The purpose of this layer is to show the extent of the area that allows business owners along Mount Vernon Avenue in the City of Alexandria to be able to operate businesses of certain types with an administrative approval only ( without a Special Use Permit). The following uses are permitted pursuant that the business has met the standards and procedures of section 11-5131. Restaurant up to max of 60 seats, outdoor dining up to 16 seats, amusement enterprise, outdoor food and crafts market, neighborhood outdoor garden center up to a maximum of 10000 sq. ft., and outdoor display of retail goods. Planning and Zoning staff, as well as other agencies in the city government use this layer to identify the appropriate location of the above mentioned special uses in this special overlay zone. This layer assists planning staff in approving applications and is managing compliance with all the conditions that are imposed on the business. The Overlay Zone is designed to enhance economic development and to ease in operating a business in the City of Alexandria.

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 2024. It is important to note that it is not an officially 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. Updates for the City of Mount Vernon were completed in April 2021. In 2022/2023 Westchester County conducted an outreach project to obtain updated data. The following municipalities were updated during this time: Ardsley, Dobbs Ferry, Greenburgh, Lewisboro, Mount Pleasant, North Salem, New Castle, Village of Ossining, and Peekskill. Updates for Briarcliff Manor and Buchanan were made in 2024. Buchanan has one overlay district which is an exception because no other polygons should be overlapping.
