Floodway widths were computed at <br />cross sections. Between cross sections, the floodway boundaries <br />were interpolated. The results of the floodway computations are <br />tabulated at selected cross sections (Table 2). In cases where <br />the floodway and 100-year flood plain boundaries are either close <br />together or collinear, only the floodway boundary has been shown. <br /> <br />The area between the floodway and 100-year flood plain boundaries <br />is termed the floodway fringe. The floodway fringe encompasses <br />the portion of the flood plain that could be completely obstructed <br />without increasing the water-surface elevation of the 100-year <br />flood by more than 1.0 foot at any point. Typical relationships <br />between the floodway and the floodway fringe and their <br />significance to flood plain development are shown in Figure 2. <br /> <br />12 <br />
