These <br />included the Corps of Engineers, E.P.A. and State Historic Preservation. As noted above, <br />the Corps and E.P.A. supported the project and supplied preferred low,flow channel design <br />concepts. The State Historic Preservation Office noted placer-related low-flow channel <br />design concepts but were willing to coordinate with E.P.A. and City of Black Hawk design <br />standards. <br /> <br />Colorado Department of Transportation was contacted to discuss construction constraints and <br />joint benefit of the project. The Colorado Department of Heath and Environment is <br />interested in coordinating their "dirty" water (Super Fund) project with the construction of the <br />Chunnel. The Colorado Water Conservation Board was contacted relatively late in the <br />project but is supportive of the project and is assisting in funding. Larry Lang of CWCB has <br />indicated his confidence in the concept and design. <br /> <br />A relationship has been established with all of the reviewing and regulatory /lgencies involved <br />with the project. The regulators /lgree the most difficult existing conditions related to <br />water/bed material quality and wetlands will be improved by the 'project. <br /> <br />Technical <br /> <br />Mapping <br /> <br />Existing mapping data has been assembled by Futura for the length of the project. They <br />include ADG mapping completed for the City and Colorado Department of Transportation <br />(COOT) survey. ADG mapping is available on disk. roOT mapping has already been used <br />in analyzing property boundaries. . <br /> <br />Futura has a negotiated with Landmark Mapping for updating buildings and local topography <br />along the Chunnel alignment. In general, the North aear Creek channel has changed little <br />since the 1992 topography which has been used to analyze design thus far. Futura also has <br />completed ground survey in the vicinity of the transition structure (near Mill Site 28) and <br />Mill Sites 29 through 32 which is directly applicable to preliminary and final design. <br /> <br />Ownership/Right-of- Way <br /> <br />Futura has completed boundary survey and ownership through 25% of the Cbunnellength. <br />In addition to COOT survey we have ADG main street right-of-way information and our own <br />surveys and record research. Ownership and topographic mapping are currently being <br />overlayed for production of right-of-way documents. <br />
