Also, the <br />Main Street bridge would be overtopped by the 500 year event. <br /> <br />No mill structures are within the 500 year floodway. The cross <br />sections in the Appendix show the relationship of the offices, ware- <br />house and "A" Plant to the flood crest elevation. <br /> <br />4.0 CONCLUSIONS <br /> <br />A routing of the 500 year frequency flood through the San Miguel <br />river channel has indicated that no mill structures in t:',e "P," <br />Plant are directly affected by the flood waters.
