The Town of Wolfeboro hereby adopts this article pursuant to
the authority granted under RSA 674:16, in particular RSA 674:16,
II relative to innovative land use controls.
The purpose of this article is, in the interest of public health,
safety, and general welfare, to preserve, maintain, and protect from
contamination existing and potential groundwater supply areas and
to protect surface waters that are fed by groundwater. The purpose
is to be accomplished by regulating land uses which could contribute
pollutants to designated wells and/or aquifers identified as being
needed for present and/or future public water supply.
As used in this article, the following terms shall have the
meanings indicated:
AQUIFER
A geologic formation, group of formations, or part of a formation
that is capable of yielding quantities of groundwater usable for municipal
or private water supplies.

by tank vessel, pipeline, tank car, or tank vehicle and distributed
for the purposes of retail sale of gasoline.
GROUNDWATER
Subsurface water that occurs beneath the water table in soils
and geologic formations.
IMPERVIOUS
Not readily permitting the infiltration of water.
IMPERVIOUS SURFACE REQUIRED FOR STORING REGULATED MATERIALS
A surface through which regulated substances cannot pass
when spilled. Impervious surfaces include concrete, unless unsealed
cracks or holes are present. Asphalt, earthen, wooden, or gravel surfaces,
or other surfaces which could react with or dissolve when in contact
with the substances stored on them are not considered impervious surfaces.
JUNKYARD
An establishment or place of business which is maintained,
operated, or used for storing, keeping, buying, or selling junk, or
for the maintenance or operation of an automotive recycling yard,
and includes garbage dumps and sanitary landfills. The word does not
include any motor vehicle dealers registered with the Director of
Motor Vehicles under RSA 261:104 and controlled under RSA 236:126.
LICENSED PROFESSIONAL GEOLOGIST
A person who, by reason of advanced knowledge of geology
and the supporting physical and life sciences, acquired by education
and experience, is technically and legally qualified to engage in
the practice of geology as defined in this section and who has successfully
passed the examination as may be required in this section and who
is licensed by the Board or otherwise authorized to practice of the
profession of geology.
OUTDOOR STORAGE

which is cleared from roadways and/or motor vehicle parking areas,
is placed for disposal.
STRATIFIED-DRIFT/UNCONSOLIDATED SEDIMENT AQUIFER
A geologic formation of predominantly well-sorted sediment
deposited by or in bodies of glacial meltwater, including gravel,
sand, silt, or clay, which contains sufficient saturated permeable
material to yield significant quantities of groundwater to wells.
SURFACE WATER

or wellfield supplying a community public water system through which
contaminants are reasonably likely to move toward and reach such water
well or wellfield.
The Groundwater Protection District is an overlay district which
is superimposed over the existing underlying zoning and includes within
its boundaries the then current USGS Stratified Drift Aquifer Map
and the wellhead protection areas of community and municipal wells,
or as mapped on site by a professional geologist.
This article applies to all uses in the Groundwater Protection District, except for those uses exempt under §
175-26.3, Exemptions, of this article.
The following performance standards apply to all uses in the
Groundwater Protection District unless exempt under § 175-23.3:
A. For any use that will render impervious more than 15% or more than
2,500 square feet of any lot, whichever is greater, a stormwater management
plan shall be prepared which the Planning Board determines is consistent
with the Stormwater Management and Erosion and Sediment Control Handbook
for Urban and Developing Areas in New Hampshire, Model Ordinance Rockingham
County Conservation District, August 1992, and Best Management Practices
for Urban Stormwater Runoff, New Hampshire Department of Environmental
Services, January 1996.
B. Conditional uses, as defined under §
175-26.1, shall develop stormwater management and pollution prevention plans and include information consistent with Stormwater Management For Industrial Activities: Developing Pollution Prevention Plans and Best Management Practices. (US EPA, 1992). The plan shall:
(1) Demonstrate that the proposed use, either alone or on a cumulative
basis, will not cause a reduction of more than 10% of the long-term
volume of water (safe yield averaged over the last five years) contained
in the aquifer or the storage capacity of the aquifer.

prevention measures, the release of regulated substances into stormwater.
(3) Demonstrate that recharge to groundwater will not result in violation
of ambient groundwater quality standards (Env-Ws 410.05) at the property
boundary.
(4) Stipulate that expansion or redevelopment activities shall require
an amended stormwater plan and may not infiltrate stormwater through
areas containing contaminated soils without completing a Phase I Assessment
