The Martha's Vineyard Times West Tisbury considers $300,000 Proposition 2½ override Budget uncertainties, lack of flexibility, and use of free cash necessitates higher override amount. West Tisbury is looking at a $300,000 override in order to keep from cutting it too close on the budget. In order to build reserves in the townâs budget, West Tisbury selectmen are considering a $300,000 Proposition 2½ override. At a meeting of the West Tisbury board of selectmen Wednesday, town accountant Bruce Stone said the financial management team recently conducted a review on the projection for the tax levy next year. He said that at that point in time, the town was looking at an approximately $300,000 override. Since that time, Stone said, selectmen agreed to reduce several warrant articles through the use of stabilization funds for a total of $100,000. Additionally, altered premiums from the Cape Cod Municipal Health Group allowed the town and the schools to drop their budgets by a total of $155,000, Stone said.
