and will no 

longer be included in future reporting updates. 


• None 


Project planning, including site selection, began in July 2007 and was completed 

by the first quarter of FY 2008. Initially, the project was scheduled for completed 

by the fourth quarter of FY 2008. However, planning, site selection, and 

procurement of the rain barrels took longer than expected. Product screening for 

the rain barrels and concrete planters was completed in the first quarter of 2008. 

Procurement of rain barrels, planter boxes and rain chains concluded by the 

second quarter of 2009. The installation contract was awarded and approved by 

City Council during the second quarter of FY 2009. A pre-construction meeting 

was held with the contractor in March 2009. Installation of all systems occurred 

in April 2009. Wet-weather monitoring was performed from October 2009 to April 

2010. Assessment and final reporting for this program concluded in June 2010.

Page 3


Objectives 

The goal of the rain barrel and rain harvesting assessment was to determine 

whether rain barrel/rain-harvesting systems reduce storm water runoff, thereby 

reducing metals and bacteria loads, and if so which system is most effective and 

efficient. 


The pilot project was assessed in FY 2010 based on monitoring data from two 

storm events collected over one wet-weather season. The one system at the 

Mission Trails Regional Park Nature and Visitor Center captured and attenuated 

14.4 cu ft of rainwater over the two monitored storm events. The average 

pollutant concentrations of the runoff were 51 µg/L for copper, 6 µg/L for lead, and 

136 µg/L for zinc. Over the two monitored storm events, the 54-gallon capacity 

automated system configuration at the Mission Trails Visitor Center resulted in 

load reduction of 4 grams of copper and 0.1 grams of zinc. 

The total cost of installation, operation, maintenance, and effectiveness 

assessment for the one system at Mission Trails Regional Park Nature and 

Visitor Center was approximately $7,559. 

Assessment data at this site shows that the gravity-flow system configuration, 

consisting of a rain barrel and/or downspout disconnect that discharges to 

adjacent landscaping, is more effective and reducing pollutant loads and 

attenuating wet weather flows than other systems tested. Overall, the study 

found that gravity-flow systems can attenuate and infiltrate up to six times their 

capacity in storm water runoff, in addition to capturing and redirecting pollutants 

away from the MS4. Furthermore, this configuration was the least expensive of 

the three tested, which makes it the most cost-efficient. Water quality monitoring 

data also confirmed that buildings with copper or galvanized metal roofs 

represent significant sources of copper and zinc, respectively. 

Conclusions 

Assessment data shows that rain barrels and downspout disconnects are a lowcost, 

effective BMP for both attenuating storm water flows and reducing pollutant 

loads. Although less effective than gravity-flow systems at addressing pollutant 

loads, rain barrel and/or downspout disconnect systems with planter boxes are a 

viable option for sites lacking adjacent pervious areas. Based on an analysis that 

demonstrates that the activity resulted in a measureable pollutant load reduction 

(Outcome Level 4) during the reporting period, the Copermittees request that the 

Regional Board accept this activity as a watershed water quality activity for FY 

2010.

Park Ridge Boulevard Bacteria Treatment Project 

SDR-A26 


The City of San Diego will construct a new catch basin, storm drain, trash 

segregation unit, and bacterial treatment system at the southern terminus of Park 

Ridge Boulevard. A new catch basin will be placed along the western right-ofway 

south of the intersection with Murray Park Drive. The catch basin will be 

sized for the full design flow reaching that location. 

Flows up to an 85th percentile storm event will exit the catch basin and flow 

through a trash segregation unit, followed in series by the bacterial treatment 

system. Flows in excess of an 85th percentile storm will exit the catch basin via an 

overflow pipe and bypass the treatment system. 

A manhole will receive flows from both the treatment system and the overflow 

pipe. From that manhole, a new storm drain will convey flows to the outlet 

location for the existing storm drain system within the eastern Park Ridge 

Boulevard right-of-way. A new headwall sized to accommodate both outlets will 

be required at this location. 




The project was transferred to the Preliminary Engineering section of the 

Engineering and Capital Projects Department in September 2008 for the purpose 

of managing the project through final design, construction and project closeout. 

Design began February 2010 and is anticipated to continue through FY 2011. 

Construction is expected to be completed in FY 2013. Water quality monitoring 

will be conducted before and after construction to assess the effectiveness in 

reducing runoff volume and pollutant loading.

TITLE: Median Sweeping Pilot Study 1 



During FY 2010, the City of San Diego (City) implemented a one-year pilot study 

to assess the effectiveness of modifying its street sweeping program to include 

roadway medians and other non-traditionally swept thoroughfares adjacent to 

high traffic roadways. The pilot study specifically focused on assessing the 

potential water quality benefits, cost-efficiency, logistical constraints, and public 

outreach requirements associated with this proposed programmatic change to 

the City’s street sweeping program. 

The pilot study specifically looked at expanding current street sweeping 

operations to include medians and other non-traditionally swept thoroughfares 

adjacent to high traffic roadways. Implementation of this programmatic change 

allowed calculation of potential pollutant removal efficiency afforded by sweeper 

access to what was found to be heavily polluted areas. 

The overall pilot study was designed to answer the following management 

questions: 

• What is the relative cost-efficiency of integrating additional median 

sweeping into the City street sweeping program? 

• What level and type of debris can be removed by sweeping high volume 

median areas? 

• What level of metals removal benefit does median sweeping provide? 

• What type of sweeping equipment optimizes debris removal in or on high 

volume median areas? 

This pilot study was used to determine whether sweeping medians improves the 

effectiveness of street sweeping activities. Water quality monitoring and/or 

debris volume monitoring was conducted to allow for assessment. This activity 

took place in multiple watersheds, including Friars Road in the San Diego River 

WMA. 

The City has adopted an integrated, tiered, and phased strategy to ensure the 

implementation of activities most efficient in protecting and improving water 

quality. This activity conforms to this strategic approach providing a phased 

approach. The Median Sweeping Pilot Study was piloted first to determine 

whether median sweeping improves the effectiveness of street sweeping 

activities before being considered for broad scale implementation. 

1 In the FY09 WURMP Annual Report, this activity was known as Route Posting and Median Sweeping 

Pilot Study. A more accurate title was chosen for this activity during project planning and implementation 

that took place in FY 2010.

• Total pounds of debris removed by land use (Outcome Level 4) 

• Frequency of removal correlated to pounds of debris removed 

(Outcome Level 1 and 4) 

• Post-sweeping COC concentrations in runoff (Outcome Level 4) 

Objectives 

The goal of the assessment was to investigate whether sweeping medians 

improves the effectiveness of the City’s current street sweeping activities. 


A baseline sweep of the four pilot median areas, which included Friars Road in 

the San Diego River WMA, resulted in the removal of 32,460 lbs of debris over a 

total of 58 miles with an average of 560 lbs of debris removed per mile swept. 

After the initial baseline sweep, each route was swept four more times over an 

approximate three month period (with roughly three weeks between sweeps). A 

total of 32,560 lbs of debris was removed over this three month study period. 

Conclusions 

The study results indicate that median sweeping has the potential to remove 

significant amounts of street debris from high-traffic City roadways. The initial 

baseline median sweep collected 3-5 times more debris than the subsequent 3- 

week interval sweeps. This suggests that there is a significant buildup of debris 

adjacent to median areas. Furthermore, debris sampling confirmed the presence 

of heavy metals, nutrients and hydrocarbons in the debris collected. This leads 

the City to believe that median sweeping may provide a significant benefit for 

controlling the input of high priority water quality problems from impacting 

receiving waters. Based on an analysis that demonstrates that the activity 

resulted in a measureable pollutant load reduction (Outcome Level 4) during the 

reporting period, the Copermittees request that the Regional Board accept this 

activity as a watershed water quality activity for FY 2010.

TITLE: Woodside Avenue Detention Basin 



In 2003, the County of San Diego received Proposition 13 funding from the State Water 

Resources Control Board (SWRCB) to perform conveyance restoration and construction 

of an extended detention basin (EDB) to treat urban runoff and low storm flows from a 

1.4 square mile area within Hydrologic Area (HA) 907.12 before discharging into Los 

Coches Creek and the San Diego River. The site is located in the unincorporated 

community of Lakeside on a vacant property adjacent to Woodside Avenue near Winter 

Gardens as shown in the attached figure. The constructed basin and concrete removal 

were designed to act as a demonstration for the effectiveness of similar BMPs at 

removing pollutants. A water quality monitoring component was also initiated to provide 

hard evidence of the BMP’s pollutant removal capabilities. Although the grant was 

completed in May 2007, the County continues to monitor the site to gauge its 

effectiveness at removing pollutants. 

ACTIVITY IMPLEMENTATION FY 2007-08

An initial effectiveness assessment of this project was conducted in 2006. The results 

were presented in detail in: Woodside Avenue Extended Detention Basin Effectiveness 

Assessment Monitoring Final Report, March, 2007, prepared by Weston Solutions. As 

previously described, additional monitoring is ongoing. 

Constituent concentrations at the outlet of the EDB were often higher than at the inlet. 

There were, however, overall load reductions for the majority of constituents measured 

during dry weather conditions (wet weather discharge rates were not measured; 

therefore, wet weather loadings could not be calculated for FY 2009/2010). This was 

most likely due to the EDB acting to absorb the runoff containing the pollutants before it 

was able to reach the outlet. The exceptions included total copper and zinc. The mean 

loadings of those constituents were higher at the outlet than at the inlet of the Woodside 

EDB due to the much elevated total zinc and copper loadings at the outlet observed on 

one of the three sampling dates (on March 3, 2010). 

In terms of constituent concentrations alone, it may be concluded that the EDB 

functioned well in reducing nitrate-N concentrations in non-storm flows and dissolved 

zinc concentrations during wet weather. The concentrations of other constituents 

measured, however, were not consistently reduced and were often higher at the outlet 

of the EDB. These often higher constituent concentrations at the outlet and the much 

higher total copper and zinc loadings at the outlet on one sampling occasion may have 

been due to the deposition of metals and dust near the outlet as it is located adjacent to 

a high-traffic road. 

Annual water quality sampling results for FY 2009-10, including load reduction 

estimates, are attached.

FY 2009–2010 Education Activity 

TITLE: 

ID NUMBER: 

Public Service Announcement: Karma Series 

SDR-A36 


The City of San Diego (City) retained a contract with a film production company 

to create three Think Blue Public Service Announcements (PSAs) specifically 

focused on bacteria, with gross pollutants (trash) profiled as a vector. The PSAs 

are entitled Karma, Karma Second Chance, and Karma Tourist and the goal of 

the PSAs is to educate the public about causes of pollution and to encourage 

positive behavioral change. 

These PSAs were developed in FY 2007 and FY 2008 and were broadcast on 

several TV and radio stations throughout the San Diego River Watershed 

Management Area (WMA) in FY 2009 and FY 2010. The PSA used humor to 

convey the importance of the public’s part in the proper disposal of trash and the 

impacts litter and pollution have on our waterways and beaches. The PSAs were 

broadcast in both English and Spanish. 

The City will continue to run the Karma public service announcements; however, 

this activity will no longer be included in future reporting updates.

high priority water quality problems in the WMA. The Karma, Karma Second 

Chance, and Karma Tourist Public Service Announcements will result in both 

increased knowledge and awareness regarding bacteria and trash as a vector 

and future load reduction of trash and debris directly and of bacteria indirectly. 


The City will continue to run the Karma public service announcements to educate 

the public, but no longer plans to use television advertising as part of its 

watershed program, therefore no assessment was conducted in FY 2010.

Oktoberfest 


The City of La Mesa is committed to education outreach at community events. Each year 

the City hosts an Oktoberfest Event. During the event on October 2-4, 2009 the City’s 

Storm Water Program staff ensured fact sheets were distributed to all Oktoberfest vendors 

regarding storm water pollution prevention. 







• Diazinon 

• Metals 



The City took steps to ensure that vendors were knowledgeable regarding pollution 

prevention during the event, which is located within the San Diego River Watershed.

TITLE: 

PUBLIC OUTREACH AND MEDIA 


During the reporting period, the City of Santee distributed articles specific to storm water in 

the periodic newsletter entitled “Santee Review’. The newsletter reaches potentially 21,500 

residential, commercial, and industrial addresses. The newsletter is intended to educate 

residents and visitors about watershed issues and to solicit their cooperation and 

participation. 




• Trash 

• Bacteria 

• Total Dissolved Solids 

• Low Dissolved Oxygen 


In order to change knowledge and awareness and effect behavioral changes, it is 

necessary to educate the general public. Public presentations/outreach and the media are 

an effective method in distributing our watershed message and informing others on how 

they can make a difference in our water quality and environment. 


The following articles were published as part of the Public Outreach Program during Fiscal 

Year 2009-2010: The articles included: 

• “Volunteers Assist with Creek Clean Up” describes how volunteers from the 

San Diego River Park Foundation worked with City crews to remove trash 

washed down to Forester Creek. It provided contact information for the River 

Park Foundation. 

• “Debris Recycled into Construction Material” described how sediment 

washed into Forester Creek from the upstream lined channel was removed 

and used in the Town Center Community Park project. 

• “Kids, Water and Bugs” described outreach to children at a City of Santee 

camp. There a simplified model of the storm drain system and river were 

used to demonstrate how pollution discharged onto our streets affects the 

San Diego River. Afterwards the children had an opportunity to examine 

some of the benthic macroinvertebrates that live in Forester Creek. This 

event was conducted in collaboration with the San Diego River Park 

Foundation. 

A postcard was previously developed to raise awareness amongst residents about the 

connection between the storm drain and the river and the need to properly dispose of

waste. The postcard also provides information on the free services provided by the 

City for the disposal household hazardous waste and large household items. This 

postcard was sent to approximately 81 residences.

San Diego River Watershed Restaurant Best 

Management Practices Booklet 

SDR-A43 


The City of San Diego (City) obtained permission from the County of San Diego 

to modify its What’s Cookin’? booklet, a guide for food and drinking 

establishments to implement Best Management Practices (BMPs), for distribution 

to City-permitted facilities within the San Diego River Watershed during 

inspections. In the FY 2005 Annual Report, this activity was originally reported 

as producing a flyer; however, after further evaluation, City staff determined that 

a booklet to supplement existing fact sheets passed out during inspections would 

be more effective in educating food and drinking establishment owners and 

workers about storm water issues and BMPs. After review, the booklet could be 

kept by owners/managers for reference, and the fact sheets could be posted to 

serve as steady reminders to owners/managers and workers about storm water 

issues and BMPs. 

Storm Water Division staff coordinated with Food Establishment Wastewater 

Discharge (FEWD) Program staff for distribution of the booklet in FY 2010 to 

City-permitted facilities. The City distributed 679 booklets in the San Diego River 

Watershed Management Area (WMA). 

This activity was not included in the 2010 San Diego River WURMP because it 

does not meet the strict requirements for effectiveness assessment for 

watershed education activities; however, these posters have been distributed 

over a number of years, and the City plans to continue distribution of them. The 

booklets will continue to be distributed in the future; however, the City will not be 

reporting on this activity. 




The City will continue to coordinate with Food Establishment Wastewater 

Discharge (FEWD) Program staff for distribution of the booklet in FY 2011 to 

City-permitted facilities.

In FY 2010, the City distributed 679 booklets as referenced above in the Activity 

Implementation section. Due to the nature of this activity, although feedback on 

the booklets is generally positive, effectiveness assessment is not being 

conducted for this activity. After FY2010, the City will no longer report on the 

distribution of the booklet, and is not requesting credit as a watershed education 

activity due to the strict assessment requirements in the Municipal Permit for 

education activities.

TITLE: San Diego River Watershed Erosion and Sediment Control 

Poster 

ID NUMBER:SDR-A44 


The City of San Diego (City) printed an internally produced bilingual 

(English/Spanish) erosion and sediment control brochure and poster that are 

generally handed out to development applicants receiving a grading or public 

improvement permit from the City. The brochures and posters are also 

distributed by Storm Water Code Enforcement staff and Development Services 

inspectors when they inspect development or construction sites. The brochure is 

a tri-fold that provides information about storm water regulations, creating and 

maintaining a SWPPP and proper BMPs. The poster contains the same 

information, and is large and laminated so that it can be posted outdoors or 

indoors. The brochure and poster serve as constant reminders to construction 

managers and workers about storm water issues and Best Management 

Practices (BMPs) for construction. Photos on the brochure and poster illustrate 

erosion and sediment control measures as well as good housekeeping practices. 

In the FY 2005 Annual Report, this activity was originally reported as producing a 

flyer for distribution during pre-construction meetings; however, after further 

evaluation, City staff determined that it was best to reproduce an existing erosion 

and sediment control poster to supplement existing construction-related fact 

sheets already passed out by City staff as part of its Jurisdictional Urban Runoff 

Management Program. 

