Introduction Intr oduction & Ba & Backg kground ound ✓ Transtech Engineers, Inc. prepared a Citywide Engineering & Traffic Survey (ET&S) for 64 street segments in the City of San Marino since the current survey is set to expire this year. The previous Speed Survey was conducted in 2010 . ✓ The purpose of the Engineering and Traffic Survey is to establish updated speed limits that can be enforced using radar at pre-determined locations. ✓ Engineering and Traffic Survey’s are good for a maximum of 10 years . States and local agencies should conduct engineering studies at least once every 5, 7 or 10 years, in compliance with the California Vehicle Code (CVC Section 40802) to reevaluate non-statutory speed limits on segments of their roadways. ✓ Applicable sections of the California Vehicle Code (CVC) and Department of Transportation California Manual on Uniform Traffic Control Devices (CAMUTCD) , as read January 1, 2012, with updates to the CAMUTCD in March 2019 have been followed so that the posted speed limits can be upheld by the courts and do not constitute a "Speed Trap" as defined by CVC Section 40802. 2
