'" " ", Description of Project - cont'd. 1,700 feet of replacement will, by necessity, be installed along the river bank in the same location as that which was destroyed. Excavation and direct burial of this section of pipeline is not feasible due to the extremely rocky nature of the path which the pipeline must take. Therefore, it will be necessary to place the pipe on the surface similar to the method by which the original pipeline was laid. When the original installation was made, some 50 years ago, an abundant supply of inexpensive labor was available. As a result it was decided to neatly cover the total exposed pipeline with hand-cut stones taken from the surrounding canyon. The result was an aesthetically pleasing appearance blending the pipeline with the canyon walls. .~ It will again be necessary to treat the exposed pipe to avoid visual degradation of the Canyon's natural beauty. However, the hand-cutting and placing of thousands of stones is not now considered economically feasible. Therefore, other methods of visual screening must be found. Alternatives include: (a) suitable direct painting of the exterior of the pipe; (b) covering the pipeline with mechanically placed fill material riprapped to prevent erosion and; (c) installing pre-cast textured concrete panels to serve as a visual screen. Selection of the most suitable alternative will occur during the final design period. i_" The old hydroelectric power plant consisted of a building 30 feet wide, 60 feet long and 18 feet high, housing three 400 Horsepower horizontal hydroelectric generators rated at approximately 300 KW each. The building and generators were totally destroyed and no portion is re-useable. lO'_" The new plant will be located approximately 60 feet southwest of the old plant, astride the existing penstock which was not damaged by the flood. By moving the plant south- west it will be possible to locate it out of the 100 year floodway due to the higher elevation at the new location. The site is in the City of Loveland's picnic area known as Viestanz-Smith Mountain Park. ~ Based on modern technology the replacement of the three former generating units will consist of either one 900 KW vertical turbine generator, or two 450 KW vertical units. In either case the resulting building size will be significantly less than the old plant. The building will consist of concrete walls faced with natural stone to harmonize with the existing recreation building located approximately 300 feet north of the new plant. Par- ticular caution will be exercised during excavations at the dam and power plant sites to be alert for archaeological remains resulting from the flood. If remains are uncovered, ex- cavation will be halted and the State Archaeologists Office as well as cognizant local officials will be notified irnmediately. r, ,.., :~~ ~ ., 10
