§ 30.56.060. General Grounds for Application Approval/Denial.
The application for a Floodplain Development Permit shall be approved if the Issuing Authority makes a finding that the proposal meets and is consistent with each of the applicable findings shown below. The failure of the proposal to meet and be consistent with each of the applicable findings shown below shall be grounds for denial of the application. Such denial shall be supported by written findings of fact by the Issuing Authority as to how the application fails to meet one or more of the following findings:
The proposed new construction or substantial improvement:
A.
Will not violate the building or zoning regulations of the City.
B.
Will be anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.
C.
Will be constructed with materials and utility equipment resistant to flood damage.
D.
Will use methods and practices that minimize flood damage.
E.
Will involve a residential structure in an A, AE or AH Zone, and will have the lowest floor (including basement) of such structure elevated at or above the base flood elevation.
F.
Will involve a manufactured home that will be elevated on a permanent foundation such that the lowest floor is at or above the base flood elevation and is securely anchored to an adequately anchored foundation system.
G.
Will involve a nonresidential structure and will have the lowest floor (including basement) elevated to or above the base flood level or, together with attendant utility and sanitary facilities will be floodproofed below the base flood level to the extent that the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy, as certified by a registered professional engineer or architect.
H.
Will be in an area of shallow flooding (Zone AO on the community's FIRM) and will have the lowest floor (including basement) elevated at or above the depth number indicated on the most current FIRM; or if there is no depth number on the most current FIRM, the structure will be elevated at least three feet above the highest adjacent grade. As an alternative, nonresidential structures, together with attendant utility and sanitary facilities, may be floodproofed to that level as specified in this Chapter.
I.
Will be in Zones AO and AH on the FIRM and will have adequate drainage paths around structures situated on sloping ground, to guide floodwaters around and away from said structures.
J.
Will involve the floodproofing of a nonresidential structure using a design and/or methods of construction that are in accordance with accepted standards of practice for floodproofing or which will extend the floodproofing to an elevation which is required pursuant to the provisions of this Chapter.
K.
Will have all new and replacement water supply and sanitary sewage systems designed to minimize or eliminate infiltration of flood waters into the system and discharges from the system into flood waters.
L.
Will have on-site waste disposal systems located to avoid impairment to them, or contamination from them, during flooding.
M.
Will have all electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
N.
Will have all fully enclosed areas below the lowest floor that are subject to flooding designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters with designs certified by a registered professional engineer or architect; or will have at least two openings no more than one foot above grade with a total net area of at least one square inch per square foot of flooded area.
O.
Will be located in an area that is reasonably safe from flooding.
P.
Will not adversely affect the carrying capacity of areas where base flood elevations have been determined but a floodway has not been established. For purposes of this Section, "adversely affects" shall mean that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will increase the water surface elevation of the base flood elevation more than one foot at any point.
Q.
Will not be sited and designed so as to require the construction or installation of flood protective works.
