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 §
