<br />10th Street to Southwest Corne~ Town Park - (Stations 53~?5 <br /> <br />to 66+00) <br /> <br />This portion consists of two s~ctions. Both involve <br />the construction of new levee. The first subsection would <br />include removal of the existing inadequate levee, while the <br />second subsection would require much less site preparation <br />since there is no existing levee~ <br /> <br />(Stations 52+85 to 61+00) - 815 feet of old levee <br />removal, followed by construction of new levee at an <br />average height of 4 feet (See cross-section B-3). <br /> <br />(Stations 61+00 to 66+00) - 500 feet of new levee at an <br />average height of 5 feet (See cross-section A-A). <br /> <br />'rown Park to Upstream Limits cf Study Reach - Stations 66~OO <br />to 82+40) <br /> <br />Beginning at Station 66+00, two alternative levee <br />alignments exist. Alternative A would turn north to Highway <br />145 immeCliately, while Alternative B would continu'O for an <br />additional 1/4 mile along the riverbank before turning <br />:1orth. Each would involve cons~ruction of new levee. An <br />important difference to note at ~he beginning is that <br />;~lternative A would not protect the Dolo~es Watey Treatment <br />::-acility, while J-,~ternative B vlOi.1~.C. <br /> <br />Alternative A <br /> <br />This alternative cons~sts of ~wo sec~ions.
