CERP Project:
Florida Keys Tidal Restoration

Since the Restudy, various studies and other projects have refined this project's scope. This project will provide for the removal of approximately 0.6 miles of impediments and will restore an historic flow way between the Atlantic Ocean and the Gulf of Mexico which was blocked during the construction of US Highway 1. An existing tidal creek restoration project near the proposed restoration project was fully successful.

One tidal creek near Marathon, Florida has been selected for restoration. Culverts to maximize flow will be located, sized, and placed under U.S. 1 between Fat Deer Key and Long Point Key (MM56) to allow tidal exchange and flushing. Monitoring of water quality, benthic community composition, and sediment particle size will be performed before construction, at six months, and one year after construction completion. Additional tidal flow way restoration projects will be subsequently identified based upon the results.
