THE CONTRACTOR SHALL PLANT WOODY VEGETATION AND LIVE STAKES, ACCORDING TO PLANTING DETAILS AND SPECIFICATIONS. THEY SHOULD COMPLETE THE REFORESTATION (BARE ROOT PLANTING) PHASE OF THE PROJECT AND APPLY PERMANENT SEEDING AT THE APPROPRIATE TIME OF THE YEAR. 20. THE CONTRACTOR SHALL ENSURE THAT THE SITE IS FREE OF TRASH AND LEFTOVER CONSTRUCTION MATERIALS BEFORE MOVING ON TO A NEW SECTION OF CHANNEL. UT To LITTLE FISHER RIVER SURRY COUNTY, NC GENERAL NOTES PREPARED IN THE OFFICE OF: ECOSYSTEM PLANNING & RESTORATION 1 150 SE MAYNARD RD, SUITE 140 RALEIGH, NC 2751 1 LICENSE # P-1 182 PROJECT ENGINEER PROGRESS DRAWING FOR REVIEW PURPOSES ONLY DO NOT USE FOR CONSTRUCTION PHASE 1 – ENTIRE PROJECT MOBILIZATION AND GENERAL EROSION CONTROL 1. Limits of Disturbance is 9.2 acres. 2. Identify and locate staging areas, stockpile areas, construction entrances, stream crossings required for construction access; limits of silt fencing, and construction access and haul roads as shown on plans. 3. Install construction entrance along Haystack Road. 4. Install stream crossings required for construction access. 5. Stockpile materials in designated areas. 6. Install silt fencing as directed by the Engineer. Silt fencing will be installed along the downslope/stream side limits of all staging and stockpile areas so that any washed sediment is trapped. 7. Upon the completion of phase 1, the Contractor shall schedule an inspection of the phase by the Engineer. The Contractor must have approval from the Engineer that the phase has been completed to satisfactory standards before beginning another phase. 8. Emergency Contact for Erosion and Sedimentation Control is: Jake Byers, PE Ecosystem Planning and Restoration 828-348-8580 NOTE: Each phase will be completed prior to beginning work on another phase. Upon the completion of each phase, the Contractor shall schedule an inspection of the phase by the Engineer. The Contractor must have approval from the Engineer that the phase has been completed to satisfactory standards before beginning another phase. All excavated soil materials not utilized will be stockpiled and maintained in the designated stockpile areas. If any excavated soil materials need to be, are specified to, and actually are disposed of off-site by the Contractor, the Contractor is responsible for disposal of such soil materials in a permitted area, as well as for providing and implementing an erosion and sedimentation control plan and permit, or any other required permit(s), for the location(s) off site where such materials are disposed. PHASE 3 – ENTIRE PROJECT DEMOBILIZATION AND PLANTING 1. Complete remaining minor grading and site planting preparation work, including ripping and/or disking, as specified in the project specifications. 2. All remaining disturbed areas, including areas that have been ripped and/or disked are to be amended, seeded, matted and/or mulched according to the project specifications and at a minimum within 14 days of disturbance. 3. Complete all remaining proposed permanent vegetation planting per the plans and project specifications. 4. Remove and dispose of all trash, metal, and debris from the site according to local, state and federal regulations. 5. restore construction access roads, staging areas, and stockpile areas. Immediately regrade, replace topsoil, and seed, amend, and mulch as specified in the project specifications. Silt fence shall be removed once the site has been stabilized with vegetation. PHASE 2 – UT TO LITTLE FISHER STATION 10+00 to 39+87 CHANNEL RESTORATION IN PLACE 1. Perform construction staking. 2. The proposed channel follows the alignment of the existing channel throughout this work area. All work shall be conducted in the dry. No more channel can be opened or disturbed than can be completed and stabilized that same day. A pump-around operation will be required along this work area. Begin pump-around operation at upstream end of each section that can be completed in the same work day. Install an impervious dike at upstream and downstream ends of the proposed sections in order to isolate all work from stream flow. Pump-around operation should be conducted in accordance with the typical pump-around operation detail as shown on the plans. Turbid water between impervious dikes must be pumped with a separate pump into a special stilling basin to be discharged downstream of the impervious dikes in accordance with the typical pump-around operation detail as shown on the plans. 3. Perform required removal and treatment of any exotic vegetation within and adjacent to the specified reach limits. All required removal and treatment (initial treatment) of exotic vegetation should be completed prior to proceeding with the remaining activities in this phase. 4. Perform required clearing and grubbing. Segregate and stockpile topsoil and other soil material in accordance with the project specifications. 5. Construction work can begin at either end of the project area at the discretion of the contractor. proceed with floodplain, channel and in-stream structure construction as specified on the plans. All usable existing gravel and cobble in the existing channel shall be excavated and utilized in the proposed channel prior to filling. 6. Construct connections with unnamed tributaries (UT2, UT3, and UT4) in conjunction with construction on UT to Little Fisher. 7. Perform all topsoil replacement, vegetation transplanting, seeding (temporary and permanent), soil amendment, mulching, and installation of all coir fiber matting as specified on the plans and the project specifications. Associated disturbed stream banks will have temporary and permanent seed, soil amendments, mulch, and coir fiber matting applied to them as work progresses and by the end of each day. Coir fiber matting will be installed on top of the seeded, amended, and mulched stream banks according to the project specifications. 8. Remove and dispose of all unused vegetation and excavated materials. 9. All remaining disturbed areas are to be amended, seeded, mulched and matted according to the project plans and specifications and at a minimum within 14 days of disturbance. 10. Upon the completion of phase 2, the Contractor shall schedule an inspection of the phase by the Engineer. The Contractor must have approval from the Engineer that the phase has been completed to satisfactory standards before beginning another phase.
