The Bethel Island Municipal Improvement District, through the elected Board of Directors and Staff, will serve the people of Bethel Island by responding to the needs and concerns of the public by allocating the available resources to maintain a safe and secure levee system, by maintaining a free flowing drainage system and by creating and maintaining a park and recreation facility.

The Bethel Island Municipal Improvement District (BIMID) was formed in the early 1960's by the California State Legislature. The Island is not a city and thus has to rely on a combination of private and county public services.

BIMID is a special act district that has powers similar to a city. BIMID currently provides levee maintenance and repairs, habitat mitigation, park services, as well as storm drain maintenance and repair.

  • The Bethel Island Municipal Improvement District was created by the California State Legislature in 1960 and absorbed Reclamation District 1619.
  • The acreage was described as 3516.54 acres in the unincorporated territory of Contra Costa County.
  • It is an island below sea level of 7 to 15 feet surrounded by 11.5 miles of earthen levee that keeps the Taylor, Piper, Dutch and Sandmound Slough waters out.
  • Access to Bethel Island is by boat or the new bridge on the south side that connects Bethel Island Road to Cypress Road to Highway 4 in Oakley.
  • Funding for the District is ad valoreum tax collected by the County that is used to compete for State funding from the Dept. of Water Resources.
  • Work is handled by one full time equipment operator and two (2) secretaries, one full time and one part time, plus the 5 elected directors.
  • The main function is to improve and maintain the levee system and then to keep the drainage system adequate to remove seepage and rain water.



They are stocked with sand and sandbags (no shovels this year). Locations have an orange traffic cone marking the locations. There are 3 sandbag station locations:

    • End of Taylor Road (by New Life Marina)
    • Bethel Island Road (at entrance to BIMID Mitigation Site)
    • Piper Road (Almost to Willow Road at BIMID gate to Mitigation Site)
If there aren’t any sandbags, please call the BIMID Office 925 684-2210 and the locations will be restocked.


Please help minimize the need for spraying by properly maintaining the vegetation along the water front of your property. No spray will be applied to those properties where property owners have maintained the levee top and water side vegetations.

Unfortunately, BIMID is no longer able to accept vegetation, wood or other material that has been removed from the levee. The Pittsburg Transfer Station located at 1300 Loveridge Road in Pittsburg accepts vegetation, wood and many other items. They are open 7 days a week, from 7am to 6 pm. For more information regarding the Pittsburg Transfer Station please call (925) 473-0180. We apologize for any inconvenience.
