			<abstract>This web service depicts nearly 17,000 neighborhood boundaries in over 650 U.S. cities. Zillow created the neighborhood boundaries and is sharing them with the public under a Creative Commons license. Users of the data must credit Zillow as the data source. Additional information regarding this dataset can be found at https://www.zillow.com/howto/api/neighborhood-boundaries.htm. Note that neighborhood boundaries are not formal geographic boundaries for legal or jurisdictional purposes and should not be interpreted as such.</abstract>
			<purpose>The core mission of Shared Enterprise Geodata and Services (SEGS) is to provide a single point of ownership for geospatial datasets that are national in extent and of general use to all EPA users, and to make those datasets available through channels that best meet user needs.</purpose>
