resetting the toilet structures; and then building an crushed aggregate ADA ramp to the toilets. Also included will be to remove and replace the concrete approach pads.

The trail head toilet at the Giant White Pine Campground will not be raised 1 foot like all the other toilets in the contract. The toilets close proximity to the parking area will not allow for an ADA ramp if the toilet were to be raised.

Seeding and mulching will be completed once the ground is reshaped and all excess excavation has been removed from project area.

Clarke Mtn Campground: Clearwater County: North Fork RD (T38N R7E Sec 34) (current structure installed in 2001). The site is located along Forest Road 250, approximately 23 miles NE of Pierce Idaho, east of French Mountain saddle.

1.3 GENERAL SITE CONDITIONS AND WEATHER

A. The elevation of the site is approximately 2,000 feet above mean sea level. The construction site experiences heavy snowfall and extremely cold temperatures, with snow on the ground typically from mid-November through April.

B. In-depth water table surveys have not been performed; however, if water is encountered during excavation, the Contractor shall perform adequate dewatering to keep the excavation free from water and dispose of the water without damage to property.
