Section 4.05
Intent. The intent of the Manufactured Housing District (MH) is to provide an affordable housing alternative where placement of such a development would be appropriate and consistent with the general character of the Village. The standards required in this district are intended to be consistent with the adopted standards for other types of housing in the Village of Mayville. In addition to the standards of this Ordinance, all manufactured housing communities shall comply with Act No. 96 of Public Acts of 1987 as amended, being R 125.2301 et seq. of the Michigan Compiled Laws Annotated (MCLA). However, some standards of this Ordinance are more stringent than the typical standards promoted by the Michigan Manufactured Housing Commission. These more stringent standards reflect the overall nature of the Village of Mayville, in contrast with some other areas of Michigan where the universal rules of the Michigan Manufactured Housing Commission may be appropriate. These adopted standards are designed to foster and encourage development which complements and protects the investment on adjacent properties and promotes preservation of important natural features. This ordinance is to make clear the requirements for bringing new or used manufactured homes into the Village of Mayville.
Since the characteristics, densities, and impacts of a manufactured housing community 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 communities are not necessarily considered to be completely compatible with other types of single-family neighborhoods. Therefore, manufactured housing communities may serve as a
transitional use between Residential and Non-Residential Districts, similar to the manner and fashion in which multiple-family districts are to be utilized.
Preliminary Plan Development Standards. Manufactured housing communities shall be subject to the review and approval of a preliminary site plan by the Planning Commission. The site plan shall consist of a manufactured housing community preliminary plan, as described in the Section 11 of the Manufactured Home Act, Act No. 96 of Public Acts of 1987, as amended. Such review of the preliminary site plan is required in order to minimize the possibility of adverse effects upon adjacent property; and furthermore 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.
Design Standards for Overall Development
Maximum Age. Manufactured housing units shall be no older than 3 years at the time of installation.
Minimum Development Size. Manufactured housing communities shall be at least fifteen (15) acres in area, excluding adjacent parcels which may be proposed for expansion.
Access. The main entrance to the development shall have access to a public thoroughfare or shall be connected to an asphalt or concrete collector or arterial road by a hard-surfaced road in a permanent easement which shall be recorded by the developers. Sole access to the development via an alley is prohibited. Entranceway structures, including but not limited to, walls, columns, and gates marking the entrance to a manufactured housing community, may be permitted, and may be located in a required yard, except as provided in this Article. Such entranceway structures shall be subject to the requirements of Section 8.17., Intersection Visibility, to permit unobstructed access by all emergency equipment, and such allowance for “clear vision” shall otherwise comply with all codes and ordinances of the Village and Tuscola County. Sight distance from points of ingress and egress shall be approved by the Tuscola County Road Commission. The structure location shall also be approved by the Village.
Perimeter Setbacks. Manufactured homes shall be set back at least fifty (50) feet from any public street right-of-way line and ten (10) feet from any other exterior property line. This setback shall include a minimum twenty (20) foot wide greenbelt, which includes minimum screening, as outlined below.
Landscape and Screening. A landscape and screening plan shall be incorporated in the plans submitted for preliminary site plan review to the Planning Commission. The plan shall indicate the type and size of landscape planting and screening improvements to be completed in the proposed manufactured housing community. Manufactured housing communities shall be landscaped and screened as follows: 1) Ground Surfaces. Exposed ground surfaces in all parts of the manufactured housing community shall be paved or covered with stone or other solid
material or protected with grass, trees, or shrubs that are capable of preventing soil erosion. The ground surface in all parts of every manufactured housing community shall be graded and equipped to drain all surface water in a safe, efficient manner. 2) Perimeter Screening. All manufactured housing communities shall be screened from an abutting a public right-of-way and existing adjacent residences. The required screening shall consist of evergreen trees or shrubs at least three (3) feet in height, which are spaced so they provide a continuous screen at maturity. Alternative screening devices may be utilized if they conceal the manufactured home development as effectively as the required landscaping described above. 3) Right-of-Way Greenbelt. A landscaped berm measuring two and one-half (2 1/2) to three (3) feet in height shall be constructed along the public roads on which the manufactured housing community fronts. The berm shall be constructed with slopes no steeper than one (1) foot vertical rise for each four (4) feet horizontal run. A minimum of one (1) deciduous shade tree, one (1) evergreen tree and four (4) shrubs shall be planted for each thirty (30) lineal feet, or portion thereof, of required greenbelt length. At time of planting, canopy trees shall have a minimum size of three (3) inch caliper and evergreen trees shall have a minimum height of six (6) feet. Trees may be planted at uniform intervals, at random, or in groupings. All existing trees four (4) inches or greater in diameter (dbh) within the greenbelt shall be preserved, except where their removal is necessary to install access points. 4) Site Landscaping. A minimum of one (1) deciduous or evergreen tree shall be planted per two (2) manufactured home sites. 5) Parking Lot Landscaping. Off-street parking lots containing more than fifteen (15) spaces shall be provided with at least ten (10) square feet of interior parking lot landscaping per space. Such areas shall measure at least one hundred fifty (150) square feet and shall be covered by grass, ground cover, shrubs, or other live plant material. At least one (1) deciduous tree shall be planted per parking lot landscaped area. 6) Perpetual Maintenance. Dead, damaged, and/or diseased screening shall be replaced, within a reasonable time frame, so as to maintain the approved and/or allowed screening technique originally put in place. 7) Required Open Space. For developments with fifty (50) or more sites, a minimum of two percent (2%) of the development’s gross acreage shall be dedicated to well drained, useable open space. A minimum of twenty-five thousand (25,000) square feet of open space shall be provided. Open space shall be maintained by the manufactured housing community management and shall be relatively accessible to all areas of the development. 5. Streets
Street Layout. Maximum cul-de-sac length shall be one thousand (1000) feet. A dead-end road shall terminate with a fifty (50) foot in diameter cul-de-sac; a blunt- end road is prohibited. Adequate sight distance shall be provided at all intersections, in accordance with clear vision standards applicable to all areas of the Village of Mayville.

Storage. If the owner of the manufactured housing community shall permit storage of boats, motorcycles, recreation vehicles, and similar equipment in the manufactured housing community, common areas for the storage of that equipment shall be provided by the owner within the development. Such storage shall be limited to use only by residents of the manufactured housing community. If proposed, the location of such storage areas shall be shown on the preliminary site plan. No part of any such storage area shall be located in a required yard on the perimeter of the manufactured housing community. Such storage area shall be screened from view from existing residences adjacent to the manufactured housing community, in accordance with the perimeter screening provisions described above. Manufactured housing community owners who prohibit storage of boats, off-the-road motorcycles, recreation vehicles, and similar equipment are not required to construct common areas for storage.
Drainage. The manufactured housing community shall provide sufficient stormwater facilities, independent of sanitary sewers, to prevent flooding of streets, lot, or recreation areas. On-site stormwater detention facilities, if provided, may be required to be fenced for safety reasons. The street drainage system shall be designed in such a
way so as to minimize ponding and icing conditions. All stormwater drainage improvements shall be subject to review and approval by the Tuscola County Drain Commissioner, and the MDEQ, in accordance with MDEQ Manufactured Home Park Standards, pursuant to 1987 P.A. 96, as amended.
