COMMON COUNCIL Minutes 20090512-Attachment
Please find the following changes that are required to
effectively remove the Conservation Preservation zoning from
the City’s Chapter 17 and Chapter 18 Municipal Codes.
Chapter 17 Changes:
8.39 -CP CONSERVATION PRESERVATION
(1) STATEMENT OF INTENT
This district is intended to correlate with the City’s adopted 2020 Comprehensive Plan Future
Land Use Map. Areas of the 2020 Future Land Use Map display the requirement for certain
parcels to develop according to conservation preservation principles found in the City’s
Chapter 18 Land Division Ordinance. Those parcels under that requirement have the –CP
Conservation Preservation zoning district attached to the existing zoning district. The 2020
Comprehensive Plan and the –CP Conservation Preservation zoning district were
implemented as part of the adoption of the City’s 2020 Comprehensive Plan and are intended
to ensure that the rural and open space areas in Muskego will continue to exist for future
generations in order to balance the urban and rural atmospheres that presently exist in the
community.
(2) BASIC REGULATIONS
Land divisions must follow the Conservation Preservation Subdivision principles
regulated in the City’s Chapter 18 Land Division Ordinance. Further, the procedures
and basis for approvals are the same as found in Sections 10.03 and 10.04 of this
ordinance regulating Conservation Planned Development Districts. Some
characteristics of parcels in a Conservation Preservation Subdivision are found

Commission to comply with the spirit and intent of this ordinance and finding that a change would
not be contrary to the general welfare and economic prosperity to the City of immediate
neighborhood.
1 Along any boundary line no less than 50 feet unless otherwise modified by Planning Commission to
comply with the spirit and intent of this ordinance and finding that a change would not be contrary to
the general welfare and economic prosperity to the City of immediate neighborhood.
2 Open space must be at least 60% of the gross acreage of the development and each private lot must
maintain at least 75% open space.
*See Section 5
(3) Permitted Uses
A. PERMITTED USES BY RIGHT
1. Single-family residential related uses (No multi-family residential related
uses).
2. Any use permitted by the base district.
B. PERMITTED ACCESSORY USES
Any accessory use permitted by the base district.
C. PERMITTED BY CONDITIONAL GRANT
1. Any conditional use permitted by the base district.
2. Minor land division:
A proposed land division in the –CP zoning district that wishes to divide only a portion of
parcel while allowing the remaining parent parcel to be reserved for future conservation
preservation design standards may only do so by the approval of a Conditional Use Grant
that runs with the divided lands. The developer must demonstrate to the Planning
Commission the future development of the parent parcels. An approved conditional use
grant allowing such a land division shall demonstrate that any future land division of the
parcel(s) shall be consistent with the Conservation Preservation Land Division
procedures in Chapter 18 of the City of Muskego Municipal Code. A yield plan and
concept plan must show how the parcel may be divided in the future to meet the City
Conservation Preservation Land Division procedures. The developer will have to receive
approval of a conditional use grant, that runs with the lands, and requires that future
development of the parent parcels is restricted to the yield analysis and concept plans that
were approved along with the minor land division in order to ensure that the principles of
the adopted Comprehensive Plan is followed in relation to Conservation Preservation
Subdivisions.
D. SPECIAL REGULATIONS
Land divisions requesting to not follow the conservation preservation principles found
herein and in the Chapter 18 Land Division Ordinance may make such a request to the
Planning Commission and Common Council. The Common Council shall act on a
request after first receiving a recommendation from the City’s Planning Commission. A
petitioner for such a request must demonstrate that a conventional subdivision or minor
land division for a given area is in the better interest of the City compared to the
objectives found in the City’s Comprehensive Plan that deal with the promotion of
maintaining the community’s conservation, agricultural, and open space resources while
ensuring a quality rural atmosphere for the present and future residents. A petitioner must
also demonstrate that a conservation subdivision or minor land division will not feasibly
work in a given area.
E. -CP Approvals and Requirements
Land divisions that receive approvals under the –CP ordinance will be listed herein with
their approval dates and associated requirements of their approvals. The information
provided in 8.39(3)E may be amended as approvals are given and does not need to follow
the restrictions of code amendments that the rest of Chapter 17 requires if the material
added is of non-material notes:
Section 17: 10.01(3) change:
Note: This section applies to areas requested to be rezoned to a CPD Conservation Planned
Development District and those existing CPD Conservation Planned Development Districts.
Parcels with the –CP Conservation Preservation zoning designation are allowed the conservation
planned development principles by right, although they follow the same requirements found
herein Section 10.
Section 17: 10.02(1) change:
Size Allowed: For the purpose of this Ordinance all Conservation Planned Development Projects
shall require be limited to residential developments on parent parcels of not less than the size
653,400 square feet and the minimum required a minimum open space for a CPD is of 50% 60%
of the gross acreage (Rights-of-way shall not count towards open space requirements. stormwater
outlots may count towards open space requirements, subject to Planning Commission approval,
when they are subject to deed restrictions, easements or open space management plans):
Section 17: 10.02(3)(C)3 change:
For parcels less than forty (40) eighty (80) acres in area, the maximum bonus permitted is the
greater of three (3) four (4) parcels or 15% of the base development density. For parcels
between forty (40) and eighty (80) acres in area, the maximum bonus permitted is five (5)
parcels. For parcels eighty (80) acres or greater in area, the maximum bonus permitted is the
greater of six (6)four (4) parcels or 20% of the base development density. All development yield
bonuses shall be calculated to the nearest one-hundredth. In cases where the total combined
development yield bonus results in a fraction, all such fractions shall be rounded up to the next
whole number. All parcels shown in a developer’s yield analysis must demonstrate that each
parcel could actually be developed on the site proposed. Thus, each yield parcel must show that
adequate water, sewer, stormwater management, and buildable area is present and attainable to
the Planning Commission.
The base development density for an EA Exclusive Agriculture or A Agricultural zoned lot is
based upon a rate of at least 120,000 square feet per lot (300 feet in width). The base development
density for any other piece of land is based on the existing minimum zoning requirements OR the
minimum Comprehensive Plan density requirements, whichever is stricter. All parcels shown in a
developer’s yield analysis must demonstrate that each parcel could actually be developed on the
site proposed. Thus, each yield parcel must show that adequate water, sewer, stormwater
management, and buildable area are present and attainable to the Planning Commission.
Section 18: 18.08: Definitions change:

