DATE: March 3, 2026
TO: Honorable Mayor and City Councilmembers
FROM: Colleen Tribby, City Manager
SUBJECT: Green Stormwater Infrastructure Project, CIP Project No. ST0121,
Contract Change Order Authorization and Budget Transfer
Prepared by: Vatsal Patel, Assistant Public Works Director/City Engineer
EXECUTIVE SUMMARY:
The City Council will consider approval of a resolution increasing the contract change order
authority of the City Manager by $50,000 to compensate the contractor, Suulutaaq, Inc., for
needed sidewalk improvements related to the Green Stormwater Infrastructure Project, CIP
Project No. ST0121. To fund the increased costs, the City Council will also consider a budget
transfer of $50,000 in Transportation Development Act funds available in the Citywide Bicycle
and Pedestrian Improvements Project, CIP No. ST0517.
STAFF RECOMMENDATION:
Adopt the Resolution Approving Contract Change Orders W ith Suulutaaq, Inc. for the Green
Stormwater Infrastructure Project, CIP Project No. ST0121, and approve the budget change.
FINANCIAL IMPACT:
The sidewalk improvements add $50,000 to the Green Stormwater Infrastructure Project in
eligible Transportation Development Act (TDA) costs. Staff recommends a budget transfer
from the Citywide Bicycle and Pedestrian Improvements Project, CIP No. ST0517, to allocate
$50,000 in available TDA funds to the Dublin Green Stormwater Infrastructure Project for this
purpose. There is no impact to the General Fund.
DESCRIPTION:
On June 25, 2024, the City Council adopted Resolution No. 67-24 awarding a construction
contract of $2,501,546 to Suulutaaq, Inc. for the Green Stormwater Infrastructure Project, CIP
Project No. ST0121 (Project), and authorizing the City Manager to approve change orders up
to a contingency amount of $250,000 for a total potential construction contract amount of
$2,751,546.

The Project is under construction and approximately 90% complete. The contractor has
completed grading activities, bioretention basin construction, storm drainage, pathway paving,
fencing, and sidewalk enhancements along Amador Valley Boulevard. Remaining activities
include final planting and landscaping maintenance, punch list corrections, and final closeout.
The current contact change order amount of $250,000 will be utilized during closeout on a
handful of unforeseen conditions that were identified through construction of the Project. These
include:
Presence of a set of fiber optic lines that was discovered in the same alignment of the
proposed storm drain system, which required additional excavation to expose the fiber
optic lines prior to the installation of the storm drain piping into the bioretention basin;
Location of Kinder Morgan high pressure gas lines that required a revision of the plans
to include raising and re-aligning the storm drain pipe upstream, beyond the Project
limits, to meet the required clearance for such lines;
Additional grading and installation of an overside drain into the bioretention basin
needed to manage erosion caused by offsite runoff accumulation from the wet weather
in late fall of 2025; and
Presence of a 15-inch storm drain that required exposure and potholing to determine if it
was still active or could be abandoned.
In addition, certain sidewalk improvements totaling approximately $50,000 were needed on
Amador Valley Boulevard in the vicinity of the Project and were added to the contractor’s
scope. The cost of this additional work is eligible for reimbursement through TDA funds
allocated to the City by the Metropolitan Transportation Commission in September 2024.
These funds were awarded for various bicycle and pedestrian improvements, including
sidewalk improvements at Amador Valley Boulevard, and are currently sitting in the Citywide
Bicycle and Pedestrian Improvements Project, CIP No. ST0517 .
The budget transfer of $50,000 to the Green Stormwater Infrastructure Project, in addition to
approval of an increase to the City Manager’s contract change order authority, will allow for
completion of the Project for a total construction contract cost of $2,801,546.
