1.THE BOULDER VANE IS A DESIGN FEATURE USED TO CONTROL GRADE IN HIGH IN GRADIENT REACHES ORAT CRITICAL JUNCTURES OF THE PROPOSED CHANNEL.THIS STRUCTURE WILL ALSO ENCOURAGE POOLMAINTENANCE AND CREATE A DIVERSITY OF AQUATIC HABITAT THROUGH SCOUR OF THE RIVER BED. THEBOULDER J-HOOK IS COMPOSED OF A BOULDER SILL, WHICH IS A ROW OF BOULDERS SET AT AN ELEVATIONPROVIDED IN THE PROPOSED PROFILE THAT SPANS PERPENDICULAR TO AND SLIGHTLY ARCED ACROSSTHE CHANNEL. THE BOULDER SILL EXTENDS EXTENDS FROM A BOULDER VANE ARM INTO THE OPPOSITESTREAMBANK. THE BOULDER VANE ARM EXTENDS UP AND TOWARDS THE OUTSIDE STREAM BANK,EVENTUALLY KEYING INTO THE BANK AT AN ELEVATION HIGHER THAN THE SILL BOULDERS.2.ALL BOULDERS USED FOR THE PROPOSED STRUCTURE SHALL BE STRUCTURAL STONE, CUBICAL ORRECTANGULAR IN SHAPE. THE ENGINEER MUST APPROVE THE USE OF BOULDERS THAT MAY BE AVAILABLEONSITE.3.DIMENSIONS AND SLOPES OF STRUCTURES DESCRIBED IN THE DETAIL MAY BE ADJUSTED BY DESIGNENGINEER TO FIT CONDITIONS ONSITE.4.CONTRACTOR WILL BE REQUIRED TO FIT BOULDERS TOGETHER TIGHTLY. GAPS BETWEEN BOULDERSSHALL BE MINIMIZED BY FITTING BOULDERS TOGETHER AND PLUGGING WITH NC DOT CLASS A AND SELECTMATERIAL OR CHINKING STONE APPROVED BY DESIGN ENGINEER. BOULDERS SHALL BE 3 FT X 4 FT X 2 FT+/- 0.5 FT.5.NON-WOVEN GEOTEXTILE SHALL BE PLACED ON THE UPSTREAM SIDE OF THE STRUCTURE TO PREVENTWASHOUT OF SEDIMENT THROUGH BOULDER GAPS. FILTER FABRIC SHALL EXTEND FROM THE BOTTOM OFTHE FOOTER BOULDER TO THE FINISHED GRADE ELEVATION AND SHALL BE PLACED THE ENTIRE LENGTHOF THE STRUCTURE.
