BEFORE ANY CLEARING OR GRUBBING OF THE SITE IS INITIATED, AND DURING EARTHWORK PHASES, SEDIMENT TRAPS SHALL BE CONSTRUCTED IN ALL STORM SWALES AND DITCHES AND AS INDICATED ON THE PLAN. 2. SEDIMENT TRAPS SHALL CONSIST OF PREFABRICATED DAMS OR CRUSHED STONE PLACED TO FORM A PERVIOUS BARRIER IN THE SWALE OR DITCH. 3. AFTER EVERY STORM EACH SEDIMENT TRAP SHALL BE INSPECTED FOR FAILURES OR CLOGGING, AND ANY FAILURE OR CLOGGING SHALL BE IMMEDIATELY CORRECTED. 4. ALL BARE EARTH AREAS SHALL BE SEEDED AND MULCHED AS SOON AS IS POSSIBLE TO PREVENT EROSION, AND EVERY BARE EARTH AREA SHALL BE SEEDED AND MULCHED BY OCTOBER 1st. TEMPORARY RAPID GROWTH COVER CROPSS, SUCH AS ANNUAL RYEGRASS MAY BE USED FOR TEMPORARY SURFACE STABILIZATION. 5. SMALL BENCHES AND TEMPORARY INTERCEPTOR DITCHES, INCORPORATING SEDIMENT TRAPS, SHALL BE CONSTRUCTED WHERE LONG SLOPES ARE STRIPPED OF COVER GRASSES, OR WHERE FILL AREAS ARE EXTENSIVE. 6. NEW SWALES AND UNLINED DITCHES SHALL INCORPORATE MATTING OR NETTING OVER SEED AND MULCH WHEN THE INVERT SLOPE EXCEEDS 2% ALL SWALES AND UNLINED DITCHES SHALL BE SEEDED WITH REED -CANARY GRASS FOR FOUR(4) FEET EITHER SIDE OF THE SWALE OR DITCH CENTERLINE, AT A RATE OF 25 POUNDS per ACRE AFTER JUNE, ALL SEEDED AREAS SHALL BE MULCHED WITH STRAW IMMEDIATELY. 7. THE CONTRACTOR SHALL COMPLY WITH THE NEW YORK GUIDELINES FOR URBAN EROSION AND SEDIMENT CONTROL AS PUBLISHED BY THE EMPIRE STATE CHAPTER OF THE SOIL AND WATER CONSERVATION SOCIETY. MAINTENANCE 1. SEDIMENT SHALL BE REMOVED FROM SEDIMENT TRAPS WHENEVER THEIR CAPACITY HAS BEEN REDUCED BY 507*. 2. ALL EROSION AND SEDIMENT CONTROL DEVICES SHALL BE INSPECTED WITHIN 24 HOURS OF A STORM EVENT AND REPAIRED AND/OR MODIFIED AS REQUIRED TO BE GOOD WORKABLE CONDITION. 3. THE CONTRACTOR SHALL CONDUCT AN INSPECTION OF THE SITE ON A DAILY BASIS TO COLLECT LITTER AND CONSTRUCTION DEBRIS AND DISPOSE OF LEGALLY. 4. ANY STOCKPILES OF FILL., TOPSOIL, EXCAVATED MATERIAL SHALL BE COVERED OR CONTAINED BY SEDIMENT CONTROL FENCE TO PREVENT EROSION. CONSTRUCTION SEQUENCING 1. PRIOR TO START OF CONSTRUCTION, THE CONTRACTOR SHALL INSTALL THE SEDIMENT CONTROL FENCING AROUND THE PERIMETER OF THE CONSTRUCTION SITE AT THE EDGE OF EXISTING NATIVE VEGETATION AND AS INDICATED ON THE PLANS AND DETAILS. 2. TEMPORARY SILT BASINS ARE TO BE CONSTRUCTED AS SHOWN ON THE PLANS. THEY SHALL COLLECT STORMWATER RUNOFF FROM ALL AREAS OF PROPOSED ROAD AND UTILITY CONSTRUCTION. BASINS SHALL HAVE A MINIMUM VOLUME OF 3,600 CUBIC FEET FOR EACH ACRE OF TRIBUTARY AREA. BASINS SHALL ALLOW COLLECTED WATER TO FILTER INTO THE EXISTING SANDY SOIL IF NECESSARY CLEAN SEDIMENT OUT OF BASINS TO MAINTAIN THEIR INFILTRATIVE CAPABILITY. 3. CONSTRUCTION OF THE BUILDING AND SITE INFRASTRUCTURE CAN THEN PROCEED. 4. FOLLOWING COMPLETION OF THE STORM DRYWELLS, THE CONTRACTOR SHALL INSTALL SILT DAMS TO PREVENT STORMWATER AND SILT FROM ENTERING THE DRYWELLS UNTIL THE SITEWORK IS COMPLETE AND GRASS IS ESTABLISHED. 5. FOLLOWING COMPLETION OF ALL PLANTING AND THE ESTABLISHMENT OF ALL GRASS AREAS, REMOVE ANY COLLECTED SEDIMENT, REMOVE THE SEDIMENT CONTROL FENCING, REMOVE ANY DEBRIS FROM THE PERIMETER OF THE SITE AND DISPOSE OF ALL WASTE MATERIAL IN A LEGAL MANNER. STABILIZATION 1. THE CONTRACTOR SHALL INITIATE STABILIZATION MEASURES AS SOON AS PRACTICABLE IN PORTIONS OF THE SITE WHERE ACTIVITIES HAVE TEMPORARILY OR PERMANENTLY CEASED, BUT IN NO CASE MORE THAN 14 DAYS. 2. STABILIZATION OF GRASS AREAS INCLUDES HYROSEEDING USING TACKIFIER ON SLOPES OVER 5:1 OR SEEDING AND INSTALLING A CONTINUOUS COVER OF STRAW MULCH WATERED INTO PLACE. ON SLOPES OVER 4:1 INSTALL EROSION CONTROL BLANKET - NORTH AMERICAN GREEN S-75 OR EQUAL IN ACCORDANCE WITH MANUFACTURERS INSTRUCTIONS. ••s EXISTING OUTDOOR TRACK PROPOSED TEMPORARY SEDIMENT BASIN; 2' DEPTH REQUIRED STORAGE = 3800 CF STORAGE PROVIDED = 4200 CF SEDIMENT & EROSION CONTROL REQUIREMENTS Mnr S W P P P REQUIREMENTS 1.
