SOIL PREPARATION: SOIL TEST: SOIL TESTING WILL DETERMINE WHETHER THE SOIL PH AND NUTRIENT (PHOSPHORUS, POTASSIUM, CALCIUM AND MAGNESIUM) LEVELS ARE IN A RANGE THAT FAVOR TURFGRASS GROWTH. THE SOIL TEST REPORT WILL INDICATE NEEDED AMOUNTS OF FERTILIZER AND/OR LIME. CLEAN AND ROUGH GRADE: REMOVE ALL DEBRIS FROM THE LOCATION TO BE PLANTED. THIS INCLUDES ROCKS, BOTTLES, LARGE ROOTS AND OLD TREE TRUNKS. IF EXTENSIVE GRADING IS NEEDED, REMOVE THE TOPSOIL AND STOCKPILE IT FOR REPLACEMENT AFTER THE ROUGH GRADE IS ESTABLISHED. THE SUBSURFACE MAY BECOME COMPACTED DURING ROUGH GRADING, ESPECIALLY IF THE GROUND IS WET. THIS COMPACTED LAYER MUST BE BROKEN UP. A SPRING -TOOTH HARROW WORKS WELL ON LIGHTLY COMPACTED SOILS; A SMALL ROTOTILLER MAY BE NEEDED FOR MORE HEAVILY COMPACTED SITES. DEEP TILLAGE: ROTOTILLING LOOSENS COMPACTED SOIL AND IMPROVES THE SPEED AND DEPTH OF ROOTING. A TRACTOR -MOUNTED OR SELF-PROPELLED TILLER WILL ADEQUATELY TILL THE SOIL. TAKE CARE NOT TO DESTROY THE EXISTING TREES IN THE LAWN. CUTTING TOO MANY TREE ROOTS DURING SOIL TILLAGE CAN SEVERELY DAMAGE OR KILL A TREE. TREES CAN ALSO BE SUFFOCATED BY DEEPLY COVERING THE ROOTS WITH SOIL. IF ADDITIONAL SOIL IS NECESSARY AT A TREE BASE, CONSTRUCT A "TREE WELL." REPLACE THE TOPSOIL: ONCE THE SUBSURFACE IS ESTABLISHED, RETURN THE TOPSOIL AND SPREAD UNIFORMLY OVER THE ENTIRE AREA. ALLOW FOR AT LEAST 6 TO 8 INCHES OF DEPTH AFTER THE SOIL HAS SETTLED. THIS MEANS PLACING ABOUT 8 TO 10 INCHES OF TOPSOIL OVER THE SUBSURFACE. IMPROVE THE SOIL BY ADDING ORGANIC MATTER.

GINE G BREC, P.A. 29 January 2018 Justin Church, PE Principal Engineer CC Hayes Stream Restoration General Information The CC Hayes Stream Restoration project is a proposed priority two restoration of two degraded unnamed tributaries to Purlear Creek in Wilkes County, NC. The primary goal of the projects is to mitigate channel instability and stream bank erosion by modifying the dimension, pattern, and profile of the channel to create floodplain connectivity with a re-established riparian buffer protected by livestock exclusion fencing. The project has the added benefit of being directly upstream of a completed mitigation project with a well-developed fenced buffer. The environmental uplift created by that restoration will be extended up valley by this project. 2.0 Design Considerations The restoration plan for both channels was guided by natural channel design methodologies. Reference reach data was taken from a collection developed by the North Carolina State University Stream Restoration Program. 2.1 Unnamed Tributary 1 Bankfull cross sectional area was selected as 2.5 f t2 with a bankfull width of 5.5 ft based on field observations and regional curve data for the area. A design W/D ratio of 12 was selected to match field observations and maintain a sufficiently narrow channel to transport sediment while maintaining the bankfull depth at an elevation that can be supported by early onset vegetation. Pool spacing is a primary design consideration given the channel gradient of approximately 3.1%. Based on reference reach data and information published by Wildland Hydrology (see figure below), pool to pool spacing was set in the 3Wbkf ± 0.25Wbkf. This pool frequency matches the valley and keeps the riffles sufficiently steep to maintain pool scour and sediment transport. 0 Y - 8.4"513;[•"`' 5 FF = Ckma & 3 2 • 8 1 • 0 0 1 2 3 4 S 0 7 8 O Channel Supe 1% Figure 1 - Rosgen Pool to Pool Spacing Relationship BREC, P.A.

A design W/D ratio of 16 was selected to match field observations and maintain a sufficiently narrow channel to transport sediment while maintaining the bankfull depth at an elevation that can be supported by early onset vegetation. The valley slope for this tributary is approximately 1.45%, which is more conducive to a meandering design. Design belt width and meander lengths were taken from reference data.

Obtain all necessary permits from regulatory authorities and maintain copies on site at all times. 2. Stage all construction materials on site including seed, matting, boulders, and logs prior to construction. 3. Install temporary fence to protect work area from livestock. 4. Stake -out design alignment. 5. Begin construction at the upstream station. Each day's channel excavation must be limited to what can be stabilized with structures, seed, straw, and/or matting at the end of the day's work. 6. Stabilize each day's work with temporary or permanent seed per the specified seed schedule and straw or matting. 7. When construction is complete, install permanent livestock exclusion fencing. 8. After permanent fencing is in place, install permanent riparian vegetation. BREC, P.A. CC Hayes Stream Restoration
