City of La Quinta
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 fourteen 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 fourteen 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)(II)]. 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 fourteen (14) street segments that were part of the 2014 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 14 years (to November 19, 2028)
from the effective date of the particular ETS conducted for the following street segments:
• Avenida Bermudas from Avenue 52 to Calle Arroba 40 miles per hour
• Avenue 50 (Eastbound) from Jefferson Street to West MVCC Limit 45 miles per hour
• Avenue 50 (Eastbound) from West MVCC Limit to East MVCC Limit 50 miles per hour
• Avenue 50 (Eastbound) from East MVCC Limit to Madison Street 50 miles per hour
• Avenue 52 from Desert Club Drive to Washington Street 50 miles per hour
• Avenue 52 from Washington Street to Jefferson Street 50 miles per hour
• Blackhawk Way from Adams Street to Dune Palms Road 35 miles per hour
• Eisenhower Drive from Calle Sinaloa to Avenida Bermudas 40 miles per hour
• Fred Waring Drive from Washington Street to Jefferson Street 50 miles per hour
• Highway 111 from West City Limit to Adams Street 45 miles per hour
