Dear Larson Justice Center / County of Riverside Superior Courts,
California Vehicle Code Sections 40801 and 40802 require Engineering and Traffic Surveys (ETS) to
establish or revise prima facie speed limits on certain streets within a local jurisdiction before law
enforcement can utilize radar or other electronic speed measuring devices for speed enforcement. These
surveys must be updated every five, seven, or ten years to ensure the speeds reflect current conditions as
dictated by the California Vehicle Code. The surveys can be extended from 5 to 7 years provided the
City's police officer(s) have completed a 24-hour radar operator course [CVC 40802(c)(2)(B)(i)(I)].
Additionally, some surveys may be extended to ten years if the City Traffic Engineer certifies there have
been no significant changes to the roadway segment(s) or traffic conditions [CVC 40802(c)(2)(B)(i)(Il)].
- These provisions assure that posted speed limits are kept reasonably current.
This letter is to certify that I am the licensed and duly designated Traffic Engineer for the City of La
Quinta. I have evaluated the thirty six (36) street segments that were part of the 2007 ETS and
determined no significant changes have occurred, including, but not limited to, changes in adjoining
property or land use, roadway width or traffic volume for these street segments. Therefore, based on the
above reasons, the most recent Engineering and Traffic Survey may be extended up to 10 years from the
effective date of the particular ETS conducted for the following street segments:
• Adams Street from Fred Waring Drive to Miles Avenue .............................45 miles per hour
