A development permit shall be obtained before construction or development begins within any area of special flood hazard established in §
74-8. Application for a development permit shall be made on forms furnished by the Floodplain Official and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevations of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities, and the location of the foregoing. Specifically, the following information is required:
A. Elevation in relation to mean sea level of the lowest
floor (including basement) of all structures;
B. Elevation in relation to mean sea level to which any
structure has been floodproofed;
C. Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in §
74-21B; and
D. Description of the extent to which any watercourse
will be altered or relocated as a result of proposed development.
The Floodplain Official is responsible for administering
and implementing this chapter by granting or denying development permit
applications in accordance with its provisions. The Floodplain Official
will normally be the City Engineer.
Duties of the Floodplain Official shall include,
but not be limited to:
A. Permit review. The Floodplain Official shall:
(1) Review all development permits to determine that the
permit requirements of this chapter have been satisfied.
(2) Review all development permits to determine that all
necessary permits have been obtained from those federal, state or
local governmental agencies from which prior approval is required,
including Section 404 of the Federal Water Pollution Control Act Amendments
of 1972, 33 U.S.C. § 1334.
(3) Review all development permits to determine if the
proposed development adversely affects the flood-carrying capacity
of the area of special flood hazard. For purposes of this chapter,
"adversely affects" means the cumulative effects of proposed development
when combined with all other existing and anticipated developments
increases the water surface elevation of the base flood more than
one foot at any point.
B. Use of other base flood data. When base flood elevation data has not been provided in accordance with §
74-8, Basis for establishing the areas of special flood hazard, the Floodplain Official shall obtain, review and reasonably utilize any base flood elevation data and floodway data available from a federal, state or other source, in order to administer §
74-21, Specific Standards, Subsection
A, Residential construction, and Subsection
B, Nonresidential construction.
C. In special flood hazard areas, the Floodplain Official
shall determine the one-hundred-year-flood elevation in the following
order of precedence according to the data available:
(1) In Zones AE, refer to the elevation data provided
in the community's Flood Insurance Study and accompanying FIRM.
D. Information to be obtained and maintained. The Floodplain
Official shall:
(1) Obtain and record the actual elevation (in relation
to mean sea level) of the lowest floor (including basement) of all
new or substantially improved structures located in Zones A or AE.
The applicant shall furnish the following information to the Building
Inspector.
(2) For all new or substantially improved floodproofed
structures:
(a)
Verify and record the actual elevation (in relation
to mean sea level); and
(b)
Maintain the floodproofing certifications required in §
74-14C.
(3) Maintain for public inspection all records pertaining
to the provisions of this chapter.