City staff coordinated internally to distribute the poster in FY 2010 to 

development applicants receiving a grading or public improvement permit from 

the City, as well as facilities that were subject to inspections. The total number of 

brochures and posters distributed in the San Diego River Watershed 

Management Area was 104. The number of posters distributed by Storm Water 

inspectors was 10 (9 in English and 1 in Spanish). 

At the current time, this activity does not meet the strict requirements for 

effectiveness assessment for watershed education activities; however, it is an 

important component of the City’s Storm Water Program and is therefore being 

included in this annual report. Furthermore, these posters have been distributed 

over a number of years with positive feedback from users, so the City plans to 

continue their distribution. The City will discontinue reporting on this activity after 

FY 2010.

PROJECT CLEAN WATER - SAN DIEGO RIVER WATERSHED 

WEBSITE 

ID NUMBER:SDR-A46 


The Project Clean Water website (http://www.projectcleanwater.org/html/ws_map.html) 

provides a venue for public participation and involvement in local watershed activities. 

The Watershed Map page is the starting point of the watershed website. Visitors 

wishing to learn more about a particular watershed can simply “click” on a desired 

watershed in the Watershed Map. Once selected, the visitor is linked to the 

watershed’s summary page and provided with additional link options. The visitor can 

view multiple informational pages on the San Diego River Watershed which include: 

• San Diego River Watershed Summary Page (main page) 

• San Diego River Watershed Plan Page 

• San Diego River Watershed Project Page 

• San Diego River Watershed Activities Page 

During the FY 2009-10 reporting period, revisions were made to update the content and 

documents available via the site, including adding reports, repairing broken links, and 

updating 303(d) listings. 


While it may be supportive of TMDL goals, this activity is not specifically implemented 

as part of a TMDL compliance program. 


This is an ongoing activity.

This method of public participation is consistent with the collective watershed strategy in 

that it encourages any member of the public to take an interest in their watershed and to 

participate in Copermittee activities. 


Activity effectiveness is not being measured directly, but can be inferred from tracking 

the number of “hits” the web pages received on an annual basis (Level 1 Outcome). 

• Watershed Copermittees continued to post the WURMP and annual 

reports on the Project Clean Water website. 

• There were 3,978 hits on the San Diego River Watershed webpage.

TITLE: 

DEVELOPMENT OF ADDITIONAL PUBLIC PARTICIPATION PROGRAMS 


During the reporting period, the City of Santee has continued to promote the opportunities 

for public participation in our stormwater program through the storm drain stenciling 

program and the Roadside Pride program. The storm drain stenciling program has 

multiple benefits including: 

• Providing stencils on storm drains reminds people in the vicinity that the drain 

provides a direct connection to the river and that their activities can have a direct 

impact on the health of the river. This reminder may result in the modification of 

their behavior to prevent the discharge of pollutants into the storm drain. 

• This program provides groups within the community an opportunity to participate in 

an activity that is related to an issue that they are interested in. This activity may 

also provide them with the necessary experience to achieve a goal related within 

the organization (such as fulfilling a community service requisite). 

• The activity may provide education for people who volunteer to help with the activity 

who may have limited knowledge of stormwater issues. This knowledge may result 

in changes to their behavior. 

The Roadside Pride Program provides Santee-based community groups with an 

opportunity to earn a small amount of money in exchange for removing litter from 

roadsides within the community. This on-going program will be promoted alongside other 

public participation opportunities. 




• Trash 

• Bacteria 


• Low Dissolved Oxygen 


This method of public participation is consistent with the collective watershed strategy in 

that it encourages any member of the public to take an interest in their watershed and to 

participate in Copermittee activities. 


During 2009-2010, the City continued to offer and raise awareness about these programs.

City of San Diego Strategic Plan for Watershed Implementation 

SDR-A48 


In spring 2006, the City of San Diego (City) initiated efforts to proactively address 

present and anticipated Total Maximum Daily Load (TMDL), Area of Special Biological 

Significance (ASBS) protection, and Municipal Storm Water Permit requirements using 

an integrated approach to maximize resources and achieve efficiencies. The result of 

these efforts was the Strategic Plan for Watershed Activity Implementation (Strategic 

Plan). Its preparation involved reviewing and assessing available monitoring and source 

data, land use data, and current and anticipated regulatory drivers. The review and 

assessment were used to prioritize the water quality problems and their sources for the 

Watershed Management Areas (WMAs) that the City has jurisdiction in and to 

geospatially prioritize the City’s portion of each of those WMAs, using best professional 

judgment, for activity implementation. 

The Strategic Plan uses an integrated, tiered, and phased approach with regards to 

activity implementation. Activities that address multiple regulations simultaneously and 

offer multiple environmental sustainability benefits are favored over those that do not 

(integration). Activities that target pollutant sources and prevent pollutant generation 

and release in the first place are emphasized and maximized before the implementation 

of more expensive structural and treatment solutions (tiering). Furthermore, the City 

pilots activities on a limited scale to measure their effectiveness and efficiency before it 

implements them on a broad scale (phasing). 

During this reporting period, the City of San Diego assisted with writing the proposed 

Senate Bill, provided financial resources for technical experts to assist with its 

development, participated in negotiations with the automobile and brake pad 

manufacturers, and provided lobbyist assistance to Senator Kehoe to obtain political 

support for the bill’s passage. Due to the automobile manufacturers renewed interest in 

this bill, negotiations were re-initiated to obtain support from all stakeholders, as 

required by the governor. The bill was rewritten multiple times and discussed by all 

parties before it was presented to Assembly subcommittees for review and approval. 

After the reporting period, SB346 was passed by both houses, signed into legislation by 

the governor on September 25, 2010, and incorporated into the California Health and 

Safety Code, Article 13.5, commencing with Section 25250.50. 

The Outdoor Water Conservation Rebate Program involved launching a city wide rebate 

program to assist residents and businesses conserve water by reducing the volume of 

irrigation and landscape runoff by incentivizing three irrigation modifications: the 

installation of irrigation smart controllers, micro-irrigation and turf conversion to low 

water use plants. Rebates are offered through a State of California grant and are 

available on a first come first served basis until funds are exhausted. Specific 

residential and commercial locations will be monitored to assess the efficiency of the 

program in reducing runoff volume and pollutant loads. Water quantity monitoring 

Page 1


(runoff volume) will be conducted both at the pre and post irrigation modification stage. 

The rebate program is scheduled to be implemented in FY11. 

In addition, the City is of the opinion that the integration of storm water and urban runoff 

pollution management with other environmental efforts and infrastructure improvements 

is crucial for achieving efficiencies and cost savings in a period of seemingly perpetual 

municipal budget deficits. This integration is also crucial for obtaining the public’s 

support of storm water and urban runoff pollution management efforts. 

Development of the Strategic Plan included the formulation of a list of activities to 

implement during Phase I. These activities have been integrated into the various 

Watershed Urban Runoff Management Programs (WURMPs) that the City implements 

in conjunction with other local jurisdictions. Each fiscal year, the City updates its list of 

activities to reflect new data, schedule changes, and staffing and budgetary 

considerations. Many of these activities are reported as watershed water quality and 

education activities in the various WURMPs. However, the City has a list of project 

types and sources it plans to implement/target with no specific information. Because 

these are so conceptual in nature, the City does not report on them as specific activities. 

Those that are concepts not yet into development but planned for initiation within the 

next few years are listed in the table below.

information to help prioritize the water quality problems, pollutant sources, and areas of 

the City to target for activity implementation. 


Each activity has its own specific implementation schedule. However, implementation of 

Phase I of the Strategic Plan (the piloting stage before implementation on a broader 

scale) is anticipated to occur from FY 2008 through FY 2013.

All Water Quality Problems are addressed as the goal of the Strategic Plan is to 

address multiple problems simultaneously as feasible to achieve efficiencies 


Subsequent to the adoption of the Municipal Storm Water Permit (Order No. R9-2007- 

0001) in January 2007, the Copermittees developed a Model Watershed Strategy to 

help guide their planning, implementation, and assessment efforts in the various WMAs. 

The Model Watershed Strategy assists the Copermittees in developing a Collective 

Watershed Strategy for each WMA. Application of the Model Watershed Strategy 

results in prioritizing areas within each WMA for activity implementation; selecting and 

prioritizing appropriate watershed activities, including monitoring and pollutant source 

identification studies, for each of the prioritized areas; and identifying data gaps with 

regards to monitoring and pollutant sources, which need to be filled to enable more 

refined future management decisions. 

Although developed independently of each other, the City’s Strategic Plan and the 

Copermittees’ Model Watershed Strategy share the approach of reviewing the best 

available data (e.g., water quality and pollutant source data) and analyzing them 

geospatially to make management decisions regarding: (1) water quality problems to 

target and activities to implement; and (2) geospatial prioritization of the WMAs for 

focused activity implementation. 

Note that the Strategic Plan is primarily an activity implementation approach. However, 

the conclusions that it makes regarding priority water quality problems are in harmony 

with the conclusions made in Section 3, Water Quality Assessment, of this WURMP 

Annual Report. 

Page 5




CITY OF SAN DIEGO STRATEGIC PLAN IMPLEMENTATION 

Each activity will be assessed independently, and programmatic assessment will occur 

annually in Section 4 of the WURMP annual report. 

Assessment of the Strategic Plan is a long-term effort and will involve tracking the City’s 

progress on piloting activities over the next five years to be able to make conclusions on 

how to optimize the efficiency of its storm water program to meet water quality goals 

and regulations.

TITLE: 

Receiving Water Monitoring for Priority Pollutants in the San Diego 

River Watershed 


The City of Santee has conducted an additional study each year since 2002 to assess 

constituents of concern at five receiving water locations within the watershed. These 

locations include Forester Creek as it enters the City of Santee and prior to its confluence 

with the San Diego River (two locations); the San Diego River as it enters the City of 

Santee; Sycamore Creek as it discharges into the San Diego River; and the San Diego 

River just as it leaves the City of Santee (three locations). These locations are typically 

sampled twice during the dry season, at the beginning and towards the end of the dry 

season. This investigation was reviewed during Fiscal Year 2007 and revised to 

incorporate the constituents listed on the 303(d) list for the Forester Creek and San Diego 

River. 




• Bacteria 


• Dissolved Oxygen 

• Phosphorous 


The dry weather monitoring program focuses on potential pollutants within the MS4. 

Monitoring receiving waters within the City helps to evaluate water quality within City limits. 

The data can be incorporated with data collected within other jurisdictions to develop a 

profile of water quality within the watershed. This helps to identify areas where loadings of 

priority pollutants may be increasing and to assist in developing watershed activities in 

appropriate locations that may result in water quality improvements. This activity is 

consistent with WURMP Strategic Goal 5 for Bacteria Source Reduction. 


Developed a QAPP for the additional monitoring program and conducted two additional 

rounds of monitoring.

Municipal Park Irrigation Runoff Minimization 

SDR-A50 


This activity consisted of municipal park facility inspections to assess the 

potential urban runoff and pollutant reduction measures at selected municipal 

parks within the San Diego River Watershed Management Area (WMA). The 

City of San Diego participated in this activity, which is part of a collaborative 

watershed effort initiated by the San Diego River Watershed Workgroup. This 

activity also fostered dialogue with the Parks and Recreation Department staff on 

how to reduce dry weather runoff and pollutant exposures at parks. 

The parks selected for this inspection activity were in collaboration with the Park 

& Recreation Department and the Storm Water Department. The four parks 

selected for this inspection activity were Ocean Beach Athletic Area Robb Field, 

Robb Field Recreation Center, and Robb Field Skate Park; Dusty Rhodes Park; 

Serra Mesa Community Park and Recreation Center; and Tierrasanta 

Community Park and Recreation Center. Two parks are located in the coastal 

area and two parks are located in the inland area. 

The project implemented an inspection checklist, developed specifically for 

parks, as utilized by the other San Diego River Copermittees. The parks were 

inspected twice. A baseline inspection was performed during the day to collect 

information regarding the parks, identify potential evidence of runoff, and identify 

potential pollutant sources. The second inspection was conducted during 

irrigation system operations, generally conducted overnight, to identify pollutant 

exposure or evidence of dry weather runoff. A summary of the findings is 

presented in the Effectiveness Assessment section below. 




This activity was completed by the City of San Diego during FY 2009-2010. This 

activity was previously completed by other jurisdictions in FY 2008-09. There is

Assess the Efficiency and Effectiveness of Municipal Park Irrigation Runoff Minimization 



Outcome(s) 


Data Recorded 

Municipal Parks - San Diego River WMA 

1) What are the physical characteristics of municipal parks which contribute 

to over-irrigation and urban runoff? 

2) What patterns or applications of water that may impact water quality can 

be identified at municipal parks? 

3) What are the procedures and maintenance practices which contribute to 

over-irrigation and urban runoff at municipal parks? 

• Reduction in pollutant load 


• Inspections 

• Quantification 

• Monitoring (e.g., average over-irrigation flows) 

• Reporting (e.g. identify pollution sources) 

Number of inspections (Outcome Level 1) 8 

Number of distributed education materials (Outcome Level 1) 25 

Objectives 

The goal of this inspection assessment was to determine the potential for 

pollutant discharges and dry weather runoff at municipal parks, particularly from 

irrigation systems. 


Potential sources for pollution and runoff found were picnic areas, dumpsters, offsite 

water entering the municipal parks, and automobile maintenance in the 

parking lot by the public. 

Based upon the inspection during the irrigation cycle operation at the four 

municipal parks, most irrigation water is delivered to vegetated areas as intended 

and relatively minor levels of irrigation water runoff reached the storm drains. 

There were three types of potential sources of runoff: sprinkler overspray onto 

Page 2


impervious surfaces; irrigation system operation leading to flow onto impervious 

surfaces; and off-site irrigation entering the municipal park boundary. Irrigation 

runoff can also be attributed to the topographical characteristics of the park. 

Conclusions 

Based on the results, the parks were generally well maintained. The observed 

irrigation runoff is considered to be relatively minimal. The Park and Recreation 

Department utilizes a Best Management Practices Manual and storm water 

issues are generally well considered. For the minor issues that were identified, 

follow-up communication was provided to Parks and Recreation Department to 

encourage the staff to address not only these incidents, but to manage potential 

over-irrigation and pollutant exposure issues on an ongoing basis. This activity 

fostered communication between Storm Water Department and Park and 

Recreation Department on how to reduce dry weather runoff and pollutant 

exposures at parks. Educational materials were distributed to the Park & 

Recreation staff. This activity also raised storm water awareness and increased 

knowledge to the Park and Recreation Department. The reporting of this activity 

will end with this annual report.

Qualcomm Stadium Trash Segregation Best 

Management Practice (BMP) Installation 

SDR-A52 


This project will involve the installation of catch basin inserts at two catch basins 

at Qualcomm Stadium. The catch basin inserts would be installed directly in the 

existing curb inlets. The Qualcomm Stadium site location will include the 

implementation of storm drain catch basin inserts as retrofits within the existing 

storm drain system. 

The City of San Diego (City) will study the effectiveness (in terms of load 

reduction) and the efficiency (in terms of load reduction divided by cost) of such 

devices in improving discharge and water quality. 


• None 


This project is part of a Storm Drain Inlet Inserts Pilot Project. The City of San 

Diego issued a Request for Proposals (RFP) from interested vendors and 

advertised the project as a pilot at no cost to the City. Interested vendors 

submitted their proposals in July 2010 and the City conducted a selection 

process to evaluate the submitted proposal. Based on the selection panel 

recommendation, vendor product(s) that met the performance standards and 

requirements of the RFP have been awarded. The catch basin inlets will be 

retrofitted with the selected drainage inserts within the next month or so and the 

first phase of monitoring will begin immediately after installation.

Robb Field Water Treatment and Reuse Project 

SDR-A53 


This project will construct a storm runoff collection and treatment facility at the 

northwest corner of Robb Field, a Park & Recreation Facility. Once treated, the 

storm water will be stored and used to irrigate the adjacent 14 acre grass athletic 

field. The City has named this model approach for Low Impact Development 

(LID) in commercial and industrial areas as “Storm Water Reuse” and, if proven 

to be effective, anticipates eventually implementing similar LID projects. 




Project planning began in June 2009. The work performed in FY 2009 included 

the conceptual design and the City facility stakeholder, Park and Recreation 

Department (PRD). The City of San Diego is currently assessing our options for 

implementing this project. Water quality monitoring is anticipated be conducted 

before and after construction to assess the effectiveness in reducing runoff 

volume and pollutant loading.

San Diego River Watershed Brochure 

SDR-A54 


In FY 2010, the City of San Diego (City) and Think Blue implemented a new 

brochure program in two (2) of the watershed management areas (WMAs) 

assigned to the City. These brochures will be used to inform San Diego 

residents on the benefits of taking steps to reclaim an environmentally and 

economically healthy watershed. The education pieces will help address high 

priority water quality problems in each WMA. The brochures will also be used to 

promote watershed stewardship by making citizens aware of specific pollutants 

within each watershed, and ways individual action can be used to protect each 

water body. It will also be used to make citizens aware of specific pollutants and 

ways individual action can be used to protect each water source as a way to 

promote watershed stewardship (all individual actions within each watershed 

adds up in a cumulative way to influence the health of the water resource). 

The main goals of the brochures are to improve the public’s understanding of 

basic watershed principals, address the high priority water quality problems in 

each WMA, educate about best management practices (BMPs), and encourage 

citizens to take positive steps in preventing pollution from entering the storm 

drain system. 

The following WMAs had watershed specific brochures created: 

• Tijuana River 

• San Diego River 


Brochures will target pollutants associated with TMDLs as applicable. 


Project planning began in FY 2009 and continued through FY 2010. 

Implementation and initial distribution occurred in late FY 2010.

• Bacteria 


• Turbidity 



This activity will address the high priority water quality problems identified in both 

the City’s Strategic Plan for Watershed Activity Implementation and the Collective 

Watershed Strategy for the Watershed Management Areas. 


Objectives 

Effectiveness Assessment will take place in FY2011. The goal of assessment will 

be to determine the effectiveness of the watershed brochure in increasing 

knowledge and awareness, and whether the brochure will encourage positive 

behavioral changes that will reduce bacteria and gross pollutants in the 

watershed. The City is planning a feedback assessment activity which will 

include gathering feedback from target audiences via a feedback card. The card 

will be available at the Think Blue booth during various community events that 

take place in or near the watershed. Event attendees would be randomly 

selected to either receive or not receive the brochure, then asked to complete a 

response card. Within 3 months, those that provided contact information will be 

contacted and asked a series of follow-up questions to determine if the brochure 

has a lasting impact. 


An effectiveness assessment of this activity is not possible at this time because 

the watershed brochure has not yet been distributed. 

Conclusions 

The City plans to continue to implement the brochure program in FY 2010. 

Effectiveness assessments will be conducted after the watershed brochures are 

implemented in FY 2010. This activity will be used as a watershed education 

activity as required by the Municipal Permit for education activities.

TITLE: Stormwater Quality Master Plans for Special Drainage Fee Areas 



The County of San Diego is in the process of preparing Storm Water Quality Master 

Plans (SWQMPs) for ten Special Drainage Fee Areas (SDAs). The SWQMPs address 

water quality impacts within each area, and are being prepared concurrently with a GISbased 

Drainage Facilities Master Plan (DFMP). The County has identified a need to 

replace or upgrade portions of the drainage systems within its SDAs to meet current 

drainage design standards. In the process of planning for the proposed drainage facility 

improvements, the County is seizing the opportunity to identify potential regional BMPs 

that would assist in improving watershed water quality and minimize associated 

drainage facility maintenance costs. 

Ultimately, the SWQMPs will identify and prioritize for implementation a list of potential 

regional BMPs. BMPs could include extended detention basins, hydrodynamic 

separators, or other BMP types. Prioritization criteria will include considerations of cost, 

BMP type, location, land use, and funding. Construction of recommended BMPs is 

contingent upon the approval of SDA fee increases by the County Board of Supervisors. 

SWQMPs with the potential to propose BMPs in the San Diego River Watershed 

include: 

• SDA 5 (Bostonia) 

• SDA 6 (Lakeside) 

• SDA 7 (Alpine) 

FY 2009-10 ACTIVITY IMPLEMENTATION 

The SWQMPs for SDA 5, SDA 6, and SDA 7 are in draft form and undergoing review by 

County personnel. 




Review and adoption of the Storm Water Quality Master Plan is expected to take place 

in FY 2011-12. Construction of BMPs is contingent upon approval of SDA fee increases 

Page 1


by the County Board of Supervisors. If adopted, the Board is likely to consider fee 

increases in 2013.

EXPECTED BENEFITS 

The SWQMPs will recommend regional structures or devices intended to improve 

watershed water quality. Regional BMPs address large mixed-use watershed areas, 

rather than smaller watersheds from individual development projects.

Pet Waste Management Outreach 

SDR-A56 


This activity targets potential, new, and existing pet owners and seeks to educate them 

on the importance of cleaning up after their pets, as well as tying a water quality and 

watershed protection message into the outreach activity. A presentation was developed 

that included a pre- and post-presentation survey asking participants about their pet 

waste management practices. Between the pre- and postsurveys, participants will 

review a series of slides that define a watershed, a general description of the MS4 

system, the link between bacteria and water quality, and the importance of cleaning up 

after their pets. The presentation will also include tips for managing pet waste properly 

and encouraging participants to clean up after their pets each and every time. 

Each jurisdiction will select at least two local pet-related businesses, selecting from pet 

day-care facilities, pet food retail stores, adoption centers, and/or veterinary clinics to 

present the materials. 


During FY 2009-10 the pet waste survey and training were finalized and used at a 

number of events. 

San Diego RiverFest – All Jurisdictions Participated 

The San Diego River Watershed Copermittees participated in the first Annual San 

Diego RiverFest. The San Diego River Park Foundation held the Annual RiverFest 

event at the Qualcomm practice field. The event drew a large number of participants; it 

was initially estimated at approximately 5,000. Copermittees had an outreach booth at 

the event with educational materials targeting existing pet owners. The materials 

consisted of a presentation that included pre- and post-presentation surveys asking 

participants about their pet waste management practices. Between the pre- and postsurveys, 

participants reviewed a series of slides that defined a watershed, a general 

description of the storm drain system, the link between bacteria and water quality, and 

the importance of cleaning up after their pets. The presentation also included tips for 

properly manage pet waste and encourage participants to clean up after their pets each 

and every time. 

The booth had representation from every Copermitte in the San Diego River Watershed. 

Every participant that reviewed the presentation and took both surveys received a bag 

that included a pet waste bag dispenser. Every person that stopped by the booth 

received informational materials about water quality and watersheds. 

Page 1



The City of El Cajon held an educational booth at the City’s Dog Park. The Dog Park 

has a good influx of dog owners that attend the park throughout the day and provides a 

good opportunity for outreach. The booth offered educational materials to everyone 

who stopped by the booth, and giveaways only to pet owners that took the surveys and 

reviewed the presentation. A multitude of pet owners approached the booth and 

received informational materials but only a fraction participated in the presentation and 

surveys. A total of fourteen pet owners took the pre and post presentation surveys. 


The City of La Mesa targeted to educate potential, new, and existing pet owners with 

presentations about pet waste management practices. The presentations were 

conducted at the San Diego River Park Days event on May 16, 2010; and at the Creek 

to Bay Clean Up event on April 24, 2010. 

In addition, this activity seeks to educate them on the importance of cleaning up after 

pets, as well as tying a water quality and watershed protection message into the 

outreach activity. Between the pre- and postsurveys, participants reviewed a series of 

slides that define a watershed, a general description of the MS4 system, the link 

between bacteria and water quality, and the importance of cleaning up after their pets. 

The San Diego River Park Days event was a collaboration between the Cities of San 

Diego, La Mesa, El Cajon, Santee, and the County of San Diego. 

City of Santee 

The City of Santee contacted Petco, a pet store in Santee that does training sessions 

for new owners. City staff arranged with the manager at Petco to present the pet waste 

information at new owner training. Dates when this was done are presented below: 

April 29 th , 2010 – City staff attended scheduled training, however no pet owners were 

present to receive the training. 

May 27 th , 2010 – Two pet owners attended and received training on pet waste 

management from City staff. 

Petco has a fair once a year in the Spring where different organizations have booths. A 

larger number of individuals attend this event and would provide a more cost effective 

way to reach out to more residents in Santee. The City will explore using this event as 

a venue to conduct outreach. Based on a review of the City’s business inventory there 

are no doggie daycare facilities. However the City will continue to find ways to reach 

out to residents through pet stores and animal hospitals within the City, as well as 

through community events. 

City of San Diego 

On Sunday May 23 rd , Think Blue staff set up a booth at the OB Dog Wash in Ocean 

Beach to educate dog owners about proper disposal of pet waste. Patrons were asked 

to take a short pre-test to determine their knowledge of the proper disposal of pet waste 

Page 2


and the impact bacteria from pet waste can have on local waterways. Patrons were 

then encouraged to review a brief flip book presentation entitled, “The Scoop On Dog 

Poop” which provided educational information about bacteria in found in pet waste, its 

potential impact on watersheds and methods of proper pet waste disposal. After 

reviewing the material, patrons were given a post test to determine if their knowledge of 

pet waste had increased. In exchange for their time patrons were given an pet theme 

related incentive item (e.g. collapsible dog bowl) for participating. Think Blue staff 

collected 19 surveys. 

On June 5 th , Think Blue staff set up a booth at the San Diego Chapter of the Bassett 

Hound Rescue Annual Picnic held at the Allied Gardens Community Park. Patrons 

were asked to take a short pre-test to determine their knowledge of the proper disposal 

of pet waste and the impact bacteria from pet waste can have on local waterways. 

Patrons were then encouraged to review a brief flip book presentation entitled, “The 

Scoop On Dog Poop” which provided educational information about bacteria in found in 

pet waste, its potential impact on watersheds and methods of proper pet waste 

disposal. After reviewing the material, patrons were given a post test to determine if 

their knowledge of pet waste had increased. In exchange for their time patrons were 

given an pet theme related incentive item (e.g. collapsible dog bowl) for participating. 

Think Blue staff collected 23 surveys. 


On September 26, 2010, the Lakeside Fire Department held its annual Open House, 

and invited various participants including the County’s Storm Water Protection Program 

to set up a booth to share materials. The Cities of Santee and El Cajon also participated 

in this event. The pet waste presentation and pre- and postsurveys were provided at 

the County’s booth. A total of 39 total surveys were handed out to participants, and 31 

pre- and postsurveys were completed. Eight surveys were discarded, as the 

participants did not complete the presentation or postsurvey. 

The county is planning at least one additional activity during FY10-11 to complete its 

goal of achieving two presentations made. 


Bacteria is listed on the 2008 303(d) list in the San Diego River Watershed. As such, 

this activity has potential to support future TMDL implementation. 


Completing the presentation materials and survey, identifying the businesses to target 

and executing the outreach activity occurred during FY 2009-10. 

• Completed presentation materials – 2009 

Page 3


• Identified businesses to target – 2009 

• Commence delivering presentations – 2010 

• Plan to complete presentations during FY10-11 








• None 


• Bacteria 


Bacteria have been identified as priority water quality problems in the San Diego River 

Watershed. Pet waste in particular is a potential source of bacteria. Since this activity 

addresses a priority water quality problem and a priority source, it is consistent with the 

collective watershed strategy. 


Ten pet waste management presentations were targeted for FY 2009-10 (Level 1 

Outcome). The increased scores in the post-presentation survey show an increase in 

knowledge and awareness (Level 2 Outcome), and hopefully a change in future 

behavior (Level 3 Outcome). 


The results of the survey showed an increased level of knowledge between the pre and 

post presentation surveys. The averaged percentage of correct answers for the pre 

presentation survey was 76% compared to 83% for the post presentation surveys. 

There was a 7% average increase in the number of correct answers (Level 2 Outcome). 

The increase in the number of correct answers to the survey demonstrated that the 

information in the presentation help to show pet owners the importance of picking up 

after their pets and presumably a change in behavior (Level 3 Outcome). 

Page 4



At the Creek to Bay Clean up event in April, 12 persons were given the presentation 

with a pre-test survey correct percentage of 75%, and a post survey correct percentage 

of 83% (Level 2 Outcome). 


Results are calculated by comparing total correct answers from the pre- and postsurveys, 

and determining the average percentage difference between the two. A 

positive percentage shows an increase in knowledge between the pre- and postsurvey. 

Of the 31 surveys completed at this event, the overall result was a 28 % 

increase in knowledge between the pre- and postsurveys, Pre- survey correct answers 

totaled 101 and post-survey correct answers totaled 140. Out of 31 surveys, 11 

participants were able to correctly identify the watershed they live within, and 23 

participants signed the “Personal Pledge” to pick up after their pets regularly. Therefore 

it can be concluded that for two-thirds of the surveys collected, we were able to reach 

Levels one, two and three outcomes.

San Diego River Invasive Species Removal 

SDR-A57 


The County of San Diego Department of Public Works has been working in coordination 

with the San Diego River Conservancy to remove Arundo donax and other non-native 

species along the San Diego River. The removal is occurring on a 1.78 acre Countyowned 

parcel located in the City of Santee (APN 383-060-25-00). Arundo and nonnative 

palms were removed during October 2009 by the California Conservation Corps. 

Cut vegetation was chipped and taken to the landfill and stumps were treated with 

herbicide to prevent regrowth. 

This site will be planted with native riparian vegetation to match surrounding habitat, 

including southern willow scrub/cottonwood willow riparian vegetation at some point in 

the future, but currently is pending discussions with the local resource agencies as to 

when that will begin. Maintenance and monitoring of the newly planted vegetation will 

be performed by the County until success criteria is met, which is estimated to be within 

3 to 5 years of planting. No water quality monitoring related to this specific project has 

been planned. 


• Planning and coordination for the activity began March 1, 2009. 

• The invasive removal program was begun in October 2009. 




• Follow-up herbicide treatment is scheduled for November 2010. 

• The non-natives will be cut and removed from the site after the material dies off in 

early 2011. 

• Herbicide treatment will be conducted if necessary in May and September of 2011, 

to retreat any additional regrowth. Monitoring and maintenance of site vegetation – 

3-5 years after planting, until successful growth occurs.

• All 

EXPECTED BENEFITS 

This Invasive Species Removal project will not only enhance water quality and aid in 

flood control measures, but will help the County realize 1.56 acres of wetland credits to 

be used as mitigation for RPG 53 projects (related to invasive species removal in river 

bank areas). 


Removal of invasive species benefits water quality by restoring the river’s natural 

condition and native vegetation. Native vegetation provides greater filteration and 

treatment of pollutants. As such, this water quality activity is consistent with the 

collective watershed strategy, which seeks to abate pollutants in the watershed. 


Activity effectiveness will be measured by ensuring completion of all project elements 

(Level 1). Re-planted areas will be monitored and maintained to ensure the invasive 

species do not re-grow and native riparian vegetation is successful.

TITLE: San Diego River Park Foundation County Sponsored Clean Up Event in 

Santee 



San Diego River Park Foundation with the sponsorship of the County of San Diego 

organized and performed a volunteer clean-up effort with approximately 100 volunteers 

to remove garbage, debris and abandoned encampments as part of a community 

cleanup on the County-owned property within the San Diego River Corridor. SDRPF 

staff and volunteers identified a site on COSD property within the city of Santee along 

the San Diego River that would benefit from a trash and debris removal event. 

The 79 acre parcel of property located within the San Diego River corridor on Countyowned 

Edgemoor property in the City of Santee (APN 381-050-62-00). Staging 

occurred at the parking area at Cottonwood Avenue and Chubb Lane (see photo). 

Volunteers of the San Diego River Park Foundation identified trash and debris equating 

to 5000 lbs. and over 100 bags of trash on site. 

For the County’s sponsorship, the San Diego River Park Foundation provided: 

• Event logistics and necessary supplies including tools, safety equipment and trash 

bags. 

• Water and food for volunteers. 

• Facilitation of dumpster delivery and placement/removal, including hazardous / 

alternative waste disposal. 

• Use of SDRPF vehicle. 

A City of Santee representative also attended this event.

Event Date and Time: February 20, 2010 9am-Noon 




No further activity is planned during this fiscal year. 







• Trash 

• Bacteria 


Bacteria indicators and trash have been identified as priority water quality problems in 

the San Diego River Watershed. This activity demonstrates a reduced pollutant load of 

trash and associated bacteria, which benefits the receiving water quality. Since this 

activity addresses priority water quality problems it is consistent with the collective 

watershed strategy. 


Activity effectiveness is to be measured by assessing the amount of trash and debris 

removed from the site (Level 4 Outcome). An estimated 5,000 lbs of trash and debris, 

apparently from illegal dumping, were removed from the site, including 8 tires, 2 car 

batteries, one T.V. and construction debris identified at the site.

TITLE: WATER QUALITY MONITORING IN THE UNINCORPORATED AREAS OF 

THE SAN DIEGO RIVER 



The County of San Diego performed water quality monitoring in the San Diego River 

Watershed during two wet weather events and one dry weather event at three 

monitoring stations. The monitoring was conducted from February 2009 through 

December 2009. The purpose of this monitoring was to collect additional data regarding 

concentrations and loading of bacteria in the unincorporated portion of the watershed. A 

secondary goal was to provide data to the San Diego River Watershed Workgroup 

during a similar effort being conducted within the watershed coordinated by the City of 

San Diego. The monitoring included flow rate and constituent loading and flux 

measurements during the wet weather and one dry weather runoff events. 

