The mission of our owners' association is to enhance the community through social events, communication, beautification, and historic preservation. The DPOA is run by community volunteers and funded by annual contributions from our residents.
Formed in 1929, it is one of the oldest such organizations in California. Though our owners' association possesses no legal power, it acts as a sounding board and works with other organizations to facilitate community affairs.

To guarantee that Diablo would forever be recognized as a distinct entity, Robert Noble Burgess petitioned the U.S. Postmaster General for a Post Office. The Diablo Post Office opened in 1917, inside the original Cook mansion at 1925 Alameda Diablo. Over the years, it moved to several locations around our community (see pictures hung in the Post Office). In 1974, the former Golf Pro Shop at Diablo Country Club was dedicated as the Diablo Post Office. Many residents, in partnership with the DPOA, DCSD and Diablo Country Club, have worked together over the last 100 years to protect this mainstay of connection for our community.
In the early days, there were no street addresses in Diablo; all the houses had names and mail was addressed to Name, Diablo, California. The USPS still does not provide home mail delivery in Diablo, so residents rent P.O. boxes. Other courier services, such as Fed Ex and UPS, can deliver direct to homes. Residents can also use the Post Office address for package delivery. Example how to use our post office for delivery address: Name, 1701 El Nido, #___, Diablo, CA 94528
If you've been told by Contra Costa County that your project requires "Historic Review", please contact The Diablo Municipal Advisory Council (DMAC). The DMAC is the authority that officially represents our community on matters of planning and zoning within Diablo to the Contra Costa County Planning Commission and Board of Supervisors. The five-member council is made up of the DCSD Board members. You can find more information at www.diablocsd.org
The Diablo Community Services District (DCSD) is a California special district that was formed in 1969 for the purpose of providing security services, maintaining roads, culverts, bridges and the equestrian/pedestrian path known as Kay’s Trail (between Alameda Diablo and Mt. Diablo Scenic Blvd). These activities are supported by property taxes paid by Diablo property owners to Contra Costa County. Five directors, residents of the community who serve without compensation, govern the DCSD. They are elected for four-year terms on a staggered basis. Board meeting agendas, minutes, financial documents, ordinance code, security and road information, alerts, upcoming events and contact information for the board of
directors can be found on the website at
Meetings are held the second Tuesday of each month at 7:30 p.m. at the Diablo Country Club. All residents are invited to attend. The current meeting agenda is posted in the Post Office display case for DCSD 96 hours in advance of the meeting and on the website at www.diablocsd.org
Since 1971, the DPOA has been recognizing residents who do exceptional work in our community by honoring them as Citizen of the Year. Thank you for making our community the special place that it is.
