Name: FDEP State funded Hazardous Waste Cleanup Sites
Display Field: NAME
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: The State-Funded cleanup program is designed to address sites where there are no viable responsible parties; the site poses an imminent hazard; and, the site does not qualify for Superfund or is a low priority for EPA. Remediation efforts are triggered when a Florida Dept. of Environmental Protection District Office requests adoption of a site for state-funded cleanup. Funding for these remedial efforts comes from the Water Quality Assurance Trust Fund. Remedial activity may include contamination assessments, risk assessments, feasibility studies, design and construction of treatment systems, operation and maintenance of the installed treatment systems, and removal of contaminated media when necessary.
Description: Regulated Facilities from STCM (Storage Tank Contamination Monitoring).This coverage includes facilities with registered above-ground or underground storage tanks. This dataset contains both currently and previously regulated facilities. It also contains facilities registered with DEP for the purpose of tracking on-site petroleum contamination.
Description: What is a Subsidence Incident? Sinkholes are closed depressions in areas underlain by soluble rock such as limestone, dolostone, gypsum, or salt. Sinkholes form when surface sediments subside into underground voids created by the dissolving action of groundwater in the underlying bedrock. Other subterranean events can cause holes, depressions or subsidence of the land surface that may mimic sinkhole activity. These include subsurface expansive clay or organic layers which compress as water is removed, collapsed or broken sewer and drain pipes or broken septic tanks, improperly compacted soil after excavation work, and even buried trash, logs and other debris. Commonly, a reported depression is not verified by a licensed professional geologist to be a true sinkhole, and the cause of subsidence is not known. Such an event is called a subsidence incident. The Florida Geological Survey maintains and provides a downloadable database of reported subsidence incidents statewide. While this data may include some true sinkholes, the majority of the incidents have not been field-checked and the cause of subsidence is not verified.

This layer identifies locations where FDOT roads cross/abut water drainage flowlines such as stream/river, artificial path, etc. This layer is used in the EST for the notification tool. For source dates, inputs, and parent/child relationships see metadata.
Description: This data set contains Florida's designated Wild & Scenic Rivers. This layer depicts national wild and scenic river segments designated by Congress and the Secretary of the Interior, as well as state wild and scenic river segments designated by the State of Florida. "Wild" rivers are free of dams, generally inaccessible except by trail, and represent vestiges of primitive America. "Scenic" rivers are free of dams, with shorelines or watersheds still largely primitive and shorelines largely undeveloped, but accessible in places by roads. "Recreational" rivers are readily accessible by road or railroad, may have some development along their shorelines, and may have been dammed in the past. Data for national wild and scenic rivers were provided by the U.S. Forest Service and come from a variety of sources including the US Forest Service, National Park Service, Bureau of Land Management and the Fish and Wildlife Service. Spatial data for national rivers were referenced to the latest High Resolution National Hydrological Data Layer (NHD 1:24,000 Scale or better), published by United States Geological Survey (USGS). State wild and scenic river data were obtained from High Resolution National Hydrological Data flowlines (NHD 1:24,000 Scale or better), originally published by United States Geological Survey (USGS) and modified by the NHD data steward for Florida (FDEP).
Description: This dataset contains Nationwide Rivers Inventory (NRI) data for the State of Florida. The Nationwide Rivers Inventory (NRI) is a listing of more than 3,200 free-flowing river segments in the United States that are believed to possess one or more "outstandingly remarkable" natural or cultural values judged to be at least regionally significant. Hence, NRI river segments are potential candidates for inclusion in the National Wild and Scenic River System. Under the Wild and Scenic Rivers Act section 5(d)(1) and related guidance, all federal agencies must seek to avoid or mitigate actions that would adversely affect one or more NRI segments.

Description: This dataset contains the Florida subset of the National Waterway Network, which is a comprehensive network database of the nation's navigable waterways. The nominal scale of the dataset varies with the source material. The majority of the information is at 1:100,000 with larger scales used in harbor/bay/port areas and smaller scales used in open waters.
