The Stairs penstock is a particularly well-preserved and visible (e xce pt for about the last 150 ft.) example of a late-1890s penstock. The Stairs Station penstock maintains integrity of design, setting, workmanship, location, feeling, materials, and association. The penstock is a contributing feature of the historic district. 6. Standpipe At the top of the penstock is a steel standpipe, built ln 1939. The standpipe structure rests on a concrete block which is located at the point where the steel pipeline meets the top of the penstock. The top half of the stand p ipe was recently added by Utah Power and Light . Because of t hi s recent additi o n, the standpipe no longer retains integrity of materials and design. It does not contribute to the Stairs Station Historic District . 7,8. Ancillary Structures Other structures at the Stairs Stat ion include a small, concrete block outhouse with a flat metal-covered roof and a wooden door which sits just north of the powerhouse. East of the powerhouse, is a rock-terraced ope ning which e x tends into the hillside. Thls was the original oil shed (n o. 7), but is currently unused because it has partially collapsed. Despite the collapse the oil shed from the outside appears intact. The oil shed still retains overall integr i ty of location, design, materials, workmanship, setting, feeling, and association. It is a contributing element of the historic district. Similar rock terracing as was used for the oil shed acts as riprap along the highway embankment just north of the powerhouse. Adjacent to the powerhouse and crossing Big Cottonwood Creek is a modern bridge (no. 8) which provides access to the UP&L picnic grounds. This is a modern structure made of steel with a wood deck and concrete abutments. It is a non-contributing feature of the historic district. |
