Recommendation to Accept Proposition A Grant Funding and Award Two
Sole Source Contracts to Install Catch Basin Filtration Devices and Retrofit
the PIer Storm Drain
IntroductIon
ThiS report recommends that the City Council accept $271,500 in Proposition A grant
funding. award a construction contract to CDS Technologies, Inc In an amount not to
exceed $236.750 to retrofIt the Pier storm dram, and Issue a purchase order to the
Regents of the Umverslty of CalifornIa (at Los Angeles), CIVil and Environmental
Englneenng Department, In an amount not to exceed $34,750 to Install and mOnitor catch
basin filtration devices
Background
In November 1996. voters approved Los Angeles County PrOpositIon A, the Safe
Neighborhood and Parks Act The Act allocated grant funds for capital projects to be
awarded for the purpose of restonng and Improvmg the Santa MOnica Bay by reducmg the
tOXICIty and/or pollutant load In runoff to the Santa MOnica Bay Grant money IS avaIlable
for capital projects which will directly lead to a measurable reduction of runoff pollutants

On July 22. 1997. the City Council adopted a resolution approving the City's appllcatron
for funds to retrofit storm drains and Install catch basin devices to filter out stormwater
runoff contaminants Catch basins are the curbsIde Inlet connections to stormdrams The
speCific retrofit device IdentifIed In the proposal was the Continuous Deflective Separator
(CDS) umt
On December 12, 1997, the County notified the City that Its proposed projects were
selected for fundmg by the Executive Officer of the Los Angeles RegIonal Water Quality
Control Board (RWQCB) The City will receive the grant funds m reimbursement
payments from Los Angeles County
DISCUSSion
The two methods the City proposed for controlling and reducing Indirect sources of
polluted runoff will reqUire separate contractual arrangements The pnmary difference
between the two systems IS that one IS a large, patented, self-contained Unit Installed
beneath the street and attached to a storm drain to remove sediment, trash and debrrs
from Its flow ThiS unit IS available from CDS Technologies, Inc The second system IS a
street-level catch basm Insert deVice reqUlrrng no construction or modification of the catch
baSin The CDS Unit, through ItS non blocking screenmg process, IS expected to capture
Virtually 100% of all floatable matenal and over 90% of all matenal that IS larger than 06
Inch In dimenSion The ten foot In diameter Unit Will be constructed below grade at the end
of Moss Avenue, near the beach Promenade, and connected to the Pier storm dram
2
DUring storm flows, the CDS Unit will substantially reduce vIsIble debris from entering the
storm drain and being deposited In the Bay A secondary benefit will be to the planned
dry weather runoff reclamation faCIlity at Moss Avenue and Appian Way The CDS Unit will
capture a substantial portion of the larger debris from the Pier storm dram before a
wastewater diverSion line carnes It to the plant for treatment The City and CDS staff will
mOnitor and assess thiS Unit for Its effectiveness In removing sediment and debris from
gross flow volume
The second method for reducing the pollutant load In urban runoff IS to attach filtration
devices to the catch basins A recent research project sponsored by the Santa MOnica
Bay Restoration Project and a consortium of 15 local Cities and agencies, spearheaded by
the City of Santa Monica. evaluated the effectiveness of commercially available devices
The study indicated that most commercially-available devices were not sUitable for two
reasons First. they would reqUIre costly constructIon to reconfrgure our standard catch
basin size and, second, they might Impair the hydraulic flow of runoff water, possibly
causing flooding The UCLA researchers and the consultants to the project from
Woodward-Clyde developed prototype catch basin Insert devices which inexpensively
combine filter, baffle wall, and screen elements for the most cost-effective Insert UCLA
Will construct SIX prototypes for installation In catch basins owned by the CIty of Santa
MOnica The prototypes are generally described as a basket hung In the catch basin by
chams to trap debriS and large SOlids, an absorber to remove 011 and grease, and a baffle
to create a sedimentation chamber to trap fine particles such as sand and soot
3
It IS expected that the Inserts will remove 70 to 90% of these pollutants The deVices will
be Installed by UCLA with the assistance of City personnel
SIX Santa MOnica locations will be used In the first field test of the catch baSin Inserts The
three land-use areas which Will be used are commercial With heavy pedestnan traffic,
commercial WIth runoff from vehicle parkmg. and reSidential With single and multiple family
dwellings Two deVices Will be used for each land use The relative efficiency of each
deVice Will be assessed and future maintenance requirements Will be determined by UCLA
and City staff
The Water/Wastewater DIvISion staff have been Involved In setting the deSign parameters
of the prototype catch baSins and In selecting the locations In the City of Santa MOnica
They Will also be Involved In installing, maintaining, and removing captured debns samples
for analYSIS by UCLA The deVices, once Installed, Will be the property of the City
Englneenng DIvIsion staff Will also provide project management services to fulfill the
matching fund requirements of the agreement Both projects are expected to be
completed by June 30, 1999
Section 224080 of the Santa MOnica City Code prOVides exceptions to the competitive
bidding process and allows the award of construction contracts to the sole manufacturers
of a product CDS Technologies, Inc, IS the sole manufacturer of CDS units, and UCLA
4
IS the developer of the prototype catch basin filtratIon devices Identified In the grant
proposal Furthermore, the 15 Cities In the catch basin study consortium fully support
UCLA's field testing of their prototype catch basm devices ThiS continues the research
the consortium previously funded It IS anticipated that the findings from thiS testing will
provide cities with a viable and cost-effective means of reducmg urban runoff pollution
Budget/Financial Impact
The grant application requested and the City was awarded $271,500 The cost for the
purchase. InstallatIon, and mOnitoring of the CDS unit IS 5236,750 The SIX catch basin
devices will cost $34.750 for construction, installation, construction management, and
mOnltonng The City IS required to proVide a 15% match for the entire project equaling
$40,725 The match requirements will be met through In-kind services such as monltonng.
project management, Insert device installation, and maintenance Annual operations and
mamtenance funds are avaIlable m account 31-500-661-00000-6663-00000
Upon Council approval of staff recommendations, a new revenue budget Will be
established and revenue account 20-500-402-00000-0611-10000 , "Catch Basin Study 2,"
to receive reimbursement funds totaling $271,500, and CIP account 20-720-402-20098-
8900-99625 Will be established for project expenditures totaling $271,500

Recommendation
Staff recommends that the City Council
1 Waive competitive bidding requirements for both CDS Technologies, Inc, and the
Regents of the Umverslty of California,
2 Award a construction contract to CDS Technologies Inc , In the amount of $236,750
and Issue a purchase order to the Regents of the University of California, CIVil and
Environmental Englneermg Department, in an amount not to exceed $34,750, and
3 Approve the new revenue budget and account 20-500-402-00000-0611-10000 for
$271,500, and approve CIP account 20-720-402-20098-8900-99625 In the amount
