Run-off from the portal and office shop complex flows across the parking lot to one of three grated drains along the west edge of the portal bench. There are two 6-inch diameter drains and one 4-inch diameter. The two six inch drains combine into a single six inch pipe at the base of the retaining wall. Flow from the single 6-inch pipe is routed over the steep slope below the retaining wall in a six inch flexible ADS pipe. Flow from the 4-inch grated drain and the 4 inch drain pipe near the shop join below the retaining wall. The combined flow in the 4-inch pipe is routed over the steep slope below the retaining wall in a 6-inch culvert/flexible ADS pipe. A 6 inch diameter culvert/flexible pipe below the retaining wall collects drainage from a small upland area, portions of Light Use Road No. 1 and a portion of the top of the RSRDA. There is a low spot on the top of the RSRDA that does not flow to the above mentioned pipe. A 6 inch diameter flexible pile will be utilized to collect water from this low spot and convey the water down to the top terrace drain. During 2002 an upper diversion ditch was installed to divert runoff around RSRDA. Pond 9 collects run-off from this diversion ditch. Runoff from portions of the lower west face of the pile are directed to the Pond 9 by a ditch along the toe of the pile. Ute Water Conservancy District installed a water supply pipe line from their plant located in Section 2, T11 S, R98W to Island Acres State Park which is located in Section 26, T10S, R98W in 1991. Of the routes investigated, their preference was to install the line in a northwesterly direction to Interstate 70 and follow the highway from there. The line was installed along this route which crosses the Roadside refuse pile skirting the south side. See Exhibit 6A & 66 for the location where the line crosses the refuse pile. 13-12 (Rev. 09/04)
