"Pr fl likely to occur from a
combination of the most critical meteorological and hydrological conditions that are
reasonably possible in the drainage basin according to publications of the National
Oceanic and Atmospheric Administration. Usually much greater than the 100-year
flood.
"Regu/atory floodway" The channel of a river or other watercourse and the adjacent
land areas that must be reserved in order to discharge the base flood without
cumulatively increasing the water surface elevation more than a designated height.
"Renm~ a v/o/at/on" To bring the structure or other development into compliance
with these, State, or FEMA floodplain management regulations or ff this is not
possible, to reduce the impacts of its noncompliance. Ways that impacts may be
reduced include protecting the structure or other affected areas from flood-related
erosion or damages, implementing the enforcement provisions of the ordinance or
otherwise deterring future similar violations.
"R/vet/ne" Relating to, formed by, or resembling a river, stream, creek, brook, etc.
(including tributaries).
"Sheet flow area" Overland flow of surface water runoff of shallow depth and evident
velocity. See "Area of shallow flooding."
"S/n~M F/ood Hazard Areff' (SFHA) The land in the floodplain area within the City
subject to flooding and shown on a FHBM or FIRM as Zone A, AE, AH, AO, or A1-
99.
"Standard Project F/ood" The flood established for the design of levees, dams, or
similar flood protection structures subject to sudden failure by flood-related erosion.
A term used by the U.S. Army Corps of Engineers to designate' the most severe flood
considered reasonably characteristic of the location being evaluated, excluding
extremely rare combinations. Generally 40 to 60 percent of the PMF for the same
location.
"Start of co~n" Either the first placement of permanent construction of a
structure on a site, such as the pouring of slab or footings, the installation of piles,
the construction of columns, or any work beyond the stage of eXcavation; or the
placement of a manufactured home on a foundation, provided the actual start of
construction, repair, reconstruction, placement, or other substantial improvement was
within 180 days of the permit issue date. Permanent construction does not include
