Council Meeting: January 10, 2006 Santa Monica, California
TO: Mayor and City Council
FROM: City Staff
SUBJECT: Authorize the City Manager to Negotiate and Execute Two Grant
Agreements with the State of California; to Adopt Resolutions to
Receive Grants to Support the Bicknell Green Street Urban Runoff
th
Project and the 16 Street Multi-Stage Urban Runoff Treatment-
Reuse Project; and Authorize the Appropriation of Grant Funds
Introduction
This report recommends that the City Council authorize the City Manager to
negotiate and execute two grant agreements with the State Water Resources
Control Board from Proposition 50, Chapter 5 funding for the City?s urban runoff
improvement projects. The proposed projects are comprised of the construction
of sub-surface urban runoff treatment systems along Bicknell Street between
th
Main and Fourth Streets, and in the City?s 16 Street Watershed, adjacent to
Marine Park. The report also requests that Council adopt resolutions to receive
the grant awards and authorize the appropriation of the grant funds.
Background
Federal, state and local regulations require the City to reduce urban runoff
pollution from storm drain discharges into the Santa Monica Bay. Recent
changes in these regulations have shifted the management strategy for urban
runoff control from an end-of-pipe approach to a sustainable watershed
approach, where the entire watershed or storm drainage area is evaluated for
1
stormwater management opportunities. The watershed approach is considered a
best management practice (BMP) and promotes reduction of runoff volume and
prevention of urban runoff pollution as guiding principles.
Discussion
The two proposed projects and their respective grant awards are presented
below. Both projects are intended to help restore water quality and maintain the
beneficial uses of the Santa Monica Bay. In addition, the projects will assist the
City in complying with regulatory requirements imposed by the National Pollution
Discharge Elimination System and Total Maximum Daily Loads mandates. A
prior staff report dated June 22, 2004 provides additional information regarding
th
the 16 Street project.
Bicknell Green Street Urban Runoff BMP Project
The construction of the Bicknell Green Street Project, with an estimated total cost
of $724,494, is being funded in part by the State?s Proposition 50, Chapter 5
grant program. The grant award of $450,000 is expected to cover a major
portion of the construction costs. The proposed treatment system includes the
installation of permeable surfaces in gutters and parking lanes to allow urban
runoff to infiltrate through the pavement into the ground, thereby removing a
variety of soluble pollutants and preventing them from reaching the Bay.
If successful, it is anticipated that this demonstration project will encourage other
2
municipalities to adopt this strategy in streets and other paved areas throughout
California. A similar green street was successfully built in Seattle.
th
16 Street Multi-Stage Urban Runoff BMP Project
th
The construction of the 16 Street BMP treatment system, with a cost estimated
to be $1,765,186, is also being funded in part by the State?s Proposition 50,
Chapter 5 grant program. The grant award of $500,000 is expected to cover a
portion of the construction costs. This treatment system is proposed to be
located adjacent to Marine Park and includes a primary separation-screening
chamber to remove trash, debris, sand, oil and grease, as well as other soluble
pollutants, and a secondary filtering system to further treat the runoff. From this
treatment system, treated water will flow into a cistern-leach field where the
treated water will be stored for reuse or will percolate into the ground. Treated
water exceeding the capacity of the percolation system will flow back into the
storm drain system and into the Bay.
The City has also been awarded a Federal 319 grant of $470,000 to help fund
this project.
Budget/Financial Impact
The following budget changes are needed to record receipt of the grant awards
and make them available for program use:
1. Establish a revenue budget in the amount of $450,000 at account
3
number 20662.403680.
2. Appropriate $450,000 in capital improvement project number
C200701.589000 (Prop 50 ? Bicknell Green Street Runoff BMP).
3. Establish a revenue budget in the amount of $500,000 at account
number 20662.403690.
4. Appropriate $500,000 in capital improvement project number
th
C200703.589000 (Prop 50 ? 16 Street Runoff BMP).
Staff is currently identifying potential funding sources for the balance of the
project budgets and, once the necessary additional funding is secured, will return
to Council in the latter part of 2006 for final projects? approval.
Recommendation
Staff recommends that the City Council authorize the City Manager to negotiate
and execute two grant agreements with the State Water Resources Control
Board, adopt the attached resolutions in support of the installation of urban runoff
th
treatment systems in the City?s 16 Street Drainage Basin adjacent to Marine
Park and along a portion of Bicknell Street, and appropriate grant funds as
identified in the above budget changes.
