BACKGROUND
• Per State Law, speed limits are generally recertified every 7 years • Speed limits may be extended (14-yrs from date of original certification) • San Leandro’s most recent evaluation was completed in 2017 • Since the last update, changes in State Law were enacted, namely AB 43 & AB 1938 which created more flexibility to lower speed limits. 2 WHY ARE LOWER
SPEEDS DESIRED?
3 SPEED LIMITS ARE SET BY STATE LAW
CALIFORNIA VEHICLE CODE (CVC)

• By default speed (Prima Facie)

85th percentile speed: Most drivers
(85%) are traveling at or below this
speed. Speed Limits are usually set
near this speed.
Pace Speed: The 10-MPH range which
contains most of the vehicles. In nearly
all cases, the speed limit should be set
within the Pace Speed.
EXAMPLE: Lewelling Blvd
(Wicks Blvd to Sedgeman St)
85th Percentile Speed
PACE
8 E&TS PROCESS
**Cannot set a speed limit that is less than 12.4 mph from the 85th Percentile Speed.
Measure prevailing speeds
Identify the 85th percentile and round to the nearest 5-mph increment Determine whether street qualifies for any optional one time 5-mph reductions.
Example factors are:
• Higher than average crash rate
• “condition not readily apparent to a driver”
• Adjacent to pedestrian or bike generating land use
Starting June 30, 2024, streets within a Safety Corridor may apply additional optional 5-mph reduction. 9 PRELIMINARY RECOMMENDATIONS
