The following definitions shall apply in the interpretation
and implementation of this chapter. Additional definitions may be
adopted by separate regulation.
ALTER
Any activity that will measurably change the ability of a
ground surface area to absorb water, will change existing surface
drainage patterns, or will increase or decrease the rate or volume
of flow from a site.
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.
BETTER SITE DESIGN
Site design approaches and techniques, including low-impact
development (LID) that can reduce a site's impact on the watershed
through the use of nonstructural stormwater management practices.
Better site design includes conserving and protecting natural areas
and green space, reducing impervious cover, using natural features
for stormwater management, and providing site-wide infiltration.
DEVELOPMENT
Any construction that disturbs or alters a parcel of land.
DISTURBANCE OF LAND
Any action causing removal of vegetation or a change in the
position, location, or arrangement of soil, sand, rock, gravel or
similar earth material.
ILLICIT CONNECTION
A surface or subsurface drain or conveyance which allows
an illicit discharge into the Georgetown storm drain system regardless
of whether said connection was previously allowed, permitted or applied
for before the effective date of this bylaw.
[Added 5-1-2023 ATM by Art. 13]
ILLICIT DISCHARGE
Direct or indirect discharge to the Georgetown storm drain system that is not composed entirely of stormwater, including and without limitation, sewage, processed stormwater, or wash water, except as exempted in §
57-7 of this bylaw or in implementing regulations.
[Added 5-1-2023 ATM by Art. 13]
INFEASIBLE
Not technologically possible, or not economically practicable
and achievable in light of best industry practices.
[Added 5-1-2023 ATM by Art. 13]
INFILTRATION
The act of conveying surface water into the ground to permit
groundwater recharge and the reduction of stormwater runoff from a
project site.
LOW-IMPACT DEVELOPMENT (LID)
An ecosystem-based approach to land development and stormwater
management that ensures that each development site is designed to
protect, or restore, the natural hydrology of the site.
MASSACHUSETTS STORMWATER MANAGEMENT STANDARDS
The latest version, as may be amended from time to time,
of the Stormwater Management Standards and accompanying Stormwater
Handbook issued by the Department of Environmental Protection pursuant
to authority under the Wetlands Protection Act, MGL c. 131, § 40,
and the Massachusetts Clean Waters Act, MGL c. 21, §§ 26
through 53. The Stormwater Management Standards are incorporated in
the Wetlands Protection Act Regulations, 310 CMR 10.05(6)(k), and
the Water Quality Certification Regulations, 314 CMR 9.06(6)(a).
MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4) or MUNICIPAL STORM
DRAIN SYSTEM
The system of conveyances designed or used for collecting
or conveying stormwater, including any road with a drainage system,
street, gutter, curb, inlet, piped storm drain, pumping facility,
retention or detention basin, natural or man-made or altered drainage
channel, reservoir, and other drainage structure that together comprise
the storm drainage system owned or operated by the Town of Georgetown.
NONPOINT SOURCE POLLUTION
Pollution from many diffuse sources caused by rainfall, snowmelt,
or other method of pollutant transport moving over and through the
ground. As the runoff moves, it picks up and carries away natural
and human-made pollutants, finally depositing them into water resource
areas.
NORMAL MAINTENANCE
Activities that are regularly scheduled to maintain the health
and condition of a landscaped area. Examples include removal of weeds
or invasive species, pruning, mowing, raking, and other activities
that are done at regular intervals within the course of a year.
POST-DEVELOPMENT
The conditions that reasonably may be expected or anticipated
to exist after completion of the land development activity in accordance
with approved plans on a specific site or tract of land. Post-development
refers to the phase of a new development or redevelopment project
after completion, and does not refer to the construction phase of
a project.
PRE-DEVELOPMENT
The conditions that exist prior to the proposed disturbance
activity. Where phased development or plan approval occurs (preliminary
grading, roads and utilities, etc.), the existing conditions at the
time prior to the first plan submission shall establish pre-development
conditions.
RECHARGE
The replenishment of underground water reserves.
REDEVELOPMENT
Development, rehabilitation, expansion, demolition, construction,
land alteration, or phased projects that disturb the ground surface,
including impervious surfaces on previously developed sites. The creation
of new areas of impervious surface or new areas of land disturbance
on a site constitutes development, not redevelopment, even where such
activities are part of a common plan which also involves redevelopment.
[Amended 5-1-2023 ATM by Art. 13]
RUNOFF
Rainfall or snowmelt water flowing over the ground surface
or other source which may result in transport of pollutants.
SITE
The extent of development and/or redevelopment activities,
including but not limited to the creation of new impervious cover
and improvement of existing impervious cover.
[Amended 5-1-2023 ATM by Art. 13]
STOCKPILING
The storage of unsecured material for future use, excluding
the storage of materials 10 cubic yards or less secured and utilizing
erosion controls to prevent erosion of material.
STORMWATER MANAGEMENT
The use of structural or nonstructural practices that are
designed to control or treat stormwater runoff pollutant loads, discharge
volumes, and/or peak flow discharge rates. Stormwater management includes
the use of low-impact development (LID) management practices.
STORMWATER MANAGEMENT PERMIT (SMP)
A permit issued by the Conservation Commission in its capacity
as the PGA, after review of an application, plans, calculations, and
other supporting documents, which is designed to protect the environment
of the Town from the deleterious effects of uncontrolled and untreated
stormwater runoff.
This chapter is adopted under authority granted by the Home
Rule Amendment of the Massachusetts Constitution and the Home Rule
statutes, and pursuant to the regulations of the federal Clean Water
Act found at 40 CFR 122.34., and as authorized by the residents of
the Town of Georgetown at Town Meeting dated May 2, 2011.
