Subject: Professional Services Agreement for Monitoring Services for the In -Line
Storm Drain Runoff Infiltration Project
Recommended Action
Staff recommends that the City Council authorize the City Manager to negotiate and
execute a professional services agreement with California Watershed Engineering, a
California -based company, in an amount not to exceed $80,000 (includes a 10%
contingency) to provide flow and water quality monitoring services for the In -Line Storm
Drain Runoff Infiltration Project.
Executive Summary
Santa Monica received $300,000 from Proposition 84 for the In -Line Storm Drain Runoff
Infiltration Project. This pilot project will retrofit existing catch basins and manholes to
capture and infiltrate urban runoff. Under the terms of the grant agreement, the City is
required to perform water quality monitoring upon completion of construction and submit
the data to the State Water Resources Control Board. California Watershed
Engineering is recommended to perform these tasks at a cost not to exceed $80,000.
Background
On November 8, 2011, Council authorized staff to accept a $300,000 grant and
negotiate and execute a grant agreement with the State Water Resources Control
Board to construct the In -Line Storm Drain Runoff Infiltration Project (Project).
The City's agreement with the State Water Board requires water quality monitoring to be
performed upon completion of construction of the Project. The terms of the grant
agreement also requires the monitoring data to be submitted to the State Water Board
at the end of the monitoring period.

Discussion
The In -Line Storm Drain Runoff Infiltration project aims to evaluate the feasibility of
retrofitting existing storm drain infrastructure, such as catch basins and manholes, for
runoff infiltration purposes. After evaluation of the systems, the most effective design
will be considered for use in city -wide installations.
The project is part of the Measure V Five Year Capital Improvement Plan. The project
is anticipated to cost $400,000, and will be co- funded by Proposition 84 and the City's
Clean Beaches and Oceans Parcel Tax. In order to meet the terms of the Proposition
84 grant agreement, the City must monitor water quality upon completion of the project
and submit water quality data to the State Water Board. Water quality monitoring
involves obtaining storm water samples at the project site and performing laboratory
analysis in accordance with the approved monitoring plan. Construction of the project is
anticipated to be completed by September 2013. The City's draft monitoring plan
proposes to monitor the project from October 2013 to April 2014.
Consultant Selection
On November 1, 2012, a Request for Proposals (RFP) was posted on the City's online
bidding site for services to perform flow and water quality monitoring for the In -Line
Storm Drain Runoff Infiltration Project. Fifty -two firms obtained copies of the RFP. On
December 10, 2012, four proposals were received from the following firms:
Firm Cost Proposal
California Watershed Engineering $71,697
AEI -CASC Consulting $153,858
AMEC Environment & Infrastructure, Inc. $178,500
Civil Environmental Survey Group, Inc. $192,302
Staff from Public Works reviewed the proposals. The selection criteria included
competitive pricing, qualifications of the proposed staff, understanding of the project's
scope and direct experience with similar projects.

Based on these criteria, staff recommends California Watershed Engineering (CWE) as
the best bidder to provide monitoring services for this project.
CWE's proposal exhibited a detailed understanding of the project requirements.
Proposals from the other firms were substantially higher than CWE due to their high unit
costs for water quality grab samples. The latter comprises the largest portion of the
scope of work. CWE performed similar services for the Los Angeles World Airports,
County of Orange John Wayne Airports and the City of Santa Monica's Bicknell Avenue
Green Street Project. Staff verified that CWE's contract lab is certified by the California
Department of Health Services. Additionally, staff contacted the listed references and
all references reported being extremely satisfied with the company's expertise on storm
water issues.
Financial Impacts and Budget Actions
The professional services agreement to be awarded to California Watershed
Engineering is for an amount not to exceed $80,000 (includes a 10% contingency).
Funds will be reimbursed as authorized by the State Water Board. Funds are available
in the FY 2012 -13 Capital Improvement Program budget in account C209031.589000.
