The city council hereby resolves to act in the following manner:
(A) Floodplain Control Measures:
(1) To assure the federal insurance administration that it will enact as necessary, and maintain in force for those areas having flood or mudslide hazards, adequate land use and control measures with effective enforcement provisions consistent with the criteria set forth in section 1910 of the national flood insurance program regulations.
(2) To vest the building official with the responsibility, authority and means to:
(a) Delineate or assist the administrator, at his request, in delineating the limits of the areas having special flood (and/or mudslide) hazards on available local maps of sufficient scale to identify the location of building sites.
(b) Provide such information as the administrator may request concerning present uses and occupancy of the floodplain (and/or mudslide area).
(c) Cooperate with federal, state and local agencies and private firms which undertake to study, survey, map and identify floodplain or mudslide areas and cooperate with neighboring communities with respect to management of adjoining floodplain and/or mudslide areas in order to prevent aggravation of existing hazards.
(d) Submit on the anniversary date of the community's initial eligibility an annual report to the administrator on the progress made during the past year within the community in the development and implementation of floodplain (and/or mudslide area) management measures.
(3) To appoint the building official of the city to maintain for public inspection and to furnish upon request a record of elevations (in relation to mean sea level) of the lowest floor (including basement) of all new or substantially improved structures located in the special flood hazard areas. If the lowest floor is below grade on one or more sides, the elevation of the floor immediately above must also be recorded.
(4) Agree to take such other official action as may be reasonably necessary to carry out the objectives of the program.
(B) Building Construction Restrictions:
(1) The building official shall review all building permits 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:
(a) Be designed (or modified) and anchored to prevent flotation, collapse or lateral movement of the structure;
(b) Use construction materials and utility equipment that are resistant to flood damage; and
(c) Use construction methods and practices that will minimize flood damage.
(2) The city planning commission shall review subdivision proposals and other proposed new developments to assure that:
(a) All such proposals are consistent with the need to minimize flood damage;
(b) 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
(c) Adequate drainage is provided so as to reduce exposure to flood hazards.
(3) The city engineer shall require new or replacement water supply systems and/or sanitary 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.
