[HISTORY: Adopted by the Village Board of Trustees 10-4-1993 (Title 15, Ch. 2, of the 1993
Code of Ordinances), as amended through 2-17-2015. Subsequent amendments noted where applicable.]
This chapter is adopted pursuant to the guidelines in § 61.354,
Wis. Stats.
A.
Findings. The Village Board finds runoff from construction sites
carries a significant amount of sediment and other pollutants to the
waters of the state and the Village of Spencer.
B.
Purpose. It is the purpose of this chapter to preserve the natural
resources; to protect the quality of the waters of the state and Village;
and to protect and promote the health, safety and welfare of the people,
to the extent practicable by minimizing the amount of sediment and
other pollutants carried by runoff or discharge from construction
sites to lakes, streams and wetlands.
This chapter applies to land disturbing and land developing
activities on land within the boundaries and jurisdiction of the Village
and the public and private lands subject to extraterritorial review
under Ch. 236, Wis. Stats. All state funded or conducted construction
is exempt from this chapter.
NOTE: State funded or conducted construction activities must
meet the requirements contained in the "State Plan for the Control
of Construction Erosion and Stormwater Runoff," which contains similar
requirements as contained in this chapter, as a minimum.
As used in this chapter, the following terms shall have the
meanings indicated:
Use of land for planting, growing, cultivating and harvesting
of crops for human or livestock consumption and pasturing or yarding
of livestock.
Use of land for the retail or wholesale sale of goods or
services.
A control measure used to meet the requirements of § 413-7B.
A practice or combination of practices to control erosion
and attendant pollution.
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.
The detachment and movement of soil, sediment or rock fragments
by water, wind, ice or gravity.
The construction of buildings, roads, parking lots, paved
storage areas and similar facilities.
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.
Any person operating, leasing, renting, or having made other
arrangements with the landowner by which the landowner authorizes
uses of his land.
Any person holding title to or having any interest in land.
The rainfall, snowmelt, or irrigation water flowing over
the ground surface.
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.[1]

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.
All control measures required to comply with this chapter shall
meet the design criteria, standards and specifications for the control
measures based on accepted design criteria, standards and specifications
identified by the Building Inspector.
All sedimentation basins and other control measures necessary
to meet the requirements of this chapter shall be maintained by the
applicant or subsequent landowner during the period of land disturbance
and land development of the site in a satisfactory manner to ensure
adequate performance and to prevent nuisance conditions.
A.
Applicability. This section applies to the following sites of land
development or land disturbing activities:
(2)
Those requiring a certified survey approval or the construction of
houses of commercial, industrial or institutional buildings on lots
of approved certified surveys.
(3)
Those involving grading, removal of protective ground cover or vegetation,
excavation, land filling or other land disturbing activity affecting
a surface area of 4,000 square feet or more.
(4)
Those involving excavation or filling or a combination of excavation
and filling affecting 400 cubic yards or more of dirt, sand or other
excavation or fill material.
(5)
Those involving street, highway, road or bridge construction, enlargement,
relocation or reconstruction.
(6)
Those involving the laying, repairing, replacing or enlarging of
an underground pipe or facility for a distance of 300 feet or more.
NOTE: The above applicability criteria are specifically stated
in 1983 Wisconsin Act 416 for inclusion in this chapter. Utility companies
responsible for energy repair work should enter into a "memorandum
of agreement" with the Building Inspector, clearly stating their responsibilities
if their activities may be included under any of the above applicability
criteria.
B.
Erosion and other pollutant control requirements. The following requirements shall be met on all sites described in Subsection A.
(1)
Site dewatering. Water pumped from the site shall be treated by temporary
sedimentation basins, grit chambers, sand filters, up-slope chambers,
hydrocyclones, swirl concentrators, or other appropriate controls
designed and used to remove particles of 100 microns or greater for
the highest dewatering pumping rate. If the water is demonstrated
to have no particles greater than 100 microns during dewatering operations,
then no control is needed before discharge, except as determined by
the Building Inspector. Water may not be discharged in a manner that
causes erosion of the site or receiving channels.
