<br />1. SEE PLAN VIEW FOR LOCATION(S) OF CULVERT INLET PROTECTION.
<br />2. CULVERT INLET PROTECTION SHOWN ON THE CRAP PLAN SHALL BE INSTALLED PRIOR TO ANY UPSTREAM
<br />LAND DISTURBING ACTIVITIES OR IMMEDIATELY FOLLOWING THE PLACEMENT OF A NEW STORM CULVERT.
<br />3. CRUSHED ROCK SMALL BE 1.S N SIZE WITH A FRACTURED FACE (ALL SIDES) AND SHALL COMPLY WITH
<br />THE RI PRM GRADATION TABLE (SEE DETAIL RS).
<br />4. ROCK SOCK SNAIL BE ONE CONTINUOUS PIECE OR SHALL BE CONSTRUCTED U31NG WIRE WRAPED JOINTS
<br />SEE DETAIL RS).
<br />5. ROCK SOCK SNAIL BE CONSTRUCTED USING 1 "CHICKEN WIRE, DOUBLE WRAPPED MADE FROM 10 GMJGE
<br />WIRE.
<br />6. CHICKEN WILE SHALL BE SECURED USING' HCIG RINGS' OR WNW TEES ON 8" CENTERS ALONG ALL JOINTS
<br />AND ON I"CENTERS ON THE ENDS OF THE SOCK.
<br />7. ROCK SOCK SHALL SE 12' IN DIAMETER.
<br />8. ROCK SOCK SHALL- EXTEND 2.0' ABOVE THE FLOW LINE ELEVATION ON BOTH SIDES OF THE CULVERT.
<br />9. A 3' DEEP TRENCH SMALL BE EXCAVATED THAT IS EQUAL TO THE LENGTH AD WIDTH OF THE
<br />CONSTRUCTED ROCK SOCK. THE ROCK SOCK SHALL BE PLACED IN THE TRENCH AND THE EXCAVATED
<br />SOIL SHALL RE COMPACTED AGAINST THE ROCK SOCK ON THE UPSTREAM SIDE.
<br />1. THE EROSION CONTROL SUPERVISOR SHALL INSPECT THE CULVERT IM.ET PROTECTION AT THE
<br />FOLLOWING INTERVALS:
<br />IMMEDIATELY FOLLOWING INITIAL INSTALLATION.
<br />EVERY 14 DAYS WHILE THE SITE IS UNDER ACTIVE CONSTRUCTION.
<br />AFTER ANY STORM EVENT THAT CAUSES SURFACE EROSION.
<br />ONCE A MONTH FOLLOWING THE END OF CONSTRUCTION, UNTIL VEGETATIVE COVER HAS REACHED A
<br />CONSISTENT DENSITY OF AT LEAST 70% OF FULL VEGETATIVE COVER.
<br />2. ACCUMULATED SEDIMENT SHALL BE REMOVED ONCE SEDIMENT HAS REACHED A DEPTH EQUAL TO IM
<br />THE HEIGHT OF CREST.
<br />3. CULVERT INLET PROTECTION IS TO REMAIN N PLACE AND PROPERLY MAINTAINED UNTIL VEGETATIVE
<br />COVER HAS REACHED A CONSISTENT DENSITY OF AT LEAST 70% OF FULL VEGETATIVE COVER AND
<br />EROSION AND SEDIMENTATION IS NO LONGER A POSSIBILITY AS DETERMINED BY THE INSPECTOR,
<br />4. WHEN THE CULVERT INLET PROTECTION IS REMOVED, ANY DISTURBED AREAS ASSOCIATED WITH THE
<br />INSTALLATION, MAINTENANCE, AND/OR REMOVAL OF THE CULVERT INLET PROTECTION SNAIL BE
<br />ROUGHENED, SEEDED, MULCHED, AND CRIMPED PER THE SEEDING SPECIFICATIONS.
