(A) Intent. The intent of this section is to provide an affordable housing alternative that is consistent with the general character of the city. In addition to the standards of this chapter, all manufactured housing developments shall comply with Act No. 96 of Public Acts of the State of Michigan of 1987 as amended. Some standards of this chapter are more stringent than the typical standards promoted by the Michigan Manufactured Housing Commission. These adopted standards are designed to foster and encourage development which:
(1) Locates communities in appropriate areas to complement specific needs;
(2) Compliments and protects the investment on adjacent properties; and
(3) Promotes preservation of important natural features.
Since the characteristics, densities and impacts of a manufactured housing development typically simulate those of multiple-family residential developments, and because they typically are served by private streets and utility systems which intercept the local street and utility systems, manufactured housing parks are not necessarily considered to be completely compatible with other types of residential neighborhoods. Therefore, manufactured housing development are intended to serve as a transitional use between residential and nonresidential districts and shall be restricted to M-1 Light Industrial Districts whereby the parcel is not isolated on more than three sides by the M-1 District.
(B) Principal uses permitted. No building, structure or land shall be used, and no building or structure shall be erected, except for one or more of the following specified uses unless otherwise provided in this chapter.
(1) Manufactured housing developments, which conform to the requirements of this section, and the Department of Housing and Urban Development (HUD) standards, or A.N.S.I standards.
(2) Community accessory uses, building and structures including one management office building, utility/laundry buildings, auxiliary storage space for manufactured housing development tenants, community buildings for use by the tenants, recreation areas, playgrounds and recycling stations. All such accessory uses and structures shall meet the standards provided in this chapter.
(3) State licensed adult and child care facilities in a manufactured home, which are permitted in the single-family zoning districts, subject to the approval of the development management.
(4) Accessory structures on manufactured home sites including decks, private garages, carports and enclosed or screened storage areas which meet the standards of this subchapter and the rules and regulations promulgated by the Michigan Manufactured Housing Commission, or its successor.
(5) The business of selling new or used manufactured homes in the development that are to remain on-site may be sold by the resident, owner or a licensed dealer or broker, provided the manufactured housing development management permits the sale.
(6) All electrical, telephone, cable TV and gas lines, located within the development, as an available service in the park, shall be placed underground, and shall be subject to the other related definition and use provisions of this chapter.
(7) Uses not specifically noted above are prohibited as permitted principal uses.
(C) Required conditions. Manufactured housing developments shall be subject to the review and approval of a site plan by the Planning Commission. The site plan shall consist of a manufactured housing development preliminary plan, as described in Section 11 of the Mobile Home Act, Act No. 96 of Public Acts of 1987, as amended. Such review of the site plan is required in order to minimize the possibility of adverse effects upon adjacent property and to find proper relationships in the development features as they relate to traffic safety, service roads, driveways, parking areas accessory buildings and uses, and planned open space.
(D) Special land use.
(1) Schools, school-related facilities, religious institutions, temples, and similar places of worship, connected with the operation of a licensed manufactured housing development or similar uses not included in this paragraph.
(2) Adult and child care facilities in a manufactured home or community building which are listed as special condition uses in the R-1A, R-1B and R-1C One-Family Zoning Districts, subject to the approval of the development management.
(3) Golf courses.
(E) Design standards for overall development.
(1) Minimum development size. A manufactured housing development shall be at least five acres in area, excluding adjacent parcels that may be proposed for expansion.
(2) Access.
(a) The main entrance to a development shall have access to a public thoroughfare. Access to the development via an alley is prohibited.
(b) Entranceway structures, including but not limited to, walls, columns and gates marking the entrance to a manufactured housing development, may be permitted, and may be located in a required yard, except as provided in this section.

(3) Perimeter setback. Manufactured homes shall be set back at least 50 feet from any public street right-of-way line. The setback shall include a minimum 20 foot wide greenbelt, which includes landscape and screening features as described below.
(4) Landscaping, screening and ground cover. A landscape and screening plan shall be incorporated in the preliminary plans submitted for site plan review to the Planning Commission. The plan shall indicate the type and size of landscape planting and screening improvements to be completed. A manufactured housing development shall be landscaped and screened as follows:

(g) Landscaped berms measuring two and one-half feet in height may be required by the Planning Commission to be constructed along public roads. The berm shall be constructed with slopes no steeper than one foot vertical rise for each four feet horizontal run. Landscaping adjacent to the road shall comply with the requirements in Table 6-1 below.
