The Draft Supplemental 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 June 18, 2015.
The Decomp Physical Model is a field-scale test that is being conducted along a 3,000-foot stretch of the L-67A and L-67C levees and canals in Water Conservation Area (WCA) 3A and 3B to determine how best to design and formulate plans for future decompartmentalization of WCA-3, as envisioned in the Comprehensive Everglades Restoration Plan (CERP).
Installation of the DPM was completed in October 2013. The first operational testing period was conducted from November – December 2013, and the second operational testing period was conducted from November 2014 – January 2015.
The Corps is proposing a third year of testing in 2015, with the potential for a fourth year of testing in 2016, to gain information to further address scientific, hydrologic and water management uncertainties that require clarification prior to the design of decompartmentalization features within WCA 3, included in CERP.
Water flow, stage, sediment movement, water quality, and ecological parameters will be measured during each operational test cycle.
