| After ten years at the helm, Chief Charles Brobeck retired in 2001. By the time of his retirement, the Police Department had grown to 161 sworn officers serving a growing population of over 149,000 residents in a 49 square mile area. Chief Michael Berkow became Irvine’s third Chief of Police and instituted a comprehensive reorganization of the Department based on the concept of "geographic based policing." The goal was to bring officers into closer contact with the residents and businesses in the areas they patrol to facilitate better communication and partnerships that could lead to improving the quality of life and community safety. | |  |
