GUIDELINES
Disposal
Beach Nourishment
i. Beach nourishment shall be conducted such
that:
a) The beach is not widened
beyond its historical profile. The historical profile shall be
defined as the widest beach profile that existed prior to June
1986.
b) The material placed on the beach consists of sand of equal
or greater grain size than the sand existing on the beach.
c) Placement and subsequent erosion of the materials does not
adversely impact tidal marshes or productive intertidal and shallow
subtidal areas.
d) Efforts shall be made to maintain a stable beach profile.
e) Dredged material shall be graded at a uniform slope and contoured
to reduce cove and peninsula formation, to minimize juvenile
fish stranding and hazards to beach users.
f) Erosion or deposition downstream from the disposal site is
minimized. Particular care must be taken that erosion of the
dredged material does not smother marsh or other shallow productive
areas.
g) The volume and frequency of dredged material disposal is such
as to maintain a stable beach profile, as nearly as possible.
