After <br /> <br /> <br />reaching the vicinity of 13th Avenue the flow turns east causing <br /> <br /> <br />flooding of properties south of 13th Avenue, between Van Gordon <br /> <br /> <br />Street and Union Street. <br /> <br />Street to a depth of approximately 1.5 feet and causes flooding <br /> <br /> <br />west of Quail Street. NO residential structures are located in <br /> <br /> <br />the tloodplain between Quail Street and Oak Street. The flooding <br /> <br /> <br />between Oak Street and Kipling Street is caused by backwater <br /> <br /> <br />from the culvert under Kipling Street. Two residential structure~ <br /> <br /> <br />immediately west of Kipling Street lie within the illustrated <br /> <br /> <br />floodplain. Three small non-residential structures located <br /> <br /> <br />within the floodplain can be expected to be damaged by flood- <br /> <br /> <br />waters. <br /> <br />At Union Street and Lakewood Gulch another portion of the flow <br /> <br /> <br />carried in the main channel of Lakewood Gulch splits off due to <br /> <br /> <br />a small culvert crossing. The portion flowing north along Union <br /> <br /> <br />Street joins the flow from Van Gordon Street before turning east <br /> <br /> <br />to flow over the Agricultural Ditch. Properties along Pleasant <br /> <br /> <br />Avenue are flooded before the water returns to Lakewood Gulch. <br /> <br /> <br />The Agricultural Ditch, which crosses the Gulch immediately <br /> <br /> <br />east of Union Boulevard, is elevated with respect to the Gulch <br /> <br /> <br />and causes no problem for the main channel. The culvert under <br /> <br /> <br />Si~~s Street is too small to convey the 100-year flood. The <br /> <br /> <br />result is a backup of water inundating several structures west <br /> <br /> <br />of Simms Street. <br /> <br />Simms Street to Kipling Street (Sheets 7, 8, 9) <br /> <br /> <br />All the crossings within this reach are too small to handle the <br /> <br /> <br />projected 100-year flood. The resulting floodplain is up to <br /> <br /> <br />600 feet wide with varying depth. The floodplain between Simms <br /> <br /> <br />and Quail Streets is influenced by the culvert under the Asso- <br /> <br /> <br />ciated Railroad and under Simms Street. The backwater created <br /> <br /> <br />by the culvert under Quail Street causes overtopping of Quail <br /> <br />Kipling Street to Garrison Street (Sheets 9, 10) <br /> <br /> <br />Two small structures located south of W. 10th Avenue are expec- <br /> <br /> <br />ted to be inundated by backwater caused from culvert under Inde- <br /> <br /> <br />pendence Street. The culvert under Independence Street is too <br /> <br /> <br />small to carry the 100-year flood and overtopping can be expec- <br /> <br /> <br />ted at a depth of approximately 2 feet. The crossing at Garrison <br /> <br /> <br />Street has sufficient hydraulic capacity to permit passage of the <br /> <br /> <br />projected 100-year flood. Backwater is generated but no inunda- <br /> <br /> <br />tion of residential structures is anticipated. <br /> <br />Garrison Street to Wadsworth Boulevard (Sheets 10, II, 12, 13) <br /> <br /> <br />Between Garrison Street and Dudley Street no flood damage is <br /> <br /> <br />anticipated. The Rocky Mountain Ditch crossing Lakewood Gulch <br /> <br /> <br />east of Garrison Street does not materially obstruct the flow <br /> <br /> <br />in the floodplain. The culvert under Dudley Street is too small <br />
