Westchester County


Image of hand sketching a map of Westchester CountyThe Department of Planning consists of a team of professionals dedicated to promoting orderly development that protects and improves the quality of life and physical environment of Westchester County. The department works with a wide array of citizen boards to carry out its work.

We hope you will explore our varied projects and resources. The subjects range from protecting water quality and natural habitat to advancing housing opportunities, promoting smart growth and reviewing development proposals. We also provide extensive census and research data and information on local zoning codes.

If you are interested in fair and affordable housing and want to be notified of available or upcoming offerings of affordable homes or rental apartments, the county highlights opportunities on the Homeseeker Web page.

What's New at the Department of Planning? 

Westchester’s Soil and Water Conservation District announced the recipients of its first annual Soil and Water Conservation Achievement Award, which recognizes activities and projects, that promote conservation, restoration and sound management of soil and water resources in Westchester County. An awards ceremony will be held December 11 at the Westchester County Center.

Planning staff is working with Parks, Recreation and Conservation staff and the Watershed Agricultural Council (WAC) on a research-oriented, forest regeneration pilot project to install deer exclusion fencing around a half-acre wooded area at the County’s Hilltop Hanover Farm property.

A comprehensive GIS update of local zoning districts has been completed. Several years in the making, this new data layer reflects current zoning district boundaries in all 43 Westchester municipalities.

Housing provides funding to assist in the development of new fair and affordable housing as well as the rehabilitation of existing housing stock. We also provide affordable housing and rental assistance to homeowners and tenants who are income eligible.

The county, working in concert with each municipality, addresses its local housing needs, as well as its share of regional affordable housing deficits. Learn more

Watershed Protection
There are six major drainage basins in Westchester - Upper Hudson River, Croton River, Lower Hudson, Upper LI Sound, Bronx River, and Lower LI Sound.

Watershed protection is a major concern so the county oversees a variety of programs to protect county water quality. These reservoirs provide drinking water for residents of Westchester, NYC and Connecticut while others rely on wells. Learn more
