Reed Wash — Summary of HECRas: Bridge Input Data <br />Revised Date: August 8, 2011 <br />Deck / Roadways Top Chord Elevation = 4,466.12 <br />Low Chord Elevation = 4,461.64 <br />Bridge Length: 116.74 — Feet From East Bridge Abutment to West Bridge <br />Abutment <br />Distance: From Upstream side of Bridge Deck to Cross Section Immediately <br />Upstream of Bridge =12.0 Feet <br />V - •M • <br />Upstream Embankment Side Sloes 2 to 1 <br />Downstream Embankment Side Slope: 2 to 1 <br />Maximum Submergence: 0.95 (Default Value) <br />Weir Shape: Broad Crested <br />Pier Data: <br />Type: HP Shape Steel Pile <br />Size: HP14x102, Flange Width Facing Flow =14 % - Inches = 1.23 — <br />Feet <br />Number of Piers: 5 Each @ 13.84', 15.47', 32.26', 18.94', 18.94' and 17.29' center <br />to center as measured from the Face of the East Bridge Abutment <br />westerly to the Face of the West Bridge Abutment. <br />Ineffective Flow Area Applied to Bridge Sections at: <br />Upstream Cross Section Stations: 1 +31.48 2 +71.00 <br />Downstream Cross Section Stations: 1+31.48 2 +71.00 <br />Skew Angle: 110 37'23" <br />Note: The Bridge Skew Angle was input into the HECRAS Computer Model and was <br />found to have no effect on the calculated water surface elevations. Therefore the <br />Developed Condition HECRAS Computer Model as submitted was completed without a <br />Bridge Skew Angle. <br />Appendix RW -E.1 <br />
