Law enforcement in Westchester County

There are forty-five local police agencies in Westchester County, New York. In recent years, rising economic costs have spurred some smaller communities to consolidate or contract their police services with other agencies.

Westchester County Department of Public Safety

Westchester County Department of Public Safety was created in 1979 through the merger of the Westchester County Sheriff's Office with the Westchester County Parkway Police. The Westchester County Police provide primary law enforcement services for county-owned parks, parkways, and facilities. They also patrol the Town of Mount Kisco and supplement patrol along with the New York State Police for the Town of Cortlandt. The Department is the fourth largest law enforcement agency in Westchester County.

In 2010, then-Westchester County Executive Robert P. Astorino announced a plan to merge the county departments of Public Safety and Emergency Services.^[1] As of 2021^[update], these departments remain separate, and the plan appears to have been abandoned.^[2]
