Subject: Request for Increased Regional Arterial Program Funding for the Dune
Palms Road Bridge Spanning the Whitewater River
Dear Mr. Kirk,
The City of La Quinta respectfully requests the Coachella Valley Association of
Governments (CVAG) approve Amendment No. 2 to the Agency Reimbursement
Agreement between the City of La Quinta and CVAG for the Design and Construction
of a new Bridge over the Whitewater River on Dune Palms Road increasing the
Regional Arterial Program Funding Contribution for the new Bridge from $1,506,750
to $5,395,230, an increase of $3,888,480. It also requests Amendment 2 extend
the term of the Agency Reimbursement Agreement through December 2024.
CVAG previously authorized and obligated the following:
Original Reimbursement Agreement, dated 12-03-2003 $1,506,750
Amendment 1, Dune Palms Road Widening, dated 09-16-2016 $1,862,250
Total CVAG Funding Authorization to date: $3,369,000
The Dune Palms Road widening between Blackhawk Way and the new bridge
approach is complete. The CVAG funding provided as part of Amendment 1 has
been expended and reimbursed by CVAG.
The new bridge project is partially funded with Surface Transportation Program
(STP) funds through the State’s Highway Bridge Program (HBP). The HBP will now
provide 88.53%, up to $17,652,222, toward “participating costs” associated with
the proposed all weather bridge spanning the Whitewater River on Dune Palms Road.
The following represents the estimated project budget and proposed funding shares
for the new bridge:

*CVAG Funding Share: $5,395,230
CVWD Funding Share: $58,100
Total Cost: $24,189,652
*CVAG’s Funding Share includes 100% of the requested CV Link Project
Components estimated at $2,142,930.00. The detailed cost estimate for the
CV Link Components is attached for your reference. The costs presented were
prepared using the actual bid information CVAG obtained from bidders during its
recent bid advertisement and award of the CV Link.
The increased project costs of the bridge are primarily due to increases in
construction and right-of-way costs, along with the addition of the CVAG requested
CV Link Elements. The original construction cost estimates were prepared in
conjunction with the original HBP Funding Application in 2011. The original right-
of-way cost did not anticipate the need for eminent domain proceedings due to an
uncooperative property owner on the northeast corner. The original cost estimate
did not anticipate the enhanced CV Link project elements requested by CVAG.
The City of La Quinta is finalizing the right-of-way phase and anticipates having a
shovel ready project by March 2021. Construction is expected to begin as early as
June or July 2021.