Name: NHD(24K) Linear Surface Water Drainage Network
Display Field: GNIS_NAME
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: This data set contains routes that make up a linear surface water drainage network. This is the fundamental flow network consisting predominantly of stream/river and artificial path vector features. It represents the spatial geometry, carries the attributes, models the water flow, and contains linear referencing measures for locating events on the network. Additional NHDFlowline features are canal/ditch, pipeline, connector, underground conduit, and coastline. The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The data was originally published by the USGS then it is modified by the NHD data steward for Florida (FDEP). When received from FDEP, this data was originally in geodatabase format. When in shapefile format the data loses the network functionality of the geodatabase. Please contact the FDEP if you need the original geodatabase.
Name: NHD(100K) Linear Surface Water Drainage Network
Display Field: GNIS_NAME
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: This data set contains regions representing areal NHD hydrographic landmark features. One of the more important is the stream/river feature. It represents the aerial extent of the water in a wide stream/river with a basic set of attributes. They typically contain NHDFlowline artificial paths that are used to model the stream/river. Artificial path carries the critical attributes of the stream/river, whereas NHDArea represents the geometric extent. The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. Medium resolution NHD is based on the content of the U.S. Geological Survey (USGS) 1:100,000-scale Digital Line Graph (DLG) hydrography data, integrated with reach-related information from the U.S. Environmental Protection Agency Reach File Version 3.0 (RF3). The FDEP is the NHD data steward for Florida. When received from FDEP, this data was originally in geodatabase format. When in shapefile format the data loses the network functionality of the geodatabase. Please contact the FDEP if you need the original geodatabase.
Description: INSTITUTIONAL CONTROL REGISTRY (ICR) An institutional control site is a site that has certain restrictions on the property. For example, a site may be cleaned up to satisfy commercial contamination target levels. An institutional control may be placed on that property indicating that it may only be used for commercial levels. If the owner of the property ever wants to use that property for residential purposes, the owner will have to ensure that the contamination meets residential target levels.
Description: This data set contains Brownfield Boundaries. Brownfields are defined by the Florida Department of Environmental Protection (FDEP) as abandoned, idled, or underused industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination. The primary goals of Florida's Brownfields Redevelopment Act (Ch. 97-277, Laws of Florida, codified at ss. 376.77-.85, F.S.) are to reduce health and environmental hazards on existing commercial and industrial sites that are abandoned or underused due to these hazards and create financial and regulatory incentives to encourage redevelopment and voluntary cleanup of contaminated properties. A 'brownfield area' means a contiguous area of one or more brownfield sites, some of which may not be contaminated, that has been designated as such by a local government resolution. Such areas may include all or portions of community redevelopment areas, enterprise zones, empowerment zones, other such designated economically deprived communities and areas, and Environmental Protection Agency (EPA) designated brownfield pilot projects. This layer provides a polygon representation of the boundaries of these designated Brownfield Areas in Florida.
Description: This data set represents springsheds for St Johns River Water Management District (SJRWMD). A variety of different modeling techniques were used to derive these polygons. This data was originally downloaded in 10 different shapefiles from SJRWMD and merged into one layer. A unique metadata existed for each shapefile. This metadata is a combination of all metadatas. For more detailed information on each springshed it is recommended that you reference the original layers metadata from SJRWMD.
Description: This dataset contains Outstanding Florida Springs (OFS) located in the State of Florida. Section 373.802(4), Florida Statutes (F.S.), defines "Outstanding Florida Springs" or OFS to include all historic first magnitude springs, as determined by the department using the most recent Florida Geological Survey springs bulletin, and the following additional six springs: DeLeon, Peacock, Poe, Rock, Wekiva, and Gemini. OFS do not include submarine springs or river rises. There are 30 OFS springs consisting of 24 historic first magnitude springs and the 6 named additional springs. While the statutory definition includes the spring runs associated with these springs and spring groups, this coverage identifies the WBIDs associated with the OFS spring vents.
