Evaluate Existing Levee (levee integrity and reliability based on Corps criteria) <br />. Identify Level of Protection (assuming the levee meets Corps criteria) <br />. Effects of the levees on existing conditions' flood boundaries <br />. Most practical type of closure structure and preliminary cost estimate <br /> <br />Bac~round information <br /> <br />Area Description <br />. Area to South of new levee is residential <br />. Area to North is open fannland <br />. Variety of trees in vicinity oflevee <br />. Levee ties into Park levee to East <br />. Levee ties into abandoned rail road to west <br />. Boone street cuts through the levee near the West end <br /> <br />Flooding] 993 <br />. Sandbags were placed approximately two feet above levee <br />. Boone Street was closed with sandbags <br /> <br />Levee Construction <br />. Levee was constructed after 1993 flooding <br />. Levee was constructed approximately to the height of the sandbags (approximately <br />two feet) <br />. DGR has plans of the levee while it was sandbagged <br />. New levee has 12' top width and approximately 2.5:1 side slopes (verbal <br />confirmation from DGR). Slopes were steepened from original 3: I due to property <br />and R.O.W. constraints <br />. Sloped are vegetated <br />. 95% compaction was speced, used medium size sheepsfoot roller for compaction <br />. Levee material came from South Tama Street construction (clayey material) <br />. Height of new levee is approximately 1344.5 feet according to DGR plans <br />. Levees range from 6' -9' in height according to DGR plans <br />. Slopes are vegetated <br /> <br />Ilydraulics <br /> <br />. Cross section ends at tie in point between new levee and PlIIk levee <br />. Area determined to be ineffective flow and therefore no impact to water surface elevation <br /> <br />SITE B - page I <br />
