Progress Toward Restoring the Everglades: The Second Biennial Review - 2008
Appendix G
Interim Restoration Goals for the CERP
1. Northern Estuaries Region
1.1 American Oysters in Northern Estuaries
Increase the areal coverage of American oysters in the Caloosahatchee, St. Lucie and Loxahatchee Estuaries, and the Lake Worth Lagoon
1.2 Submerged Aquatic Vegetation in Northern Estuaries
Increase the areal coverage and improve the functionality of submerged aquatic vegetation in the northern estuaries
1.3 Flows to the Northern Estuaries
Reduce high-volume flows (monthly average flows in excess of 2,800 cfs) to the Caloosahatchee Estuary and low-volume flows (monthly flows from October to July below 450 cfs) as measured at the S-79 structure
Reduce high-volume flows (monthly average flows in excess of 2,000 cfs) to the St. Lucie Estuary and low-volume flows (monthly flows below 350 cfs) as measured using the combined flows from the S-80, S-49 and S-97 structures
Reduce high-volume flows (flows in excess of 500 cfs daily over a 7-day moving average) to the Lake Worth Lagoon as measured at the S-155 structure
2. Lake Okeechobee Region
2.1 Lake Okeechobee Phosphorus
Reduce phosphorus concentrations in Lake Okeechobee
2.2 Water Levels in Lake Okeechobee
Reduce the frequency of both harmful high water stages above 17 feet and harmful stages above 15 feet occurring for longer than 12 consecutive months
OCR for page 308
Progress Toward Restoring the Everglades: The Second Biennial Review - 2008
Reduce the frequency of harmful low stages below 11 feet
Increase the frequency of natural spring recession events, i.e., stage decline from approximately 15.5 feet in January to approximately 12.5 feet in June
2.3 Lake Okeechobee Algal Blooms
Reduce the frequency of harmful algal blooms in Lake Okeechobee
2.4 Lake Okeechobee Aquatic Vegetation
Increase the areal coverage of desirable native vegetation in Lake Okeechobee
3. Everglades Region
3.1 Water Volume
Distribute water across the ecosystem in a manner that reflects natural conditions while providing for other water-related needs of the region
3.2 Sheet Flow
Establish more historic magnitudes and directions of sheet flow in the natural areas of the Everglades
3.3 Hydropattern
Restore the natural timing and pattern of inundation throughout the ecological communities of South Florida, including sawgrass plains, ridge and slough and marl marshes
3.4 System-Wide Spatial Extent of Natural Habitat
Increase spatial extent of natural habitat
3.5 Everglades Total Phosphorus
Achieve water column phosphorus concentrations of 10 micrograms per liter in the Everglades
3.6 Periphvton Mat Cover, Structure and Composition
Restore periphyton mat cover, structure and composition that were characteristic of the spatially distinct hydroperiods (short and long hydroperiods) and low nutrient conditions in the greater Everglades wetland communities
3.7 Ridge and Slough Pattern
Restore the historical ridge and slough landscape directionality and pattern

3.8 Everglades Tree Islands
Improve tree island health and maintain healthy tree islands
3.9 Aquatic Fauna Regional Populations in Everglades Wetlands
Increase the abundance of fish to levels that approximate those predicted for pre-drainage conditions
3.10 American Alligator
Restore more natural numbers and distribution patterns for alligators across South Florida's major freshwater and estuarine landscapes
3.11 System-wide Wading Bird Nesting Pattern
Increase the total number of nesting pairs in the Everglades
Increase the percentage of wading bird pairs nesting in estuarine locations
Increase the frequency of super colony events
Establish conditions that encourage wood storks to initiate nesting earlier in winter
3.12 Snail Kite
Increase the areal extent of suitable foraging habitat for snail kites
3.13 Flows to Northern Boundaries of the Water Conservation Areas
Provide more natural surface water flows to the northern boundaries of the water conservation areas
3.14 Flows to Everglades National Park
Provide more natural surface water flows to Everglades National Park
4. Southern Estuaries Region
4.1 Salinity Patterns in Florida Bay and Biscayne Bay
Reduce the intensity, duration, frequency and spatial extent of high salinity events, reestablish low salinity conditions in mainland nearshore areas, and reduce the frequency of and rapidity of salinity fluctuations resulting from pulse releases of fresh water from canals
4.2 Submerged Aquatic Vegetation in Southern Estuaries
Reestablish a diverse seagrass community with moderate plant densities and more natural seasonality, and increase the percentage of Florida Bay having suitable habitat for seagrass growth

4.3 Juvenile Shrimp Densities in Florida Bay and Biscayne Bay
Increase densities of juvenile shrimp within the various basins of Florida Bay and Biscayne Bay
4.4 American Crocodile
Increase the frequency of salinities less than 20 parts per thousand in Florida Bay to foster optimal growth and survival of juvenile crocodiles
4.5 Florida Bay Algal Blooms
Minimize the magnitude, duration and spatial extent of algal blooms in Florida Bay
4.6 Freshwater Flows to Florida Bay
Increase freshwater flows to Florida Bay
4.7 Freshwater Flows to Biscayne Bay
Increase freshwater flows to Biscayne Bay
5. System-wide Water Volume
5.1 Quantity of Freshwater Lost to Tide
Reduce the quantity of fresh water lost to tide
6. Predicted Plan Capability
The following provides a qualitative interim goal statement for surface water storage capacity, stormwater treatment areas and wetland/natural areas restoration, along with incremental performance predictions for the end of 2010 and 2015 based on the best available information regarding: (1) project costs; (2) future federal and state budgets for the Plan; and (3) schedules for completion of Project Implementation Reports, obtaining project authorizations, and executing Project Cooperation Agreements.
Provide increased surface water storage capacity
2010—60,000 acre-feet
2015—430,000 acre-feet
Provide increased water quality treatment capacity through additional STAs
2010—5,000 acres of additional STA
2015—10,000 acres of additional STA
