The Police Department/Service District came into existence in 1990.  Homeowners voted to create the Service District, which is managed by a Board comprised of seven Black Butte Ranch homeowners, who are appointed by the Deschutes County Board of Commissioners. The Service District Managing Board has staffed the Police Department with six full-time officers, which includes a Chief of Police, a Sergeant, and four Officers. The Administrative Assistant takes care of general office work and accounting responsibilities. The Department provides the Ranch with 24-7 patrol and other law enforcement services. The Department is also involved in crime prevention, disaster mitigation, and planning in cooperation with the Ranch Management and residents to preserve the safety, security and tranquility of the Ranch. Sworn department personnel are certified police officers and function as such out of, and within the District boundaries.
