Current through Register Vol. 43, No. 39, September 26, 2024
(a)
(1) A geometric analysis shall not be used if
any existing or proposed levees or floodplain fills are located, or proposed to
be located, within the lesser of the following distances measured from the
boundaries of the proposed levee or floodplain fill:
(A) Five times the width of the water surface
during a base flood, as measured both upstream and downstream; and
(B) 1,320 feet, as measured both upstream and
downstream.
(2) The
prohibition specified in paragraph (a)(1) shall not apply if the applicant
demonstrates that the effects of the existing or proposed levee or floodplain
fill projects are included in the analysis in a technically valid manner.
(b) If the geometric analysis shows that the increase in the base flood elevation that will be caused by the proposed project will cause an unreasonable effect, the applicant shall meet one of the following requirements:
(1) Submit a hydrologic analysis meeting the
requirements of K.A.R. 5-45-14 and demonstrating that the proposed project will
not cause an unreasonable effect, as determined by the geometric analysis; or
(2) modify the design of the
proposed floodplain fill or levee so that the proposed project will not cause
an unreasonable effect, as determined by the applicant's geometric or
hydrologic analysis. If the project cannot be modified so that it will not
cause an unreasonable effect, the application for the approval shall be denied.