60% open space, and where the natural features of the land are maintained to the greatest extent
possible.
SUBDIVISION, CONSERVATION. A housing development constructed under the auspices of
the CPD Conservation Planned Development Zoning District, in a rural setting comprised of at

1). Development yield analysis. The Subdivider shall submit a table showing the
maximum number of dwelling units that would be permitted under the City zoning
ordinance, consistent with the minimum lot size, lot widths, set backs, and other
provisions of the zoning ordinance and compare it to the number of dwelling units
proposed. Land/lots that are undevelopable because of other laws and ordinances that
prohibit development in certain areas (e. g. floodplains, wetlands, steep slopes, and
drainage ways) or due to unavailability of proper services (unable to support public
facilities (sewer/water) shall be excluded from the development yield analysis,
however, some undevelopable lands may be allowed as easements on lots within the
Development Yield Analysis as long as build able area is found on each parcel depicted
and Planning Commission allows. The developer must demonstrate that each lot in the
yield analysis would be able to be supported as a viable residential lot producing any
mechanisms necessary that the Planning Commission may request to make this
determination.
The base development density for an EA Exclusive Agriculture or A Agricultural zoned
lot is based upon a rate of at least 120,000 square feet per lot. The base development
density for any other piece of land is based on the existing minimum zoning
requirements OR the minimum Comprehensive Plan density requirements, whichever is
stricter. All parcels shown in a developer’s yield analysis must demonstrate that each
parcel could actually be developed on the site proposed. Thus, each yield parcel must
show that adequate water, sewer, stormwater management, and buildable area are
present and attainable to the Planning Commission.
3. Site analysis and concept plan. Using the inventory provided in section 18.31(3)(k)(1)
above, the development yield analysis provided in section 18.31(3)(i)(2) above, and
applying the design standards specified in section 4 of this ordinance, the subdivider shall
submit a concept plan including at least the following information at a scale of no less than
one inch = 50 feet:

