[HISTORY: Adopted by the City Council of the City of Edgerton
as indicated in article histories. Amendments noted where applicable.]
[Adopted 3-1-1993 by Ord.
No. 2-93 (Ch. 30 of the 1993 Municipal Code); amended
in its entirety at time of adoption of Code (see Ch. 1, General Provisions,
Art. II)]
This article shall be known as, referred to, and may be cited
as the "Stormwater Management and Erosion Control Code."
This article is adopted under the authority granted by Wis.
Stats., § 62.234.
A.
Findings. The City Council for the City of Edgerton finds that construction
site erosion and uncontrolled stormwater runoff from land development
activities adversely effect the water resources and the health, safety,
property, and general welfare of the community, and diminish the public
enjoyment and use of natural resources. Soil erosion and stormwater
runoff specifically can:
(1)
Carry sediment, nutrients, pathogens, organic matter, heavy metals,
toxins and other pollutants to regional lakes, streams, creeks, and
wetlands;
(2)
Diminish the capacity of water resources to support recreational
uses and a natural diversity of plant and animal life;
(3)
Clog the City's existing stormwater drainage system, increasing
maintenance problems and costs;
(4)
Cause bank and channel erosion;
(5)
Increase downstream flooding;
(6)
Reduce groundwater recharge, thereby potentially diminishing stream
base flows and lowering water levels in regional lakes, ponds, and
wetlands;
(7)
Increase the risk of property damage and personal injury; and
(8)
Cause damage to agricultural fields and crops.
B.
Declaration of policy. The City finds and declares that effective
sediment and stormwater management depends on proper planning and
design, and the timely installation of conservation and management
practices and their continuing maintenance.
A.
Purpose. The purpose of this article is set forth the minimum requirements
for construction site erosion and stormwater management to diminish
threats to public health and safety, public and private property,
and the natural resources of the City.
B.
Intent. This article is intended to regulate construction site erosion
and stormwater runoff and to accomplish the following objectives:
(1)
Promote stormwater management within the areas subject to this article;
(2)
Minimize the effects of sedimentation, water pollution from nutrients,
heavy metals, chemical and petroleum products and other contaminants,
and flooding;
(3)
Promote infiltration and groundwater recharge;
(4)
Protect functional values of natural watercourses and wetlands;
(5)
Achieve an 80% reduction in average annual sediment loads to the
surface waters in and near the City and outlying waters compared to
no controls for all new land development, a 40% reduction in average
annual sediment loads compared to no controls for all redevelopment
and street reconstruction, and a 20% reduction in average annual sediment
loads compared to no controls for existing developments;
(6)
Ensure no increase in the rate of surface water drainage from sites
during or after construction;
(7)
Protect public and private property from damage resulting from runoff
or erosion; and
(8)
Reduce flood damage to property from large storm events.
Unless exempt from § 439-10, this article applies to the use of all lands within the corporate limits of the City.
A.
Effect. This article is not intended to repeal, abrogate, annul,
impair, or interfere with any existing easements, covenants, deed
restrictions, agreements, rules, regulations, ordinances or permits
previously adopted or issued under City ordinance or state law. However,
wherever this article imposes greater restrictions, the provisions
of this article shall govern.
B.
Interpretation. In their interpretation and application, the provisions
of this article shall be held to be the minimum requirements, shall
be liberally construed in favor of the City, and shall not be deemed
a limitation on or repeal of any other power granted by state law.

familiar with the proposed activity. This meeting is intended to assist
a potential applicant in preparing general site plans and other submittals
necessary to obtain a required permit under this article. A preapplication
conference does not guarantee that an erosion or stormwater control
plan will be approved or that a permit will be issued. Erosion and
stormwater control plans and permit applications must meet all applicable
standards and criteria for approval.
A.
COMBINATION PERMIT
Definitions. Whenever used in this section, the term:
A single permit issued for any land development activity requiring both an erosion control permit and a stormwater control permit, provided the requirements and standards for each such permit as specified under this article are met. Such permit shall be designated as an erosion and stormwater control permit. When applying for a combination permit, the applicant shall file a single plan combining and meeting all of the requirements and standards specified under Subsection C(3) and (4).
B.
