. ~ design modifications, restoration of altered habitat to previous or better quality, aggressive habitat management, land from $100 to $1,500 per acre for wildlife improvements to approximately $2,000 per linear foot to construct highway bypasses for big game. Threatened and Endangere~ Species. Populations of Harrington's penstemon, a candidate threatened or endangered plant species, could be adversely affected by construction of Eagle-Colorado Reservoir. Site- specific surveys would be required prior to project construction. Appropriate actions would be determined following biological assess- ment, as required under the Endangered Species Act to avoid impacts. The cost of the survey would be approximately $10,000. Cultural Resources. Construction of the proposed reservoir and ancillary facilities would affect the Alkali Creek bridge abutments and the Denver and Rio Grande ..Railroad which have been recommended as eligible for listing on the National Register of Historic Places. Adverse effects to these. structures would be considered significant impacts. Similarly, any adverse effects on sny of the 10 cultural sites known to exist, but which have not been evaluated for listing eligibility, would be considered a significant impact if the sites were later determined to be eligible for listing. Mitigation costs could range from $1,500 to $60,000 per site depending on the complexity of excavation or documentation of sites. Institutional Issues The institutional Issues of this project would involve agreements with the Bureau of Reclamation, the Northern Colorado Water Conservancy District, the Colorado River Water Conservation District, and many of the Colorado River water users. The project would require water rights transfer, mitigation, and permits for the reservoirs and pipelines. 23
