BACKGROUND
The State Water Resources Control Board (State Water Board), in coordination with nine Regional Water Quality Control Boards, implements 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 Stormwater Program regulates discharges from municipal separate storm sewer systems (MS4s) through the issuance of MS4 permits. For the Los Angeles region, the Los Angeles Regional Water Quality Control Board (Regional Board) adopted the 2012 National Pollutant Discharge Elimination System (NPDES) MS4 Permit, Order No. R4-2012-0175. The 2012 MS4 Permit was subsequently superseded by the 2021 Regional Phase I MS4 Permit, Order No. R4-2021-0105, which became effective September 11, 2021. The 2021 MS4 Permit establishes requirements for the County of Los Angeles, Los Angeles County Flood Control District, and participating cities within Los Angeles County, including the City of San Marino, to control discharges of stormwater and non-stormwater from their respective MS4s and reduce pollutants entering the region's receiving waters.

Among other requirements, the 2021 MS4 Permit requires Permittees to implement programs and measures to reduce pollutants discharged through their storm drain systems, including trash, debris, and sediment. These requirements are implemented on both an individual and watershed-wide basis and are intended to improve water quality in receiving waters, including rivers, creeks, and coastal waters. The City’s storm drain system ultimately discharges to the Upper Los Angeles River Watershed, and the City participates with other local agencies in regional watershed management and monitoring efforts to comply with the MS4 Permit.
In 2015, the State Water Board adopted Resolution No. 2015-0019, amending the Water Quality Control Plan for Ocean Waters of California (California Ocean Plan) to establish statewide requirements for controlling trash impacts to California's surface waters. The State Water Board determined that trash is a pervasive pollutant that adversely affects beneficial uses of surface waters, including wildlife and marine habitat and recreational uses. Because much of the trash entering surface waters originates on land and is transported through storm drain systems, the Resolution established a statewide narrative water quality objective and implementation requirements for trash control.
Consistent with these requirements, the 2021 MS4 Permit requires Permittees to implement trash control measures capable of capturing trash and litter down to five millimeters (5 mm) in size, subject to the requirements and implementation provisions of the Permit. These measures are intended to prevent trash and debris from entering receiving waters.
In 2018, Los Angeles County voters approved Measure W, which established the Safe Clean Water Program (SCWP) and authorized a special parcel tax of $0.025 per square foot of impermeable area on private property within the Los Angeles County Flood Control District. The SCWP provides dedicated funding for projects that increase regional water supply, improve water quality, and enhance communities throughout Los Angeles County. Forty percent of SCWP revenues are allocated to cities as local return funding. San Marino has received approximately $235,000 annually in local return funding over the past five years to address local stormwater and urban runoff needs.
On May 29, 2026, the City Council adopted the Fiscal Year 2026-27 Operating and Capital Improvement Program (CIP) budgets, including an appropriation of $225,000 in Account No. 246-46-4600-8026 for the City's Trash Capture Filter Program. Of this amount, $200,000 is proposed for the procurement and installation of trash and debris capture devices, with the remaining $25,000 reserved for County permitting and inspection costs.
DISCUSSION
The proposed project continues the City's ongoing program to retrofit catch basins with trash capture devices and reduce the amount of trash and debris discharged through the City's storm drain system. The City's catch basin retrofit program began in 2020, when ARS-CL™ curb-opening screens were installed in 72 City-owned catch basins by G2 Construction, Inc. The program continued during FY 2023-24, FY 2024-25, and FY 2025-26, resulting in the installation of an additional 133 devices in City-owned catch basins.
During the FY 2025-26 project, the City completed the retrofit of City-owned catch basins that were determined to be eligible for installation. The project also included field inspections and measurements of 134 County-owned catch basins located within the City. Although these catch basins are owned by the County, the City is responsible for retrofitting the facilities because they capture stormwater runoff generated within the City's jurisdiction.
