An initial announcement that was recently made that a full (8 cycle) 3 minute emergency siren drill was to be conducted at 11:00 am on Wednesday, October 7, 2015, shortly after the regular monthly 2 cycle (45 second) siren test.  However, this October 7 drill has been called off to give the BIMID Board further opportunity at its regular October 15, 2015, meeting to evaluate the siren system.  In the event that the Board still intends thereafter to go ahead with the drill, it will take place at 11:05 am on Wednesday, November 4, 2015, and subsequent community notice will be provided well in advance.

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!”

 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.
