J. N. 1838 Total sheet count: 3 of 12 Erosion & Sediment Control Narrative Project Description The legal description of the project site is defined as two land parcels; TNT 14-10A0, 14-10A.3, the eastern parcel and TMP 14-I0FO and 14-1 OF3, the western parcel. The owner of the development is Innisfree, Incorporated. This project is the demolition of Laurel Village, a five unit attached residential building, tennis and basketball court and two new replacement residential buildings named Laurel and Kenmare and appurtenant site area. The total area of the AO/A3 parcel is 8.57 acres and the F0/F3 parcel is 21.65 acres based on Albemarle County GIS mapping. The total onsite area to be disturbed by the project is 3.04 acres. The total off -site area to be disturbed for the construction of utility connections is 7,000 square feet for Kenmare wastewater drainfield. The total impervious area in post developed conditions will be approximately 0.361 acres (1.2% of the two land parcels). The predevelopment impervious area is 0.646 acres (2.1% of the two land parcels). There is a net impervious area reduction of 44 percent (0.285 acres). The project is expected to start this spring and be completed within one (1) year. Storm drainage will be handled through sheet flow. The total impervious area decreases from 0.646 acres to 0.361 acres. Existing Site Conditions The site consists of an existing five (attached) wood buildings (Laurel Village), parking area, tennis court, basketball court, one storage building and one shed. No steep slopes are present in the development area. Adjacent Areas The site is bounded on all sides by Innisfree, Incorporated. On the north and east side by Tax Map 14 Parcel 10, on the south by Tax Map 14 Parcels 10, 1 0A.1, I OA2 and 10-A4, and on the west by Tax Map 14 Parcel 3. There appear to be no environmentally sensitive areas. No potential problems are anticipated for the adjacent areas during or after construction. Off -Site Areas The, project is not expected to produce soil export or soil import. Soils Desalptions The soils at this site are 25B, Dike Silt Loam. Critical Erosion Areas No critical slope areas are present within the development area. There appear to be no wetlands, watercourses, springs, etc on -site. Erosion and Sediment Control Measures Unless otherwise indicated, all erosion and sediment control practices will be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook (1992). RESPONSIBLE LAND DISTURBER WILL OBTAIN ALL PERAUTS BEFORE EXCAVATION IS TO BEGIN. Minimum Standards Installation of all erosion and sediment control measures shall conform to the 1992 Virginia Erosion and Sediment Control Handbook. Critical measures required on this project are summarized below: 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 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 and waste areas. 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 upslopr, 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. 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 How 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 the 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 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 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 every four hours and 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. Ensure compliance at the Temporary Construction Entrance. No other means of access to site shall he allowed. 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 local program authority. Disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. 17. 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: 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; and (b) All previously constructed man-made channels shall be analyzed by the use of a ten-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 ten-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 channel to a condition where a ten-year storm will not overtop the banks and a two-year storm will not cause erosion to the channel bed or banks; or (2) Improve the pipe or pipe system to a condition where the ten-year storm is contained within the appurtenances; or (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 ten-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 plan -approving authority to prevent downstream erosion. d. The applicant shall provide evidence of permission to make the improvements. c. All hydrologic analyses shall be based on the existing watershed characteristics and the ultimate development of the subject project. f. If the applicant chooses an option that includes stormwater detention he shall obtain approval from the locality 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 runoff 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. 1. 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 (1) detain the water quality volume and to release it over 48 hours; (11) detain and release over a 24-hour period the expected rainfall resulting from the one year, 24-hour storm; and (ILI) 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 § 62.1-44.15:54 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) Regulations. n. Compliance with the Water Quantity Minimum Standards set out in 9VAC25-870-66 of the Virginia Stormwater Management Program (VSMP) regulations shall be deemed to satisfy the requirements of Subdivision 19 of this subsection. Management Strategies 1. Construction should be sequenced so that grading operations can begin and end as quickly as possible. 2. The job contractor shall be responsible for the installation and maintenance of all erosion and sediment control practices. 3. Sediment trapping measures shall be installed as a first step in grading and shall be seeded and mulched immediately following installation. 