2. This option involves two sources of fill material located at
two sites (a.) 2.5 miles west from the intersection with the
Dolores-Norwood Road and (b.) 1.6 miles east from the intersection with
the Salter Y.

The Cortez Project Archeologist will conduct a Class III survey
of the Glade Road material source areas.

H. Visual Resources

Short-term impacts from cut and fill slopes along the Ormiston
Point Road would be visible from the Dolores River, Lone Dome Road, and
Williams Draw Road. Revegetation measures would reduce these impacts
within 3 to 5 years.

SUMMARY

The preferred alternative, upgrading Forest Service and Montezuma and
Dolores County Roads, will provide a permanent access route to both the
San Juan National Forest and to McPhee Dam and Reservoir. ~afety,
maintenance, design criteria, and economic reasons were responsible for
abandoning the original plan described in the FES. Feasibility estimates
of cost for the roads were developed by Reclamation and the U.S. Forest
Service. The original plan as described in the FES was estimated to cost
approximately $20 million. The upgrading alternative is estimated to cost
approximately $8.6 million. Construction activities would be restricted
to following existing road alignments. Air and water quality would have
temporary adverse impacts during the construction. About 50 acres of veg-
etation would be lost from widening and upgrading the roads. This habitat
would be lost to area wildlife. The main concern was impacts to big game
from increased vehicle use. The proposed plan has measures to minimize
this effect. No endangered species would be affected. A "No Adverse
Effect by Reason of Data Recovery" for cultural resources has been accept-
ed by the Colorado SHPO. The project would consume gravel and f~ll
material.
