further into the mountainside. Because of the steepness of the terrain, the contractor will have to deal with the need to scale the loose material above the ditch and provide protection for his workers and equipment along the ditch itself. This alternative would allow the ditch to operate normally through the high springtime runoff period without disruption. The third pipe can be installed while the ditch is operating without disturbing normal operations, with the exception of a two week period near the end of construction. At that time the flow in the ditch will have dropped to a small fraction of its peak. The contractor will then build the head walls at either end of the new pipe and put the new pipe in service. 4. Plate Arch wipe. The last alternative is the removal and replacement of the two pipes installed in 2003 with a larger, single pre-fabricated corrugated, galvanized steel plate arch pipe. The existing pipes would be removed and the new plate arch pipe would be assembled on site in the same location. The plate arch pipe installation would not require widening of the existing excavation or the rock bench upon which the existing pipes rest. The advantages of this installation include the removal of the inherent obstruction in the center of the ditch which exists with multiple pipes versus a single pipe, reducing the chance of floating trees or other debris hanging up at the mouth (inlet) of the pipe(s). This alternative is somewhat more expensive than Alternative 3, we estimate, and will cause a more significant disruption in 2009 ditch operation, also compared to Alternative 3. It may be necessary to enter into an exchange agreement with NCWCD to avoid losing valuable water during the 2009 construction season in order to deal with runoff water foregone during construction, if such an agreement is possible at all. Kluver Reservoir Outlet/Travis Road Embankment Project: The Kluver Reservoir Outlet/Travis Road project is located in Larimer County at the intersection of Travis Road, the inlet/outlet from Kluver Lake and the inlet to Reservoir #4. The site is accessible by turning east from North Shields Ave. on Travis Road in North Fort Collins, Colorado. The site is in the northwest quarter of Sec. 23, T8N, R69W of the 6th P.M. Reservoir #4 and Kluver Reservoir are filled by a ditch which runs south from the outlet of Reservoir #3. The ditch from Reservoir #3 feeds into another common ditch lying east and west between Kluver Reservoir and Reservoir #4. That common ditch serves as inlet for Reservoir #4 as well as both inlet and outlet for Kluver Reservoir. Travis Road runs east from Shields Avenue along the southern shore of Kluver Reservoir then turns north and lies between Kluver Reservoir and Reservoir #4. Travis Road is a Larimer County road providing the sole access to homes along the north and east shore of Kluver Reservoir. Travis Road was constructed over the common inlet/outlet ditch which runs between Kluver Reservoir and Reservoir #4 in the 1950's. The road embankment has concrete retaining walls on either side at the point the road crosses the common inlet/outlet ditch. There are two buried CMP's in and under the road embankment to convey water back and forth between the reservoirs and head gates in the retaining walls to divide and control the flows. Those concrete retaining walls have failed or are about to fail, and the road surface has been partially eroded and undermined. The Larimer County Road and Bridge Department has closed and abandoned the road and constructed a temporary by-pass across the inlet/outlet ditch pending a final resolution.
