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. 2. During construction of the project, soil stockpiles 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 upstream 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 twenty-five 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 fs corrected. 8. Concentrated runoff shall not flow down curt 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 operations., adequate outlet protection and any required temporary or permanent channel lining shaft 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 regulations pertaining to working in or crossing live watercourses shall be met. 15. The bed and banks of a water course shall be stabilized immediately after work in the watercourse is completed. 16. Underground utility lines shall be installed in accordance with the following standards fn 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 these regulations. f.Applicable safety regulations 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.A11 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 local program 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: SEEDING SCHEDULE (Section 3.32 of VESH) 1.)Topsoil will be spread at a minimum depth of 4 ". 2.)Pulverized agricultural limestone will be incorporated into the soil at a rate of 92 lbs per 1000 square feet (2 tons per acre). 3.)Fertllize with 10-10-10 at a rate of 23 lbs per 1000 square feet (1000 lbs per acre). 4.)Seed mix will consist of 67910 Kentucky 31 Tall fescue and 339yo Red Clover. S)Straw mulch will be applied to all seeded areas at the rate of 3500 lbs per acre and anchored with cutback, or emulsified asphalt applied at a rate of 200 gallons per acre. E & S CONTROL NARRATIVE Project Description This site is located behind the existing ZM Sheetmetal manufacturing facility. The facility is in need of additional parking and this lot is proposed behind the existing parking lot. The area of disturbance is 0.54 acres. Since the new parking lot is part of the larger development, a "Dry Swale" BMP will be placed next to the new parking lot. Existing Site Conditions This site has been kept mowed for several years and is does not drain into the existing stormwater facility. This area drains through existing easements an into Redbud Run. Adjacent Parcels The adjacent parcels are large lot industrial uses Off -Site Areas No off site areas will occur. Soils There is one soil type under this parking lot as determined from the USDA's "Soils Survey of Frederick County, VA. " (#39B) Swimley Silt Loams. This site is classified as a hydrologic soils group C. These soils have medium erodibility and runoff. Geology This area is known for karst conditions; however, no signs of sinkholes or rock outcroppings are present for this area. Since the development is mainly the removal of topsoil and placement of stone and asphalt, compaction of the clay layer will be sufficient. Critical Areas No critical areas present. Erosion Control Measures . Install construction entrance with wash rack, if needed . Install diversion dikes and silt fence . Install the inlet and outlet protection . Grade site and apply compacted gravel to stabilize areas or building and parking . Grade remaining site and install utilities. Seed and stabilize exposed surfaces immediately upon reaching final grade Permanent Stabilization Upon reaching final grade, seed and straw (or hydro -seed) the exposed areas. Silt and other measures may be removed when 85% of the bare ground has a stand of grass. General Erosion and Sediment Control Notes (VESH Table 6-1) ES -1. Unless otherwise indicated, all vegetative and structural erosion and sediment control practices will be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook and Virginia Regulations 4VAC50-30 Erosion and Sediment Control Regulations. ES-2'The plan approving authority must be notified one week prior to the pre -construction conference, one week prior to the commencement of land disturbing activity, and one week prior to the final inspection. ES -3. All erosion and sediment control measures are to be placed prior to or as the first step in clearing. ES -4. A copy of the approved erosion and sediment control plan shall be maintained on the site at all times. ES -5. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but limited to, off-site borrow or waste areas), the contractor shall submit a supplementary erosion control plan to the owner for review and approval by the plan approving authority. ES -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. ES -7. All disturbed areas are to drained to approved sediment control measures at all times during land disturbing activities and during site development until final stabilization is achieved. ES -8. During dewatering operations, water will be pumped into an approved filtering device. ES -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. Frederick County Note: The Public Works and Engineering Department will retain the right to add to or modify these erosion and sediment control measures during the construction process, within reason, to ensure adequate protection to the public and environment.

Pre-treatment cells should be excavated first to trap sediments before they reach the (Q -post) < Q -pre x (RV-pre/RV-post) planned filter beds. Step 3. Excavators or backhoes should work from the sides to excavate the Dry Swale area to the 0.00 <0.566 x (1145/2496) appropriate design depth and dimensions. Excavating equipment should have scoops with adequate reach so they do not have to sit inside the footprint of the Dry Swale area. 0.00 < 0.26 requirements are met. Step 4• The bottom of the Dry Swale should be ripped, roto -tilled or otherwise scarified to promote greater infiltration. STORMWA TER ANALYSIS QUALITY Steps Place an acceptable filter fabric on the underground (excavated) sides of the dry Swale with a minimum 6 inch overlap. Place the stone needed for storage layer over the filter bed. Perforate the underdrain pipe and check its slope. Add the remaining stone jacket, and then pack #57 stone Design Decision to 3 inches above the top of the underdrain, and then add 3 inches of pea gravel as a filter layer Due the small size of the proposed parking lot and location, a level 2 dry Swale shall be utilized for the BMP.

Check that outfall protection/energy dissipation measures at concentrated inflow and outflow points are stable. 6.2 Soil Infiltration Rate Testing: Not required since underdrain is being utilized. The real test of Dry Swale occurs after its first big storm. The post -storm inspection should occur on whether the desired sheetilow, shallow concentrated flows or fully concentrated flows assumed in the plan actually occur in the field. Also, inspectors should check that the Dry Swale drains 6.3 Dry Swale Geometry: completely within minimum 6 hour drawdown period.

Check inflow points for clogging, and remove any sediment. • Inspect side slopes and grass filter strips for evidence of any rill or gully erosion, and repair 6.8 Landscaping Plan as needed. • look for any bare soil or sediment sources in the contributing drainage area, and stabilize Install 3" of clean, screened topsoil prior installing turf or hydro -seeding, immediately. Ideally, inspections should be conducted in the spring of each year. Example maintenance inspection checklists for Dry Swales can be accessed in Appendix C of Chapter 9 of the Virginia Stormwater Management Handbook (2010) or at CWP website at., http://www.cwp.orq/Resource-Library/Controlling Runoff and Dischares/sm.htm (scroll to Tool& Plan Review, BMP Construction, and Maintenance Checklists) ng the remainder of the first growing season (April - October), depending on rainfall. 9.3. Routine Maintenance and Operations Once established, Dry Swales have minimal maintenance needs outride of the spring clean up, regular mowing, and pruning and management of trees and shrubs. The surface of the filter bed can become clogged with fine sediment overtime, but this can be alleviated through core aeration or deep tilling of the filter bed. Additional effort may be needed to repair check dams, stabilize inlet points, and remove deposited sediment from pre-treatment cells. ■ m C) o� k � �C:S L~rT O LAv L�/li a -1 to C 0 Q O p� � O LLJ `� -0 M J O LQ Jti �-�J Q O0) M �ti C O to W T Boo N N O N N o '0 > L- � ,;T @J ,^ VI QJ m v � N C _J ��sC� �?oazo C W V CZ� W m 0 0 'Y ZIz In C ~ zL�tiz<5 5v"'Qzazv~i W Q ti W LW ¢ CZt O u1F CcZ2 CQ Q ti L LF 041 2 Z Z C/DOOyN z O U) > ILL! �N1A W Cr O L~rT �v LAv L�/li a -1 �?oazo C W V CZ� W m 0 0 'Y ZIz In C ~ zL�tiz<5 5v"'Qzazv~i W Q ti W LW ¢ CZt O u1F CcZ2 CQ Q ti L LF 041 2 Z Z C/DOOyN z O U) > ILL!