Permit as a condition precedent. Unless expressly exempted by this article, no person may undertake or commence any activity i) meeting the criteria described in § 439-8 or 439-9 or ii) deemed subject to the requirements of this article under § 439-10 without first obtaining from the City under this section the permit specifically required for such activity. Such required permit may be either an erosion control permit, a stormwater control permit or, if appropriate, a combination permit.
C.
Application. The following must be provided to obtain an erosion
control permit, a stormwater control permit or, if appropriate, a
combination permit:
(1)
A completed application for the permit sought. The application must
be signed by the landowner or include a notarized statement signed
by the landowner authorizing the applicant to act as the landowner's
agent and to submit the application on the landowner's behalf.
Such notarized statement shall also clearly state that the landowner
agrees to be bound by all of the requirements of this article and
the terms of any permit issued to the agent. By signing the application,
the landowner and, whenever appropriate, the landowner's agent
also expressly grant permission to any City administrative authority
to enter the property at any reasonable time for the purpose of gathering
any information or data needed to assist the City in evaluating the
application and its supporting documentation.
(4)
For either a stormwater control permit or a combination permit, a stormwater management plan meeting all of the standards of § 439-14 and, if appropriate, a draft maintenance agreement as described in § 439-14A(8).

completion of the project. If the City intends to accept dedication
of the improvements after completion, the filing of such a security
shall be mandatory in accordance with the development agreement.
(8)
Copies of permits or permit applications or approvals required by
any other governmental entity.
D.
Application review process.
(1)
The City administrative authority shall verify that the permit application, including the supporting documentation as required by Subsection C, is complete and that proposed plan complies with the standards identified in either § 439-13 or 439-14, or both. If the City administrative authority determines after such review that the proposed plan is deficient in any manner or that additional information is needed to evaluate the plan, the City administrative authority shall notify the applicant of such deficiency or of the need for additional information. Within 20 days after the date of such notification, the applicant shall correct the identified deficiencies or furnish the requested information, or both if appropriate. If the applicant fails to timely correct any identified deficiency or submit the requested information, the application shall be deemed denied and no further action will taken on it. The applicant may then either submit a new application and plan for approval or appeal the determination of the City administrative authority as provided under § 439-16.
(2)
After the application and plan review of the City administrative
authority has been completed and, if appropriate, all identified deficiencies
have been corrected and all additionally requested information has
been submitted, the City administrative authority may approve or reject
the permit request as submitted. The City administrative authority
may also approve the permit request subject to certain enumerated
conditions, including the correction of any identified deficiencies
in the filed plan. The Zoning Administrator shall then notify the
applicant of the action taken by the City administrative authority.
If a permit is approved conditionally or rejected, the Zoning Administrator
shall advise the applicant of the conditions of approval, including
the required correction of identified deficiencies in the plan, or
the reasons for rejection. If the applicant thereafter corrects all
of the identified deficiencies in the plan to the satisfaction of
the City administrative authority, the plan shall then be deemed approved,
subject to any remaining nondeficiency conditions, if any. Staff engaged
in this review and approval process shall be certified where appropriate
by the Wisconsin Department of Safety and Professional Services for
this purpose.

plan as originally approved or as subsequently modified, or has violated
any of the other terms of the permit imposed as a condition of its
approval.
F.
Inspections, security, acceptance and maintenance.
(1)
Entry permitted. A permit issued under this section shall constitute
permission by the permittee and landowner for any City administrative
authority to enter the property and inspect any phase of the permitted
activity, including any construction or installation work, to confirm
its compliance with the approved plan and the requirements of this
article.
(2)
Erosion control and stormwater management inspections. The City administrative
authority shall perform inspections during the construction or installation
phase of any permitted activity to determine the permittee's
substantial compliance with the approved plan and the requirements
of this article.
(3)
Final inspection: stormwater management. Within 10 days after the
installation of all of the stormwater management measures specified

permittee shall submit a certification that the constructed stormwater
management practices and conveyance systems substantially comply with
the specifications included in the approved plan. At a minimum, the
certification shall include a set of record drawings comparing the
approved stormwater management measures with those constructed. The
permittee shall submit any other information as required by the Zoning
Administrator or the City Engineer within 10 days after such request.
A City administrative authority shall then inspect the property to
verify compliance with the plan within 10 days after such notification
or within 10 days after all additionally requested information has
been submitted.

