Definitions. As used in this subsection:
ACCRETION
Includes the accumulation of sediment by natural or human-induced
means on the beach area. "Natural accretion" is the buildup of land
solely by action of the forces of nature on a beach by deposition
of waterborne or airborne material. "Artificial accretion" is a similar
buildup of land by reason of a human act, such as accretion formed
by a breakwater or beachfill deposited by mechanical means.
BEACH AREA
Gently sloping areas of sand or other unconsolidated material
that extends landward from the mean high water line to either: the
vegetation line; a manmade feature generally parallel to the ocean
such as a retaining structure, bulkhead or road; or the seaward foot
of dunes, whichever is closest to the ocean waters.
DEVELOPMENT RESTRICTION LINE
An artificial boundary delineating the extreme limit of allowable
development along the shore inland of the existing dune fields and
beaches.
DUNE AND SHORELINE MAP
A topographic survey of dunes and beaches. The survey will
contain, but not be limited to the following information: the dune
crestline, dune ridges, and the landward and seaward edge of the dunes.
The Map shall be reviewed and revised to reflect any changes every
two years and following any storm which damages large portions of
the dune area.
DUNE AREA
Area between the seaward edge of the dune and the landward
edge of the dune. This shall include all areas within the following
districts: Dune Maintenance District, Dune Restoration District, and
Dune Reconstruction District. This area is considered to have dynamic
boundaries which move in response to seasonal winds and storms. Consequently,
the boundaries shall be reviewed at least every two years and following
any storm which damages large portions of the dune area. The boundary
review process will be conducted by the Municipal Engineer, the Department
of Public Works, and assistance and review by representatives of the
New Jersey Department of Environmental Protection.
DUNE CONSULTANT
An expert on dunes and their care retained by the borough.
In any periods which no such expert is regularly retained, it shall
mean such other person designated by the Board of Commissioners or
reliance upon the New Jersey Department of Environmental Protection
at no fee.
DUNE CREST
The point or line where the dune's highest elevation
is located.
DUNE MIGRATION LINE
The line inland of the most landward edge of the dune area.
The line is delineated on the Dune and Shoreline Map. This area is
considered to have dynamic boundaries which move in response to seasonal
winds and storms. Consequently, the boundaries shall be reviewed every
five years.
DUNE VEGETATION
All plant species found on beaches and dunes of northeastern
U.S., either native or introduced, which can build and stabilize sand
dunes. Specifically, it shall include, but not be limited to, such
species as American beachgrass (Ammophila brevigulata), sea rocket
(Cakile edentula), seaside spurge (Euphorbia polygonifolia), dune
cordgrass (Spartina patens), sea goldenrod (Solidago sempervirens),
dusty miller (Artemisia stelleriana), bayberry (Myrica pennsylvanica),
beach pea (Lathyrus japonicus), salt spray rose (Rosa rugosa), beach
plum (Prunus maritima), etc., which normally grow or may be planted
on the slopes of the dunes or behind them, with no distinction being
made as to how such plants are introduced into their location.
DUNES
A wind or wave deposited or manmade formation of sand (mound
or ridge), that lies generally parallel to, and landward of, the beach
and the foot of most inland dune slope. "Dune" includes all landward
dune ridges and mounds, the foredune, secondary, and tertiary dune
ridges, as well as manmade dunes, where they exist.
(a)
A formation of sand immediately inland from the beaches which
is stabilized by retaining structures, and/or snow fences, planted
vegetation, and other measures are considered to be dunes regardless
of the degree of modification of the dune by wind or wave action or
disturbance by development.
(b)
A small mound of loose windblown sand found in a street or on
a part of a structure as a result of storm activity is not considered
to be a "dune." (This definition is intended to reflect the definitions
set forth in CAFRA regulations N.J.A.C. 7:7E-3.16 as it may be amended
from time to time.)
EROSION
The wearing away of land by the action of natural forces.
On a beach, the carrying away of beach materials by wave action, tidal
currents, littoral currents or by wind.
MEAN HIGH WATER LINE
The line found by the intersection of a plane at the elevation
of mean high water with the existing slope of the beach.
MEAN SEA LEVEL
The average height of the sea surface, based on observations
of all stages of the tide over a nineteen-year period in the United
States.
PATHWAY
An improved, protective access way, at grade across the dune.
PERSON
Natural persons, partnerships, firms, associations, joint-
stock companies, syndicates and corporations and any receiver, trustee,
conservator or other officer appointed pursuant to law or by any court,
state or federal. "Person" also means the State of New Jersey, counties,
municipalities, authorities, other political subdivisions and all
departments and agencies within the aforementioned governmental entities.
SAND FENCE
Shall include the term "snow fence" of a barricade type established
in a line or a pattern to accumulate sand and aid in the formation
of a dune, such as picket type consisting of light wooden fence, four
feet in height, held together by wire and affixed to wooden posts.
SEAWARD EDGE OF DUNE
The intersection line of the foreslope of the dune and the
gradient of the beach area, or vegetation line, or the upper driftline,
whichever is the more easterly.
VEGETATION LINE
That line connecting the most seaward naturally occurring
perennial plants with other such plants.
WALKWAY
A constructed means of crossing the dune area in accordance
with approval by the borough.
