SCALE: DATE:PROUDLY SERVING VIRGINIA & WEST VIRGINIAOFFICES IN: WINCHESTER, VA & MARTINSBURG, WV06/01/2022 MINIMUM CONSTRUCTION STANDARDS An erosion and sediment control program adopted with this plan must be consistent with the VSECH for 9VAC25-840-40 minimum standards: 1.Permanent or temporary soil stabilization shall be applied to 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 14 days. Permanent stabilization shall be applied to areas that are to be left dormant for more than one year. 2.During construction of the project, soil stock piles and borrow areas shall be stabilized or protected with sediment trapping measures. The applicant is responsible for the temporary protection and permanent stabilization of all soil stockpiles on site as well as borrow areas and soil intentionally transported from the project site. 3.A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieved that is uniform, mature enough to survive and will inhibit erosion. 4.Sediment basins and traps, perimeter dikes, sediment barriers and other measures intended to trap sediment shall be constructed as a first step in any land-disturbing activity and shall be made functional before upslope land disturbance takes place. 5.Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions immediately after installation. 6.Sediment traps and sediment basins shall be designed and constructed based upon the total drainage area to be served by the trap or basin. a.The minimum storage capacity of a sediment trap shall be 134 cubic yards per acre of drainage area and the trap shall only control drainage areas less than three acres. b.Surface runoff from disturbed areas that is comprised of flow from drainage areas greater than or equal to three acres shall be controlled by a sediment basin. The minimum storage capacity of a sediment basin shall be 134 cubic yards per acre of drainage area. The outfall system shall, at a minimum, maintain the structural integrity of the basin during a 100-year storm of 24-hour duration. Runoff coefficients used in runoff calculations shall correspond to a bare earth condition or those conditions expected to exist while the sediment basin is utilized. 7.Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that are found to be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilizing measures until the problem is corrected. 8.Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or permanent channel, flume or slope drain structure. 9.Whenever water seeps from a slope face, adequate drainage or other protection shall be provided. 10.All storm sewer inlets that are made operable during construction shall be protected so that sediment-laden water cannot enter the conveyance system without first being filtered or otherwise treated to remove sediment. 11.Before newly constructed stormwater conveyance channels or pipes are made operational, adequate outlet protection and any required temporary or permanent channel lining shall be installed in both the conveyance channel and receiving channel. 12.When work in a live watercourse is performed, precautions shall be taken to minimize encroachment, control sediment transport and stabilize the work area to the greatest extent possible during construction. Nonerodible material shall be used for the construction of causeways and cofferdams. Earthen fill may be used for these structures if armored by nonerodible cover materials. 13.When a live watercourse must be crossed by construction vehicles more than twice in any six-month period, a temporary vehicular stream crossing constructed of nonerodible material shall be provided. 14.All applicable federal, state and local requirements pertaining to working in or crossing live watercourses shall be met. 15.The bed and banks of a watercourse shall be stabilized immediately after work in the watercourse is completed. 16.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 opened 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 or off-site property. d.Material used for backfilling trenches shall be properly compacted in order to minimize erosion and promote stabilization. e.Restabilization shall be accomplished in accordance with this chapter. f.Applicable safety requirements shall be complied with. 17.Where construction vehicle access routes intersect paved or public roads, provisions shall be made to minimize the transport of sediment by vehicular tracking onto the paved surface. Where sediment is transported onto a paved or public road surface, the road surface shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This provision shall apply to individual development lots as well as to larger land-disturbing activities. 