About this file
This document is a set of design and construction drawings for the Soap Creek Campground Streambank Rehabilitation project located within the Grand Mesa, Uncompahgre, and Gunnison National Forests under the Gunnison Ranger District, managed by the USDA Forest Service, Rocky Mountain Region (R02).
The project encompasses streambank stabilization and restoration work along approximately 140 linear feet of stream channel. Key construction activities include: bank regrading at a 2:1 horizontal-to-vertical slope with riprap placement (minimum 1-foot thickness, FP-24 Class 5 gradation with D₁₅ = 8 inches, D₅₀ = 10 inches, D_max = 15 inches); installation of one stream barb structure (43 feet total length, 8-foot embedded length, 35-foot weir length, constructed of FP-24 Class 2 stone with D_min = 12 inches, D₅₀ = 16 inches, D_max = 32 inches); placement of multiple rootwad structures (3-4 foot diameter, 8-10 foot footer logs, minimum 8 feet embedment depth); construction of three access points using large-diameter boulders as steps (3-4 feet wide, no greater than 8 feet in height); and willow revegetation using both plugs (planted above bankfull width) and cuttings (planted on slopes and sediment wedges). The contractor must hire a specialized subcontractor for native plant installation. All construction must occur outside the wetted channel except during stream barb construction, with tracking pads and mud mats required for equipment access. The project includes detailed cross-sectional survey data, longitudinal stream profile information, and specifications for all structural elements and materials.

HEIGHT AND NEWLY DELINEATED BANK, THEREFORE, SHALL VARY.
12. RECONSTRUCTED BANK SHALL BE TAPERED BACK INTO EXISTING BANK AT US AND DS TIE-IN POINTS AS SHOWN. LENGTH OF TRANSITION ZONE SHALL BE NO LESS THAN TEN FEET (101 AND NO GREATER THAN TWENTY FEET (20').
13. CONTRACTOR SHALL TAKE CARE NOT TO DISTURB OR REGRADE EXISTING STREAMBED WITHIN BANKFULL ZONES, EXCEPT WHERE NEEDED TO ACHIEVE SPECIFIED EMBEDMENT DEPTHS OF STREAMBANK REINFORCEMENT AND STREAM BARB. IF STREAMBED ELEVATION IS DISTURBED DURING CONSTRUCTION ACTIVITIES, IT SHALL BE RETURNED, AS CLOSELY AS POSSIBLE, TO ITS ORIGINAL CONDITION.
