Scope

Lake County’s Lake Griffin Project:
This project required an innovative approach to stormwater master planning. Rather than spending a lot of time conducting studies, the BCI team was able to minimize study steps and accomplish rapid drainage sub-basin prioritization bases on a streamlined pollutant loading assessment method.

Outfalls were photographed and located with handheld GPS units.  Pollutant loads were computed based on land use information from GIS and a spreadsheet model using the Simple Method. Field reconnaissance was efficiently and cost-effectively implemented to allow for adjustments in sub-basin drainage divide delineations, quantification of probably runoff volume and quality (considering “closed” portions of basins and the pollutant uptake along drainage conveyance paths) as well as intensity of land use and directly connected impervious area considerations. Field truthing allowed for adjustments in pollutant load estimates and priority status of sub-basins. Conceptual water quality improvement projects were developed for the priority watersheds and projects were ranked based on pollutant load removal and cost considerations.

Cost for final design, survey, construction and O&M were computed for the priority concept projects. Priority projects were surveyed and designed for implementation in 2002/2003.

Lake County’s Lake Apopka Structure Inventory Project:
This project required BCI to locate structures and outfalls with GPS equipment. Drainage basins from past studies were checked and corrected and a GIS coverage was developed. Soils and other available GIS coverages were assembled. Historical rainfall and water quality monitoring data was collected and tabulated. Stormwater Management Systems were  located using GPS and categorized into a GIS coverage.