18.All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or after the temporary measures are no longer needed, unless otherwise authorized by the VESCP authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. 19.Properties and waterways downstream from development sites shall be protected from sediment deposition, erosion and damage due to increases in volume, velocity and peak flow rate of stormwater runoff for the stated frequency storm of 24-hour duration in accordance with the following standards and criteria. Stream restoration and relocation projects that incorporate natural channel design concepts are not man-made channels and shall be exempt from any flow rate capacity and velocity requirements for natural or man-made channels: a.Concentrated stormwater runoff leaving a development site shall be discharged directly into an adequate natural or man-made receiving channel, pipe or storm sewer system. For those sites where runoff is discharged into a pipe or pipe system, downstream stability analyses at the outfall of the pipe or pipe system shall be performed. b.Adequacy of all channels and pipes shall be verified in the following manner: (1)The applicant shall demonstrate that the total drainage area to the point of analysis within the channel is one hundred times greater than the contributing drainage area of the project in question; or (2)(a) Natural channels shall be analyzed by the use of a two-year storm to verify that stormwater will not overtop channel banks nor cause erosion of channel bed or banks. (b)All previously constructed man-made channels shall be analyzed by the use of a 10-year storm to verify that stormwater will not overtop its banks and by the use of a two-year storm to demonstrate that stormwater will not cause erosion of channel bed or banks; and (c)Pipes and storm sewer systems shall be analyzed by the use of a 10-year storm to verify that stormwater will be contained within the pipe or system. c.If existing natural receiving channels or previously constructed man-made channels or pipes are not adequate, the applicant shall: (1)Improve the channels to a condition where a 10-year storm will not overtop the banks and a two-year storm will not cause erosion to the channel, the bed, or the banks; or (2)Improve the pipe or pipe system to a condition where the 10-year storm is contained within the appurtenances; (3)Develop a site design that will not cause the pre-development peak runoff rate from a two-year storm to increase when runoff outfalls into a natural channel or will not cause the pre-development peak runoff rate from a 10-year storm to increase when runoff outfalls into a man-made channel; or (4)Provide a combination of channel improvement, stormwater detention or other measures which is satisfactory to the VESCP authority to prevent downstream erosion. d.The applicant shall provide evidence of permission to make the improvements. e.All hydrologic analyses shall be based on the existing watershed characteristics and the ultimate development condition of the subject project. f.If the applicant chooses an option that includes stormwater detention, he shall obtain approval from the VESCP of a plan for maintenance of the detention facilities. The plan shall set forth the maintenance requirements of the facility and the person responsible for performing the maintenance. g.Outfall from a detention facility shall be discharged to a receiving channel, and energy dissipators shall be placed at the outfall of all detention facilities as necessary to provide a stabilized transition from the facility to the receiving channel. h.All on-site channels must be verified to be adequate. i.Increased volumes of sheet flows that may cause erosion or sedimentation on adjacent property shall be diverted to a stable outlet, adequate channel, pipe or pipe system, or to a detention facility. j.In applying these stormwater management criteria, individual lots or parcels in a residential, commercial or industrial development shall not be considered to be separate development projects. Instead, the development, as a whole, shall be considered to be a single development project. Hydrologic parameters that reflect the ultimate development condition shall be used in all engineering calculations. k.All measures used to protect properties and waterways shall be employed in a manner which minimizes impacts on the physical, chemical and biological integrity of rivers, streams and other waters of the state. l.Any plan approved prior to July 1, 2014, that provides for stormwater management that addresses any flow rate capacity and velocity requirements for natural or man-made channels shall satisfy the flow rate capacity and velocity requirements