SUPPLEMENTAL ENVIRONMENTAL ASSESSMENT & PROPOSED FINDING OF NO SIGNIFICANT IMPACT AVAILABLE FOR PUBLIC & AGENCY REVIEW- June 28, 2017

The Supplemental Environmental Assessment (EA) and Proposed Finding of No Significant Impact (FONSI) for the Decomp Physical Model (DPM) is now available for public and agency review. Comments will be accepted through August 27, 2017.

Installation of the DPM was completed in October 2013. Four operational testing periods have been conducted within the October through January timeframe in 2013, 2014, 2015, and 2016. The Corps is proposing operations in 2017 year-round, with the potential for additional years of testing through 2021 to gain information to further address scientific, hydrologic and water management uncertainties that require clarification prior to the design of decompartmentalization features within Water Conservation Area-3, included in the Comprehensive Everglades Restoration Plan (CERP). Water flow, stage, sediment movement, water quality, and ecological parameters will be measured during each operational test cycle.
