Project Overview

ATM is providing a detailed third party review on behalf of Seminole County of the Lake Jesup PLRG/TMDL and the construction of the three component models (HSPF, EFDC, WASP) under development by the St. Johns River Water Management District (SJRWMD) and the Florida Department of Environmental Protection (FDEP).

This work was initiated with a detailed peer review of the HSPF watershed model, the EFDC model and the WASP water quality model for the Lake Jesup PLRG. Independent simulations were performed to evaluate model execution and to assess model calibration. ATM ran simulations using the HSPF, EFDC and WASP models and provided subsequent recommendations to SJRWMD and FDEP to improve the construction and calibration. ATM is continuing active coordination with FDEP during the continuing development of the models to ensure the final TMDL model is technically defensible and useful as a tool for BMAP allocations