for natural or man-made channels if the practices are designed to (i) detain the water quality volume and to release it over 48 hours; (ii) detain and release over a 24-hour period the expected rainfall resulting from the one year, 24-hour storm; and (iii) reduce the allowable peak flow rate resulting from the 1.5, 2, and 10-year, 24-hour storms to a level that is less than or equal to the peak flow rate from the site assuming it was in a good forested condition, achieved through multiplication of the forested peak flow rate by a reduction factor that is equal to the runoff volume from the site when it was in a good forested condition divided by the runoff volume from the site in its proposed condition, and shall be exempt from any flow rate capacity and velocity requirements for natural or man-made channels as defined in any regulations promulgated pursuant to § 62.1-44.15:54 or 62.1-44.15:65 of the Act. m.For plans approved on and after July 1, 2014, the flow rate capacity and velocity requirements of § 62.1-44.15:52 A of the Act and this subsection shall be satisfied by compliance with water quantity requirements in the Stormwater Management Act (§ 62.1-44.15:24 et seq. of the Code of Virginia) and attendant regulations, unless such land-disturbing activities are in accordance with 9VAC25-870-48 of the Virginia Stormwater Management Program (VSMP) Regulation or are exempt pursuant to subdivision C 7 of § 62.1-44.15:34 of the Act. n.Compliance with the water quantity minimum standards set out in 9VAC25-870-66 of the Virginia Stormwater Management Program (VSMP) Regulation shall be deemed to satisfy the requirements of this subdivision 19. EROSION AND SEDIMENT CONTROL NARRATIVE Description: THE PROJECT WILL CONSIST OF THE CONSTRUCTION OF A WHOLESALE/OFFICE BUILDING IN THE STONEWALL INDUSTRIAL PARK. THE SITE IS LOCATED ON THE CORNER OF MCGHEE RD AND LAKESVILLE CIRCLE. THE SITE CONSISTS OF CONSTRUCTION OF A 20,970 SQFT BUILDING, 1.1 ACRES OF PAVED PARKING AREAS, AND ASSOCIATED UTILITIES ON 3.39 ACRES. A TOTAL OF 0.98 ACRES WILL BE DISTURBED DURING CONSTRUCTION. Date of construction: CONSTRUCTION WILL BEGIN UPON PLAN APPROVAL AND WILL TAKE APPROXIMATELY SIX (6) MONTHS TO COMPLETE. Existing site conditions: THE PROPOSED SITE IS GENERALLY LOCATED ON TOP OF AN EASTERLY RIDGE. MOST OF THE SITE IS COVERED WITH OPEN GRASS AREAS WITH THE REMAINDER BEING HARDWOODS. THE SITE IS DIVIDED INTO GENERALLY TWO DRAINAGE AREAS SLOPING AT AVERAGE OF 2.1% TO THE EAST. Adjacent areas: THE SITE IS BOUNDED TO THE NORTH BY MCGEE ROAD. ON THE EAST BY LAKESVILLE CIRCLE, ON THE SOUTH BY A 36,000 SQFT WAREHOUSE, AND ON THE WEST BY AN UNDEVELOPED ZONED M-1 PROPERTY. Offsite areas: THERE ARE NO OFFSITE DISTURBANCES ASSOCIATED WITH THIS DEVELOPMENT. Soils: THE EXISTING SOILS CONDITIONS WERE OBTAINED FROM THE USDA SOIL SURVEY. THE PREDOMINANT SOIL ON THE SITE IS FREDERICK-POPLIMENTO LOAM (14B) AND HAS A MODERATE EROSION HAZARD. Critical areas: No critical areas are identified with this project. Erosion And Sediment Control Measures: Unless otherwise indicated, all vegetative and structural erosion and sediment control measures shall be constructed and maintained according to the minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook. Structural Measures: Phase I: Install Temporary Construction Entrance with Wash Rack (3.02) as shown on the plans to minimize sediment carried onto roadway. Install silt fence (3.05) and super silt fence as shown on the plans to intercept and detain small amounts of sediment from disturbed areas during construction in order to prevent sediment from leaving the site. Install storm drain inlet protection (3.07) as shown on plans to prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed area. Temporary seeding (3.31) and/or permanent seeding (3.32) shall be placed on all critical slopes (3:1 or greater) and as needed to stabilize disturbed areas. Soil stabilization blankets & matting (3.36) shall be installed over steep 3:1 or greater cut and fills slope which have been brought to final grade and seeded to protect from rill and gully erosion. Phase II: Phase I controls shall remain into Phase II for the duration of the project or until drainage area is stabilized. Outlet protection (3.18) shall be installed on all outlets as shown on the plan sheets. Fill slope surface shall be left in a roughened condition to reduce erosion, see Plate 3.29-4. Contractor shall redirect the concentrated flow away from the fill slope by installing diversion dike and divert the runoff to sediment traps or sediment basins. Temporary seeding (3.31) and/or permanent seeding (3.32) shall be placed on all critical slopes (3:1 or greater) and as