To provide for a diversity in housing types and prices.
E. 
To encourage mobile home developments that are beneficial rather than detrimental to property values and the general welfare of the area in which they are proposed.

The total number of lots in a mobile home development shall not exceed a maximum of five lots per acre of developable area.
A. 
Minimum tract area. The minimum tract area for a mobile home development shall be 15 acres. Mobile homes may be grouped in a mobile home development, provided they meet all the requirements of Article XIV (Mobile Home Development District) of this chapter and all regulations specified in Article VI, § 198-47 (minimum design standards for mobile home parks), of Chapter 198, Subdivision and Land Development, and all other applicable regulations.
B. 
Setback from tract boundary. No mobile home or other building may be located closer than 40 feet to any boundary of a mobile home development regardless of whether that boundary abuts a lot, water body, road or other right-of-way. In the event a mobile home development abuts another such development, this may be reduced to 25 feet.
C. 
Setback from streets. In no case shall the long side of a mobile home, or any side of another primary building or accessory use, be located closer than 25 feet to the ultimate right-of-way line of any public street, or the equivalent right-of-way line of private interior roadways within a mobile home development; provided, however, that the short side of a mobile home may be located no closer to these facilities than 20 feet. No more than four homes in a row shall have the same setback; where varied setbacks are utilized the difference shall be at least four feet.
D. 
Setback from common parking facilities. No mobile home or accessory use shall be located within 25 feet of any common parking area.
E. 
Lot size. All mobile home lots in a mobile home development shall have a minimum lot size of 5,000 square feet, and a contiguous buildable lot area of not less than 2,000 square feet.
[Amended 9-16-1998 by Ord. No. 1147]
F. 
Lot width and depth. No individual mobile home lot shall be less than 55 feet in width at the building setback line. No individual mobile home lot shall be less than 25 feet in width at the right-of-way line of a public street or equivalent right-of-way line or the edge of the pavement of a private street, as applicable. No individual mobile home lot shall have a minimum depth of less than 70 feet.
G. 
Side and rear setbacks. No mobile home, accessory building or accessory structure may be located closer than four feet to any side or rear lot line of an individual mobile home lot, provided, however, that all minimum requirements of Subsection I must be met, and provided further that accessory buildings may be located on the lot line if physically joined to each other with a common wall located on the property line.
H. 
Unit location on individual lots. Mobile homes placed on individual lots should, wherever practicable, utilize the minimum setbacks specified in Subsection G and be located off center on the lot so as to provide a large usable open yard space and outdoor living area in one section of the lot.
I. 
Distance between structures. Mobile homes and structures, buildings or roofed areas attached thereto, shall be separated from each other, and from other buildings and structures, other than accessory buildings and structures, at their closest points by a minimum of 20 feet, provided, however, that whenever two mobile homes have their longer sides parallel or essentially parallel to each other for more than 25% of the length of either, the minimum distance between the two mobile homes shall be 30 feet. The sides shall be considered essentially parallel if they form an angle of less than 45° when extended to intersect.
J. 
Lot coverage. The maximum coverage of any individual mobile home lot by all primary and accessory buildings and structures, including covered patios or decks, shall be no greater than 35%.

M. 
Design alternative. In order to allow clustering of lots designed to encourage flexibility in site design, preservation of natural features, and to maximize creation of accessibility of recreation areas, distance between structures, minimum lot width and minimum lot size may be reduced up to a maximum of 10% upon approval of the Township Council, provided at least 50% of all lots so reduced shall directly abut a part of the common open space for a distance of at least 20 feet. An area equal to that by which each lot is reduced shall be added to the minimum common open space specified in § 230-81. All other regulations remain as stated herein.
At least 10% of the area set aside for common open space should be centrally located, accessible to everyone and suitable for active recreational or other purposes.
Special common parking areas must be provided for such vehicles as trailers, boats, campers, and trucks (other than small pickup trucks). A minimum of one supplemental parking space must be provided for each 10 mobile home lots. The supplemental parking area shall be screened with plant material as approved by Council, from view of a street or a mobile home lot.
Storage areas, enclosed in a building in conjunction with the mobile home development maintenance facilities, should be made available for use of the mobile home development residents in addition to on-lot storage permitted in § 230-78C(2). A minimum of one storage area of 200 square feet shall be provided for each 10 mobile home lots.
