Description: The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the <a href="http://pubs.usgs.gov/tm/11/a3"
target='_blank'><b>"Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" "Standard"</b><a>. Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

Description: 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. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.

Description: This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). 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.

Description: This data set consists of digital data describing wetlands and uplands habitats for Mobile County in South Alabama for the year 2002 and Baldwin County for the year 2001. Wetlands were classified using the Cowardin, et al., wetland classification scheme to the level of salinity modifiers. Uplands were classified using a customized classification scheme which can be cross-referenced to Anderson, et al.. The habitats were derived from interpretation of color infrared photography, mapped at 1:24,000. The Mobile County project includes all 37 USGS (7.5 minute series) quadrangles located within the county line.

Description: This data set consists of digital vector data describing the location and species composition of submerged aquatic vegetation (SAV) in coastal Alabama during summer 2015, including Mississippi Sound, Mobile Bay, Mobile-Tensaw Delta, Little Lagoon, Bay La Launch, Perdido Bay, and their communicating tributaries. The data set includes 1,068 orthophotograph frames and a MrSID mosaic produced from digital aerial imagery acquired on July 17, 18, and 19 and August 23, 25, and 26. Submerged aquatic vegetation was concentrated in upper Mobile Bay, the Mobile-Tensaw Delta, Mississippi Sound, and the Perdido Key area in southeast Baldwin County. Most of the 2015 SAV acreage occurred in the lower Mobile-Tensaw Delta, particularly in the Bridgehead Quadrangle, which contained 65% (5,905.0 ac) of the total 9,124.3 acres mapped. Other areas of substantial acreage included the Mobile Quadrangle (1,021.2 ac) in the Delta and the Grand Bay Quadrangle (414.6 ac) in Mississippi Sound. Seventy-eight percent of the total SAV acreage (7,116.7 acres) was mapped as continuous (>50%) coverage. Overall, there were 3,875.6 more acres mapped in 2015 than in the 2009 MBNEP survey, mostly due to a 2,454.7-ac increase in the Bridgehead Quadrangle and a 511.4-ac increase in the Mobile Quadrangle. Locations that had no SAV in 2009 but had substantial acreage in 2015 included areas in the Dog River, Chickasaw Creek, and West Fowl River watersheds. Of the 28 habitat categories, most were comprised of mixtures of species occurring in oligohaline systems of the study area.

Description: This data set consists of digital vector data describing the location and species composition of submerged aquatic vegetation (SAV) in coastal Alabama during fall 2015, including Mississippi Sound, Mobile Bay, Mobile-Tensaw Delta, Little Lagoon, Bay La Launch, Perdido Bay, and their communicating tributaries. The data set includes 1,068 orthophotograph frames and a MrSID mosaic produced from digital aerial imagery acquired on October 10 through 15. Submerged aquatic vegetation was concentrated in upper Mobile Bay, the Mobile-Tensaw Delta, Mississippi Sound, and the Perdido Key area in southeast Baldwin County. Most of the 2015 SAV acreage occurred in the lower Mobile-Tensaw Delta, particularly in the Bridgehead Quadrangle, which contained 63% (4,984.8 ac) of the total 7,923.1 acres mapped. Other areas of substantial acreage included the Mobile Quadrangle (929.2 ac) in the Delta and the Grand Bay Quadrangle (413.5 ac) in Mississippi Sound. 60 percent of the total SAV acreage (4,792.0 acres) was mapped as continuous (>50%) coverage. Overall, there were 1,201.2 fewer acres mapped in fall 2015 than in the 2015 summer survey. The decrease was mostly due to a 920.2-ac decrease in the Bridgehead Quadrangle and a 203.1-ac decrease in the Daphne Quadrangle. In addition to a fall decrease in the overall extent of SAV, there were changes in the proportion of patchy SAV in fall (40%) compared to the summer (22%), particularly in upper Mobile Bay and the lower Delta. Of the 28 habitat categories, most were comprised of mixtures of species occurring in oligohaline systems of the study area.

Description: The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the <a href="http://pubs.usgs.gov/tm/11/a3"
target='_blank'><b>"Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" "Standard"</b><a>. Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

Name: Baldwin County Soils 2018 - Soil Erosion Factor (Kw)
Display Field: MUName
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water.
"Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments.

Description: location and facility identification information from EPA's Facility Registry Service (FRS) for the subset of facilities that link to the Toxic Release Inventory (TRI) System. TRI is a publicly available EPA database reported annually by certain covered industry groups, as well as federal facilities. It contains information about more than 650 toxic chemicals that are being used, manufactured, treated, transported, or released into the environment, and includes information about waste management and pollution prevention activities. FRS identifies and geospatially locates facilities, sites or places subject to environmental regulations or of environmental interest. Using vigorous verification and data management procedures, FRS integrates facility data from EPA's national program systems, other federal agencies, and State and tribal master facility records and provides EPA with a centrally managed, single source of comprehensive and authoritative information on facilities. This data set contains the subset of FRS integrated facilities that link to TRI facilities once the TRI data has been integrated into the FRS database.
