301 CMR 25.05
DPA Boundary Maps
(1) Maps. Maps showing DPA boundaries currently in effect are available from CZM.
(2) Boundary Delineation. Except as otherwise deemed appropriate by the Director, DPA
boundaries shall coincide to the maximum extent practicable with roadways, property lines, or
other physical or legal landmarks that are generally permanent and can be ascertained with
relative ease through field observation or inspection of scaled maps available from municipalities
or other government sources. Notwithstanding any other provision of 301 CMR 25.00, CZM
may make minor adjustments of an existing DPA boundary to facilitate its identification in
relation to such physical or legal landmarks, provided however that such adjustments generally
should not result in a net reduction in the total area of the DPA. Unless otherwise specified in
a designation decision issued pursuant to 301CMR 25.00, any public or private way serving as
the boundary of a DPA shall be included in its entirety.
(3) Boundary Determinations. It is the exclusive responsibility of CZM to formally interpret
the DPA boundary maps to determine whether any specific parcel or portion thereof is included
in a DPA. Any person who desires a boundary determination shall submit a written request to
CZM and shall provide copies of the request to DEP and to such other persons as CZM may
require.
