Description: This layer identifies corporate boundaries for all 45 municipal jurisdictions in Westchester County. Coverage originally obtained from New York State Office for Real Property Services (ORPS), and has been substantially modified to better align with current municipal tax parcel boundaries (WCparcels) based on a compilation of 2012 municipal tax parcel datasets. As all of Westchester's town's and cities compile their tax parcel databases independent of one another, there are situations were the tax parcels do not line up at the municipal borders, often resulting in gaps or overlaps of tax parcels at the border areas. This update sought to re-align boundaries to best follow the municipal boundaries as defined by the tax parcels, and often involved making the best possible spatial compromise where there were gaps or overlaps in tax map jurisdictions. It also reflects the 2011 municipal boundary change that resluted from the annexation of a tax parcel from the Town of Mount Pleasant to the Town of New Castle.
Description: Data was last processed on February 2017. This layer represents 2016 tax parcel polygons in Westchester County. It was assembled from collection of tax parcel assessment information of 25 different municipal jurisdictions. Assessment data is from ORPTS. NOTE: Overlaps and gaps do exist between municipalities due to the fact that each municipal assessment jurisdiction maintains their own data.

Description: This file contains polygon data representing service areas that are part of public water supply systems within Westchester County, New York, based upon geographic data in GIS or CAD format provided by water supply systems and integrated into a common countywide feature class in 2012. Not all areas in the county served by public water supply systems are covered, and the accuracy of the geographic representations and attributes included in this dataset is dependent upon the accuracy of the source data, which has not been independently verified by Westchester GIS .
Description: This data layer represents a compilation of local zoning districts and is based on zoning information compiled and digitized from each of Westchester's 43 municipalities between 2011 and 2016. It is important to note that it is not an offically adopted map of local zoning, but rather a depiction - or "snapshot" - of local zoning at the time of compilation. As such, this data layer is intended to be used for general reference purposes only. Since local zoning is constantly subject to change, inquiries regarding current status of local zoning districts, zoning designations of specific parcels, and exact use and bulk requirements should be verified at the local level by contacting the local planning or municipal clerk’s office. Selected updates were completed for this data layer in 2015 and 2016 for the municipalities of Rye City, Town of North Castle, Village of Mamaroneck and Port Chester.

This is NOT official Postal Service data.
