High Quality Successional and Native Forests of Tallahassee and Leon County, Florida. This feature class was created as part of the Environmentally Sensitive Areas (ESA) Mapping Project.The Native and High Quality Successional Forests were mapped in GIS as part of a larger Environmentally Sensitive Areas (ESA) mapping project, which was a collaborative effort between the city and county growth management departments, the planning department and TLCGIS. This project was driven out of a need for better data that was standardized county-wide to support environmental resource planning, protection and regulation, etc. It was also needed to support public works and emergency management. Additionally, the Tallahassee-Leon County Comprehensive Plan Conservation Element Objectives and Policies required compilation and maintenance of maps of conservation and preservation features, effective 1990--the same year that the GIS Interlocal office was created. Prior to this in 1988, the original ESA data layers were mapped by environmental professionals and stormwater engineers working in what was then called the Leon County Department of Public Works. The data was drawn onto USGS quad maps (base) using mylar overlays (scale 24,000)--drainage basins were also mapped. It was supported by a Department of Community Affairs grant, and there was assistance from the FSU Geography Department. The Native and HQS Forests were identified using DOT Vegetation Inventory Maps, USFS Soils and Vegetation maps, some aerial photo review, and ground truthing.In 1996 a proposal was brought to the GIS Executive Committee by the departments as an ESA Remap Project that would map the layers (also Greenways) at larger scales of 1,200 and 2,400 using the new GIS base map. The project was funded by the TLCGIS. The layers were mapped by OPS environmental/biology students and graduates with oversight by the departments.Native and HQS Forests originally mapped on the quad maps were then heads up digitized into the GIS using base map data and two sets of digital aerial photos from '94 & '96. Hard copy aerials from '37 and '76 were also used for comparison. In the southeastern US mixed hardwood/beech-magnolia forests have a fairly distinct spectral signature on the false color infrared imagery which staff learned and were trained to recognize, with ground truthing where possible (property owners were called for access). The upland pine/longleaf and pine oak hickory signatures were not as easy to identify. The goal of the ESA Remap was to identify forests that had been continually forested since at least '37 (less so for longleaf forests where bulk of the diversity is in the groundcover). The soil and contour layers, with the aerials were used to find additional areas that hadn't been previously mapped. So, essentially it was a process of identifying a specific signature and also the environmental conditions (soils, slope, aspect, topography) that would have supported or allowed a forest type to have been protected throughout history. For example, beech-magnolia forests are often found on steep slopes that were historically difficult to access for logging or around wetland/floodplain areas that would have potentially limited logging due to saturated soils. Florida Natural Areas Inventory Element Occurrence data and Florida Fish and Wildlife Conservation Commission Closing the Gaps data were also used.

This layer depicts potential Karst features in Tallahassee and Leon County, Florida. This layer is displayed with 45% transparency by default. This layer was developed using a 2012 LiDAR derived DEM. In 2012, the water table in Leon County was significantly lower that normal allowing for a better surface analysis of potential karst features.What is Karst and why is it important? Karst Waters InstituteKarst is a special type of landscape that is formed by the dissolution of soluble rocks, including limestone and dolomite. Karst regions contain aquifers that are capable of providing large supplies of water.More than 25 percent of the world’s population either lives on or obtains its water from karst aquifers. In the United States, 20 percent of the land surface is karst and 40 percent of the groundwater used for drinking comes from karst aquifers.Karst features in Leon County are most fundamentally occur in depressions in the landscape. By delineating these depressions and analyzing their geomorphic characteristics, karst features can be mapped and classified according to their morphology. The process of identifying, delineating, and classifying karst features in Leon County is described below:Prepare Sink Depth Raster1: Fill sinks in countywide 2012 DEM (This DEM was used because the water table was exceptionally low in 2012.)2: Subtract original DEM from filled DEM to produce output raster of sinks with their depthsPrepare Contour data set to be used for forming Sink Polygons1: Create Z-negative 2-foot contours starting 1.5 feet blow the top of the sink. Smooth resulting contours2: Convert closed contours to polygons3: Merge polygons into multi-part features and explode into individual single-part polygons for each depressionPrepare classified Potential Karst polygons1: Eliminate polygons created from systematic noise in the Lidar-derived DEM2: Review remaining polygons features and assign feature attributes based on geomorphic characteristics. The karst feature types were assigned based on the classification system published by the Florida Springs Nomenclature Committee Report: FGS Special Publication 52

Environmentally sensitive areas mapping NHW (Normal High Water) for waterbodies in Tallahassee and Leon County, Florida. These features are updated with imagery, digital elevation models (Lidar), and field observations on and as needed basis. While some waterbody features like stormwater ponds are not considered environmentally sensative, they have been inincluded in this set of features as reference and because they do participate in the drainage sytems of Tallahassee and Leon County. Methodology: The initial data source was the original waterbody data from the 1988 ESA maps. Additionally, Hydro features Type=215 from 2009, 2012, and 2015 Landbase datasets are added. The newly added waterbodies are examined to determine if they normally hold water by comparing aerial photography. Sources used as reference for the delineation process are the 2009 DEM, 2012 DEM, and the 2015 DEM, Leon County Soil Survey, National Wetlands Inventory (NWI) features which have Water1 attribute classifications of F, G, or H, 1996 Additional data sources include , USGS Digital Ortho Quarter Quadrangle imagery, orthoimagery from 1996, 2009, 2012, and 2015, permit files, and field verification. All polygon features are attributed and assigned a confidence interval. 4=walked boundary; 3=field verified, 2=sources agree, 1=sources disagree. Confidence intervals can change as a result of further investigation. Supplemental Information Waterbody features were obtained through remote sensing and topographic analysis. Site specific study needed to verify the normal high water line.

This data set is intended to provide members of the Tallahassee/Leon County GIS Interlocal community with layer content to use in their maps, projects and business processes. It identifies land areas that are known to have had changes that may be of concern when considering future development. The Department of Planning Land Management & Community Enhancement (PLACE) of Leon County Florida, while collaborating with the Leon County Development Support and Environmental Management (LCDSEM) and Tallahassee - Leon County GIS (TLCGIS), has been tasked with the gathering and collating all available disturbed land locations. The data is derived from a DEP point layer to identify locations of landfills in addition to mandatory Non-Phosphate site locations which were initially based on a parcel cadastral data set. The polygon-based feature class was digitized to reflect the disturbed area on parcels by reviewing aerial photography from various years while comparing the current digital elevation model (DEM).
