The mayor of Alamosa declared an <br />emergency and mobilized private contractors to construct a <br />secondary levee in order to control the seepage problem. The <br />levee consisted of a row of loose dirt and sand bags, placed <br />west and parallel to the levee, along an existing bike path. <br />The secondary levee was about 3 feet high. Following the <br />recession of the peak of the flood, the secondary levee was <br />removed but levee seepage remains a concern. <br /> <br />Findings: <br /> <br />~ <br />~ <br />--i1 <br /> <br />The levee opposite Cole Park, for a d~icstance of about <br />2,000 feet upstream of the highway bridge, has numerous trees <br />growing on the river side and a row of well established <br />cottonwood trees along the toe of the park side. During the <br />flood, : sand boils were reported near the base of the some of <br />the' trees. It is suspected that water may be piping along the <br />tree roots that may extend into the embankment, <br /> <br />,I <br /> <br />L <br />. <br /> <br />I <br /> <br />, <br />~ <br /> <br />... <br /> <br />71 <br />
