DEVELOPMENT
Residential, commercial, industrial, institutional, or other
land uses and associated roads.
DIVISION OF LAND
The creation from one or more parcels or building sites of
additional parcels or building sites where such creation occurs at
one time or through the successive partition within a five-year period.
EROSION
The process by which the land's surface is worn away
by the action of wind, water, ice or gravity.
EROSION AND SEDIMENT CONTROL PLAN
A comprehensive plan developed to address pollution caused
by erosion and sedimentation of soil particles or rock fragments during
construction.
EXTRATERRITORIAL
The unincorporated area within three miles of the corporate
limits of a first-, second-, or third-class city, or within 1.5 miles
of a fourth-class city or village.
FINAL STABILIZATION
The point in time when all land disturbing construction activities
at the construction site have been completed and that a uniform perennial
vegetative cover has been established, with a density of at least
70% of the cover, for the unpaved areas and areas not covered by permanent
structures, or that employ equivalent permanent stabilization measures.
GOVERNING BODY
Town Board of Supervisors, County Board of Supervisors, City
Council, Village Board of Trustees or Village Council.
LAND DISTURBING CONSTRUCTION ACTIVITY
Any man-made alteration of the land surface resulting in
a change in the topography or existing vegetative or nonvegetative
soil cover that may result in runoff and lead to an increase in soil
erosion and movement of pollutants into the municipal separate storm
sewer or waters of the state. Land disturbing construction activity
includes clearing and grubbing, demolition, excavating, pit trench
dewatering, filling and grading activities, and soil stockpiling.
Also referred to as "disturbance."
MAXIMUM EXTENT PRACTICABLE
The highest level of performance that is achievable but is
not equivalent to a performance standard identified within this chapter.
"Maximum extent practicable" applies when the permit applicant demonstrates
to the administering authority's satisfaction that a performance
standard is not achievable and that a lower level of performance is
appropriate. In making the assertion that a performance standard is
not achievable and that a level of performance different from the
performance standard is the maximum extent practicable, the permit
applicant shall take into account the best available technology, cost
effectiveness, geographic features, and other competing interests
such as protection of public safety and welfare, protection of endangered
and threatened resources, and preservation of historic properties.
Also referred to as "MEP."
MSE4 DISTRIBUTION
A specific precipitation distribution developed by the USDA,
NRCS, using precipitation data from Atlas 14.
OFF SITE
Located outside the property boundary described in the permit
application.
ON SITE
Located within the property boundary described in the permit
application.
PERFORMANCE STANDARD
A narrative or measurable number specifying the minimum acceptable
outcome for a facility or practice.
PERMIT
A written authorization by the administering authority to
the applicant, granting permission to conduct land disturbing construction
activity or to discharge post-construction runoff to waters of the
state.
PERMIT ADMINISTRATION FEE
A sum of money paid to the administering authority by the
permit applicant for the purpose of recovering the expenses incurred
by the authority in administering the permit.

as measured horizontally from the top of the channel or delineated
wetland boundary to the closest impervious surface. For the purposes
of this chapter, a protective area does not include any area of land
adjacent to any stream enclosed within a pipe or culvert, such that
runoff cannot enter the enclosure at this location.
RESPONSIBLE PARTY
Any entity holding fee title to a property or performing

and operation and maintenance specifications for a BMP, material,
device or method.
