Title 13 BUILDINGS AND CONSTRUCTION
Chapter 13.12 FLOOD DAMAGE PREVENTION
13.12-3.020 Development permit and certification requirements.
Application for a development permit shall be made to the
local administrator on forms furnished by him or her prior to any development
activities. The development permit 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; and the
location of fill materials, storage areas, and drainage facilities.
Specifically, the following information is required:
A. A plot plan that shows the one-hundred-year floodplain
contour or a statement that the entire lot is within the floodplain must be
provided by the development permit applicant when the lot is within or appears
to be within the floodplain as mapped by the Federal Emergency Management Agency
or the floodplain identified pursuant to either subsection 13.12-3.030(J) or
Sections 13.12-4.030 and 13.12-4.040. The plot plan must be prepared by or under
the direct supervision of a registered land surveyor or professional engineer
and certified by same.
B. The plot plan required by subsection 13.12-3.020(A) must
show the floodway, if any, as identified by the Federal Emergency Management
Agency or the floodway identified pursuant to either subsection 13.12-3.030(J)
or Sections 13.12-4.030 and 13.12-4.040.
C. Where base food elevation data is provided as set forth in
Section 13.12-1.040 or subsection 13.12-3.030(J), the application for a
development permit within the flood hazard area shall slow:
1. The elevation (in relation to mean sea level) of the
lowest floor of all new and substantially improved structures; and
2. If the structure will be floodproofed in accordance with
subsection 13.12-4.020(B), the elevation (in relation to mean sea level) to
which the structure will be floodproofed.
D. If no base flood elevation data is provided as set forth
in Section 13.12-1.040 or subsection 13.12-3.030(J), the application for a
development permit must show construction of the lowest floor at least three
feet above the highest adjacent grade.
E. Where any watercourse will be altered or relocated as a
result of proposed development, the application for a development permit shall
include: a description of the extent of watercourse alteration or relocation; an
engineering report on the effects of the proposed project on the flood-carrying
capacity of the watercourse and the effects to properties located both upstream
and downstream; and, a map showing the location of the proposed watercourse
alteration or relocation.
F. When a structure is floodproofed, the applicant shall
provide certification from a registered, professional engineer or architect that
the non-residential, floodproofed structure meets the floodproofing criteria in
subsection 13.12-4.020(B)
G. A floor elevation or floodproofing certification is
required after the lowest floor is completed. As soon as possible after
completion of the lowest floor and before any further vertical construction
commences, or floodproofing by whatever construction means, whichever is
applicable, it shall be the duty of the permit holder to submit to the local
administrator a certification of the elevation of the lowest floor, or
floodproofed elevation, whichever is applicable, as built, in relation to mean
sea level. Said certification shall be prepared by or under the direct
supervision of a registered land surveyor or professional engineer and certified
by same. Any work done prior to submission of the certification shall be at the
permit holder’s risk. The local administrator shall review the floor
elevation survey data submitted. Deficiencies detected by such review shall be
corrected by the permit holder immediately and prior to further progressive work
being permitted to proceed. Failure to submit the survey or failure to make said
corrections required hereby shall be cause to issue a stop-work order for the
project.
H. When a structure is located in Zones V, VE, or V1-30,
certification shall be provided from a registered professional engineer or
architect, separate from submitted plans, that new construction or substantial
improvement meets the criteria in subsection 13.12-4.070(E).
I. Upon completion of the development a registered
professional engineer, land surveyor or architect, whichever professional is
appropriate, shall certify that subsections 13.12-3.020(F), (G) and (H) are
built in accordance with the submitted plans and previous pre-development
certifications.
J. If the proposed project will impact the configuration of
the watercourse, floodway, or base flood elevation for which a detailed flood
insurance study has been developed, the applicant shall apply for and must
receive approval for a conditional letter of map revision with the Federal
Emergency Management Agency prior to actual construction.
K. Within sixty (60) days of completion of an alteration of a
watercourse, referenced in subsection 13.12-3.020(J), the applicant shall submit
as-built certification, by a registered professional engineer, to the Federal
Emergency Management Agency. (Ord. 01-O-06 § 1(part), 2001)
