879]
(1)
This article is adopted by the Village Board of Trustees under the
authority granted by § 61.354, Wis. Stats., for villages.
This article supersedes all provisions of an ordinance previously
enacted under § 61.35, Wis. Stats., that relate to stormwater
management regulations. Except as otherwise specified in § 61.354,
Wis. Stats., § 61.35, Wis. Stats., applies to this article
and to any amendments to this article.
(2)
The provisions of this article are deemed not to limit any other
lawful regulatory powers of the same governing body.
(3)
The Village Board of Trustees hereby designates the Village Manager
to administer and enforce the provisions of this article.
(4)
The requirements of this article do not preempt more stringent stormwater
management requirements that may be imposed by any of the following:
(a)
Wisconsin Department of Natural Resources administrative rules,
permits or approvals, including those authorized under §§ 281.16
and 283.33, Wis. Stats.
(b)
Targeted nonagricultural performance standards promulgated in
rules by the Wisconsin Department of Natural Resources under § NR
151.004, Wis. Adm. Code.
(c)
Milwaukee Metropolitan Sewerage District.
The Village Board of Trustees acknowledges that uncontrolled,
post-construction runoff has a significant impact upon water resources
and the health, safety and general welfare of the community and diminishes
the public enjoyment and use of natural resources. Specifically, uncontrolled
post-construction runoff can:
(1)
Degrade physical stream habitat by increasing stream bank erosion,
increasing streambed scour, diminishing groundwater recharge, diminishing
stream base flows and increasing stream temperature.
(2)
Diminish the capacity of lakes and streams to support fish, aquatic
life, recreational and water supply uses by increasing pollutant loading
of sediment, suspended solids, nutrients, heavy metals, bacteria,
pathogens and other urban pollutants.
(3)
Alter wetland communities by changing wetland hydrology and by increasing
pollutant loads.
(4)
Reduce the quality of groundwater by increasing pollutant loading.
(5)
Threaten public health, safety, property and general welfare by overtaxing
storm sewers, drainageways, and other minor drainage facilities.
(6)
Threaten public health, safety, property, and general welfare by
increasing major flood peaks and volumes.
(7)
Undermine floodplain management efforts by increasing the incidence
and levels of flooding.
(8)
Aggravate excessive infiltration and inflow of water into sanitary
sewer connections during peak storm events causing the conveyance
system to surcharge, overflow, or back up into basements.
(1)
Purpose. The general purpose of this article is to establish long-term,
post-construction runoff management requirements that will diminish
the threats to public health, safety, welfare and the aquatic environment.
Specific purposes are to:
(a)
Further the maintenance of safe and healthful conditions.
(b)
Prevent and control the adverse effects of stormwater; prevent
and control soil erosion; prevent and control water pollution; protect
spawning grounds, fish and aquatic life; control building sites, placement
of structures and land uses; preserve ground cover and scenic beauty;
and promote sound economic growth.
(c)
Control exceedance of the safe capacity of existing drainage
facilities and receiving water bodies; prevent undue channel erosion;
and control increases in the scouring and transportation of particulate
matter.
(d)
Minimize the amount of pollutants discharged from the separate
storm sewer to protect the waters of the state.
(2)
Intent. It is the intent of the Village Board of Trustees that this
article regulates post-construction stormwater discharges to waters
of the state. This article may be applied on a site-by-site basis.
The Village Board of Trustees recognizes, however, that the preferred
method of achieving the stormwater performance standards set forth
in this article is through the preparation and implementation of comprehensive,
systems-level stormwater management plans that cover hydrologic units,
such as watersheds, on a municipal and regional scale. Such plans
may prescribe regional stormwater devices, practices or systems, any
of which may be designed to treat runoff from more than one site prior
to discharge to waters of the state. Where such plans are in conformance
with the performance standards developed under § 281.16,
Wis. Stats., for regional stormwater management measures and have
been approved by the Village Board of Trustees, it is the intent of
this article that the approved stormwater management plan be used
to identify post-construction management measures acceptable for the
community.
