Description
This project involves the engineering design, permitting, and construction of a stormwater treatment system within the
southwest basin of Lake Parker, the most urbanized basin draining to Lake Parker. Earlier studies completed for Lake
Parker indicated that this basin discharges high pollutant loads into the lake. This project will build upon previous City
and District efforts in this problematic basin. The first treatment system was constructed at the lake shore or
downstream portion of this drainage basin (Lake Parker Southwest Outfall Retrofit, P742), and included a large system
of baffle boxes to stop sediments and trash from reaching the lake. This project will focus on the upper reaches of the
watershed and will provide much needed attenuation of stormwater upstream of the previously completed project. This
upstream project will provide significant pollutant load reductions and will increase the effectiveness of the first
completed treatment system. The long-term benefits of the project include a reduction in the loading of sediments,
trash, and nutrients to Lake Parker.
Benefits
The design will include components that will reduce peak flows through storage and release and provide water quality
treatment through attenuation of stormwater. This project will significantly enhance the treatment efficiency of the
previously completed project along the lake shore (P742). The project will treat stormwater in a 595 acre sub-basin
that drains to Lake Parker.
Costs
The total project cost for design, permitting, land acquisition and construction is $3,765,550. The FY2005 cost for
design and permitting is $125,000. The Peace River Basin Board has approved funding in the amount of $62,500 in
FY2005 while the City will fund the remaining $62,500. The prior funding shown in the table below includes a feasibility
study completed in FY2004. The Peace River Basin Board contributed $42,600 while the City contributed $42,600 for
the FY2004 study. The Peace River Basin Board has budgeted $336,725, $470,863 and $187,632 respectively in
FY2007, FY2008 and FY2009. The City will contribute $336,725, $470,863 and $470,863 respectively in FY2007,
FY2008 and FY2009. In FY2010 the City requested the Peace River Basin Board fund $683,440 while the City will
fund $683,440. Due to budgetary constraints the Peace River Basin Board only included $200,000 in its FY2010
budget for this project. The District funding amounts shown in the table include staff salaries, travel and central garage
charges.
Additional Information
Lake Parker is listed as an impaired waterbody by the Florida Department of Environmental Protection. The need for
treating stormwater from this basin was identified in the Lake Parker Diagnostic Feasibility Study published by the
District and the City of Lakeland in 1993. The 595-acre sub-basin on the southwest portion of Lake Parker is highly
urbanized and was shown to be a major source of pollutant loading in the Study. Annual loading of total nitrogen (TN)
and total phosphorus (TP) from this basin is 3,970 Kg and 998 Kg, respectively. This represents 10% and 12% of the
total external loading to the lake of TN and TP, respectively. A BMP evaluation of this basin was completed in FY2004
(Project K857) and identified four retrofit sites in which wet detention ponds could be constructed. The FY2005 project
currently underway will design and permit the retrofit sites identified in the FY2004 BMP evaluation. The design and
permitting is contingent upon the City acquiring the land for these projects.
