A.
Statement of purpose.
(1)
The purpose of the Floodplain Management, Wetland
Resource Conservation Overlay District is to regulate land development
within flood hazard zones, wetlands and the Kayderosseras Creek area
basin. Population growth, attended by housing, roads and other construction,
along with increased demands on the Town's natural resources, has
been found to be encroaching on, despoiling or eliminating many of
the Town's wetlands, water bodies, watercourses and other natural
resources and processes associated therewith.
(2)
The conservation, preservation and maintenance of
these natural resources in any undisturbed and natural condition constitutes
important physical, ecological, social, aesthetic, recreational and
economic assets necessary to promote the health, safety and general
welfare of present and future residents of the Town and of downstream
drainage areas.
(3)
It is the intent of this district to provide for the
protection, preservation, proper maintenance and use of the Town's
water bodies, watercourses and wetlands by preventing or minimizing
erosion due to flooding and stormwater runoff, flooding of downstream
lands, maintaining the natural groundwater supplies, and preserving
and protecting the purity, utility, water-retention capability, ecological
functions, recreational usefulness and natural beauty of all water
bodies, watercourses and wetlands and other related natural features
of the terrain.
(4)
Specifically, the following objectives pertain:
(a)
To maintain, protect and enhance water quality
and associated aquatic resources and water supply within the Kayderosseras
Creek watershed.
(b)

applies to all areas up to 50 feet inland from the normal high-water
mark and paralleling the shoreline. Where the natural vegetation is
removed, it is to be replaced with other vegetation that is equally
effective in retarding erosion and preserving natural beauty. The
total width of any opening to the shore shall not exceed 40 feet.
(b)
Tree cutting for noncommercial purposes is permitted,
provided that no more than 50% of existing trees six or more inches
in diameter, measured at five feet above ground level, are removed
from any contiguous stand or grouping of trees. In no case shall the
area of contiguous clearing exceed 7,500 square feet.
(3)
Erosion and sedimentation control.
(a)
On slopes greater than 15%, there shall be no
grading or filling within 100 feet of the normal high-water mark,
other than for road construction or water crossings, except to protect
the shoreline and prevent erosion.
(b)
