Subject: Design Agreement for the Bicknell Avenue Street Greening Project
Recommended Action
Staff recommends that the City Council:
1. authorize the City Manager to negotiate and execute a modification to the
professional services agreement with Kimley-Horn and Associates, Inc. in an
amount not to exceed $106,000 for design services of the Bicknell Avenue Street
Greening Project; and
2. appropriate $106,000 from the Stormwater fund balance for the professional
services agreement with Kimley-Horn and Associates.
Executive Summary & Discussion
On March 11, Council reviewed concept design options and provided input on the
Bicknell Avenue Street greening project between Neilson Way and Main Street. A
component of the staff report recommended that $106,000 be appropriated from the
Stormwater Fund balance in order to increase the professional services agreement with
Kimley-Horn Associates in order to develop schematic design documents for the project
based on input received by Council on March 11, 2008. At the time the matter was
heard there were four Council members p resent. Since the appropriation of funds
requires five votes, the appropriation of funds and the related modification to the
professional services agreement was continued to the March 25, 2008 Council meeting.

Subject: Concept Design, Modification of Professional Services Agreement with
Kimley-Horn and Associates, Inc. and Appropriation of Funds for the
Bicknell Avenue "Green Street" Project
Recommended Action
Staff recommends that the City Council:
review the concept design options and provide input on the development of a
preferred concept design option;
2. authorize the City Manager to negotiate and execute a modification to the
professional services agreement with Kimley-Horn and Associates, Inc. in an

Street Greening Project; and
3. appropriate $106,000 from the Stormwater fund balance for the professional
services agreement with Kimley-Horn and Associates.
Executive Summary
The Bicknell Avenue "Green Street" Project is a mostly grant-funded demonstration
project intended to provide water quality improvements by reducing the impervious
street surface and installing landscaped infiltration strips to reduce the quantity and
improve the quality of storm water runoff. The location of the project is a one block area
on Bicknell Avenue between Ocean Avenue and Neilson Way. Several options for
implementing the proposed improvements were developed to address the water quality
improvement aspects of the projects as well as other necessary uses of the street right-
of-way including parking, traffic, operations and access for emergency services. The
improvement options were discussed with the community at a public meeting held in
November 2007. Staff seeks input from City Council on the attached design options
prior to returning to the community to finalize the concept design.
Kimley-Horn and Associates, Inc. is recommended for design services associated with
the implementation of this project and has developed the preliminary concepts. The
modification to the professional services agreement will not exceed $106,000.
Following appropriation, the agreement will be funded from the Stormwatet fund
balance.
Discussion
Federal, state and local regulations require the City to reduce urban runoff pollution
from storm drain discharges into the Santa Monica Bay. The Bicknell Avenue "Green
Street" project is intended to improve water quality and maintain the beneficial uses of
the Santa Monica Bay, as well as improve the street's aesthetics. This project will
assist the City in complying with regulatory requirements imposed by the National
Pollution Discharge Elimination System (NPDES) and Total Maximum Daily Loads
(TMDL)mandates.
Bicknell Avenue between Ocean Avenue and Neilson Way is an ideal location for the
proposed "Green Street" demonstration project. The existing street is wide enough (56'
curb to curb) so that reducing the width of the street to install pervious surfaces and
infiltration strips is possible without affecting traffic/pedestrian flow. Additionally, several
blocks of the surrounding area drain to this location and stormwater runoff is collected
into a subsurface storm drain system at the west end of the street near Ocean Avenue.
Therefore, by constructing the improvements at this location, stormwater runoff is
collected and water quality is improved from a larger area of the City beyond the one
block of Bicknell Avenue. The proposed "Green Street" project includes the reduction of
impervious street surface by implementing landscaped infiltration strips adjacent to the
existing curbs and gutters. The landscaped infiltration strips will collect runoff as it flows
along the gutter. Collected runoff will be stored in chambers below the landscaped
strips and will slowly infiltrate into the soil thus reducing the quantity and improving the
quality of stormwater runoff discharged into Santa Monica Bay, and promoting more
sustainable streetscapes. Should this project prove successful, additional streets with
similar characteristics can be retrofitted during routine street reconstruction, through
future grants and watershed capital improvement projects.
2
In developing options for this project, several constraints were identified. The proposed
project area has twelve existing on-street permit parking spaces that need to be
preserved. Any reduction to the width of the street must consider traffic flow and
emergency vehicle access. Additionally, operations such as street sweeping, trash
collection, utility access and landscape/tree maintenance must be maintained.
A professional services agreement was executed with Kimley-Horn and Associates, Inc.
in August 2007 to conduct one community meeting and develop preliminary design
concepts. Three preliminary design concepts were developed by Kimley-Horn and
Associates, Inc. to implement the proposed "Green Street" improvements. In all three
options, the improvements are proposed to be installed in the existing street. City staff
has determined that all three options can be designed to accommodate existing traffic
flows as well as the needs of municipal operations. Therefore, the existing parkway
utilities will not require relocation and the overall cost of implementing the project is
reduced.
Option 1: Install 6 foot wide landscaped infiltration strips adjacent to both the north and
south curbs. This option provides the largest amount of landscaped infiltration strips,
minimizes impervious area and maximizes the amount of runoff that can be infiltrated.
