Honorable Board of Supervisors


James C. Porter, Director of Public Works


Authorizing the Installation of Residential Speed Control Devices (3 Speed Humps) on Spring Street in North Fair Oaks, Redwood City Area; and Establishing a No Parking Zone in Broadmoor, Daly City Area



Adopt resolutions:



Authorizing the Installation of Residential Speed Control Devices (3 Speed Humps) on Spring Street in North Fair Oaks, Redwood City Area.



Establishing a No Parking Zone in Broadmoor, Daly City Area.



Commitment: Responsive, effective, collaborative government.

Goal 21: County employees understand, support and integrate the County vision and goals into their delivery of services.


The adoption of the proposed resolutions will provide for safe and orderly movement of traffic in the public right-of-way, and will better address the needs of residents, drivers, and pedestrians in the area.



A majority of the property owners on Spring Street petitioned the Department to install speed control devices as required by the Residential Speed Control Device Program (Program), see Attachment B. Traffic surveys conducted by the Department confirmed that speed control devices are warranted based on the Program criteria. Your Board previously adopted resolutions that approved the installation of speed humps on various County maintained roads.


Section 22507 of the California Vehicle Code and Section 7.28 of the County Ordinance Code allow the Board of Supervisors to establish parking zones that prohibit or restrict the stopping, parking, or standing of vehicles.



The proposed speed control devices (3 speed humps) and parking zone listed in Attachment A meet the Department of Public Works' criteria for these items. These criteria are summarized in Attachment B. Staff investigated each site to determine if it warrants additional traffic control. Property owners within 300 feet of the proposed location or the entire block, whichever was greater, were notified of the date and time of the Board’s meeting when these items will be considered. In addition, local community groups were likewise notified.


The objections and support received to date are summarized in Attachment A.


The location of parking zones on County maintained streets are currently shown on maps in the Department of Public Works, and will be made available in list form on the Department’s web site. The master lists will be updated to reflect the recommended changes if your Board approves the proposed resolution.



The cost for staff time involved in evaluating and processing requests for traffic regulations is part of the administrative cost associated with evaluating traffic-related requests involving the County maintained road system, and is financed with Road Funds. The cost to install a speed hump, warning signs, and markings varies, but is approximately $4,600 per speed hump. The cost of these speed control devices will be financed with Road Funds. The Program requires that the project proponents pay the Department an administrative fee of $400 per speed control device. We have received the fee in full. The cost of signing and/or marking parking regulations varies, but averages approximately $550 per parking zone. The cost of these speed control devices and markings will be financed with Road Funds.


There will be no impact to the General Fund.
