TO REDUCE EROSION AND DECREASE SEDIMENT YIELD FROM DISTURBED AREAS. TO PERMANENTLY STABILIZE DISTURBED AREAS IN A MANNER 77 -IAT IS ECONOMICAL, ADAPTABLE TTO SITE CONDITIONS, AND ALLOWS SELECTION OF THE MOST APPROPRIATE PLANT MATERIALS. TO IMPROVE WILDLIFE HABITAT. TO ENHANCE NATURAL BEAUTY. UPON COMPLE77ON OF CONSTRUC77ON AC77VI77ES, ALL AREAS WILL RECEIVE A PERMANENT VEGETATIVE COVER. 3.35 MULCHING: APPLICATION OF PLANT RESIDUES OR OTHER SUITABLE MATERIALS TO THE SOIL SURFACE. TO PREVENT EROSION BY (PROTECTING THE SOIL SURFACE FROM RAINDROP IMPACT AND REDUCING THE VELOCITY OF OVERLAND FLOW. TO FOS7ER 7HE GROWTH OF VEGETA77ON BY INCREASING .AVAILABLE MOISTURE AND PROVIDING INSULA77ON AGAINST EXTREME HEAT AND COLD. AREAS WHICH HAVE BEEN PERMANENTLY SEEDED SHOULD BE MULCHED IMMEDIA 7TELY FOLLOWING SEEDING. AREAS WHICH CANNOT BE SEEDED BECAUSE OF THE SEASON SHOULD BE MULCHED USING ORGANIC MULCH. MULCH MAY BE USED TOGE7HER? WITH PLAN77NGS OF TREES, SHRUBS, OR CERTAIN GROUND COVERS WHICH DO NOT PROVIDE ADEQUATE SOIL STABILIZATION BY THEMSELVES, CAN BE USED /N (CONJUNC77ON WITH TEMPORARY SEEDING. 3.36 SOIL STABILIZA 77ON BLANKETS & MATTING.' THE INSTALLAT70N OF A PR07ECTIVE COVERING (BLANKET) OR A SOIL STABILIZATION MAT ON A PREPARED PLANTING AREA OF A STEEP SLOPE, CHANNEL OR SHORELINE. TO AID IN CONTROLLING EROSION ON CRITICAL AREAS BY PROVIDING A MICROCLIMATE WHICH PROTECTS )YOUNG VECETA77ON AND PROMOTES ITS ESTABLISHMENT.

DUST CONTROL MEASURES SHALL BE EMPLOYED TO PREVENT SURFACE AND AIR WOVEMENT OF DUST DURING CONSTRUCTION. MEASURES EMPLOYED SHALL BE IN ACCORDANCE WITH THE VESCH. SHEET LAYOUT SCALE: 1" = 100' TTffPORAR}Y STTDI1W ..- ALL DENUDED AREAS WHICH WILL BE LEFT DORMANT FOR EXTENDED PERIODS OF TIME SHALL BE SEEDED WITH FAST GERMINATING TEMPORARY VEGETATION IMMEDIATELY FOLLOWING GRADING. SELECTION OF THE SEED MIXTURE WILL DEPEND ON THE TIME OF YEAR AND WILL BE APPLIED TO DISTURBED ARES THAT WILL NOT HE BROUGHT TO FINAL GRADE WITHIN 30 DAYS. PLANTS SHOULD BE SELECTED APPROPRIATE TO THE SEASON' AND SITE CONDITIONS FROM TABLES 3.31B AND 3.31 C. NOTE THAT TABLE 3.31B PRESENTS PLANTS WHICH CAN BE USED WITHOUT EXTENSIVE EVALUATION OF SITE CONDITIONS; TABLE 3.31C PRESENTS MORE IN-DEPTH INFORMATION ON THE PLANT MATERIALS TO CONTROL EROSION ON BARE SOIL SURFACES, PLANTS MUST BE ABLE TO GERMINATE AND GROW. SEEDBED PREPARA77ON IS ESSENTIAL. AN EVALUATION SHOULD BE CONDUCTED TO DETERMINE IF LIME IS NECESSARY FOR TEMPORARY SEEDING. TABLE 3.31A MAY BE USED TO DETERMINE THE ACTUAL NEED ALONG WITH SUGGESTED APPLICATION RATES: FERTILIZER SHALL BE APPLIED AS 600 LBS/ACRE OF 10-20-10 (14 LBS/1,000 SQ. FT.) OR EQUIVALENT NUTRIENTS LIME AND FERTILIZER SHALL BE INCORPORATED INTO THE TOP 2 TO 4 /INCHES OF THE SOIL IF POSSIBLE. IF THE AREA HAS BEEN RECENTLY LOOSENED OR DISTURBED, NO FURTHER ROUGHENING IS REQUIRED. WHEN THE AREA IS COMPACTED, CRUSTED, OR HARDENED, THE SOIL SHALL BE LOOSENED BY DISCING, RAKING, HARROWING, OR OTHER ACCEPTABLE MEANS. TRACKING WITH BULLDOZER CLEATS IS