15.32.150: SPECIFIC PROVISIONS FOR FLOOD HAZARD REDUCTION FOR MANUFACTURED HOMES:
In all areas of special flood hazard where the base flood elevation is established, these standards for manufactured homes apply:
   A.   All manufactured homes placed or substantially improved in the following areas must have the lowest floor, including basement, elevated to the flood protection elevation:
      1.   On individual lots or parcels;
      2.   In new or substantially improved manufactured home parks or subdivisions; and
      3.   In expansions to existing manufactured home parks or subdivisions, or on a site in an existing manufactured home park or subdivision where a manufactured home has incurred "substantial damage" as the result of a flood.
   B.   Manufactured homes placed or substantially improved in an existing manufactured home park or subdivision must be elevated so that either:
      1.   The lowest floor of the manufactured home is elevated to the flood protection elevation or one foot (1') above the level of the base flood elevation, whichever is higher; or
      2.   The manufactured home chassis is elevated and supported by reinforced piers (or other foundation elements of at least an equivalent strength) of no less than thirty six inches (36") above the highest adjacent grade.
   C.   Manufactured homes must be anchored to prevent flotation, collapse, or lateral movement. Methods of anchoring include, but are not limited to, use of over the top or frame ties to ground anchors. This standard applies in addition to, and consistent with, all applicable state requirements.
   D.   Manufactured homes placed on solid perimeter walls must meet the flood vent requirements in section 15.32.130 of this chapter. (Ord. 3380 §7, 2010)
