Recommendation:
By minute motion, approve:
1. Amendment No. 4 to Contract No. C22870 with Moffatt & Nichol in the
amount of $59,500.00 to design the widening of southbound Portola
Avenue between the Portola Bridge and Magnesia Falls Drive
(adjacent to Palm Desert Mobile Estates), and
2. The appropriation of $59,500.00 for this amendment from unobligated
funds in Account 400.
Background:
On October 4, 2004, City Council approved Contract No. C22870 with Moffatt & Nichol for
design and construction support services in the amount of $563,467.00, plus a 10%
contingency for the Portola Bridge over the Whitewater Channel Project. On July 14, 2005,
City Council approved Amendment 1 to Contract No. C22870 in the amount of $50,751.00
for additional services to address unforeseen design requirements. City Council on August
24, 2006, also approved Amendment 2 to Contract No. C22870 in the amount of
$48,500.00 for additional construction design support services to address unforeseen
requests for information, previous change orders, and the girder failure that occurred.
On July 31, 2006, the east half was completed and traffic was moved to that portion of the
bridge. Construction of the entire bridge is scheduled to be complete in June 2007.
Discussion:
In order to expedite the bidding and completion of the Portola Bridge, no sidewalk was
provided along the west side of Portola Avenue between the new bridge and Magnesia
Falls Drive (adjacent to Palm Desert Mobile Estates). To widen the street and provide the
sidewalk would require the acquisition of approximately 12 feet of right-of-way, which would
have delayed the project.
Amendment 4 to C22870 with Moffatt & Nichol-Portola Bridge over Whitewater
Page 2 of 2
February 22, 2007
The gap in the sidewalk is undesirable and will require southbound pedestrians on Portola
Avenue to cross at Quicksilver Drive. Staff recommends the design of the street widening
proceed at this time, in order to provide the sidewalk and accommodate the future widening
of southbound Portola Avenue as a separate project. Staff also recommends that Moffatt &
Nichol design these improvements because they have much of the engineering data for this
area and would thus be able to expedite the widening at a lower design cost.
The design services include the following:
• Soundwall acoustic study
• Field survey
• Utility coordination
• Preparation of right-of-way legal descriptions and plots
• Geotechnical review
• Preparation of plans, specifications, and estimates for street widening and design of
retaining/soundwail
The estimated construction cost of the street widening is approximately $600,000.00. The
widening will require the acquisition of the 12-foot right of way and one mobile home and
some parking lot modifications. The total acquisition of right of way is estimated to cost
approximately $700,000.00. The construction and right of way acquisition costs will need to
be budgeted next fiscal year.
Staff has determined that the negotiated costs for the additional design services are
equitable and recommends that City Council approve Amendment 4 to Contract C22870
with Moffatt & Nichol in the amount of $59,500.00 and authorize the Mayor to execute the
amendment. The revised total contract amount of $755,133.00 is approximately 7.5°l0 of
the construction cost, which is well within the acceptable range.
This unforeseen expenditure was not budgeted. Therefore, staff also requests approval- o
the appropriation of $59,500.00 from unobligated funds in Account 400 for this expendVjr

Subj: Portola Avenue Bridge over the Whitewater River Channel
M&N File: 55321CPD-31L
Dear John:
Below is our proposal to develop PS&E to widen the west side of Portola Avenue from
Magnesia Falls Drive to the end of the new bridge just south of tlie Whitewater River as shown
on the accompanying sketch. We understand that this project will be advertised as a "stand-
alone" project. After widening, the westerly ctub of Portola Avenue wi11 be 44 ft. from the
existing centerline and an 8 ft wide sidewalk will be provided behi_nd the curb. As you are
aware, this will i-equire the acc�uisition of about 8 ft. of right-of-way from the adjacent mobile
home park(perhaps slightly more to accommodate retainulg wall). The construction will need to _
include:
■ Pavement widening
■ New curb, gutter and walk
■ Approximately 400 ft. long retaining wall ranging from 2 ft to aUout 7ft. height
■ New soundwall/screen wall at moUile home parlc
■ Grading,p�ving and short retainirig walls at mobile home park entrance
■ Modification of existing traffic signals and control panel at Magnesia Falls/Portola
intersection
■ Relocation of water distribution valve box ancl BFP's
■ Relocation of fire hydrant
■ Adjustment(reconstruction) of SCE manllole
■ Adjustment to existing catch basin
■ Minor regrading at Channel Access Road
We propose the following budget for our design services:
1. Soundwall Acoustic Study......................................$ 4,000
2. Field Survey............................................................$ 3,000
3. Utility Coordination................................................$ 4,000
4. CVWD Coordination..............................................$ 1,500
5. Preparation of R/W legal d�scription and plot........$ 1,500
6. Preparation of Construction Plans ..........................$37,500
7. Preparation of Specification Booklet......................$ 4,000
(Technical Sections only)

9. Geotechnical Foundation Review...........................$ 2,000