(a)
Unless the City provides otherwise, the City shall accept dedication
of all stormwater management measures and conveyance facilities and
systems after fully constructed, inspected, and approved. The City's
acceptance of such improvements, however, is further conditioned on
the permittee filing lien waivers and appropriate affidavits as evidence
that no claims, actions, or demands for damages arising out of or
in any way related to the installation of the stormwater management
measures and conveyance systems exist and that no monies are owed
to any contractor, surveyor, mechanic, subcontractor, materialman,
or laborer in connection with the installation.
(b)
The City may, at its option, require the landowner to retain
ownership of all stormwater management measures and conveyance facilities
and systems and to maintain them after fully constructed, inspected,
and approved. Such improvements, however, shall be subject to periodic
City inspections and, as necessary, City orders for repairs.
(6)
Security.
(a)
Partial release. Upon completion and approval of any improvement,
the City may release a portion of any furnished security if:
[1]
A written application for a partial release is filed with the
City Clerk; and
[2]
The remaining security will be sufficient to cover any potential
corrective work required during the guaranty as determined by the
City Engineer. Under no circumstances shall more than 90% of the furnished
security be released before the expiration of the guaranty period.
(b)
Guaranty period. The security furnished by the permittee, whether
subject to a partial release or not, shall be retained by the City
for a period of one year following the City's acceptance of the
required improvements to guarantee them against defects in workmanship
and materials. If any defect appears during the guaranty period, the
permittee shall, at his or her expense, install replacements or perform
acceptable repairs. If the permittee fails to do so, the City may
do so and deduct the cost of such work from the security on deposit.
Unless defects have appeared and have not been repaired, the City
shall release the security to the permittee upon expiration of the
one-year-guaranty-period.
G.
Permit transfers.
(1)
Definition. For purposes of this Subsection G, the term "landowner" includes both the current owner of property subject to a permit issued under this section and the current permittee if the permit was issued to an agent of the property owner, unless the context or subject matter clearly indicates otherwise.
(2)
Notification of plan and transfer. If a landowner intends to transfer
ownership, possession or control of property subject to an approved,
yet uncompleted plan, the landowner shall provide a copy of the plan
to the intended successor in interest, inform the intended successor
in interest in writing of the current status of compliance with the
plan, and notify the City administrative authority in writing of the
intended transfer. Until such intended transfer is effectuated, the
landowner shall continue to be responsible for controlling soil erosion
and runoff and complying with the requirements of the approved plan
and the standards provided in this article.
(3)
Method of transfer.
(a)
If a landowner transfers ownership, possession, or control of
property subject to an approved, yet uncompleted plan, the outstanding
permit shall be deemed null and void, all land development activity
shall cease, and the property shall be restored to its original, pre-land-development
condition subject to the requirements of this article, including the
controlling of soil erosion and runoff, unless any of the following
conditions is met prior to the actual date of transfer:
[2]
Subject to Subsection G(2), the City administrative authority agrees to name the transferee as an additional permittee on the outstanding permit and allows the transferee to complete that portion of the approved plan regulating soil erosion and runoff on the transferee's property. As a condition of naming the transferee on the outstanding permit, the City administrative authority may require that the transferee or the landowner furnish an irrevocable letter of credit or certified check in an amount equal to 110% of the estimated cost to complete the work proposed in the approved plan as determined by the City administrative authority, if the landowner was not required to furnish any security at the time the permit was originally issued, or if the previously furnished security by its terms is for any reason rendered void by the transfer. The letter of credit shall be in a form approved by the City and shall name the City as the beneficiary. If an approved plan is not completed as proposed, the City may use the letter of credit or certified check provided by the transferee or landowner to complete the remaining work to achieve plan compliance.
(b)
Even if a transferee is named as additional permittee under Subsection C(1), the City shall continue to deem the landowner as being equally responsible for controlling soil erosion and runoff and complying with the requirements of the approved plan and the standards provided in this article until the plan work is completed on the transferee's property.
H.
Plan or permit amendments. No substantive modification to an approved
plan may be made unless such modification is first approved by City
administrative authority. The City administrative authority shall
determine if a modification is substantive.
A.
Plan materials. Erosion control plans may include the consideration of the cooperative efforts of adjoining landowners to control the transport of sediment, and except as specifically exempted in Subsection B, shall include at a minimum the following information unless waived by the City administrative authority:

of the site.
