BACKGROUND
The State Water Resources Control Board (SWRCB) works in coordination with nine Regional Water Boards to implement the Federal Water Pollution Control Act (Clean Water Act) to preserve, protect, enhance and restore water quality throughout California. Pursuant to the Clean Water Act, the State’s Municipal Storm Water Program regulates storm water discharges from municipal separate storm water systems (MS4s) through the issuance of MS4 Permits.
The Los Angeles Regional Water Quality Control Board Order No. R4-2012- 0175, as amended by State Water Board Order WQ 2015-0075, regulates discharges of storm water and non-storm water from the MS4s operated by the Los Angeles County Flood Control District, Los Angeles County and 84 municipal permittees (including the City of San Marino) in a drainage area that encompasses more than 3,000 square miles and multiple watersheds. The Los Angeles County MS4 Permit requires Permittees to reduce the level of pollutants, including trash, debris and sediment, from entering the area’s water bodies from the storm sewer systems owned or operated by the Permittees.

In 2015, the SWRCB adopted Resolution 2015-0019 (Resolution) amending the Water Quality Control Plan for Ocean Waters of California (California Ocean Plan) to control trash impacts to the surface waters of California. This Resolution finds that trash in California’s surface water is a pervasive problem and adversely affects numerous beneficial uses including, but not limited to, wildlife habitat, marine habitat and human water contact and non-contact recreation. Studies have shown that trash is predominantly generated on land and then transported to surface waters through the storm drain system. This Resolution establishes a statewide narrative water quality objective and implementation requirements to control trash. The SWRCB directed each of the nine Regional Water Quality Control Boards to incorporate trash provision requirements into their MS4 Permit. The City is subject to this mandate which requires the installation of trash capture devices that capture litter and trash down to 5 mm in size, to prevent this debris from reaching receiving waters such as rivers, creeks and the Pacific Ocean.
In 2018, Los Angeles County voters approved Measure W, that created the Safe Clean Water Program (SCWP) and allowed for the collection of a special parcel tax of 2.5 cent ($0.025) per square foot of impermeable area on private property in the LA County Flood Control District. Through Measure W, the SCWP provides local, dedicated funding to increase regional water supply, improve water quality, and enhance communities throughout Los Angeles County with forty percent (40%) of the funding from the SCWP allocated to cities as local return. On average, the City has received approximately $235,000 per year the past four years to address local stormwater and urban runoff challenges and opportunities.
On May 31, 2024, the City Council adopted the Fiscal Year 2024-25 Operating and Capital Improvement Program (CIP) budgets. As part of CIP budget, the City Council approved an appropriation of $100,000 for the procurement and installation of trash and debris capture devices in catch basins utilizing Measure W Safe Clean Water Program funds. The installation of these devices will help prevent trash, debris and other objects from entering the storm drain system and polluting the stormwater, helping ensure compliance with State and Regional Water Board regulations.
DISCUSSION
The procurement and installation of trash and debris capture devices is a continuation of a City program that began in 2020, during which ARS-CLTM curb-opening screens were installed in 72 City-owned catch basins by G2 Construction, Inc. The program continued in FY 23-24 when 30 new devices were installed in City-owned catch basins. This program is part of an ongoing effort to comply with MS4 Permit requirements to keep trash, debris and sediment from entering the storm drain system. There are currently 78 Cityowned catch basins remaining that will need trash and debris capture devices installed. The City has planned to retrofit the catch basins in multiple phases to spread construction costs over multiple years. G2 Construction, Inc. provided a proposal for the fabrication and installation of thirty-nine (39) new full capture systems in City-owned catch basins. Additionally, G2 will also fabricate and install curb-opening devices in seven (7) catch basins that currently do not have a curb screen. The total cost for this work is $100,000.
Trash and debris capture devices are unique products that must be customized and fabricated for each catch basin in order for the device to function properly.
G2’s proprietary ARS-CLTM curb-opening screens and CPS-ModTM Full Capture Screens are unique patented storm water treatment devices made from 304 stainless steel that are designed and custom fabricated by G2 to the specific dimensions of each specific catch basin or inlet. This enables these devices to last much longer than the 10-year warranty period.
The ARS-CLTM curb-opening screens effectively stop all trash and debris that is ¾” or greater from entering the catch basins during dry weather. These screens capture 85% to 90% of debris that typically flows into the catch basins, clog the 5mm holes of the CPS-ModTM screens, and impair their treatment capacity. The City’s street sweeping program then collects these pollutants. The CPS-ModTM Full Capture System is effective as the final lineof-defense when trash and debris escape past the ARS-CLTM screens during heavy storm events. The CPS-ModTM patented design stops 100% of particles 5mm or larger from exiting the catch basin and flowing downstream. This device is also certified by the State Water Board as a Full-Capture System.
Staff has evaluated G2’s Proposal and determined that the products produced by G2 (specifically, the CPS-MOD™ & ARS-CL™ Screens) are uniquely suited, proprietary products that will both fit within the City’s existing infrastructure and match existing facilities for the purposes of maintenance efficiency. The CPS-MOD™ & ARS-CL™ Screens are compatible with, and are an integral component of, the City’s existing infrastructure, and the continued use of the screens would facilitate the continuity of maintenance and support of its trash and debris capture devices.
The City’s Municipal Code Section 2.06.05.B.6 allows the City to make purchases from bids received by the County, State, or other public agency.
This process is sometimes known as “piggy-backing”, and allows the City to utilize the formal bidding results of other agencies when purchasing specialized equipment. G2 has been awarded a master agreement with the County of Orange (Contract No. MA-080-20011478) to furnish and install Trash and Debris Capture Devices on County-owned property (“County Agreement”). Section 15 of the County Agreement establishes a Regional Cooperative Agreement (RCA) that permits non-County public agencies to execute subordinate contracts for the same services during the effective dates of the County Agreement, which is currently through June 30, 2025. Under the County Agreement, the RCA terms, conditions, and pricing shall be extended to all subordinate contracts issued. The City’s agreement with G2, if awarded, is intended to be consistent with the terms, conditions, and pricing available through the County Agreement.
FISCAL IMPACT & PROCUREMENT REVIEW
The City’s adopted FY 2024-25 adopted budget includes an appropriation of $100,000 in Account #246-46-4600-8026 for the Trash Capture Filter Program. The quote from G2 Construction, Inc. for the purchase and installation of trash and debris capture devices utilizing pricing from the County of Orange’s Master Agreement is $100,000. This purchase will be made solely utilizing Measure W Safe Clean Water Program funds, with no impact to the City’s General Fund.
The purchase and installation of the trash and debris capture devices is in compliance with the City’s procurement policy, as the Department will be using a cooperative purchasing agreement in accordance with SMCC 02.06.05.B.6.
The Finance Director has reviewed this staff report for compliance with San Marino City Code §02.06.05.
