City Council

The mayor of Champlin is Ryan Sabas. He serves on the Champlin City Council along with Ward 1 council member Jessica Tesdall, Ward 2 council member Tom Moe, Ward 3 council member Nate Truesdell, and Ward 4 council member Tim LaCroix.

Administration

Champlin is managed on a daily basis by the city administrator and subordinate department heads. The city administrator is Bret Heitkamp, with assistance from Shelly Peterson.

Police

The Champlin Police Department has 26 sworn officers, two community service officers, 15 police explorers, and a civilian support staff of three full-time and three part-time employees. Champlin police officers are dispatched via the Hennepin County Sheriff's Department Communication Division in Golden Valley. The police department is on the city campus at 11955 Champlin Drive.

The police department moved to the Champlin Public Safety Facility in 2008. The facility gives the department adequate space and facilities into the foreseeable future. It includes indoor parking and storage to protect police vehicles.

Fire

Champlin's fire services are provided by the joint Anoka-Champlin Fire Department. Champlin and Anoka have shared a fire department since 1985, with individual fire stations in each city. The Anoka-Champlin Fire Department moved to the Champlin Public Safety Facility in 2008. The facility has three fire truck bays and should meet the city's fire protection needs for the foreseeable future.

The fire department has 41 volunteer firefighters. Averaging 680 calls per year, the department covers 16 square miles (41 km²) with two aerial trucks, four engines, two grass rigs, two tankers, two boats, one command/rescue truck, two hazardous materials trailers, one Homeland Security truck, one ice rescue sled, and two squads.

One of the state's most traditional fire departments, the Anoka-Champlin Fire Department is distinguished by its tradition of using white vehicles, a nod to the days when Anoka firefighters used white horses to pull their steam fire engines. When motorized vehicles replaced the horse-drawn engines, the department selected white for the color of its motorized equipment.

Potential Secession from Hennepin County

On August 31, 2023, the Champlin City Council held a joint meeting with nearby Dayton to discuss both the city's potential secession from Hennepin County and into neighboring Anoka County. Champlin Mayor Ryan Sabas has said that Hennepin County has not repaid Champlin's donations to its infrastructure projects and that one-third of residents' local taxes are sent to the Hennepin County government. Sabas also cited frustration with the county not spending enough money on transportation in the community. Secession would require input from voters, and as of September 2023 has not been approved.^[10]
