Charleston / Arastradero Corridor Project

Charleston/Arastradero Corridor

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. Among other things, it services 11 K-12 schools, several parks, shopping centers, community centers, senior living facilities, and a library. Trial striping was done on a temporary basis several years ago and will now become permanent. The final phase of 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
  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 to enhance the aesthetic quality of the corridor and treat stormwater.  
  The goals and benefits of the Charleston-Arastradero Corridor project include
""

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.

 

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.

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 Palo Avenue to Alma Street and Middlefield Road to San Antonio Road.

 

In March 2018, the City hosted two open houses for the public to view the changes and learn more about the project and construction. City staff and consultants were available to answer questions. On May 21, 2018, City Council reviewed staff’s recommendation to approve construction contracts for Phase 1 and 2 of the Charleston/Arastradero Corridor Project.


On July 14, 2018, O’Grady Paving temporarily marked the streets with proposed concrete work, so the community could drive proposed improvements on the side streets. The City has been evaluating each of the intersections and has made changes appropriate based on community feedback.

Intersections that have design changes are:

  • Terman/Donald: northeast corner of Donald will be slightly reduced
  • Pomona: bulb-outs have been reduced by a foot on both sides
  • Coulombe: bulb-out has been reduced and an addition of dedicated right turn lane onto southbound Arastradero
  • Carlson: northeast corner radius has been reduced to accommodate larger vehicles/shuttles

After further community feedback, City staff reevaluated all intersections on the project and have made the appropriate changes. This document describes the process and locations of the bulb-out modifications.