(1)
Applicability.
(a)
Except as provided under Subsection (1)(b) or (c), the water quality management duties apply to a post-construction site whereupon one acre or more of land-disturbing construction activity occurs during construction, and the water quantity management duties apply to a post-construction site that increases impervious surface by 1/2 acre or more.
(b)
A site that meets any of the criteria in this subsection is
exempt from the water quality requirements of this article:
1.
A post-construction site with less than ten-percent connected
imperviousness, based on the area of land disturbance, provided the
cumulative area of all impervious surfaces is less than one acre.
However, the exemption of this subsection does not include exemption
from the protective area standard of this article.
2.
Agricultural facilities and practices.
3.
Underground utility construction, but not including the construction
of any aboveground structures associated with utility construction.
(c)
Water quantity management duties do not apply if:
1.
Residential infill on a site five acres or less; site is exclusively
residential; net increase in the area of impervious surface is less
than 20% of the area of the site; and each boundary of the site is
contiguous to sites that contain earlier development served by sanitary
sewers, streets, or public water supply when the governmental unit
receives the plans for the new development or parkland, other public
land, a utility right-of-way, or a watercourse.
2.
Sites where area of impervious surface after development or
redevelopment will be 5% or less of the total area of the site.
3.
Recreation trails if the trail is less than or equal to 10 feet
in width and has a continuous pervious buffer at least five feet wide
on each side disregarding interruption by streets, driveways, or other
impervious surfaces crossing the trail.
(d)
Notwithstanding the applicability requirements in Subsection (1)(a), this article applies to post-construction sites of any size that, as determined by the Village Manager, are likely to result in runoff that exceeds the safe capacity of the existing drainage facilities or receiving body of water, causes undue channel erosion, or increases water pollution by scouring or the transportation of particulate matter.

Maximum extent practicable applies when a person who is subject
to a performance standard of this article demonstrates to the Village
Manager'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 responsible party 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.
The following methods shall be used in designing the water quality,
peak discharge, and infiltration components of stormwater practices
needed to meet the water quality and quantity standards of this article:
(1)
Consistent with the technical standards identified, developed or
disseminated by the Wisconsin Department of Natural Resources under
Subchapter V of Chapter NR 151, Wis. Adm. Code.
(2)
Where technical standards have not been identified or developed by
the Wisconsin Department of Natural Resources, other technical standards
may be used, provided that the methods have been approved by the Village
Manager.
(3)
The most recent rainfall data identified by the Southeastern Wisconsin Regional Planning Commission shall be used for the analyses required by Chapter 13 of the Milwaukee Metropolitan Sewerage District rules as implemented and enforced by the Village of Greendale.
Note to Users: Pollutant loading models such as WinSLAMM, or
equivalent methodology as approved by the Village, may be used to
evaluate the efficiency of the design in reducing total suspended
solids. Use the most recent version of the model and the rainfall
files and other parameter files identified for Wisconsin users unless
directed otherwise by the regulatory authority.
(1)
Responsible party. The responsible party shall comply with this section.
(2)
Stormwater management plan. A written stormwater management plan in accordance with § 26.10 shall be developed and implemented for each post-construction site.
(3)
Maintenance of effort. For redevelopment sites where the redevelopment
will be replacing older development that was subject to post-construction
performance standards of NR 151 in effect on or after October 1, 2004,
the responsible party shall meet the total suspended solids reduction,
peak flow control, infiltration, and protective areas standards applicable
to the older development or meet the redevelopment standards of this
article, whichever is more stringent.
(4)
Requirements. The stormwater management plan required under Subsection (2) shall include the following:
(a)
Total suspended solids. BMPs shall be designed, installed and maintained
to control total suspended solids carried in runoff from the post-construction
site as follows:
1.
BMPs shall be designed in accordance with Table 1 or to the
maximum extent practicable as provided in Subsection (4)(a)2. The
design shall be based on an average annual rainfall, as compared to
no runoff management controls.

