3. The Diamond A Independents; "Independents," 35 parcels

4. Each of the five Diamond A Ranch Estates subdivisions has its own set of Covenants, Conditions and Restrictions (CCRs)

5. The Diamond A Ranches has its own set of CCRs

Community Organizations

Over the years, several organizations have been created that enhance the cohesiveness of Diamond A. Click on the name of any of the organizations listed below for more details.

Diamond A Neighborhood Association (DANA)
DANA represents the Diamond A community in interactions with agencies outside of our community. DANA also performs a number of administrative activities within our community.

Architectural Review Committee (ARC)
In support of DANA's mission, the Architectural Review Committee (ARC) is charged with reviewing all building permit requests and assessing the compatibility of each request with the applicable Diamond A CCRs and Sonoma County permit requirements, including the Taylor/Sonoma/Mayacamas Mountains Development Guidelines. These County guidelines apply to all properties in Diamond A.

Diamond A Recreation Association (DARA)
The Diamond A Recreation Center on Spring Drive acts as the focus of social and recreational activities in our community. Despite similar acronyms and a largely overlapping membership,  DARA and DANA have distinct roles to play.

Diamond A Mutual Water Company (DAMWCO)
The DAMWCO maintains the water supply for most of the properties in our community.

Grove Street Fire Safe Council (GSFSC)
The GSFSC is a volunteer organization dedicated to promoting wildfire risk reduction, and helping the communities to prepare for wildfire. The development of a Community Wildfire Protection Plan in 2020 launched GSFSC's formal activities. 

Diamond A Trail Safe
In September, 2023 a group of Diamond A residents formed the Trail Safe volunteers, dedicated to restoring and maintaining the recreational easements to an even higher standard so that they form effective "covered fire breaks."
