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.
There are a total of nine (9) phases required in order to comply with the State’s requirement, and the City has completed four (4) of the phases already. Staff is prioritizing locations by high risk land uses (as required by the State), size of outfall, and size of drainage area. Phase 5 is proposed to cover the forty-four acres served by Outfall Drainage Area 5. The remaining cost of this program is estimated at $3.2 million, over the next 4 years and is included in the Wastewater Enterprise Financial Plan.
This proposed project will install a trash capture device upstream of the Outfall No. 5 discharge point, as shown on Exhibit A. The device will be approximately 6 feet in diameter and 18 feet in depth, with only a manhole opening visible at the surface. The plans and specifications are on file in the Public Works Department. The planned bid opening date is December 10, 2025. The project estimate is $520,000.
Staff recommends approving plans and specifications, authorize advertisement for bids for 2025 Stormwater Trash Collection Project - Phase 5 and adopt a resolution authorizing the Interim City Manager to award Contract to lowest responsive bidder and execute change orders in a combined amount not-to-exceed $600,000.
STRATEGIC VISION:
5C. Infrastructure: Address deferred maintenance.
FISCAL IMPACT:
This project will slightly increase annual storm drainage maintenance costs for the trash capture device. This project will not impact the General Fund.