Wet weather monitoring was conducted over two storm events at three sampling 

locations. A total of six grab samples were collected at each site per storm over a 

pollutograph and tested for chemical constituents. Grab samples were also collected 

for microbiological analysis. During storms, bacterial samples were collected over a 

pollutograph. Estimates of continuous flow at each site were made using Sigma 950 

Flowmeter with a pressure/level transducer. Data from the USGS gauging station at Los 

Coches Road (COSDSDR08) was used to validate the flow measurements collected. 

Grab samples were collected for all microbiology samples using PCR trained, clean 

hands techniques. Bacteria analysis was conducted for total coliform, fecal coliform, 

enterococcus and the presence/absence of human fecal contamination (Bacteroides 

fragilis). 

Sample site locations include: 

• SDR07 San Diego River @ Upper Forester Creek Tributary 

• SDR08 Los Coches Creek @ I-8 Business Route 

• SDR10 San Diego River @ Riverford Road 

A fourth site (SDR28) was considered but was not monitored as it had no flow during 

the study’s time period. 


• During FY 2008-09, monitoring was conducted during one wet and one dry weather 

event at three monitoring stations. Water quality data are presented in tabular format in 

the attached report. 

• During FY 2009-10, monitoring was conducted during one wet weather event at three 

monitoring stations. Data analysis was completed in December 2010.

• Monitored one additional wet weather event – FY 2009-10 

• Completed data analysis and final report – FY 2009-10 




• None 


• Bacteria 


Bacteria have been identified as a high priority water quality problem in the San Diego 

River Watershed. Since this activity is focused on identifying and abating sources of 

bacteria, it is consistent with the collective watershed strategy. 


Activity effectiveness is measured by ensuring completion of all water quality monitoring 

for this project (Level 1). The final study was published December 2010. The study 

provided needed baseline water quality data for the portions of the lower San Diego 

River watershed located within the County of San Diego jurisdiction. Three sampling 

locations were monitored, each exhibiting unique drainage area characteristics: 

• COSDSDR10 was generally ponded with a wide a flood plain and relatively low 

flow velocities, even during storm events. 

• COSDSRD08 had a narrow channel with steep sides that was influenced by 

continuous dry weather flows and relatively high flow velocities during storm 

events. 

• COSDSDR07 had flow only during storm events; its channel was narrow and 

composed of very coarse sand. 

With respect to water quality monitoring, the results of the present study can be 

summarized as follows: 

• Total nitrogen and total phosphorus concentrations generally exceeded Basin 

Plan water quality objectives (WQOs) of 1 mg/L and 0.1 mg/L respectively at all 

sampling locations in storm water flows. During non storm conditions, total 

nitrogen WQO was exceeded at both locations sampled and total phosphorus 

WQO was exceeded at one of the two. 

Page 2


• Total phosphorus and TSS concentrations increased with increased flows from 

storm water runoff at all locations monitored. The tendency of phosphorus to 

bind to sediment particles may explain these correlated increases in the 

concentrations of TSS and total phosphorus. 

• The 24-hour dry weather loads were very similar at both sampling locations 

(COSDSDR08 and COSDSDR10) for all chemical and microbiological 

constituents monitored. 

• Wet weather loads were orders of magnitude higher at COSDSDR10 than at 

COSDSDR08 during the February storm for all chemical constituents except 

TSS; bacterial loads were also higher at COSDSDR10. 

• During the December storm, organic nitrogen, TKN, total nitrogen, total 

phosphorus and E. coli loads were higher at CPSDSDR08. Notably, TSS loads 

were three times higher at CPSDSDR08 during December storm while they were 

only slightly higher at that location during the much less intense February storm. 

As phosphorus, organic nitrogen, and bacteria may be bound to sediment, this 

would likely provide some rationale for this difference. 

• Total nitrogen and total phosphorus flux (in kg/acre) increased with rainfall 

amount and intensity. 

• Non storm dissolved oxygen concentrations met Basin Plan WQOs at 

COSDSDR08 and COSDSDR10. 

• TDS concentrations exceeded the 1000 mg/L Basin Plan WQO during non-storm 

conditions at both locations monitored; during storms, TDS concentrations 

decreased and increased upon return to baseflow as supported by continuous 

conductivity results. 

• Bacteria concentrations generally exceeded WQOs but Bacteroides testing 

results were not indicative of recent human fecal sources. 

• Although bacterial loads were higher during wet weather than in non-storm flows, 

bacteria flux (loads per acre) values during storms and non-storm conditions did 

not differ significantly among the monitored drainage areas.

Municipal Park Inspections 

SDR-A60 


This project consisted of inspections of municipal park facilities by stormwater program 

staff using inspection checklists developed specifically for parks, and then addressing 

identified issues. The San Diego River Copermittees modeled the checklists after other 

successful forms, including forms used in previous Source Identification Studies. With 

the guidance of the forms, inspectors visited a number of parks within the watershed to 

assess the potential for pollutant exposures and for dry weather runoff, particularly from 

irrigation systems. Based on these inspections, Stormwater Department staff worked to 

develop stronger relationships and better communication with Parks and Recreation 

Department staff. The purpose of this activity was not only to address the specific 

incidents and issues identified at the parks visited, but to foster dialogue with Parks and 

Recreation Department staff on how to reduce dry weather runoff and pollutant 

exposures at parks. 

ACTIVITY IMPLEMENTATION FY 2009-10 


In FY 2009-2010, annual municipal facility inspections were conducted with all three 

parks which were included in the fiscal year 2008-2009 activity. The results of the 

2009-2010 inspections yielded positive results based on the previous year’s work. The 

only park which had corrective actions was Northmont Park, which has some dirt and 

debris within a storm drain inlet which needed cleaning. Jackson and La Mesita Park 

did not have any corrective actions. 




This activity was completed for four jurisdictions in fiscal year 2008-09, but is being 

reported again to show follow up inspection results for the City of La Mesa for fiscal year 

2009-10.

No outside entities participated in this activity, but the Stormwater Departments for each 

Copermittee worked closely with their respective Parks and Recreation Departments 

when implementing this activity. 


• Trash 

• Nutrients 

• Bacteria (indirectly through trash) 


The activity is consistent with the collective watershed strategy because it addresses 

several Strategic Goals established by the WURMP, including Goal 1 for Dry Weather 

Flow Reduction, Goal 2 for Municipal/Park Source Reduction and Goal 5 for Bacteria 

Source Reduction. The activity addresses pollutant load reductions, source abatement, 

and pollutant transport mechanisms, and may have other quantifiable benefits to 

discharge or receiving water quality in relation to the watershed’s high priority water 

quality problem(s). 


Activity effectiveness was measured by confirming completion of all project elements 

(Level 1 Outcome), by measuring changes in knowledge and attitude (Level 2 Outcome) 

using surveys and by confirming reduced or no runoff water from the site (Level 4 

Outcome) during follow up inspections. The City of La Mesa did incorporate sampling of 

observed irrigation runoff into its inspection program, but no other water quality 

monitoring was planned for this activity.

TITLE: 

Irrigation Runoff Reduction 


The City of Santee is conducting a pilot project experimenting with the removal of existing 

median vegetation with high water needs and the planting of drought tolerant vegetation 

instead. This pilot study will be conducted on four median strips in Mission Gorge Road 

within the City. The City will also be conducting a study to assess the cost and costeffectiveness 

of extending this approach throughout City maintained landscape 

maintenance districts. The City has hired a consultant to advise it on the technical issue of 

which plants to use, and another consultant to assist with evaluating the economics of the 

project. The goals of the project are both to eliminate the overuse of water and to reduce 

runoff. 




• TDS 

• Bacteria (Indirect – Elimination of Transport Mechanism) 

• Nutrients – Phosphorus (Indirect – Elimination of Transport Mechanism) 

• Gross Pollutants (Indirect – Elimination of Transport Mechanism) 

• Turbidity (Indirect – Elimination of Transport Mechanism) 



Strategic Goals 1 and 2 for Dry Weather Flow Reduction and Municipal/Park Source 

Reduction of high priority pollutants. Since overirrigation runoff is a primary mechanism for 

dry weather flows and dry weather flows serve as a transport mechanism for many 

watershed priority pollutants, this project will help to reduce both flow and pollutant loading 

in the watershed. 

TASKS IMPLEMENTED DURING FY 2010-2011 

The City has commenced project design and anticipates implementation to start during FY 

2010-2011.



TITLE: 

Commercial BMP Self Certification Pilot Project 


This program includes an assessment of urban runoff from a major, mixed use parking lot 

in La Mesa (super market with additional shops). The load contribution of the parking will 

also be examined. The project also includes an education and outreach component in 

order to open dialogue with property management. The shopping center management will 

provide source control BMP maintenance records for the City to assess. 

Recommendations will be made to property management, and self certifications will be 

required annually. Additional wet weather samples will be collected for assessment. The 

City may decide to continue the program for different commercial centers within the 

watershed.

Think Blue sponsored the purchase of 100 new trash bins for Qualcomm Stadium. The 

new trash bins are 3-cubic yard metal bins with lids. The new trash bins are distributed 

throughout the 150 acre parking lot at Qualcomm Stadium. These trash bins replaced 

the stadiums old lidless trash bins. The trash cans are designed to provide stadium 

attendees with additional infrastructure with which to properly dispose of trash that is 

generated. Additionally, the increased size of the bins allows for additional trash to be 

collected while the lids prevent trash, and the resulting bacteria, from blowing into the 

San Diego River.

Pet Waste Bag Dispenser Program 

SDR-A69 


This activity will target areas frequented by pet owners such as apartment 

complexes, condominiums, mixed-use locations, and public right of way in the 

San Diego River Watershed Management Area (WMA). When pet waste bags 

are available, pet owners are more apt to pick up pet wastes and dispose of it 

properly, thereby eliminating pollutants from the environment and potentially from 

receiving waters. Pet waste bag dispensers will be installed in areas lacking 

them or in need of additional ones. 

This project was in its planning stage during FY 2010. Watershed maps were 

developed and utilized to assist in the selection of potential installation locations. 

Criteria used were: 

a) Canine related activity, e.g. dogs being walked 

b) Cleanliness (observed pet waste) 

c) Presence of trash receptacles 

d) Presence of pet waste bag dispensers 

e) Areas draining to a water body impaired for bacteria, phosphorus or nitrogen 

f) Potential for Partnership 

g) Areas of Complaints/Chronic Pet Waste Observations 

Three watershed management areas (WMAs) were selected for implementation 

in FY 2011: Mission Bay and La Jolla, San Diego Bay, and San Diego River.

Focused Outreach to the Equestrian Community 


The County of San Diego conducts focused water quality outreach and education to the 

equestrian community and other owners of small animals and livestock in the 

unincorporated area. Education focuses on BMPs of importance to this community, 

including manure management, composting, and erosion control. Activities include, but 

are not limited to: workshops, booths at community events, development and 

distribution of educational materials, surveys, and partnerships with equestrian 

community groups. 

ACTIVITY IMPLEMENTATION FY09-10 

Workshops 

During FY09-10, the County of San Diego, in coordination with the Solana Center for 

Environmental Innovation (Solana Center) and the Mission Resource Conservation 

District (MRCD), conducted workshops targeting equestrians to provide training on a 

variety of topics including: 

• Manure management and composting basics 

• Prevention of odors and flies 

• Benefits of composting 

• Application of compost to gardens and landscapes 

• Land use regulations 

• Protection of local water sources. 

Workshops during FY09-10 were held in Bonita, Lakeside, Ramona, and Fallbrook. The 

table below identifies the primary watershed(s) addressed by each workshop.

Bonita 6/28/10 25 Sweetwater 

Total 113 

Funded by the County, the workshops were presented by staff from either the Solana 

Center or the MRCD. They included presentations and handouts identifying resources 

available to equestrians. Information presented included local watershed awareness, 

manure management, and composting. Key elements included how proper manure 

Page 1


management relates to horse health, water quality, and maintenance of positive 

relationships with neighbors. Question and answer sessions were conducted in all 

workshops. 

The workshops in Lakeside and Fallbrook were held on Saturday mornings on private 

properties with horses and active compost piles at each location. Participants were 

encouraged to observe the compost piles and the BMPs in place to prevent 

contamination of runoff. The presentation at the Fallbrook workshop included poster 

boards of a Power Point presentation. The other two workshops (Ramona and Bonita) 

were held in classroom settings at community meeting rooms on weeknight evenings. 

Presentations were casual discussions that included BMPs to improve horse health, 

protecting properties from erosion, and preventing polluted runoff discharges. San 

Diego County watershed maps were displayed at all workshops, allowing attendees to 

locate their local watershed. 

Assessment was conducted in the form of pre- and post-workshop surveys. 

Community Events 

County staff and/or contractors also provided targeted outreach to the equestrian 

community at four equestrian themed community events during FY09-10. At each of 

these events, the County staffed a booth, answered questions from attendees, and 

disseminated information on manure management, composting, and erosion control 

practices. A watershed map was displayed and participants were asked to complete 

surveys assessing general knowledge and awareness. Additional details on each 

community event are provided in the table below.

Development and Distribution of Educational Materials 

During FY09-10, County staff created a coloring sheet and handout to direct interested 

equestrians to more detailed information regarding BMPs for manure management (see 

attached). 

Surveys 

In order to promote knowledge, awareness, and proper manure management among 

horse owners in the unincorporated areas, the County contracted a firm with expertise 

in Community Based Social Marketing (CBSM) to conduct research to: 1) identify the 

specific manure management actions currently taken by horse owners, and 2) identify 

the barriers and benefits to proper manure management. Research included in-person 

interviews with horse owners in the unincorporated communities of Lakeside and 

Ramona. Intercept interviews were conducted at four retail outlets (feed stores) to 

reach a diverse set of horse owners. Interviews took place between June 16 and June 

27, 2010. A total of 96 horse owners were interviewed. The results of these interviews 

were summarized in a final report that contains key findings and recommendations for 

future outreach and program development (see attached report). 


This activity will assist the County to achieve compliance with the multi-watershed 

Bacteria TMDL for beaches and creeks, and with other more localized TMDLs for 

constituents such as nutrients and sediment. 


Additional workshops are planned for equestrians in the Santa Margarita and San Luis 

Rey Watersheds during FY10-11 and FY11-12. In addition, the County is pursuing a 

partnership with the San Diego County Equestrian Foundation (SDCEF) to disseminate 

information about manure management and other BMPs to the equestrian community. 

County staff will provide outreach at various SDCEF events during FY10-11. Over the 

long term, the County is interested in pursuing opportunities to facilitate peer mentoring 

programs that encourage equestrians to learn about proper BMPs such as manure 

management from one another. Development of such a program in the future is 

contingent upon identifying a reliable source of funding such as grants.

Providing education to the equestrian community is consistent with the Collective 

Watershed Strategy in that it promotes source control for high priority water quality 

problems in this watershed. 


To assess changes in knowledge and awareness (Level 2 Outcomes) among 

participants in the workshops described above, pre- and post-workshop surveys were 

administered. 

Pre-workshop survey results were as follows: 

• 15.2% of participants responded that they live in a watershed. 

• 43.2% responded that stormwater is not treated. 

• 10.8% felt that horse manure contributes from “some to a great deal” to water 

pollution. 

When asked about what equestrians can do to prevent pollution caused by horse 

manure, 59.5% of respondents suggested ideas on the pre-workshop survey. 

Post-workshop survey results were as follows: 

• 90% of respondents indicated that they live in a watershed. 

• 74.2% responded that stormwater is not treated. 

• 22.8% felt that horse manure contributes from “some to a great deal” to water 

pollution. 

Regarding what equestrians can do to prevent pollution caused by horse manure, 

82.8% suggested ideas on the post survey. 

These survey results indicate a positive increase in knowledge and awareness about 

how equestrian activities can affect water quality. Results also show that more 

equestrians were able to identify positive behavioral changes (Level 3 Outcomes) 

following the workshops.

Residential Rain Barrel Subsidies & Distribution 

SDR-A71 


The County of San Diego will implement a rain barrel subsidy and distribution program 

targeting residents throughout the County. Rain barrel use will be encouraged through a 

subsidy eligible to residents of unincorporated areas, but residents of incorporated cities 

will also be able to purchase rain barrels at an affordable price. In addition to distribution 

of rain barrels, the program will promote outdoor water conservation and runoff 

reduction through public outreach before and during rain barrel distribution events. 

