CITY COUNCIL STAFF REPORT
Agenda Item No. 7
October 11, 2005
TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: Public Works Department
Robert Stein, P.E.

rstein@city.newport-beach.ca.us
SUBJECT: NEWPORT BOULEVARD BIOSWALE - AWARD OF CONTRACT
NO. 3741
RECOMMENDATIONS:
1. Approve the drawings and specifications.
2. Award Contract No. 3741 to Belaire -West Landscape for the Total Bid Price of
$196,252 and authorize the Mayor and the City Clerk to execute the contract.
3. Establish an amount of $19,000 to cover the cost of unforeseen work.
4. Establish an amount of X2,000 to cover the geotechnical testing.
5. Approve a Budget Amendment transferring appropriations of $14,251.78 from
General Fund 7014- C5100805 (Morning Canyon Stabilization Project) into Account
No. 7014- C5100596.
DISCUSSION:
The City's 2004 Storm Water Diversion Study sampled the dry weather flow in the V-
Ditch running along the east side of Newport Boulevard South of 15th Street and found
high loadings of fecal indicator bacteria. This flow comes from a 500 -acre drainage
area predominately within the City of Costa Mesa though there are contributing areas
from Caltrans and the City of Newport Beach. Computer modeling strongly indicates
that these bacteria are tidally pumped into the Newport Island Channels once this flow
outlets into the Bay at the Turning Basin near the Arches Bridge. This proposed
bioswale will create an infiltration basin to infiltrate some of the 30,000 gallons per day
flowing through the V- ditch. The site is owned by the State of California and will be
maintained by City forces as part of the encroachment permit conditions.

At 11:00 a.m. on September 27, 2005 the City Clerk opened and read the following bids
for this project:
BIDDER TOTAL BID AMOUNT
Low Beiaire -West Landscape $196,252.00
2 Mega -West Enterprises $197,154.16
3 GCI Construction $298,222.20
The low total bid amount is twelve percent above the Engineer's Estimate of $175,000.
The low bidder, Belaire -West Landscape, possesses a California State Contractors
License Classification A and C27; either license would satisfy the requirements of the
project specifications. A check of the Contractors references indicates they have
satisfactorily completed similar projects for other municipalities.
Project work includes clearing the iceplant in the swale along East side of Newport
Boulevard South of 16th Street, installing rock, sand and gravel to create an infiltration
bed, re- landscaping the swale with native type trees and plants, and hydroseeding the
area.
Per the Contract Specifications the Contractor will have 45 consecutive working days to
complete the work.
Environmental Review:
This project qualifies for a Categorical Exemption pursuant to Section 15302
(Replacement or Reconstruction) of the Implementing Guidelines of the California
Environmental Quality Act. This exemption permits minor alterations to exiting public
and private structures that involve negligible expansion of use. Existing drainage
patterns, hydraulic flow and flood control will not be impacted. The site has no sensitive
vegetation.
Public Notice:
Not Applicable. The site is not close to residences or businesses.
Geotechnical /Survey Services:
The City will retain a geotechnical engineer to perform appropriate compaction tests on
regraded slopes and fill areas.

Funding Availability:

in the following accounts for the project. There is a $203,000.22 unencumbered
balance on this project currently available in the Contributions Fund. The remaining
$14,251.78 would become appropriated as a Budget Amendment if Recommendation
No. 5 of this Council Memo is approved.
