THE PRIMARY GOALS OF THE SEDIMENT AND EROSION CONTROL PLAN ARE TO PREVENT THE TRACKING OF DIRT AND MUD ONTO ADJACENT ROADS, TO PREVENT MUD AND SILT FROM ENTERING INTO EXISTING AND PROPOSED DRAINAGE FACILITIES, AND TO PROTECT THE RECEIVING WATERS FROM CONTAMINATION DURING THE CONSTRUCTION. DURING CONSTRUCTION, THE PARTY RESPONSIBLE FOR IMPLEMENTING THE TEMPORARY (DURING CONSTRUCTION) STORMWATER MANAGEMENT FACILITIES MAINTENANCE PROGRAM WILL BE THE OWNER. - THE NAME AND CONTACT A NEW YORK STATE PROFESSIONAL ENGINEER OR CERTIFIED PROFESSIONAL IN EROSION AND SEDIMENT CONTROL (P.E. OR CPESC) SHALL CONDUCT AN ASSESSMENT OF THE SITE PRIOR TO THE COMMENCEMENT OF CONSTRUCTION AND CERTIFY IN AN INSPECTION REPORT THAT THE APPROPRIATE EROSION AND SEDIMENT CONTROLS SHOWN ON THE PLAN HAVE BEEN ADEQUATELY INSTALLED AND/OR IMPLEMENTED TO ENSURE OVERALL PREPAREDNESS OF THE SITE FOR CONSTRUCTION. FOLLOWING THE COMMENCEMENT OF CONSTRUCTION, SITE INSPECTIONS SHALL BE CONDUCTED BY THE P.E. OR CPESC AT LEAST EVERY 7 CALENDAR DAYS AND WITHIN 24 HOURS OF THE END OF A STORM EVENT OF 0.5 INCHES OR GREATER. DURING EACH INSPECTION, THE REPRESENTATIVE SHALL RECORD THE FOLLOWING: 1. ON A SITE MAP, INDICATE THE EXTENT OF ALL DISTURBED SITE AREAS AND DRAINAGE PATHWAYS. INDICATE SITE AREAS THAT ARE EXPECTED TO UNDERGO INITIAL DISTURBANCE OR SIGNIFICANT SITE WORK WITHIN THE NEXT 14-DAY PERIOD; 2.INDICATE ON A SITE MAP ALL AREAS OF THE SITE THAT HAVE UNDERGONE TEMPORARY OR PERMANENT STABILIZATION; 3.INDICATE ALL DISTURBED SITE AREAS THAT HAVE NOT UNDERGONE ACTIVE SITE WORK DURING THE PREVIOUS 14-DAY PERIOD; 4.INSPECT ALL SEDIMENT CONTROL PRACTICES AND RECORD APPROXIMATE DEGREE OF SEDIMENT ACCUMULATION AS A PERCENTAGE OF THE SEDIMENT STORAGE VOLUME; 5.INSPECT ALL EROSION AND SEDIMENT CONTROL PRACTICES AND RECORD ALL MAINTENANCE REQUIREMENTS. IDENTIFY ANY EVIDENCE OF RILL OR GULLY EROSION OCCURRING ON SLOPES AND ANY LOSS OF STABILIZING VEGETATION OR SEEDING/MULCHING. DOCUMENT ANY EXCESSIVE DEPOSITION OF SEDIMENT OR PONDING WATER ALONG THE BARRIER. RECORD THE DEPTH OF SEDIMENT WITHIN CONTAINMENT STRUCTURES AND ANY EROSION NEAR OUTLET AND OVERFLOW STRUCTURES. 