(A) Manufactured homes. New manufactured home parks, expansions to existing manufactured home parks, and new or replacement manufactured home units on lots of record are prohibited in the Floodway District. If allowed in the Flood Fringe District, these uses are subject to the requirements of § 154.090 and the following standards.
(B) Placement of manufactured homes. New and replacement manufactured homes in the Flood Fringe District must comply with the following standards:
(1) New and replacement manufactured homes must be elevated in compliance with § 154.090 and must be securely anchored to an adequately anchored foundation system that resists flotation, collapse and lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state or local anchoring requirements for resisting wind forces.
(2) New or replacement manufactured homes in existing manufactured home parks must meet the vehicular access requirements for subdivisions in § 154.092(B)(2).
(C) Recreational vehicles. Placement of recreational vehicles in the floodplain must meet the exemption criteria below or be treated as new structures meeting the requirements of this subchapter.
(1) Recreational vehicles are exempt from the provisions of this subchapter if they are placed in any of the following areas and meet the criteria listed in division (C)(2) below:
(a) Individual lots or parcels of record.
(b) Existing commercial recreational vehicle parks or campgrounds.
(c) Existing condominium-type associations.
(2) Criteria for exempt recreational vehicles:
(a) The vehicle must have a current license required for highway use.
(b) The vehicle must be highway ready, meaning on wheels or the internal jacking system, attached to the site only by quick disconnect type utilities commonly used in campgrounds and recreational vehicle parks.
(c) No permanent structural type additions may be attached to the vehicle.
(d) The vehicle and associated use must be permissible in any pre-existing, underlying zoning district.
(e) Accessory structures are not permitted within the Floodway District. Any accessory structure in the Flood Fringe District must be constructed of flood-resistant materials and be securely anchored, meeting the requirements applicable to manufactured homes in division (B)(2) above.
(f) An accessory structure must constitute a minimal investment.
(3) Recreational vehicles that are exempt in division (C)(2) above lose this exemption when development occurs on the site that exceeds a minimal investment for an accessory structure such as a garage or storage building. The recreational vehicle and all accessory structures will then be treated as new structures subject to the elevation and floodproofing requirements of § 154.090 above. No development or improvement on the parcel or attachment to the recreational vehicle is allowed that would hinder the removal of the vehicle should flooding occur.
(4) New commercial recreational vehicle parks or campgrounds, subdivisions or condominium associations, and the expansion of any similar existing use exceeding five units or dwelling sites may be allowed subject to the following:
(a) On any new or replacement recreational vehicle site in the Flood Fringe District, the recreational vehicle and its contents must be placed on fill at or above the regulatory flood protection elevation and adequate road access to the site must be provided in accordance with § 154.092(B)(2).
(b) Any new or replacement recreational vehicle site located in the Floodway District or as an alternative to division (C)(4)(a) above in the Flood Fringe District, may be allowed as a conditional use in accordance with the following provisions and the provisions of § 154.095(D).
1. The applicant must submit an emergency plan for the safe evacuation of all vehicles and people acceptable to the City Council as specified in § 154.092(B)(2). The plan must demonstrate that adequate time and personnel exist to carry out an evacuation, and that the exemption provisions of division (C)(1) above will be met; and
2. All attendant sewage and water facilities for new or replacement recreational vehicles must be protected or constructed so as to not be impaired or contaminated during times of flooding in accordance with § 154.093(C).
3. Any fill placed in the floodway to meet the requirements of this section must not increase the flood stage of the regional (1% chance) flood.
