APPENDIX B <br /> 100-YEAR STORM CALCULATIONS <br /> This proposed bridge design is more than adequate to safely pass the flow <br /> generated by a 100-year storm event. A conservative method of flow estimate <br /> shows a 100-year storm event to yield 15,700 cfs at the bridge site. This <br /> bridge design can pass this 100-year storm flow with 2.5 feet of freeboard <br /> remaining. With 0.5 feet of freeboard remaining the bridge would allow a flow <br /> of 19,900 cfs. The methodology used and calculations follow this page. <br />
