San Diego River FY 2009-2010 WURMP Annual Report Appendices

San Diego River WURMP Annual Report Appendix A-9B
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 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.
EFFECTIVENESS ASSESSMENT
Watershed: San Diego River
ILACSD CREEK TO BAY CLEANUP SPONSORSHIP
Assess the Efficiency and Effectiveness of Sponsoring ILACSD Cleanup Efforts
to Remove Litter from Public Areas and Waterways
Management • What is the load reduction associated with sponsorship?
Questions • What is the efficiency of trash cleanup? ($/person or $/ton collected)
Targeted Measurable Load reduction due to reduction of trash (any amount) due to trash

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.
