This point layer contains all the wastewater and stormwater inlets in Philadelphia with latitude and longitude coordinates.

Locations of surface water features (rivers, creeks, ponds, reservoirs) and water beneath city bridges and adjacent to city borders. Separate files are available for each waterbody (and watershed) in KML form, or as a whole in Shapefile form.

Polygon feature class representing major watersheds in Philadelphia. Data was developed originally from either USGS and the 2004 Sanborn DEM (digital elevation model) using ArcHydro watershed extraction tools. Major Watersheds are dissolved from subshed boundaries which reflect surface flow in relationship to stormwater inlets and outfalls.

Hydrographic features included in Philadelphia Hydrology Map. This map was officially adopted by City Council as the official map of Philadelphia Watercourses Designated for Protection on September 13th, 2012. The geographic data depicts watercourses within Philadelphia County as they appear on the map and will not be edited or updated. For up-to-date hydrography see the Hydrolographic_Features_Poly layer under Hydrology.

This EnviroAtlas dataset describes the percentage of forested, vegetated, and impervious land within 15- and 50-meters of hydrologically connected streams, rivers, and other water bodies within the EnviroAtlas community area. In this community, tree cover is defined as Trees & Forest and Woody Wetlands, and vegetated land is defined as Trees & Forest, Shrubs, Grass & Herbaceous, Woody Wetlands, and Emergent Wetlands. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

Philadelphia streams as mapped by Charles Ellet in 1842 and Previous study of historic streams conducted by PWD.

Point and line geometric features representing planned and completed Green Stormwater Infrastructure (GSI).

The U.S. Geological Survey (USGS), in cooperation with the Federal Emergency Management Agency, Pennsylvania Department of Environmental Protection, Pennsylvania Department of Transportation, and Susquehanna River Basin Commission, prepared hydro-conditioned geographic information systems (GIS) layers for use in the Pennsylvania StreamStats application. These data were used to update the peak flow and low flow regression equations for Pennsylvania. This dataset consists of digital elevation model rasters for each 8-digit Hydrologic Unit Code (HUC) area in Pennsylvania, one of the layer types needed to delineate watersheds within the HUC-8 areas, merged into a single dataset. The 59 HUCs represented by this dataset are 02040101, 02040102, 02040103, 02040104, 02040105, 02040106, 02040201, 02040202, 02040203, 02040205, 02050101, 02050102, 02050103, 02050104, 02050105, 02050106, 02050107, 02050201, 02050202, 02050203, 02050204, 02050205, 02050206, 02050301, 02050302, 02050303, 02050304, 02050305, 02050306, 02060002, 02060003, 02070002, 02070003, 02070004, 02070009, 04110003, 04120101, 04130002, 05010001, 05010002, 05010003, 05010004, 05010005, 05010006, 05010007, 05010008, 05010009, 05020001, 05020002, 05020003, 05020004, 05020005, 05020006, 05030101, 05030102, 05030103, 05030104, 05030105, and 05030106.

This dataset contains elevation and pebble count data for 5 new sites located at streamflow-gaging stations in the glaciated setting of Pennsylvania and southern New York. Sites were surveyed in 2016 and the elevation data represent topographic features (bankfull, thalweg, etc.) along longitudinal and cross sectional areas of stream reaches. The pebble counts were collected within each cross section. Drainage areas from StreamStats for 70 streamflow-gaging stations in Pennsylvania are also provided.
