4.6.6.Placement will require cabling of installed logs and rootwads to snags, boulders and deadman anchors. Cables must be installed on bare wood surfaces, double wrapped and pulled tight as shown in the plans. 4.7. To facilitate efficient movement of logs,the Contractor shall provide a track excavator with a hydraulic thumb attachment. 4.8. Large wood will be placed and ballasted according the Drawings and the direction of the Engineer. Ballast will consist of burial and embedment into soil, backfill with soil, boulder placement, and cabling to other logs, buried Snags and buried Deadman anchors. S. PLANTING 5.1. Planting of native grass,forb and shrub species will take place above the predetermined lower limit for vegetation, in areas designated in the plans. A mixture of species with varying moisture tolerances is recommended to ensure survival. 5.2. The species lists contain plants native to the project area and that thrive in riparian environments. These lists may change based on availability of plant materials. Additional native species may be added, but must be approved by the project owner. 5.3. Native grasses and forbs will be planted from seeds hand or mechanically sown and incorporated at a density of 30-50 pounds per acre.The native grass community is designed for immediate erosion control in all excavated areas, and is considered temporary until natural succession occurs. 5.4. Native floodplain trees and shrubs in the immediate riparian zone will be planted as potted stock, and will be installed using a clumped planting plan based on numbers calculated from an 8 ft grid pattern. 5.5. Upland trees and shrubs will be installed following random placement based on a clumped plan calculated from a 25 ft grid density. 6. MEASUREMENT AND PAYMENT 6.1.
