San Antonio Landscape, Median & Road Improvement Project - Phase II

Project Update October 2012:
In order to minimize traffic impacts during daytime hours, striping of the recently repaved San Antonio Road is scheduled for the nights of October 10 – October 12 between the hours of 9 PM and 6 AM. The striping and adjustment of utility valves this week will complete the resurfacing phase of the San Antonio Road improvements.

The next and final phase of the project will include the landscape improvements, which is scheduled to be completed in November 2012.  For more information about this Capital Improvement Project (Phase II of the San Antonio Road Median Improvement Project Update), visit www.cityofpaloalto.org/sa or call 650-329-2295.

If you have specific questions about this night time work, please contact Elizabeth Ames, Senior Engineer, at (650) 329-2502.

Project Update September 2012:  The City is nearing completion of the road reconstruction phase of the San Antonio Road Median Improvement Project. The curbs, gutters, sidewalks and driveways have all been repaired and the contractor will now grind off the existing asphalt and repave the street. Expect traffic delays and use alternate routes if possible during work times.

The planned repaving schedule for San Antonio Road between Middlefield Road and Highway 101 is as follows:

Monday, 9/24:           Grind existing asphalt (9 AM - 4 PM)
Tuesday, 9/25:          Grind existing asphalt (9 AM - 4 PM)
Wednesday, 9/26:     No major work planned
Thursday, 9/27:         Repave westbound San Antonio at night 
                                   (9 PM Thursday night to 6 AM Friday morning)
Friday, 9/28:              Repave eastbound San Antonio at night 
                                   (9 PM Friday night to 9 AM Saturday morning)

(This major construction will be followed by resetting utility valves and manholes,
installation of new signage and striping, and installation of new irrigation and landscaping.)

August 2012: 
On August 13, construction will begin on additional road and median improvements at the intersection of San Antonio Road and Middlefield Road as part of the road work included in Phase II of the San Antonio Road Median Improvement Project.  To minimize disruption during commute hours, all traffics lanes will remain open until 9 AM and reopen again by 4 PM.

This phase of the construction will include widening southbound San Antonio Road in order to add an additional left turn lane onto Middlefield Road. After the road is widened and road base repairs are completed, the existing street will be ground down and repaved with new asphalt. The final striping will be installed seven to ten days after paving.

After the road rehabilitation is completed, the irrigation system, new trees and landscaping will be installed.

This project replaces aging infrastructure along San Antonio in the median island and the sidewalk planting strips.  Construction began in November 2011 and will last approximately one year.  The limits of work are from Highway 101 to Middlefield Road.

May 2012:  Soil removal, tree removal and stump grinding has been completed.  Street light and irrigation conduit has been installed.

The next phase of the project will begin in May 2012.  This includes sidewalks, medians and landscaping, in addition to the roadway itself.  Lane closures will begin on Tuesday, May 15 going west-bound on San Antonio Road between Middlefield and Highway 101.  The new phase of the project includes replacement of concrete medians, sidewalks, curbs, gutters, driveway aprons and improving the intersection of Middlefield and San Antonio by adding a west-bound left-turn lane.  There will be frequent lane closures on San Antonio between 9:00 am and 4:00 pm Monday through Friday,  but at least one lane will remain open in each direction at all times. Following the concrete work, the roadway and intersections will be repaved with new asphalt. The final phase will be the landscaping and tree planting within the medians, anticipated to begin this Fall.

This project will replace aging infrastructure along San Antonio between Highway 101 and Middlefield Road.  The San Antonio Landscaping and Median Project – Phase I, from Middlefield Road to Briarwood Way was completed in 2009.   This second phase will complete the entire San Antonio corridor.

Construction began in November 2011 and last approximately one year. Work will include:  tree removal, sidewalk replacement, repair and replacement of deteriorating curb, installation of new more sustainable street trees, plant material and irrigation in the medians and sidewalk planting strips and resurfacing of the street.  On-street parking will not be allowed in the construction area.    

This project will provide a long term solution that will prevent problems associated with tree roots, improved road surface for vehicular and bicycle travel, reduce costly on-going road repairs and provide an aesthetic median planting to complete the San Antonio corridor.
