PART 1 – SUMMARY OF WORK

1.1 DESCRIPTION

A. The intent of this section is to provide a general outline of the work required under this contract and identify special project conditions and/or requirements. It is not intended to provide detailed specifications for materials, labor, and workmanship. These are covered in other sections of these specifications.

I. The Herman Gulch trailhead is a popular gateway for hikers, fishers, backpackers, and back country skiers. Located just east of Loveland pass (HWY 6), the trailhead is a minute off i- 70, providing easy access to trail systems on the Clear Creek Ranger District (CCRD) of the Arapaho & Roosevelt National Forests and Pawnee National Grassland. Herman Gulch sees very heavy recreation use for both the winter and summer months, and it is not uncommon for the parking lot to fill up year-round. The vault toilets at the trailhead were hit and damaged by a snowplow. The building posed a safety hazard and was removed.

Currently, there are two portable toilets to accommodate the large volume of trailhead users. The old vaults and lids need to be properly disposed so the existing excavation can be used, and a new vault toilet can be installed.

The area is generally accessible year-round given its close proximity to I-70.

1.4 SITE ACCESS
