Without the wire support fence, post shall not exceed 6 feet. When extra strength filter fabric and closer post spacing are used, the wire mesh support fence may be eliminated. In such a case, the filter fabric is :.: tapled or wired directly' to the post. Sediment must be removed when deposits reach approximately one-half the height of the barrier. Any sediment deposits remaining in place after the silt fence or filter barrier is no longer required shall be dressed to conform with the existing grade, prepared and seeded. Under no circumstances should silt fence be constructed in live steams. Silt fence shall be removed upon completion of the project. E & S UT/LSTY NOTES All excavated material is to be place on the uphill side of trench. A// storm and sanitary sewer lines not in streets are to be mulched and seeded within 7 days after backfill, no more than 500 feet are to be open at one time. Construction access roads shall be located on the uphill side of the trench or over the trench whenever possible. All construction discharge water shall be adequately filtered to remove silt prior to discharge into waterways and wetlands. All streams crossing and stream diversions require environmental approval prior to any instreGm Construction (see IN -STREAM NOTES). SEED/NO NOTES All stabilization/seeding will be accomplished in accordance with the Virginia Erosion and Sedimentation Control Handbook. Any disturbed area not paved, sodded, or built upon, will have a minimum of 1007 vegetative cover prior to final inspection, and in the opinion of the Environmental Engineer will be mature enough to control soil erosion satisfactorily and survive severe weather conditions. Stream diversion areas, waterways, banks and related areas will be seeded and mulched immediately after work in watercourse is completed.

Temporary soil stabilization shall be applied within 7 days to denuded areas that may not be at final grade but will remain dormant (undisturbed) for longer than 30 days. Permanent stabilization shall be applied to areas that are to be left dormant for more than 1 year. Electric power, telephone, and gas supply trenches are to be compacted, seeded and mulched within 7 days after backfill. All temporary earth berms, diversions, and silt dams are to be mulched and seeded for vegetative cover immediately after grading. Straw Or hay mulch is required. The same applies to all stockplles, on site as well as soli/ (intentionally transported from the project site. All fertilizing, liming, seeding and mulching will be done at the following rates unless otherwise specified on the plans: Lime and fertilizer needs should be determined by soil tests. Soil tests may be performed by the Cooperative Extension Service Soil Testing Laboratory at VPI&SU, or by a reputable commercial laboratory. Information concerning the State Soil Testing Laboratory is available from county extension agents. Under unusual conditions where it is not possible to obtain a soil test, the following soil amendments will be applied: Lime Piedmont and Appalachian Region: 2 tons/acre pulverized agricultural grade limestone (90 lbs./1000 0). Note: An agriaul Ural graoe of limestone should always be used. eTSI% Mixed grasses and legumes: 1000 tbs./acre 10-20-10 or equivalent nutrients (23 lbs./ 1000 ft.2).

SILT FENCE: A temporary sediment barrier constructed of posts, filter fabric and, in some cases, a wire support fence, placed across or at the toe of a slope or in a minor drainage way to intercept and detain sediment and decrease flow velocities from drainage areas of limited size; applicable where sheet and rill erosion or small concentrated flows may be a problem. Maximum effective life of 6 months. STDRM D : The installation of various kinds of sediment trapping measures around drop inlets or curb inlet structures prior to permanem —,abilization of the disturbed area, limited to drainage areas not exceeding one acre, and not intended to control large, concentrated stormwater flows. CUL MRT INLET PROM-0-TON: A sediment filter located at the inlet to storm sewer culverts which prevents sediment from entering, accumulating in and being transferred by the culvert. It also provides erosion control at culverts during the phase of a project where elevations and drainage patterns are changing, causing original control ;measures to be ineffective. 1EMPORARYI71YERSION DIKE: A ridge of compacted soil constructed at the top or base of a sloping .disturbed area *6ch diverts off -site runoff away from unprotected slopes and to a stabilized ou tlet, or to divert sediment - laden runoff to a sediment trapping structure. Maximum effective life is 18 months. TEMPORARY FILL DIVERSLON: A channel with a supporting ridge on the lower side, constructed along the top of an active earth fill constructed in order to divert runoff away from the unprotected fill slope to a stabilized outlet or sediment trapping structure; applicable where the area at the top of the fill drains toward the exposed slope and continuous fill operations make the use of a TEMPORARY DIVEPSION DIKE infeasible; maximum effective life is one week. 'EMPOgAM, SEDIMENT. TRAP : A small ponding area, formed by constructing an earthen embankment vuith a stone outlet across a drainage swale, to detain sedimerat-laden runoff fi4m small disturbed areas for enough time to allow most of the suspended solids to settle out. Maximum effective life is 18 months. J.WQRARY SM�ENT BASIN: A, temporary barrier or dam with a controlled stormwater release structure which is formed by constructing an embankment of compacted soil across � drainageway. It is used to detain sediment -laden runoff from drainage areas 3 acres or greater for enough time to allow most of the suspended solids to .tittle out. It can be constructed only where there is sufficient space and alipropriate topography. Maximum effective life is 18 months unless designed as a permanent pond by a qualified pfpfessional. The installation of riprap channel sections and/or stilling basins below storm. drain outlets t.,°.) reduce erosion and under -cutting from scouring at outlets .and to reduc,': glow velocities before stormwater enters receiving channels below these onfets. R : A permanent, erosion -rest.,&, ii ground cover of large, loose, angular stone installed wherever soil conditions, water turbulence and velocity, expected vegetative cover, etc., are such that soul may erode under design :flow conditions. R_QCK CHECK DAMS: Small, temporary stone darns constructed across a drainage ditch to reduce the velocity of clloicentrated flows, reducing erosion of the swale or ditch. Limited to use open chau eels which drain 10 acres or less; should not be used in live streams. TCIPSOILING: Preserving and using topsoil to provide a suitable growth medium for vegetation used to stabilize disturbed areas. Applicable where preservation or importattion of topsoil is most cost-effective method of providing a suitable growth medium; no., recommended for slopes steeper than 2:1 unless additional measures nv, taken to prevent sloughing and erosion. "I:F1PO9ARX SEED_IN_G: Establishment of temporary vegetative cover on disturbed areas that will mot be brought to final grade for periods of 30 days to one year by seeding wiith appropriate rapidly -growing plants. PERMANENT SEEDINIG: Establishment of perennial vegetative •cover by planting seed on rough -graded areas that will not be brought to final grade for a year or more or where permanent, long-lived vegetative cover is needed on fine -graded areas. fgMRV UQN AND PROU1,MON: Protecting existing trees from mechanical and other injury during land -disturbing and construction activity to ensure the surwival of desirable trees where they will be effective for erosion and sediment control and provide other environmental and aesthetic benefits. DUST CONTROL Rediucing surface sad4 air movement of dust during land disturbance, demolition for constructioi activities in areas subject to dust problems in order to prevent soil loss aid reduce the presence of potentially harmful airborne substance.