2.
Maximum extent practicable. If the design cannot meet a total
suspended solids reduction performance standard of Table 1, the stormwater
management plan shall include a written, site-specific explanation
of why the total suspended solids reduction performance standard cannot
be met and why the total suspended solids load will be reduced only
to the maximum extent practicable.
3.
Off-site drainage. When designing BMPs, runoff draining to the
BMP from off-site shall be taken into account in determining the treatment
efficiency of the practice. Any impact on the efficiency shall be
compensated for by increasing the size of the BMP accordingly.
(b)
Water quantity and management of peak runoff.
1.
BMPs shall manage the volume, timing, and peak flow rate of
runoff to prevent increases in the regional flood and stream bank
erosion rates.
2.
These BMPs may be implemented either on-site or off-site as
part of a regional stormwater device, practice or system. The BMP
shall manage runoff from the post-construction site prior to discharge
to waters of the state.
3.
When implemented on a regional basis, the BMPs implemented at
a particular site shall comply with the findings of the relevant local
or regional stormwater management plan, rather than Subsection (4)(b)4
and 5.
4.
The following peak runoff reductions are required:
a.
By design, BMPs shall be employed to maintain or reduce the
one-year, twenty-four-hour post-construction peak runoff discharge
rates to the one-year, twenty-four-hour predevelopment peak runoff
discharge rates, or to the maximum extent practicable.
b.
For the fifty-percent/two-year, twenty-four-hour design storm,
BMPs shall be designed to either maintain or reduce the peak runoff
discharge rates, to the maximum extent practicable, as compared to
predevelopment conditions, or achieve a maximum runoff release rate
of 0.15 cubic feet per second per acre, whichever is more stringent.
c.
Redevelopment.
1)
For development, runoff management shall prevent increases in
the regional flood and stream bank erosion rates.
2)
If demolition or construction during redevelopment will disturb
an area larger than two acres, then the Village of Greendale shall
reduce the runoff rate by the amount listed in Table 2 for the one-percent/one-hundred-year
and fifty-percent/two-year storms, except as provided for in MMSD
Chapter 13.11(5) Rules.

If redevelopment will add 1/2 acre or more of impervious surface,
then the requirements of Subsection (4)(b)4c1 apply rather than Subsection
(4)(b)4c2.
d.
The runoff curve numbers in Table 3 shall be used to represent
the actual predevelopment conditions. Peak discharges shall be calculated
using TR-55 runoff curve number methodology, Atlas 14 precipitation
depths, and the NRCS Wisconsin MSE3 precipitation distribution (for
Milwaukee County). On a case-by-case basis, the Village Manager may
allow the use of TP-40 precipitation depths and the Type II distribution.
Note to Users: For determining compliance with the peak flow
requirement, the Department recommends use of the National Oceanic
and Atmospheric Administration (NOAA) Atlas 14 Precipitation Frequency
Estimates for precipitation depth. The Natural Resources Conservation
Service (NRCS) - Wisconsin has calculated county-specific Atlas 14
precipitation depths, and they are to be used in combination with
the appropriate NRCS MSE3 or MSE4 precipitation distribution. The
NRCS calculated county-specific Atlas 14 precipitation depths and
MSE3 and MSE4 precipitation distributions are available at:

e.
For the one-percent/one-hundred-year, twenty-four-hour design
storm, BMPs shall be designed to achieve a runoff release rate that
is less than or equal to either:
5.
This subsection of the article does not apply to any of the
following:
a.
A post-construction site where the discharge is directly into
a lake over 5,000 acres or a stream or river segment draining more
than 500 square miles.
c.
An in-fill development area less than five acres.
Note to Users: The intent of the peak discharge standard is
to minimize stream bank erosion, under bank-full conditions. For water
quantity concerns, the post-development peak flow rate for the ten-
and one-hundred-year, twenty-four-hour storm events should also be
controlled either at or below predevelopment discharge rates.
