The following definitions shall be applicable in this
chapter:
AGRICULTURAL LAND USE
Use of land for planting, growing, cultivating and harvesting of
crops for human or livestock consumption and pasturing or yarding of livestock.
CONTROL MEASURE
A practice or combination of practices to control erosion and attendant
pollution.
CONTROL PLAN
A written description of the number, locations, sizes and other pertinent
information of control measures designed to meet the requirements of this
chapter submitted by the applicant for review and approval by the Building
Inspector.
EROSION
The detachment and movement of soil, sediment or rock fragments by
water, wind, ice or gravity.
EXISTING GRADE
The vertical location of the existing ground surface prior to excavation
of filling.
FILL
Any act by which earth, sand, gravel, rock or any other material
is deposited, placed, replaced, pushed, dumped, pulled, transported or moved
by man/woman to a new location and shall include the conditions resulting
therefrom.
GRADING
Altering the elevation of the land surface by stripping, excavating,
filling, stockpiling of soil materials or any combination thereof and shall
include the land from which the material was taken or upon which it was placed.
LAND DEVELOPING ACTIVITY
The construction of buildings, roads, parking lots, paved storage
areas and similar facilities.
LAND DISTURBING ACTIVITY
Any change to the land surface which may result in soil erosion,
sedimentation or increase in water runoff, including but not limited to tilling,
removal of vegetative cover, stockpiling of soil, grading, excavating, livestock
grazing and filling of land.
LAND DISTURBING CONSTRUCTION ACTIVITY
Any man-made change of the land surface including removing vegetation
cover, excavating, filling and grading, but not including agricultural land
uses such as planting, growing, cultivating and harvesting of crops; growing
and tending of gardens; harvesting of trees; and landscaping modifications.
LANDOWNER
Any person holding title to or having any interest in land.
LAND TREATMENT MEASURES
Structural or vegetative practices (including fencing) used to control
erosion, sediment and water runoff.
LAND USER
Any person who uses land collectively or individually as owner, operator,
lessor or renter, or who occupies land by providing work or service that requires
alteration of the land, or any person who has made other arrangements with
a landowner which gives them the right and/or responsibility for use of the
land.
MAJOR LAND DISTURBING ACTIVITIES
Those activities where the land disturbance covers one or more acres,
where a subdivision (as defined by Ch. 236, Wis. Stats.) is created, or where
the Common Council, Plan Commission or Building Inspector determines that
special circumstances due to topography, proximity to watercourses or relation
to sensitive environmental area make the disturbance a major one.
MINOR LAND DISTURBING ACTIVITIES
Those activities where the land disturbance covers less than one
acre and the activities do not otherwise fall within the definition of "major
land disturbing activities."
PARCEL
All continuous lands under the ownership or control of a land occupier
or land user.
PEAK FLOW
The maximum rate of flow of water at a given point in a channel,
watercourse, or conduit resulting from a predetermined storm or flood.
PERSON
Any individual, corporation, partnership, joint venture, agency,
unincorporated association, municipal corporation, county, or state agency
within Wisconsin, the federal government or any combination thereof.
PUBLIC LANDS
All lands owned or controlled by any unit of government.
RUNOFF
Includes, but is not limited to, ice or water flowing over the ground
surface.
SEDIMENT
Solid material, mineral or organic, that is in suspension, is being
transported to, or has been moved from, its site of origin by air, water,
gravity or ice and has come to rest or has been deposited on the earth's surface
at another location.
SEDIMENTATION
The transportation and deposition of sediment that may ultimately
degrade water quality by the presence of suspended solid particles, derived
from soils by erosion or discharged into surface waters from other sources,
or the deposition of waterborne sediments in stream channels, lakes, reservoirs,
or on floodplains, usually resulting from a decrease in the velocity of the
water flow.
SET OF ONE-YEAR DESIGN STORMS
The following rain intensities and rain volumes or corresponding
values specific to the community for the storm durations of 0.5, 1, 2, 3,
6, 12 and 24 hours that occur approximately one per year. The following are
typical characteristics of these one-year storms for most of Wisconsin.

SITE
The entire area included in the legal description of the land on
which the land disturbing or land development activity is proposed in the
permit application.
SOIL LOSS
Soil removed from a given site by land disturbing activities or by
the forces of erosion, and redeposited at another site.
STORM FREQUENCY
The average period of time during which a storm of a given duration
and intensity can be expected to be equaled or exceeded.
STORM SEWER
A closed conduit for conducting collected stormwater.
STORMWATER RUNOFF
The waters derived from rains falling within a tributary drainage
basin, flowing over the ground surface or collected in a water drainage system.
STRUCTURAL MEASURES
Land treatments intended to prevent erosion, sediment or runoff that
include, but are not limited to, gully control structures, grass waterways,
riprap, detention basins or ponds, sediment basins or ponds, flood retention
dams, diversions, and lining channels with rock concrete or other materials.
Contour strip cropping is not considered a structural measure under this chapter.
WATER DRAINAGE SYSTEM
All facilities used for conducting runoff to, through or from a drainage
area to the point of final outlet including, but not limited to, any of the
following: conduits and appurtenant features, canals, channels, ditches, streams,
culverts, reservoirs, detention basins or ponds, storm sewers, streets, and
pumping stations.
WORKING DAY
Monday, Tuesday, Wednesday, Thursday or Friday, excluding, however,
any such day officially observed by the City as a legal holiday. Also referred
to as "business day."