6. ALL IDENTIFIED DEFICIENCIES. THE P.E. OR CPESC SHALL MAINTAIN A RECORD OF ALL INSPECTION REPORTS IN A SITE LOGBOOK. THE SITE LOGBOOK SHALL BE MAINTAINED ON -SITE AND BE MADE AVAILABLE TO THE TOWN/VILLAGE OF HARRISON AND THE NYSDEC A SUMMARY OF THE SITE INSPECTION ACTIVITIES SHALL BE POSTED ON A MONTHLY BASIS IN A PUBLICLY ACCESSIBLE LOCATION AT THE SITE. THE PROJECTS ANTICIPATED START DATE IS APRIL 2024 AND THE ANTICIPATED COMPLETION DATE IS ESTIMATED TO OCCUR BY APRIL 2026. CONSTRUCTION SEQUENCING THE FOLLOWING EROSION CONTROL SCHEDULE SHALL BE UTILIZED: ROADWAY: 1. PLACE ORANGE CONSTRUCTION FENCING AROUND ALL AREAS TO BE USED FOR EX -FILTRATION TO AVOID UNNECESSARY COMPACTION. 2.INSTALL ORANGE CONSTRUCTION FENCE IN ALL LOCATIONS SHOWN ON THE PLANS. 3.PROTECT TREES AND PLANTS INDICATED TO REMAIN WITHIN AND IMMEDIATELY ADJACENT TO THE GRADING LIMIT LINE WITH TEMPORARY ORANGE CONSTRUCTION FENCING OR SOLIDLY CONSTRUCTED WOOD BARRICADES AS REQUIRED. PROTECT ROOT SYSTEMS FROM SMOTHERING. DO NOT STORE EXCAVATED MATERIAL, OR ALLOW VEHICULAR TRAFFIC OR PARKING WITHIN THE CANOPY DRIP LINE. RESTRICT FOOT TRAFFIC TO PREVENT EXCESSIVE COMPACTION OF SOIL OVER ROOT SYSTEMS. STORE MATERIALS AND EQUIPMENT IN CLEARED AREAS AWAY FROM TREE ROOTS. PREVENT EMPLOYEES AND EQUIPMENT FROM TRAMPLING OVER WOODLAND, EXISTING PLANTING, AND ESTABLISHED LAWNS 4. SELECTIVE VEGETATION REMOVAL FOR SILT FENCE INSTALLATION. 5.INSTALL SILT FENCE DOWN SLOPE OF ALL AREAS TO BE DISTURBED AS SHOWN ON THE PLAN. &INSTALL A CONSTRUCTION ENTRANCE TO THE DEVELOPMENT AREA. 7. ESTABLISH CONSTRUCTION STAGING AREA ADJACENT TO THE END OF THE ROADWAY ENTRANCE. & REMOVE TREES WHERE NECESSARY (CLEAR & GRUB) FOR THE CONSTRUCTION OF THE PROPOSED ROADWAY, CUL-DE-SAC, AND STORMWATER/UTILITY EXTENSIONS TO THE PROPOSED DEVELOPMENT (INSTALL ADDITIONAL SILT FENCE DOWN SLOPE OF DISTURBED AREAS AS NECESSARY). PREVENT DAMAGE TO BUILDINGS, PAVEMENT, PIPES, CONDUITS, POLES AND OTHER STRUCTURES ABOVE AND BELOW GROUND THAT ARE ADJOINING OR INCLUDED IN THE CONTRACT AREA. REPAIR DAMAGE RESULTING FROM THE CONTRACTOR'S NEGLIGENCE. REMOVE TREES WHERE INDICATED, AS FOLLOWS (REMOVAL OF EXISTING TREES SHALL BE LIMITED TO THE AREA OF EACH INDIVIDUAL PHASE OF CONSTRUCTION. NO TREES SHALL BE DISTURBED OUTSIDE OF THESE AREAS): a. TOP AND LIMB ALL TREES BEFORE FALLING, UNLESS OTHERWISE APPROVED BY THE ENGINEER. b. CHIP OUT STUMPS TO A DEPTH OF NOT LESS THAN 6 INCHES BELOW FINISHED GRADE. BACKFILL STUMP HOLES WITH TOPSOIL, AND SEED c. REMOVE AND DISPOSE OF ALL LOGS, TREE TRIMMINGS, AND DEBRIS FROM PROPERTY. LEAVE WORK AREA IN A NEAT UNCLUTTERED CONDITION. d. RESTORE GRADES TO INDICATED LEVELS WHERE SETTLEMENT OR DAMAGE DUE TO PERFORMANCE OF THE WORK HAS OCCURRED. CORRECT CONDITIONS CONTRIBUTING TO SETTLEMENT OR DAMAGE. e.
