REVEGETATION PROCEDURES ALL AREAS DISTURBED DURING CONSTRUCTION WILL BE REVEGETATED ACCORDING TO THE FOLLOWING CRITERIA, DURING CONSTRUCTION, EROSION WHICH MAY POSE A THREAT TO SURROUNDING PROPERTIES OR WATERWAYS WILL BE CONTAINED THROUGH THE USE OF TEMPORARY EROSION CONTROL MEASURES AS DEEMED NECESSARY TO COMPLY WITH THE N.P.D.E.S. REVEGETATION OF DISTURBED AREAS SHALL COMMENCE IN THE FALL, PRIOR TO THE FIRST MAJOR SNOWFALL, OR EARLY SPRING IF SITE CONDITIONS ALLOW. EROSION CONTROL MEASURES ARE AIMED AT CONTROLLING/CONFINING SEDIMENT WITHIN OR NEAR THE AREA OF DISTURBANCE, THE LONG TERM STABILITY OF THESE AREAS WILL DEPEND ON THE ESTABLISHMENT OF APPROPRIATE GROUND COVER VEGETATION, THE PRIMARY GOAL OF THE REVEGETATION EFFORT IS TO PROTECT WATER QUALITY WHICH WILL REQUIRE A STURDY GROUND COVER AS SOON AS POSSIBLE. FOLLOWING ARE STANDARDS WHICH HAVE BEEN ESTABLISHED FOR REVEGETATION APPLICATION TECHNIQUES: 1. ALL TOPSOIL SHALL BE SALVAGED FROM DISTURBED AREAS, STOCKPILED AND RE—SPREAD PRIOR TO REVEGETATION. TOPSOIL SHOULD NOT BE RE—SPREAD ON AREAS OF THE SITE PROPOSED FOR FUTURE BUILDING, THE FINISHED SOIL SURFACE SHALL BE LEFT IN AN IRREGULAR, SCARIFIED CONDITION WHICH MAXIMIZES MOISTURE RETENTION ON THE SLOPE. 2. WHERE SLOPE ALLOWS, SEED SHALL BE DRILLED OR OTHERWISE MECHANICALLY INCORPORATED INTO THE SOIL ("FARMED"). WHERE STEEPNESS OF SLOPE RESTRICTS EQUIPMENT ACCESS, SEED SHALL BE HYDRAULICALLY APPLIED AND FOLLOWED BY APPLICATION OF HYDRAULICALLY APPLIED MULCH OR STRAW, STRAW MULCH SHALL BE SECURED IN PLACE WITH A HYDRAULICALLY APPLIED TACKIFIER, 3. SLOPES WITH GRADIENTS OF 2:1 OR STEEPER SHALL BE HYDRAULICALLY SEEDED, STRAW MULCHED AND PROTECTED BY PLACEMENT OF EROSION BLANKET (JUTE, EXCELSIOR OR SIMILAR ORGANIC PRODUCT), STRAW TACKIFIER IS NOT REQUIRED WHEN EROSION BLANKET IS USED. 4. THE EXPOSED SLOPE WOULD BE PREPARED WITH MINI BENCHES. TOPSOIL WOULD THEN BE SPREAD OVER THE SLOPE, SEEDED AND COVERED WITH STRAW. EROSION CONTROL BLANKET WOULD THEN BE TACKED INTO THE HILLSIDE COVERING ALL THE SEEDING, IF EXISTING MOISTURE CONDITIONS INDICATE THE REQUIREMENT FOR IRRIGATION, THEN EITHER DRIP IRRIGATION OR MINI—SPRAY IRRIGATION WOULD BE USED. 5. REVEGETATION WILL BE CONSIDERED SUCCESSFUL WHEN THE CONTRACTOR HAS ESTABLISHED A DESIRABLE PERENNIAL VEGETATION (SEED MIX) BY THE END OF THE SECOND GROWING SEASON SUFFICIENT IN COVER AND CAPABLE OF RENEWING ITSELF TO ADVANCE TO THE ACCEPTABLE STAGE OF REVEGETATION AND THE DISTURBED AREA IS CONSIDERED STABILIZED AND EROSION CONTROLLED.