(c)
Infiltration.
1.
Best Management Practices. BMPs shall be designed, installed,
and maintained to infiltrate runoff in accordance with the following
or to the maximum extent practicable:
a.
Low imperviousness. For development up to forty-percent connected
imperviousness, such as parks, cemeteries, and low-density residential
development, infiltrate sufficient runoff volume so that the post-development
infiltration volume shall be at least 90% of the predevelopment infiltration
volume, based on an average annual rainfall. However, when designing
appropriate infiltration systems to meet this requirement, no more
than 1% of the post-construction site is required as an effective
infiltration area.
b.
Moderate imperviousness. For development with more than forty-percent
and up to eighty-percent connected imperviousness, such as medium-
and high-density residential, multifamily development, industrial
and institutional development, and office parks, infiltrate sufficient
runoff volume so that the post-development infiltration volume shall
be at least 75% of the predevelopment infiltration volume, based on
an average annual rainfall. However, when designing appropriate infiltration
systems to meet this requirement, no more than 2% of the post-construction
site is required as an effective infiltration area.
c.
High imperviousness. For development with more than eighty-percent
connected imperviousness, such as commercial strip malls, shopping
centers, and commercial downtowns, infiltrate sufficient runoff volume
so that the post-development infiltration volume shall be at least
60% of the predevelopment infiltration volume, based on an average
annual rainfall. However, when designing appropriate infiltration
systems to meet this requirement, no more than 2% of the post-construction
site is required as an effective infiltration area.
2.
Predevelopment. The predevelopment condition shall be the same
as specified in Table 3 of the peak discharge section of this article.
3.
Source areas.
a.
Prohibitions. Runoff from the following areas may not be infiltrated and may not qualify as contributing to meeting the requirements of this section unless demonstrated to meet the conditions identified in § 26.08(4)(c)6:
1)
Areas associated with a tier 1 industrial facility identified
in § NR 216.21(2)(a), including storage, loading and parking.
Rooftops may be infiltrated with the concurrence of the regulatory
authority.
2)
Storage and loading areas of a tier 2 industrial facility identified
in § NR 216.21(2)(b).
Note to Users: Runoff from the employee and guest parking and
rooftop areas of a tier 2 facility may be infiltrated, but runoff
from the parking area may require pretreatment.
3)
Fueling and vehicle maintenance areas. Runoff from rooftops
of fueling and vehicle maintenance areas may be infiltrated with the
concurrence of the regulatory authority.
b.
Exemptions. Runoff from the following areas may be credited
toward meeting the requirement when infiltrated, but the decision
to infiltrate runoff from these source areas is optional:
1)
Parking areas and access roads less than 5,000 square feet for
commercial development.
2)
Parking areas and access roads less than 5,000 square feet for
industrial development not subject to the prohibitions under Subsection
(4)(c)3a.
4)
In-fill development areas less than five acres.
5)
Roads on commercial, industrial and institutional land uses,
and arterial residential roads.
4.
Location of practices.
a.
Prohibitions. Infiltration practices may not be located in the
following areas:
1)
Areas within 1,000 feet upgradient or within 100 feet downgradient
of direct conduits to groundwater.
2)
Areas within 400 feet of a community water system well as specified
in § NR 811.16(4) or within the separation distances listed
in § NR 812.08 for any private well or non-community well
for runoff infiltrated from commercial, including multifamily residential,
industrial and institutional land uses or regional devices for one-
and two-family residential development.
3)
Areas where contaminants of concern, as defined in § NR
720.03(2), are present in the soil through which infiltration will
occur.
b.
Separation distances.
1)
Infiltration practices shall be located so that the characteristics
of the soil and the separation distance between the bottom of the
infiltration system and the elevation of seasonal high groundwater
or the top of bedrock are in accordance with Table 4:

Infiltration rate exemptions. Infiltration practices located
in the following areas may be credited toward meeting the requirements
under the following conditions, but the decision to infiltrate under
these conditions is optional:
1)
Where the infiltration rate of the soil measured at the proposed
bottom of the infiltration system is less than 0.6 inches per hour
using a scientifically credible field test method.
