according to the SCS method, periodically saturated during the growing season
or remains wet for long periods.
POOR WATER QUALITY
Water which fails to meet Department of Environmental Protection
standards for cleanliness, either in drinkability or aesthetics.

protection to further minimize the risk of unreasonable adverse effects:
(1)
Within the primary recharge area of a public drinking water supply or
potential public drinking water supply.
(2)
Within 200 feet of any identified private drinking waters supply well.
(3)
Within 100 feet of any standing or flowing water.

zones stated in the purpose section of this chapter.
SILTATION
Particles of minerals, soils, etc., which creep or flow into wetland
areas or other areas where they are not indigenous to the area.
SOILS
Organic and inorganic compositions consisting of silicates of aluminum,
iron, calcium, magnesium, silica, etc., derived from the original rock by
weathering and producing characteristic soil types; also decomposed plants
and animals as a result of microorganisms. Air, water and environmental factors
also contribute to soils. Soils are used in determining wetland areas through
their potential for support of wetland plant species as well as their inability
to drain wetland areas freely.
STORM DAMAGE PREVENTION
The prevention of damage caused by water from storms, including,
but not limited to, erosion and sedimentation, damage caused by flooding,
waterborne debris or waterborne ice.
STREAM
A body of running water, including brooks and creeks, which moves
in a definite channel in the ground due to a hydraulic gradient and which
flows within, into or out of an area subject to protection under the chapter.
A portion of a stream may flow through a culvert or beneath a bridge. Such
a body of running water which does not flow throughout the year (i.e., which
is intermittent) is a stream, so long as it receives discharge from groundwater
for periods of time such that it may be observed to flow during times when
there is no surface water discharge occurring.
SWAMP
Areas where groundwater is at or near the surface of the ground for
a significant part of the growing season or where runoff water from surface
drainage frequently collects above the soil surface, and where a significant
part of the vegetational community is made up of, but not limited to, nor
necessarily includes all of the following plants or groups of plants: alders
(Alnus), ashes (Fraxinus), azaleas (Rhododendron canadense and R. Viscosum),
black alder (Ilex verticillata), black spruce (Picea mariana), buttonbush
(Cephalanthus occidentalis), American or white elm (Ulmus americans), white
Hellebore (Veratrum viride), hemlock (Tsuga canadensis), cowslip (Caltha palustris),

TRIBUTARY
Any body of water which in turn flows into another body of water
and so on until it terminates in a significant water body.
VEGETATED WETLANDS
Areas where the topography is low and flat and where the soils are
annually saturated. The boundary of vegetated wetlands is the line within
which the vegetational community is substantially characterized by species
identified in the Wetlands Protection Act or this chapter, or, when vegetation
appears to have been altered, within which hydric soils are present. The types
of vegetated wetlands are: wet meadows, marshes, swamps and bogs. The Commission
may find, based on substantial evidence in a particular case, that additional
species are characteristic of wetlands.
VEGETATION
Plant life included on federal, state and local wetland protection
acts known as "wetland species."
VERNAL POOL
Shall be the same as in the Wetlands Protection Act; however, if
a vernal pool is identified and certified within 90 days of filing a notice
of intent, such vernal pool shall be afforded full protection under this chapter.
VERY POORLY DRAINED
Water is removed from the surface so slowly that the free water remains
on the surface during most of the growing season.
WATER SUPPLY
Shall refer to any raw or finished water source that is presently
used, reserved for future use or under investigation for future use by the
City as a public water system as defined in 310 CMR 22.02 or used as a source
of private drinking water by one or more persons. This shall include all land
and waters used as or tributary to a public water system except those exempted
under 310 CMR 22.20.
WATER TABLE
The upper limit of the portion wholly saturated by water.
WILDLIFE
All species of animals otherwise than domesticated of any of the
several classes indigenous to the City for any period of time throughout the
year.
WILDLIFE HABITAT
Land and/or water areas which support any animals in a wild (not
domestic) state, including, but not limited to: birds, amphibians, four-legged
animals and insects. Depending on the wildlife, the range can be a few yards
to a few miles in area. Plant community composition and structure, hydrolic
regime or other characteristics provide important food, shelter, migratory
travel or overwintering areas for these wildlife species over an indefinite
time period.
