Out of the 64 segments surveyed and based on the San Marino 2020 Engineering and Radar Speed survey results, it was determined that the speed limits on
the following four (4) segments justify reduction in the posted speed limits.
The following 4 street segments are recommended for their speed limits to be reduced as follows:

Per Section 2B.13 CAMUTCD: Reduction of 85th Percentile Speed by Justification of an Engineering and Traffic Study and Approved by Civil or Traffic
Engineer as follows:
Option 1: For cases in which the nearest 5 MPH increment of the 85th percentile speed would require a rounding up, then the speed limit may be rounded
down to the nearest 5 MPH increment below the 85th percentile speed, if no further reduction is used. CVC Section 21400(b).
Option 2: The posted speed may be reduced by 5 MPH from the nearest 5 MPH increment of the 85th-percentile speed, due to road conditions and land use in
compliance with CVC Sections 627 and 22358.5.
Option 3: The posted speed may be reduced by 5 MPH from the nearest 5 MPH increment of the 85th-percentile speed, due to higher than expected collision
rates, road conditions and land use in compliance with CVC Sections 627 and 22358.5.
