“There are no other Everglades in the world…

They are, they have always been, one of the unique regions of the earth, remote, never wholly known. Nothing anywhere else is like them: their vast glittering openness, wider than the enormous visible round of the horizon, the racing free saltness and sweetness of their massive winds, under the dazzling blue heights of space. They are unique also in the simplicity, the diversity, and the related harmony of the forms of life they enclose. The miracle of light pours over the green and brown expanse of saw grass and of water, shining and slow-moving below, the grass and water that is the central fact of the Everglades of Florida. It is a river of grass.” Marjory Stoneman Douglas The Everglades: River of Grass (1947) They are, they have always been, one of the unique regions of the earth, remote, never wholly known.

Everglades Restoration 4 major problems facing Everglades ecosystem: Reduction in spatial extent of wetlands Degradation of water quality (e.g., phosphorus and mercury) Disruption of hydropatterns (i.e., timing, volume & distribution) Infestation by exotic plant species 4 major problems facing Everglades ecosystem: Reduction in spatial extent of wetlands Degradation of water quality (e.g., phosphorus and mercury) Disruption of hydropatterns (i.e., timing, volume & distribution) Infestation by exotic plant species

Early Everglades Restoration Activities 1972 - Florida Water Resources Act 1978 - Comprehensive Everglades ecosystem monitoring begins 1979 - Lake Okeechobee Program Interim Action Plan LOTAC recommendations 1987 - SWIM program initiated 1972 - Florida Water Resources Act 1978 - Comprehensive Everglades ecosystem monitoring begins 1979 - Lake Okeechobee Program Interim Action Plan LOTAC recommendations 1987 - SWIM program initiated

Prototype - Everglades Nutrient Removal Project August 1988 - Gov. Martinez authorized the District to build a constructed wetland 3,800 acres of prior ag land V olunteer recruitment of vegetation Design target 50 ppb Consistently reduced phosphorus to <25 ppb!

Litigation Averted! In December 1992, all parties entered into formal mediated dispute resolution July 1993 Statement of Principles – joint commitment to: end litigation, construct STAs, implement BMPs in EAA, provide funding April 1994 - Everglades Forever Act In December 1992, all parties entered into formal mediated dispute resolution July 1993 Statement of Principles – joint commitment to: end litigation, construct STAs, implement BMPs in EAA, provide funding April 1994 - Everglades Forever Act

Everglades Construction Project Initial Phase One of the largest environmental restoration programs undertaken by a public agency $720 million in acquisition, design and construction Over 42,000 acres of treatment wetlands Initial goal: 50 ppb phosphorus Performance to date has exceeded expectations! Discharges have averaged about 41 ppb Approximately 1,730 metric tons of phosphorus removed (BMPs and STAs combined) One of the largest environmental restoration programs undertaken by a public agency $720 million in acquisition, design and construction Over 42,000 acres of treatment wetlands Initial goal: 50 ppb phosphorus Performance to date has exceeded expectations!

Full Scale STA Enhancements Limerock Berm constructed in Cell 5 of STA- 1W to help redistribute flow and enhance phosphorus removal performance. Construction of the Limerock Berm was completed last summer by the Jones Company of South Florida, a 100% MBE/WBE owned firm. The Limerock Berm is about 6,900 feet long and consists of more than 22,000 tons of limerock material. The project is currently in the monitoring phase and a report documenting the performance of the Limerock Berm is to be completed in 2006.

Full Scale STA Enhancements The Limerock Berm demonstration project is being funded by a cost-share grant agreement between the District and the Florida Department of Environmental Protection. The grant funding is being provided by the U.S. Environmental Protection Agency.

Achieving Long-Term Water Quality Goals Will require additional STA enhancements Compartmentalization - hydraulic redistribution Vegetation management Operational refinements Adaptive management - incorporate results from on-going research and field observations Long-Term Plan for Achieving Water Quality Goals for the Everglades prepared by technical working group comprised of various stakeholders Will require additional STA enhancements Compartmentalization - hydraulic redistribution Vegetation management Operational refinements Adaptive management - incorporate results from on-going research and field observations Long-Term Plan for Achieving Water Quality Goals for the Everglades prepared by technical working group comprised of various stakeholders

Long-Term Plan Contains projects designed to achieve compliance with water quality standards including the phosphorus criterion in the Everglades Protection Area. In 2003, the Florida Legislature endorsed the Plan in an amended version of the EFA. Also in 2003, Plan recognized in the phosphorus rule adopted by the ERC as BAPRT. Plan was included in District’s December 2003 long- term permit application to the FDEP. Plan includes integrating with CERP project objectives and synchronizing schedules to avoid duplicative and unnecessary costs as required by the amended EFA.

Where are we today? Long-Term Plan is being implemented Design is underway for Pre-2006 Projects (STA Enhancements) with construction to start late 2004 BMP programs are being expanded Research & monitoring are progressing Projects are being integrated with CERP projects Long-Term Plan is being implemented Design is underway for Pre-2006 Projects (STA Enhancements) with construction to start late 2004 BMP programs are being expanded Research & monitoring are progressing Projects are being integrated with CERP projects
