The Engineering Department is responsible for handling all issues related to traffic in the City of San Dimas.

Traffic Counts and Speed Survey

Traffic Counts- The Engineering Division is responsible for maintaining current traffic counts on arterial and collector streets. Traffic counts are generally updated every two years.

Speed Survey- Speed limits on City streets are updated approximately every five years.  The Engineering Division works closely with the Police Department to perform an engineering and traffic survey and update speed limits based on the results. 

Sewer Information

The City's sewers are maintained by Los Angeles County Consolidated Sewer Maintenance District.  The County's Annual Report provides information on how to avoid an expensive sewer back up, as well as contact information and background on the division.

To provide a consistent, statewide regulatory approach to address the issue of sanitary sewer overflow (SSO), the State Water Resources Control Board (State Water Board) adopted Statewide General Waste Discharge Requirements (WDRs) for Sanitary Sewer Systems, Water Quality Order No. 2006-0003 (Sanitary Sewer Systems WDR) on May 2, 2006. The Sanitary Sewer Systems WDR requires public agencies that own or operate sanitary sewer systems to develop and implement sewer system management plans and report all SSOs to the State Water Board's online SSO database.

The City's Sewer System Management Plan (SSMP) can be viewed through the links below.  Hard copies and copies of the attachements may be viewed upon request at City Hall. 

If you have any questions or concerns regarding the sewer please contact the City of San Dimas Public Works Department at (909)394-6240.  For emergencies, contact the Los Angeles County Consolidated Sewer Maintenance District directly at 800-675-HELP(4357).
