George Worsley Vice-Chancellor for Finance and Business North Carolina State University Box 7201 Raleigh, NC 27695-7201 DATE ATTACHMENT A: Description of Proposed Work The project includes the restoration of approximately 700 linear feet of stream channel in the Yates Mill Pond watershed. The construction will include the excavation of topsoil and sod, construction of a new channel on the floodplain, and placement of fill material into the old channel to partially fill the channel and create a series of small wetlands and ponds. Erosion control matting, transplants, mulching, and seeding will be used to stabilize graded areas. Sod transplants will be used to stabilize the banks of the new constructed channel. Rock vanes, log vanes, and root wads will be placed in the new channel and at the toe of the streambanks for bank stabilization and habitat improvement. One culverted stream crossing will be installed, and 2 existing culverts will be removed. ko,6 ??ee?er 00'a UNITED STATES ?- DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY '08'08 78°45' 17040o0m.E. /z.4 All 1 1/06 /01 42'30" 31, •?

Streambank Restoration Cc 8-6i footer log INSTREAM PRACTICES Grade Control Measures Rock, wood, earth, and other material structures placed across the channel and anchored in the streambanks to provide a "hard point" in the streambed that resists the erosion forces of the degradational zone, and/or to reduce the upstream energy slope to prevent bed scour. Appendix A Applications and Effectiveness • if a stable channel bed is essential to the design, grade control should be considered as a first step before any restoration measures are imple- mented (if degradational processes exist in channel system). • Used to stop headcutting in degrading channels. • Used to build bed of incised stream to higher elevation. • Can improve bank stability in an incised channel by reducing bank heights. • Man-made scour holes downstream of strictures can provide improved aquatic habitat. • Upstream pool areas created by structures provide increased low water depths for aquatic habitat. • Potential to become low flow migration barrier. • -Can be designed to allow fish passage. • If significant filling occurs upstream of structure, then downstream channel degradation may result. • Upstream sediment deposition may cause increased meandering tendencies. • Siting of structures is critical component of design process, including soil mechanics and geotechnical engineering. • Design of grade control structures should be accomplished by an experi- enced river engineer. For More Information • Consult the following references: Nos. 1, 4, 5, 6, 7, 12, 17, 18, 25, 26, 31, 37, 40, 63, 66, 84.

Applications and Effectiveness • Most successful on streambanks where moderate erosion and channel migration are anticipated. • Reinforcement at the toe of the embankment is often needed. • Enhances conditions for colonization of native species. • Used in conjunction with other protective practices where flow velocities exceed the tolerance range for available plants, and where erosion occurs below base flows. • Streambank soil materials, probable groundwater fluctuation, and bank loading conditions are factors for determining appropriate slope condi- tions. • Slope stability analyses are recommended. For More Information • Consult the following references: nos. 11, 1.1, 56, 61, 65, 67, 68, 77, 79. Branch Packing Alternate layers of live branches and compacted backfill which stabilize and revegetate slumps and holes in streambanks. A-10 Applications and Effectiveness • Commonly used where patches of streambank have been scoured out or have slumped leaving a void. • Appropriate after stresses causing the slump have been removed. • Less commonly used on eroded slopes where excavation is required to install the branches. • Produces a filter barrier that prevents erosion and scouring from streambank or overbank flows. • Rapidly establishes a vegetated streambank. • Enhances conditions for colonization of native species. • Provides immediate soil reinforcement. • Live branches serve as tensile inclusions for reinforcement once installed. • Typically not effective in slump areas greater than four feet deep or four feet wide. For More Information Consult the following references: Nos. 14, 21, 34, 79, 81. Stream corridor L' s+..n Co: r?c?>c ?Zi4, ?'?-?q (USM , Mc?) STREAMBANK TREATMENT Log, Rootwad, and Boulder Revetments Boulders and logs with root masses attached placed in and on streambanks to provide streambank erosion, trap sediment, and improve habitat diversity. Applications and Effectiveness • Will tolerate high boundary shear stress if logs and rootwads are well anchored. • Suited to streams where fish habitat deficiencies exist. • Should, where appropriate, be used with soil bioengineering systems and vegetative plantings to stabilize the upper bank and ensure a regenerative source of streambank vegetation. • Will enhance diversity in riparian areas when used with soil bioengineer- ing systems. • Will have limited life depending on climate and tree species used. Some species, such as cottonwood or willow, often sprout and accelerate colonization. • Might need eventual replacement if colonization does not take place or soil bioengineering systems are not used. • Use of native materials can sequester sediment and woody debris, restore streambanks in high velocity streams, and improve fish rearing and spawning habitat. • Site must be accessible to heavy equipment. • Materials might not be readily available at some locations. • Can create local scour and erosion. • Can be expensive. For More Information • Consult the following references: Nos. 11, 34, 77. Riprap Applicatio s .and Effectiveness • Car)-be vegetated (see joint plantings).

