All manufactured homes installed in flood hazard areas shall be installed by an installer that is licensed pursuant to the Business and Professions Code and shall comply with the requirements of the Department of Housing and Community Development (HCD) and the requirements of these regulations. In addition to permits pursuant to these regulations, permits from the HCD are required where the HCD is the enforcement agency for installation of manufactured homes. Upon completion of installation and prior to the final inspection by the Floodplain Administrator, the installer shall submit certification of the elevation of the manufactured home, prepared by a licensed land surveyor or registered civil engineer, to the Floodplain Administrator.
(Ord. CS 1301 §2, 2021)
All new and replacement manufactured homes, including substantial improvement of manufactured homes installed in flood hazard areas shall be installed on permanent, reinforced foundations that are designed in accordance with the foundation requirements of Section R322.2 of the residential code (CCR Title 24 Part 2.5) and these regulations. Foundations for manufactured homes subject to Section 16.50.935 of these regulations are permitted to be reinforced piers or other foundation elements of at least equivalent strength.
(Ord. CS 1301 §2, 2021)
All new and replacement manufactured homes to be placed or substantially improved in a flood hazard area shall be installed using methods and practices which minimize flood damage and shall be securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement. Methods of anchoring are authorized to 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 and local anchoring requirements for resisting wind loads and seismic loads.
(Ord. CS 1301 §2, 2021)
Unless subject to the requirements of Section 16.50.935 of these regulations, all manufactured homes that are placed, replaced, or substantially improved on sites located: (a) outside of a manufactured home park or subdivision; (b) in a new manufactured home park or subdivision; (c) in an expansion to an existing manufactured home park or subdivision; or (d) in an existing manufactured home park or subdivision upon which a manufactured home has incurred "substantial damage" as the result of a flood, shall be elevated such that the lowest floor, or bottom of the lowest horizontal member of the lowest floor, as applicable to the flood hazard area, is at or above the base flood elevation.
(Ord. CS 1301 §2, 2021)
Manufactured homes that are not subject to Section 16.50.934 of these regulations, including manufactured homes that are placed, replaced, or substantially improved on sites located in an existing manufactured home park or subdivision, unless on a site where substantial damage as a result of flooding has occurred, shall be elevated such that either the:
A. 
Lowest floor, or bottom of the lowest horizontal structural member, as applicable to the flood hazard area, is at or above the base flood elevation.
B. 
Bottom of the frame is supported by reinforced piers or other foundation elements of at least equivalent strength that are not less than thirty-six inches in height above grade.
(Ord. CS 1301 §2, 2021)
Materials below elevated manufactured homes shall comply with the flood-damage resistant materials requirements of Section R322 of the residential code (CCR Title 24 Part 2.5).
(Ord. CS 1301 §2, 2021)
Fully enclosed areas below elevated manufactured homes shall comply with the enclosed area requirements of Section R322 of the residential code (CCR Title 24 Part 2.5).
(Ord. CS 1301 §2, 2021)
Mechanical equipment and outside appliances shall be elevated to or above the lowest floor or bottom of the lowest horizontal structural member of the manufactured home, as applicable to the flood hazard area.
Exception. Where such equipment and appliances are designed and installed to prevent water from entering or accumulating within their components and the systems are constructed to resist hydrostatic and hydrodynamic loads and stresses, including the effects of buoyancy, during the occurrence of flooding up to the elevation required by Section 16.50.934 or 16.50.935, as applicable, the systems and equipment shall be permitted to be located below that elevation. Electrical wiring systems shall be permitted below the design flood elevation provided they conform to the provisions of NFPA 70 (National Electric Code).
