RIVERCITY (b) Post-Mining Land Use Comparison The post-mining land use of open water and grassland is compatible with surrounding agricultural, recreational, and open space uses along the Colorado River corridor. The proposed pond and revegetated upland areas will complement the Riverfront Trail system and provide habitat values consistent with local open space plans. The plan is consistent with Mesa County's adopted land use policies encouraging reclamation of mined lands to beneficial open space and recreation uses. (c) Compliance with Section 3.1 Requirements The reclamation plan will comply with Rule 3.1 performance standards by providing stable slopes, erosion control, protection of water resources, and establishment of self- sustaining vegetation. Final grades will maintain positive drainage toward the central pond or existing undisturbed drainageways. Topsoil will be salvaged, stockpiled, and reapplied to support revegetation. Disturbed areas will be stabilized promptly to minimize erosion. (d) Topsoil, Grading, and Revegetation The upper six inches of topsoil will be salvaged prior to disturbance and stored in berms for later use. Upon reclamation, topsoil will be redistributed evenly over graded surfaces to a minimum depth of 6 inches, with localized ranges up to 12 inches depending on availability. All slopes will be graded to 3:1 or flatter to ensure long-term stability. The excavation will be graded to form an 11.5-acre pond in the center of the site, with upland areas graded to blend with existing terrain. Disturbed areas will be seeded with the Mesa County-approved reclamation mix at the following rates (PLS/acre): o Western Wheatgrass — 8.0 Ibs o Smooth Brome —6.5 Ibs o Intermediate Wheatgrass — 10.0 Ibs o Perennial Rye —4.0 Ibs Mulch and tackifier will be applied as necessary to promote germination and control erosion. (e) Reclamation Schedule Reclamation will be progressive and tied to mining phases rather than calendar years: • During Mining: Completed berms and stockpiles to be seeded if inactive for more than one year. Progressive grading and seeding of completed mining phases where practicable. • Final 2 Years (Stockpile Depletion): Redistribution of topsoil, grading of pond and uplands, and seeding of upland areas. • Completion: A 10-foot-wide concrete trail will be constructed connecting the site to the Riverfront Trail.
