The Forest Preserve District's sworn police officers not only enforce federal, state and county laws but also our General Use Regulation Ordinance (PDF). The department ensures the safety of life and property in the forest preserves and adheres to the highest principles of the law enforcement profession. Officers respond to calls for emergencies, safety and service, and patrol the preserves on foot and by bicycle, ATV and squad car.

Police officers attend a state-certified police academy and 12 weeks of specialized training in conservation and Forest Preserve District ordinances, rules and regulations. Other training areas include advanced investigation, evidence, firearms, juveniles, response options and instruction. In-service training also keeps staff knowledgeable about legal updates, law-enforcement authority and human rights. Civilian personnel handle administrative duties, accreditation, and evidence, property and records management.

CALEA Certification

The Commission on Accreditation for Law Enforcement Agencies was formed in 1979. CALEA established a body of standards designed to increase a law enforcement agency's capabilities to prevent and control crime, increase effectiveness and efficiency in its services, enhance cooperation and coordination with other law enforcement and criminal justice agencies, and increase citizen and employee confidence in the goals, objectives, policies, and practices of the agency. CALEA has developed an accreditation process that provides law enforcement agencies an opportunity to voluntarily demonstrate that they meet a set of professional standards and best police practices.

The Forest Preserve District's law enforcement department is the first Illinois preserve or park district agency to meet CALEA's law enforcement accreditation standards.
