· Birds: 437 to 445 vs. 453 · Preble's: 299 to 305 vs. 332 · Wetlands: 220 to 228 vs. 114 · It is important to note that these acreage estimates do not yet account for overlap of habitats or mitigation ratios. o The next steps for the mitigation table include: · Developing necessary information in order to assess the feasibility of the candidate site. The workgroup will need help with information on water sources, water availability, and cost. · The workgroup will identify feasible sites and move them forward in the Conceptual Mitigation Plan. · They will assess the habitat overlap and determine the mitigation ratios with the USFWS. . Rod Kuharich noted that possible mitigated habitat lands could come from open space in future developments in Highlands Ranch and Littleton- they would be mostly drainage ways. He added that another source of land could be in the unincorporated areas surrounding the cities that are managed by home owners' associations. They have to maintain a designated amount of open space. . Tom Browning said the State of Colorado maintains a right-of-way on the South Platte River downstream of Chatfield Reservoir for 6 miles (250 feet on each bank)-this land could potentially be offered for mitigation. He added that the State needs to find the best cost/benefit ratio. . Participant question: will the mitigated lands be included in the final EIS? Dan McAuliffe said that the agreements will not necessarily be in the final but wants to have the plans in place before the final draft is issued because the State will need to know how much the agreements will cost. . It was suggested by Tom Browning that the next Mitigation subcommittee meeting should before the Environmental and Recreation subcommittee meeting on August 21 st. . Coordination of recreation and environmental mitigation Following a conference call between Tetra Tech, the Corps, and Parks, on July 1 ih Tetra Tech provided the Parks with habitat maps in GIS for use by EDAW. Tetra Tech is currently analyzing the impacts to trees and vegetation and will provide this information to the Parks. There needs to be ongoing communication between Parks, EDAW and the Corps, and Tetra Tech regarding these subjects. . Corps' Investigation of Berms and Embankments Power Point slides presented by Betty Peake and Eric Laux outline the amount of ponded acres created by various scenarios on Plum Creek and the South Platte River. o Plum Creek · A single 66-foot high embankment placed near the 5,444' contour creates a ponded area of 630 acres. This is a highly unrealistic option. 2