Based on the field measurements and subsequent evaluation, 81 Countyowned catch basins have been identified as eligible for installation of fullcapture systems. G2 Construction, Inc. has submitted a proposal to fabricate and install the 81 systems for a total cost of $200,000. Upon completion of this project, all County-owned catch basins identified as eligible for a fullcapture system will have been retrofitted. Future phases will address Countyowned catch basins that were determined to be eligible for ARS-CL™ curbopening screens.
Trash Capture Devices
The City’s program has utilized two complementary proprietary trash capture devices manufactured and installed by G2 Construction, Inc.: the ARS-CL™ curb-opening screen and the CPS-Mod™ Full Capture Screen. The devices are custom fabricated to the specific dimensions and configuration of each catch basin or inlet. The systems are constructed of 304 stainless steel and are designed to integrate with the City's existing catch basin infrastructure.
The ARS-CL™ curb-opening screens are designed to intercept larger trash and debris before it enters the catch basin. By capturing a significant portion of debris during dry weather and smaller storm events, the screens help prevent larger materials from reaching and obstructing the downstream 5 mm fullcapture system. The City's street sweeping program collects much of the material intercepted by these screens.
The CPS-Mod™ Full Capture System serves as the final trash capture component within the catch basin. The system is designed to prevent particles 5 mm and larger from exiting the catch basin and continuing downstream. The CPS-Mod™ is certified by the State Water Board as a Full-Capture System.
Together, the systems provide a multi-stage approach to trash control that is compatible with the City's existing catch basin infrastructure and maintenance practices.
Procurement
Staff evaluated G2 Construction Inc.’s proposal and determined that the CPSMOD™ & ARS-CL™ systems are uniquely suited to the City’s existing infrastructure and established maintenance program. The devices are proprietary, custom-fabricated products designed to match the dimensions of individual catch basins. Continued use of these systems provides consistency with the City’s previously installed devices and reduces the need for difference equipment, maintenance procedures, and replacement components.
San Marino Municipal Code Section 2.06.05.B.6 permits the City to make purchases from bids received by the County, State, or other public agency.
This cooperative purchasing process allows the City to utilize the results of a formal solicitation conducted by another public agency when procuring specialized equipment and services.
G2 Construction Inc. has been awarded a master agreement with the County of Orange (Contract No. MA-080-25011708) for the furnishing and installation of trash and debris capture devices on County-owned property. Section 16 of the Additional Terms and Conditions of the County Agreement establishes a cooperative contract that permits other public agencies to execute subordinate contracts for the same services during the term of the agreement, currently through August 8, 2030. The cooperative contract provides for the extension of the applicable terms, conditions, and pricing to participating public agencies. The proposed City agreement with G2 Construction Inc. will utilize the terms, conditions, and pricing available under the County of Orange master agreement.
The proposed project will continue the City's phased approach to complying with applicable MS4 Permit trash-control requirements while spreading implementation costs over multiple fiscal years. Completing the eligible County-owned catch basin retrofits will further reduce the amount of trash and debris entering the storm drain system and ultimately the Upper Los Angeles River Watershed.
FISCAL IMPACT & PROCUREMENT REVIEW
The City's adopted FY 2026-27 budget includes an appropriation of $225,000 in Account No. 246-46-4600-8026 for the Trash Capture Filter Program.
G2 Construction, Inc.'s proposal for the fabrication and installation of 81 fullcapture systems is $200,000. The project will be funded entirely with Measure W Safe Clean Water Program local return funds and will have no impact on the City's General Fund. The remaining $25,000 of the budgeted appropriation is reserved for County permitting and inspection costs.
The proposed procurement is consistent with the City's procurement requirements. Pursuant to San Marino Municipal Code Section 2.06.05.B.6, the City may utilize the results of a formal solicitation conducted by another public agency through a cooperative purchasing arrangement. The proposed agreement with G2 Construction, Inc., will utilize the County of Orange's existing master agreement and associated pricing.
The Finance Director has reviewed this staff report for compliance with San Marino City Code §02.06.05.
