The San Diego Chapter's primary sub-entities are Groups, Committees, and Sections. Groups are formally recognized by the Club with geographical boundaries and have more stringent requirements than committees and sections. The two groups are North County and North County Coastal. Club members automatically become a member of the Group in their geographical area, similar to automatic membership in their Chapter. Committees work to address a particular area of Club or Chapter interest.
Members volunteer their time to work on the committee issue.
Many committees, including the Executive Committee, don't have separate bylaws. Some committees, particularly the Conservation Committee, have their own sub-committees addressing more granular areas of interest. Sections form to unite members sharing common intests so they may share activities together. Membership is optional and Sections may charge for membership.
