Coulson Ezcavating Company, Inc. - Bonser Gravel Pit
<br />Ezbibit E -Reclamation Plan
<br />completed as the quality soils and availability of water should facilitate the rapid establishment of
<br />perennial grasses.
<br />Following revegetation, weed management strategies will be implemented to facilitate and
<br />achieve native grassland. The strategies will include an aggressive mowing program to prevent
<br />the growth and establishment of weeds, specifically, the eight noxious weeds recognized by
<br />Lorimer County: Canada thistle (Cirsium arvense), Dalmation toadflax (Linaria dalmatica),
<br />diffuse knapweed (Centaurea d~a), leafy spurge (Euphorbia esula), musk thistle (Carduus
<br />natans), Russian knapweed (Centaurea repens), spotted knapweed (Centaurea maculosa), and
<br />Yellow toadflax (Linaria vulgaris) as mandated by Colorado State Law (35-S.SCRS 1990, 1996).
<br />Total Cost
<br />In summary, the total costs for this reclamation plan include:
<br />• Disking $420 to $560 (for 7 ac)
<br />• Seeding $4,040 to $5,655 (for 7 ac)
<br />• Fertilizing $962 (for 6 ac)
<br />Please refer to Exhibit L, Reclamation Costs for further details.
<br />Alternative Reclamation Plan
<br />There is no alternative reclamation plan.
