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? 

The Planning Department received the National Association for County Community and Economic Development 2014 Award of Excellence in the “Affordable Housing” category at the 39th Annual NACCED Conference, held in September in Arlington County, Virginia.

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.

The U.S. Census Bureau plans to release the 2013 American Community Survey one-year estimates on September 18. It will provide new sample data on thousands of topics for geographies with populations of 65,000 or greater, including the cities of Mount Vernon, New Rochelle and Yonkers, the town of Greenburgh and Westchester County as a whole

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
