any proposed use if identified as being environmentally sensitive.
Areas identified as being environmentally sensitive include, but are
not limited to:
A.
All areas mapped as floodplain by the Federal Emergency Management
Agency (FEMA), Wisconsin Department of Natural Resources, or other
public or private entity.
B.
All wetlands as defined in § NR 103.02(5), Wis. Adm. Code,
including any applicable DNR wetland setbacks/offsets. Also, the City
of Muskego's wetland protection offsets identified in the Zoning Code
to serve as a protection buffer.

E.
Areas that are known to provide habitat for rare, threatened or endangered
species.
F.
Burial sites and Indian mounds.
G.
Drainageways that contain running water during spring runoff, during
storm events or when it rains. A twenty-five-foot buffer from the
edge of the drainageway shall be included. Areas determined to be
environmentally sensitive may be included as common open space in
a conservation subdivision but shall not be included in the development
yield analysis. These lands shall be identified as an outlot or other
designation that indicates the land is not available for development.
The number of residential units for a parcel shall be determined in accordance with § 400-133F(3), Density and density bonuses, of Chapter 400, Zoning, of the City Code.
A.
General consideration. The Plan Commission shall have the ability
to specify which areas shall be preserved.
B.
Agricultural use. If agricultural uses are proposed to be maintained,
lots shall be configured in a manner that maximizes the usable area
remaining for such agricultural uses, with appropriate buffers between
agricultural uses and residential structures.
C.
Residential lot requirements. Residential parcels located within
conservation subdivisions shall conform to the CPD Conservation Planned
District zoning regulations respectively and the following:
(2)
All lots and dwellings shall be grouped into clusters of no more
than 20 dwelling units. Said clusters shall:
(a)
Be located to minimize negative impacts on the natural, scenic,
and cultural resources of the site and minimize conflicts between
incompatible uses.
(b)
Avoid encroaching on rare plant communities, high-quality environmental
resources, or endangered resources as may be identified by the Wisconsin
Department of Natural Resources.
(3)
Lots shall be configured to minimize the amount of road length required
for the subdivision.
(4)
Lots shall be configured away from wetlands to minimize the amount
of possible runoff and impacts on these environmental lands.
(5)
All lots shall abut open space on at least one side. A minor street
may separate lots from said open space.
D.
Open space standards. Open space shall be designated as part of the
development.
(1)
The minimum required open space is 50% of the gross acreage. Rights-of-way
shall not count towards open space requirements. Stormwater outlots
may count towards open space requirements, subject to Plan Commission
approval, when they are subject to deed restrictions, easements, or
open space management plans.
(2)
All open space shall be owned and maintained under one of the alternatives listed in Subsection E and as approved by the City.
(3)
The uses within the open space shall be accessible to the residents of the development. These uses may also be available to the general public provided the proper approvals are received. The required open space shall be undivided and restricted in perpetuity from future development, as specified in Subsection E.
(4)
That portion of open space designed to provide plant and animal habitat
shall be kept as intact as possible. Trails shall be designed to avoid
fragmenting these areas.
(5)
Accessible open space in upland areas shall be available for recreational
uses such as trails, play fields, or community gardens but should
be designed in a manner that avoids adversely impacting archaeological
sites.
(6)
A pathway system connecting open space areas accessible to neighborhood
residents and connecting these areas to neighborhood streets and to
planned or developed trails on adjacent parcels shall be identified
in the plan.
(7)
The following areas or structures may be located within the open
space area and shall be counted toward the overall open space percentage
required:
E.
Ownership and maintenance of common areas. The designated common open space and common facilities may be owned and managed by one or a combination of the following below. It should be noted that common areas may be mandated as per § 392-34 of this chapter.
(1)
An incorporated homeowners' association. Membership in the association
is mandatory for all purchasers of homes in the development and their
successors. The homeowners' association bylaws, guaranteeing continuing
maintenance of the open space and other common facilities, and the
declaration of covenants, conditions and restrictions of the homeowners'
association shall be submitted for approval to the City as part of
the information required for the preliminary plat.
(2)
A condominium association established in accordance with the Condominium
Ownership Act, Ch. 703, Wis. Stats. If the common open space and facilities
are to be held under the Condominium Ownership Act, Ch. 703, Wis.
Stats., the condominium instruments shall identify the restrictions
placed upon the use and enjoyment of the common open space. All common
open space shall be held as a "common element" as defined in § 703.02(2),
Wis. Stats.
(3)
A nonprofit conservation organization. If the common open space is
to be held by a nonprofit conservation organization, the organization
must be acceptable to the City of Muskego. The conveyance to the nonprofit
conservation organization must contain appropriate provisions for
reversion in the event that the organization becomes unwilling or
unable to uphold the terms of the conveyance.
(4)
The City of Muskego or another governmental body empowered to hold
an interest in real property. The City may accept the common open
space provided the common open space is accessible to the public and
provided the City agrees to and has access to maintain the common
open space.
(5)
An individual who will use the land for open space purposes as provided
by a conservation easement.
