The slope of the top surface of the vane will be 5 -7 percent The vane should extend from the bank to approximately 1/3 of channel width (See fig 1) J -HOOK - A rock vane with a hooked portion on the streambed The hook provides additional habitat. (See fig 2) May included a sill (See fig 3) which continues across the stream bed from the hook portion of the structure, perpendicular to the flow and follows the shape and elevation of the stream bed and stream bank up to interberm or °as directed by the engineer CROSS VANE - A rock vane from both sides of the stream with a connecting bar on the streambed. If this structure is used for grade control,, the existing streambed elevation may be increased by no more than 10 percent of bankfull, unless a greater increase is provided form the approved design (See fig 4) WING DEFLECTOR - A deflective structure installed with sloping "arms" the slope downward into the stream bed. The angle the arms point downstream and upstream from the bank is 20 — 30 degrees The slope of the top surface of the "arms" will be 2 — 4 percent The vane should extend from the bank and help identify the low flow channel (See figure on the attached drawing) ENGINEER = The USDA -NRCS and/or SWCD person(s) who have appropriate, construction approval authority for Practice Standard 580, Streambank and Shoreline Protection for the specific size and type of structure USDA -NRCS page 1 of 6 Rock Structures North Carolina August 1999 STREAMBANK — portions of intermittent or perennial streambanks which are eroding at an accelerated' rate due to the effects of stream flow near banks without adequate vegetative cover and supporting riparian area BANKFULL — The stream flow level at which the stream channel is formed and maintained The term " bankfull" should not be confused with "the top of the bank" Persons who have received training in Natural Stream Channel evaluation shall identify the bankfull elevation THALWEG - The deepest part of the channel where the highest channel velocities occur 4) PLANNING CONSIDERATIONS This practice should be applied as a part of a total Natural Stream Channel Restoration design These structures are not intended to be a total solution to the.streambank erosion problem in themselves They are to be used as a component of a total streambank management plan, which may require a number of associated practices. In some cases modification of the stream dimension, pattern and profile may be required before,structures are installed. The use of rock structures without considering the stable dimension, pattern, and profile, of the stream will most likely result in failure. 5) PERMITTING No work, which is covered by this specification, shall be performed until the Army Corp of Engineers has' issued a Section 404 permit and the Division of Water Quality has issued a Section 401 certification (if required) The final construction plans and specifications must be prepared and approved prior to the beginning of construction 6) EQUIPMENT A hydraulic excavator,(trackhoe) with a hydraulic "thumb" shall be used to handle and install the rocks All required safety equipment shall be available during construction Safety equipment includes but is not limited to hard hats, gloves, and eye and hearing protection 7) SUPERVISION The engineer must be on -site to supervise and inspect each operation as it is performed. No work, which is covered by this specification, shall be performed in the absence of the engineer except as approved by the engineer The work shall be conducted as directed by the engineer. The engineer,shall be notified a minimum of 24 hours before installation is performed. 8) INSTALLATION USDA -NRCS page 2 of 6 Rock Structures North Carolina August 1999 • Theengineenshall place a marker at the point'where the last rock of the structure will meet the streambed. This marker shall be set at a point, which represents the planned angle from bankfull and the planned slope of the structure. The engineer should check to see if this point is approximately 1/3 of the total channel width • Holes for footer rocks shall be excavated in the streambed at the location, elevation and orientation.as directed by theaengineer. • A footer rock of the size and shape as directed by the engineer shall be installed in the hole. Multiple footer rocks may be required, at the discretion of the engineer or as provided for in the approved plan • A structure rock of the size and shape as directed by the engineer shall be installed on top of the footer rock • Streambed material will be removed as directed by the engineer if it is required to move the, thalweg of the stream to the point of the structure • Streambed material shall be placed on the upstream side of the structure near the bank. • Equipment shall be operated from the streambank whenever possible • Equipment which appears to be leaking fluids shall be removed to a safe site away from the stream corridor until it is repaired and confirmed that no leaks exist. 9) ASSOCIATED PRACTICES • ROOT WADS and related instream, structures planned as an integral component of the natural stream channel restoration design. • CRITICAL AREA SEEDING shall be applied on all disturbed areas. • WOODY VEGETATION shall be established on the sloped bank above bankfull and on top of the bank • RIPARIAN FOREST BUFFER should be considered • LIVESTOCK EXCLUSION shall be installed if livestock are pastured in the area. 10) FIGURES Figures attached to this specification illustrate the placement and orientation of the various instream rock structures which may be included in the plan.

Ingress and egress of equipment and materials shall be only at locations and through routes as approved by the Engineer. c Provide all equipment, tools, materials and labor required to install two Wing Deflectors which will require approximately 40 boulders one each structure and approximately 20 boulders for the second structure (60 total), each boulder approximately 2'x 3'x 4' or of a similar mass. d Provide all equipment, tools, materials and labor required to install Toe Rocks along bank sections as shown on the drawings and/or as directed by the engineer. The Toe Rocks will require approximately 60 boulders Each boulder shall be approximately 2'x 3'x 4' or of a similar mass e Provide approximately 20 additional boulders for miscellaneous work (repair of existing J- Hook, additional Toe Rock, etc.) ' f A total of approximately 140 boulders will be required — approximately 187 tons g.
