Description
This project is in response to a FY2010 cooperative funding project request from Polk County to alleviate localized
flooding and improve water quality in the Garden Grove Pines subdivision. The existing stormwater collection system
is inadequate to convey the stormwater runoff from the 80 acre drainage basin. The project proposes retrofitting the
existing storm sewer system and the construction of a 2.5 acre wet detention pond for treatment and attenuation. The
stormwater system will be upgraded with a gravity pipe system which will route the stormwater system to a stormwater
pond. The proposed stormwater pond will be constructed on a 3.0 acre parcel of land that formerly served as a
wastewater treatment facility that the County is proposing to purchase. The pond will discharge through a control
structure to an existing wetland system for polishing, then eventually to the Lake Florence outfall ditch.
Benefits
The Garden Grove Pines Stormwater Retrofit project will provide treatment of an 80 acre urban drainage basin that
currently provides little water quality treatment and additional storage for the reduction of localized flooding.
Costs
The total project cost is $400,000, with Polk County and the District each contributing half ($200,000). District funds
shown in the table include staff salaries.
