Bethel Island Municipal Improvement District


Update 2/27/17


It has been brought to BIMID’s attention that as of now the following marinas on the island are no longer available as evacuation points:

  • New Life Marina – 1200 Taylor Road
  • Caliente Harbor Marina – 1550 Taylor Road
  • Frank’s Marina – 7050 Riverview Drive
  • Old Lundborg Landing – 6777 Riverview Drive
  • Piper Pointe Marina – 3667 Willow Road

It is very important to understand in the case of a breach of the levee, YOU WILL NEED TO GET TO THE TOP OF THE LEVEE AS SOON AS POSSIBLE.  If you can’t readily get to the levee top, go up to the second story of your house (or if yours is a single story home, the second story of a nearby neighbor’s house).  IT WILL BE IMPERATIVE FOR YOU TO GET TO THE HIGHEST POINT THAT YOU CAN ABOVE THE FLOODPLAIN.  IT IS ALSO CRITICAL THAT YOU DO NOT DRIVE ON THE LEVEE IN ITS SATURATED CONDITION FOLLOWING ALL THE STORMS.

BIMID WORK NOTICE (

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.


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.

Spread the word, tell your neighbors!!!  Do the deed and remove the weeds!

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.  They charge $40.50 per ton and the minimum charge is $22.50. Prices are subject to change, please contact the station for updates. They accept cash, visa and mastercard.  For more information regarding the Pittsburg Transfer Station please call (925) 473-0180.  We apologize for any inconvenience.

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.
