The fund can only be tapped for large capital projects, such as the construction of a new public safety building, with town meeting approval.
Regular property taxes from the slot machine parlor and harness racetrack will go into the general fund for use in the budget.
"The opening of Plainridge Park Casino this spring is going to bring much needed revenue and jobs to the Plainville community, and creating this fund, on behalf of the town, will ensure that revenue from Plainridge are used appropriately," said state Sen. Richard Ross.
"The Town of Plainville and its elected officials are to be commended for taking such a proactive and responsible approach to this new revenue. I am glad I could be a part of creating this fund, which will set Plainville up to grow and thrive for many years to come," said state Rep. Shawn Dooley.
