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 non-point source pollution, and promote stormwater quality
and protection of the environment.
A.
Structural BMPs are devices that are engineered and constructed
to provide temporary storage and treatment of stormwater runoff.
B.
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 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 open space, reducing impervious cover, and using
natural features for stormwater management.
CLEARING
Any activity that removes the vegetative surface cover.
CONSTRUCTION AND WASTE MATERIALS
Excess or discarded building or site materials, including
but not limited to concrete truck washout, chemicals, litter and sanitary
waste at construction sites that may adversely impact water quality.

of an existing use, usually involving construction.
DISCHARGE
A general outflow term including flow from a pipe into a
stream, or from a stream to a body of water.

forces such as wind, water, ice, gravity, or vehicle traffic and the
subsequent detachment and transportation of soil particles.
EROSION AND SEDIMENTATION CONTROL PLAN
A document containing narrative, drawings and details developed
by a qualified professional engineer (PE) 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.
ILLICIT DISCHARGE
Any direct or indirect discharge to the municipal separate
storm sewer system and municipal storm drain system that is not composed
entirely of stormwater, except for projects exempted by this bylaw
or regulations issued thereunder. The term does not include a discharge
in compliance with an NPDES stormwater discharge permit or resulting
from fire-fighting activities.
IMPERVIOUS SURFACE
Any material or structure on or above the ground that prevents
water infiltration to the underlying soils. "Impervious surface" includes
without limitation roads, paved parking lots, sidewalks, stone patios,
decking, and rooftops.
INFILTRATION
The movement of water downward into the soil. Infiltration
is important to replenishing the groundwater.

other vegetation that causes a change in the position or location
of soil, sand, rock, gravel, or similar earth material.
LAND USE CONVERSION ACTIVITY
Any activity which will measurably change the ability of
a ground surface area to absorb water or will change existing surface
drainage patterns.
LOCAL GENERAL PERMIT
Work permitted by right under this chapter, providing that
there is an approved erosion and sediment control plan for the land-disturbing
activity.
MASSACHUSETTS STORMWATER MANAGEMENT POLICY
The policy issued by the Department of Environmental Protection,
and as amended, that coordinates the requirements prescribed by state
regulations promulgated under the authority of the Massachusetts Wetlands
Protection Act, MGL c. 131, § 40, and the Massachusetts
Clean Waters Act, MGL c. 21, §§ 23 through 56.
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 Wayland.
NATURAL VEGETATED STATE
Ground covers of native plants species and other trees, shrubs,
and/or grasses that are not mowed more than twice a year.

Any construction or land disturbance of a parcel of land
that is currently in a natural vegetated state and does not contain
alteration by man-made activities.
NON-POINT SOURCE POLLUTION
Pollution from many diffuse sources caused by rainfall or
snowmelt 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.
