Task 1: Prepare, seed, and mulch four Outslopes and construct vegetative sediment <br /> barriers at the toe of three Outslopes. Each of the four Outslopes, comprising an <br /> aggregate of twenty three acres, will be prepared for seeding by incorporating organic <br /> materials into the Outslope surface. The slopes will then be scarified by constructing <br /> thousands of small benches per acre to allow seed a site for germination. Seed will be <br /> distributed over the scarified Outslopes, and will be covered by a spray-on mulch with <br /> tackifier. Trees will be planted in bands at three or four locations at each Outslope. The <br /> tree bands will be placed horizontally across the slope with trees planted on a tight <br /> spacing pattern within each band. The bands will be vertically separated by <br /> approximately 150 to 200 feet on the Outslope. Vegetative sediment barriers will be <br /> established near the toe of three of the Outslopes. Willow wattles will be planted where <br /> conditions permit. At other locations, trees and shrubs will be planted in alternating rows <br /> in order that a substantially dense stand of plant materials are established over time. <br /> Products: Establish a forty percent vegetative cover over a three year period the Mine <br /> Bench Outslopes in order to achieve a fifty percent reduction in sediment generation <br /> from each slope. Vegetative sediment barriers, where established, will contain fifty <br /> percent of sediment which continues to be generated from the slopes. It is estimated <br /> that the combined cover and barrier techniques can reduce iron bearing sediment <br /> generation by 8.1 tons per acre per year from each Outslope. <br /> Cost:' $ 160,457.77 <br /> Objective 2: Provide a means for public involvement and education in the revegetation <br /> effort, and in measuring the reduction of sediment and iron delivery to Coal Creek. <br /> Task 2: Using pre-established contacts at area schools and local public interest groups, <br /> provide opportunities for public participation in the project. The public will be provided <br /> with the opportunity to sample Coal and Dutch Creeks for sediment and metals, plant <br /> trees and shrubs, help measure vegetative success at the Outslopes, and help evaluate <br /> rill and gully development at the sites. The Division will conduct a yearly tour for <br /> interested persons to view the work areas. Presentations will be made to local public <br /> interest groups and schools. <br /> Products: The dissemination of information about stream quality improvement through <br /> erosion control, and providing environmental education opportunities in-high elevation <br /> conditions. <br /> Cost: $ 2,798 <br /> Objective 3: Determine the reduction of iron-bearing sediment generated from the <br /> Outslopes. <br /> Task 3: Monitoring and maintenance of the Outslopes and of the vegetative sediment <br /> barriers will occur annually for three years. Year 1 monitoring will be limited to obtaining <br /> pre-planting cover data on the Outslopes. Monitoring in Years 2 and 3 will consist of <br /> measuring plant materials at previously constructed transects at each Outslope and <br /> vegetative barrier. Should monitoring disclose that vegetative development is less than <br /> that necessary to meet the Project goals, maintenance activities will be undertaken. <br /> Maintenance will consist of such remedial activities as inter-seeding or planting <br />
