5.   Required Development Standards:

   A.   The land area of a manufactured home park shall not be less than 80,000 square feet.

   B.   Manufactured home sites shall be at least 4,500 square feet in area.

   C.   Each manufactured home within such park shall contain a flush toilet, sleeping accommodations, a tub or shower bath, kitchen facilities, and plumbing and electrical connections designed for attachment to appropriate external systems and so attached.

   D.   Each manufactured home site shall have side yards with each yard having a width of not less than 10 feet.

   E.   Each manufactured home site shall have front and rear yards with the rear yard not less than 25 feet in depth and the front yard of not less than 35 feet. Corner manufactured home sites shall have front yard setbacks on each street frontage.

   F.   For the purpose of this section, yard width shall be determined by measurement from the manufactured home face (side) to its manufactured home site boundary from which every point shall not be less than the minimum width herein provided. The rear yard shall be the yard opposite and having the farthest distance as measured from the street or public way.

   G.   From all lots, a minimum distance of 35 feet shall be maintained from the boundary of the manufactured home park.

   H.   A manufactured home shall not be permitted to occupy single or multiple sites if either its length or width would cause it to occupy the space required by yard setback dimensions.

   I.   Each manufactured home site shall be provided with a stand consisting of reinforced concrete runways not less than four inches thick and not less than the length of the manufactured home that will use the site. These runways will be so constructed, graded and placed to be durable and adequate for support of the maximum anticipated load during all seasons.

   J.   Each manufactured home shall be anchored to the ground as provided in Chapters 103A.30-103A.33 of the Code of Iowa.

   K.   Accessory structures may be no closer to the side lot line than five feet.

   L.   A permanent type material and construction compatible with the design and color of the manufactured home shall be installed to enclose the open space between the bottom of the manufactured home floor and the grade level of the manufactured home stand, and shall be constructed to provide substantial resistance to heavy winds. Skirting shall be maintained in an attractive manner consistent with the exterior of the manufactured home and to preserve the appearance of the manufactured home park. Sufficient screened ventilating areas shall be installed in the skirting to supply the combustion requirements of heating units and ventilating of the manufactured home. Provisions shall be made for easy removal of a section large enough to permit access for inspection of the enclosed area under the manufactured home, and for repair of sewer and water riser connections.

   M.   All manufactured homes within such park shall be suitably connected to common sewer and water services provided at each manufactured home site. All sanitary sewer facilities, including plumbing connections to each manufactured home site, shall be constructed so that all facilities and lines are protected from freezing, from bumping, or from creating any type of nuisance or health hazard. Sewage facilities shall be of such capacity to adequately serve all users of the park at peak periods. Running water from a tested and approved supply designed for a minimum flow of 200 gallons per day per manufactured home site shall be piped to each manufactured home. All sanitary sewer and water facilities shall conform to minimum State and County Health regulations and other applicable sections of this Code of Ordinances. Storm drainage facilities shall be so constructed as to protect those who reside in the manufactured home park as well as the property owners adjacent to the park. Such park facilities shall be of such capacity to insure rapid drainage and prevent the accumulation of stagnant pools of water in or adjacent to the park;

   N.   All electric, telephone, and other lines from supply poles outside the park or other sources to each manufactured home shall be placed underground.

   O.   Any fuel storage shall be in accordance with applicable federal, State, and local regulations.

   P.   All roads, driveways, and motor vehicle parking spaces shall be paved and constructed so as to handle anticipated peak loads and be adequately drained and lighted for safety and ease of movement of pedestrians and vehicles.

   Q.   All manufactured home parks shall be provided with safe and convenient vehicular access from abutting public and private streets or roads to each manufactured home site. Alignment and gradient shall be properly adopted to topography. Access to manufactured home parks shall be designed to minimize congestion and hazards at the entrance or exit and allow free movement of traffic on adjacent streets. The entrance road connecting the park streets with a public street or road shall have minimum road pavement width of 41 feet where parking is permitted on both sides, or a minimum road pavement width of 31 feet where parking is limited to one side. When primary entrance road is more than 100 feet long and does not provide access to abutting manufactured home lots within such distance, the minimum road pavement width may be 24 feet; with parking limited to one side, 31 feet; and with parking permitted on both sides, 41 feet.

   R.   Required standards for roadways, parking, and traffic shall be as follows:

 

 

   S.   If any dead-end place or court is more than 250 feet in length, it shall terminate in an open space, preferably circular, and have a minimum dimension of 100 feet. Except in unusual instances, no dead-end street or place shall exceed 600 feet in length.

   T.   All streets of a manufactured home park providing ingress and egress from an abutting public street or road shall have the location and design of intersection with said public street or road approved by the City and by any other governmental agency exercising control over such streets or roads.

   U.   All parks shall be furnished with lighting units spaced and equipped with approved fixtures, placed at mounting heights that will provide the following average maintained levels of illumination for safe movement of pedestrians and vehicles at night:

      (1)   All parts of the park street system 0.6 foot-candle, with a minimum of 2.5 foot-candle.

      (2)   Potentially hazardous locations, such as major street intersections and steps or stepped ramps, individually illuminated with a minimum of 0.4 foot-candle.

   V.   All streets intended for general public use shall be dedicated as a public right-of-way and subject to such improvements as may be required by the City.

   W.   All streets intended primarily for use of park occupants, guests, and services shall be owned and maintained by the manufactured home park owner. Private streets shall be constructed with either hot mix asphaltic concrete or Portland cement concrete to provide for drainage, and shall be constructed to specifications approved by the City. Street surfaces shall be maintained free of cracks, holes, and other hazards.

   X.   Grades of all streets shall be sufficient to insure adequate surface drainage, and shall have prior approval of the City before commencing of construction.

   Y.   Streets shall be at approximately right angles within 50 feet of an intersection. A distance of at least 100 feet shall be maintained between center line of off-set intersecting streets unless specifically approved by the City. Intersections of more than two streets at one point shall be avoided.

   Z.   The limits of each manufactured home site shall be clearly marked on the ground by permanent steel or iron rods driven into the ground with the top of said rods flush with the finished lot grade. Location of lot limits on the ground shall be approximately the same as shown on the approved plans. The degree of accuracy obtainable by working with a scale on the plan and then a tape on the ground is acceptable. Precise engineering of lot limits is not required either on the plans or on the ground. This is not to be construed as permitting lots of a lesser size than the required minimum or permitting lesser yard or setback dimensions than set forth elsewhere in this chapter.

   AA.   No manufactured home shall be connected to water, sewer, or electrical service unless the manufactured home complies with the standards and requirements prescribed by “Standards for Mobile Homes, USAS A119.1, 1963” and amendments thereto, published by the United States of America Standards Institute as applicable, which said publication is hereby adopted and by reference made a part of this chapter, a copy of which is and shall remain on file in the office of the Zoning Officer. Compliance with these standards shall be determined by the Zoning Officer. A certificate, if issued by the manufacturer of the manufactured home, shall be permanently affixed on a readily visible location on the exterior of the manufactured home as prima facia evidence of such compliance.

   BB.   The maximum ground coverage of the manufactured home park shall be 70 percent with the remaining 30 percent reserved for landscaping.