B.
Simplified plan checklist.
(1)
Applicants may submit erosion control proposals using simplified
checklists of standard erosion control practices on a standard form
approved by the City, wherever all of the following conditions exist:
(2)
Each submitted simplified plan checklist shall be reviewed by the
City administrative authority for completeness and accuracy.
C.
Erosion control performance standards.
(1)
Generally. The proposed design, suggested location, and phased implementation of the erosion control measures specified in a plan should be designed, engineered and ultimately implemented to achieve those results as provided under Subsection C(2). The City administrative authority shall evaluate the plan measures to determine that they follow currently accepted design criteria and the technical standards specified under § 439-15 and that they will achieve the required results under Subsection C(2).
(2)
Standards. The erosion control plan measures shall at a minimum achieve
the following results:
(a)
Prevent gully and bank erosion;
(b)
Limit total off-site permissible annual aggregate soil loss
for exposed areas resulting from sheet and rill erosion to an annual,
cumulative soil loss rate not to exceed 7.5 tons per acre annually;
and
(c)
Discharges from new construction sites must have a stable outlet capable of carrying designed flow as required in § 439-14B(2)(c), at a nonerosive velocity. Outlet design must consider flow capacity and flow duration. This requirement applies to both the site outlet and the ultimate outlet to stormwater conveyance of water body.
(3)
A plan's compliance with the requirements specified under Subsection C(2) shall be determined by using the U.S. Natural Resources Conservation Service Technical Guide or another commonly accepted soil erosion methodology approved by the Dane or Rock County Conservationist that considers season of year, site characteristics, soil erodibility, and slope.
(4)
For a plan to be approved, its prescribed erosion control measures
need not have to attempt to control soil transportation within the
boundaries of the applicant's site.
(5)
Site dewatering. Water pumped from the site shall be treated by control
measures specified in the Wisconsin Construction Site Best Management
Practice Handbook. 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 City. Water
may not be discharged in a manner that causes erosion of the site,
adjacent land or receiving channels.
(6)
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 of and not allowed
to be carried by runoff into a receiving channel or storm sewer system.
(7)
Tracking. Each 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. Any sediment reaching
a public or private road shall be removed by street cleaning (not
flushing) before the end or each workday.
(8)
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.
(9)
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 C(9)(c)[3] below. 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 per second across the disturbed area for the two year twenty-four-hour storm. Diverted runoff shall be conveyed in a manner that will not erode the conveyance and receiving channels. For allowable velocities in different types of channels, Natural Resource Conversation Service guidelines shall 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 disturbed area on the site shall be controlled by meeting either Subsection C(9)(c)[1] and [2] or [1] and [3] below.
[1]
Where activities will result in disturbed ground being left
inactive for 10 or more days, positive controls for keeping all erosion
on site, including such measures as placement of silt fences, hay
bales, detention basins, phased construction or stabilization of the
disturbed ground with temporary or permanent seeding; temporary or
permanent seeding and mulching; sodding or covering with tarps shall
be employed to the satisfaction of the City for the City. Seeding
without mulch may be allowed if the seeding is started and completed
between May 1 and September 15. If temporary seeding is used, a permanent
cover shall also be required as part of the final site stabilization.
Seeding or sodding shall be conducted as specified in the Department
of Natural Resources Wisconsin Construction Site Best Management Practice
Handbook or by the City. Variances from the requirements of this subsection
may be granted by the City upon application, but only if the applicant's
failure to comply is due to extended periods of rain or other construction
delays beyond the control of the responsible party.
[2]
For sites with 10 or more acres disturbed at one time or if
a channel originates in the disturbed area, one or more sedimentation
basins shall be constructed in addition to other erosion control measures.
Each sedimentation basin shall be designed and constructed as specified
in the Department of Natural Resources Wisconsin Construction Site
Best Management Practice Handbook.
[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 side slope and down slope 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)
Runoff from sites on slopes of 12% or more may require additional or different controls than listed in Subsection C(9)(c) above. Control measures for such slopes require approval of the City.
