The Buzzards Bay Coalition earned Selectmen approval to protect roughly 5 1/2 acres of land on Burgess Point from future development.

Selectmen approved two, separate conservation restrictions for a 1 1/4-acre parcel near 33 Lydia's Island Road and a 4.4-acre parcel near 16 Winship Drive.

Both are owned by John Decas.

The designation permanently restricts development of private property by transferring rights from the landowner to a nonprofit or land trust, while the owner retains the deed.

The Coalition’s Director of Land Protection, Allen Decker, told the board the property will link two adjacent parcels also under conservation restrictions. Those parcels are owned by the Burgess Point Homeowners Association. He said there will be no public access to the site, save for four scheduled walking trips at different times of the year to view wildlife.

In total, 20 acres of land are now under protection on Burgess Point.

Decker said the area has been “designated a critical natural landscape” by the Natural Heritage & Endangered Species Program. The preservation effort is part of a larger Coalition plan that will rehabilitate the Onset Bathhouse. Earlier this year, Town Meeting voters approved spending $215,000 of Community Preservation Funds for the project. The total cost will be $2.1 million and the Coalition will privately raise the rest of the money.
