The plan approving authority must be notified one week prior to the pre-construction andnce, one one weekweek priorrrtorto the the finaloiinspection of land 2. All erosion and sediment control measures will be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook and Virginia Regulations VR 625-02-00 Erosion and Sediment Control Regulations. 3. All erosion and sediment control measures are to be placed prior to or as the first step in clearing. 4. A copy of the approved erosion and sediment control plan shall be maintained on the site at all times. 5. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but not limited to, off-site borrow or wasted areas), the contractor shall submit a supplementary erosion control plan to the owner for review and approval by the plan approving authority. 6. The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion and sedimentation as determined by the plan approving authority. 7. All disturbed areas are to drain to approved sediment control measures at all times during land disturbing activities and during site development until final stabilization is achieved. B. During dewatering operations, water will be pumped into an approved filtering device. 9. The contractor shall inspect all erosion control measures periodically and after each runoff -producing rainfall event. Any necessary repairs or cleanup to maintain the effectiveness of the erosion control devices shall be made immediately. 10. All fill material is to be taken from an approved, designated borrow area. 11. All waste material is to be taken an approved waste area. Earth fill shall be inert materials only, free of roots, stumps, wood, rubbish, and other debris. 12. Borrow or waste areas are to be reclaimed within 7 days of completion per Zoning Ordinance section 5.1.28. 13. All inert materials shall be transported in compliance with section 13-301 of the Code of Albemarle. 14. Borrow, fill or waste activity involving industrial -stype power equipment shall be limited to the hours of 7:00am to 9:00pm. 15. Borrow, fill or waste activity shall be conducted in a safe manner that maintains lateral support in order to minimize any hazard to persons, physical damage to adjacent land and improvements, arnd damage to any public street caused by slides, sinking, or collapse. 16. The developer shall reserve the right to install, maintain, remove or convert to permanent stormwater management facilities where applicable, all erosion control measures required by this plan regardless of the sale of any lot, unit, building or other portion of the property. 17. Temporary stabilization shall be temporary seeding arnd mulching. Seeding is to be at 75 lbs/acre, and in the months of September to February to consist of a 50/50 mix of Annual Ryegrass and Cerreal Winter Rye, or in March and April to consist of Annual Rye, or May through August to consist of German Millet. Straw mulch is to be applied at 80 lbs/100 sf. Alternatives are subject to approval by the County erosion control in sp,,.,tor. 18. Permanent stabilization shall be lime and fertilizer, permanent seeding, and mulch. Agricultural grade limestone shall be applied at 90 lbs/1000 sf, incorporated into the top 4-6 inches of soil. FertilAzcr shall be applied at 1000 lbs/acre and consist of a 10-20-10 nutrient mix;. Permanent seeding shall be applied at 180 lbs/acre and consist of 95% Kentucky 91 or Tall Fescue and 0-5% Perennial Ryegras or Kentucky Bluegrass. Straw mu:,ch is to be applied at 80 lbs/100 sf. Alternatives are subject to approval by the County erosion control inspector. 19. Maintenance: All measures are to be inspected weekly and after each rainfall. Any damage or clogging to structural measures is to be repaired immediately. Silt traps are to be cleaned when 50% of the wet storage volume is filled with sediment. All seeded areas are to be reseeded when necessary to achieve a good stand of grass. Silt fence and diversion dikes which are collecting sediment to half their height must be cleaned and repaired irmmediately. 20. All temporary erasion and sediment control measures are to be removed within 30 days of final site stabilization, when measures are no longer needed, subject to approval by the County erosion control inspector. ADDITIONAL EROSION AND SEDIMENT CONTROL NOTES: * DUST CONTROL Measures for dust control, as stated in section 3.39 of the Virginia Erosion and Sediment Control Handbook, shall be implemented cduring grading and construction in order to prevent surface and air movicement of dust from exposed soil surfaces and to reduce the presence of airborne substances. * TOPSOIL STOCKPILING All topsoil stockpile locations shall be in areas thiat are protected by proposed sediment trapping measures. Any other stocklpile areas shall require a plan amendment. * CONSTRUCTION ROAD STABILIZATION All roads will be subject to construction road stabilization at the discretion of the Erosion Control Officer once the roads have been brought to finish grade. * ALL VEGETATIVE PRACTICES To include permanent and temporary seeding, mulching and topsoiling -- All denuded area shall be controlled by vegetative practices as detailed in the narrative. Topsoiling, mulching, and any other measurres to enhance growth and protect against erosion are recommended. * DIVERSION DIKES The diversion dikes shown on this plan are intended -to either: divert silt laden water toward a trap, divert clean water, away firom a trap, or to keep clean water from crossing a disturbed area and thus (becoming contaminated. * MS -16. UNDERGROUND UTILITY CONSTRUCTION Underground utility lines shall be installed in accordance with the following standards, in addition to other applicable criteria: A. No more than 500 linear feet of trench may be olpened at one time. B. Excavated material shall be placed on the uphill side of trenches. C. Effluent from dewatering operations shall be filtered or passed through an approved sediment trapping device, or both, and discharged in a manner that does not adversely affect flowing streams ior off-site property. D. Material used for backfilling trenches shall be properly compacted in order to minimize erosion and to promote stabilization. E. Restabilization shall be accomplished in accordance with these regulations F. Applicable safety regulations shall be Complied with. * THIS PLAN REPRESENTS ONLY ONE PART OF THE APPROVED EROSION AND SEDIMENT CONTROL PERMIT. CONTRACTOR MUST ALSO IMPLEMENT THE PRACTICE'S IN THE APPROVED EROSION AND SEDIMENT CONTROL NARRATIVE TO COMPLY WITH THE PERMIT. CONTRACTOR MUST KEEP AN APPROVED COPY OF THE PLAN AND NARRATIVE ON THE JOB SITE AT ALL TIMES. GENERAL CONSTRUCTION NOTES FOR STORMWATER MANAGEMENT PLANS 1. Both dams constructed with fill are to be within 95% of maximum dry density and 2% of optimum moisture content. A licensed geotechnical engineer shall be in charge of any design considerations associated with the dams and shall be present to approve any fill material used in the construction of the dams. 2. Pipe and riser joints are to be watertight within stormwater management facilities. 3. For temporary sediment traps or basins which are to be converted to permanent stormwater management facilities; conversion is not to take place until the site is stabilized, and permission has been obtained from the County erosion control inspector. 111014 W 1 10 SILT FENCE CULVERT INLET PROTECTION SILT FLOW -TOE OF FILL x DISTANCE IS 6' MINIMUM IF FLOW IS TOWARD EMBANKMENT * OPTIONAL STONE COMBINATION 1.0' 1.5' !
