BACKGROUND:
This Board has adopted similar Ordinances designating speed limits in the unincorporated areas of the County.
Section 22352.6.b of the California Vehicle Code (CVC) provides, in part, that a prima facie speed limit of 25 miles per hour exists on any highway in any business or residential district unless a different speed is determined by local authority under procedures set forth in the code.
Section 7.04.030 of the San Mateo County Ordinance Code provides in part that speed limits of 30 miles per hour are declared to exist along Alameda de las Pulgas between Camino al Lago and Harkins Avenue, inclusive of the section of Alameda de las Pulgas between Valparaiso Avenue and Harkins Avenue.
DISCUSSION:
The section of Alameda de las Pulgas between Ashton Avenue and Harkins Avenue is primarily commercial and has a posted speed limit of 30 miles per hour. Because more than half of the properties fronting the road are businesses, this segment of the road meets the definition of a business district per Section 235 of the CVC. The section of Alameda de las Pulgas between Valparaiso Avenue and Ashton Avenue is primarily residential and also has a posted speed limit of 30 miles per hour. This section meets the definition of a residential district per Section 515 of the CVC, as there are more than 16 houses or structures on both sides of the road for every 0.25 miles of roadway. The Department believes that reducing vehicle speeds along these sections of Alameda de las Pulgas can help improve bicyclist and pedestrian mobility.
The Department recommends amending Sections 7.04.025 (Speed limit twenty-five miles per hour) and 7.04.030 (Speed limit thirty miles per hour) of Chapter 7.04 (Prima Facie Speed Limits) of the San Mateo County Ordinance Code to establish a speed limit of 25 miles per hour at the following location:
1. Alameda de las Pulgas between Valparaiso Avenue and Harkins Avenue.
The County Attorney has reviewed and approved the Ordinance as to form.
EQUITY IMPACT:
The proposed lowering of the speed limits can directly improve the accessibility, mobility, and connectivity for pedestrians, bicyclists, and motorists and those that travel through the street. The lowering of speed limits may negatively impact commuters by increasing travel times for those that travel through these streets.
FISCAL IMPACT:
The staff costs for evaluating and processing requests for traffic regulations is paid for by the Road Fund as part of the administrative cost associated with evaluating traffic-related requests on the County maintained road system. The estimated cost of changing speed limit signs is approximately $600 per location, which is paid for by the Road Fund. There is no impact to the General Fund.
