BACKGROUND On November 29, 2018, the City entered into a Cooperative Agreement with Caltrans for the installation of a trash capture device at the Koll Center Parkway storm drain outfall into the Arroyo del Valle. As part of Caltrans' 1-680 ramp improvement project, Caltrans was obligated under the National Pollutant Discharge Elimination System (NPDES) General Permit (Order No. 2012-0011-DWQ; as amended: 2014-0077-DWQ) to provide trash load reductions. As constructed, the storm drains serving the Caltrans property connects directly to the City's system which flows to the Arroyo del Valle. Since Caltrans was having a difficult time determining how to accomplish trash capture at the system connection points, they approached the City with an idea to install a larger device downstream in the City's storm drain system that would achieve their legal requirements, and also provide value to the City. Working together, the City and Caltrans identified the mutually beneficial location to install the device at the outfall of the Koll Center Parkway storm drain system, which would capture trash in stormwater runoff from Caltrans' property and from the Koll Center Business Development, helping the City meet the NPDES Municipal Reginal Permit (Order No. R2-2015-0049) requirements for trash reduction. The agreement outlined the City would own and operate the system, and that Caltrans would provide a total of$300,000 towards the installation of the system. Under an on-call general civil engineering contract with CSG, City staff issued a task authorization on November 8, 2019, for $29,850 for a review of available trash capture devices and creation of the biddable set of plans, specifications and estimates for the installation of a trash capture device in the chosen location. The design included a review of four trash captures devices approved by the State Water Board and identified BioClean by Forterra as the recommended device. The device fit within the available storm drain easement, had the shallowest depth of the four structures, met the maintenance access requirements, and had the lowest cost. During the design study, it was identified that a geotechnical investigation report should be conducted to provide the necessary information for the shoring design due to the 18- foot excavation depth needed for the installation of the unit. On January 7, 2020, Amendment No. 1 was issued for $17,700 to CSG, adding the geotechnical investigation report conducted by their subconsultant, BSK and Associates Inc. (BSK). During the design of the project, an additional scope of services was requested by the City for another device to be reviewed, for the coordination and modification of the trash capture unit to meet maintenance demands, and for the addition of a connector pipe screen. On February 10, 2021, Amendment No. 2 was issued for $6,060 to cover the additional design services. The total design services cost is $53,610, which includes the anticipated bid and construction support services cost of$6,425. The plans and specifications were completed in January 2021 and the project was advertised for construction bids on January 13, 2021. The bid period closed on February 9, 2021, with ten contractors submitting a bid by the deadline. DISCUSSION The NPDES General Permit requires regulated projects to include trash capture devices to reduce the trash load to the environment. Similarly, the current San Francisco Bay Page 2 of 4
