About Flood Control Channel Maintenance
The Alameda County Flood Control and Water Conservation District (ACFCD) helps protect residents and property from flooding through the planning, design, construction, and maintenance of flood control facilities such as natural creeks, channels, pipelines, pumps, and levees. ACFCD also works to prevent storm water pollution and educates citizens about actions they can take to create a healthier environment.
Sediment excavated from channels is used to build or create wetlands to provide vital wildlife habitat. Other components of this maintenance program include:
- Constructing levees to protect properties from the effects of climate change and sea level rise
- Installing recreational trails on the tops of the levees
- Ongoing studies to understand the effects of climate change and sea level rise on Alameda County
Channel Maintenance Program
Safe, efficient, and sustainable flood control conveyance channels are essential to minimizing flood risk to public and private properties, and protecting habitat and water quality. To this end, ACPWA channel maintenance program including desilting, debris removal, catch basin and trash capture device maintenance and erosion repair are designed to achieve the desired objectives.
The County has two large in-line trash capture devices currently installed and draining large land areas of Ashland and Cherryland. Device 1 is located in the Estudillo Canal at Washington Avenue and drains 1,600 acres of Ashland. Device 2 is located in the storm drain line next to Meekland Avenue at San Lorenzo Creek and drains 433 acres of Cherryland.
The County installed and maintains 37 small catch basin trash capture devices. These devices are located in communities of San Lorenzo and Castro Valley and drain a much smaller area (1-2 acres each). In order to maintain compliance with the County’s Municipal Regional Stormwater Permit (MRP) trash reduction requirements, the Public Works Agency will be installing more trash capture devices in the County’s unincorporated area over the next few years.