2)
Where the least permeable soil horizon to five feet below the
proposed bottom of the infiltration system using the United States
Department of Agriculture method of soils analysis is one of the following:
sandy clay loam, clay loam, silty clay loam, sandy clay, silty clay,
or clay.
5.
Alternate use. Where alternate uses of runoff are employed,
such as for toilet flushing, laundry, or irrigation or storage on
green roofs where an equivalent portion of the runoff is captured
permanently by rooftop vegetation, such alternate use shall be given
equal credit toward the infiltration volume required by this section.
6.
Groundwater standards.
a.
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. However, if site-specific
information indicates that compliance with a preventive action limit
is not achievable, the infiltration BMP may not be installed or shall
be modified to prevent infiltration to the maximum extent practicable.
b.
Notwithstanding Subsection (4)(c)69, the discharge from BMPs
shall remain below the enforcement standard at the point of standards
application.
7.
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 in accordance with Subsection (4)(c)6.
Pretreatment options may include, but are not limited to, oil and
grease separation, sedimentation, biofiltration, filtration, swales
or filter strips.
8.
Maximum extent practicable. Where the conditions of Subsection (4)(c)3 and 4 limit or restrict the use of infiltration practices, the performance standard of § 26.08(4)(c) shall be met to the maximum extent practicable.
(d)
Protective areas.
1.
Definition. In this section, "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 section, protective area does
not include any area of land adjacent to any stream enclosed within
a pipe or culvert, so that runoff cannot enter the enclosure at this
location.
a.
For outstanding resource waters and exceptional resource waters,
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 wetlands not subject to Subsection (4)(d)1e or f, 50 feet.
e.
For highly susceptible wetlands, 75 feet. Highly susceptible
wetlands include the following types: calcareous fens, sedge meadows,
open and coniferous bogs, low prairies, coniferous swamps, lowland
hardwood swamps, and ephemeral ponds.
f.
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 wetland dominated by invasive species such as reed
canary grass; cultivated hydric soils; and any gravel pits, or dredged
material or fill material disposal sites that take on the attributes
of a wetland.
g.
In Subsection (4)(d)1d to f, 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.
h.
Wetland boundary delineation shall be made in accordance with
§ NR 103.08(1m). This paragraph does not apply to wetlands
that have been completely filled in compliance with all applicable
state and federal regulations. The protective area for wetlands that
have been partially filled in compliance with all applicable state
and federal regulations shall be measured from the wetland boundary
delineation after a fill has been placed. Where there is a legally
authorized wetland fill, the protective area standard need not be
met in that location.
i.
For concentrated flow channels with drainage areas greater than
130 acres, 10 feet.
j.
Notwithstanding Subsection (4)(d)1a to i, the greatest protective
area width shall apply where rivers, streams, lakes and wetlands are
contiguous.
Note to User: A stream or lake is not eligible for a lower protective
area width even if contiguous to a less susceptible wetland.
2.
Applicability. This section applies to post-construction sites
located within a protective area, except those areas exempted pursuant
to Subsection (4)(d)4.
3.
Requirements. The following requirements shall be met:
a.
Impervious surfaces shall be kept out of the protective area
entirely or to the maximum extent practicable. If there is no practical
alternative to locating an impervious surface in the protective area,
the stormwater management plan shall contain a written, site-specific
explanation.
b.
Where land-disturbing construction activity occurs within a
protective area, adequate sod or self-sustaining vegetative cover
of 70% or greater shall be established and maintained where no impervious
surface is present. 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 to Users: It is recommended that seeding of noninvasive
vegetative cover be used in the protective areas. Some invasive plants
that should not be used are listed in Ch. NR 40, Wis. Adm. Code. Flood-
and drought-tolerant vegetation that 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 number A3533, titled "Estimating
Residue Using the Line Transect Method."
c.
BMPs such as filter strips, swales, or wet detention ponds,
that are designed to control pollutants from non-point sources, may
be located in the protective area.
Note to Users: Other laws, such as Ch. 30, Wis. Stats., and
Chs. NR 103, 115, 116 and 117, Wis. Adm. Code, and their associated
review and approval processes may apply in the protective area.
4.
Exemptions. This section does not apply to any of the following:
b.
In-fill development areas less than five acres.
c.
Structures that cross or access surface water such as boat landings,
bridges, and culverts.
d.
Structures constructed in accordance with § 59.692(1v),
Wis. Stats.
e.
Areas of post-construction sites from which the runoff does
not enter the surface water, including wetlands, without first being
treated by a BMP to meet the local ordinance requirements for total
suspended solids and peak flow reduction, except to the extent that
vegetative ground cover is necessary to maintain bank stability.
Note to Users: A vegetated protective area to filter runoff
pollutants from post-construction sites described in Subsection (4)(d)4e
is not necessary since the runoff at that location is treated prior
to entering the surface water. Other practices necessary to meet the
requirements of this section, such as a swale or pond, will need to
be designed and implemented to reduce runoff pollutants prior to runoff
entering a surface water of the state.
(e)
Fueling and maintenance areas. Fueling and vehicle maintenance areas
shall have BMPs designed, installed, and maintained to reduce petroleum
within runoff, so that the runoff that enters waters of the state
contains no visible petroleum sheen, or to the maximum extent practicable.
Note to Users: A combination of the following BMPs may be used:
oil and grease separators, canopies, petroleum spill cleanup materials,
or any other structural or nonstructural method of preventing or treating
petroleum in runoff.
(5)
General considerations for stormwater management measures. The following
considerations shall be observed in on-site and off-site runoff management:
(a)
Natural topography and land cover features such as natural swales,
natural depressions, native soil infiltrating capacity, and natural
groundwater recharge areas shall be preserved and used, to the extent
possible, to meet the requirements of this section.
(b)
Emergency overland flow for all stormwater facilities shall
be provided to prevent exceeding the safe capacity of downstream drainage
facilities and prevent endangerment of downstream property or public
safety.
(6)
BMP location.
(a)
To comply with the performance standards required under § 26.08 of this article, BMPs may be located on-site or off-site as part of a regional stormwater device, practice or system, but shall be installed in accordance with § NR 151.003, Wis. Adm. Code.
(b)
The Village Manager may approve off-site management measures,
provided that all of the following conditions are met:
1.
The Village Manager determines that the post-construction runoff
is covered by a stormwater management system plan that is approved
by the Village of Greendale and that contains management requirements
consistent with the purpose and intent of this article.
2.
The off-site facility meets all of the following conditions:
a.
The facility is in place.
b.
The facility is designed and adequately sized to provide a level
of stormwater control equal to or greater than that which would be
afforded by on-site practices meeting the performance standards of
this article.
c.
The facility has a legally obligated entity responsible for
its long-term operation and maintenance.
(c)
Where a regional treatment option exists such that the Village
Manager exempts the applicant from all or part of the minimum on-site
stormwater management requirements, the applicant shall be required
to pay a fee in an amount determined in negotiation with the Village
Manager. In determining the fee for post-construction runoff, the
Village Manager shall consider an equitable distribution of the cost
for land, engineering design, construction, and maintenance of the
regional treatment option.
(7)
Additional requirements. The Village Manager may establish stormwater
management requirements more stringent than those set forth in this
article if the Village Manager determines that the requirements are
needed to control stormwater quantity or control flooding, comply
with federally approved total maximum daily load requirements, or
control pollutants associated with existing development or redevelopment.
(8)
Credit for removal of impervious surfaces.
(a)
Same site credit.
1.
The Village Manager may use the removal of pavement, covered
structures, or other impervious surfaces at the same property to calculate
the net post-construction impervious acreage and corresponding water
quantity management duties to meet MMSD 13.11 requirements. The credit
does not change the water quantity management requirements under Subsection
(4)(b)4a and b.
2.
Credit may equal, but not be larger than, the acreage of impervious surfaces removed when runoff release rates and detention are the best management practices utilized at the site. When best management practices with a higher order of preference are utilized in lieu of detention, equivalent credit may be granted as determined by the Village Manager with the concurrence of the MMSD. Credit for reducing impervious surfaces at a site, not utilized by the development on the site, belongs to the Village Manager and may be banked for allocation to other development within the watershed under Subsection (8)(b).
(b)
Dispersed site in same watershed credit. The Village Manager
may bank the removal of impervious surface, which individually must
be 1/2 acre or more, within the same watershed, where the volume,
timing and peak flow runoff will be distributed over the critical
time sufficient to assure the level of protection provided by MMSD
flood abatement projects will not be reduced. The Village Manager
may allocate banked credit to promote a policy of smart growth. The
total acreage banked or allocated, or both, shall be reported, by
watershed or subwatershed, annually to the MMSD for concurrence. The
credit does not change the water quantity management requirements
under Subsection (4)(b)4a and b.
(1)
Permit required. No responsible party may undertake a land-disturbing
construction activity without receiving a post-construction runoff
permit from the Village Manager prior to commencing the proposed activity.
(2)
Permit application and fees. Unless specifically excluded by this
article, any responsible party desiring a permit shall submit to the
Village Manager a permit application on a form provided by the Village
Manager for that purpose.

is received to inform the applicant that the stormwater management
plan and maintenance agreement are either approved or disapproved.
(e)
Failure by the Village Manager to inform the permit applicant
of a decision within 60 business days of a required submittal shall
be deemed to mean approval of the submittal, and the applicant may
proceed as if a permit had been issued.
(4)
Permit requirements. All permits issued under this article shall be subject to the following conditions, and holders of permits issued under this article shall be deemed to have accepted these conditions. The Village Manager may suspend or revoke a permit for violation of a permit condition, following written notification of the responsible party. An action by the Village Manager to suspend or revoke this permit may be appealed in accordance with § 26.15.
(a)
Compliance with this permit does not relieve the responsible
party of the responsibility to comply with other applicable federal,
state, and local laws and regulations.
(b)
The responsible party shall design and install all structural
and nonstructural stormwater management measures in accordance with
the approved stormwater management plan and this permit.
(c)

If required as a special condition under Subsection (5), the responsible party shall make additional notification according to a schedule set forth by the Village Manager so that practice installations can be inspected during construction.
(d)
Practice installations required as part of this article shall
be certified "as built" or "record" drawings by a licensed professional
engineer. Completed stormwater management practices must pass a final
inspection by the Village Manager or its designee to determine if
they are in accordance with the approved stormwater management plan
and ordinance. The Village Manager or its designee shall notify the
responsible party in writing of any changes required in such practices
to bring them into compliance with the conditions of this permit.
(e)
The responsible party shall notify the Village Manager of any
significant modifications it intends to make to an approved stormwater
management plan. The Village Manager may require that the proposed
modifications be submitted to it for approval prior to incorporation
into the stormwater management plan and execution by the responsible
party.
(f)
The responsible party shall maintain all stormwater management
practices in accordance with the stormwater management plan until
the practices either become the responsibility of the Village Board
of Trustees, or are transferred to subsequent private owners as specified
in the approved maintenance agreement.
(g)

VII of Ch. 66, Wis. Stats., or to charging such costs against the financial guarantee posted under § 26.12.
(h)
If so directed by the Village Manager, the responsible party
shall repair at the responsible party's own expense all damage
to adjoining municipal facilities and drainageways caused by runoff,
where such damage is caused by activities that are not in compliance
with the approved stormwater management plan.
(i)
The responsible party shall permit property access to the Village
Manager or its designee for the purpose of inspecting the property
for compliance with the approved stormwater management plan and this
permit.
(j)
