As used in this chapter, the following terms
shall have the meanings indicated:
ABUTTER
The owner(s) of land sharing a common property line with
the owner of land that is the subject of an application and the owners
of land directly opposite on any public or private street or way,
and abutters to the abutters within 300 feet of the property line
of land that is the subject of the application as they appear on the
most recent applicable tax list, notwithstanding that the land of
any such owner is located in another city or town.
AGRICULTURE

or aquacultural use, as defined by the Massachusetts Wetlands Protection
Act (MGL C. 131, § 40) and its implementing regulations
(310 CMR 10.00) and any agricultural activity which is consistent
with an approved soil conservation plan prepared or approved by the
United States Department of Agriculture (USDA) Natural Resources Conservation
Service.
ALTERATION
Any activity that will measurably change the ability of a
ground surface area to absorb water or will change existing surface
drainage patterns. Alteration may be similarly represented as "alteration
of drainage characteristics," and "conducting land disturbance activities."
Such changes include: change from distributed runoff to confined,
discrete discharge; change in the volume of runoff from the area;
change in the peak rate of runoff from the area; and change in the
recharge to groundwater on the area.
APPLICANT
Any "person" as defined below requesting a stormwater management
permit for proposed land-disturbance activity.

BEST MANAGEMENT PRACTICE (BMP)
Structural, nonstructural and managerial techniques that
are recognized to be the most effective and practical means to prevent
and/or reduce increases in stormwater volumes and flows, reduce point
source and nonpoint source pollution, and promote stormwater quality
and protection of the environment. "Structural" BMPs are devices that
are engineered and constructed to provide temporary storage and treatment
of stormwater runoff. "Nonstructural" BMPs use natural measures to
reduce pollution levels, do not require extensive construction efforts,
and/or promote pollutant reduction by eliminating the pollutant source.

by a qualified professional engineer (PE), a professional land surveyor
(PLS), a registered landscape architect (RLA), or a certified professional
in erosion and sedimentation control (CPESC), which includes best
management practices or equivalent measures designed to control surface
runoff, erosion and sedimentation during pre-construction and construction-related
land disturbance activities.
GRADING
Changing the level or shape of the ground surface.
GRUBBING
The act of clearing land surface by digging up roots and
stumps.
