<br />Available depth versus damage tables reflect flood damage due to <br /> <br />standing water. In addition, there is a potential for damage due to <br /> <br />the velocity of the flood water, Erosion and structural damage due to <br /> <br />undermining are possible if the velocities are significant. Data for <br /> <br />estimating this type of damage are not readily available, and it is <br /> <br />recommended the velocity head be added to the flood depth when velocities <br /> <br />exceed 8 fps, to account for some of the damage that might occur. <br /> <br />If a comparison of the existing and future flood damages is desired, <br /> <br />then flood damages must be computed for the existing situation using the <br /> <br />ex.U.Ung 6.toodpWno defined in the hydraulic analysis, which are based <br /> <br />on the existing flood hydrology. <br /> <br />Step 9 - Compute the Average Annual Flood Damage Potential <br /> <br />Total the flood damages for each reach and recurrence interval. <br /> <br />Tables such as the one below should be constructed: <br /> <br />Table III-6 <br /> <br />SUMMARY OF FLOOD DAMAGES FOR REACH <br /> <br />Area: Little Dry Creek above Cinderella City <br />Reach: Station 113+21 through 129+00 <br />Frequency: 100 years <br />Conditions: Developed <br />Structure & Content Value Damage <br /> <br />Residential <br /> <br />Commercial <br /> <br />Amount <br /> <br />$420,000 <br />623,000 <br /> <br />Other Damages <br />Loss of Sales <br />Removal of Debris - public <br />Removal of Debris - Residential <br />Removal of Debris - Commercial <br /> <br />Damage to Public Utilities <br />Loss of Rents <br />Loss of Life <br />Total Damage <br /> <br />210,000 <br />12,000 <br />2,000 <br />6,000 <br />3,000 <br />4,000 <br />500 <br />$1,280,500 <br /> <br />, <br /> <br />74 <br />