(e)
Any soil or dirt storage piles containing more than 10 cubic
yards of material should not be located with a down slope drainage
length of less than 25 feet to a roadway or drainage channel. Straw
bales or filter fence barriers shall be placed immediately on the
down slope side of the piles. If remaining for more than 30 days,
they shall be stabilized by mulching, vegetative cover, tarps or other
means. Where soil or dirt storage piles resulting from in-street utility
repairs are located closer than 25 feet to a roadway or drainage channel,
adequate control measures shall be taken to prevent erodible materials
from entering the adjacent ditch or storm sewer system. Storm drain
inlets must be protected with straw bales or other appropriate filtering
barriers. If any soil or dirt storage pile described in this subsection
is in existence for more than six months, the filter fabric or straw
bales shall be replaced upon orders of the City.
A.

B.
Stormwater management performance standards.
(1)
Generally. The proposed design, suggested location, and phased implementation of the stormwater management measures specified in a plan should be designed, engineered and ultimately implemented to achieve the results as provided under Subsection B(2). The City administrative authority shall evaluate the plan measures to determine that they follow currently accepted design criteria and the technical standards specified under § 439-15 and that they will achieve the required results under Subsection B(2).
(2)
Standards.
(a)
Sediment control.
[1]
For new development, the applicant shall design the stormwater
management measures to retain soil particles greater than five microns
on the site (80% reduction) resulting from a one-year, twenty-four-hour
storm event (2.5 inches over twenty-four-hour duration), according
to approved procedures, and assuming no sediment resuspension.
[2]
For redevelopment resulting in exposed surface parking lots
and associated traffic areas, the applicant shall design the stormwater
management measures to retain soil particles greater than 20 microns
on the entire site (40% reduction) resulting from a one-year, twenty-four-hour
storm event, according to approved procedures, and assuming no sediment
resuspension. Under no circumstances shall the-existing sediment control
level or trapping efficiency of the site be reduced as a result of
the redevelopment.
(b)
Outlets. Discharges from land development activities must have a stable outlet capable of carrying the designed flow as required in Subsection B(2)(d), at a nonerosive velocity. Outlet design must consider flow capacity and flow duration. This requirement applies to both the site outlet and the ultimate outlet to a stormwater conveyance or water body.
(c)
Runoff rate control; hydrologic calculation. All runoff calculations
shall be according to the methodology described in the Natural Resources
Conservation Service's Technical Release 55, "Urban Hydrology
for Small Watersheds" (commonly known as TP-55), or other methodology
approved by the City administrative authority. For agricultural land
subject to this section, the maximum runoff curve number (RCN) used
in such calculations shall be 51 for HSG A; 68 for HSG B; 79 for HSG
C; and 84 for HSG D. The TR-55-specified curve numbers for other land
uses shall be used. Heavily disturbed sites will be lowered one permeability
class for hydrologic calculations. Lightly disturbed area require
no modification. Where practices have been implemented to restore
soil structure to pre-development conditions, not permeability class
modification is required.
(d)
Runoff rate control; design standards. Except for redevelopment
projects, all stormwater facilities shall be designed, installed and
maintained to effectively accomplished the following:
[1]
Maintain predevelopment peak runoff rates for two-year, twenty-four-hour
storm event (2.9 inches over twenty-four-hour duration).
[2]
Maintain predevelopment peak runoff rates for the ten-year,
twenty-four-hour storm event (4.2 inches over twenty-four-hour duration).
[3]
Detain the 100-year, twenty-four-hour storm event (6.0 inches
over twenty-four-hour duration).
(e)
Infiltration.
[1]
Residential development. For residential developments, design
practices to infiltrate sufficient runoff volume so that post-development
infiltration volume shall be at least 90% of the predevelopment infiltration
volume, based upon average annual rainfall. If when designing appropriate
infiltration systems no more than 1% of the site is required to be
used as effective infiltration area, the applicant may alternately
design infiltration systems and pervious surfaces to meet or exceed
the estimated average annual recharge rate (7.6 inches per year).
If this alternative design approach is taken, at least 1% of the site
must be used for infiltration.
[2]
Nonresidential development. For nonresidential development including
commercial industrial and institutional development design practices
to infiltrate sufficient runoff volume so that post-development infiltration
volume shall be at least 60% of the predevelopment infiltration volume,
based on average annual rainfall. When designing appropriate infiltration
systems, no more than 2% of the site is required to be used as effective
infiltration area, the applicant may alternately design infiltration
systems and pervious surfaces to meet or exceed the estimated average
annual recharge rate (7.6 inches per year). If this alternative design
approach is taken, at least 2% of the site must be used for infiltration.
