Dune Palms Low -Water Crossing (Replace):
City Project 2011-05; Federal Aid Proj. # BRLKS-5433(014)
Additional Work Request #4
29 April, 2016
Background
The existing low-water crossing at Dune Palms Road was constructed when the CVWD channel was
constructed through the area, affecting the existing County roadway system.
The Dune Palms low-water crossing was built as part of the transportation network —as "a road" --in
accordance with the understanding, budget, and engineering practice at the time.
As funding became available, the low-water crossings at Adams and Jefferson were replaced with
bridges, leaving Dune Palms Road as the final low-water crossing within this reach. Like the bridges at
Adams and Jefferson Streets, removing and replacing the Dune Palms Low -Water Crossing with an all-
weather bridge is the core of the federally -funding bridge project.
As a consequence from the removal of the existing Dune Palms Road Low -Water Crossing to build the
proposed bridge, the channel grades will likely adjust through the reach. This is because through no
likely intention, the existing Dune Palms Road Low -Water Crossing is also serving as a non -engineered
channel grade control structure.
In order to avoid changes in channel grade resulting from the removal of the existing low-water crossing,
the City requested that Bengal develop concepts to consider replacing the existing low-water crossing
with an "engineered" grade control structure. This proposal addresses the requested task.

Additional Work Request #4
29 April, 2016
Additional Scone of Services, "Exhibit A":
Task 1 Develop Three Concept Alternative Grade Control Structures at Dune Palms Road
At the City's request, Bengal evaluated three options for grade control structures to replace the low-
water crossing at Dune Palms Road.
Scope of work:
• Concept Design Analysis: 3 Alternative Grade Control Structures
• Concept Plans: 3 Alternative Grade Control Structures
• Cost Estimates: 3 Alternative Grade Control Structures
While Bengal found that any three alternatives had the potential to stabilize the channel in accordance
with CVWD's desires, implementing a grade control structure within the scope of the bridge project was
infeasible because of complexity and cost.
As a result of this study it became clear that changes to the CVWD channel are a larger regional issue to
be address outside of the scope of the Dune Palms Road Bridge Project.

STAFF REPORT
AGENDA TITLE: APPROVE AMENDMENTS 4 AND 5 TO BENGAL ENGINEERING, INC.'S
PROFESSIONAL SERVICES AGREEMENT ASSOCIATED WITH THE DUNE PALMS ROAD
BRIDGE IMPROVEMENT
RECOMMENDATION
Approve Amendments 4 and 5 to Bengal Engineering, Inc.'s Professional Services
Agreement associated with the Dune Palms Road Bridge Improvement.
EXECUTIVE SUMMARY
• The City's professional services agreement (PSA) requires compensation for
additional services that exceed five percent of the total contract amount be
approved by the City Council.
• The addition of Amendments 4 and 5 (Attachments 1 and 2) exceed the five
percent limit for a total increase (Amendments 1 through 5) of $73,245 or 6.2
percent above the original contract sum.
• Amendment No. 4 ($16,100) authorizes the design consultant to develop three
grade control structure alternatives. Amendment No. 5 ($19,900) authorizes
them to provide additional hydraulic information on the Coachella Valley
Stormwater Channel. Both items are needed to respond to comments received
by Coachella Valley Water District (CVWD) on the Bridge Hydrology Report.
FISCAL IMPACT
The original design contract was $1,176,781. Amendments 1 through 5 increase the
contract amount by $73,245 for a new all -in contract cost of $1,250,026. Adequate
funding is available for the requested amendments. The following is the approved
project budget:
Professional:
$250,000
Design:
$1,500,000
Inspection/Testing/Survey:
$1,630,000
Construction:
$12,000,000
Right of Way Acquisition:
$545,000
Contingency:
$1,585,000
Total Budget:
$17,510,000
The Dune Palms Road Bridge Project has an approved budget of $17,510,000. The
project is partially funded with Federal Surface Transportation Funds through the
State's Highway Bridge Program. Federal funds will provide 88.53 percent (up to
$15,501,603) of the total project costs. The Coachella Valley Association of
Governments will fund 75 percent of the remaining 11.47 percent local share (up to
$1,506,750). The City is responsible for the remaining 25 percent of the local share in
the amount of $502,250.
BACKGROUND/ANALYSIS
In June 2014, the City Council approved a design contract with Bengal Engineering to
provide professional engineering services to design an all weather bridge and replace
the Dune Palms Road low water crossing at the Whitewater Channel (Attachment 3).
The project is currently in the environmental and permitting phase. Bengal Engineering
prepared a hydrology study describing the impacts to the Coachella Valley Stormwater
Channel when the low water crossing is replaced with an all weather bridge. CVWD
reviewed the hydrology study and submitted comments. Contract Amendments 4 and
5 allow Bengal Engineering to perform the work necessary to address CVWD's
comments.
ALTERNATIVES
Since a CVWD encroachment permit will be required and the proposed bridge spans
CVWD's right of way, no alternative is recommended.
