Since its incorporation in 1960, the unprecedented growth of San Dimas has transformed the City from an essentially rural area to a well-balanced community offering industrial, commercial, and residential living. In addition to the 1,700 acre Frank G. Bonelli Recreational Area which lies within the City boundaries, there are many parks such as San Dimas Canyon Park, a city-owned golf course (San Dimas Canyon Golf Club), and over 27 miles of equestrian trails for riding. The city services include an extensive recreational program for youth and for senior citizens, and the City boasts a new modern City Hall, with excellent provisions made for County Sheriff and Fire Departments, along with a fine Los Angeles County Library and Engineering Regional Office.

CAL FIRE Releases Updated Fire Hazard Severity Zone Maps for San Dimas
On March 24, 2025, CAL FIRE released updated Fire Hazard Severity Zone (FHSZ) maps for Local Responsibility Areas (LRAs), including San Dimas. These maps are based on the latest fire science and help guide local planning, construction standards, and emergency preparedness efforts.
The City has 120 days from the release date to review and consider adoption. Staff is currently evaluating the updated designations in coordination with the Los Angeles County Fire Department.
Insurance Note:
While many residents have questions about fire insurance, CAL FIRE’s maps are not used by insurance companies to set rates or determine coverage. According to the California Department of Insurance, insurers rely on their own wildfire risk models. State regulations outline wildfire safety actions, like defensible space and home hardening, that may be factored into how insurers assess risk.
