RECOMMENDATIONS:
ADOPT Traffic Resolution No. 2025/4546 to establish a speed limit of 25 miles per hour (mph) on Pacifica Avenue (Road No. 5094B), which extends from Driftwood Drive (Road No. 5094A) to Port Chicago Highway (Road No. 3481C), and RESCIND Traffic Resolution No. 1970/1656, as recommended by the Public Works Director, Bay Point area. (District V)
FISCAL IMPACT:
No fiscal impact
BACKGROUND:
Pacifica Avenue is classified as a major collector roadway by the Federal Highway Administration. Such a classification requires that the speed limit be set according to standards established in the California Manual on Uniform Traffic Control Devices (CA MUTCD) and California Vehicle Code (CVC) Section 22358, if the speed limit is to be set lower than the prima facie speed limit of 55 or 65-mph. This requires an Engineering and Traffic Survey (E&TS) to be conducted to establish an appropriate speed limit.
On January 9, 2025, an E&TS was conducted according to established traffic engineering practices on Pacifica Avenue. Based on the results of the E&TS, the Traffic Engineer recommends establishing a 25-mph on Pacifica Avenue, beginning at Driftwood Drive and extending east to Port Chicago Highway.
This Board of Supervisors action will also rescind Traffic Resolution No. 1970/1656, which set the current 35-mph speed limit on Pacifica Avenue.
CONSEQUENCE OF NEGATIVE ACTION:
The existing speed limit would remain on Pacifica Avenue.