MOST EFFECTIVE ON SANDY SOILS. THIS PRACTICE OFTEN CAUSES UNDUE COMPACTION OF THE SOIL SURFACE, ESPECIALLY IN CLAYEY SOILS, AND DOES NOT AID PLANT GROWTH AS EFFECTI VEL Y AS OTHER METHODS OF SURFACE ROUGHENING. SEED SHALL BE EVENLY APPLIED WITH A BROADCAST SEEDED, DRILL, CULTIPACKER SEEDER OR HYDROSEEDER. SMALL GRAINS SHALL BE PLANTED NO MORE THAN 1j INCHES DEEP. SMALL SEEDS, SUCH AS KENTUCKY BLUEGRASS, SHOULD BE PLANTED NO MORE THAN 4 INCH DEEP. OTHER GRASSES AND LEGUMES SHOULD BE PLANTED FROM j INCH TO � DEEP. SEEDINGS MADE IN FALL FOR WINTER COVER AND DURING HOT AND DRY SUMMER MONTHS SHALL BE MULCHED ACCORDING TO MULCHING, STD. & SPEC. 3.35, EXCEPT THAT HYDROMULCHES (FIBER MULCH) WILL NOT BE CONSIDERED ADEQUATE. STRAW MULCH SHOULD BE USED DURING THESE PERIODS. AREAS WHICH FAIL TO ESTABLISH VEGETATIVE COVER ADEQUATE TO PREVENT RILL EROSION WILL BE RE -SEEDED AS SOON AS SUCH AREAS ARE IDENTIFIED. MAINTENANCE'.• IN GENERAL, DURING CONSTRUCTION THE RLD OR CONTRACTOR ON-SITE WILL CHECK ALL EROSION AND SEDIMENT CONTROL MEASURES DAILY AND AFTER EACH SIGNIFICANT RAINFALL. MONITORING REPORTS WILL BE REQUIRED FROM THE RLD IF NEEDED. SPECIFIC ATTENTION WILL BE GIVEN TO THE FOLLOWING ITEMS: a. SEDIMENT BASINS & TRAPS WILL BE CLEANED AND MAINTAINED IN ACCORDANCE WITH THE VIRGINIA EROSION & SEDIMENT CONTROL HANDBOOK. b. ALL INLET PROTECTION AND GRAVEL OUTLETS WILL BE CHECKED REGULARLY FOR SEDIMENT BUILDUP THAT WILL PREVENT PROPER DRAINAGE. IF THE GRAVEL IS CLOGGED BY SEDIMENT, THE GRAVEL WILL BE REMOVED AND CLEANED, OR IT WILL BE REPLACED. c. ALL SIL T FENCE BARRIERS WILL BE CHECKED REGULARL Y FOR UNDERMINING OR DETERIORA TION OF THE FABRIC AND REPAIRED AS REQUIRED. SEDIMENT SHALL BE REMOVED WHEN THE LEVEL OF SEDIMENT DEPOSITION REACHED HALF WAY TO THE TOP OF THE BARRIER. d. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO SEiE THAT A GOOD STAND IS MAINTAINED. AREAS SHOULD BE FERTILIZED AND RESEEDED AS NEEDED. IN CASE OF EMERGENCY, THE PRIMARY CONTACT FOR THE PROJECT WILL BE THE RLD OR CONTRACTOR ON-SITE. THE CONTRACTOR WILL BE DETERMINED AT THE TIME THE CONTRACT IS AWARDED. TIN ADDITION THE OWNER MAY BE CONTACTED, MR. ALAN TAYLOR. UPON COMPLETION OF THE PROJECT, THE OWNER WILL BE RESPONSIBLE FOR SITE MAINTENANCE.

DESCRIPTION DUROMAXX IS A REINFORCED POLYETHYLENE PIPE WITH A SMOO TH WATERWAY WALL AND EXTERIOR PROFILE THAT IS REINFORCED WITH HIGH STRENGTH GALVANIZED STEEL RIBS. THE CONTINUOUS REINFORCING RIBS ARE COMPLETELY ENCASED WITHIN THE POLYETHYLENE PROFILE. DUROMAXX IS MANUFACTURED USING A HELICAL WINDING PROCESS THAT RESULTS IN A CONTINUOUSLY FUSION WELDED CIRCUMFERENTIAL LAP SEAM. THE PIPE PROFILE IS MANUFACTURED USING A HIGH QUALITY PRESSURERATEDTHERMOPLASTIC MEETING THE REQUIREMENTS OF ASTM F2562 "STANDARD SPECIFICATION FOR STEEL REINFORCED TttERMOPLASTIC RIBBED PIPE AND FITTINGS FOR NON -PRESSURE DRAINAGE AND SEWERAGE'. FOR THE PURPOSE OF HYDRAULIC DESIGN, THE RECOMMENDED MANNING'S "N" VALUE SHALL BE 0.012 FOR PIPE DIAMETERS INCLUDED WITHIN THIS SPECIFICATION.
