Council Meeting: May 11, 2004 Santa Monica, California
To: Mayor and City Council
From: City Staff
Subject: Award of Professional Services Agreement for the Design of the Centinela
Basin Urban Runoff Mitigation Project
Introduction
The report recommends that the City Council authorize the City Manager to negotiate
and execute a professional services agreement with Black & Veatch Corporation in an
amount not to exceed $250,000 to provide design services for the City?s Centinela Basin
Urban Runoff Mitigation Project. This project is funded through grants from the California
Integrated Waste Management Board ($750,000), Proposition 12 ($500,000), and
Proposition 13, Phase III ($600,000).
Background
Council adopted the City of Santa Monica?s Sustainable City Program in September
1994 with the resolve that City actions that affect the natural environment must not
jeopardize the prospects of future generations. This program was developed to create
the basis for a more sustainable way of life both locally and globally through the
safeguarding and enhancement of its resources and by preventing harm to the health of
the natural environment.

In compliance with the Sustainable City Plan, staff applied for and received grants to
implement an urban runoff pollution mitigation system for the Centinela Basin Watershed
to reduce urban runoff pollution, including dry weather flows, entering nearby Ballona
Creek, the receiving water body for the City?s eastern border. The Creek also enters
directly the Santa Monica Bay. Both water bodies have degraded water quality which
reduces a variety of beneficial uses, such as swimming and fishing. These water bodies
are listed on a national list of impaired water bodies, which requires urban runoff
remediation. Therefore, the City is taking proactive steps to improve water quality and
restore beneficial uses to our local waters.
The project water quality criteria objectives include;
A maximum total suspended solids (TSS) in the treated storm water of 75 mg/liter,
?
Removal of 80% of soluble pollutants including oil and grease,
?
th
Removal of 100% of solid materials larger than 1/8 inch diameter, and
?
Treat up to ¾ inch of storm water for the tributary area over 24 hours (i.e. storm
?
event).
Black & Veatch prepared a feasibility study for the installation of a pollution mitigation
device to address these objectives on the existing Centinela Avenue storm drain system
and examined alternative sites which would best meet the projects objectives.
Black & Veatch concluded that two potential sites for the project exist; one along Virginia
Avenue north of the Santa Monica Freeway (City of Santa Monica) and one in Mar Vista
Park (City of Los Angeles). City staff evaluated the benefits and drawbacks for siting the
2
treatment system in each location and concluded that the Mar Vista site offered the most
benefits such as open spaces for construction; easy access for operation and
maintenance; few if any utilities conflicts; adequate level of runoff flow for year-round
treatment to satisfy grant requirements; pipe capacity for storm flow events without
flooding dangers; and close proximity to the open Sepulveda Channel for flood relief.
Staff met with representatives from the City of Los Angeles Watershed Protection
Division and County of Los Angeles Watershed Management Divisions to discuss this
project and both are very supportive. This is a unique opportunity for inter-agency
cooperation on a project that benefits the entire region. Staff will return to Council to
request authorization for the City Manager to execute an agreement with the City of Los
Angeles for this project. The agreement would allow City of Santa Monica staff access to
the treatment system for periodic maintenance.
Discussion
With the project feasibility now establishedstaff recommends proceeding with the award
of the design contract for the Centinela Basin Urban Runoff Mitigation Project.
Preliminary design work is needed now in order to submit documents to the City of Los
Angeles in support of the Mar Vista Park site. Black & Veatch will not be authorized to
proceed beyond the preliminary design stage until the City of Los Angeles enters into an
agreement with Santa Monica for use of the park site for this project.
On August 18, 2003 a Request for Proposal (RFP) was issued for Design Services of the
3
Centinela Avenue Urban Runoff Mitigation Project. On October 6, 2003 four proposals
were received. A selection committee was formed from staff of the Environmental and
Public Works Management Department. The selection committee reviewed the
proposals submitted by Boyle Engineering, Black & Veatch Corporation, Burns &
McDonnell and AKM Consulting Engineers. The selection criteria included the firms?
technical competence; staffing capability to meet project timeliness; design strength of
the project team; approach to the work; quality control; cost of services and innovative
design alternatives. Three of the firms, Boyle Engineering, Black & Veatch and Burns &
McDonnell, were short listed to make a presentation on October 28, 2003. Based on all
of the relevant rating factors, the selection committee recommends Black & Veatch for
Design of the Centinela Basin Urban Runoff Mitigation Project.
Budget/Financial Impact
Funds are available for this project in the amount of $250,000 in account
C200797.589000 ?Pollution Prevention Grant?.
Recommendation
Staff recommends that the City Council:
1. Authorize the City Manager to negotiate and execute a professional services
agreement with Black & Veatch Corporation for design services in an amount not
to exceed $250,000; and
2. Authorize the City Engineer to issue any necessary change orders to complete
additional work within budget authority.
