The Comprehensive Everglades Restoration Plan (CERP)[2] provides a framework and guide to restore, protect and preserve the water resources of central and southern Florida, including the Everglades. It covers 16 counties over an 18,000-square-mile (47,000 km2) area and centers on an update of the Central & Southern Florida (C&SF) Project also known as the Restudy. The State of Florida (via the South Florida Water Management District) and the U.S. Army Corps of Engineers are undertaking various projects under CERP to help ensure the proper quantity, quality, timing, and distribution of waters to the Everglades and all of South Florida.
