[Ord. No. 210, effective 9-25-1994]
The regulations concerning multiple-family districts provide for a variety of single-family and multiple-family residential land uses. This district is intended to meet the housing needs of people who choose to live in residential areas with higher density than single-family districts, generally in multiple-family attached units. This district also provides for a limited range of other uses that are considered necessary or appropriate to enhance the quality of life within Grosse Ile's multiple-family residential neighborhoods. Specifically, the regulations set forth herein are intended to provide for the following:
A. 
Common types of housing include various forms of multiple-family residential units and single-family residential units.
B. 
The allocation of land for multiple-family residential uses shall be based on the determination of need, the availability and adequacy of public facilities and services, and compatibility with the environment and surrounding uses. Multiple-family residential districts, in some cases, can be used to provide a transition between nonresidential districts and nearby single-family residential districts.
C. 
Multiple-family uses are classified into two districts. The R-2 Multiple-Family Residential District permits attached dwelling units in settings characterized by abundant open space, at a density, as defined in Article 1, of up to 5.8 units per acre, subject to site conditions and all ordinance standards. The R-3 Multiple-Family Residential District permits attached dwelling units at a density, as defined in Article 1, of up to 8.7 units per acre, subject to site conditions and all ordinance standards. This provides the opportunity for development of more affordable housing and meet the needs of individuals and families needing less space that is compatible with the predominant surrounding single-family development.
In multiple-family residential districts, no building shall be erected and no building or land shall be used except for the following uses, unless otherwise permitted in this chapter, or by state or federal law, subject to the standards and requirements set forth herein:
A.

(2) 
Multiple-family dwelling units. Multiple-family units which are reached off of a common stair landing or entryway are only permitted in the R-3 District.

Notes pertaining to development regulations:
1
Density shall be calculated as the number of dwelling units situated on or to be developed per net acre of land. For purposes of calculating maximum density, only 25% of the acreage determined to be wetlands protected by the Goemaere-Anderson Wetland Protection Act, PA 203 of 1979, as amended, or the Township of Grosse Ile, shall be calculated toward the total site acreage. All open bodies of water, land within the one-hundred-year floodplain, public rights-of-way and areas within overhead utility line easements are excluded from calculation.
2
All units shall have at least one living room, one bedroom, kitchen facilities, a storage closet and sanitary facilities.
3
Every newly created lot must have a sufficient building envelope, exclusive of any regulated wetlands, to meet required zoning district setbacks, greenbelt buffers, off-street parking requirements and accessory uses as specified in this chapter.
4
The minimum side yard shall be increased by one foot for each 10 feet or part thereof by which the length of the multiple-family building facing the side lot line exceeds 30 feet.
5
The minimum side yard on a side facing a street shall not be less than the required minimum front yard setback.
6
Setback from internal road shall be 25 feet or the height of the building whichever is greater.
7
Parking lot setbacks are measured from the edge of a common parking lot, utilized for the parking of more than two vehicles, to the nearest line of the building. Parking lot setbacks do not apply to driveway approaches entering garages.
8
For multiple-family developments where there are two or more buildings on the same parcel, the minimum required distance between two buildings shall be 30 feet or the combined height of the two buildings, whichever is greater.
9
Natural feature setback shall be maintained in relation to the ordinary high-water mark of any pond, river or channel, and to the edge of any drainageway or regulated wetland. Only waterfront structures and appurtenances, as permitted in Article 17, Waterfront Provisions, may be located within the natural feature setback. This setback may be reduced by Planning Commission approval upon a determination that it is clearly in the public interest. In determining whether the setback reduction is in the public interest, the benefit which would reasonably be expected to accrue from the proposed development shall be balanced against the reasonably foreseeable detriments to the natural feature. The following general criteria shall be applied in undertaking this balancing test:
a.
The relative extent of the public and private need for the proposed activity.
b.
The availability of feasible and prudent alternative locations and methods to accomplish the expected benefits from the activity, including alternatives which are off-site or on other commercially available properties.
c.
The extent and permanence of the beneficial or detrimental effects which the proposed activity may have on the public and private use to which the area is suited, including the benefits the wetland provides.
d.
The probable impact of the proposal in relation to the cumulative effect created by other existing and anticipated activities in the watershed.
e.
The probable impact on recognized historic, cultural, scenic, ecological, or recreational values and on the public health or fish or wildlife.
f.
The size and quality of the wetland.
g.
Proximity to any waterway.
h.
Extent to which upland soil erosion adjacent to protected wetlands or drainageways is controlled.
i.
Economic value, both public and private, of the proposed land change to the general area.
j.
Findings of necessity for the proposed project which have been made by other state or local agencies.
