Flood Zone 4 Maintenance Update, Summer 2022

Posted on September 7, 2022


The Marin County Flood Control and Water Conservation District conducts regular maintenance activities throughout the year in each of the diverse Flood Control Zones in Marin. The various forms of maintenance work, whether it is for flood mitigation infrastructure or targeted vegetation control, is a critical part a flood risk reduction for each respective community.

In Flood Control Zone 4, which covers portions of Tiburon, preventative maintenance at all pump stations takes place every year and includes the inspection, testing, and as needed replacement of electrical and mechanical components. Additionally, individual pumps and motors are typically removed and serviced for major preventive maintenance on a six-year interval at each of the Zone’s three stations. The #1 pump at Pamela Ct Pump station was removed for service, repair, and refurbishment in June. It will be reinstalled the week of September 12.
The East Creek access road was mowed this past spring. The week of September 19, the Conservation Corps North Bay will trim cattails and remove any low or downed branches in the channel at East Creek. Additionally, the Corps will clean debris from West Creek and the Karen Way Trash Rack.

Sediment and cattail root removal for East Creek is planned for the last week of September or early October. Sediment and cattail root masses will be removed along East Creek between Karen Way and approximately 100 feet downstream of the Cecilia Way crossing.

In addition to these maintenance activities, District crews check the trash rack at Karen Way, the Cecelia way creek crossings, and the trash racks at the pump stations before, during, and after storms.

Flood District staff will be posting maintenance updates to the Bel Aire neighborhood via Nextdoor as work progresses during September and October. For questions, please email Marin County Flood Control District.

  • Don’t rake leaves into the street, please use your green container. Leaves and yard debris left in the street will clog street drains and cause localized flooding.
  • Clean out the drainage structures on your property, such as rain gutters and drain grates. Do this in advance of a storm and in a safe manner, don’t wait for the rain to start falling.
  • Register with Alert Marin to received urgent news and notifications during emergency situations. Resources: https://www.marinsheriff.org/services/emergency-services/alert-marin