[3]
Pretreatment. Before infiltrating runoff, pretreatment shall
be required for parking lot runoff and for runoff from new road construction
in commercial, industrial and institutional areas that will enter
an infiltration system. The pretreatment shall be designed to protect
the infiltration system from clogging prior to scheduled maintenance
and to protect groundwater quality.
[4]
Prohibitions. Notwithstanding Subsection B(2)(e)[1] through [3], infiltration systems may not be installed in any of the following areas:
[a]
Areas associated with Tier 1 industrial facilities
identified in § NR 216.21 (2)(a), Wis. Admin. Code. including
storage, loading, rooftop and parking.
[b]
Storage and loading areas of Tier 2 industrial
facilities identified in § NR 216.21(2)(b), Wis. Admin.
Code.
[c]
Fueling and vehicle maintenance areas.
[d]
Areas within 1,000 feet UP gradient or within 100
feet down gradient of karst features.
[e]
Areas with less than three feet separation distance
from bottom of the infiltration system to the elevation of seasonal
high groundwater or the top of bedrock, except that this provision
does not prohibit infiltration of roof runoff.
[f]
Areas with runoff from industrial, commercial and
institutional parking lots and roads and residential arterial roads
with less than five feet separation distance from the bottom of the
infiltration system to the elevation of seasonal high groundwater
or the top of bedrock.
[g]
Areas within 400 feet of a community water system
well as specified in § NR 811.12(5). Wis. Admin. Code, for
runoff infiltrated from commercial, industrial and institutional land
uses or regional devices for residential development.
[h]
Areas where contaminants of concern, as defined
in § NR 720.03(2), Wis. Admin. Code, are present in the
soil through which infiltration will occur.
[i]
Any area where the soil does not exhibit one of
the following characteristics between the bottom of the infiltration
system and the seasonal high groundwater and top of bedrock: at least
a five foot soil layer with 10% fines or greater. This provision does
not apply where the soil medium within the infiltration system provides
an equivalent level of protection and does not prohibit infiltration
of roof runoff.
[5]
Alternate use of runoff. Where alternate uses of runoff are
employed, such as for toilet flushing, laundry or irrigation, such
alternate use shall be given equal credit toward the infiltration
volume required by this section.
[6]
Minimizing groundwater pollution. According to Ch. NR 151, Wis.
Admin. Code, infiltration systems designed in accordance with this
section shall, to the extent technically and economically feasible,
minimize the level of pollutants infiltrating to groundwater and shall
maintain compliance with the preventive action limit at a point of
standards application in accordance with Ch. NR 140, Wis. Admin. Code.
However, if site specific information indicates that compliance with
the preventive action limit is not achievable, the infiltration system
may not be installed or shall be modified to prevent infiltration
to the maximum extent practicable.
(f)
Projects regulated by Chapters 405, Floodplain Regulation, and 435, Shoreland-Wetland Zoning, must comply with the following regulations.
[1]
In this subsection, "protective area" means an area of land
that commences at the top of the channel of lakes, streams and rivers,
or at the delineated boundary of wetlands, and that is the greatest
of the following widths, as measured horizontally from the top of
the channel or delineated wetland boundary to the closest impervious
surface. However, in this subsection, "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.
[a]
For outstanding resource waters and exceptional
resource waters, and for wetlands in areas of special natural resource
interest as specified in § NR 103.04, 75 feet.
[b]
For perennial and intermittent streams identified
on a United States Geological Survey 7.5-minute series topographic
map, or a county soil survey map, whichever is more current, 50 feet.
[c]
For lakes, 50 feet.
[d]
For highly susceptible wetlands, 50 feet. Highly
susceptible wetlands include the following types: fens, sedge meadows,
bogs, low prairies, conifer swamps, shrub swamps, other forested wetlands,
fresh wet meadows, shallow marshes, deep marshes and seasonally flooded
basins. Wetland boundary delineation shall be made in accordance with
§ NR 103.08(1m), Wis. Adm. Code. This subsection does not
apply to wetlands that have been completely filled in accordance with
all applicable state and federal regulations. The protective area
for wetlands that have been partially filled in accordance with all
applicable state and federal regulations shall be measured from the
wetland boundary delineation after fill has been placed.