Use of rain barrels can provide many benefits including reduced reliance on potable 

water through the storage and use of rain water for irrigation. For example, one inch of 

rain falling on a 1,000 square foot roof can harvest 600 gallons of rainwater. Retention 

and use of rain water onsite reduces the overall loading of pollutants leaving properties 

and entering the stormwater system. By implementing a rain barrel system, residents 

can: 

• Reduce water pollution as a result of rainwater runoff, which carries pesticides, 

fertilizers, sediment, oil, and trash into local rivers and lakes. 

• Reduce soil erosion and improve the ability of water to infiltrate the soil at a 

reduced intensity. 

• Reduce dependency on imported water supplies and realize cost savings as a 

result of reduced water use. 

• Help save energy by reducing demand on our drinking water supply. 

In addition to the provision of rain barrels, County staff will be present at distribution 

events to provide educational materials and responses to any questions raised by 

participants. Residents from multiple watersheds are expected to participate in this 

regional activity and will be asked to sign a maintenance agreement as a condition of 

receiving a rain barrel at the subsidized rate. 

Follow up surveys will be conducted with participating residents to ensure that rain 

barrels have been installed and to encourage proper maintenance. 

ACTIVITY IMPLEMENTATION FY09-10 

Activity during FY09-10 included conducting research to identify desired rain barrel 

features, including: size, ease of installation, cost, and features to discourage mosquito 

breeding. The County solicited bids through a formal procurement process in order to 

obtain the best quotes for provision of rain barrels and for one-year of customer service 

assistance following distribution. A vendor was selected, a contract awarded, and 

planning was initiated for two distribution events to be held during FY 10-11. In addition, 

Page 1


the County used an existing website to provide more information to the public 

(www.rethinkwateruse.org). 


This activity was not specifically implemented in compliance with a TMDL. 


Planning for this activity occurred during FY09-10. The events are scheduled to occur 

during FY10-11. Depending upon the success of the initial events, additional events will 

be considered for implementation during FY11-12 and FY12-13.

Rainwater harvesting reduces the overall amount of runoff from individual properties 

resulting in a decrease in pollutant mobilization and erosion. 


Level 1 Outcomes were achieved through the number of rain barrels sold to individuals 

living in the County and through the signing of rain barrel maintenance agreements.

Water Quality Activity 

TITLE: 

Addition of Infiltration Strips to Concrete Channels 


The City of Santee has received preliminary approval for funding of a pilot project through 

the San Diego Region Integrated Regional Water Management Plan (IRWMP). The project 

has been designed specifically to address water quality issues relating to concrete 

channel-lined drainage. The City has been successful in restoring portions of unlined 

channels such as Forester Creek and Woodglen Vista Creek. However, it is not possible 

to implement restoration in concrete channels where there is existing development, for 

example in the upper portion of the Woodglen Vista Creek, which is surrounded by 

residences. 

The City is proposing to conduct a pilot project to explore how infiltration can be introduced 

at the base of concrete channels to facilitate infiltration of dry weather (and to some extent 

wet weather) flows. This would mimic the pre-development hydrology of the drainage 

channel and help recharge groundwater. 

Infiltration of runoff will divert pollutants from being discharged to the San Diego River. 

Some designs may allow the recruitment of plants in the infiltration areas which will help 

remove pollutants such as nutrients from the run-off. The objective of the project is to 

achieve some of the benefits of restoration without compromising flood control capacity 

and function. 

This project complements other projects the City is undertaking to survey the condition of 

corrugated metal pipe (CMP) portion of the storm drain system and to prioritize CMP 

replacement. 



With input from City of El Cajon, City of San Diego, City of La Mesa, and County of San 

Diego. It can also be considered a regional collaborative effort due to its integration into 

the IRWMP process for San Diego County.

WURMP meetings to allow other jurisdictions to comment on the pilot project design. Input 

from other jurisdictions is needed so that the findings, if the project is successful, it can be 

used to design similar facilities in their jurisdictions. 

Infiltration of runoff, if implemented throughout the watershed will potentially help achieve 

TMDL compliance. 

TASKS TO BE IMPLEMENTED DURING FY 2010-2011 

The City will begin planning and seeking funding for this activity during FY 2010-2011. The 

project will be implemented when funding becomes available.

ACTIVITY A-9 SUPPORTING DOCUMENTATION: I LOVE A CLEAN SAN DIEGO – 

CREEK TO BAY CLEANUP EVENT

25 th Annual California Coastal Cleanup Day 

FINAL REPORT—San Diego County 

Event Overview 

The 25 th Annual California Coastal Cleanup Day was held on Saturday September 19th, 2009 from 9am 

to 12noon in San Diego County. This year’s event celebrated the 25 th anniversary of California Coastal 

Cleanup Day, and the 24 th anniversary of the International Coastal Cleanup. I Love A Clean San Diego 

(ILACSD) and San Diego Coastkeeper (SDCK) coordinated the effort once again in San Diego County. As in 

past years, ILACSD coordinated all inland cleanup sites while SDCK coordinated all coastal sites. This was 

the sixth consecutive year that San Diego Coastkeeper was involved as co‐coordinator of the event and 

the twenty‐third year that ILACSD has been involved. 

California Coastal Cleanup Day is part of International Coastal Cleanup (ICC), a global volunteer initiative 

organized by the Ocean Conservancy. Each year, the majority of U.S. states, and over fifty countries 

worldwide participate in the largest international volunteer event in support of the marine 

environment. ICC is unique in that all volunteers are asked to track the debris they collect by completing 

data cards provided by The Ocean Conservancy. These cards track the type and amount of trash and 

recyclables collected at each site, as well as identify certain items of local concern, including cigarette 

butts, fishing line, and food wrappers. These data cards are entered into a comprehensive online 

database managed by the Ocean Conservancy and are used to determine sources of marine debris and 

pollution trends, making volunteers an important part of a global marine pollution study. 

This year Coastal Cleanup Day broke volunteer records once again, making this year a continuation in 

the tradition of increased volunteer support locally year after year. In San Diego County, 10,283 

volunteers participated in Coastal Cleanup Day at 80 sites countywide. Six of these cleanup sites were 

hosted by Proyecto Fronterizo across the border at beaches in Tijuana. Of all cleanup sites, 38 were 

coastal and 42 were inland, further demonstrating the shift to inland sites as many local beaches have 

less of a problem with litter. These volunteers removed an impressive 174,491 pounds or 87 tons of 

trash, recyclables, and green waste from cleanup sites, showing an increase in the amount of trash 

collected when compared to 2007 and 2008 debris totals. 

Community Participation 

Volunteers 

San Diego County volunteering reached a milestone this year, with over 10,000 

individuals giving their time to Coastal Cleanup Day. This was more than a 25% 

increase from 2008, when there was a similar jump in numbers from the 

previous year. Many volunteers came with their family or were part of 

community service groups, including company teams, scout troops, and school 

groups. Coordinators hope to encourage youth participation each year to create

environmental stewards at a young age. To reward and engage these youth volunteers, scout troops 

can earn commemorative event patches for their service, and volunteers in grades K – 6 can enter a 

coloring contest for a prize and recognition on the website. This year’s Coloring Contest theme asked 

students to create their own CCD mascot to act as a cleanup champion for clean communities, and 

winners from each grade were rewarded with an art kit. 

In order to accommodate the increasing numbers of volunteers, 4 more sites were added and each site 

captain was given more supplies. This year’s 80 sites reached over 150 miles of shoreline, spanning 

across the majority of the coastline from Oceanside to Rosarito, Baja California, and inland sites as far 

north as Fallbrook and as far east as El Cajon. In total, 10,283 participants removed 124,236 pounds of 

trash and 50,255 pounds of recycling for a total of 174,491 pounds or 87 tons of debris. San Diego 

County had some of the highest accomplishments of coordinating groups in the state of California, 

where over 78,000 volunteers removed over 1.2 million pounds of debris. San Diego ranked third after 

Los Angeles and Orange counties in terms of volunteer totals in California. San Diego ranked 2 nd only to 

Los Angeles County for the most debris collected. 

Each coordinating organization enlisted the help of many 

student volunteers to help with this event. These volunteers 

were called on to help prepare each site’s supplies, distribute 

materials to site captains, and to manage registration and food 

at the media site on the day of the event. Some volunteers also 

helped tabulate data cards after the event. In total, 187 

volunteer hours were spent on such activities.

Over 7,500 volunteers registered prior to the cleanup on the San Diego Coastal Cleanup Day website, 

www.cleanupday.org. This website is regularly maintained by the event coordinators with updated 

information about site locations, special instructions, scout patches and coloring contests, and press 

releases/photos/news. Tracking online registration is an important part of distributing volunteer groups 

to sites with fewer volunteers, as coordinators are able to set a reasonable cap on registration for some 

of the more popular sites. While it is recognized that a number of registrants will not actually attend, a 

similar number will attend without registering. Urging volunteers to register is an important part of 

managing such a large simultaneous event, and accessing that information through the website helps to 

prepare site captains for the expected number of attendees. Red 

text is used in the weeks leading up to the event to further 

encourage participation at sites in need of volunteers. 

Coordinators recommend adding differentiation for full sites as 

well so they stand out against sites that are open. There are 

opportunities to better match the actual capacity of certain sites 

with the cap set on registration at the website and the quantity of 

supplies provided. Coordinators hope to further streamline this 

© Matthew Meier Photography process next year. 

Site Captains 

ILACSD and SDCK are greatly appreciative that many site captains were experienced returning veterans 

for their site. However, it is inevitable that some captains cannot continue the level of commitment 

necessary to make the event a success, and some sites required recruiting new eager site captains. Site 

captains are often associated with a community group or local government agency, or an organization 

dedicated to supporting the environment. Since many captains work with co‐captains, there were well 

over 100 site captains and co‐captains for 80 sites at Coastal Cleanup Day 2009.

Site captains are strongly encouraged to attend one of two 

training meetings one month before the event to distribute their 

cleanup supplies and for updates on any news or changes. As an 

incentive to attend, captains are treated to dinner and 

entertainment (in the form of a brief educational PowerPoint 

presentation on marine debris and the history of Coastal Cleanup 

Day). The meetings were held from 6:00‐7:30 pm on Tuesday 

August 11 th at the Oceanside Library Civic Center Community 

Room and on Monday August 17 th at the Naval Training Center Command Center in Point Loma. 

Statewide coordinators from the Coastal Commission were able to attend and introduce themselves at 

both meetings; Shannon Waters attended the North County meeting and Eben Schwartz attended the 

Point Loma meeting. Both meetings had impressive attendance, although due to conflicts some site 

captains were required to pick up their supplies from the ILACSD or SDCK offices and receive a brief 

tutorial. 

Site captains are responsible for reporting their total volunteer count and trash weight, along with any 

hazardous waste for pick up, to the coordinators by 12:30 pm on the day of the cleanup. While some 

follow up calls were necessary, over 85% of totals were recorded before the distribution of the final 

press release. There are always captains who fail to complete data cards, or do not tally their sites data 

cards on the site captain summary card, leading to some extra follow up by coordinators after the event. 

Marketing & Media 

Coordinators decided to hire a professional marketing, advertising 

and public relations agency, Oster & Associates to help with media 

buys, press releases and overall event branding this year. Focus was 

placed on the 25 th anniversary component, as well as the bi‐national 

aspect of San Diego’s Coastal Cleanup Day to garner more media 

attention. Coordinators created and disseminated two pre‐event 

press releases, one media advisory, and one post‐event release. 

Outreach was also done by printing 1,000 posters and 5,000 flyers 

recognizing event sponsors and directing potential volunteers to the 

local CCD website, www.cleanupday.org. The posters were once 

again printed with both English and Spanish text on one poster, and 

the two different versions of the flyers were available, one in English 

and one in Spanish. These documents were also sent out 

electronically to all site captains to further disseminate to all email 

contacts. 

Belmont Park in Mission Beach was chosen as the location for this year’s media site. This site was 

chosen for a variety of reasons, including its central location, local landmark status, substantial parking 

in multiple lots, ability for volunteers to spread out in a large cleanup area, and a new partnership with 

Belmont Park through Wavehouse and the San Diego Coaster Company. In order to manage the 

expected 500 + volunteer turnout, ILACSD coordinated a variety of service projects at this site including 

storm drain stenciling and stenciling beach rules on the boardwalk and seawall. 

ILACSD & SDCK updated the “how you heard about the event” field in the online registration form to 

reflect current media partners as well as other outreach means including schools, sponsors, word of 

mouth, internet, etc. This field was made mandatory as part of the registration process. A complete 

breakdown of how registered volunteers heard about the event is shown in the table below. The

feedback shows that online and social marketing and media is an excellent method of reaching a wide 

audience. Coordinators anticipate a heavier emphasis in online marketing next year, as well as targeting 

media that will more effectively reach members of the Hispanic community, which makes up 30% of the 

population of San Diego County.

With the help of Oster & Associates, coordinators 

were able to get proposals from a variety of 

television and radio stations in order to find the 

best partnership at a competitive price. 

Coordinators received proposals from the 

following stations: Star 94.1, KPRI 102.1, Sophie 

103.7, 10News, Fox5, Azteca America, Univision 

TV, Radio Latina 104.5 and La Nueva 106.5. 

Television 

Coordinators worked with media partners ABC 

10News and Univision TV to conduct crossplatform 

outreach in both the English and 

Spanish language. This marked the 4 th year that 

ABC 10News has acted as the English language 

television partner providing hundreds of spots as 

well as web presence and an emcee for the 

media site. The station produced pre‐event public 

service announcements of the following lengths: 

:04 seconds, :05 seconds, :10 seconds, :15 seconds, and :30 seconds. Tracking was provided showing the 

air date, length, and timeslot for each airing. ABC 10News also produced a post‐event PSA in lengths of 

:04 seconds, :15 seconds, and :30 seconds. Online hits were also tracked, with a .03% click and read rate 

from their web banners. Out of over 3 million impressions, 891 impressions were clicked and read. 

While ABC 10News did air an impressive number of spots, their new shift away from community news 

and toward “hard news” has encouraged coordinators to reach out to other stations for the 2010 event. 

This year coordinators chose to reach out to other Spanish language television stations as media 

partners, since previous years Spanish language media outreach was fairly unsuccessful with the current 

measuring system. Univision TV Channel 17 was chosen as the Spanish language television partner due 

to the popularity of their nationally syndicated “novellas” as well as their local morning and evening 

news programs. Univision offered a Coastal Cleanup Day representative the opportunities to be 

interviewed for their morning show, Despierta San Diego, of which ILACSD staff member Gilberto Alfaro 

attended. Univision aired a total of 62 spots while their sister station Telemundo also aired 60 spots. 

Radio 

Again, coordinators received proposals from a variety of stations in order to truly select the best 

partnership to promote the event. Past CCD media sponsors KPRI 102.1FM and Sophie 103.7FM 

submitted proposals, as did Star 94.1FM, a station that has never promoted Coastal Cleanup Day. While 

their advertising rates were a bit more expensive, their audience was larger than any other station and 

the opportunity to advertise during the hugely popular Jeff & Jer Morning Show encouraged 

coordinators to choose Star 94.1FM. However, the morning show which had been on air for over 20 

years was cut right before the advertising campaign began, marking a very sudden and potentially 

negative change in programming. Star 94.1FM aired 54 spots, 14 of which were 30 seconds and 40 of

which were 15 seconds in length. They also provided an appearance by popular morning and afternoon 

show personality, Delana at the media site, which added to the event. Clear Channel, the owner of this 

station also put together a 30 minute pre‐recorded interview featuring SDCK & ILACSD Executive 

Directors Bruce Reznik and Pauline Martinson, which aired across all of their stations in San Diego 

multiple times. Radio Latina aired a total of 51 spots varying in length from 10 seconds, 30 seconds, and 

60 seconds. Radio Latina also adopted two sites, one in Tijuana and one in Imperial Beach, encouraging 

listeners to attend one of these two sites depending on which side of the border they live on. Their two 

morning show personalities, Jesse and Nelly, attended one of the two sites, and used live call‐ins during 

the event to compete for who could get the most volunteers at their respective site. As a result, both 

sites boomed with volunteers as well as fun festivities during and after the cleanup. 

Print 

Several local papers and magazines covered Coastal Cleanup Day in San Diego County, both before the 

event and after its completion. These include The Union Tribune (5X), The Carlsbad Sun, The Peninsula 

Beacon, Beach and Bay Press (2X), Carmel Valley Leader (3X), Coronado Eagle and Journal (4X), Del Mar 

Times (5X), East County Magazine, Eagle and Times (3X), El Mexicano (2X), La Jolla Light, Lavender Lens, 

La Jolla Village News, North County Times (3X), Pacific San Diego Magazine, Rancho Santa Fe Record 

(3X), Rancho Santa Fe Review (2X), Presidio Sentinel (2X), San Diego News Network, Del Mar Village 

Voice, Fallbrook Bonsall Village News, and Mission Times Courier (2X). 

