Control Measures

Control Measures

To meet trash reduction goals, municipalities are using a combination of control measures. These actions have led to reductions in trash that accumulates on streets and sidewalks, enters the storm drains, and flows to the creeks and the Bay.

Trash Full Capture Devices (FCDs) and Partial Capture Devices (curb screens)

West Valley municipalities have installed over one hundred full capture devices in public storm drain inlets. All municipalities must perform O&M yearly to keep FCDs operating properly to control trash.

Street Sweeping

All four municipalities provide weekly, monthly, or quarterly street sweeping which significantly diverts trash and other pollutants from reaching storm drains.

Source Control

Jurisdiction-wide actions to reduce trash at the source such as the Single-Use Plastic Bag Ban and Expanded Polystyrene Food Service Ware Ban.

On-land Trash Cleanup and Creek Cleanups

Municipal staff maintains medians, sidewalks, landscaped areas, roads, and parks and trails for trash control. Also, Campbell, Los Gatos, and Saratoga work with volunteer groups for additional trash cleanups near creeks, highway interchanges, parks, and streets. Campbell coordinates multiple homeless encampment cleanups each year with assistance from Valley Water. 

Trash Container Management

New trash and recycling containers are added, as needed, in public places, in parks and sidewalks. Private property owners are notified by the Authority's inspector where complaints are received, or staff observes commercial sites where trash containers are overflowing.

On-land Visual Assessments

Assessment to demonstrate effectiveness of each municipalities combination of control measures takes place each year when SCVURPPP conducts On-land Visual Trash Assessments at multiple sites in each jurisdiction. SCVURPPP provides most of the data needed for the annual report.

Receiving Water Monitoring

Development and testing of the trash receiving water monitoring program occurred through a regional project coordinated through the Bay Area Stormwater Management Agencies Association (BASMAA) and in coordination with the Trash Monitoring Methods Project, California Ocean Protection Council and State Water Board project that is being administered via the Southern California Coastal Water Research Project (SCCWRP) and the San Francisco Bay Estuary Institute (SFEI). Consistent with MRP requirements, the final report for the development and testing of the Bay Area trash receiving water monitoring program was submitted by BASMAA on July 1, 2020, following peer review.
