This chapter will allow new concepts and innovative approaches
to housing and environmental design so that the Town's natural, scenic,
cultural, marine and historic resources may be preserved, thus meeting
the relevant objectives of the Comprehensive Plan, while limiting
the costs and impacts of development on the community and mitigating
the effects of climate change. Because Kittery's character is expressed
diversely through its natural environment comprising fields, forests,
rock outcrops, vernal pools, wetlands, salt marshes and shoreland
interwoven with its built environment, including both compact neighborhoods
and large-lot neighborhoods, conservation subdivisions in different
zones may necessarily differ in how they achieve this balance between
development and preservation. In all instances the objectives include:
A. Preservation of open space, including but not limited to farmland,
meadows, forests, and wildlife habitat as well as scenic views identified
in the Comprehensive Plan.
B. Preservation of areas with the highest ecological value as well as
areas with significant value not otherwise protected by law.
C. Location of buildings, streets and structures on those portions of
the site most appropriate for development based on environmentally
aware site design.
D. Connections to open space on adjoining lands wherever possible.
E. Reduction of impacts on water resources and water quality by minimizing
land disturbance and impervious surfaces while utilizing nature-based
strategies such as low-impact development (LID) combined with best
management practices (BMP) for optimal stormwater management.
F. Expansion of outdoor recreation opportunities wherever possible.
G. Preservation of historic, archaeological, and cultural features,
such as, but not limited to, historic structures, stone walls, cellar
holes, earthworks, middens or graves.
H. Minimization of residential developments' footprint, including streets,
utilities, and driveways, to lower the impact on the municipality,
neighboring properties and the natural environment.
I. Demonstrated awareness of and response to climate change effects
such as:
(1)
Sea level rise considerations where shoreland exists. Properties
that include coastal shoreland must show areas affected by 1.6 feet
and 3.0 feet of storm surge plus sea level rise utilizing data from
Maine Geological Survey or other sources as approved/adopted by the
Town, as well as any existing salt marsh and potential salt marsh
migration areas on the plans.
(2)
Utilization of nature-based adaptation strategies, such as low-impact
development (LID) for stormwater management and groundwater quality
and preservation of woodlands for wildlife, cooling effects and for
their role in carbon capture.
(3)
Energy efficiency and reduced greenhouse gas emissions in both
site design and building design.
(4)
Protection against salt water intrusion into freshwater drinking water supplies. Properties that include coastal shoreland or that are affected by tidal waters must demonstrate that proposed drinking water supplies are located beyond the potential reach [see Subsection
I(1) above] of salt water intrusion.
J. Conservation of the Town's natural resource and neighborhood diversity.
All development reviewed under this chapter is subject to the application procedures in Chapter
16.8, Subdivision Review, and the following:
A. In addition to the requirements of Chapter
16.8, the following items are required with submission of the sketch plan:
(1)
A plan showing the proposed conservation subdivision and a plan
showing a conventional subdivision for the site. Both plans must include
the following information, as applicable:
(a)
The location of each of the proposed building envelopes, as
well as the proposed placement of sidewalks, roads, service areas
and parking areas. Only developments having complete plans with building
envelopes shown will be considered.
(b)
Proposed dimensional measurements and sizes for all lots and
the dimensional standards required in the zone in which the development
will be located.
(c)
All land area identified in §
16.5.18, Net residential acreage, noted with total land areas for each applicable category.
(d)
Net residential density calculations demonstrating how many dwelling units are allowable based on the net residential acreage arrived at above and how many dwelling units are proposed. The number of dwelling units proposed must be the same for both the conventional subdivision and the conservation subdivision unless the conservation subdivision proposes to build or create affordable housing as described in §
16.10.9. In the uncommon circumstance where the number of proposed dwelling units differs between a conventional subdivision plan and a conservation subdivision plan without the affordable housing incentive involved, the smaller number of units prevails, no matter which type of subdivision is pursued.
(e)
Open space as described in §
16.10.7 of this chapter, labeled appropriately.
(f)
Natural features, with areas of ecological value noted, including
those identified by the Maine Natural Areas Program and Maine Inland
Fisheries and Wildlife, as well as all water bodies, streams, aquifers,
wetlands, vernal pools, salt marshes, floodplains, farmland, forested
and non-forested areas and scenic vistas.
(g)
Historical, archeological or culturally important features and/or
structures.
(2)
A map or plan showing constraints to development, such as, but
not limited to, wetlands, vernal pools, resource protection zones,
stream protection zones, shoreland zones, rare plant and animal habitat,
slopes in excess of 20%, easements, proposed or existing rights-of-way,
existing roads, driveway entrances and intersections, existing structures,
and existing utilities.
(3)
If the site includes valuable agricultural soils, such as, but
not limited to, prime farmland soils or soils of state-wide importance,
a soils map illustrating their locations must be included.
(4)
A written statement describing the site and the ways the proposed
development furthers the purpose and objectives of this chapter, including
how natural features will be preserved or enhanced.
(5)
If the conservation subdivision will rely on groundwater for
its drinking water supply, a written statement prepared by a hydrogeologist
must attest to the sufficiency and quality of water for the development
and that such a private well or wells will not reduce either the quantity
or quality of the groundwater supply for surrounding properties.
B. For preliminary plan submission, in addition to the requirements of Chapter
16.8, an applicant with a project that includes proposed public open space such as a park or a nature trail must obtain Town Council approval for accepting the public land prior to the Planning Board's preliminary plan approval. Such open space must be offered to the Town in fee or through an easement to be held by the Town. Town Council acceptance of the public open space is contingent upon receipt of final plan approval by the Planning Board.
C. An applicant with a project that includes moderate to high value
wildlife habitat or other exceptional natural features is strongly
encouraged to seek a conservation easement to be held by a land trust
or other such conservation entity. Such easements will be counted
towards the open space requirements for the subdivision as reserved
open space and must be approved by the Planning Board.
D. The Planning Board may, at the applicant's expense, seek expert and
professional opinions concerning any aspect of the proposed development,
including, but not limited to, engineering, site evaluation/septic
design, landscaping, natural resources, historic resources, traffic,
wetlands, soil, stormwater and water quality.
Prior to the beginning of any site work, including tree cutting
or disturbing any soil, the applicant must:
A. Clearly define the limits of clearing and obtain sign-off from Code
Enforcement per approved plan; and
B. Schedule a pre-construction meeting with the Town and file all required performance guarantees and inspection escrows in forms acceptable to the Town Manager in accordance with §
16.8.11F.
