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.

Engineering and Traffic (Speed Zone) Survey
The City’s Engineering and Traffic Survey (often referred to as a Speed Zone Survey) is the approved and governing document for speed limits on all City Streets. The Study is conducted by a licensed Traffic Engineer in compliance with guidelines contained in the latest versions of the California Vehicle Code and the California Manual on Uniform Traffic Control Devices. The Traffic Engineering Study is submitted to City Council for approval and adopted via passing of a City Ordinance. The approved Speed Zone Study is distributed to the Sheriff’s Department for their use in enforcement of speed limits.