NOTE: There are several ways to meet this particle-size performance
objective, depending on the pumping rate. As an example, if the pumping
rate is very low (1 gal/min), then an inclined or vertical enlargement
pipe (about eight inches in diameter for 1 gal/min) several feet long
would be an adequate control device to restrict the discharge of 100
micron, and larger, particles. As the pumping rate increases, then
the "device" must be enlarged. At a moderate (100 gal/min) pumping
rate, a vertical section of corrugated steel pipe, or concrete pipe
section, or other small "tank" (about 4 1/2 feet across for a
100 gal/min pumping rate) several feet tall would be adequate. With
these pipe sections or small tanks, inlet baffles would be needed
to minimize turbulence. With very large pumping rates (10,000 gal/min),
sediment basins (about 35 feet in diameter for a pumping rate of 10,000
gal/min) at least three feet in depth with a simple (but adequately
sized) pipe outlet would be needed. More sophisticated control devices
(such as swirl concentrators or hydro-cyclones) could be specially
fabricated that would generally be smaller than the simple sedimentation
devices described above, but they would not be required.
(2)
Waste and material disposal. All waste and unused building materials
(including garbage, debris, cleaning wastes, wastewater, toxic materials,
or hazardous materials) shall be properly disposed and not allowed
to be carried by runoff into a receiving channel or storm sewer system.
(3)
Tracking. Each nonresidential site shall have graveled roads, access
drives and parking areas of sufficient width and length to prevent
sediment from being tracked onto public or private roadways.
(4)
Drain inlet protection. All storm drain inlets shall be protected
with a straw bale, filter fabric, or equivalent barrier meeting accepted
design criteria, standards and specifications.
(5)
Site erosion control. The following criteria apply only to land development
or land disturbing activities that result in runoff leaving the site:
(a)
Channelized runoff from adjacent areas passing through the site shall be diverted around disturbed areas, if practical. Otherwise, the channel shall be protected as described below in Subsection B(5)(c)[3]. Sheetflow runoff from adjacent areas greater than 10,000 square feet in area shall also be diverted around disturbed areas unless shown to have resultant runoff velocities of less than 0.5 feet/second across the disturbed area for the set of one-year design storms. Diverted runoff shall be conveyed in a manner that will not erode the conveyance and receiving channels.
NOTE: Natural Resources Conservation Service guidelines for
allowable velocities in different types of channels should be followed.
(b)
All activities on the site shall be conducted in a logical sequence
to minimize the area of bare soil exposed at any one time.
(c)
Runoff from the entire area disturbed area on the site shall
be controlled by meeting either of the following:
[1]
All disturbed ground left inactive for seven or more days shall
be stabilized by seeding or sodding (only available prior to September
15) or by mulching or covering, or other equivalent control measure.
[2]
For sites with more than 10 acres disturbed at one time, or
if a channel originates in the disturbed area, one or more sedimentation
basins shall be constructed. Each sedimentation basin shall have a
surface area of at least 1% of the area draining to the basin and
at least three feet of depth and constructed in accordance with accepted
design specifications. Sediment shall be removed to maintain a depth
of three feet. The basin shall be designed to trap sediment greater
than 15 microns in size, based on the set of one-year design storms
having durations from 0.5 to 24 hours. The basin discharge rate shall
also be sufficiently low as to not cause erosion along the discharge
channel or the receiving water.
[3]
For sites with less than 10 acres disturbed at one time, filter
fences, straw bales, or equivalent control measures shall be placed
along all sideslope and downslope sides of the site. If a channel
or area of concentrated runoff passes through the site, filter fences
shall be placed along the channel edges to reduce sediment reaching
the channel.
(d)
Any soil or dirt storage piles containing more than 10 cubic
yards of material should not be located with a downslope drainage
length of less than 25 feet to a roadway or drainage channel. If remaining
for more than seven days, they shall be stabilized by mulching, vegetative
cover, tarps or other means. Erosion from piles which will be in existence
for less than seven days shall be controlled by placing straw bales
or filter fence barriers around the pile. In-street utility repair
or construction soil or dirt storage piles located closer than 25
feet of a roadway or drainage channel must be covered with tarps or
suitable alternative control if exposed for more than seven days,
and the storm drain inlets must be protected with straw bales or other
appropriate filtering barriers.
A.
Permit application. No landowner or land user may commence a land
disturbance or land development activity subject to this chapter without
receiving prior approval of a control plan for the site and a permit
from the Building Inspector. At least one landowner or land user controlling
