This chapter may be referred to as the "Town of Marion Stormwater,
Erosion and Sediment Control Law."
In order to protect, maintain and enhance both the natural environment
including groundwater and surface water in conjunction with the safety
and general welfare of the citizens of the Town of Marion, this chapter
has the following objectives:
A. To control stormwater, erosion and sedimentation so as to prevent
it from depositing in streams and other receiving water bodies, including
culverts, drainage systems and public lands;
B. Maintain the integrity of local drainage systems, so as to sustain
their hydrologic functions;
C. Prevent increases in the magnitude and frequency of stormwater runoff
so as to prevent localized flooding and costs associated with flooding;
D. Facilitate the removal of pollutants in stormwater runoff so as to
perpetuate the natural functions of streams, receiving waters and
to protect groundwater supplies;
E. To the extent practical, secure multiple community benefits such
as groundwater protection and replenishment, open space protection
and increased recreational opportunity, through integrated land use
and stormwater management planning.
In accordance with § 10 of the Municipal Home Rule
Law, Article 9 of the Town Law of the State of New York, the Town
has the authority to enact local laws for the purpose of promoting
the health, safety or general welfare of the Town's residents.
The Town may include in any such local law provisions for the appointment
of any municipal officer or employees to effectuate and administer
such local law.
Upon approval of this chapter by the Town, all site preparation
and construction activities requiring approval under this chapter
shall be in conformance with the provisions set forth herein.
Unless specifically defined below, words or phrases shall be
interpreted so as to give them the meaning they have in common usage
and to give this chapter its most effective application. Words used
in the singular shall include the plural and the plural the singular;
words used in the present tense shall include the future tense. The
word "shall" connotes mandatory and not discretionary; the word "may"
is permissive.
ADVERSE IMPACT
Any effect on receiving waters, including their quality,
quantity, surface area, aesthetics or usefulness for human or natural
uses which is or may potentially be harmful or injurious to human
health, welfare, safety or property, or that which unreasonably interferes
with the enjoyment of life or property, including outdoor recreation.
APPLICANT
Any person who executes the necessary forms to procure official
approval of a project or a permit to carry out construction of a project.
CLEAR
Any activity which removes the vegetative ground cover.
DEVELOPMENT
To make a site or area available for use by physical alteration.
Development includes but is not limited to providing access to a site,
clearing of vegetation, grading, earth moving, providing utilities
and other services such as parking facilities, stormwater management
and erosion control systems, and sewage disposal systems, altering
landforms, or construction of a structure on the land.
DRAINAGE AREA
That area contributing runoff to a single point, and/or its
watershed.
EROSION
The removal of soil particles by the action of water, wind,
ice or other geological factors.
EROSION AND SEDIMENT CONTROL PLAN
An erosion and sediment control strategy or plan, to minimize
erosion and prevent off-site sedimentation by containing sediment
on site or by passing sediment-laden runoff through a sediment control
measure, prepared and approved in accordance with the specific requirements
of the Marion Planning Board, the Town Engineer, and this chapter.
FIRST FLUSH
The delivery of a large load of pollutants during the early
part of storms due to rapid runoff of accumulated pollutants. The
"first flush" in these guidelines is defined as the runoff generated
from a one-year twenty-four-hour storm event from land which has been
made more impervious from predevelopment conditions through land grading
and construction/development activities.
FLOODPLAIN
For a given flood event, that area of land temporarily covered
by water which adjoins a watercourse.
IMPERVIOUS AREA
Impermeable surfaces, such as pavement or rooftops, which
prevent the percolation of water into the soil.
PEAK FLOW
The maximum rate of flow of water at a given point and time
resulting from a storm event.
RETENTION
A practice designed to store stormwater runoff by collection
as a permanent pool of water without release except by means of evaporation,
infiltration, or attenuated release when runoff volume exceeds the
permanent storage capacity of the permanent pool.
RIPRAP
A combination of large stone, cobbles and boulders used to
line channels, stabilize stream banks and reduce runoff velocities.
STREAM CORRIDOR
The landscape features on both sides of a stream, including
soils, slope, and vegetation, whose alteration can directly impact
the stream's physical characteristics and biological properties.
WATERSHED
The total drainage area contributing runoff to a single point.
