<br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />Small low level crossing structures such as foot bridges were not included <br /> <br />in the detailed analysis. It is assumed that these structures w,iJl be washed <br /> <br /> <br />out during a major flood and will not cause significant backwater. <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />It is recommended that the hydraulic capacities of both the stream <br /> <br /> <br />channel and the hydraulic structures (particularly bridges) be maintained <br /> <br /> <br />by keeping them clear of debris. This can be accomplished through a regular <br /> <br /> <br />maintenance program and onsite cleaning operations during flood periods, <br /> <br />Trees have fallen across the river in a number of areas and may restrict <br /> <br />flood waters (Stations 75+00, 84+00, 92+00, 138+00, 153+00, 185+00). For <br /> <br /> <br />example, the fallen tree near Station 153+00 has a 6 foot diameter trunk. <br /> <br /> <br />Continued debris accumulation against this tree may potentially force a channel <br /> <br />shift to the south. <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />{ <br /> <br />I <br /> <br />I <br /> <br /> <br />I <br /> <br />-28- <br /> <br />I <br /> <br />M <br /> <br />el <br />~ <br /> <br />'" <br />~ <br />.... <br />!;: ~ <br />:> <br />'" <br />0-1 <br />'" <br />'" <br />o <br />o <br />0-1 <br />r.. <br />'" <br />'" <br />:> <br />.... <br />'" <br /> <br />'" <br />< <br />~ <br />~ <br /> <br />:Il <br />E-< <br />=- <br />o <br />'" <br /> <br />.... <br />Q) <br />> <br />Q) <br />0-1 <br /> <br />.. <br />Q) <br />'" <br /> <br />" <br />.. <br />~ <br /> <br />Q) <br />> <br />o <br />~ <br /> <br />" <br />Q) <br />Q) <br />r.. <br />~ <br /> <br />>. <br />u <br />" <br />Q) <br />" <br />C' <br />Q) <br />... <br />r.. <br />... <br />.. <br />Q) <br />>< <br />I <br />o <br />o <br />'" <br /> <br />Q) <br />eo <br />... <br />..
