Reveoetation All disturbed surface areas above water levels will be topsoiled and drill-seeded for final reclamation with the seed mixes shown in Tables E-1 ). If use of a grass drill is not possible, seed broadcasting will occur at double the seeding rate (per NRCS recommendations). Maintenance Mowing in each phase will be performed for at least 2 years following seeding to help establish regenerating stands of grasses and to control weed infestation. Seeded areas may be mulched with straw or hay mulch, if needed. Fertilizer will be applied to areas of the site where poor nutrient availability is indicated by a failure of seed to become established. Weed Control Plan Noxious weeds will be managed in accordance with the Colorado Noxious Weed Management Act and Chapter 15, Article I of the Weld County Code. The Code recommends Cultural, Mechanical, Biological, and Chemical methods of control for each of these species. Nine weed species are designated for management by the County Code and are listed below (not all of which are found on the subject site): • Leafy Spurge (Euphorbia esula) • Canada Thistle (Cirsium arvense) • Musk Thistle (Carduus nutans) • Scotch Thistle (Onopordum acanthium) • Field Bindweed (Convolvolus arvensis) • Russian Knapweed (Acroptilon repens) • Diffuse Knapweed (Centaurea diffusa) • Spotted Knapweed (Centaurea maculosa) • Dalmatian Toadflax (Linaria dalmatica) In all cases, the first control method for each potential weed will be mechanical. Chemical methods will be employed if mechanical methods alone are insufficient. If these two methods are ineffective, the Applicant will consult with the Weld County Weed Manager to determine the next most effective method.