4. Areas which are not to be disturbed shall be clearly marked by flags, signs, etc. Temporary Stabilization Measures 1. Temporary Construction Entrance - E&S Std. & Spec. 3.02 A Temporary Construction Entrance shall be paved with a wash rack to reduce the amount of mud transported onto paved roads. Sediment is to be directed to the sediment trap or sediment basin. Wash water must be carried away from the entrance to an approved settling area to remove sediment. All sediment shall be prevented from covering the private road and sheet flow washing downhill. See Plan. 2. Silt Fence - E&S Std. & Spec. 3.05 Silt Fence shall be installed as shown on the plans to intercept and detain sediment from disturbed areas. Utilized along perimeter of site - south, east and west sides. See Plan. 3. Temporary Seeding - E & S Std. & Spec. 3.31 Temporary vegetative cover is to be established on rough graded areas that will not be brought to final grade for a period of more than 14 days. Such areas include denuded areas, soil stockpiles, dikes, sides of sediment basins, temporary road banks, cut slopes, etc. All areas which are to be temporarily seeded shall be seeded in accordance with Minimum Standards No. 1, and shall be seeded with annual rye grass at 1-1/2 lbs/1,000 sq. ft. (including liming, mulching, fertilizing as required). Utilized along all perimeter and silt trap areas and any other aeon graveled or .non braved others areas that are disturbed 4. Tree Preservation and Protection - E&S Std. & Spec. 3.38 Silt Fence shall be installed as shown on the plans to intercept and detain sediment from disturbed areas. Utilized around specimen trees to he preserved throughoutproject area. See Plam 5. Dust Control - E&S Std. & Spec. 3.39 Dust Control shall be installed as shown on the plans to reduce airborne dust during dry conditions. Utilized in denuded areas during dry con didons to allay dust. See Plan. Permanent Stabilization Measures 1. Level Spreader - E&S Std. & Spec. 3.21 A Level Spreader shall be installed at the end of each of four (4) grass swales to dissipate concentrated flow. Level Spreader with Vegetated Lip. Utilized at ends of swales. See Plan. 2. Permanent Seeding: E&S Std. & Spec. 3.32 AR areas disturbed by construction, except areas designated for temporary seeding, will be stabilized with permanent seeding immediately following finish grading. Unless otherwise specified, permanent seeding will be done with Kentucky 31 Tall Fescue, Red Top Grass and a nurse crop of annual or winter rye (including liming, mulching and fertilizing as required) at a total rate of 150 lbs/acre according to E&S Std. and Spec. 3.32 of the 1992 Virginia Erosion and Sediment Control Handbook 3. Mulching - E&S Sid. & Spec. 3.35: Mulch shall be applied to all seeded areas in accordance with E&S Std. & Spec. 3.35. Organic mulches such as straw, wood chips (from trees cleared on site), bark chips and shredded bark may be used. Fiber mulch may be used at times other than dry summer months or late fall, and it may be used to anchor straw mulch. The use of chemical mulches and soil binders will be allowed. Rates of application shall conform to Table 3.35-A of the VESCH. Mulch shall be firmly anchored and checked often for erosion. Any erosion noted shall be quickly rectified and additional mulch applied. Maintenance Schedule All erosion and sediment control measures shall be maintained and repaired as needed until all disturbed areas have been permanently stabilized. Erosion and sediment control measures shall be inspected at least twice weekly, after each rainfall and at least once daily during prolonged rainfall. In general, all erosion and sediment control measures shall be checked and maintained by the contractor daily and after each significant rainfall. The following item will be checked in particular: Measures 1. Temporary Construction Entrance - E&S Std. & Spec. 3.02 a. The entrance shall be maintained in a condition which will prevent tracking or flow of mud onto public rights -of -way. This may require periodic top dressing with additional stone or the washing and reworking of existing stone as conditions demand and repair and/or cleanout of any structures used to trap sediment. All materials spilled, dropped, washed, or tracked from vehicles onto roadways or into storm drams must be removed immediately. The use of water trucks to remove materials dropped, washed, or tracked onto roadways will not be permitted under any circumstances. 2. Silt Fence - E&S Std. & Spec. 3.05 a. Silt fences shall be inspected immediately after each rainfall and at least daily during prolonged rainfall. Any required repairs shall be made immediately. Close attention shall be paid to the repair of damaged silt fence resulting from end runs and undercutting. b. Should the fabric on a silt fence decompose or become ineffective prior to the end of the expected usable life and the barrier still be necessary, the fabric shall be replaced promptly. c. Sediment deposits should be removed after each storm event. They must be removed when deposits reach approximately one-half the height of the barrier. d. Any sediment deposits remaining in place after the silt fence is no longer required shall be dressed to conform with the existing grade, prepared and seeded. 3. Temporary Seeding - E & S Std. & Spec. 3.31 a. Temporary vegetative cover is to be established on rough graded areas that will not be brought to final grade for a period of more than 14 days. Such areas include denuded areas, soil stockpiles, dikes, sides of sediment basins, temporary road banks, cut slopes, etc. All areas which are to be temporarily seeded shall be seeded in accordance with Minimum Standards No. 1, and shall be seeded with annual rye grass at 1-1/2 lbs./1,000 sq. ft. (including liming, mulching, fertilizing as required). If no soil test is conducted, site must be limed. 4.

Even with carefully, well -planned seeding operations, failures can occur. When it is elm that plants have not germinated on an M CD area or have died, these areas must be reseeded immediately to prevent erosion damage. However, it is extremely important to M C4 determine for what reason germination did not take place and make any corrective action necessary prior to reseeding the area. LU 04 Healthy vegetation is the most effective erosion control available. < Z 5. Mulching - E&S Std. & Spec. 3.35 5 a. All mulches and soil coverings should be inspected periodically (particularly after rainstorms) to check for erosion. Where erosion rr is observed in mulched areas, additional mulch should be applied. Nets and mats should be inspected after rainstorms for 5; UJ dislocation or failure. If washouts or breakage occur, re -install netting or matting as necessary after repairing damage to the slope UJ or ditch. Inspections should take place up until grasses are, firmly established. Where mulch is used in conjunction with LIJ ornamental plantings, inspect periodically throughout the year to determine if mulch is maintaining coverage of the soil surface; cc W LL repair as needed. U) rr Stormwater Runoff Considerations and Water Quality Post -development runoff is less than pre -development runoff. Water quality is to be handled using Grass Channels. See pre and Issue Name Date post -development runoff computations and VRRM spreadsheet for water quality phosphorous removal requirements.