Description: This dataset contains Springs Priority Focus Areas located in the State of Florida. As per the Florida Springs and Aquifer Protection Act (part VIII of chapter 373, Florida Statutes), the department delineates priority focus areas for each Outstanding Florida Spring that is impaired by excessive nutrient pollution. Using the best data available, the department delineates the priority focus areas considering groundwater travel time to the spring, hydrogeology, nutrient loads in the springshed, and other factors. The priority focus areas are adjusted to rely upon understood and easily identifiable boundaries such as roads or political jurisdictions. The priority focus areas become effective upon incorporation into a basin management action plan (BMAP).
Description: This data set contains indexes and Esri shape files of boundaries of the designated sole source aquifers and related aquifer boundaries. Data provide a vector polygon GIS layer showing available materials representing extents at the land surface related to 78 designated Sole Source Aquifers (SSA) related to announcements in the Federal Register. GIS coverages for SSAs were obtained from EPA Regions 1, 2, 3, 4, 5, 6, 8, 9, and 10 for a baseline period in September of 2009. Each SSA polygon was checked against the Federal Register (FR) determination for that SSA. These coverages were appended, in order to create a national seamless coverage of SSAs. There are 89 GIS polygons for the Sole Source Aquifers, since in addition to a single SSA designated area polygons, some Regions have delineated GIS layers for streamflow zones, aquifer recharge areas, and other features at the land surface important for the SSA designations. GIS materials are not available at this time for the St. Joseph SSA in Indiana [53 FR 23682 (1988)].
Description: This map layer contains the shallowest principal aquifers of the state of Florida portrayed as polygons. The map layer was developed as part of the effort to produce the series "Ground Water Atlas of the United States". The published maps contain base and cultural features not included in these data. This is a replacement for the July 1998 map layer called Principal Aquifers of the 48 Conterminous United States created by the U.S. geological Survey.
Description: This dataset contains a statewide polygon layer identifying the Waterbody Identification Units (WBIDs) on the Strategic Monitoring Plan that the department has scheduled to be monitored to determine whether waterbodies and waterbody segments are attaining the minimum criteria for surface waters established in the Surface Water Quality Standards (Chapter 62-302, F.A.C.) and the Identification of Impaired Surface Waters (Chapter 62-303, F.A.C.). The WBIDs or assessment units are drainage basins, lakes, lake drainage areas, springs, rivers and streams, segments of rivers and streams, coastal, bay and estuarine waters in Florida. Monitoring efforts have been prioritized in specific basins to allow there to be a focus on collecting data where there may be shortfalls, and to combine with critical ongoing sampling needed for assessment. Following data collection, sample results are uploaded to Watershed Information Network (WIN) or the state biological database (SBIO). Waterbodies assessed as impaired are placed on the Verified List of Impaired Waters and are prioritized for a TMDL (Total Maximum Daily Load) to be developed to determine the maximum amount of a pollutant that a waterbody can receive and attain water quality standards. For more information or questions regarding waterbodies identified on the Strategic Monitoring Plan, please contact Kevin O'Donnell (kevin.odonnell@dep.state.fl.us or (850) 245-8469).
Description: Outstanding Florida Waters, (OFW), are waters designated worthy of special protection because of their natural attributes. This special designation is applied to certain waters, and is intended to protect and maintain existing acceptable quality standards. The OFW layer is a GIS spatial dataset that represents the OFW boundaries throughout the state of Florida. This project involves adding new data to and modifying existing data within the OFW data layer for better accuracy and representation. Boundaries for Outstanding Florida Waters (OFWs) as described in Section 62-302.700, F.A.C. This layer includes all three types of OFWs: OFW Aquatic Preserves, Special OFWs, and Other OFWs.
Description: Aquatic Preserves are state-owned sovereign submerged lands in areas which have exceptional biological, aesthetic, and scientific value, as described in Chapter 258.39, Florida Statutes, which have been set aside for the benefit of future generations. These areas are managed by the Florida Department of Environmental Protection's Office of Coastal and Aquatic Managed Areas. Currently, all Aquatic Preserves are also Outstanding Florida Waters (OFWs). However, it is important to note that there are three Aquatic Preserves whose OFW boundaries differ from the Aquatic Preserve boundary. These are described more specifically in the OFW rule 62-302.700: Indian River - Malabar to Vero Beach - does not include portions of Sebastian and Turkey creeks; Wekiva River - does not include portions of the St. Johns River; and Big Bend Seagrasses - the OFW rule specifies certain "incorporated and unincorporated areas" that are excluded from the Aquatic Preserve.
