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

PWD Parcels with fields added that help categorize parcels by Green Stormwater Infrastructure (GSI) Planning program and standardize ownership or ownership category and summarize impervious cover by surface type.

Locations from the NYC Green Infrastructure initiative which presents an alternative approach to improving water quality that integrates “green infrastructure,” such as swales and green roofs, with investments to optimize the existing system and to build targeted, cost-effective “grey” or traditional infrastructure.

This dataset contains the locations and detailed information of green infrastructure practices in NYC neighborhoods built primarily through NYC Green Infrastructure Program initiatives. Green infrastructure (GI) collects stormwater from streets, sidewalks, and other hard surfaces before it can enter the sewer system or cause local flooding. The GI practice data contained in this dataset includes the location, program area, status, and type of GI. This dataset is updated by the NYC Department of Environmental Protection on a monthly basis. The "Medians" polygon layer contains large-scale green infrastructure practices within City-owned medians to target water quality objectives and inland flooding challenges.

Stormwater, wastewater, and drinking water data from a variety of sources is being compiled. Stormwater data has (is) been collected for many urbanized town and village centers statewide. Wastewater data is available for some towns and is currently being developed more fully as data becomes available. Drinking water data is rarely available. Point, line, and polygon data was collected and compiled through field observations, municipal member knowledge, ortho-photo interpretation, digitization of georeferenced town plans and record drawings, and state stormwater permit plans. Accuracy of all data is for planning purposes and field verification is at the users discretion. Subwatershed Drainage systems were mapped to establish the connectivity of the stormwater features, and to show where runoff from impervious surfaces in various subwatersheds within an urbanized area eventually enters the receiving water. Subwatershed boundaries were drawn by hand using a variety of elevation data and corelated to each towns Stormwater Infrastructure report.

This data has been collected as part of a larger project by the City of Austin's Watershed Protection and Development Review Department to inventory its drainage infrastructure and create a GIS to store this information. The project includes an internal team developing a GIS based on record documents and an external team locating ground level appurtenances using GPS field collection units. The data in this data set represents the former.