A-15 Iq STREAMBANK TREATMENT Live Stakes Live, woody cuttings which are tamped into the soil to root, grow and create a living root mat that stabilizes the soil by reinforcing and binding soil particles together, and by extracting excess soil moisture. Applications and Effectiveness • Effective where site conditions are uncomplicated, construction time is limited, and an inexpensive method is needed. • Appropriate for repair of small earth slips and slumps that are frequently wet. • Can be used to stake down surface erosion control materials. • Stabilize intervening areas between other soil bioengineering techniques. • Rapidly restores riparian vegetation and streamside habitat. • Should, where appropriate, be used with other soil bioengineering systems and vegetative plantings. • Enhance conditions for colonization of vegetation from the surrounding plant community. • Requires toe protection where toe scour is anticipated.

DATE ATTACHMENT A: Description of Proposed Work The project includes the restoration of approximately 700 linear feet of stream channel in the Yates Mill Pond watershed. The construction will include the excavation of topsoil and sod, construction of a new channel on the floodplain, and placement of fill material into the old channel to partially fill the channel and create a series of small wetlands and ponds. Erosion control matting, transplants, mulching, and seeding will be used to stabilize graded areas. Sod transplants will be used to stabilize the banks of the new constructed channel. Rock vanes, log vanes, and root wads will be placed in the new channel and at the toe of the streambanks for bank stabilization and habitat improvement. One culverted stream crossing will be installed, and 2 existing culverts will be removed.

Stream Meander Restoration Transformation of a straightened stream into a meandering one to reintroduce natural dynamics improve channel stability, habitat quality, aesthetics, and other stream corridor functions or values. Appendix A Applications and Effectiveness • Used to create a more stable stream with more habitat diversity. • Requires adequate area where adjacent land uses may constrain locations. • May not be feasible in watersheds experiencing rapid changes in land uses. • Streambank protection might be required on the outside of bends. • Significant risk of failure. • Requires a high level of anal% is. • Alay cause significant increases in flood elevations. • Effective discharge should be computed for both existing and future conditions, particularly in urbanized watersheds.

Appendix A Applications and Effectiveness • if a stable channel bed is essential to the design, grade control should bt considered as a first step before any restoration measures are imple- mented (if degradational processes exist in channel system). • Used to stop headcutting in degrading channels. • Used to build bed of incised stream to higher elevation. • Can improve bank stability in an incised channel by reducing bank heights. • Man-made scour holes downstream of structures can provide improved aquatic habitat. • Upstream pool areas created by structures provide increased low water depths for aquatic habitat. • Potential to become low flow migration barrier. • Can be designed to allow fish passage. • if significant filling occurs upstream of structure, then downstream channel degradation may result. • Upstream sediment deposition may cause increased meandering tendencies. • Siting of structures is critical component of design process, including soil mechanics and geotechnical engineering. • Design of grade control structures should be accomplished by an experi- enced river engineer.

STREAMBANK TREATMENT Bank Shaping and Planting Regrading streambanks to a stable slope, placing topsoil and other materials needed for sustaining plant growth, and selecting, installing and establishing appropriate plant species. Applications and Effectiveness • Most successful on streambanks where moderate erosion and channel migration are anticipated. • Reinforcement at the toe of the embankment is often needed. • Enhances conditions for colonization of native species. • Used in conjunction with other protective practices where flow velocities exceed the tolerance range for available plants, and where erosion occurs below base flows. • Streambank soil materials, probable groundwater fluctuation, and bank loading conditions are factors for determining appropriate slope condi- tions. • Slope stability analyses are recommended. For More Information • Consult the following references: Kos. 11, 14, 56, 61, 65, 67, 68, 77, 79. Branch Packing Alternate layers of live branches and compacted backfill which stabilize and revegetate slumps and holes in streambanks. A-10 Applications and Effectiveness • Commonly used where patches of streambank have been scoured out or have slumped leaving a void. • Appropriate after stresses causing the slump have been removed. • Less commonly used on eroded slopes where excavation is required to install the branches. • Produces a filter barrier that prevents erosion and scouring from streambank or overbank flows. • Rapidly establishes a vegetated streambank. • Enhances conditions for colonization of native species. • Provides immediate soil reinforcement. • Live branches serve as tensile inclusions for reinforcement once installed. • "Typically not effective in slump areas greater than four feet deep or four feet wide.

Some species, such as cottonwood or willow, often sprout and accelerate colonization. • Might need eventual replacement if colonization does not take place or soil bioengineering systems are not used. • Use of native materials can sequester sediment and woody debris, restore streambanks in high velocity streams, and improve fish rearing and spawning habitat. • Site must be accessible to heavy equipment. • Materials might not be readily available at some locations. • Can create local scour and erosion. • Can be expensive.

Appendix A A-15 STREAMBANK TREATMENT Live Stakes Live, woody cuttings which are tamped into the soil to root, grow and create a living root mat that stabilizes the soil by reinforcing and binding soil particles together, and by extracting excess soil moisture. Applications and Effectiveness • Effective where site conditions are uncomplicated, construction time is limited, and an inexpensive method is needed. • Appropriate for repair of small earth slips and slumps that are frequently wet. • Can be used to stake down surface erosion control materials. • Stabilize intervening areas between other soil bioengineering techniques. • Rapidly restores riparian vegetation and streamside habitat. • Should, where appropriate, be used with other soil bioengineering systems and vegetative plantings. • Enhance conditions for colonization of vegetation from the surrounding plant community. • Requires toe protection where toe scour is anticipated.
