A.
Resource Protection District. In the interest of wise land use, public health, convenience, safety and welfare, the regulations of this district are intended to guide the use of areas of land with extended periods of high water tables:
(1)
To further the maintenance of safe and healthful conditions and the general welfare, and to protect spawning grounds and other wildlife habitat.
(2)
To avoid pollution of wetlands which feed into brooks, streams, lakes, ponds and rivers.
(3)
To protect, preserve and maintain the water table and water recharge areas within the Town so as to preserve present and potential water supplies for the public health and safety of the Town.
(4)
To prevent the destruction of natural wetlands which provide flood protection and stormwater storage, recharge of groundwater supply and augmentation of stream flow during dry periods.
(5)
To prevent unnecessary or excessive expenses to the Town to provide and maintain essential services and utilities which arise because of inharmonious use of wetlands.
(6)
To encourage those uses that can be appropriately and safely located in wetland areas.
(7)
To protect presently existing natural wetland and wildlife habitat.
(8)
To protect the stormwater capacity of freshwater wetlands to minimize flooding downstream.
B.
Shoreland District. The regulations of this district are intended to accomplish the following purposes:
(1)
To control building sites in shoreland areas which are already densely developed, to prevent further undue encroachment upon water bodies.
(2)
To control the use and development of undeveloped shoreland areas and to provide maximum protection to the land and water resources so that:
(a)
The processes of eutrophication, sedimentation and pollution, leading to the ultimate degradation or destruction of the water body, will be eliminated or delayed as long as possible.
(b)
The process of accelerated nutrient enrichment of water bodies, which almost always accompanies shoreland development, will be kept at a minimum.
(c)
Water bodies, particularly those with public access, will be maintained in a condition fit for the present and future use and enjoyment of the public.
(3)
To provide minimum standards, as a stopgap measure, until such time as research establishes precisely the susceptibility of various water bodies to degradation, and the exact nature of the effect of shoreland development on that degradation process.
(4)
To enhance the enjoyment and use of water bodies through the protection of fish and aquatic life from destruction that results from advanced stages of man-induced eutrophication.
(5)
To minimize expenditures of public moneys for flood control projects.
(6)
To minimize rescue and relief efforts undertaken at the expense of the general public.
(7)
To minimize flood damage to public facilities such as water mains, sewer lines, streets and bridges.
C.
Stream Protection District. The regulations of this district are intended to accomplish the following purposes:
[Amended 3-9-1991 ATM by Art. 53]
D.
General Purpose District. The regulations of this district are intended to accomplish the following purposes: to allow a maximum diversity of uses while protecting farmland, the public health and safety, environmental quality and economic well-being of the Town, by imposing minimum controls on those uses which, by virtue of their external effects (waste discharge, noise, glare, fumes, smoke, dust, odors or auto, truck or rail traffic), could otherwise create nuisances or unsafe or unhealthy conditions.
E.
Floodplain District.
(1)
The regulations of this district are intended to accomplish the following purposes:
(a)
To provide that lands in the Town of Shapleigh subject to seasonal and periodic flooding as described hereinafter shall not be used for residence or other purposes in such a manner as to endanger the health, safety or welfare of the occupants thereof, of the public generally, or so as to burden the public with costs resulting from unwise individual choices of land use.
(b)
To assure the continuation of the natural flow pattern of the watercourse(s) within the Town, in order to provide adequate and safe floodwater storage capacity to protect persons and property against the hazards of flood inundation.
(2)
The Floodplain District shall be considered as overlying other districts. Any uses permitted in the portions of the districts so overlaid shall be permitted, subject to all the provisions of this section.
