[Adopted 10-28-1963]
All grades of roads in subdivisions adjoining waters within Dennis shall
be not less than six (6) feet above the mean high water of lakes, ponds, streams,
tidal water, flats and all tributaries of such tidal waters and flats. Foundations
of dwellings shall be not less than two (2) feet above the lowest point of
the road or roads adjoining each lot.
[Amended 9-15-1969]
On land adjoining lakes, ponds, streams, tidal waters, flats and all
tributaries of such tidal waters and flats, sewage disposal systems shall
comply with the Commonwealth of Massachusetts Sanitary Code XI, and said systems
shall terminate not less than seventy-five (75) feet from a point at least
two (2) feet above mean high water or a greater height where conditions warrant
it. All sewage disposal permits refused by the Building Inspector shall be
reviewed by the Board of Health.
[Adopted 9-4-1984]
Septic sewage systems shall not be installed in any area of a buildable
lot where there are active shifting sands or earth. This shall include:
A.
Coastal beaches, to include any unconsolidated sediment
subject to wave, tidal and coastal storm action which forms the gently sloping
shore of a body of salt water and includes tidal flats. Coastal beaches extend
from the mean low-water line landward to the dune-line, coastal bank line
or the seaward edge of existing man-made structures, when these structures
replace one (1) of the above lines, whichever is closest to the ocean.
B.
Coastal dunes, to include any natural hill, mound or
ridge of sediment landward of a coastal beach deposited by wind action or
storm overwash. "Coastal dune" also means sediment deposited by artificial
means and serving the purposes of storm damage prevention or flood control.
C.
Barrier beaches, to include any low-lying strip of land
generally consisting of coastal beaches and coastal dunes extending roughly
parallel to the trend of the coast It is separated from the mainland by a
narrow body of fresh, brackish or saline water or a marsh system. A barrier
beach may be joined to the mainland at one (1) or both ends.
D.
Coastal banks composed of unconsolidated
sediments, to include the seaward face or side of any elevated land form,
other than a coastal dune, which lies at the landward edge of a coastal beach,
land subject to tidal action or other wetland. These banks are exposed to
vigorous wave action and, through that action, serve as a major continuous
source of sediment for beaches, dunes and barrier beaches as well as other
land forms caused by coastal processes. Coastal banks with previously existing
man-made structures, such as seawalls, riprap, revetments and bulkheads, are
exempt from this provision.
