Notify owner, Engineer and Land Quallly Section prior to beginning construction. b.Clearing or grading shall begin at low points, points of outfa!l release or at other locations where sediment measures are shown on the plan, and the sediment control devices (sediment traps, silt fences, diversion stormwater treatment areas, etc.) shall be Installed before or simultaneously with the disturbance of any area draining to the device. c. Limits of disturbance will be according to the plan as shown. Silt fence sholl be installed Immedlate/y after disturbance Ilt fence shall be maintained until the disturbed area is stabilized completely. Silt fences are shown based on topographic Information /n the locations expected to be needed to trap sediment prior to entering down slope areas. Actual locations of Installation shall be adjusted to the actual physical on site topogropohy.That Is, where silt fence Is not shown on the plan but the actual topography reflects a downward slope�sllt fence shall be Installed Where the actual topography reflects an upward slope silt fence is not required. d. Construct infiltration basin. See Infiltration basin detall for more Information. e. Strip and stockpile topsol/ for later use. Rough grade site. f.Install catch basins, storm draln pipes and drainage swales.Immediately construct sediment traps and rock check dams where shown.Wlthin l5 days, temporary seed swages If not /n final condition or permanent seed and Install Swale l)ner,lf In fowl condition. g. Within /5 days upon completion of grading, install temporary or permanent seeding and mulching. h Fine grade drives and parking area, place CABC over compacted subgrade I. Establish groundcover on exposed slopes within /5 calendar days following completion of any phase of grading. J. Contractor must conduct and pass a proof roll test, on the subrade proor to Installing stone. The proof roll test shall be conducted In the presence of the Engineer. k. Seed, fertilize and mulch all disturbed areas within 15 days of conpleting any phase of the grading work.App/y temporary seeding If area Is o be disturbed again and permanent If areas have been final graded and accepted by the engineer and owner. 2. Seeding SpeciflooNaxs: Apply Ilene and fertilizer and work Into seed bed, seed mixture shall be distributed uniformty and convened with a clean straw mulch Mulch shall be crimped or tacked to help hold In place.

Contractor is responsible for malntalning all erosion control measures and shall amend measures as required to prevent accelerated erosion from taking place on this site, until site Is restab1//zed and accepted by the engineer and owner. 4. Upon restablllzation of all disturbed areas and swales, contrractor shall remove all temporary erosion control facilities and grade, grass, mulch and restablllze the areas. t Elev.

Notify Engineer 48 hours prior to beginning construction. 2.The infiltration basin requires Inspection during construction and upon completion requires certification of construction to the North Carolina Division of Water Quality by a North Carolina Professional Engineer. 3.The Infiltration basin Is not to be used as a sediment trap. Stormwater shall be diverted away from the Infiltration basin until contributing watersheds are completely stabilized 4.Excavate and grade the side slopes of the basin to elevation 4130 5. Immediate upon excavation, silt fences shall be placed at the bottom of the basin sides and remain In place until the side slopes are stabilized. 6.Contractor shall measure basin to ensure correct size. 7.Install Inlet pipes and flared end sections. 8.Install filter cloth barrier. 9. Place 6' clean sand over filter cloth barrier at basin bottom to elevation 3820. IO.Sod side slopes. It. Install r1p rap level spreaders. 12.Place slit fence at top of basin to prevent erosion. l3.For additional Information, see stormwater management permit.
