Conclusion <br /> <br />The downstream water surface elevation ties to 0.08 feet of the existing condition analysis, <br />which is within the tolerance specified by FEMA. The proposed channel reduces the peak <br />velocity from the 198 I study and the existing conditions analysis. This will help to prevent <br />erosion in the channel. <br /> <br />David Evans and Associates, lnc. <br /> <br />3 <br />