[e]
For less susceptible wetlands, 10% of the average
wetland width, but no less than 10 feet nor more than 30 feet. Less
susceptible wetlands include degraded wetlands dominated by invasive
species such as reed canary grass.
[f]
In Subsection B(2)(f)[1][a]. [d] and [e], determinations of the extent of the protective area adjacent to wetlands shall be made on the basis of the sensitivity and runoff susceptibility of the wetland in accordance with the standards and criteria in § NR 103.03, Wis. Adm. Code.
[g]
For concentrated flow channels with drainage areas
greater than 130 acres, 10 feet.
[2]
This subsection applies to post-construction sites located within a protective area, except those areas exempted pursuant to Subsection B(2)(f)[4].
[3]
The following requirements shall be met:
[a]
Impervious surfaces shall be kept out of the protective
area to the maximum extent practicable. The stormwater management
plan shall contain a written site specific explanation for any parts
of the protective area that are disturbed during construction.
[b]
Where land disturbing construction activity occurs
within a protective area, and where no impervious surface is present,
adequate sod or self-sustaining vegetative cover of 70% or greater
shall be established and maintained. The adequate sod or self-sustaining
vegetative cover shall be sufficient to provide for bank stability,
maintenance of fish habitat and filtering of pollutants from upslope
overland flow areas under sheet flow conditions. Nonvegetative materials,
such as rock riprap, may be employed on the bank as necessary to prevent
erosion such as on steep slopes or where high velocity flows occur.
(NOTE: it is recommended that seeding of nonaggressive vegetative
cover be used in the protective areas. Vegetation that is flood and
drought tolerant and can provide long-term bank stability because
of an extensive root system is preferable. Vegetative cover may be
measured using the line transect method described in the University
of Wisconsin Extension publication No. A3533, titled "Estimating Residue
Using the Line Transect Method.")
[c]
Best management practices such as filter strips,
swales or wet detention basins that are designed to control pollutants
from nonpoint sources may be located in the protective area. (NOTE:
other regulations, such as Ch. 30, Wis. Stats., and Chs., NR 103,
115, 116 and 117, Wis. Adm. Code, and their associated review and
approval process may apply in the protective area.)
[4]
Exemptions. This subsection does not apply to:
[a]
Redevelopment post-construction sites.
[b]
In-fill development areas less than five acres.
[c]
Structures that cross or access surface waters
such as boat landing, bridges and culverts.
[d]
Structures constructed in accordance with § 59.692(1v),
Wis. Stats.
[e]
Post-construction sites from which runoff does not enter the surface water, except to the extent that vegetative ground cover is necessary to maintain bank stability. (NOTE: a vegetated protective area to filter runoff pollutants from post-construction sites described in Subsection B(2)(f)[4][e] is not necessary since runoff is not entering the surface water at that location. Other practices necessary to meet the requirements of this section, such as a swale or basin, will need to be designed and implemented to reduce runoff pollutants prior to runoff entering a surface water of the state.)
(g)
Oil and grease control. For all stormwater plans for commercial
or industrial developments and all other uses where the potential
for pollution by oil or grease, or both, exists, the first 0.5 inches
of runoff will be treated using the best oil and grease removal technology
available. This requirement may be waived by the plan reviewer only
when the applicant can demonstrate that installation of such practices
is not necessary and only applies to property in Dane County.
C.
Stormwater management goals. The following standards shall be met
whenever possible:
(1)
For existing development, design practices to retain soil particles
greater than 40 microns on the site (20% reduction) resulting from
a one-year, twenty-four-hour storm event, according to approved procedures,
and assuming no sediment resuspension.
(2)
For street reconstruction, design practices to retain soil particles
greater than 20 microns on the site (40% reduction) resulting from
a one-year, twenty-four-hour storm event, according to approved procedures,
and assuming no sediment resuspension.

of the 1993 Municipal Code)]
This article is adopted under the authority granted by § 62.234,
Wis. Stats.
A.
Findings. The Council finds runoff from land disturbing and subsequent
development of property carries a significant amount of sediment and
other pollutants to the waters and rights-of-way of the state and
this City. This type of activity can also result in a change in runoff
patterns that may have a detrimental effect on water quality and downstream
properties.
