Conveyance zone definition
Conveyance zone means those portions of the floodplain required for the passage or conveyance of the one hundred-year flood. The conveyance zone is delineated based on an equal encroachment methodology (measured in volume of water), which is applied to the floodplain from the edges of the flood channel to a point where the one hundred-year flood profile will be raised no more than six inches, after considering a reasonable expectation of blockage at bridges and other obstructions by flood borne debris. The city may, in its discretion, delineate the conveyance zone on city owned land or right of way based on unequal encroachment to minimize delineation on other properties. The conveyance zone is equivalent to a floodway delineation based on a six inch rise. (Floodplain and Critical Facilities)
