<br />investigate and recommend a course of action to alleviate flood problems at Holly. Subsequent <br />Corps investigations and studies resulted in the construction of the Holly Flood Control Project <br />(Project) which was completed February 13, 1981.. The Project's general features are shown on <br />Figure I (Plate 2, titled General Plan, dated April 1979 from the Corps' April 1979 Plans for <br />Construction of Levee and Related Facilities). <br /> <br />The Project consists of the following features: <br /> <br />· A left bank levee along Wild Horse Creek beginning at a high point north of the Town <br />extending south along the left bank of Wild Horse Creek to its confluence <br />with the Arkansas River where it joins the levee along the Arkansas River; <br /> <br />· A left bank levee along the Arkansas River extending easterly from the confluence <br />with Wild Horse Creek following the north bank of the Arkansas River to a point about <br />I mile east of the State Highway 89 bridge across the Arkansas River; <br /> <br />· Stop log closure structures where U.S. Highway 50 and where the AT&SF Railroad <br />cross the levee west of the Town; <br /> <br />· Elevated road ramps where State Highway 89 crosses th(: levee south of Town and <br />where the County Road crosses the leve(: west of the Town; <br /> <br />· Riprap protection on selected sections of the levee; <br /> <br />· Interior drainage facilities including two 30 inch gravity outlet structures through the <br />levee with flap gates; <br /> <br />Total levee length is 22,160 feet consisting of 12,000 feet along Wild Horse Creek and <br />10,160 feet along the Arkansas River. The levee along the Arkansas River extends 5400 feet east <br />of the State Highway 89 bridge across the Arkansas River. This is considered a sufficient <br />distance to prevent backwater from entering the town behind the levee. The top width is 12 feet <br />which permits access for maintenance. Riverside slope is 3 horizontal to I vertical and lands ide <br />slope is 2.5 horizontal to I vertical. <br /> <br />Levee height along Wild Horse Creek from its north beginning point to the AT &SF <br />Railroad bridge west of Holly (9735 feet) provides 4 teet of freeboard above the project design <br />flood water surface. Levee height between the railroad bridge and State Highway 89 south of <br />Holly (7013 feet) has 5 feet of freeboard above the project design flood water surface to provide <br />an additional I I foot of protection from Two Butte Creek flows entering from the south <br />perpendicular to the levee. Levee height east of State Highway 89 (5412 feet) provides 3 feet <br />of freeboard above the project design flood water surface. This was considered adequate to <br />contain the flood of record which was larger than. the project design flood. <br /> <br />Riprap bank protection was placed at two loeations on the levees.
