Tips for Planning Board Members for review of noncommercial small-scale
docks, piers and similar structures accessory to residential use
The Planning Board routinely receives applications for Chapter 91 applications for general licenses. These
applications are typically for noncommercial small-scale docks, piers and similar structures accessory to
residential use.
Massachusetts General Law Chapter 91, the waterways licensing program, is The Commonwealth's
primary tool for protection and promotion of public use of its tidelands and other waterways .
310 CMR 9.00 is administered by the Department of Environmental Protection (DEP) under the authority
of M.G.L. Chapter 91, § 18 to establish procedures, criteria, and standards for uniform and coordinated
administration of the provisions of M.G.L. Chapter 91.
Massachusetts General Law Chapter 91 §18C & 310 CMR 9.29 refer to noncommercial small-scale docks,
piers and similar structures accessory to residential use and the Planning Board’s role.

are utilized only for water-dependent uses or otherwise serve a proper public purpose;
(c) Protect the public health, safety, and general welfare as it may be affected by any project in tidelands, great ponds,
and non-tidal rivers and streams;
(d) Support public and private efforts to revitalize unproductive property along urban waterfronts, in a manner that
promotes public use and enjoyment of the water; and
(e) foster the right of the people to clean air and water, freedom from excessive and unnecessary noise, and the
natural, scenic, historic, and esthetic qualities of their environment unde r Article XCVII of the Massachusetts
Constitution.
