[Amended 3-13-2001 ATM; 3-9-2010 ATM by Art. 4]
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.
A. 
Exempt subdivisions. A subdivision shall be exempt from the conservation subdivision requirement if the Director of Planning and Development determines that the proposal meets one of the criteria set forth below. If the Director determines that a subdivision is exempt, the Director shall provide written notice to the applicant, all abutters, the Chair of the Planning Board, and the Chair of the Conservation Commission within five business days after making the determination. An applicant, an abutting property owner, or the Conservation Commission may appeal the Director's determination to the Planning Board. The appeal shall be made in writing within 30 days of the Director's determination. The Planning Board shall hold a public hearing on the appeal. The review by the Planning Board shall be based upon the materials submitted to the Director and the testimony at the public hearing. The Planning Board may affirm or change the decision of the Director. Until the appeal is decided, the Planning Board shall not process an application for the approval of a conventional residential subdivision for the subject site.
B. 
Exemption criteria. The Director of Planning and Development shall find that a proposed subdivision is exempt from the requirement that a subdivision be developed as a conservation subdivision only if the proposed subdivision meets one of the following criteria. In determining if the criteria are met, any lot that has been or will be transferred to a qualified conservation organization as such term is defined in Section 170(h)(3) of the Internal Revenue Code of 1986 (code) or any successor section, and the regulations promulgated thereunder, which organization is organized and operated primarily for one of the conservation purposes specified in Section 170(h)(4)(A) of the code, and will be restricted to conservation use in perpetuity, shall not be counted as a lot for the purpose of this provision.
[Amended 3-13-2012 ATM by Art. 4]

Side and rear yard setbacks for dwelling unit sites shall be flexible to allow for the consideration of proximity of other building sites, landscape and topography, adjacent open space, and view protection.
(3) 
A minimum distance of 20 feet shall be maintained between buildings on separate lots. A minimum distance of 20 feet shall be maintained between buildings on the same lot.
F. 
Discretionary density bonuses. Additional density may be allowed by the Board when one of the following public benefits is proposed:
(1) 
Public usage of open space: a maximum density bonus of 10% shall be permissible when public open space is provided to address critical recreational or conservation needs.
(2) 
Provision for affordable housing: IZIP provisions shall be permissible.
G. 
Buffer area.
(1) 
A buffer area consisting of open and undeveloped land shall be maintained along the perimeter property boundary(ies) of the original tract. Use of the buffer area shall be limited to conservation open space or limited use open space. The Planning Board may, upon a finding that the objective for the buffer is met, allow active use open space and road rights-of-way within the buffer areas.
(a) 
Tracts 10 acres to 50 acres: Buffer areas must be a minimum of 50 feet in depth.
(b) 
Tracts greater than 50 acres: Buffer areas must be a minimum of 100 feet in depth.
(2) 
Buffer areas may be part of separately designated lots or building areas and must be clearly designated on the plan as such with a notation indicating the specific uses permitted within the buffer area.
(3) 
Shore front buffer. A buffer area shall be created to include land within 100 feet of the mean high-water mark of all lake or pond shore front property.
H. 
Open space.
(1) 
A minimum of 50% of the total tract area, excluding road rights-of-way or easements, shall be required to be permanently dedicated as open space.
(2) 
The Planning Board shall require that all environmentally sensitive areas be dedicated as conservation open space.
(3) 
Sensitive area disturbance. The proposed design shall strictly minimize disturbance of environmentally sensitive areas. Lands within the one-hundred-year floodplain, wetlands or having slopes in excess of 25%, and rock outcroppings constitute such environmentally sensitive areas, where disturbance shall be strictly minimized. Demonstration by the applicant that these features will be protected by the proposed application shall be prerequisite to approval of both the conceptual preliminary plan and the detailed final plan.
(4) 
The applicant shall submit a proposal for the use of the remainder of the required open space. The Board shall then determine, upon consideration of the character of the land, the type of development, the location of the development, the surrounding neighborhood and the proximity of adjacent open space uses, the proportion of the open space to be limited use open space and active open space.
(5) 
In Shore Front Residential District areas, including buffer areas, a minimum of 50% of the land area shall be required to be permanently dedicated as limited use or conservation open space. The Planning Board may require permitted uses in the active open space within the Shore Front Residential District Buffer Area to be clustered and may limit the amount of beach area and the number and type of docks.
(6) 
Conservation lands shall be laid out in general accordance with Wolfeboro's Master Plan Natural Resource Chapter Maps to ensure that an interconnected network of open space will be provided.
I. 
Conceptual long-range development plan. When a conservation subdivision will not utilize the entire parcel and there is potential for future subdivision or development of the parcel or any of the lots being created, the application for subdivision approval shall include a conceptual long-range development plan showing the potential utilization of the lots and the balance of the parcel not being subdivided. The long-range plan is intended to be conceptual in nature, to rely on published data about natural resources relevant to the parcel and the built environment, and to demonstrate that the current subdivision proposal will not compromise important conservation values or the long-term development of the parcel as a conservation subdivision. This plan shall show the relationship of the proposed subdivision area to the balance of the parcel and to adjacent land. This plan shall analyze the conservation and development potential of the remaining area of the parcel and shall show, in general terms, the potential street network, open space areas, and development areas in a manner that demonstrates that both the proposed development and the future development can occur so that it conforms to the requirements for conservation subdivisions and preserves the significant natural resource and conservation values of the entire parcel.
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.