f. Preliminary development pads showing areas for lawns, pavement, buildings,
and grading.
g. Proposed methods for ownership and management of open space.
h. Calculations showing the appropriate amount of open space preservation for a
Conservation Subdivision (60%).
a. A proposed land division in the –CP zoning district that wishes to divide only a
portion of parcel while allowing the remaining parent parcel to be reserved for
future conservation preservation design standards may only do so by the
approval of a Conditional Use Grant that runs with the divided lands. The
developer must demonstrate to the Planning Commission the future development
of the parent parcels. An approved conditional use grant allowing such a land
division shall demonstrate that any future land division of the parcel(s) shall be
consistent with the Conservation Preservation Land Division procedures in
Chapter 18 of the City of Muskego Municipal Code. A yield plan and concept
plan must show how the parcel may be divided in the future to meet the City
Conservation Preservation Land Division procedures. The developer will have
to receive approval of a conditional use grant, that runs with the lands, and
requires that future development of the parent parcels is restricted to the yield
analysis and concept plans that were approved along with the minor land
division in order to ensure that the principles of the adopted Comprehensive Plan
is followed in relation to Conservation Preservation Subdivisions.
4. General location map. The subdivider shall submit a map showing the
general outlines of existing buildings, land use, and natural features such as
water bodies or wooded areas, roads and property boundaries within 500 feet
of the tract. This information may be presented on an aerial photograph at a
scale of no less than 1 inch: 400 feet.
5. A Management Plan for the restoration and long-term care of open space
areas and agricultural lands in perpetuity if applicable.
Section 18: 18.81(1) change relating to what constitutes receiving bonus parcels:
1. The development yield analysis in section 18:31(3)(l) shall establish the base
development yield for the parcel.
The base development density may be increased at Planning Commission and
Common Council discretion that the overall layout fits with the proposed
theme and spirit of the ordinance, to the allowed number of bonus parcels
per Sub. 2 below, if the development demonstrates it is adequately applying
some of some of the following guidelines in some way. Reasons for allowing
any bonus parcels shall be stipulated in City approving
resolutions/ordinances, as bonus lots are not guaranteed.
i. Providing for access by the general public to trails, parks, or other recreational
facilities.
ii. When practical, reusing existing buildings and structures which incorporate
rural or agrarian themes, including but not limited to those sites inventoried by
the State Historical Society of Wisconsin.

Plan and any other significant environmental features found in the platted
area. Preservation may include a minimum 50-75 foot setback from the
environmental features identified.
iv. Restores native prairie and provides a management plan for perpetual
maintenance.
v. Improves water quality through stormwater management standards and practices,
that exceed the minimum standards of Chapter 34 of the Municipal Code, and, as
approved by the City Engineer and the Public Works Committee.
vi. Restores or enhances the functional classification of wetlands using techniques
approved by the USDA-NRCS, Wisconsin Department of Natural Resources, or
the Conservation Coordinator. Enhancement techniques may be performed by
third parties (i.e. City, DNR, etc.).
vii. Provides more than the required 50% of the gross acreage as open space in the
development (Rights-of-way shall not count towards open space requirements.
Stormwater outlots may count towards open space requirements, subject to
Planning Commission discretion/approval, when they are subject to deed
restrictions, easements or open space management plans.).
viii. Provides for preserving larger tracts of agricultural workable land in perpetuity
and provides a management plan for perpetual maintenance.
ix. As opposed to wetlands or other non-buildable areas; Open, buildable land
may be counted as more meaningful preservation for purposes of awarding
bonus lots.
Section 18: 18.81(2) change:
For parcels less than forty (40) eighty (80) acres in area, the maximum bonus permitted is the
greater of three (3) four (4) parcels or 15% of the base development density. For parcels
between forty (40) and eighty (80) acres in area, the maximum bonus permitted is five (5)
parcels. For parcels eighty (80) acres or greater in area, the maximum bonus permitted is the
greater of six (6)four (4) parcels or 20% of the base development density. All development yield
bonuses shall be calculated to the nearest one-hundredth. In cases where the total combined
development yield bonus results in a fraction, all such fractions shall be rounded up to the next
whole number. All parcels shown in a developer’s yield analysis must demonstrate that each
parcel could actually be developed on the site proposed. Thus, each yield parcel must show that
adequate water, sewer, stormwater management, and buildable area is present and attainable to
the Planning Commission.
The base development density for an EA Exclusive Agriculture or A Agricultural zoned lot is
based upon a rate of at least 120,000 square feet per lot (300 feet in width). The base development
density for any other piece of land is based on the existing minimum zoning requirements OR the
minimum Comprehensive Plan density requirements, whichever is stricter. All parcels shown in a
developer’s yield analysis must demonstrate that each parcel could actually be developed on the
site proposed. Thus, each yield parcel must show that adequate water, sewer, stormwater
management, and buildable area are present and attainable to the Planning Commission.
