All developments shall incorporate soil erosion and sediment
control programs phased according to the scheduled progress of the
development including anticipated starting and completion dates.
The applicant shall submit a natural resources plan as outlined
under the development review provisions of this title which shall
clearly establish the means of controlling soil erosion and sedimentation
for each site, or portion of a site when developed in stages. The
soil erosion and sediment control measures shall have the approval
of the Soil Conservation Service pursuant to the Soil Erosion and
Sediment Control Act (Ch. 251, P.L. 1975).
Control measures shall apply to all aspects of the proposed
land disturbance and shall be in operation during all stages of the
disturbance activity. The following principles shall apply to the
soil erosion and sediment control plan:
A. Stripping of vegetation, grading or other soil disturbance shall
be done in a manner which will minimize soil erosion;
B. Whenever feasible, natural vegetation shall be retained and protected;
C. The extent of the disturbed areas and the duration of its exposure
shall be kept within practical limits;
D. Either temporary seeding, mulching or other suitable stabilization
measures shall be used to protect exposed critical areas during construction
or other land disturbances;
E. Drainage provisions shall accommodate increased runoff resulting
from modified soil and surface conditions during and after development
or land disturbance;
F. Water runoff shall be minimized and retained on-site wherever possible
to facilitate groundwater recharge;
G. Sediment shall be retained on-site; and
H. Diversions, sediment basins, and similar required structures shall
be installed prior to any on-site grading or land disturbance.
All necessary erosion and sediment control measures installed
under these provisions shall be adequately maintained for one year
after completion of the approved plan or until such measures are permanently
stabilized as determined by the engineer. The engineer shall give
the applicant, upon the applicant's request, certification of this
determination.
Each tract shall have a soil erosion prevention plan to accompany
the development plan which shall show temporary sedimentation basin(s)
through which stormwater will be directed during periods of temporary
ditching, and final contours. In addition, the plan shall outline
general construction stages to illustrate what portion(s) of the site
will be unprotected at various stages, the maximum amount of land
to be exposed at various stages, the availability and use of water
trucks to prevent dust and erosion by wind, areas where topsoil will
be stockpiled during construction, the areas where it will be redistributed
after completion of the applicable stage of construction, the methods
of seeding the topsoil while it is stockpiled and again after its
redistribution, and a plan of progressing toward completion of the
entire project that shall outline how and at what stages and approximate
times the previously exposed areas will be final graded and seeded
or paved, or by some other means have the soil stabilized prior to
completion of the entire project so that permanent soil erosion prevention
methods will be employed at the earliest possible time.
The excavation and grading for completion of a development shall
be done in accordance with the approved plan which contains soil erosion
and sediment control provisions. Excavation of soil, other than required
for the construction of approved structures and supporting facilities,
such as but not limited to streets, driveways and parking areas, shall
be prohibited. Regrading of property so as to redistribute topsoil
throughout the site from areas excavated for such approved structures
and supporting facilities shall be permitted, but shall be done in
the following manner to minimize or eliminate the erosion of soil.
Any application proposing the disturbance of more than 5,000 square
feet of surface area of land as defined in the Soil Erosion and Sediment
Control Act (Ch. 251, P.L. 1975) shall include on its plan the following: the means to
control or prevent erosion, provide for sedimentation basin(s) for
soil that does erode due to water, and control drainage, dust and
mud on the premises as well as abutting lands; the preservation of
soil fertility and the resulting ability of the area affected to support
plant and tree growth by maintenance of adequate topsoil consisting
of at least six inches of the original layer; maintenance of necessary
lateral support and grades of abutting lands, structures and other
improvements; prevention of pits and declivities which are hazardous
or which provide insect breeding locations; the physical limitations
and characteristics of the soil shall not be altered to prevent the
use to which the land may lawfully be put; and such other factors
as may reasonably bear upon or relate to the public health, safety
and general welfare.
