On behalf of the resident homeowners' association, Taylor Engineering performed an assessment of the Sawgrass stormwater system to determine its ability to manage stormwater runoff, maintain acceptable water quality, and provide flood control; and to develop basin management recommendations to reduce sediment and pollutant loading and potential flooding. The system, experiencing significant shoaling and water quality problems, comprises 100+ interconnected lakes discharged by two pump stations to serve the exclusive 2,400-acre Sawgrass community.
The assessment involved data collection, field measurements, and personnel interviews to develop a base understanding of system functionality and key operational parameters; application of the Advanced Interconnected Pond Routing Program to simulate the system's response to 25- and 100-year, 24-hour rainfall events; and off-site investigations to identify nutrient loading sources. The findings from a preliminary assessment provided the basis for a recommended multiphase approach to quantify system capacity, identify flood control improvements, and to maintain acceptable water quality.
