Board Members

David Clemmer


Dave has lived in Sebastopol since 1964 and he and his family have lived in Graton since 2007. As a new community member he became aware of the Graton Community Services District (GCSD) and began attending public meetings in 2010. During this time, he became concerned about the fiscal sustainability of the District and began asking hard questions at the meetings as a concerned community member.

Dave bring 40+ years as a retired ASE Certified Master Heavy Equipment Mechanic and extensive expertise in assessing equipment and reading blueprints to his role with the District. Dave began exploring various waste water treatment plant models and touring several within California. In talking general managers from throughout the region he learned of options which he shared with GCSD to determine if other models could benefit the local sewer district.

Sworn in as a board member January 2015, Dave was elected Board President in August 2015. Today, Dave brings his knowledge and his interest in learning from others to his role as GCSD Board President. As a new Board member, Dave’s focus was on improving the fiscal health of the District which had a budget deficit of nearly $450,000.

Today with a balanced budget, Dave now focuses on rekindling relationships with neighboring districts and identifying opportunities for collaboration, always with an eye on fiscal responsibility. Going forward Dave will continue to actively collaborate with GCSD General Manager and Treatment Plant Operators while knowing that his role is to represent Graton residents while ensuring fiscal sustainability, transparency and environmental stewardship for GCSD.
