MAINTENANCE ACTIVITIES INCLUDE THE CONSTRUCTION OF DRAINAGE IMPROVEMENTS AND SITE GRADING. THE DISTURBANCE AREA ASSOCIATED WITH THIS PROJECT IS ±1.60 AC (69,786 SF). IT IS ANTICIPATED THAT THE WORK WILL START IN NOVEMBER 2018 AND LAST 4 TO 6 MONTHS. EXISTING SITE CONDITIONS: THE SITE CONSISTS MAINLY OF AN EXISTING FLAT FIELD THAT HAS BEEN COMPACTED OVER USE AND NO LONGER DRAINS EFFECTIVELY. RECREATIONAL VEHICLE PARKING SPOTS AND UTILITY CONNECTIONS SURROUND THE FIELD ON THE WEST AND SOUTH SIIDE OF THE FIELD, AND ARE ACCESSED BYAN EXISTING GRAVEL ROAD. TO THE NORTH AND EAST ARE CAMPGROUND AMENITIES AND ASSOCIATED BUILDINGS, ALONG WITH A PAVED ENTRANCE ROAD TO THE EAST. THE SLOPES WITHIN THE PROJECT AREA RANGE FROM 0% TO 2%! ADJACENT AREAS: THE PROPOSED PROJECT IS BORDERED BY EXISTING ACTIVE FARMLAND TO THE WEST AND ADDITIONAL CAMPSITE AND RV AREAS TO THE EAST. TO THE NORTH IS A FAIRLY STEEP SLOPE ABOVE WHICH RUNS ROUTE 250. DIRECTLY TO THE SOUTH OF THE GRAWEL ACCESS ROAD IS THE 100 -YEAR FLOODPLAIN ASSOCIATED WITH STOCKTON CREEK, WHICH RUNS WEST TO EAST. SOME OFTHE EXISTING RV PARKING SITES ARE WITHIN THE LIMITS OFTHE FLOODPLAIN, HOWEVER THESE WILL NOT BE MODIFIED. THE WATER PROTECTION ORDINANCE BUFFER IS CONCURRENT WITH THE LIMITS OFTHE 100 -YEAR FLOODPLAIN. OFF-SITE AREAS: IT IS NOT ANTICIPATED THAT ANY OFF-SITE AREAS WILL BE DISTURBED DURING CONSTRUCTION. THIS WOIRK WILL REQUIRE A NET FILL CONDITION, AND STOCKPILE AREAS ARE LABELED ON THE PLANS. UNSUITABLE MATERIALS RESULTING FROM THE PROPO-SED WORK SHALL BE HAULED FROM THE SITE AND DISPOSED OF AT AN APPROVED DISPOSAL SITE PERMITTED SEPARATELY FROM THIS PROJECT. SOILS: SEE THE USDA SOILS DELINEATION MAP ON THIS SHEET. CRITICAL AREAS: CRITICAL AREAS CONSIST OF THE FLOODPLAIN TO THE SOUTH AND THE HEDGE OF MATURE TREES ALONG THE WESTERN PROPERTY LINE. THE CONTRACTOR SHALL TAKE EXTRA CARE TO PREVENT SEDIMENTATION OR EROSION OFTHE FLOODPLAIN AND THE CRITICAL ROOT ZONES OF TH E TREES. EROSION & SEDIMENT CONTROL MEASURES: REFER TO THIS SHEET FOR A LIST OF ALL PROPOSED EROSION AND SEDIMENT CONTROL MEASURES TO BE USED ON SITE. PERMANENT STABILIZATION: THE SITE WILL BE STABILIZED THROUGH THE USE OF PERMANENT SEEDING, STONE AND RIPRAP, AND LANDSCAPING. SEEDING INFORMATION, DATES AND AMENDMENTS ARE INCLUDED ON THE PLANS. SOILTESTING SHALL BE COMPLETED THE CONTRACTOR TO DETERMINE THE SUITABILITY OF EXISTING SOILS AND THE NEED FOR ANY SOIL AMENDMENTS TO ENSURE THAT PERMANENT SEEDING WILL GROW EFFECTIVELY. STORM WATER RUNOFF CONSIDERATIONS: THE MAJORITY OF STORMWATER RUNOFF DURING CONSTRUCTION WILL BE DIRECTED TO A SEDIMENT TRAP LOCATED AT THE SOUTHEAST CORNER OF THE SITE. CLEAN WATER FROM UP -GRADIENT OF THE SITE SHALL BE DIRECTED AROUND THE SITE TO AN EXISTING CULVERT VIA A DIVERSION DIKE.
