Abstract: Per the guidance found in EC 1165-2-121, this paper provides a discussion of the effects of sea level change on the project area as well as on the restoration benefits anticipated to result from the implementation of the Central Everglades Planning Project (CEPP). The CEPP study area is shown in Figure I-1. Within the study area, the land elevation is relatively geologically static so this analysis of sea level change impacts covers only scenarios that include rising sea level conditions. The CEPP purpose is to improve the quantity, quality, timing, and distribution of water flows to the central Everglades (WCA 3 and ENP) while decreasing the magnitude and frequency of flows to the northern coastal estuaries (St. Lucie and Caloosahatchee estuaries via the C-43 and C-44). Figure I-2 shows the project components for the tentatively selected plan (Alternative 4R). The Project will increase water delivery quantities past Tamiami Trail while maintaining water deliveries to the east of the L30 and L31-N canals necessary to maintain existing levels and quality of water supply for Miami-Dade County and Biscayne Bay and decreasing water delivery via the C-43 and C-44 to improve the ecological conditions of the St. Lucie and Caloosahatchee Estuaries. Elevations in the project area range from approximately +6.0 – 0.0 feet NAVD88 with the lowest elevations in the south and along the coastline. The low elevations mean that the project area will be impacted by future sea level rise (SLR) which is projected to be 2 to 6 ft over the next 100 years. The ecosystem restoration benefits for this project are associated with the decreased frequency and magnitude of freshwater releases to the St. Lucie and Caloosahatchee Estuaries and the rehydration of freshwater wetlands and reduced salinity conditions in nearshore areas of Florida Bay downstream of Taylor and Shark River Sloughs.
