11, As discussed on-site, we recommend that the mature cottonwoods along the South Platte River should be protected. They provide excellent- wildlife habitat and berm stabilization. Please use the aerial photo/map to delineate the anticipated pit boundaries relative to the existing trees. The boundaries should be designed to avoid as many of the trees as possible. 72, The proposed gas pipeline berms and the proposed method of excavating in and near the pipelines may not be adequate to protect the lines from damage. Sma11 berms adjacent to relatively large lakes can be easily eroded by wave action. We will recommend approval of the proposed configuration only if we receive a copy of a specific agreement between Coors and the operator. Alternative plans may be necessary of such an agreement is not obtained. 13. As with all river pits, we need to be assured that the proposed pit will not create hazards to off-site structures or adjacent properties during flood conditions, We will coordinate our requirements with those of the Urban Drainage and Flood Control District (UDFCD) so that the operator is not penalized by double regulation. Mr, Ben Urbonas (UDFCD) is reviewing your proposal and we expect his comments shortly. It is our hope that we can incorporate specific berm stabilization requirements for the final approval; however, if this is not possible, then we will recommend a general stipulation regarding compliance with UDFCD requirements. In the absence of specific design plans, we will also recommend that the operator maintain a 400 foot undisturbed setback. This would allow initial application approval and the operator could revise the plan as more detailed designs are available. Exhibit E - Reclamation Plan 1. As previously mentioned, we recommend that the operator redistribute topsoil to a minimum depth of 10 to 12 inches. The soil should be readily available and such depths should enhance revegetation success, and thus accelerate financial warranty release. Also, the end use at the plant area is agriculture, so deeper topsoil redistribution is appropriate. A range of 12-16" should be considered. Please provide specific redistribution depths. The pit areas will be used as wildlife habitat. We will be discussing specific recommendations with the Division of Wildlife, so that final reclamation provides an optimal wildlife habitat configuration. Such suggestions may include expansion of shallow or shelf area, greater shoreline irregularity, etc., we will forward any new recommendations as soon as they become available. 3. Please provide more specific details regarding tree and shrub establishment. Include planting densities and anticipated survial rates. Also, please consider attempting to reestablish cottonwoods to compensate for those lost to mining. Perhaps some smaller trees can be transplanted from other areas of the property.
