PERMANENT STABILIZATION ALL AREAS DISTURBED BY CONSTRUCTION SHALL BE STABILIZED WITH STRAW AND SEEDING IMMEDIATELY FOLLOWING FINISH GRADING. AREAS WITH SLOPES LESS THAN 2:1, SHALL BE SEEDED WITH KENTUCKY 31 TALL FESCUE IN ACCORDANCE TO STANDARD AND SPECIFICATION 3.32, PERMANENT SEEDING, OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. AREAS WITH SLOPES EQUAL TO OR STEEPER THAN 2:1, SHALL BE SEEDED WITH KENTUCKY 31 TALL FESCUE, RED TOP GRASS, A SEASONAL NURSE CROP AND CROWN VETCH IN ACCORDANCE TO THE STANDARD AND SPECIFICATION 3.32, PERMANENT SEEDING, OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. ANY FERTILIZER AND LIME APPLICATIONS SHALL BE IN ACCORDANCE WITH SOIL TEST RESULTS. ALL SEEDED AREAS WILL BE STRAW MULCHED TO PROTECT AGAINST RILL EROSION AND TO PRESERVE SOIL MOISTURE THAT WILL ENHANCE SEED GERMINATION. CRIMPING, PUNCH ROLLER -TYPE ROLLERS, OR TRACK WALKING MAY BE USED TO INCORPORATE STRAW MULCH INTO THE SOIL ON SLOPES IF STRAW IS TO BE USED. STORMWATER RUNOFF CONSIDERATIONS CALCULATIONS INDICATE THAT THERE WILL BE NO NET INCREASE IN POLLUTANTS AND RUNOFF VOLUME AS A RESULT OF THE THE INCREASE IN IMPERVIOUS AREA. SEE THE STORMWATER MANAGMENT COMPUTATIONS FOR MORE INFORMATION. MAINTENANCE 1. IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED DAILY AND AFTER EACH SIGNIFICANT RAINFALL. 2. THE CONSTRUCTION ENTRANCE SHALL BE CHECKED DAILY FOR SOIL BUILDUP. IF THE ENTRANCE BECOMES CLOGGED WITH SOIL AND FAILS TO, PREVENT TRANSPORTATION OF SOIL ONTO THE ROADWAY, ADDITIONAL STONE, REPLACEMENT OF STONE, OR A WASH -RACK MAY BE REQUIRED,.. 3. SILT FENCE SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND AT LEAST DAILY DURING PROLONGED RAINFALL. CLOSE ATTENTION SHALL BE PAID TO THE REPAIR OF DAMAGED SILT FENCE RESULTING FROM END RUNS AND UNDERCUTTING. SHOULD THE FABRIC ON A SILT FENCE DECOMPOSE OR BECOME INEFFECTIVE PRIOR TO THE END OF THE EXPECTED USABLE LIFE AND THE BARRIER STILL BE NECESSARY, THE FABRIC SHALL BE REPLACED PROMPTLY. SEDIMENT DEPOSITS SHOULD BE REMOVED AFTER EACH STORM EVENT. THEY MUST BE REMOVED WHEN DEPOSITS REACH APPROXIMATELY ONE-HALF THE HEIGHT OF THE BARRIER. ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE SILT FENCE IS NO LONGER REQUIRED SHALL BE DRESSED TO CONFORM WITH THE EXISTING GRADE, PREPARED, AND SEEDED. 4. WHEN APPLICABLE, CLEAN WATER DIVERSION DIKES SHALL BE INSPECTED AFTER EVERY STORM AND REPAIRS MADE TO THE DIKE, FLOW CHANNEL, OUTLET, OR SEDIMENT TRAPPING FACILITY AS NECESSARY. ONCE EVERY TWO WEEKS, WHETHER A STORM EVENT HAS OCCURRED OR NOT, THE MEASURE SHALL BE INSPECTED AND REPAIRS MADE IF NEEDED. DAMAGES CAUSED BY CONSTRUCTION TRAFFIC OR OTHER ACTIVITY MUST BE REPAIRED BEFORE THE END OF EACH WORKING DAY. 5. STORMWATER CONVEYANCE CHANNELS: 5.1. GRASS LINED CHANNELS - DURING THE INITIAL ESTABLISHMENT, GRASS LINED CHANNELS SHOULD BE REPAIRED IMMEDIATELY AND RE-ESTABLISHED IF NECESSARY. AFTER GRASS HAS BECOME ESTABLISHED, THE CHANNEL SHOULD BE CHECKED PERIODICALLY TO DETERMINE IF THE GRASS IS WITHSTANDING FLOW VELOCITIES WITHOUT DAMAGE. IF THE CHANNEL IS TO BE MOWED, IT SHOULD BE DONE IN A MANNER THAT IT WILL NOT DAMAGE THE GRASS. 5.2. IF SEDIMENT IS DEPOSITED IN A GRASS -LINED CHANNEL, IT SHOULD BE REMOVED PROMPTLY TO PREVENT DAMAGE TO THE GRASS. 6. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO ENSURE THAT A GOOD STAND IS MAINTAINED. AREAS SHOULD BE FERTILIZED AND RESEEDED AS NEEDED. 7. A MINIMUM OF 6 INCHES OF TOPSOIL SHALL BE APPLIED TO ALL AREAS REQUIRING PERMANENT SEEDING. CALCULATIONS REFER TO THE WATER QUALITY CALCULATIONS FOR COMPLIANCE WITH THE VRRM REGULATIONS. SEQUENCE OF CONSTRUCTION 1. CONTRACTOR SHALL INSTALL CONSTRUCTION ENTRANCE, TREE PROTECTION, AND SILT FENCE AS FIRST STEP IN CONSTRUCTION. 2. CONTRACTOR SHALL COORDINATE INSPECTIONS, AS REQUIRED BY THE COUNTY OF ALBEMARLE. 3. AFTER RECEIVING ENGINEERING APPROVAL, BEGIN CLEARING, GRUBBING AND FINE GRADING OPERATIONS AS NECESSARY TO ACHIEVE FINAL GRADES. 4. AFTER SITE HAS REACHED SUBGRADE CONDITIONS, BEGIN ROAD STABILIZATION. 5. PERMANENT SOIL STABILIZATION SHALL BE APPLIED TO ALL DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT FOR LONGER THAN 30 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR. 6. AFTER SITE IS STABILIZED AND PERMISSION IS OBTAINED FROM THE EROSION CONTROL INSPECTOR, SILT FENCE AND OTHER EC MEASURES CAN BE REMOVED WITH THE INSPECTORS APPROVAL. e44AT,T H 0.P Christopher C.
