The area will hold 40- 44,000 yards of soil (approximately 110,000 yds. will be needed for anticipated site). Soil will be imported from several local project sites, including Oakhurst, Meadowbrook Parkway and/or Fontana. Only good soil will be imported. EXISTING SITE CONDITIONS The site consist of trees and vines on sloped terrain. Many of the trees in the area have sprouted from damaged roots removed in 2005. Many of the trees are covered with vines and are dying as evidenced by the dead limbs/branches and rot, as noted by a certified arborist. ADJACENT AREAS Most of the adjacent area is made up of the same trees and vines and includes some healthy trees. These areas will not be disturbed. OFF-SITE AREA Fill material is being imported from sites including Oakhurst, Fontana and the Meadowbrook Parkway, and will only be brought to the site from other sites where adequate E&S measures have been implemented and meet local, state and federal requirements known. SOILS According to the USDA SCS Soil Mapping, the project site lies on soil types: Elioak Loam-27B and Hazel Loam-39D. CRITICAL AREAS The limits of disturbance area do not include any area deemed"critical slope"according to the Albemarle County GIS. EROSION AND SEDIMENT CONTROL MEASURES The area will include 450 LF of well-defined diversion ditch or dike(seeded and strawed)to the west from 5th street to trap, 600 feet of silt fence to the east/north east from the north side of the demoed house to the trap.A silt trap is located where the silt fence and diversion ditch/dike meet to the north. The silt trap is designed for a 2.5 acre area. The rock weir is to be constructed using concrete foundation of demoed house broken into Class 1 size pieces to be used along with#3 VDOT stone for filter with fabric underlayment. The entrance to the area includes over 70 feet of existing pavement and an additional 30 feet of paving with#3 stone and fabric added to one side for wide truck traffic. PERMANENT STABILIZATION See General Notes for Erosion and Sediment Control Plans STORMWATER RUNOFF CONSIDERATIONS Contractor to monitor stormwater channels and any potential for future flooding and potential downstream channel degradation. CALCULATIONS -Per sketch Note: • Limts of disturabance-backside of erosion control measures • Stockpile slope no greater than 2:1 Sequence of construction • Contractor/owner shall provide and post bond estimate to County of Albemarle and schedule preconstruction meeting. • Contractor shall install all perimeter controls, construction entrance, silt fence, rliversinn ditch and silt trap. Trees within limits of construction that are to remain shall have proper tree protection as part of E&S measures. • With perimeter controls installed, stabilized, and functioning, contractor can begin to stockpile. Contractor shall stabilize per temporary seeding requirements. • Once the site is deemed stabilized by the county of Albemarle, the temporary erosion and sediment controls devices can be removed and disturbed areas permanently stabilized. General Notes for Erosion and Sediment Control Plans 1.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. 2.All erosion and sediment control measures will be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook and Virginia Regulations VR 625-02-00 Erosion and Sediment Control Regulations. 3.All erosion and sediment control measures are to be placed prior to or as the first step in clearing. 4. A copy of the approved erosion and sediment control plan shall be maintained on the site at all times. 5. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but not 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. 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. 7.All disturbed areas are to drain to approved sediment control measures at all times during land disturbing activities and during site development until final stabilization is achieved. 8. During dewatering operations,water will be pumped into an approved filtering device. 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. 10.All fill material to be taken from an approved,designated borrow area. 11.All waste materials shall be taken to an approved waste area. Earth fill shall be inert materials only, free of roots, stumps,wood, rubbish, and other debris. 12. Borrow or waste areas are to be reclaimed within 7 days of completion per Zoning Ordinance section 5.1.28. 13.All inert materials shall be transported in compliance with section 13-301 of the Code of Albemarle. 14. Borrow, fill or waste activity involving industrial-type power equipment shall be limited to the hours of 7:00am to 9:00pm. 15. Borrow, fill or waste activity shall be conducted in a safe manner than maintains lateral support,or order to minimize any hazard to persons, physical damage to adjacent land and improvements, and damage to any public street because o slides, sinking,or collapse. 16.The developer shall reserve the right to install, maintain, remove or convert to permanent stormwater management facilities where applicable all erosion control measures required by this plan regardless of the sale of any lot, unit, building or other portion of the property. 17.Temporary stabilization shall be temporary seeding and mulching. Seeding is to be at 75 lbs/acre, and in the months of September to February to consist a 50/50 mix of Annual Ryegrass and Cereal Winter Rye, or in March and April to consist of Annual Rye,or May through August to consist of German Millet. Straw mulch is to be applied at 80Ibs/100sf.Alternatives are subject to approved by the County erosion control inspector. 18.

Fertilizer shall be applied at 1000Ibs/acre and consist of a 10-20-10 nutrient mix. Permanent seeding shall be applied at 180Ibs/acre and consist of 95%Kentucky 31 or Tall Fescue and 0-5%Perennial Ryegrass or Kentucky Bluegrass. Straw mulch is to be applied at 801bs/100sf.Alternatives are subject to approved by the County erosion control inspector. 19. Maintenance:All measures are to be inspected weekly and after each rainfall.Any damage or clogging to structural measures is to be repair immediately.Silt traps are to be cleaned when 50%of the wet storage volume is filled with sediment.All seeded areas are to be reseeded when necessary to achieve a good stand of grass.Silt fence and diversion dykes which are collecting sediment to half their height must be cleaned and repaired immediately. 20.All temporary erosion and sediment control measures are to be removed within 30 days of final site stabilization, when measures are no longer needed, subject to approval by the County erosion control inspector. 21.This plan shall be void if the owner does not obtain a permit within 1 year of the date of approval. (Water Protection Ordinance section 17-204G.) 22. Permanent vegetation shall be installed on all denuded areas within nine (9) months after the date the land disturbing activity commenced.

Dear Mac: There are several trees that should not be taken down. The majority of these trees are located on the south end of the designated area close to 5th Street and in areas parallel to 5th Street, approximately 400 ft. to the west. For most of the site, it was my observation that the trees partially covered in vines are dying. This was evident by the number of dead limbs/branches visible. Much damage has already occurred to trees in the vined areas. This damage is also evidenced by rot located at the base of the trees. These trees are not salvageable and, for safety reasons, should be removed as these areas are approached. It should be noted that the majority of the trees in this area were cut down in 2005 and many of the trees in this area have sprouted from the roots systems damaged during the first removal. These root systems are usually deficient and should be removed for safety reasons. Care should be taken when removing these trees. This includes the sycamore trees , -tip-7 .A:h/ Roger L.
