CHAPTER V

STAGE TWO PLAN OF DEVELOPMENT

A contract between the United States and the Colorado Division of

Wildlife would be necessary to ensure administration and maintenance of

wildlife areas and related features by that agency.

Public lands required for material source areas and cross-drainage

facilities would have to be withdrawn, and private lands required for

canal cross-drainage facilities would need to be acquired.

Relocation of Property of Others

No major relocation would be required for Stage Two construction.

Precautions would be taken during construction to minimize disturbance of

existing utilities and watercourses.

Government Highline Canal bridges

as well as lateral road crossings would be replaced if necessary; how-

ever, roadways across both the canal and laterals would remain passable

during the construction period. No structure upgrading is planned. All

fencing removed for construction purposes would be restored.