needed to stabilize disturbed areas. Vegetative Measures: Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven (7) days to denuded areas that may not be at final grade but will remain dormant for longer than fourteen (14) days. Permanent soil stabilization shall be applied to all areas that are to be left dormant for more than one year. Topsoil that has been stockpiled shall be surrounded with silt fence and protected by mulch and/or temporary vegetation immediately after grading. All earth berms, diversions and sediment trap embankments are to be machine-compacted, seeded and mulched (hay mulch or straw) for temporary and/or permanent vegetative cover immediately after construction Erosion control mats shall be installed over steep (3:1) cut and fills slope which have been brought to final grade and seeded to protect from rill and gully erosion. Management Strategies: Construction shall be sequenced such that grading operations will begin and end as quickly as possible. The site superintendent shall be responsible for the installation and maintenance of all erosion and sediment control measures. Maintenance of these measures throughout the project is critical to the effectiveness of the program. After areas above controls have been stabilized, the controls shall be cleaned up and removed. Electric power, telephone, storm, sanitary, water & gas supply trenches are to be compacted, seeded and mulched within five (5) days after backfilling. No more than 500 feet are to be open at any one time. All cut and fill slopes are to be seeded and mulched within five (5) days of completion of grading. Drainage swales shall be stabilized with check dams until vegetation has been well established, at which time the check dams shall be removed. Devices listed above are considered minimum erosion and sediment controls. Additional control measures may be necessary due to contractor phasing or other unforeseen conditions. It is the contractor's responsibility to provide additional measures to those shown, as needed, in order to control erosion and contain sediment on site. All measures shall be installed according to the standards and specifications in the Virginia Erosion and Sediment Control Handbook. Stormwater Management: Increased runoff from this development will be controlled by the Project's stormwater management facilities. Maintenance Program: All control measures shall be inspected daily by the site superintendent or his representative and within 24 hours after any storm event greater than 0.5 inches of rain per 24-hour period. Any damaged structural measures are to be repaired by the end of the day. Seeded areas shall be checked regularly to ensure that a good stand of grass is maintained. All areas shall be fertilized and reseeded as needed until grass is established. Trapped sediment is to be removed as required to maintain 50% trap efficiency and disposed of by spreading on site. Inlet protection shall be checked regularly for sediment build-up. If the gravel outlet is clogged by sediment, it shall be removed and cleaned or replaced immediately. The contractor is responsible for keeping existing public roads in a clean, dust and mud free, condition at all times. Erosion and sediment control program: Phase I 1.Hold pre-construction meeting on site with inspector. 2.Install construction entrance. 3.Clearing and grubbing for sediment control devices only 4.Placement of sediment control devices. 5.Obtain inspector's approval prior to beginning grading operations. 6.Clear and grub main area of site protected by installed E&S controls.

THE 3.3 ACRE SITE WAS EVALUATED FOR STORMWATER QUANTITY CONTROL. QUALITY CONTROL WAS NOT ANALYZED DUE TO THE SITE BEING UNDER ONE ACRE OF DEVELOPMENT/IMPERVIOUS. STORMWATER QUALITY (BMP): THE VIRGINIA RUNOFF REDUCTION METHOD FOR NEW DEVELOPMENT WORKSHEET V3.0-2011 STANDARDS AND SPECIFICATIONS WAS NOTE USED TO VERIFY COMPLIANCE OF THE WATER QUALITY CONTROL REQUIREMENTS. THE SITE IS LESS THAN ONE ACRE OF DEVELOPMENT OR IMPERVIOUS THEREFORE DOES NOT MEET THE REQUIRED AREA. STORMWATER QUANTITY (SWM): THE STORM WATER QUANTITY REQUIREMENTS (CHANNEL AND FLOOD PROTECTION) WERE MET BY THE PROPOSED SWM POND #1. THE ENERGY BALANCE EQUATION WAS USED TO DETERMINE ADEQUATE CHANNEL PROTECTION WAS PROVIDED IN THE 1 YEAR STORM EVENT. THE FLOOD PROTECTION REQUIREMENT WAS SATISFIED BY THE 10 YEAR STORM EVENT IN THE POST DEVELOPED CONDITION BEING LESS THAN THE PRE-DEVELOPED. THE EXISTING POND WILL BE REVISED TO MEET THE NEW REQUIREMENTS OF THE BUILDING ADDITION. NOTES: HYDROCAD SOFTWARE VERSION 10 BUILD 15 WAS USED TO ROUTE THE STORMWATER MANGEMENT FACILITY AND ALL DRAINAGE AREAS TO VERIFY THE SWM REQUIREMENTS WERE MET.
