Section 4. Delete Section 15.32.270 and replace with the following:
Section 15.32.270 Manufactured homes.
1. All manufactured homes to be placed or substantially improved within Zones Al-A30,
AH and AE on the community's FIRM on sites:
1. Outside of a manufactured home park or subdivision,
2. In a new manufactured home community or subdivision
3. In an expansion to an existing manufactured home community or subdivision, or
4. In an existing manufacture home community or subdivision on which a
manufactured home has incurred "substantial damage" as the result of a flood;
shall be elevated on a permanent foundation such that the lowest floor of the
manufactured home is elevated one foot above the base flood elevation and be securely
anchored to an adequately anchored foundation system to resist flotation collapse and
lateral movement.
2. Manufactured homes to be placed or substantially improved on sites in an existing
manufactured home community or subdivision within Zones Al-A30, AH, and AE on the
community's FIRM that are not subject to the above manufactured home provisions be
elevated so that either:
1. The lowest floor of the manufactured home is elevated one foot above the base
flood elevation, or
2. The manufactured home chassis is supported by reinforced piers or other
foundation elements of at least equivalent strength that are no less than 36
inches in height above grade and be securely anchored to an adequately
anchored foundation system to resist flotation, collapse and lateral movement.
At a minimum a "reinforce pier" would have a footing adequate to support the
weight of the manufactured home under saturated soil conditions which may
occur during flood. In addition, if stacked concrete blocks are used, vertical
steel reinforcing rods should be placed in the hollows of the blocks and those
hollows filled with concrete or high strength mortar. In areas subject to high
velocity floodwaters and debris impact, cast-in-place reinforced concrete piers
may be appropriate.
