ALL DATES SHOWN ARE NOMINAL AND MAY BE VARIED WITH CONCURRENCE OF THE LANDSCAPE ARCHITECT OR THE LOCAL SOIL CONSERVATIONIST. SOIL EROSION CONTROL SEQUENCE: THE FOLLOWING IS A UST IN SEQUENCE OF CONSTRUCTION ACTIVITIES TO CONTROL SOIL EROSION: 1. CONTRACTOR SHALL INSTALL SEDIMENT TRAPS AND STRAW BALE FILTERS AS PART OF INITIAL PHASE OF ANY WORK TO ENSURE MAXIMUM SILT RETENTION ON -SITE. 2. MASS GRADE THE SITE; SIDES OF SWALES, MOUNDS AND PONDS TO BE SEEDED AND MULCHED IMMEDIATELY UPON COMPLETION. TEMPORARY SEEDING SHALL BE REQUIRED FOR ALL SWALES AND DISTURBED AREAS THAT CANNOT BE FINAL SEEDED WITHIN A TIME PERIOD THAT WILL PREVENT SLOPE EROSION. FOR TEMPORARY SEEDING, THE CONTRACTOR SHALL UTILIZE A FAST GROWING SEED OF EITHER OATS, ANNUAL RYEGRASS, WHEAT OR RYE DEPENDING ON TIME OF YEAR. DISTURBED AREAS SHALL BE KEPT TO A MINIMUM AT ALL TIMES. 3. CONTRACTOR SHALL CONTROL DEBRIS ACCUMULATION ON ALL STREETS SURROUNDING PROJECT BY INSTAWNG STONE SURFACE AT ALL LOCATIONS WHERE CONSTRUCTION TRAFFIC LEAVES THE SITE. DUST SHALL BE KEPT TO A MINIMUM BY UTILIZING SPRINKLING, CALCIUM CHLORIDE, VEGETA11VE COVER, SPRAY-ON ADHESIVES OR OTHER APPROVED METHODS. 4. MAINTAIN ALL FILTERS AND TRAPS DURING CONSTRUCTION TO PREVENT ANY BLOCKAGES FROM ACCUMULATED SEDIMENT. ADDITIONAL SEEDING AND STRAW BALES MAY BE REQUIRED 5. CONTRACTOR SHALL INSTALL ALL SANITARY SEWERS, STORM SEWERS, SUBSURFACE DRAINS AND WATER MAINS. DRAINAGE BARRIORS PER THIS SHEET SHALL BE INSTALLED AT ALL 6. ALL PROPOSED STREET AREAS SHALL BE PAVED AS SOON AS POSSIBLE AFTER SUBGRADE IS PREPARED. 7. ALL DISTURBED AREAS SHALL BE SEEDED AND MULCHED AS SPECIFIED. 8. CONTRACTOR SHALL MAINTAIN ALL TEMPORARY EROSION CONTROL MEASURES THROUGHOUT THE CONSTRUCTION PHASE OF THIS PROJECT. REMOVE ALL TEMPORARY EROSION AND SEDIMENT CONTROLS ONLY WHEN THERE IS A SUFFICIENT GROWTH OF GROUND COVER TO PREVENT FURTHER EROSION. EROSION CONTROL BLANKET: 1. THE BLANKET SHALL BE OF CONSISTENT THICKNESS WITH THE STRAW EVENLY DISTRIBUTED OVER THE EN11RE AREA OF THE MAT. THE BLANKET SHALL BE COVERED ON THE TOP SIDE WITH POLYPROPYLENE NETTING HAVING AN APPROXIMATE 5/8" X 5/8" MESH, AND ON THE BOTTOM WITH A POLYPROPYLENE NETTING WITH AN APPROXIMATE 1/4" X 1/4" MESH. THE BLANKET SHALL BE SEWN TOGETHER WITH COTTON THREAD. 2. STRAW EROSION CONTROL BLANKET (OR LOW VELOCITY CHANNEL LINING) SHALL BE SC150 (ALL STRAW) AS MANUFACTURED BY NORTH AMERICAN GREEN, OR EQUIVALENT. EROSION CONTROL BLANKET OR CHANNEL LINING SHALL HAVE THE FOLLOWING PROPERTIES: A. MATERIAL CONTENT: STRAW 70% (.35 LB /SQ. YD.) COCONUT FIBER 30% (.15 LB /SQ. YD.) NET11NG ONE SIDE LIGHTWEIGHT PHOTO DEGRADABLE (1 LB /1000 SQ. FT. APPROX. WT.) ONE SIDE HEAVYWEIGHT PHOTO DEGRADABLE (3 LB /1000 SQ. FT. APPROX. WT.) THREAD COTTON B.

SMOOTH GRADE AND COMPACT ALL AREAS TO BE COVERED WITH MAT. 2. REMOVE ALL ROCKS, DIRT CLODS, GRASS CLUMPS. TRASH AND OTHER DEBRIS THAT WILL LIFT MAT FROM GROUND SURFACE. ANCHOR TRENCHES: 1. THE MAT MUST BE ANCHORED AT THE UPSTREAM AND DOWNSTREAM ENDS OF THE PROTECTED AREA AND INTERMITTENTLY IN BETWEEN. 2. EXCAVATE END TRENCHES TO A MINIMUM OF 12" DEEP AND 6" WIDE BEFORE PLACING MAT. 3. DIG INTERMITTENT CHECK SLOTS 6 DEEP BY 6' WIDE TRANSVERSE TO MAT AT APPROXIMATELY 25' INTERVALS. SEED ING: 1. SEED AND FERTILIZER SHALL BE SPREAD BEFORE MAT INSTALLATION. SEED TYPE, FERTILIZER TYPE AND RATE OF APPLICATION SHALL COMPLY WITH SEEDING SPECIFICATIONS. MAT PLACEMENT: 1. UNROLL MAT FLAT SIDE AGAINST THE GROUND. UNROLL MAT IN DIRECTION PARALLEL WITH DIRECTION OF WATER FLOW. 2. MAT SHOULD LAY FLAT. DO NOT PULL MAT TAUT OVER GROUND. PUWNG TAUT MAY CAUSE MAT TO BRIDGE DEPRESSIONS IN THE SURFACE AND ALLOW EROSION UNDERNEATH TO OCCUR. 3.
