CITY COUNCIL
DATE:November 3, 2015
TO:
Honorable Mayor and City Councilmembers
FROM:
Christopher L. Foss, City Manager
SUBJECT:
Emergency Road Maintenance on Tassajara Road
Prepared by Andrew Russell, City Engineer
EXECUTIVE SUMMARY:
The City Council will consider the authorization of funds associated with emergency repair work
necessary for Tassajara Road.
FINANCIAL IMPACT:
The estimated cost to repair the roadway is approximately $235,000 and would be funded using
Gas Tax dollars.
RECOMMENDATION:
Staff recommends that the City Council approve a budget change, authorize the use of Gas Tax
funds for the emergency repairs to Tassajara Road and authorize payment to Toll Brothers, Inc.,
for the maintenance work.
Submitted By Reviewed By
Public Works Director Assistant City Manager
DESCRIPTION:
Public Works staff inspected a segment of southbound Tassajara Road near Moller Creek.
During the inspection, staff identified a 560-foot long segment of southbound roadway that had
settled, resulting in severe longitudinal cracks and differential settlement within the travel lane.
Additionally, Staff identified voids in the roadway embankment at the Moller Creek culvert. The
voids were adjacent to existing soldier pier retaining walls and seem to be a result of erosion
from storm water runoff and potentially also from vibrations due to roadway traffic. The Public
Works Director determined that repairs needed to be completed as soon as possible to prevent
further damage or the possibility of losing portions of the southbound travel lane. Such further
damage may have resulted in an unplanned closure of Tassajara Road.
Public Works staff solicited qualifications and quotes from area developers and contractors. Toll
Brothers Inc. with their contractor, RGW Construction Inc., responded with a quote for the work.

Since Toll Brothers was working within the area and their contractor had the necessary
equipment and expertise, Staff directed them to proceed with the emergency repair work. Staff
estimates the cost of the repair work to be approximately $235,000.00. Toll Brothers will be
reimbursed based on actual time and materials used to make the repairs. The repair work
began Thursday, October 22 and is anticipated to be competed the first part of November 2015.
The Public Works Director authorized Toll Brothers to make the repairs to Tassajara Road. The
emergency repair work includes: crack filling; grinding and installing geotextile fabric; asphalt
concrete repairs; backfilling voids in the roadway embankment, installing soldier piles and wood
lagging retaining walls, shoring, backfilling, installing an asphalt curb; and installing visqueen
and sand bags to winterize the slope.
The costs associated with the repair work on Tassajara Road will be paid from the Gas Tax
Fund.
NOTICING REQUIREMENTS/PUBLIC OUTREACH:
The Contractor placed portable message signs at each end of the work area to alert drivers of
the work and potential delays. Staff spoke with Quarry Lane School and two adjacent
homeowners associations to inform them of the urgent maintenance work and possible related
travel delays. Information about the work was also posted on the City of Dublin website and
sent to Public Works “Notify Me” subscribers.
