meanings indicated:

effective in controlling runoff, erosion and/or sedimentation.
BORROW
Fill material which is required for on-site construction
which is obtained from other locations.
BUFFER AREA
The strip of land adjacent to a water body, wetland or watercourse.
CERTIFICATION
A signed, written approval by the Planning and Zoning Commission
that the soil erosion and sediment control plan and notes comply with
the applicable requirements of these regulations.
CLEARING and GRUBBING
The cutting and removal of trees, shrubs, bushes and turf,
including stumps and roots.
COMMISSION

provides for the temporary storage of stormwater runoff.
DEVELOPER
Any person, firm, corporation, sole proprietor, partnership,
state agency or political subdivision thereof engaged in a land disturbance.
DEVELOPMENT
Any construction or grading activities related to residential,
industrial or commercial activities.
DISTURBED AREA
Any area where the ground cover is destroyed or removed leaving
the land subject to accelerated erosion.
ENERGY DISSIPATER
A structure or a shaped channel section with mechanical armoring
placed at the discharge point of pipes or conduits to receive and
break down the energy from high-velocity flow.
EROSION
The detachment and movement of soil, earth, sand and/or rock
by the action of water, wind, ice, gravity or any combination thereof.
EROSION AND SEDIMENT CONTROL PLAN
A plan which includes a set of best management practices
or equivalent measures designed to control surface runoff and erosion
and to retain sediment on a particular site during the period in which
pre-construction and construction-related land disturbances, fills,
and soil storage occur and before final improvements are completed.
EXCAVATION
The mechanical removal of earth material.
FILL
The deposit of soil or earth materials placed by artificial
means.
GRADING
The altering of the existing earth's surface elevations
by any method.
GROUND COVER
Any natural vegetative growth or other material that renders
the soil surfaces stable against accelerated erosion.
INSPECTION
The periodic review of sediment and erosion control measures
as approved or directed by the Planning and Zoning Commission.
OUTFALL
The point of discharge to any water body, wetland or watercourse
from a public or private stormwater drainage system.
RETENTION POND
A temporary or permanent natural or man-made structure that
provides for the storage of stormwater runoff by means of a pool of
water.
RUNOFF
Rainfall, snowmelt or irrigation water which flows over the
earth's surface.
SEDIMENT
Soil or other sacrificial materials transported by surface
water, ice, wind, gravity or combination thereof.
SEDIMENTATION
The process or action of deposition of sediment that is determined
to have been caused by erosion.
SITE
The entire area of land on which the land disturbance activity
is proposed.
SITE PLAN
A plan or set of plans showing the details of any land disturbance
activity of a site, including but not limited to the construction
of structures, open and enclosed drainage facilities, stormwater management
facilities, parking lots, driveways, curbs, pavements, sidewalks,
bike paths, recreational facilities, and landscaping.
SLOPE
The incline of a ground surface expressed as a ratio of horizontal
distance to vertical distance.
STRIPPING
Any activity which removes or significantly disturbs the
vegetative surface cover, including clearing, grubbing of stumps and
root mat and topsoil removal.
TEN-YEAR STORM
The surface runoff resulting from a rainfall of an intensity
expected to be equaled or exceeded, on the average, once in 10 years,
and of a duration which will produce the maximum peak rate of runoff
from the watershed of interest under average antecedent wetness conditions.
TWENTY-YEAR STORM
The surface runoff resulting from a rainfall of an intensity
expected to be equaled or exceeded, on the average, once in 25 years,
and of a duration which will produce the maximum peak rate of runoff
from the watershed of interest under average antecedent wetness conditions.
VELOCITY
The average speed of flow through the cross section of the
main channel at the peak flow of the storm of interest.
WATERCOURSE
Any natural or improved stream, river, creek, ditch, channel,
canal, gully, or swale in which flow is either continuous or intermittent.
WATERSHED
A region draining to a specific location, river, river system,
wetland, or body of water.
WETLAND
Any area as defined in the Town of Plainville Inland Wetland
and Watercourse Regulations or revisions thereof.
A soil erosion and sedimentation control plan shall be submitted
with any permit application for development or site work when the
disturbed area of such development or activity is cumulatively more
than 5,000 square feet or within 100 feet of any water body, watercourse
and/or wetland.
This chapter shall not apply to the following:
A. Land disturbance activities over which the State of Connecticut has
exclusive regulatory jurisdiction.
B. Construction activities essential to protect human life during a
declared emergency.
