The fund could support numerous existing and new projects throughout the town for years to come.
On Friday and Saturday, a team from Helensburgh Community Development Trust and their partners will be holding a meeting with information on their proposals, including their plans for a community wind farm which would generate cash for the Fund.
Members of the Trust will be on hand to explain how the Trust and Common Good Fund would operate.
Green Cat Renewables, who have been brought in by the Trust to develop the wind farm proposals, will also be there to answer questions. The exhibition is free, open to all, in the Pillar Hall of The Victoria Halls, Helensburgh from 3pm to 8pm on both days.
