14.20.010 Development in mudflow-prone areas.

(a)    The building code compliance department shall require the issuance of a permit for any excavation, grading, fill or construction in the mudflow-prone areas of the community.

(b)    The building code compliance department shall require review of each permit application to determine whether the proposed site and improvements will be reasonably safe from mudflows. If a proposed site and improvements are in a location that may have mudflow hazards, a further review must be made by persons qualified in geology and soils engineering; and the proposed new construction, substantial improvement or grading must:

(1)    Be adequately protected against mudflow damage; and

(2)    Not aggravate the existing hazard.

(Res. 11-1975 §§ 1, 2, 1975)

14.20.020 Development in flood-prone areas.

(a)    The building code compliance department shall review all building permit applications for new construction or substantial improvements to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is in a location that has a flood hazard, any proposed new construction or substantial improvement (including prefabricated and mobile homes) must:

(1)    Be designed (or modified) and anchored to prevent flotation, collapse or lateral movement of the structure;

(2)    Use construction materials and utility equipment that are resistant to flood damage; and

(3)    Use construction methods and practices that will minimize flood damage.

(b)    The engineering department and/or public works department shall review subdivision proposals and other proposed new developments to assure that:

(1)    All such proposals are consistent with the need to minimize flood damage;

(2)    All public utilities and facilities, such as sewer, gas, electrical and water systems, are located, elevated and constructed to minimize or eliminate flood damage; and

(3)    Adequate drainage is provided so as to reduce exposure to flood hazards.

(c)    The health department shall require new or replacement water supply systems and/or sanitary sewage systems to be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwaters, and require on-site waste disposal systems to be located so as to avoid impairment of them or contamination from them during flooding.
