Dear Mr. McKinney:
As requested, Willdan has completed a review of the recommended speed zones on one
segment in the City of La Quinta. The Engineering and Traffic Study dated January 5,
2017 is hereby amended to include the updated speed limits for this segment identified
below that supersede the previous speed limit recommendations.
1- Adams Street — Darby Road to Fred Waring Drive
We are pleased to submit the enclosed recommendation and supporting documentation
for the above segment. The Engineering and Traffic Survey for the above segments was
conducted in accordance with applicable provisions of the CVC, following procedures
outlined in the California Manual on Uniform Traffic Control Devices (California MUTCD)
dated November 2014, and as required by Section 627 of the California Vehicle Code.
The Report is intended to satisfy the requirements of Section 40802 of the CVC to enable
the continued use of radar for traffic speed enforcement.
We appreciate the opportunity to serve the City of La Quinta and the assistance and
cooperation afforded to us during the course of this study.
Very truly yours,
