AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for
Stormwater Trash Collection Project — Phase 2 (2021)
MEETING DATE: April 7, 2021
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for
bids for Stormwater Trash Collection Project — Phase 2 (2021).
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.
Staff anticipates a total of 10 phases in order to comply with the State's requirement with one phase
constructed so far. Staff is generally prioritizing locations by high risk land uses (as required by the
State), size of outfall, and size of drainage area. The second phase is proposed to cover the 140 -acre
drainage area of Outfall No. 4. The total cost of this program is estimated at $6.5 million, over the next
10 years and is included in the Wastewater Enterprise Financial Plan.
The project will install a trash capture device upstream of the Outfall No. 4 discharge point, as shown on
Exhibit A. The device will be approximately 11 feet in diameter and 18 feet in depth, with only a manhole
opening visible at the surface. The specifications are on file in the Public Works Department. The
planned bid opening date is May 5, 2021. The project estimate is $350,000.
FISCAL IMPACT: This project will slightly increase annual storm drainage maintenance costs
for the trash capture device.
FUNDING AVAILABLE: Funding will be identified at project award.
