Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Measure D3: The number of acres acquired of groundwater recharge areas critical to springs, sinks, aquifers, other natural systems, or water supply. One of the legislatively stated goals of the Florida Forever program is to acquire acres of groundwater recharge critical to springs, sinks, aquifers, other natural systems or water supply. In order to develop a means of identifying these areas, Florida Natural Areas Inventory subcontracted with Advanced Geospatial, Inc. (AGI) to develop a statewide Recharge Potential model. Input data layers for the model were consistent with those used in the Florida Aquifer Vulnerability Assessment (FAVA) developed by the Florida Geological Survey and consisted of soil hydraulic conductivity, proximity to karst features, depth to water, and overburden. These input layers were combined using a spatial analysis called Fuzzy Logic. Detailed documentation for the base model may be found in AGI's final report, "FNAI- Recharge Component, 2009". The AGI model is a statewide grid of 300 x 300m cells, with cell values ranging from 0 - 1 on a continuous scale. The continuous values allow for flexibility in how the model is applied. For Florida Forever reporting and evaluation it was necessary to group the values into several priority classes, ranging from high to low, to help focus on the most important places statewide to protect significant recharge areas. The prioritization also addresses the intent of Florida Forever to acquire recharge areas important for springs and water supply. FNAI consulted with AGI, Florida Geological Survey and DEP to accomplish this prioritization. For more details please refer to the Florida Forever Conservation Needs Assessment Technical Report, available online at http://www.fnai.org/FlForever.cfm. The final Prioritized Recharge dataset is a 15m grid with 6 priority classes. Value 1 = Priority 1 (Highest) Value 2 = Priority 2 Value 3 = Priority 3 Value 4 = Priority 4 Value 5 = Priority 5 Value 6 = Priority 6</SPAN></P></DIV></DIV></DIV>
