A. 
Purpose. This section is intended to carry out the provisions of Act 177, PA 2001, as amended (now MCL § 125.286h), to include an open space preservation development option in the Pittsfield Township Zoning Chapter. This section proposes to accomplish this purpose by allowing the owner of certain parcels of land the option to develop that land in a manner that groups dwelling units on portions of the land that are most suitable for residential development while requiring the remaining portions of land most suitable for open space use to be perpetually preserved as undeveloped open space. The regulations in this section are also intended to accomplish the following nonexclusive list of purposes.
(1) 
Preserve natural drainage systems, open space, farmlands, rural character, woodlands and wetlands, natural topography, and environmentally sensitive areas.
(2) 
Achieve a higher quality of residential development than could otherwise be achieved under conventional zoning.
(3) 
Permit development that is consistent with the Township's adopted Master Plan and any other applicable adopted plans.
(4) 
Preserve natural vegetation to the extent feasible.
(5) 
Preserve open space.
(6) 
Facilitate the construction and maintenance of streets, utilities, and public services in a more economical, efficient, and environmentally friendly manner to reduce capital costs of development.
(7) 
Limit soil erosion potential by reducing the amount of clearing and grading needed for development.
(8) 
Encourage a less sprawling form of development, thus preserving open space as undeveloped land.
(9) 
Allow for design innovation to provide flexibility for land development where the normal development approach would otherwise be unnecessarily restrictive or contrary to other Township goals.
B. 
Review authority. The Pittsfield Township Planning Commission shall have authority to approve or deny applications for an OSPDO that is to be developed as a site condominium or a metes and bounds land division. The Township Board shall have authority to approve or deny an application for an OSPDO that is to be developed as a subdivision, after recommendation by the Planning Commission. The Township Board shall have final authority to approve or reject the conservation easement and master deed or restrictive covenants for a development under this section.
C. 
Eligible property.
(1) 
A parcel of land, which parcel shall be the parent lot for the purposes of this section, is eligible for an OSPDO if all the following requirements are met.
(a) 
The parent lot is zoned AG, R-1A, R-1B, R-2, or R-3.
(b) 
The parent lot has an area of at least three acres of contiguous land, not divided by a road.
(c) 
The parent lot is under single ownership control such that a single person or entity has proprietary responsibility for completing and maintaining the development. An applicant applying for an OSPDO under this section shall provide documentation of such ownership or control in the form of agreements, contracts, deeds, or other such evidence as is acceptable to the approving authority to assure that the applicant has sufficient ownership interest in the parcel to bind the land and assure that the development will be completed in its entirety as approved and that the land will continue to be in compliance and maintained in accordance with the final site plan, preliminary plat as finally approved, and the approved maintenance plan under this section.
(2) 
A OSPDO development shall maintain a minimum of 30% of the gross area of the site as dedicated open space held in common ownership.
(3) 
Open space preservation developments achieving at least 50% dedicated open space and meeting the provisions of § 40-7.02I shall be treated as a permitted land use. Open space preservation developments with between 30% and less than 50% dedicated open space but otherwise meeting the provisions of § 40-7.02I shall be treated as a conditional land use.
D. 
Permitted uses. The following uses are permitted within an OSPDO:
(1) 
AG District. In an AG Zoning District, the land may be used for single-family detached dwelling units and accessory buildings or structures on an approved lot or condominium unit. All other uses listed in § 40-4.20 shall be permitted in the dedicated open space, except that intensive livestock or poultry raising operations, such as poultry houses, hog hotels, etc., shall not be permitted.
(2) 
R-1A, R-1B, R-2, or R-3 District. All residential uses and types permitted in § 40-4.20 in a R-1A, R-1B, R-2, and R-3 Zoning Districts, are permitted in an OSPDO under this section.
E.

Sites not served by public utilities.
(a) 
For sites not served by public utilities, the number of units shall not exceed the area of the parent lot, in acres, multiplied by:
[1] 
0.35 for land zoned AG.
[2] 
0.80 for land zoned AG that is designated for rural residential, low-density use in the Township's adopted Comprehensive Plan.
[3] 
1.0 for land zoned R-1A.
[4] 
1.25 for land zoned R-1B.
(b) 
The minimum area of each lot or site condominium unit in an OSPDO shall not be less than the minimum area required by Washtenaw County for well and septic tank/drainfield permits.
(2) 
For lots served by public utilities, the number of dwelling units permitted shall not exceed the number of dwelling units customarily developable in the zoning district in which the proposed development is located, developed with a conventional layout and all applicable ordinances and laws observed. In order to calculate density with a conventional subdivision or site condominium layout, the applicant shall submit a concept site plan of the property with a conventional layout. The plan shall indicate the topography of the site at two-foot contour intervals and the limits of all floodplains, water bodies, wetlands, easements, and other areas which would be set aside and preserved due to impracticality, economic infeasibility, contractual prohibition, or based upon applicable law or ordinance. In addition, the concept plan with the conventional layout shall include the general street pattern and lot configurations. In general, the plan shall be drawn with sufficient detail to permit the Planning Commission to determine the density that would be achieved by conventional development.
(3) 
The area of the parent lot shall be as defined in the definition of lot area in Article II, herein.
(4) 
To encourage the use of the OSPDO, if all standards set forth in § 40-7.02I are met, the underlying density established by § 40-7.04E(1) and (2) may be increased by up to 20% at the discretion of the Planning Commission. Density bonuses shall be based upon a demonstration by the applicant of at least two of the following:
(a) 
Preservation of significant natural features. Preservation of significant natural features contained on the site, as long as it is in the best interest of the Township to preserve the natural features that might be negatively impacted by conventional residential development. The determination of whether the site has significant natural features shall be made by the Planning Commission, after review of a natural features analysis, prepared by the applicant, that inventories these features; or
(b) 
Provision of recreation facilities. If the site lacks significant natural features, it can qualify with the provision of usable recreation facilities to which residents and nonresidents of the development shall have reasonable access. Such recreation facilities include areas such as nonmotorized mobility improvements, neighborhood park, passive recreational facilities, soccer fields, ball fields, bike paths, or similar facilities that provide a feature of community-wide significance and enhance residential development; or
(c)
