School Speed Limit Sign Installation Project

  • Project typeTraffic and Transportation

Project Description

During the summer of 2021, the City of Palo Alto is proceeding with the installation of speed limit signs in school zones to meet speed limit restrictions of 20-miles-per-hour to comply with updated state law and the City’s municipal code requirements establishing speed zones in Palo Alto. This supports student safety and reduces high traffic speeds in and around schools.

The City Council adopted the ordinance in accordance with Assembly Bill (AB) 321 and California Vehicle Code (CVC) Section 22358.4(b)(1) to designate 20-miles-per-hour posted speed limit zones within 500 feet of school grounds while students are going to or leaving the school, either during school hours or during the noon recess period on designated streets.

Scope of Work

Within Palo Alto, there are 16 public schools and 11 private schools. The Office of Transportation staff conducted a signage review and prepared plans for the installation of the school zone and speed limit signs in accordance with the California Manual of Traffic Control Devices.

 Various examples of school zone and speed limit signs

The combination of the school zone and speed limit signs will be installed in the school areas of Palo Alto. The number of signs planned to be installed citywide exceeds 250 signs and will require installation of approximately 150 new posts. Every effort was made to utilize all existing posts where feasible to reduce the number of new signs posts citywide. The project plans to utilize all but about 15 existing posts which will be removed. These signs are placed within the planter area when available or behind the sidewalk when the sidewalk is contiguous with the curb to the extent feasible in the City’s right of way.

Here is a sample of a signage plan:
