body
BACKGROUND INFORMATION:
The City is permitted by the State Water Board to discharge stormwater into the Mokelumne River under the statewide general permit for small municipal storm sewer systems (referred to as MS4s).
The State has mandated that all trash (items as small as a cigarette) be collected prior to discharging to rivers or streams, and has specified a compliance deadline of December 2030. Trash that blows out of overfilled garbage cans (or littered) gets washed into our storm drain system and discharged into the river if it is not captured prior. Approximately one-third of the City's storm drainage system ends up discharging into the Mokelumne River.
This project installed a trash capture device in the storm drain line in River Point Circle (see attached Exhibit A). The device will filter trash as small as a cigarette butt from the storm drain system before it is discharged into Mokelumne River. This project was the fifth phase of the stormwater trash collection projects.
On November 19, 2025, the Council approved plans and specifications for this project, and authorized the City Manager to award the contract to the lowest bidder and execute change orders in a combined amount not-to-exceed $600,000 (Resolution 2025-199). The bid opening was held on December 17, 2025 and the City received the following two (2) bids:
