area of the Village where each created and existing , reduced in size parcel,
lot or tract is served by municipal sewer and water at the time of division.
No division of land within the Village or within its extraterritorial
jurisdiction shall be permitted if it results in a subdivision, unless a plat
of the subdivision is submitted and approved in accordance with this article
and ch. 236, Wis. Stats.
No subdivision shall be approved which does not conform to Village zoning
rules and regulations and the Comprehensive Plan of the Village , either within
the Village limits or in its extraterritorial planning area.
A.
The subdivider shall be responsible for the installation
or construction of all improvements required by the Plan Commission with the
exception of sidewalks and streetlighting.
B.
For all subdivision improvements required to be installed
by him/her, the subdivider shall provide satisfactory proof that he/she has
contracted to install such improvements or shall file a performance bond insuring
installment of such improvements within the time required by the Plan Commission
and Board.
C.
The specifications for all improvements shall be approved
by the Plan Commission. Prior to either acceptance of the improvement by the
Board or release of the subdivider's bond, all improvements shall be inspected
and found to have been installed according to the specifications.
A.
Before submitting a preliminary plat to the approval process under § 218-8, each subdivider is encouraged to prepare, for review by the Village administrative staff, a concept design of the proposed subdivision. Said design shall contain such information as: site location, showing adjacent streets and subdivisions; boundaries of proposed subdivision; proposed street layout; approximate topographic features; proposed lot layout; easements, existing and proposed; and proposed surfaced water drainage.
B.
No fee shall be charged for the concept design review.
The purpose shall be to provide a general overview of the compliance of the
proposed subdivision with existing rules and regulations.
A.
The subdivider shall submit to the Plan Commission, and
to those agencies having the authority to object to plats under the provisions
of ch. 236, Wis. Stats., a preliminary plat based upon an accurate exterior
boundary survey by a registered land surveyor which shall show clearly the
proposed subdivision at a scale of not more that one inch per 100 feet, having
two-foot contour intervals, identify proposed improvements (grading, tree
planting, paving, installation of facilities and dedications of land) and
easements which the subdivider proposes to establish. The subdivider shall
also indicate by accompanying letter a time or times when the improvements
will be constructed or provided. Any proposed restrictive covenants for the
land involved shall be submitted for review as pertaining to their compliance
with Village regulations.
B.

and size and extent of improvements which subdivider shall be required to
construct, the Plan Commission, on behalf of the Village, and subdivider shall
enter into a development contract under the terms of which the subdivider
shall agree to his/her responsibilities as to subdivision improvements. In
said contract the subdivider shall bind himself/herself to provide either
a sum certain in cash, certificates of deposit or a bond to guarantee faithful
performance in accord with the contract. The failure of the subdivider to
act consistent with the contract prior to final plat approval shall constitute
cause for refusal to issue building or occupancy permits for lots created
by the subdivision.
D.
Approval of the preliminary plat and execution of a development
contract shall entitle the subdivider to final approval of the layout shown
by such plat, provided that the final plat conforms substantially to such
layout and conditions of approval have been met.
E.
No preliminary plat shall be approved which does not
conform in all respects with applicable ordinances of the Village, including
but not limited to zoning, building construction, streets, sidewalks and utilities.
A.
Final plats shall be submitted to the Plan Commission
within six months of preliminary plat acceptance unless this requirement is
waived, in writing, by the Plan Commission.
B.
The final plat shall conform to the preliminary plat
as approved and to the requirements of all applicable ordinances and state
laws and shall be submitted for certification by those agencies having the
authority to object to the plat as provided by § 236.12(2), Wis.
Stats.
C.
The final plat shall be accompanied by detailed construction plans of all improvements, together with an executed copy of the development contract required under § 218-8C.
D.
The final plat shall be presented to the Plan Commission
at its regular meeting prior to the meeting at which it is to be considered
and shall be accepted or rejected by the Plan Commission and the Board within
60 days of its submission, unless the time is extended by an agreement with
the subdivider. Reasons for rejection shall be stated in the minutes of the
Board meeting, and a copy of such reasons shall be given to the subdivider.
E.
Approved final plats shall be recorded in accordance
with the statutory requirements prior to the time that lots are offered for
sale, reference is made to the map for sale purposes or use is made of lot
and block numbers shown on the plat.
F.
If the original of the final plat has been filed with
another approving authority, the subdivider shall file a true copy of such
plat with the Village in lieu of the original. Before the approval of the
Plan Commission and Board will be inscribed on the original of the final plat,
the surveyor or subdivider shall certify the respects in which the original
of the final plat differs from the true copy, and all modifications shall
first be approved.
A.

to the approval of the Plan Commission, the maximum center-line grade of any
street or public way shall not exceed the following:
(2)
The grade of any street shall not exceed 12% or be less
than 0.5%. Street grades shall be established wherever practicable so as to
avoid excessive grading, removal of ground cover and tree growth and general
leveling of the topography.
D.
Curves. When a continuous street center line deflects
at any one point by more than 10%, a circular curve shall be introduced having
a radius of curvature on such center line of not less that the following:
E.
Continuation. Streets shall be laid out to provide for
continuation wherever topographic and other physical conditions permit.
F.
Through traffic on minor streets discouraged. Minor streets
shall be laid out so as to discourage their use by through traffic.
G.
Number of intersections. The number of intersections
of minor streets with major streets shall be reduced to the practical minimum
consistent with circulation needs and safety requirements.
H.
Where a subdivision abuts or contains an existing or
proposed arterial highway, the Plan Commission shall require a frontage road,
nonaccess reservation along the rear of the property contiguous to such highway
or such other treatment as may be necessary to ensure safe, efficient traffic
flow and adequate protection of residential properties.
I.
Reserve strips controlling access to streets shall be
prohibited.
J.
A tangent at least 100 feet long shall be required between
reverse curves on arterial and collector streets.

with a turnaround having an outside roadway diameter of at least 80 feet and
a street property line of 100 feet.
N.
Where possible, lot lines shall be perpendicular to the
street line and to the tangent at the lot corner or curved streets.
O.
Lots shall follow, rather than cross, municipal boundary
lines whenever practicable.
P.
No street names shall be used which duplicate or may
be confused with the names of existing streets. Street names shall be subject
to the approval of the Plan Commission.
A.
General. The lengths, widths and shapes of blocks shall
be appropriate for the topography and the type of development contemplated.
B.
Sidewalks. To provide access and circulation to community
facilities, sidewalks shall be designed by the subdivider along both sides
of streets and, where a block exceeds 1,000 feet in length, through the center
of blocks. Center crosswalks shall not be less than 10 feet wide. The subdivider
shall install the center crosswalks where required. The Plan Commission, in
consultation with the subdivider and taking into consideration public welfare
and safety concerns, together with aesthetics, both in the subdivision itself
and throughout the Village, may modify these requirements on a case-by-case
basis.
C.
Subdivision lots shall be in conformance with the area
and width requirements of Village zoning rules and regulations. Area and width
shall conform to town zoning ordinances and Chapter H65, Wisconsin Administrative
Code.
D.
The Plan Commission shall exercise, on behalf of the
Village, approval authority as to the location and species of trees which
may be planted by the subdivider or successors in interest in boulevards or
streets created by the act of subdividing.
A.
In accordance with specifications approved by the Plan
Commission, the subdivider shall provide for each lot the following:
(1)
Adequate sewer and water facilities.
(2)
Streets, of urban design with base and subbase preparation
done to meet WI DOT standards for the proposed and/or anticipated use.
(3)
Paving, done in asphaltic or portland concrete.
(4)
Curb and gutter, done in a 6-24 design of portland concrete.
(5)
Surface water drainage and/or storage structures, meeting
all state and local regulations.
(6)
Streetlighting facilities.
B.
The installation of curb and gutter shall be waived where
rural road sections have been approved by the Plan Commission.
C.
It shall be the responsibility of the subdivider to design adequate street lighting for the entire subdivision so as to fulfill Subsection A(6) above. Insofar as the Village shall be responsible for its installation, the Plan Commission shall, on its behalf, approve all streetlighting plans.
D.
Each subdivision approved of under this article shall
be designed so as to require that all utilities' service lines shall be placed
underground.
A.
The Plan Commission shall require easements for poles,
wires, conduits, storm and sanitary sewers, gas, water and head mains or other
utility lines. Easements for utility services such as those enumerated shall
be at least 10 feet wide and may run across lots or alongside of rear lot
lines, subject to the preference that easements be located along the rear
lot lines. No buildings or other structures shall be erected upon or over
these easements. In addition, a one-foot-wide easement shall be dedicated
at and immediately behind the front lot line for installation by the Village
Water Utility of a waterline cut off valve.
B.
The Plan Commission shall require that easements or drainageways
be provided where a subdivision includes a segment or segments of watercourses,
drainageways, channels or streams.
A.
During the preliminary plat review process, the Plan
Commission shall take into consideration the location of the proposed subdivision
as it relates to existing parks, open spaces and public grounds, the site
of the proposed subdivision and the potential population on the projected
lots in determining whether and to what extent a dedication shall be required
for public recreational and open space needs. In making this determination,
the Plan Commission may require that up to, but not exceeding, 10% of the
total land area of the proposed plat or a sum of money equivalent to the average
land value of the subdivision when platted, as agreed upon and between the
subdivider and the Village or as determined by a real estate appraiser retained
by the Village, be dedicated to the Village.
B.
In the specific case of a subdivision in which multifamily
housing units will or may be constructed, the subdivider shall establish an
area of land of sufficient size to be used as a tot lot or playground for
children. The Plan Commission shall determine its size as based upon the projected
population of the multifamily housing units which could or may be built in
the subdivision, using the maximum number of potential units as would be permitted
under Village zoning regulations. In the sole description of the Village,
it may or may not decide to accept a dedication of a tot lot. In the event
that it does not decide to accept such dedication, the subdivider shall take
adequate legal steps to make it available for use by residents of the subdivision.
Where the Plan Commission finds strict compliance with these regulations
shall not accomplish the purposes of the Village subdivision chapter or shall
result in expenses or physical layout requirements inordinate to the scope
of the proposed subdivision, it shall recommend to the Board such exceptions
to the chapter so that substantial justice shall be done and the public interest
secured, provided that such exceptions shall not have the effect of nullifying
the intent and purpose of this article, and provided that the Plan Commission
shall not recommend exceptions to the regulations of this article unless it
makes findings based upon the evidence presented to it in each specific case
that:
A.
The granting of the exception shall not be detrimental
to the public safety, health or welfare or injurious to other property or
improvements in the neighborhood in which the subdivision is located.
B.
The conditions upon which the request for an exception
is based are unique to the subdivision or the individual lot therein for which
the exception is sought and are not applicable, generally, to other property
in the Village.
C.
Because of the particular physical surroundings, shape
or topographical conditions of the specific subdivision or the individual
lot therein involved, a hardship to the owner would result if the strict letter
of the regulations were enforced. For purposes of this section, hardship shall
not include economic factors personal to the subdivider or his/her successors
in interest. It shall be limited to physical inability to use the property
in question to purposes permissible in the zoning district in which the subdivision
is situated.
A.
Pursuant to § 61.34(1), Wis. Stats., in the interest of the government and good order of and for the prudent management of the Village finances and for the convenience of the public it is deemed to be in the public's best interest to require all persons who apply for and receive subdivision approvals where as a condition to the granting of such approval it is required that an improvement for public use and benefit shall be installed, built or constructed or other specified performance is required, the subdivider shall, in accord with Subsection B, below, file a bond or irrevocable letter of credit with the Village Clerk guaranteeing his/her performance. This section is for the expressed purposes of ensuring that subdividers complete agreed upon obligations to the Village and to prevent the Village, should it be required to complete performance of conditions, from having to use taxpayers monies to do so.
B.
Each subdivider of lands who obtains approval of a land
division from the Village which is conditioned upon his/her/its faithful performance
in favor of the public, including but not limited to the installation of improvements
or performance of other specified obligations, shall be required to post a
bond or irrevocable letter of credit in favor of the Village to guarantee
his/her/its performance in accord with the required specifications. Each such
bond or letter of credit shall be in such amount as will fully indemnify the
Village against the cost of securing the completion of such performance or
in such lesser amount as the Village deems to be adequate. As progress toward
accomplishing the performance is made, in the sole discretion of the Village,
the amount of the bond or letter of credit may be reduced.
If, pursuant to the terms of this article, a development agreement is
required to be executed by the subdivider, or if in order to comply with terms
and conditions of a conditional use permit or to meet requirements resulting
from a rezoning certain obligations are imposed upon the subdivider, the subdivider
shall be required to execute a development agreement which shall be drafted
in such a form as to fulfill the objectives or standards of the Village. Such
an agreement may include, but shall not be limited to, terms and conditions
such as the timing of performance or installation of improvements, the posting
of adequate performance bonds, penalties for nonperformance and the quality
or quantity of materials or supplies to be incorporated in required improvements.
The failure or refusal of a subdivider to execute such an agreement shall
constitute grounds for denial of or cessation of processing of a subdivision
application under this article.
The Building Inspector or his or her designated representative shall
see that the provisions of this article are enforced. No land use permit shall
be issued for construction on any lot until the final plat for the subdivision
has been duly recorded or a certified survey map is recorded.
In designing a subdivision, the subdivider shall comply with all applicable
state and federal rules and regulations. Failure to do so shall constitute
grounds for refusal to grant final approval of plat.
Any person who shall violate any provision of this article or any order, rule or regulation made hereunder shall be subject to a penalty as provided in § 1-19 of this Code.
[Added 3-14-2006 by Ord. No. 06-05]
A.
This article is adopted by the Village Board under the
authority granted by § 61.354, Wis. Stats. 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.
B.
The provisions of this article are deemed not to limit
any other lawful regulatory powers of the same Village Board.
C.
The Village Board hereby designates the Village Administrator
to administer and enforce the provisions of this article.
D.
The requirements of this article do not preempt more
stringent stormwater management requirements that may be imposed by any of
the following:
(1)
Wisconsin Department of Natural Resources administrative
rules, permits or approvals including those authorized under §§ 281.16
and 283.33, Wis. Stats.
(2)
Targeted nonagricultural performance standards promulgated
in rules by the Wisconsin Department of Natural Resources under NR 151.004,
Wis. Adm. Code.
The Village Board finds that uncontrolled, postconstruction 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 postconstruction runoff can:
A.
Degrade physical stream habitat by increasing stream
bank erosion, increasing streambed scour, diminishing groundwater recharge,
diminishing stream base flows and increasing stream temperature.
B.
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.
C.
Alter wetland communities by changing wetland hydrology
and by increasing pollutant loads.
D.
Reduce the quality of groundwater by increasing pollutant
loading.
E.
Threaten public health, safety, property and general
welfare by overtaxing storm sewers, drainageways, and other minor drainage
facilities.
F.
Threaten public health, safety, property and general
welfare by increasing major flood peaks and volumes.
G.
Undermine floodplain management efforts by increasing
the incidence and levels of flooding.
A.
Purpose. The general purpose of this article is to establish
long-term, postconstruction runoff management requirements that will diminish
the threats to public health, safety, welfare and the aquatic environment.
Specific purposes are to:
(1)
Further the maintenance of safe and healthful conditions.
(2)
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.
(3)
Control exceedance of the safe capacity of existing drainage
facilities and receiving water bodies; prevent undue channel erosion; control
increases in the scouring and transportation of particulate matter; and prevent
conditions that endanger downstream property.
B.
Intent. It is the intent of the Village Board that this
article regulates postconstruction stormwater discharges to waters of the
state. This article may be applied on a site-by-site basis. The Village Board
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, it is the intent of this article that the approved plan be
used to identify postconstruction management measures acceptable for the community.
A.
Applicability.
(1)
Where not otherwise limited by law, this article applies after final stabilization to a site of land-disturbing construction activity meeting any of the criteria in this subsection, unless the site is otherwise exempt under Subsection A(2).
(2)
A site that meets any of the criteria in this subsection
is exempt from the requirements of this article.
(a)
A redevelopment postconstruction site with no increase
in exposed parking lots or roads.
(b)
A postconstruction site with less than 10% connected
imperviousness based on complete development of the postconstruction site,
provided the cumulative area of all parking lots and rooftops is less than
one acre.
(c)
Nonpoint discharges from agricultural facilities and
practices.
(d)
Nonpoint discharges from silviculture activities.
(e)
Routine maintenance for project sites under five acres
of land disturbance if performed to maintain the original line and grade,
hydraulic capacity or original purpose of the facility.
(f)
Underground utility construction such as water, sewer
and fiberoptic lines. This exemption does not apply to the construction of
any aboveground structures associated with utility construction.
(3)
Notwithstanding the applicability requirements in Subsection A(1), this article applies to postconstruction sites of any size that, in the opinion of the Village Administrator, are likely to result in runoff that exceeds the safe capacity of the existing drainage facilities or receiving body of water, that cause undue channel erosion, that increase water pollution by scouring or the transportation of particulate matter or that endanger property or public safety.
B.
Jurisdiction. This article applies to postconstruction
sites within the boundaries and jurisdiction of the Village of Osceola as
well as the extraterritorial division of land subject to an ordinance enacted
pursuant to § 236.45(2) and (3), Wis. Stats.
C.
Exclusions. This article is not applicable to activities
conducted by a state agency, as defined under § 227.01(1), Wis.
Stats., which is subject to the state plan promulgated or a memorandum of
understanding entered into under § 281.33(2), Wis. Stats.