Online 

Most online marketing directed potential participants to visit the 

www.cleanupday.org website for more information and to register for a site near 

them. ILACSD and SDCK highlighted Coastal Cleanup Day as a major volunteer 

opportunity on both of their websites and through regular email alerts. The 

www.cleanupday.org website also allows for an email blast to be sent to all 

previously registered participants, and coordinators sent this reminder when online 

registration opened on August 1 st . As mentioned, ABC10News, Univision, and Star 

94.1 posted information and links on their websites. A link was made available on 

the Belmont Park Roller Coaster Website advertising that viewers could get a free 

ride on the rollercoaster just for volunteering, and led participants to the 

registration website. Many site captains’ organizations internally advertised the 

event through email blasts or by posting a link on their website. An email was also 

sent to San Diego Unified School District Teachers advertising the event, and save 

the date flyers were distributed to Girl Scout Troop leaders at a meeting early in the 

summer. Finally, a Facebook event page was created for the San Diego County 

Cleanup where Facebook members could find more information, RSVP, post photos, 

ask questions, or make comments about the event. 

New in 2009 

Online Post‐Event Survey 

A few changes were introduced at this year’s Coastal Cleanup Day Conference with the California 

Coastal Commission. Surveys were introduced in 2008 in a select few counties that could coordinate it 

last minute, including San Diego. ILACSD and SDCK chose a few sites to test the surveys based off of the 

experience level of the site captains. This year, the CCC encouraged all county coordinators to use 

surveys, and San Diego planned to implement them countywide. However, the CCC was delayed in 

sending out the surveys, so they were not included in each site captain box. ILACSD and SDCK did not 

receive surveys until the week leading up to the event, leaving little time to distribute and explain to

captains with such short notice. To remedy this, ILACSD printed surveys to distribute to attendees at the 

media site, and planned to send out surveys digitally to volunteers in the post‐event thank you email. 

This additionally saves on paper and resources for a more sustainable event. 

Online Data Collection System 

The Ocean Conservancy presented a new online data collection system at this year’s conference. Rather 

than sending in each data card and summary card as in years past, coordinators will log into an online 

database to report data from each summary card. The Ocean Conservancy created the initial county 

profile with a list of cleanup sites that coordinators can log into and edit each year. Summary cards are 

entered online, giving coordinators immediate access to data and trends calculated countywide. 

Crystal Geyser Water Partnership 

A partnership with Crystal Geyser was established in 2008 to provide water donations for many counties 

at a statewide level. The Coastal Commission made an error with order deadlines, and water deliveries 

could not be secured in time for the first site captain meeting in North County. ILACSD worked with the 

local Crystal Geyser contact, Bob Flavin, as well as the statewide contact, Jackie Suzuki, to work out a 

solution. Water coupons were mailed for distribution to all of the North County site captains that 

attended the first site captain meeting in Oceanside. Recommended stores for redemption included 

Stater Brothers, Vons, Albertsons, and Wal‐Mart. Coordinators did not receive any complaints regarding 

the coupons from site captains. The CRV added cost may be an issue pending further review. 

Site Captain Appreciation Event 

Additions were made at a local level to the San Diego County event. Coordinators secured Belmont Park 

and the San Diego Coaster Company as sponsors of this year’s event, who provided each volunteer with 

a roller coaster ride pass. This sponsorship also provided the venue, food, and service staff for the first 

ever Site Captain Appreciation Night. Wavehouse, a part of Belmont Park in Mission Beach, hosted the 

event. Site captains were encouraged to return their supplies while also enjoying food provided by 

Wavehouse, beer provided by CCD sponsor Alaskan Brewery, and other refreshments from Wavehouse. 

Photos submitted for the photo contest were shown on a slideshow during the event, and winners were 

announced for categories that included 

Volunteers in Action, Group Photo, Kids, 

and the best Before and After shot. The 

photo contest was another new addition, 

and was a successful way to encourage 

captains to submit photos to coordinators. 

ILACSD and SDCK facilitated conversation 

amongst site captains through an ice 

breaker bingo game, and did a short 

presentation of site captain stand out 

awards. Awards included best rookie 

captain, most trash removed, most trash 

removed per volunteer, and best all 

around captain, each for coastal and inland 

sites. A “Golden Grabber” award was 

presented to Jane Donely for her 20 th 

Anniversary as a site captain with Coastal 

Cleanup Day.

This event was not only a fun and relaxing way to get to know site captains better, but also proved to be 

a great way to get supplies back in a timely fashion. Some site captains who were not able to stay for the 

event still came simply to drop off their supplies, as the “after‐hours” timing seems to work better for 

many people’s schedules. This event, held four days after Coastal Cleanup Day provided site captains the 

opportunity to share their site results and experiences. Spreadsheets with totals from all sites were 

printed out and placed at each table to help facilitate conversation. Site leaders were also able to bring 

their children to the event, as the venue had games for both kids and adults to engage in. 

Sempra Volunteer Service Projects 

The Sempra Energy Foundation partnered with ILACSD for the second year to organize five Coastal 

Cleanup Day sites chosen for Sempra employees. To keep an expected 200 volunteers occupied and 

engaged at each site, ILACSD coordinated service projects to compliment the debris removal at one 

cleanup site in each of the five zones. Sempra asked for sites near their main offices and recommended 

targeted communities to hit, including National City and Carlsbad. Sempra volunteers could choose 

from the cleanup option or the side projects at each of their cleanup sites. Below is a list of the service 

projects coordinated for Sempra volunteers in San Diego County: 

Zone 1: North County Coastal 

Carlsbad State Beach campgrounds: Campground renovations and amphitheater mural 

Zone 2: North County Inland 

Dixon Lake: Kayak cleanup, trail maintenance, and bridge installation 

Zone 3: Central San Diego 

Belmont Park Media Site: Storm Drain Stenciling and stenciling beach rules on the seawall 

Zone 4: East County 

El Cajon Rose House: Landscaping and facelift for foster care center 

Zone 5: South Bay 

Paradise Creek Educational Park: Upland creekbed restoration, native planting 

When coordinating service projects, a few characteristics were used to qualify sites. Veteran captains 

that have a history of efficiency were selected because of their ability to handle the added responsibility 

successfully. Sites also needed to have enough trash and need for additional work, and enough space 

for the added large group of volunteers. Projects were selected that were varied from the rest, to 

occupy an assortment of age ranges and physical abilities to satisfy Sempra’s diverse volunteer base. 

The Paradise Creek site was promoted as the family friendly site, and the Dixon Lake was marketed 

towards sturdier volunteers ready to work hard. 

Team Sempra hand selected leaders from their employee base to ensure that volunteers were qualified 

as a point of contact for the project. Last year, they asked for employee volunteers and had some 

problems with scheduling and training before the event. By selecting candidates that they felt would be 

up to the challenge, each team leaders was very helpful and easy to work with. Site visits were 

scheduled in the weeks leading up to the event. These meetings were very beneficial and crucial to the 

event’s success. Each site captain got to meet the Sempra team leader and discuss supplies, logistics, 

and give the Sempra employee a specific idea of the layout and plan for the event.

To coordinate supplies, each site captain utilized their knowledge and expertise at each of their sites to 

establish a supply list of needs for their projects. ILACSD approved the budget and allowed captains to 

purchase supplies. Receipts were required from each captain for reimbursements. Team Sempra 

provided pizza from Oggi’s for all volunteers at each of the five sites. Some site captains arranged for 

extra snacks or drinks to compliment the lunch. In addition to pizza arrangements, ILACSD coordinated 

with Sempra to reserve parking spots for Sempra executives that were assigned to each site. 

One Sempra volunteer advised that coordinators provide masks for any project that used paint. This 

should be taken into consideration for next year’s event. All other feedback provided by Sempra 

volunteers and event coordinators was extremely positive. ILACSD plans to meet with Sempra to discuss 

an overview of the event, including pros and cons before beginning to plan for the 2010 event.

1 INTRODUCTION 

On July 15, 2004 the County of San Diego received Proposition 13 funding from the State 

Water Resources Control Board (SWRCB) to perform conveyance restoration and to 

construct a Best Management Practice (BMP) water quality detention basin (Woodside EDB) 

to treat urban runoff from the Winter Gardens sub-watershed. This runoff discharges directly 

into the San Diego River. This report presents the annual water quality sampling results for 

Woodside EDB in order to assess its effectiveness in pollutant removal and load reduction. 

During FY 2009-2010, water quality and flow at the inlet and the outlet of Woodside EDB 

were monitored over three dry weather and three wet weather sampling events. Dry weather 

monitoring was conducted in August 2009, March 2010, and June 2010; dry weather 

conditions were defined as following an antecedent dry period of at least 72 hours or after the 

EDB has returned to its base flow conditions. Wet weather monitoring was conducted during 

and/or directly following storm events of at least 0.10 inches of rainfall.

2 DESCRIPTION OF SAMPLING PROCEDURES 

2.1 Flow Measurement 

Instantaneous flows were measured at the influent and effluent during non storm flow 

conditions only; no flow measurements were made during storms due to safety concerns. 

Flow rates were estimated by multiplying flow velocity readings from a hand-held 

mechanical current meter by direct water depth and channel width measurements. Staff 

gauges were not used to estimate flow because accumulated sediment in the outlet and inlet 

channels prevented accurate estimation. The results are summarized in Table 1 below. 

Table 1. Instantaneous Flow Measurements 

Date Inlet Flow (cfs) Outlet (cfs) 

8/19/2009 0.126 0.030 

3/3/2010 0.317 0.234 

6/29/2010 0.189 0.034 

2.2 Water Quality Sampling 

During FY 2009/2010, three dry weather events (in August 19, 2009, March 3, 2010, and 

June 29, 2010) and three wet weather events (January 19, 2010, April 12, 2010 and April 21, 

2010) were sampled. One set of water quality grab samples were collected at both the 

influent and effluent sampling points during each sampling event. Grab samples were 

collected in pre-cleaned laboratory-supplied sampling bottles. Samples were labeled, placed 

in a cooler on ice and transported under proper chain-of-custody documentation to an 

analytical laboratory for analysis. The samples were analyzed for the constituents listed in 

Table 2. During the sampling of the inlet and outlet, field measurements were also collected 

for pH, conductivity, temperature, dissolved oxygen, and turbidity. The field measurements 

are described on Table 3. Field data sheets were also completed for each site during each 

sampling event and are included in Appendix A.

3 RESULTS 

The results of the 2009-2010 monitoring study are summarized in Table 3. The Laboratory 

analytical reports are included in Appendix B. Table 4 shows the inlet/ outlet percent 

differences in constituent concentrations and field-measured parameters including pH, 

temperature, conductivity, dissolved oxygen and turbidity. Percent differences between the 

inlet and outlet constituent loadings are presented in Table 5. The percent differences were 

calculated for dry weather results only as discharge rates were not measured for wet weather 

flows during fiscal year 2009/2010. 

For field-measured parameters (Table 4), a 4% average decrease in pH was observed between 

the influent and effluent ends of the Woodside EDB during dry weather; no difference was 

detected during wet weather. Also during wet weather, there was a mean 31% increase in 

conductivity at the EDB outlet. Turbidity was also higher at the outlet than at the inlet and 

dissolved oxygen concentration was lower at the outlet. 

With respect to percent differences in constituent concentrations between the EDB influent 

and effluent (Table 4) during dry weather, only nitrate and TDS showed lower concentrations 

at the outlet than at the inlet; mean concentrations of all remaining constituents were higher 

at the outlet of the EDB. During wet weather, decreased TSS, TOC, DOC and metal 

concentrations were observed at the outlet while TDS, hardness, and nutrient concentrations 

were higher at the outlet than at the inlet. 

When constituent loadings were considered (Table 5) for dry weather flows only, all but 

three constituents showed mean load reductions between inlet and outlet of the EDB. The 

three constituents that had the higher mean loads at the outlet included total phosphorus, total 

copper, and total zinc. The loadings of total copper and total zinc were orders of magnitude 

higher at the outlet on March 3, 2010 but they were lower at the outlet on the remaining two 

sampling occasions. Total phosphorus loading was higher at the outlet on two of the three 

sampling locations. Ammonia loading was higher at the outlet on one of the three dry 

weather sampling dates.

4 CONCLUSIONS 

Generally, the results indicate that, constituent concentrations at the outlet of the EDB were 

often much higher than at the inlet. There were, however, overall load reductions for the 

majority of constituents measured during dry weather conditions (wet weather discharge rates 

were not measured therefore wet weather loadings could not be calculated for FY 

2009/2010). This was most likely due to the EDB acting to absorb the runoff containing the 

pollutants before it was able to reach the outlet. The exceptions included total copper and 

zinc. The mean loadings of those constituents were higher at the outlet than at the inlet of 

Woodside EDB due to the much elevated total zinc and copper loadings at the outlet 

observed on one of the three sampling dates (on Marcy 3, 2010). 

In terms of constituent concentrations alone, it may be concluded that the EDB functioned 

well in reducing nitrate-N concentrations in non storm flows and dissolved zinc 

concentrations during wet weather. The concentrations of other constituents measured, 

however, were not consistently reduced and were often higher at the outlet of the EDB. 

These often higher constituent concentrations at the outlet and the very much higher total 

copper and zinc loadings at the outlet on one sampling occasion may have been due to the 

deposition of metals and dust near the outlet as it is located adjacent to a high-traffic road.

Notes and Definitions 

\M-02 The sample for nitrate analysis was preserved rvith H2SO4 after the nitrite poúion of tho analysis was completed to extend the 

holding time for the sample. Nitrate results are corrected for the nitrite contribution per tho method. 

QR-02 The RPD result exceeded the QC limits due to non-homogeneity of sample. 

QM-06 Due to noted non-homogeneity ofthe QC sample matrix, the MS/MSD did not provide rcliable rcsults fo¡ accuracy and precision. 

Sample results fur the QC batch were accepted based on LCS/LCSD percent recoveries and RPD values.

W-02 The sample for nitrate analysis was presened with H2SQ4 after the nitrite portion of the analysis was completed to extend the 

holding time for the sample. Nitrate results are coruected for the nitrite contribution per the rnethod. 

QM-06 Due to noted non-homogeneity of the QC sample matrix, the MS/MSD did not provide rcliable results for accuracy and precision. 

Sample rçsults for the QC batch wero accepted based on LCS/LCSD percent recovefies and RPD values.

QR-04 The RPD between the sample and sample duplicate is not valid since both results are below the reporting limit for this analyte. 

QR-02 The RPD result exceeded the QC limits due to non-homogeneity of sample. 

QM-06 Due to noted non-homogeneity of the QC sample matrix, the MS/N4SD did not provide reliable results for accuracy and precision. 

Sample results fo¡ the QC batch were accepted based on LCS/LCSD percent recoveries and RPD values. 

QM-05 The spike recovery was outside acceptance limits for the MS and/or MSD due to matrix interference. The LCS and/or LCSD were 

within acceptance limits showing that the laboratory is in control and the data is acceptable.

EXECUTIVE SUMMARY 

This report presents results of water quality and water quantity monitoring in the lower San 

Diego River watershed within the County of San Diego jurisdiction. The monitoring, conducted 

from February 2009 through December 2009, included flow rate and constituent loading and flux 

measurements during two wet weather runoff events and one dry weather runoff event. A 

secondary goal was to provide data to the San Diego River Watershed Workgroup during a 

similar effort being conducted within the watershed coordinated by the City of San Diego. 

Samples were collected and analyzed for priority watershed constituents including the following: 

• Nutrients (nitrogen and phosphorus). 

• Bacteria. 

• Human-specific Bacteroides. 

• Total suspended solids (TSS). 

• Turbidity. 

• Total dissolved solids (TDS). 

Dry weather flows were observed at Los Coches Creek at I8 (COSDSDR08) and SDR at 

Riverford Rd. (COSDSDR10). However, measurable flow at Forester Creek at Greenfield Drive 

(COSDSDR07) was present only during one of the two storm events monitored. The three 

sampling locations included in the study exhibited unique characteristics: COSDSDR10 was 

generally ponded with a wide a flood plain and relatively low flow velocities, COSDSRD08 had 

a narrow channel with steep sides that was influenced by continuous dry weather flows and 

relatively high flow velocities during storm events, and COSDSDR07 had channel that was 

narrow and composed of very coarse sand with flow observed only during storms. 

With respect to water quality monitoring, the results of the present study can be summarized as 

follows: 

• Total nitrogen and total phosphorus concentrations generally exceeded Basin Plan water 

quality objectives (WQOs) of 1 mg/L and 0.1 mg/L respectively at all sampling locations 

in storm water flows. During non storm conditions, total nitrogen WQO was exceeded at 

both locations sampled and total phosphorus WQO was exceeded at one of the two. 

