The purpose of this article is to allow an alternative to the
basic provisions of conventional residential subdivision practices.
This alternative encourages the environmentally sound development
of land and provides for the preservation of open space, the protection
of natural resources and the creation of attractive living environments
and provides for a diversity of lot sizes, building densities and
housing choices to accommodate a variety of age and income groups
and residential preferences, so that the community's population diversity
may be maintained.
In order to achieve the purpose of this article, the specific
objectives are to:
A. Allow flexibility and creativity in design and efficiency in the
siting of services and infrastructure, including the opportunity to
reduce length of roads, utility runs and the amount of paving required
for residential development.
B. Discourage development sprawl and consumption of rural and/or agricultural
land. To protect areas of the community with productive agricultural
soils for continued or future agricultural use by conserving blocks
of land large enough to allow for efficient farm operations.
C. Create residential environments which provide adequate open space
amenities adjacent to living areas.
D. Facilitate the economical, efficient and environmental provision
of public services.
E. Provide a more efficient use of land in harmony with its natural
characteristics.
F. Preserve usable contiguous open space, agricultural land, tree cover,
recreation areas, scenic vistas, undeveloped lengths of shore front
and wildlife habitats.
G. Conserve open land, including those areas containing unique and sensitive
natural features such as woodlands, steep slopes, streams, floodplains,
wetlands, wildlife corridors and winter deer yards by setting them
aside from development.
H. Provide multiple options for landowners in order to minimize impacts
on environmental resources (sensitive lands such as wetlands, floodplains
and steep slopes) and disturbance of natural or cultural features
(such as mature woodlands, tree lines, critical wildlife habitats,
historic buildings and fieldstone walls).
I. Conserve scenic views and elements of the Town's rural character
and minimize perceived density by minimizing views of new development
from existing roads.
J. Reduce erosion and sedimentation by the retention of existing vegetation
and the minimization of development on steep slopes.
K. Implement adopted Town policies to conserve a variety of irreplaceable
and environmentally sensitive resource lands as set forth in the Town's
Master Plan.
The conservation subdivision option shall be required in all
residential districts when the parcel size noted below has been met:

Where specific development requirements are addressed in this
article, they shall supersede any other Town regulation. Where specific
development requirements are not addressed in this article, the most
stringent of any other Town regulation shall apply.
The development of land under this article is deemed a subdivision
under RSA 674:35.
A. Proposal review. The proposal shall be reviewed by the Planning Board
to meet all of the provisions provided for under RSA 674:36, II, as
the Board deems applicable. In addition, development proposals shall
be reviewed under the procedures and requirements of the Subdivision
Regulations, as amended. The Board shall consider the special nature of this type of development and shall determine prior to approval that the purpose and objectives in §§
175-146 and
175-147 above have been met.
B. Ownership. The tract of land may be held in single and separate ownership
or in multiple ownerships. However, when a tract is held in multiple
ownerships, it shall be planned as a single entity with common authority
and common responsibility.
C. Site suitability. As evidenced by the Existing Resources/Site Analysis
Map, the conceptual preliminary plan and the final plan, the tract
incorporating this design option shall be suitable for supporting
development in terms of environmental conditions, its size and its
configuration.
D. Legal document requirement and review. The Board shall require any
and all legal associations, agreements, and documents considered necessary
to assure that the objectives of this article are met. This may include
but not be limited to:
(1)
A homeowners' association;
(5)
Development improvement agreements;
(6)
Conservation easement; and
(7)
Financial securities for development improvements.
E. Conservation land.
(1)
Conservation land that is required to be reserved and created
through the subdivision process shall be subject to permanent conservation
easements prohibiting future development and defining the range of
permitted activities. For example, the clearing of woodland habitat
shall generally be prohibited, except as necessary to create trails
and active recreation facilities or to install subsurface septic disposal
systems.
(2)
All conservation land shall be permanently restricted from future
subdivision and development.
F. Maintenance. Unless otherwise agreed to by the Town, the cost and
responsibility of maintaining common facilities and open space shall
be borne by the property owner, condominium association, homeowner
association, or conservation organization.
Preexisting structures on the original tract designated for
open space residential development may be incorporated within the
design. Structures falling within buffer areas may remain in their
existing location. Existing dwelling units must be incorporated in
the overall density calculations.