C.
In this article, the following year and location has
been selected as average annual rainfall(s): Minneapolis, 1959 (March 13 -
November 4).
A.
Responsible party. The responsible party shall implement
a postconstruction stormwater management plan that incorporates the requirements
of this section.
B.
Plan. A written stormwater management plan in accordance with § 218-29 shall be developed and implemented for each postconstruction site.
C.

(1)
Total suspended solids. BMPs shall be designed, installed
and maintained to control total suspended solids carried in runoff from the
postconstruction site as follows:
(a)
For new development, by design, reduce, to the maximum
extent practicable, the total suspended solids load by 80%, based on the average
annual rainfall, as compared to no runoff management controls. No person shall
be required to exceed an eighty-percent total suspended solids reduction to
meet the requirements of this subsection.
(b)
For redevelopment, by design, reduce, to the maximum
extent practicable, the total suspended solids load by 40%, based on the average
annual rainfall, as compared to no runoff management controls. No person shall
be required to exceed a forty-percent total suspended solids reduction to
meet the requirements of this subsection.
(c)
For in-fill development under five acres that occurs
within 10 years after the effective date of this article, by design, reduce,
to the maximum extent practicable, the total suspended solids load by 40%,
based on an average annual rainfall, as compared to no runoff management controls.
No person shall be required to exceed a forty-percent total suspended solids
reduction to meet the requirements of this subsection.
(d)
For in-fill development that occurs 10 or more years
after the effective date of this rule (March 14, 2006), by design, reduce,
to the maximum extent practicable, the total suspended solids load by 80%,
based on an average annual rainfall, as compared to no runoff management controls.
No person shall be required to exceed an eighty-percent total suspended solids
reduction to meet the requirements of this subsection.
(e)
Notwithstanding Subsection C(1)(a) through (d), if the design cannot achieve the applicable total suspended solids reduction specified, the stormwater management plan shall include a written and site-specific explanation why that level of reduction is not attained and the total suspended solids load shall be reduced to the maximum extent practicable.
(2)
Peak discharge.
(a)
By design, BMPs shall be employed to maintain or reduce
the peak runoff discharge rates, to the maximum extent practicable, as compared
to predevelopment conditions for the two-year, twenty-four-hour design storm
applicable to the postconstruction site. Predevelopment conditions shall assume
"good hydrologic conditions" for appropriate land covers as identified in
TR-55 or an equivalent methodology. The meaning of "hydrologic soil group"
and "runoff curve number" are as determined in TR-55. However, when predevelopment
land cover is cropland, rather than using TR-55 values for cropland, the runoff
curve numbers in Table 1 shall be used.

shallow marshes, deep marshes, and seasonally flooded basins. Wetland boundary
delineations shall be made in accordance with NR 103.08(1m). 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.
[5]
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.
[6]

[1]
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.
[2]
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.
[3]

Wis. Stats.
[5]
Postconstruction sites from which runoff does not enter
the surface water, except to the extent that vegetative ground cover is necessary
to maintain bank stability.
(5)
Fueling and vehicle maintenance areas. Fueling and vehicle
maintenance areas shall, to the maximum extent practicable, have BMPs designed,
installed and maintained to reduce petroleum within runoff, such that the
runoff that enters waters of the state contains no visible petroleum sheen.
(6)
Swale treatment for transportation facilities.
(a)
Applicability. Except as provided in Subsection C(6)(b), transportation facilities that use swales for runoff conveyance and pollutant removal meet all of the requirements of this section, if the swales are designed to the maximum extent practicable to do all of the following:
[1]
Be vegetated. However, where appropriate, nonvegetative
measures may be employed to prevent erosion or provide for runoff treatment,
such as rock riprap stabilization or check dams.
[2]
Carry runoff through a swale for 200 feet or more in
length that is designed with a flow velocity no greater than 1.5 feet per
second for the peak flow generated using either a two-year, twenty-four-hour
design storm or a two-year storm with a duration equal to the time of concentration
as appropriate. If a swale of 200 feet in length cannot be designed with a
flow velocity of 1.5 feet per second or less, then the flow velocity shall
be reduced to the maximum extent practicable.
(b)
Exemptions. The Village Administrator may, consistent
with water quality standards, require other provisions of this section to
be met on a transportation facility with an average daily travel of vehicles
greater than 2,500 and where the initial surface water of the state that the
runoff directly enters is any of the following:
[1]
An outstanding resource water.
