RECOMMENDATION(S):

ADOPT Traffic Resolution No. 2017/4461 to establish speed limits on Walnut Boulevard (Road No. 7711A), and RESCIND Traffic Resolution No. 1994/3621, as recommended by the Interim Public Works Director, Brentwood area. (No fiscal impact)

FISCAL IMPACT:

No fiscal impact.

FISCAL IMPACT: (CONT'D)

BACKGROUND:

Walnut Boulevard is classified as a minor arterial roadway by the Federal Highway Administration. Such a classification requires that if the speed limit is to be set lower than the prima facie speed limit (65 mph) established by the California Manual on Uniform Traffic Control Devices (CA MUTCD) and the California Vehicle Code (CVC) Section 22358, it must be established based on an Engineering and Traffic Survey (E&TS). Based on the results of the E&TS, the Traffic Engineer recommends a speed limit of 40 miles per hour for the portion of Walnut Boulevard between the Brentwood City limit and Marsh Creek Road, and 45 miles per hour on the portion of Walnut Boulevard from Marsh Creek Road to Camino Diablo, in Brentwood. This action will allow enforcement by local enforcement agencies on Walnut Boulevard.

CONSEQUENCE OF NEGATIVE ACTION:

The local authorities power to enforce the speed limit will be limited based on criteria prescribed in the California Vehicle Code for the establishment of speed limits.
