Grouping of residences in cluster or conservation subdivisions will permit individual minimum lot sizes to be reduced provided that overall density within the subdivision is maintained. The remaining undeveloped area within the subdivision is to be used to protect natural resources, provide common open space and preserve the scenic qualities of the City. Grouping of residences facilitates potential for shorter road lengths and other infrastructure efficiencies.
Cluster or conservation subdivisions shall be submitted for review and follow the provisions of this chapter in the same manner as any other subdivision. In addition the following also apply:
A. 
Proposed cluster or conservation developments shall include a minimum of five acres and shall be platted according to the requirements of this chapter.
B. 
The maximum permitted number of lots in such development shall be determined by dividing the total area of the subdivision, excluding streets, by the minimum lot sizes required by the City Zoning Ordinance. In condominiums and similar developments, under which no new lots are created, the term "maximum number of dwelling units" shall substitute for the term "maximum number of lots" in the preceding statement in determining overall density.
C. 
Lots shall be located so that:
(1) 
They are grouped together to form clusters and surrounded by open space.
(2) 
Negative impacts to natural resources and environmentally sensitive areas are minimized, including wetlands, floodplains, drainageways, woodlands, and slopes over 12%.
(3) 
Negative impacts to historic and cultural resources are minimized.
(4) 
Negative impacts to prime agricultural land and large tracts of productive farmland are minimized. The location of lots should avoid interference with normal agricultural practices.
(5) 
Views of open space and natural resources are maximized. Lots should be hidden behind woodlands, hedgerows, and topography when possible. Lots should not be located in prominent, visible places like hilltops and ridgelines.
D. 
Open space shall:
(1) 
Surround clusters of residential lots and provide a buffer between cluster groups.
(2) 
Be interconnected to other open space both within the plat and beyond. Open space should not be isolated and disconnected.
(3) 
Include natural resources, environmentally sensitive areas, and productive agricultural land (when the intent is to preserve the agricultural use) to the greatest extent possible.
(4) 
Include all excess land not used for lots and streets.
E. 
Ownership of open space. Open space shall be dedicated and restricted as such on the plat and conveyed in common to each of the owners of lots in the development or dedicated to the City. The City shall not be required to accept dedication. Lands dedicated to the public must be accepted by appropriate action of the governing body of the accepting unit of government. If the land is to be conveyed to owners of lots in the development, a homeowners' association or similar legally constituted body shall be created to maintain the open space land.
F. 
Maintenance and operation of common open space and facilities. A plan and narrative for the use, maintenance, and insurance of all common facilities, including provisions for funding, shall be provided to and approved by the Common Council prior to final plat or condominium plat approval.
G. 
Any restriction placed on platted land by covenant, grant of easement or any other manner which was required by a public body or which names a public body as grantee, promisee or beneficiary shall vest in the public body the right to enforce the restriction at law or in equity against anyone who has or acquires an interest in the land subject to the restriction.
H. 
Water supply and sewage disposal shall meet the minimum standards of Chs. SPS 383 and 385, Wis. Adm. Code, the County Sanitary Ordinance and other applicable regulations.
