Pedestrian Crossing at Charleston and Arastradero Intersection

Project Description

The 2.3-mile Charleston-Arastradero Corridor is a heavily used, residential- arterial road, serving as an east-west connector for the southern section of Palo Alto. The corridor services 11 K-12 schools, several parks, shopping centers, community centers, senior living facilities, and a library. The project includes the installation of landscaped medians, curb extensions/bulb-outs, enhanced bicycle and pedestrian improvements, and traffic signal modifications consistent with the existing striping/roadway configuration.

Scope of Work

  • Enhanced safety for K-12 students walking and biking to school and other corridor users;
  • Smoother traffic flow along the corridor;
  • Beautification of the streetscape; the project will add approximately 80 trees, shrubs, groundcover, grasses, and bioretention plants throughout the 37,000 square feet of landscaped elements.

Scope of Work (expanded)

The overall objective of the project is to address the needs of nearby residents and the surrounding community who have requested an improved corridor with more moderate vehicle speeds, safer conditions, and various vegetation improvements will be used to enhance the aesthetic quality of the corridor and treat stormwater.

Landscaped medians will improve safety for pedestrians, bicyclists, and other motorists from users making abrupt lane changes and dangerous turns. Pavement markings will help a driver’s awareness of pedestrians and bicyclists. To further protect bicyclists, the corridor will have a dedicated or buffered bike lane. More details on the streetscape improvements included in the project can be in the project FAQs(PDF, 2MB).

Another key component of the Charleston-Arastradero Corridor Project is the upgrade of traffic signal equipment for increased controllability of signals. An adaptive traffic control system will also be implemented as a part of this project. It will optimize signal timings which will improve traffic flows. In addition to traffic signal modifications, a new traffic signal will be installed at Louis/Montrose and E. Charleston Road.

The Charleston-Arastradero project has been in the works for almost 15 years with significant stakeholder outreach and community engagement. The City Council approved the concepts for the corridor in 2015, and the Architectural Review Board approved the landscape plans in 2017. Federal grants fund part of the project, which requires a phased construction approach. Phase 1 includes the corridor section Arastradero Road between Foothill Expressway to Clemo Avenue. Phase 2 includes corridor section of West Charleston Road from Alma Street to Middlefield Road. Phase 3 of construction will be the remaining sections of the corridor between Los Palos Avenue to Alma Street and Middlefield Road to San Antonio Road. 

 

Project Status 

The Charleston-Arastradero Corridor Project – Phase 3 is currently in the stage of finalizing project plans and obtaining an encroachment permit from Caltrans for the planned work at the El Camino Real intersection. Construction of Phase 3 is anticipated to start Spring 2021.
