Three Western Massachusetts cities adopted the Community Preservation Act during Tuesday’s election. The measure provides funding for affordable housing and open space projects, as well as to help save historic buildings.

The CPA, as it’s widely known, adds on a small surcharge to property tax bills in order fund local projects. This makes cities and towns eligible for matching state funds.

Voters in Springfield, Holyoke and Pittsfield adopted the measure.

John Dickson is with the group Preserve Pittsfield, which supported the ballot question.

“We probably missed out on $1 million-plus in the last ten years, since we last had it on the ballot, of state funds, that could have been used to save a couple of very high-profile buildings that we’ve lost in the last year,” Dickson said.

Some opponents said the CPA is a tax increase the falls on the backs of home owners. And voters in South Hadley and Palmer rejected it by narrow margins.
