Central Florida Coordination Area (CFCA)
Portion of Central Florida within three District boundaries
Groundwater withdrawals may trigger resource constraints in adjacent Water Management District(s)
Develop a uniform water supply strategy
• Similar regulations
• Similar tools
• Similar planning

Southwest Florida Water Management District Resource Constraints
Groundwater limited in Southern Water Use Caution Area (SWUCA)
• Extensive saltwater intrusion has occurred
• Goal is to reduce groundwater withdrawals
Adopted minimum levels for lakes in central ridge area
• Immediately west of boundary with South Florida Water Management District
Upper reach of Peace River extends into CFCA
Wetland impacts from drawdown of surficial aquifer

Central Florida Coordination Area Action Plan – September 2006
3 WMD‟s Developed “Central Florida Coordination Area (CFCA) Action Plan”
• 2 Phases
• 3 Components:
• Regulatory
• Planning
• Modeling and Predictive Tools

CFCA Interim Rules
Adopted in 2007 and sunset in December 31, 2012
Effective in entire CFCA area, except SWFWMD Southern Water Use Caution Area (SWUCA)
• Groundwater allocations would be limited to a maximum of the demonstrated 2013 demand
Provides interim regulatory framework for public supply utilities and other similar applicants

Computer Modeling Component
Two models developed to simulate groundwater conditions
The East Central Florida Transient Model (SFWMD)
District Wide Regulation Model (SWFWMD)

Strategy to Enhance East Central Florida Transient Model
Identify Five (5) areas (Sites A, B, C, D, and E) in Upper Kissimmee Basin and vicinity and at each site:
• Install wells to explore multiple zones above and into the Lower Floridan Aquifer and Boulder Zone
• Conduct hydrogeologic and isotope data collection and analysis
• Install recorders/telemetry for long-term water level monitoring of new wells

Field Assessment - Indicators of Stress
Vegetation• Invasion by plants of drier communities• Presence of invasive/exotic species• Leaning/fallen trees• Dead trees or other vegetation• Shifts and changes in plant communities• Age class differences of trees• Lack of regeneration
Soils• Oxidation/subsidence• Fissuring
Hydrology• Evidence of reduced hydrology, etc.• Lack of hydrologic indicators

Planning Component
Identify:
• Future demands
• Supplemental water supply (SWS) projects to satisfy needs beyond 2013 demand
Evaluate combinations of SWS projects to best meet projected demands
Develop implementation strategies