The existing parking is relocated to the new curb face and the amount of on-street
parking remains the same. The street is narrowed by approximately 12 feet but
sufficient width is maintained for parking and emergency vehicle access. The estimated
cost for this option is approximately $700,000.
Option 2: Install 3 foot wide landscaped infiltration strips adjacent to both the north and
south curbs and install two 8 foot wide landscaped median islands in the center of the
street. This option provides a sufficient amount of landscaped infiltration strips and
minimizes impervious area. The existing parking is relocated to the new curb face and
the amount of on-street parking remains the same. Additionally, the median islands
provide aesthetic benefits and separation between traffic lanes although medians limit
3
the amount of continuous right of way available for emergency vehicle access at the
location of the two islands. The estimated cost for this option is approximately $770,000
to $840,000
Option 3: Install 4 foot wide landscaped infiltration strips on the north curb only and
provide perpendicular parking along the south curb. This option slightly reduces the
amount of impervious paving and provides a marginal amount of landscaped infiltration
strips along the north curb only. This option provides the least amount of infiltration of
stormwater runoff and does not accomplish all the objectives of the demonstration
project. Perpendicular parking along the south curb provides approximately seven
additional on-street parking spaces. The street is narrowed slightly due to the infiltration
strip on the north curb and perpendicular parking on the south curb but sufficient
continuous width is maintained for emergency vehicle access. The estimated cost for
this option is $490,000 to $560,000.
The City of Santa Monica has been awarded a $450,000 Proposition 50 grant for design
and construction of an urban runoff treatment demonstration project on Bicknell Avenue
between Neilson Way and Ocean Avenue. On January 10, 2006, City Council adopted
a Resolution authorizing the City to enter into a Grant Agreement with the State of
California and authorizing the City Manager to execute the 2006 Grant Agreement for
the Bicknell Green Street Best Management Practice Demonstration Project. This
project must be substantially completed before the end of 2008 to allow adequate time
to complete water quality monitoring during the 2008-09 rainy season. Results from this
monitoring must be included in the project final report, which will be submitted by March
2009 to comply with the grant agreement funding deadline.
Contractor/Consultant Selection
On February 8, 2007, a Request for Proposal (RFP) with a preliminary scope of
services was posted on the City's website, soliciting proposals to design the Bicknell
Avenue Street Greening Project.
4
On March 19, 2007, three proposals were received from the following firms: KPFF
Consulting Engineers, Kimley-Horn and Associates, Inc. and Psomas. A selection
committee consisting of staff from Civil Engineering & Architecture and Environmental
Programs Divisions reviewed the proposal. On April 18, 2007, the selection committee
interviewed all three consulting firms. The selection criteria included the firm's technical
competence, understanding of the projects scope, direct experience on similar projects,
approach to the work, qualifications of the proposed staff, staffing capabilities to meet
the desired time frames, and cost of services. Based on the proposals and interviews,
the selection committee recommended Kimley-Horn and Associates, Inc. to provide
design services for this project.
After considering the design services cost proposal, it was decided to enter into an initial
contract with Kimley-Horn and Associates, Inc. to develop conceptual design options
and facilitate initial community outreach. On August 9, 2007, a professional services
agreement was executed for $34,000 with Kimley-Horn and Associates, Inc. to develop
a concept design for the Bicknell Green Street Project. It is now proposed that a
modification to the professional services agreement is executed with this firm to finalize
the concept design and develop schematic plans for the recommended option. Upon
approval of the final concept design another modification to the professional services
agreement will be necessary to develop final plans and specifications to construct the
proposed improvements.
Community Outreach
On November 29, 2007, a community meeting was held to discuss the objectives of the
project and solicit input from the community. A mailer was sent to approximately 350
residents adjacent to the project area to notify the community of the upcoming public
meeting. Nine members of the public participated in the meeting. Five of the nine
members of the public were Bicknell Avenue residents that live on the block where the
improvements are proposed and four reside on Bicknell Avenue east of the project area.
5
At the community meeting, residents indicated that although street parking is limited on
this block, there is no desire to add additional parking, as there is sufficient parking
available on Ocean Avenue. A few community members from the area of Bicknell
Avenue near Main Street indicated that parking is extremely limited on Bicknell Avenue
east of Main Street. That area, however, is outside the limits of the project zone. The
community members overwhelmingly supported the concept of constructing the
demonstration project to improve water quality in Santa Monica Bay.
Financial Impacts & Budget Actions
Construction of the project will be primarily funded by the State Water Resources
Control Board through a Proposition 50 grant for $450,000. The total project cost,
including design services and construction, is estimated to be approximately $700,000.
During the design process, staff will confirm funding options for the amount in excess of
the available grant funds. At this time, the source of additional funds is likely to be
Measure V (as adopted by Council on September 25, 2007). Potential increased
maintenance costs associated with these improvements will also be evaluated during
final design.
The following budget action is needed to make funds available for the contract:
appropriate $106,000 from 34 fund balance to account number 0340588.589000
(Stormwater System Improvement). Future appropriations will be required to modify the
professional services agreement to complete final construction documents upon
approval of the final concept design and to execute a construction contract to implement
the improvements.
