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.

What's new at the Department of Planning? 

In June, the Board of Legislators approved the Saw Mill River-Pocantico River Watershed Reconnaissance Plan, prepared by staff of the Planning and Public Works departments as part of County Executive Robert P. Astorino’s efforts to assist municipalities through a regional approach in addressing flooding problems.

Nominations are being accepted for the first annual achievement awards of the Westchester County Soil and Water Conservation District. The awards will recognize activities and projects which promote the conservation, management and restoration of soil and water resources in Westchester.

A ribbon-cutting for Comstock Heights, a development of 14 Affirmatively Furthering Fair Housing townhouses in the Village of Briarcliff Manor, was held on June 19. The two-bedroom, 1,100 square feet affordable duplex condominiums are on North State Road.

Planning staff is working on the “Planning Base Studies” for the Town of North Castle. One of the County’s shared services initiatives, the Department’s support helps expedite the local comprehensive plan process and lowers the costs for municipalities.

Westchester 2025 aims to provide a solid foundation for constructive conversation about maintaining our quality of life and how to work together on shared goals. Learn more

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
