§ 1021. General standards.

In all areas of special flood hazard the following provisions are required:

(a)

Anchoring. New construction and substantial improvements of existing structures shall be anchored to prevent flotation, collapse or lateral movement of the structure.

(b)

Flood-resistant materials. New construction and substantial improvements of existing structures shall be constructed with materials and utility equipment resistant to flood damage.

(c)

Construction methods and practices. New construction or substantial improvements of existing structures shall be constructed by methods and practices that minimize flood damage.

(d)

Heating and air conditioning. All heating and air conditioning equipment and components (including ductwork), all electrical, ventilation, plumbing, and other service facilities shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

(e)

Manufactured homes. Manufactured homes shall be anchored to prevent flotation, collapse, or lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This standard shall be in addition to and consistent with applicable state requirements for resisting wind forces.

(f)

Water supply. New and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.

(g)

Sewage systems. New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters.

(h)

On-site sewage disposal systems. On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding.

(i)

Nonconformities. Any alteration, repair, reconstruction or improvement to a structure, which is not compliant with the provisions of this UDC, shall be undertaken only if the non-conformity is not furthered, extended or replaced.
