Section 30A. Whoever removes stones, gravel, sand or other material from any natural barrier on land bordering on the sea, which barrier furnishes protection to such land and adjacent upland against erosion by the sea shall be punished by a fine of not more than five hundred dollars.
The superior court shall have jurisdiction in equity to enforce the provisions of this section. A petition for such enforcement may be filed by the attorney general, the selectmen of the town or the mayor of a city in which such barrier is located, or any person who may suffer damage in his property by such removal.
