2.4 Blockage of Road by Flooding due to Removal of Vegetation within Quarry <br /> Operations Area <br /> There has been a history of flooding in the Little Turkey Creek canyon, with significant <br /> flooding in 1921, 1935, 1965, 1995, 1997, 2013 and 2015, and minor flooding in other years. <br /> In 1921 an earthen dam built near the proposed Plant location failed, flooding the lower <br /> canyon. Four times in the past 20 years portions of Little Turkey Creek Road within Section <br /> 16 have been badly damaged by floods. <br /> There are four locations on Hitch Rack Ranch within Section 16 where the ingress/egress <br /> road crosses over Little Turkey Creek, one in the proposed quarry operations area and three <br /> within the lower canyon below the proposed quarry operations area. Before Eagles Nest <br /> landowners installed culverts on the stream crossings in 2013, the water depth at the stream <br /> crossings would run above 2 feet during heavy rains - an unsafe depth to drive through. <br /> During the flooding in 2015 after the culverts were installed,the volume of water running in <br /> Little Turkey Creek exceeded the capacity of the two 30 inch culvert pipes installed at each <br /> stream crossing and caused the creek to overtop the new culverts. The black circles in Figure <br /> 8 show the locations of these four crossings. <br /> uw,Pr. <br /> 1 V ` <br /> OF Pk <br /> ' `' <br /> 4*61� <br /> Figure 8 Stream Crossings within Upper Hitch Rack Ranch <br /> There are also several sections of the road that run beside the stream in the lower canyon, <br /> only a few feet above the level of the creek bed(highlighted in black in Figure 9). There <br /> have been instances where the creek flooded over its banks and ran down portions of the <br /> road. There are other locations where side canyons within the Little Turkey Creek watershed <br /> drain across the road and down into the creek (highlighted in green in Figure 9). These <br />
