Adopt Resolution to approve the Orange County Traffic Committee Report of January 16, 2025 - Item A, and establish a speed limit of 30 miles per hour on Flintridge Avenue between Sienna Parkway and Tisbury Way.

SUMMARY:

Approving the Orange County Traffic Committee Report and adopting a Resolution to establish a speed limit on Flintridge Avenue between Sienna Parkway and Tisbury Way will improve pedestrian and traffic safety.

BACKGROUND INFORMATION:

At the January 16, 2025, Orange County Traffic Committee (Committee) meeting, the following item was agendized and discussed:

Item A

Currently, Flintridge Avenue between Sienna Parkway and Tisbury Way has no posted speed limit; therefore, the statutory speed limit of 55 miles per hour (mph) applies to this roadway pursuant to California Vehicle Code (CVC) Section 22349(b).

California Manual on Uniform Traffic Control Devices (CA MUTCD) and CVC Section 22358.6(a) allow a prima facie speed limit to be established at the nearest 5 mph increment of the 85 percentile free-flowing traffic speed based on the Engineering and Traffic Survey (Survey). Also, CVC Section 22358.5 permits the option of further reducing the speed limit by 5 mph based on highway traffic and roadside condition not readily apparent to the driver. Posting a speed limit based on a Survey would allow for California Highway Patrol enforcement using radar and/or lidar detection.

OC Public Works Traffic Engineering conducted a Survey in compliance with the current CVC requirements on Flintridge Avenue from Tisbury Road to Sienna Parkway. The speed survey result shows a measured 85 percentile speed of 36 mph. The nearest 5 mph increment of 85 percentile is 35 mph along the study segment of Flintridge. However, due to existing conditions, collision history and bicycle activity, OC Public Works Traffic Engineering recommends the prima face speed limit set to be 30 mph, applying the 5 mph reduction.

The Committee recommended establishment of a 30 mph speed limit, which will result in the installation of speed limit signs along Flintridge Avenue between Sienna Parkway and Tisbury Way. The Committee unanimously approved the recommendation.

Compliance with CEQA: The proposed project is Categorically Exempt (Class 1) from the provisions of CEQA pursuant to CEQA Guidelines Section 15301, because it consists of operation, maintenance and minor alteration of existing public facilities (streets), involving negligible or no expansion of existing use.

FINANCIAL IMPACT:

Applications for the costs associated with installation of speed limit signs on Flintridge Avenue are included in Fund 115, OC Road, FY 2024-25 Budget.