• Total phosphorus and TSS concentrations increased with increased flows from storm 

water runoff at all locations monitored. The tendency of phosphorus to bind to sediment 

particles may explain these correlated increases in the concentrations of TSS and total 

phosphorus. 


(COSDSDR08 and COSDSDR10) for all chemical and microbiological constituents 

monitored. 


COSDSDR08 during the February storm for all chemical constituents except TSS; 

bacterial loads were also higher at COSDSDR10. 

• During the December storm, organic nitrogen, TKN, total nitrogen, total phosphorus and 

E. coli loads were higher at CPSDSDR08. Notably, TSS loads were three times higher at 

CPSDSDR08 during December storm while they were only slightly higher at that 

location during the much less intense February storm. As phosphorus, organic nitrogen, 

v



and bacteria may be bound to sediment, this would likely provide some rationale for this 

difference. 

• Total nitrogen and total phosphorus flux (in kg/acre) increased with rainfall amount and 

intensity. 

• Non storm dissolved oxygen concentrations met Basin Plan WQOs at COSDSDR08 and 

COSDSDR10. 


conditions at both locations monitored; during storms, TDS concentrations decreased and 

increased upon return to baseflow as supported by continuous conductivity results. 

• Bacteria concentrations generally exceeded WQOs but Bacteroides testing results were 

not indicative of recent human fecal sources. 

• Although bacterial loads were higher during wet weather than in non-storm flows, 

bacteria flux (loads per acre) values during storms and non-storm conditions did not 

differ significantly among the monitored drainage areas.

1.0 INTRODUCTION 

1.1 Program Overview 

This report presents the results of water quality and quantity monitoring at three tributary 

locations in the lower San Diego River Watershed within the County of San Diego’s jurisdiction. 

The purpose of the study was to characterize drainage areas flow rates and compare constituent 

concentrations and loads between sites. Monitoring was conducted from February 2009 through 

December 2009 by Weston Solutions, Inc. (WESTON®) under contract by the County of San 

Diego. Monitoring was conducted during two wet weather runoff events and one non-storm 

event. Samples were collected and analyzed for priority watershed constituents including the 

following: 

• Nutrients (nitrogen and phosphorus). 

• Bacteria. 

• Human-specific Bacteroides. 

• Total suspended solids (TSS). 

• Turbidity. 

• Total dissolved solids (TDS). 

1.2 Study Objectives 

The study objective was to capture two wet weather runoff events and one dry weather runoff 

event for the purpose of comparing flows and constituent loading and flux within the County of 

San Diego’s jurisdiction. A secondary goal was to provide data to the San Diego River 

Watershed Workgroup during a similar effort being conducted within the watershed coordinated 

by the City of San Diego. Additional study participants included City of El Cajon, City of 

Santee, and City of La Mesa. The constituents, land use types, and pollutant sources selected for 

investigation in this study reflect the priorities of the Watershed Group, as described in the 

Watershed Urban Runoff Management Plan (TRC, 2007). 

1.3 San Diego River Watershed 

The San Diego River Watershed Management Area (WMA) (Hydrologic Unit (HU) 907.00), 

encompassing 277,543 acres, is the second largest WMA in San Diego County and consists of 

four hydrologic areas (HAs): 

• Lower San Diego. 

• San Vicente. 

• El Capitan. 

• Boulder Creek. 

These HAs are further divided into 15 hydrologic subareas (HSAs). The HAs, HSAs, and named 

tributaries are shown on Figure 1-1. For this monitoring effort, sampling locations were limited 

to the County of San Diego’s jurisdiction below San Vicente Reservoir and El Capitan Lake 

dams. The studied drainage areas included El Monte (907.15), Coches (907.14), El Cajon 

(907.13), and Santee (907.12) HSAs (Figure 1-2).

San Diego River Watershed Monitoring – Draft Report May 2010 

1.3.1 Land Use 

Land use classifications within the San Diego River WMA are shown on Figure 1-3 (United 

States (US) land use classification data distributed by SANDAG, 2007). In general, the 

watershed becomes more urbanized from east to west with most land being vacant and 

undeveloped (45%). Other major land uses include open space / parks and recreation (21%), 

residential and spaced rural residential (18%, combined), and transportation (6%). Agriculture, 

commercial, industrial, military, public facility, and water land use classifications each make up 

less than 2% of the acreage. 

Figure 1-3 also presents land use composition of individual HAs. The Lower San Diego HA is 

comprised primarily of residential / spaced rural residential (30%) and open space / parks and 

recreation (25%) land uses with vacant and undeveloped land accounting for 18% of the area. 

The San Vicente HA is primarily vacant and undeveloped (41%) with 34% of the area occupied 

by open space and parks and recreation and 15% classified in the residential / spaced rural 

residential land use category. The El Capitan HA is also primarily vacant and undeveloped 

(77%); open space / parks and recreation and residential / spaced rural residential each account 

for only 9% of the land use. Vacant and undeveloped land accounts for 71% of the Boulder 

Creek HA; other significant uses include open space / parks and recreation (15%) and residential 

/ spaced rural residential (8%). 

The drainage areas studied (Figure 1-4) included primarily vacant and undeveloped land and 

open space/ parks and recreation but also a large proportion of residential and spaced rural 

residential land uses. Directly upstream of the study area, two drinking water reservoirs are 

located: El Capitan Lake and San Vincente Reservoir. These impoundments, maintained by the 

Water Department of the City of San Diego, rarely release water downstream. There were also 

some localized industrial and commercial land uses near the site on Riverford Road 

(COSDSDR10).

1.3.2 Population and Jurisdiction 

The population in the watershed is estimated at 525,000 persons or 1,190 persons per square mile 

(US census data distributed by SANDAG, 2000). The major population center is in the lower 

San Diego HA; which is reflected by the greater proportion of the urban land uses in the lower 

watershed. The area’s population is projected to increase by 12%, reaching approximately 

590,000 people by 2020 (SANDAG, 2005). 

The San Diego River WMA contains the second largest percentage (75%) of unincorporated land 

in San Diego County. The remaining areas of the watershed include the Cities of El Cajon, La 

Mesa, Poway, San Diego, and Santee. 

1.3.3 Beneficial Uses 

The San Diego River WMA provides many beneficial uses with its reservoirs, lakes, rivers, and 

creeks. A listing of the beneficial uses from the Water Quality Control Plan for the San Diego 

Basin 9 (Basin Plan) is presented in Table 1-1. Notable waterbodies in the watershed include the 

San Diego River, Boulder Creek, El Capitan Reservoir, San Vicente Reservoir, Lake Jennings, 

Lake Cuyamaca, and Lake Murray. Principal aquifers include the Santee/El Monte Basin and the 

Mission Valley Basin. In addition to water resources, the watershed contains many parks and 

open space areas including Famosa Slough, a 37-acre wetland near the mouth of the River and 

the Mission Trails Regional Park which provides nearly 5,800 acres of natural habitat and 

recreation areas. Beneficial uses influenced by runoff from the monitored drainage areas are 

limited to areas below the reservoirs.

1.4 San Diego River Total Maximum Daily Load Status 

1.4.1 Regulatory Water Quality Issues 

Impacts to the watershed include surface water quality degradation, habitat degradation and loss, 

invasive species, eutrophication, and flooding (San Diego County, 2009). Section §303(d) of the 

Clean Water Act (CWA) requires that each state identify waterbodies within its boundaries that 

do not meet water quality standards (i.e., beneficial uses, water quality objectives (WQOs), and 

an anti-degradation policy). The CWA also requires each state to establish a priority ranking for 

these impaired waters known as the CWA §303(d) List of Water Quality Limited Segments and 

to establish Total Maximum Daily Loads (TMDLs) for the identified waterbodies. The 2008 

California §303(d) List of Water Quality Limited Segments was partially approved by the 

USEPA on November 18, 2010. Waterbodies in the San Diego River WMA that have been 

placed on the 2008 State Board §303(d) list are presented in Table 1-2. Constituents that have 

been placed on the 2008 State Board §303(d) list for waterbodies throughout the watershed 

include indicator bacteria, TDS, phosphorus, total nitrogen, eutrophication, pH, low DO, color, 

chloride, manganese, selenium, toxicity, and sulfates. Factors that may be impairing water 

quality in the watershed include urban runoff, agricultural runoff, mining operations, sewage 

8



spills, sand mining, and natural sources (San Diego County, 2009). Forester Creek, in upper San 

Diego River, is listed for fecal coliform, pH, phosphorus, TDS, and selenium. Alvorado Creek 

and Los Coches Creek are listed for Selenium.

1.4.2 Bacteria Project I Total Maximum Daily Load and Bacteria Source 

Discussion 

1.4.2.1 Bacteria Project I Total Maximum Daily Load 

The State Water Quality Control Board (SWQCB) adopted on December14, 2010 the Basin Plan 

amendment, to incorporate indicator bacteria TMDLs developed in the Project I – Twenty 

Beaches and Creeks in the San Diego Region (including Tecolote Creek) (Resolution R9-2010- 

0001, February 10, 2010). Project I was initiated in 2003 and several iterations of TMDL 

adoption and revision occurred. The TMDL was originally adopted in 2007, but was later 

revised. The Bacteria I TMDL Project is still pending review by USEPA. The most recent 

TMDL involved calculating TMDLs for numerous surface waters throughout San Diego County 

and includes the San Diego River. The County of San Diego is named as the responsible party in 

the TMDL for multiple waterbodies, including the San Diego River. The numeric targets listed in 

the Basin Plan Amendment are presented in Table 1-3 for wet weather and Table 1-4 for dry 

weather.

2.0 STUDY DESIGN 

Two wet weather and one non-storm (dry weather) events were monitored in 2009 at three sites 

within the County of San Diego’s jurisdiction (Figure 1-2). 

2.1 Study Duration 

The study was conducted from January 2009 through December 2009. 

2.2 Sampling Locations 

Three sampling locations were chosen: One site (COSDSDR10) was located on the mainstem of 

the San Diego River at Riverford Road. The second site (COSDSDR08) was upstream in the Los 

Coches tributary and was co-located with a USGS gauging station. The third site (COSDSDR07) 

was in the upper Forester Creek tributary. A map of the locations is presented in Figure 1-2 and 

site photos are shown in Figure 2-1 through Figure 2-4. A fourth site (COSDSDR28) was 

considered but was not monitored as it had no flow during the study’s time period.

Dry weather monitoring was conducted during April 21–22, 2009. There was an antecedent dry 

period of four days prior to the monitoring event. Only two of the three sampling locations were 

monitored (Table 2-2); Forester Creek (COSDSDR07) was not sampled as it was dry. 

WESTON collected and analyzed one 24-hour time-weighted composite sample from each 

location. Sample pacing was set to collect one 250-mL sample per 20-minute period for a total 

of 18 L using a Sigma 900 SD sampler with Teflon tubing and a 10-L glass composite bottle. 

The samples were analyzed for chemical constituents presented in Table 2-5. 

16



Wet weather monitoring was conducted over two storm events at three sampling locations as 

outlined in Table 2-2. A total of six grab samples were collected at each site per storm over a 

pollutograph and tested for chemical constituents listed in Table 2-5. 

Grab samples were also collected for microbiological analysis. During dry weather, one grab 

sample was taken every six hours for a total of five at each site. During storms, bacterial 

samples were collected over a pollutograph. Bacteria samples require clean handling techniques 

for PCR analysis (WESTON Bacteroides/PCR Field Sampling SOP–FLD031.01). Only PCRtrained 

personnel conducted the sampling. The bacterial samples were analyzed individually. 

Field measurements were also taken at each location at 15-minute intervals using YSI 6920 v2 

data sondes. 

Quality assurance samples included one duplicate and one field blank per event. Additional 

quality controls included calibration of all monitoring equipment per manufacturers’ 

specifications prior to the monitoring event and the use of proper chain-of-custody procedures. 

Samples were collected in laboratory provided sample bottles with the appropriate preservative 

for each analysis. All samples were immediately placed on ice and transferred to the laboratory 

within the methods’ specified holding times. 

2.3.2 Flow Measurements 

Estimates of continuous flow at each site were made using Sigma 950 Flowmeter with a 

pressure/level transducer. A water level (stream stage) sensor was secured to the bottom of the 

channel at each sampling location. Stream stage measurements at each site were downloaded 

following each sampling event and verified to ensure accuracy. They were then converted to 

discharge rates with head/flow equations developed from stream survey and stream rating data. 

All water level and flow data were entered into the data management system, copied, and 

archived. Data from the USGS gauging station at Los Coches Road (COSDSDR08) was used to 

validate the flow measurements collected. 

2.3.2.1 Stream Surveys 

Channel Cross Section. To produce rating curves for flow estimation, surveys of channel 

cross-sections were conducted at each monitoring site. The surveys involved placing endpoints at 

the highest points of each channel at each bank. A tape was then stretched between the endpoints 

such that the zero end of the tape was attached to the endpoint on the left bank of the channel 

(looking downstream). Channel depth was measured by holding a stadia rod vertical and level 

from the channel bottom to the stretched tape. The channel depth measurements were recorded 

incrementally at equal horizontal distances across the channel for a minimum of 20 

measurements. 

Channel Slope. Channel longitudinal slope surveys, required for rating curve development, 

were conducted using a DeWalt TM Model DW092 transit level. A minimum of three elevations 

at increasing horizontal distances from the transit level were recorded in the channel bed at each 

sampling site. A minimum of five elevations were measured at sites with irregularly sloped or 

curved channel surfaces. The average channel slope was calculated from the survey data. 

17



Stream Rating. To measure instantaneous flow during base flow conditions, a Marsh- 

McBirney Model 2000 Portable Flowmeter connected via a cable to an electromagnetic openchannel 

velocity sensor was used. The velocity sensor was attached to a stainless-steel, topsetting 

wading rod. To construct a transect, measuring tape was extended across the stream 

perpendicular to flow, and secured on both banks approximately 1 ft above water surface. The 

distance on the tape directly above waterline (where water meets the bank) was recorded as the 

initial point. The first three measurements were made at the first point with adequate depth and 

measurable velocity. They included water depth, velocity, and distance from the bank (i.e., the 

initial point). Subsequent depth, velocity, and distance measurements were made incrementally 

across the entire width of the channel; a minimum of 20 points are measured per site. Water 

depth was determined from calibrations on the wading rod in tenths of feet. Velocity 

measurements (in feet per second) were made at each point along the transect by positioning the 

velocity sensor perpendicular to flow at 60% of water depth (from the surface). 

The field measurements were then entered into a computer spreadsheet that calculates the 

stream’s cross-sectional profile (from depth and distance-from-bank measurements). Total flow 

rate across the channel (in cubic feet per second) was then determined by integrating the velocity 

measurements over the cross-sectional surface area of the stream channel. 

2.3.2.2 Rating Curve Development 

The channel survey data were used to produce a rating curve for each sampling site. A rating 

curve or table is a relationship between stage (water level) and flow at a cross section of a river 

or stream and reflects the particular geometry of the given cross section. 

Rating curves were modeled using site-specific survey information with the Manning’s Equation 

as defined by USGS (Rantz, 1982). Using the direct measures of stream discharge collected 

during base flow conditions, indirect stream discharge measurements were calculated for wet 

weather flows using the Equation. Manning’s Equation is an empirical formula for open channel 

flow or for flow driven by gravity, as follows: 

where 

Q = Flow 

n = Manning Roughness coefficient 

A= Cross-sectional area 

R = Hydraulic radius 

S = Hydraulic slope 

The hydraulic radius is derived as follows: 

where 

R = A/P 

A = Cross-sectional area of flow (ft 2 ) 

P = Wetted perimeter (ft) 

18



The Manning’s Equation was developed for conditions of uniform flow in which the water 

surface profile and energy gradient are parallel to the streambed and the area, hydraulic radius 

and depth remain constant throughout the reach. 

2.3.3 Field Measurements 

YSI 6920 Multiparameter Water Quality Sondes were used to monitor temperature, turbidity, 

specific conductivity, pH, and DO (Table 2-3). The Sondes were calibrated prior to sampling 

events. Monthly maintenance was performed on the Sondes, including battery replacement and 

verification of proper operation per manufacturer specifications. Table 2-3 details parameters 

measured.

2.3.4 Microbiological Analyses 

2.3.4.1 Sample Analysis Summary 

Two types of bacterial analyses were completed during the surveys: the enumeration of fecal 

indicator bacteria (FIB) (i.e., total coliforms, fecal coliforms, enterococci, and E. coli), and 

quantitative polymerase chain reaction (Q-PCR) analysis for Bacteroides. Traditional bacterial 

samples were collected to determine the spatial and temporal distribution of FIB. The Q-PCR 

technique was used to amplify the DNA of Bacteroides. Two separate analyses were performed: 

one to determine the presence of general Bacteroides (associated with feces from warm-blooded 

animals) and one to test for human-specific Bacteroides (associated with only human feces). 