B.
Intent. The intent of this article is to require erosion control
practices that will reduce the amount of sediment and other pollutants
leaving sites during land development or land disturbance activities.
This article applies to all land disturbing activities and land development
activities.
C.
Purpose. It is the purpose of this article to preserve the natural
resources; to protect the quality of the waters of the state and the
City; and to protect and promote the health, safety and welfare of
the people, to the extent practicable by minimizing the amount of
sediment, soil loss, and other pollutants carried by runoff or discharged
from land disturbing and subsequent development of property to lakes,
streams and wetlands.

boundary of a lake and 300 feet from a river, natural pool, stream,
pond or wetland.
B.
Erosion and other pollutant control requirements. The following requirements shall be met on all sites described in § 439-28A above.
(1)
Site dewatering. Water pumped from the site shall be treated by control
measures specified in the Wisconsin Construction Site Best Management
Practice Handbook. 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 City administrative
authority. Water may not be discharged in a manner that causes erosion
of the site, adjacent land or receiving channels.
(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 of and not allowed
to be carried by runoff into a receiving channel or storm sewer system.
(3)
Tracking. Each 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. Any sediment reaching
a public or private road shall be removed by street cleaning (not
flushing) before the end or each workday.
(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] below. 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 per second across the disturbed area for the two year, twenty-four-hour storm. Diverted runoff shall be conveyed in a manner that will not erode the conveyance and receiving channels. For allowable velocities in different types of channels, Natural Resources Conservation Service guidelines shall 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 disturbed area on the site shall be controlled by meeting either Subsection B(5)(c)[1] and [2] or Subsection B(5)(c)[1] and [3] below.
[1]
Where activities will result in disturbed ground being left
inactive for 10 or more days, positive controls for keeping all erosion
on site, including such measures as placement of silt fences, hay
bales, detention basins, phased construction or stabilization of the
disturbed ground with temporary or permanent seeding; temporary or
permanent seeding and mulching; sodding or covering with tarps shall
be employed to the satisfaction of the City administrative authority
for the City. Seeding without mulch may be allowed if the seeding
is started and completed between May 1 and September 15. If temporary
seeding is used, a permanent cover shall also be required as part
of the final site stabilization. Seeding or sodding shall be conducted
as specified in the Department of Natural Resources Wisconsin Construction
Site Best Management Practice Handbook or by the City administrative
authority. Variances from the requirements of this subsection may
be granted by the City administrative authority upon application,
but only if the applicant's failure to comply is due to extended periods
of rain or other construction delays beyond the control of the responsible
party.
[2]
For sites with 10 or more acres disturbed at one time or if
a channel originates in the disturbed area, one or more sedimentation
basins shall be constructed in addition to other erosion control measures.
Each sedimentation basin shall be designed and constructed as specified
in the Department of Natural Resources Wisconsin Construction Site
Best Management Practice Handbook.
[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 side slope and down slope 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)
Runoff from sites on slopes of 12% or more may require additional or different controls than listed in Subsection B(5)(c) above. Control measures for such slopes require approval of the City administrative authority.
(e)
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. Straw
bales or filter fence barriers shall be placed immediately on the
down slope side of the piles. If remaining for more than 30 days,
they shall be stabilized by mulching, vegetative cover, tarps or other
means. Where soil or dirt storage piles resulting from in-street utility
repairs are located closer than 25 feet to a roadway or drainage channel,
adequate control measures shall be taken to prevent erodible materials
from entering the adjacent ditch or storm sewer system. Storm drain
inlets must be protected with straw bales or other appropriate filtering
barriers. If any soil or dirt storage pile described in this subsection
is in existence for more than six months, the filter fabric or straw
bales shall be replaced upon orders of the City administrative authority.
At least one landowner or land user controlling or using the
site and desiring to undertake a land disturbing or land developing
activity subject to this article shall submit an application for a
permit along with a control plan or control plan statement as hereinafter
required and pay a permit fee to the City administrative authority
prior to the start of any land disturbing activity. The act of submitting
an application does, as part thereof, authorize the City administrative
authority to enter the site to obtain information required for the
review of the control plan. After the initial review, the applicant
may file supplemental information with the City administrative authority
to comply with directives from the City administrative authority.