Description: The Unified Reef Map is a regional map of benthic habitats that occur throughout the Florida reef tract. The Unified Reef Map consists of individual maps and monitoring data provided by our numerous partners. The purpose of the Unified Reef Map is to provide a comprehensive view of habitats from Martin County through the Florida Keys to the Dry Tortugas. The Unified Reef Map supports the larger effort to coordinate scientific research and promote a reef-wide approach for protecting Florida’s reef tract. To create the URM, individual maps are integrated, data are edited where overlapping or neighboring maps disagree, and habitat classes are cross-walked to allow comparisons between maps. The URM symbolizes benthic habitats, or bottom types, using the Unified Classification (UC) system. The UC framework allows translation between different classification schemes while retaining the original detailed information provided by our mapping partners. There are five hierarchical UC classes starting at UC Level 0 which represents broad habitat classes and can be consistently translated between individual maps. At the most detailed UC Level 4, benthic habitats are described differently between map providers and may differ throughout the Unified Reef Map. The UC system is also cross-walked to the Coastal and Marine Ecological Classification Standard (CMECS). Un-edited source maps provided by URM map partners are also available. The Unified Reef Map is a living map and will be updated as new data become available. For more information visit: http://ocean.floridamarine.org/IntegratedReefMap/UnifiedReefTract.htm. For source dates and inputs see metadata.
Description: This is a subset of the layer LU_L3_STATE, created by using the definition query "FLUCCS >= 6000 and FLUCCS < 7000" to select out wetlands. This dataset is an inventory of Land Uses and Land Covers classified in the State of Florida. The dataset has been derived from data created by the five Water Management Districts and the Florida Department of Environmental Protection's Bureau of Watershed Restoration. The land use and land cover classification level 3 code is defined by the Florida DOT's FLUCCS classification system. This dataset represents land use and land cover information derived from imagery. Land use and land cover information provides environmental scientists an understanding of the relationships between human activities, land surface physiography and water resources. This layer was created by merging the source data layers with priority given to the most recent data. For source dates and inputs see metadata.
Description: This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the State of Florida. This data set consists of geo-referenced digital data and associated attributes created in accordance with the "FGDC Proposal, Version 1.0 - Federal Standards For Delineation of Hydrologic Unit Boundaries 3/01/02"(http://www.ftw.nrcs.usda.gov/huc_data.html). Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type of watershed, non-contributing areas and flow modification. Arcs are attributed with the highest hydrologic unit code for each watershed, linesource and a metadata reference file.

Description: This data set is a complete digital hydrologic unit boundary layer to the Watershed (10-digit) 5th level for the State of Florida. The Watershed Boundary Dataset (WBD) defines the areal extent of surface water drainage to a point, accounting for all land and surface areas. Watershed Boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. The intent of defining Hydrologic Units (HU) for the Watershed Boundary Dataset is to establish a base-line drainage boundary framework, accounting for all land and surface areas. At a minimum, the WBD is being delineated and georeferenced to the USGS 1:24,000 scale topographic base map meeting National Map Accuracy Standards (NMAS). Hydrologic units are given a Hydrologic Unit Code (HUC).

Description: This data set contains regions representing areal NHD hydrographic landmark features. One of the more important is the stream/river feature. It represents the aerial extent of the water in a wide stream/river with a basic set of attributes. They typically contain NHDFlowline artificial paths that are used to model the stream/river. Artificial path carries the critical attributes of the stream/river, whereas NHDArea represents the geometric extent. The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The FDEP is the NHD data steward for Florida. When received from FDEP, this data was originally in geodatabase format. When in shapefile format the data loses the network functionality of the geodatabase. Please contact the FDEP if you need the original geodatabase.
Description: This data set contains regions representing areal NHD hydrographic waterbody features. Basic waterbodies such as lake/pond features are represented here. They portray the spatial geometry and the attributes of the feature. These water polygons may contain NHDFlowline artificial paths to allow the representation of water flow.

Description: This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.