Table 2-4 details the microbiology analytical methods performed including detection limits, and 

units of measurement.

2.3.4.2 Sample Handling and Processing 

Fecal Indicator Bacteria 

Field technicians wearing clean, disposable gloves collected 100-mL grab samples in sterile, 

plastic containers containing sodium thiosulfate as a preservative. At locations where sampling 

by hand was not feasible, an extension grab pole was used. Prior to each sample, the pole was 

decontaminated with ethanol and wiped down with Kimwipes®. The bottle was submerged with 

its open-end down below the water surface and then turned up and allowed to fill. The bottle was 

then closed and placed in a plastic bag, sealed, labeled, and placed on ice. Each sample was 

labeled and identified with the project title, appropriate identification number, and the date and 

time of sample collection. The samples and corresponding chain-of-custody forms were 

delivered to WESTON’s Microbiology Laboratory where analysis was initiated within the 

maximum holding time of six hours. 

Total coliform and fecal coliform concentrations were determined using Multiple Tube 

Fermentation Direct Method, whereas enterococcus concentrations were measured using IDEXX 

Enterolert TM technique. The IDEXX Enterolert TM uses a chromogenic substrate test to determine 

enterococci concentrationa, whereas the multiple tube fermentation technique employs a series of 

dilutions to estimate the number of bacteria in a sample. Results of each type of analysis are 

given as the most probable number (MPN) of organisms present. This number, based on the 19 th 

Edition Standard Methods’ probability formulas (Eaton et al., 1995), is an estimate of the mean 

bacterial density per 100 mL of liquid. 

Sample Collection 

Q-PCR analysis was employed to test for presence or absence of Bacteroides. Samples were 

collected with the following “clean hands” aseptic technique: First, the exterior of the Ziploc® 

bag containing the Q-PCR bottle was labeled with sample identification, sample location, sample 

date, sample time, and name of collector using black, waterproof ink. The sampler’s hands were 

sprayed with ethanol and dried. The first pair of gloves was put on and sprayed with DNA 

AWAY, a DNA destabilizing reagent, and wiped dry with Kimwipes®. The second pair of 

gloves was then worn over the first pair, sprayed with DNA AWAY, and wiped dry with 

Kimwipes®. Decontaminated Ziploc® bags were used to store the 250-mL irradiated nucleasefree 

plastic containers before and after sampling. All sample containers were double bagged. 

Prior to opening the outer Ziploc® bag, a Kimwipe® was sprayed with DNA AWAY, and the 

20



seal of the bag was wiped and allowed to dry. The inner Ziploc® bag was then opened, and the 

bottle was removed. The sample container was opened, and the cap was held face down to 

prevent aerial contamination. The sampling container was inverted, allowed to fill, and then 

capped and held in one hand. Excessive water was removed from the outside of the sample 

container using Kimwipes® and transferred to the other hand. The outside glove of the hand that 

held the bottle during sampling was removed. The sample bottle was sprayed with DNA 

AWAY, wiped dry with Kimwipes®, and placed in the inner Ziploc® bag. The hand that 

placed the bottle into the inner Ziploc® bag sealed the inner bag. The outer Ziploc® bag was 

then sealed with both hands, and gloves were removed. 

These steps were performed for each sample collected, and new gloves were used for each 

sample. During sampling, if gloved hands touched anything other than the sampling bottle or 

Ziploc® bag, the gloves were discarded, and the procedure was repeated. The sealed Ziploc® 

bags containing the Q-PCR samples were placed in a cooler with blue-ice and were transported 

to WESTON’s Molecular Laboratory in Carlsbad, California within the 24-hour holding time. 

One sterile field blank sample was prepared by each sampling technician during each sampling 

survey to ensure sterile techniques. The same sampling techniques were used as described above. 

For the blank, nuclease-free water was substituted for creek water. If the field blank was 

contaminated, all results for that Q-PCR set were considered invalid, and were not reported. No 

field blanks were contaminated at any time throughout this study. 

Laboratory Analysis 

Upon arrival at WESTON’s Molecular Laboratory, water samples for Q-PCR analysis were 

stored at 4ºC until being filtered within 24 hours of sampling. When performing the three-phase 

Q-PCR procedure, care was taken to avoid any contamination. All surfaces and instruments were 

first sterilized using ethanol and were then wiped again with DNA AWAY. Kimwipes® were 

used to dry the surfaces and equipment during the sterilization process. Samples collected for Q- 

PCR analysis were processed according to WESTON’s standard operating procedures for 

Bacteroides following the methods described in The Rapid Estimation of Fecal Bacteroidetes by 

the Use of a Quantitative PCR Assay for 16s rRNA Genes (Dick and Field, 2004). 

2.3.5 Chemistry Analysis 

2.3.5.1 Sample Handling and Processing 

Field scientists wearing clean, disposable gloves collected water samples in sterile, plastic or 

glass containers. During storm events, samples were collected as pollutograph samples (discreet 

grab samples taken over the course of the storm hydrograph). The dry weather event samples 

were collected as 24-hour composites. Chemistry water samples for analysis were collected from 

the horizontal and vertical center of the channel if possible. Conventional analytes were collected 

from beneath the water surface to a depth of 0.1 m. The sampling device was decontaminated 

before being moved to sample at a different station.

3.0 RESULTS 

This section presents the results of the monitoring program undertaken in SDR. The results are 

presented in the following subsections: 

• Subsection 3.1 Dry Weather Sampling 

• Subsection 3.2 Wet Weather Sampling 

Supporting data pertaining to the results sections (field data sheets and quality control (QC) 

documentation) are presented in the appendices. 

3.1 Dry Weather Sampling – April 21, 2009 

One 24-hour dry weather event was monitored on April 21–22, 2009 at two sampling locations: 

Los Coches Creek at I8 Business Route (COSDRSDR08) and San Diego River at Riverford 

Road (COSDSDR10). Forester Creek at Greenfield Drive (COSDSDR07) was not sampled as it 

was dry. Monitoring was conducted to determine the following: 

• Chemical constituent concentrations, daily loads and flux 

• The presence or absence of human fecal contamination 

• In situ field measurements of pH, DO, specific conductance, temperature and turbidity 

3.1.1 Dry Weather Chemical Constituent Concentrations 

The composite sample concentrations are presented and compared to relevant benchmarks in 

Table 3-1. Nutrient concentrations are compared between sites in Figure 3-1. Turbidity, TSS and 

TDS results are compared in Figure 3-2. 

Nutrient concentrations were generally higher at COSDSDR10 than COSDSDR08. Total 

phosphorus concentration at COSDSDR10 was above the WQO of 0.1 mg/L. Total Nitrogen 

concentrations exceeded the 1 mg/L WQO at both sampling locations. At both locations, TSS 

concentrations and turbidity were below their respective benchmarks; TDS concentrations 

exceeded the 1,000 mg/L WQO at both sites.

3.1.2 Dry Weather Microbiology Results 

The bacterial counts in grab samples (collected at approximately six-hour intervals) are presented 

and compared to relevant benchmarks in Table 3-2 In addition to FIB (i.e., total coliforms, fecal 

coliforms, enterococci, and E. coli), samples were also collected and analyzed for Bacteroides. 

At Los Coches Creek (COSDSDR08), the first sample collected (at 13:55), had the highest 

concentrations of fecal coliforms, enterococci, and E. coli for the sampling event (Figure 3-3); 

each of these parameters also exceeded their respective WQOs. Two other samples collected 

during the sampling event exceeded enterococci WQO and there were no other exceedances. 

Toward the end of the event, fecal coliform and E. coli concentrations were very similar, 

indicating a recent fecal source. Bacteroides were detected, but they were not human-specific 

suggesting that the FIB were attributable to contamination by warm-blooded animals living near 

the river rather than human contamination. 

At San Diego River at Riverford Rd. (COSDSDR10), total coliform concentrations increased 

throughout the event. Fecal coliform and E. coli concentrations showed an initial increase, 

remained relatively stable in the next three samples, and declined in the last sample. Fecal 

coliform exceeded the 400 MPN/ 100 ml WQO in only one of the five samples. Enterococcus 

concentrations exceeded the 151 MPN/100 ml WQO in all but one sample. General Bacteroides 

were detected in the first three samples collected at COSDSDR10, but no human-specific 

Bacteroides were found.

3.1.3 Dry Weather Estimated Daily Loads 

Daily loads were estimated for the one dry weather monitoring event for each drainage area 

studied and are presented in Table 3-3 (chemical constituents) and Table 3-4 (FIB). The loads are 

representative only of the monitored 24-hour period. Extrapolating beyond the event to calculate 

dry weather annual loads is not recommended because of the unknown variability in flow 

conditions throughout the year.

3.1.4 Field Measurement Results 

The field measurement results for the 24-hour non-storm monitoring event are shown on Figure 

3-5 through Figure 3-6. Field parameter results for temperature, pH, conductivity, and DO fell 

within acceptable ranges for dry weather, based on the Basin Plan objectives. There were few 

differences between the two sites, with the exception of turbidity; turbidity at COSDSDR08 

exceeded the Basin Plan objective of 20 NTU and was markedly higher than that at 

COSDSDR10 which, on the average, was below the Basin Plan objective. The water at 

COSDSDR10 was opaque and brown in appearance, whereas the water at COSDSDR08 was 

colorless and clearer. 

Dissolved oxygen (DO) is a constituent on the State Board §303(d) list for the lower part of 

SDR. The Basin Plan objective for DO is 6 mg/L. Dissolved oxygen concentrations that persist 

below this value for extended periods of time could be detrimental to aquatic life. Neither of the 

sites had DO concentrations lower than 6 mg/L over the 24-hour period monitored.

Two wet weather surveys were conducted on February 6 and December 7, 2009. Three sampling 

locations were monitored: Los Coches Creek at I8 Business Route (COSDRSDR08), San Diego 

River at Riverford Road (COSDSDR10), and Forester Creek at Greenfield Drive (COSDSDR07) 

to determine: 

• Chemical constituent concentrations, estimated instantaneous loads, and flux 

• The presence or absence of human fecal contamination. 

• In-situ measurements of pH, DO, specific conductance, temperature and turbidity 

3.2.1 Wet Weather Event 1 – February 6, 2009 

3.2.1.1 Event Summary 

The first wet weather survey was conducted at two locations only: Los Coches Creek at I8 

Business Route (COSDRSDR08) and San Diego River at Riverford Road (COSDSDR10). 

Monitoring took place from February 5, 2009 through February 7, 2009 during which time 

intermittent rainfall resulted in a total precipitation of 0.93 inches (Table 3-6). Rain began at 

16:00 on February 5, 2009 and lasted until approximately 21:00 with a total 0.16 inch 

accumulated; the resulting flow was insufficient for the purpose of monitoring. On February 6, 

2009, 0.28 inches of rain fell from 03:00 intermittently throughout the day. On February 7, 

2009, 0.49 inches of rain fell from 00:30 to 04:30.

An additional 0.63 inches of rain fell in the area after the monitoring ended and, although more 

than 12 hours passed between the end of the monitoring event and the start of the additional 

rainfall, the creeks’ water levels did not yet return to base flows. For the purpose of data 

presentation and analysis, the pollutographs for COSDSDR08 (Figure 3-7 and Figure 3-8) 

represent just the monitored storm event while the pollutographs for COSDSDR10 show the 

34



flow during the monitored storm event and, for the time period after monitoring ended, actual 

flows, and the modeled flows if no additional rainfall occurred. The storm event mean 

concentrations (EMCs) (Table 3-7, Table 3-8, Figure 3-7, and Figure 3-8) and loads (Table 3-9) 

are based on the monitored and modeled storm flows. The actual storm flow volumes are 

presented (Table 3-10) to provide a comparison regarding the entire size of the event. 

3.2.1.2 Wet Weather Event 1 Chemical Constituent Concentrations 

Wet weather samples were collected as discrete grabs over the course of the sampling event.

3.2.1.3 Wet Weather Event 1 Microbiology Results 

Bacterial concentrations and Bacteroides testing results for the first monitored storm event are 

depicted on Figure 3-8. A total of six samples were analyzed. At both locations, the 

concentrations of all four groups of FIB increased steadily with the hydrograph rise. While all 

but one sample were positive for general Bacteroides, none were positive for human-specific 

Bacteroides (Figure 3-8, inset top right of each graph). These results indicate that there was no 

recent human fecal contamination in the river during the monitored storm event.

3.2.1.4 Wet Weather Event 1 Event Mean Concentrations and Estimated Storm Loads 

An event mean concentration (EMC) of a given constituent is defined for a storm event as 

follows: 

EMC = 

Where: 

EMC – Event Mean Concentration 

Vi = discharge volume corresponding to sample i 

Ci – constituent concentration in sample i 

i = sample number 

n = total number of samples collected 

Constituent loads (M) are calculated using the following equation: 

M = 

The EMCs and loads (in kilograms) were calculated for storm event 1 and are presented in Table 

3-8 and Table 3-9.

3.2.2.2 Wet Weather Event 2 Microbiology Results 

Bacterial concentrations for the second monitored storm event are listed in Table 3-13 and 

presented graphically in Figure 3-13 through Figure 3-15. In all samples collected, concentrations 

of fecal coliforms, enterococci, and E. coli exceeded their respective water quality benchmarks. 

All samples analyzed were negative for both general and human-specific Bacteroides (Figure 

3-13, inset top right) indicating that there was no recent human fecal contamination in the river 

during the monitored storm event at any of the three sites.

5.0 CONCLUSIONS 

The current study provided needed baseline water quality data for the portions of the lower San 

Diego River watershed located within the County of San Diego jurisdiction. Three sampling 

locations were monitored, each exhibiting unique drainage area characteristics: 

- COSDSDR10 was generally ponded with a wide a flood plain and relatively low 

flow velocities, even during storm events. 

- COSDSRD08 had a narrow channel with steep sides that was influenced by 

continuous dry weather flows and relatively high flow velocities during storm 

events. 

- COSDSDR07 had flow only during storm events; its channel was narrow and 

composed of very coarse sand. 

Study results can be summarized as follows: 

• Forester Creek at Greenfield Drive (COSDSDR07) exhibited a higher sediment load than 

the two other locations monitored as it was likely influenced by the erosive sediments 

within the channel (Figure 2-3). 

• Total nitrogen and total phosphorus concentrations generally exceeded Basin Plan water 

quality objectives (WQOs) of 1 mg/L and 0.1 mg/L respectively at all sampling locations 

in storm water flows. During non storm conditions, total nitrogen WQO was exceeded at 

both locations sampled and total phosphorus WQO was exceeded at one of the two. 

• Total phosphorus and TSS concentrations increased with increased flows from storm 

water runoff at all locations monitored. The tendency of phosphorus to bind to sediment 

particles may explain these correlated increases in the concentrations of TSS and total 

phosphorus. 


(COSDSDR08 and COSDSDR10) for all chemical and microbiological constituents 

monitored. 


COSDSDR08 during the February storm for all chemical constituents except TSS; 

bacterial loads were also higher at COSDSDR10. During the December storm, organic 

nitrogen, TKN, total nitrogen, total phosphorus and E. coli loads were higher at 

CPSDSDR08. Notably, TSS loads were three times higher at CPSDSDR08 for the 

December storm while they were only slightly higher at that location during the much less 

intense February storm. As phosphorus, organic nitrogen, and bacteria may be bound to 

sediment, this would likely provide some rationale for this difference. 

• Total nitrogen and total phosphorus flux i increased with rainfall amount and intensity. 

• Non storm dissolved oxygen concentrations did not indicate low dissolved oxygen at 

either COSDSDR08 or COSDSDR10. 


conditions at both locations monitored; during storms, TDS concentrations decreased and 

increased upon return to baseflow as supported by continuous conductivity results. 

• Bacteria concentrations generally exceeded WQOs but Bacteroides testing results were 

not indicative of recent human fecal sources. 

59



• Although bacterial loads were higher during wet weather than in non-storm flows, bacteria 

flux (loads per acre) values during storms and non-storm conditions did not differ 

significantly among the monitored drainage areas.

i Flux was calculated in kilograms per acre per storm for wet weather events and in kilograms per 

acre per 24-hr period for the non-storm flow event. Therefore, flux is not reported per unit time 

as the lengths of the two storms varied (length of the first storm was approximately 50 hr while it 

was only about 10 hr for the second and the corresponding flows were monitored for different 

time periods depending on sampling location) and were not equal to the length of the dry weather 

event.
