Recommendation:
By minute motion, approve and authorize the Mayor to execute
Amendment No. 2 to Contract C22310A with RBF Consulting, Inc. in the
amount of $67,948.00 for landscaping and aesthetic design services for
the Monterey Avenue Interchange Ramp Improvement Project on
Interstate 10.
Discussion:
On October 14, 2004, City Council approved Contract C22310A with RBF Consulting,
Inc. in the amount of $237,055.00 for engineering services to prepare the plans,
specifications and estimate (PS&E) for the proposed westbound on- and off -ramp
modifications at the Monterey Interchange on Interstate 10 (1-10). The ramp
modifications consist of realigning the westbound 1-10 off -ramp to Varner Road and
inserting a loop on -ramp from northbound Monterey Avenue to westbound 1-10. This
will eliminate the congestion and queuing experienced on northbound Monterey Avenue
for vehicles entering the westbound 1-10 on -ramp. Design of the improvements is
scheduled to be completed late this year and award of the construction contract in
Spring 2008.
On July 13, 2006, City Council approved Amendment No. 1 to Contract C22310A with
RBF Consulting in the amount of $157,710.00 for additional engineering services to
complete the PS&E including the design of an unforeseen retaining wall, soundwall, and
a future lane through the interchange.

Because of the impending modification of the ramps, the landscaping in the areas that
would be affected by construction were deleted from the recently completed County of
Riverside landscaping project. The landscaping design and installation will now be
included with the ramp improvement project PS&E. We currently have a federal
Transportation Enhancement Grant in the amount $378,000.00 (City match of
$422,000.00) to fund the installation of landscaping.
Staff has prepared Amendment 2 to Contract C22310A resulting from negotiations with
RBF for the landscaping and aesthetic design services not included in the original scope
of work. Staff has determined that the negotiated cost is equitable for the additional
services rendered. Staff therefore recommends that City Council, by minute motion,
approve Amendment 2 to Contract C22310A with RBF, Inc. in the amount of
$67,948.00. Funds for this amendment are available in Project Account No. 213-4389-
433-4001.
