MassGIS Data: Community Preservation Act (CPA) Projects

This point layer identifies the locations of Community Preservation Act projects undertaken in eligible communities. Shapefile download, with data as of June 2022, was updated on August 15, 2023.

Table of Contents



The Massachusetts Community Preservation Act (CPA) was signed into law by former Governor Paul Cellucci and Lt. Governor Jane Swift on September 14, 2000 (Chapter 267 of the Acts of 2000). The CPA has been amended several times. The CPA allows communities to create a local Community Preservation Fund to raise money through a surcharge of up to 3% of the real estate tax levy on real property for open space protection, historic preservation and the provision of affordable housing. The act also creates a significant state matching fund, which serves as an incentive to communities to pass the CPA.

In the summer of 2007 the EEA, MassGIS and Community Preservation Coalition worked together to create an online version of the CP-3 form which communities complete to give information on projects that the CPA funds. Part of the online submission form is a map to locate a point for the project (if the project has a geographic component). The existing project database was cleaned up and new projects were entered using the tool to catch up the list. The online CP-3 form also allows communities to update information on older projects.

The layer is stored in ArcSDE as CPA_PROJECTS_NEW_PUB.

*NOTE: Approximately half of CP-3 projects have an associated point. Projects without points are not included in this datalayer. Visit the Community Preservation Coalition to access a public database of all CP-3 project information.*


Some points were created by MassGIS, others by the Community Preservation Coalition or town Community Preservation Committees based on an address. Not every project has a single geographic component (and some have more than one).

This datalayer only contains Community Preservation Act projects that have associated points.

Please contact the municipality's CPA committee for more information about projects

These data are updated on an on-going basis by town Community Preservation Committees through an online data entry tool. Also see the Community Preservation Act (CPA) Towns layer, which provides information on municipalities that have adopted the Community Preservation Act.

Project data from forms submitted by the cities and towns during the Spring-Summer submission period will be reviewed by the CPAC and then returned to MassGIS for publication in the Fall.
