RECLAMATION PLAN EXHIBIT E (CONT) Island Lupton Bottoms ditches have been constantly disturbed by ditch maintenance leaving only the river corridor, that will not be disturbed, with vegetation that may be considered native. The typical vegetation descriptions that have been submitted in EXHIBITS I&J-SOILS AND VEGETATION in previous permitting packets will match these agricultural uses as the crops rotate throughout the years. The EXHIBIT F-RECLAMATION PLAN MAP shows a cross section sketch of the proposed sloping plan and reclamation activities that will surround reservoirs in this plan. Under the contract with City of Aurora for the water storage reservoirs, the applicant has to turn over to Aurora, for contin- ued development, any reservoirs that have been significantly reclaimed. It has been agreed that this condition will exist once a reservoir liner has been certified by the Division of Water Resources, sloped, the surround gravel surface is complete. The change to graveling the band between the setbacks and the highwater line (or armored areas) eliminates the concerns that during Aurora' s development, any revegetated areas would be disturbed, destroying any grass planted. In the new area where mining will take place within 400 feet of the river, the bank will be 275 feet from the river bank at which point the slope into the reservoir will be backfilled and sloped. In this area, approximately 2, 000 feet will need 'h:l backfilling, and will not be left open for more than 12 months. Armoring will begin as soon as bank sloping is complete on each 1,000-ft section. This will also ensure, that if mining ceases before the resource is exhausted, only a minor amount of work would have to be done to finish reclamation on the disturbed area Armoring in the Northeast Phases #1 and #3 will progress with sloping, so approximately 2, 000 feet will need to be com- pleted at any time. No armoring will be done in the existing permit area. The BANK ARMORING PLAN is in the APPENDIX and explains how and where the armoring will be placed. LGE will be working with the Town of Ft. Lupton for direc- tions on Flood Plain development. This facility is not in an Urban Area, not near public land, or facilities where public safety is a concern so, inlet/outlet structures for private reservoirs are not needed. There are no plans to install Inlets or Outlets for the reservoirs. Those will be the responsibility of the reservoir developers. The following approved seed mix will be used to seed areas where reclamation calls for revegetation. This mix will place approximately 41.2 seeds per pound per sq-ft as prescribed by the NRCS planting guidelines. APPROVED SEED MIX Species Lbs.
