TheSe may include river control, water <br />conservation and diversion, power, and water <br />quality structures and related works; remedial or <br />corrective actions including, but not limited to, <br />drainage facilities to assist in controlling <br />adjacent high ground water conditions caused by <br />flood flows; public and tribal roads; military <br />activities; fish and wildlife enhancement projects; <br />navigational aids; emergency action assistance; <br />public health assistance; compatible public, <br />private, and tribal recreational developments such <br />as parks, golf courses, docks, and boat launching <br />ramps; and compatible agricultural uses that do not <br />include permanent crops which would constitute an <br />obstruction to river flood flows; <br /> <br />. Colorado River Floodway Fringe <br /> <br />(B) <br /> <br />Identification of the Colorado River Floodway Fringe <br />establishes the area outside the Floodway subject to <br />inundation when the river's water surface in the Floodway is <br />at its design elevation, a Floodway flow of either a one-in- <br />one hundred year river flow or a flow of forty thousand cubic <br />feet per second, whichever is greater. The Floodway <br />elevation assumes full encroachment of the Floodway Fringe. <br />The following provisions apply: <br /> <br />. <br /> <br />(A) Fill, permanent structures or buildings, including <br />residential structures, may be placed or erected in <br />the Floodway Fringe, provided, in the case of <br />buildings, that the elevation of the lowest <br />floor (including basements) is at least one foot <br />above the Floodway elevation. <br /> <br />(B) Land may be filled, provided the top of the fill <br />shall at no point be below the Floodway elevation <br />for at least twenty-five feet beyond the limits of <br />any structure erected or placed thereon and that <br />the placement of the fill meets the fill compaction <br />criteria of Part 65.5 of the National Flood <br />Insurance Program Regulations. <br /> <br />1II-6 <br />
