The Hydrology Feature Dataset contains photogrammetrically compiled water drainage features and structures including rivers, streams, drainage canals, locks, dams, lakes, ponds, reservoirs and mooring cells. Lakes are large standing bodies of water greater than 5 acres in size. Ponds are large standing bodies of...

This dataset demarcates stands of trees (coniferous and deciduous) too numerous to plot as individual trees. The area is delineated following a generalized line along the outside edge of tree trunks. Areas are captured if at least one acre in size or of major significance especially in urban areas.

This basins dataset was created to initiate regional watershed approaches with respect to sewer rehabilitation.

This dataset demarcates the 52 isolated sub-Watersheds of Allegheny County that drain to single point on the main stem rivers. Created by 3 Rivers 2nd Nature based upon Allegheny County watershed file showing all tributaries of all streams. All tributaries draining to a single point on the river were joined as a...

The Toxics Release Inventory (TRI) data provides information about toxic substances released into the environment or managed through recycling, energy recovery, and treatment in the United States. Annual releases are compiled and reported by the U.S. Environmental Protection Agency (EPA) and shared on the TRI...

ALT’s GREENPRINT methodology involved collecting, compiling, and analyzing a vast set of available data and reports on the region’s land and water resources. GIS technology was applied to processing and integrating information in order to identify lands in Allegheny County with the greatest capacity to perform...

Greenways data was compiled by the Allegheny Land Trust as a planning effort in the development of Allegheny Places, the Allegheny County Comprehensive Plan. The plan was published in 2008.

Identifies opportunity sites throughout the A42, M29, and M16 Sewersheds for stormwater infrastructure that could fulfill both stormwater management needs and support healthy communities and neighborhoods. For more information see Green First Plan website.

From NASA's Cooperative Open Online Landslide Repository (COOLR). The Cooperative Open Online Landslide Repository (COOLR) is a worldwide database of landslide events. It currently includes NASA’s Global Landslide Catalog (GLC) and landslide events contributed by citizen scientists. In a future release of COOLR,...

Combined sewersheds in the City of Pittsburgh. Attribute field identifies sewersheds that were analyzed as part of PWSA's City Wide Green First Plan.

Identifies opportunity sites throughout the A41, O27, and M19 Sewersheds for stormwater infrastructure that could fulfill both stormwater management needs and support healthy communities and neighborhoods. For more information see Green First Plan website.

The U.S. Environmental Protection Agency provides information on the particulate matter concentration for Allegheny County that have a diameter greater or equal to 2.5 mm. The data is based on a combination of 2012 model and monitor data reported by the U.S. Environmental Protection Agency’s Office of Air and...

Data on where the Borough's storm lines, inlets/catch basins, manholes, and outfalls are located.

Parcel scale green infrastructure siting and cost effectiveness analysis. You can find more details at the project's website.
