Section 12 of said chapter 44B, as so appearing, is hereby amended by striking out subsection (a) and inserting in place thereof the following subsection:-
(a) A real property interest that is acquired with monies from the Community Preservation Fund shall be bound by a permanent restriction, recorded as a separate instrument, that meets the requirements of sections 31 to 33, inclusive, of chapter 184 limiting the use of the interest to the purpose for which it was acquired. The permanent restriction shall run with the land and shall be enforceable by the city or town or the commonwealth. The permanent restriction may also run to the benefit of a nonprofit organization, charitable corporation or foundation selected by the city or town with the right to enforce the restriction. The legislative body may appropriate monies from the Community Preservation Fund to pay a nonprofit organization created pursuant to chapter 180 to hold, monitor and enforce the deed restriction on the property.
