The New River and Upper Hillsborough River Watershed is approximately 121 square miles in southern Pasco County and northern Hillsborough County, Florida. The Southwest Florida Water Management District (SWFWMD) and Pasco County retained ECT to update the watershed management plan (WMP).
Specifically, ECT revised the existing ICPR model to include peer review comments and adjacent watershed inflows. Efforts included model modifications to sub-basins and structures within Hillsborough County, which were obtained from the Hillsborough River HCSWMM watershed model. ECT developed floodplain delineations and limits based on the revised model output.
ECT conducted a revised level of service (LOS) analysis to identify critical flood-prone locations within the watershed. Best management practices and cost estimates were designed to reduce flooding conditions within the watershed. Our team also updated the WMP report, figures, and geographic information system (GIS) GWIS geodatabase.
