Our intent is to stage the materials there until the Corrective Measures Work Plan that we submitted on Feb. 6 is approved. Once approved, the County will issue the grading permit for placing the material on the closed landfill surface at the two locations shown in the Work Plan. At that time, the stockpiled materials will be transported to the Avon landfill. We hope to have stockpile approval by the end of the day tomorrow. if by chance, the Work Plan can be approved by the end of this week, it may not be necessary to temporarily stockpile the material. However, we still want to have the stockpile option, if the City Walk grading contractor wants to start excavating the soil- cinder area this week. We plan to stockpile the material along the east and northeast sides Of the abandoned Grand Piano building shown on the attached photos. i Were you able to get confirmation that DEQ has not concerns with the temporary stockpiling? Call me on my cell phone (804- 869- 2246), if you want to discuss this. Thanks for your help. Steve Stephen G Werner, P.G.

REFER TO THE ALBEMARLE COUNTY GENERAL NOTES (ABOVE) FOR SEEDING TYPES AND RATES. EROSION & SEDIMENT CONTROL NARRATIVE A. PROJECT DESCRIPTION THE 5TH STREET STATION SITE MAY BE USED FOR THE TEMPORARY STOCKPILING OF CINDER -SOILS AND NATURAL SOILS FROM THE CITY WALK PROJECT IN CHARLOTTESVILLE, VIRGINIA. THE CINDER -SOILS WILL BE EXCAVATED DURING GRADING FOR THE NEW WATER STREET WHICH PASSES THE CITY WALK DEVELOPMENT. IT WAS INITIALLY INTENDED TO STOCKPILE THESE MATERIALS WHILE AWAITING DEQ APPROVAL FOR THE AVON LANDFILL CORRECTIVE MEASURES PLAN (CMP), WHICH PROVIDES FOR THE PLACEMENT OF THESE MATERIALS ON THE CLOSED LANDFILL SURFACE. THE CMP WAS APPROVED BY DEQ ON FEBRUARY 21, 2013 AND A PRE - CONSTRUCTION MEETING WAS HELD ON FEBRUARY 26, 2013 FOR THE TWO APPROVED CINDER -SOIL PLACEMENT AREAS ON THE CLOSED LANDFILL. IT IS STILL DESIRED TO HAVE COUNTY APPROVAL OF THE TEMPORARY STOCKPILING E &SC PLAN, AS A CONTINGENCY iF NEEDED. THE FILL ACTIVITIES WILL BEGIN IN MARCH, 2013 AND LAST FOR APPROXIMATELY SIX MONTHS. B. EXISTING SITE CONDITIONS CONTINGENCY TEMPORARY STOCKPILE WILL BE PLACED IN THE SOUTHEAST PORTION (9.2 ACRE PARCEL) OF THE APPROXIMATELY 80 ACRE 5TH STREET STATION PROJECT. THE PORTION OF THE PROPERTY TO BE DISTURBED IS A GRAVEL /BROKEN ASPHALT PAD BETWEEN AN ABANDONED BUILDING AND AN EXISTING SOIL STOCKPILE. THE AREA IS ON A LOCAL HIGH POINT AND GENERALLY SLOPES FROM SOUTHEAST TO NORTHWEST. THE AREA HAS APPROXIMATE SLOPES OF 1% TO 3% FROM ELEVATION 428' TO 424'. CRITICAL SLOPES OF UP TO 2:1 ARE LOCATED APPROXIMATELY 50 -100' TO THE NORTHWEST, WEST AND SOUTHWEST OF THE STOCKPILES, OUTSIDE OF THE LIMITS OF DISTURBANCE. THE SiTE DRAINS INTO MOORES CREEK, WHICH RUNS ALONG THE EDGE OF THE PROPERTY APPROXIMATELY 200' TO THE NORTHWEST OF THE STOCKPILES. C. ADJACENT PROPERTY THE CONTINGENCY TEMPORARY STOCKPILE AREA IS LOCATED AT THE SOUTH END OF BENT CREEK ROAD, WHICH IS ACCESSED FROM 5TH STREET. THE 9.2 ACRE PARCEL IS SURROUNDED BY LARGER, WOODED PARCELS OF LAND WITH THE SAME OWNER. THE PROPERTY TO THE SOUTHEAST IS THE CLOSED AVON STREET LANDFILL. THE SURROUNDING PROPERTIES ARE BORDERED BY AVON STREET EXTENDED TO THE EAST /SOUTHEAST, INTERSTATE 64 TO THE SOUTH, COMMERCIAL PROPERTIES ALONG 5TH STREET (STATE ROUTE 631) TO THE WEST /NORTHWEST AND THE WILLOUGHBY NEIGHBORHOOD TO THE NORTH /NORTHEAST. MOORES CREEK WRAPS AROUND THE WEST AND NORTH PROPERTY LINES. A CONSTRUCTION ENTRANCE WILL BE INSTALLED AT THE END OF BENT CREEK ROAD. NO ADJACENT PROPERTIES WILL BE DISTURBED OR IMPACTED BY THE STOCKPILE AREAS. D. PLANNED OFF -SITE ACTIVITIES THE STOCKPILE MATERIALS WILL BE HAULED FROM THE CiTY WALK DEVELOPMENT SITE IN CHARLOTTESVILLE, VIRGINIA. THIS IS AN INDEPENDENT EROSION AND SEDIMENT CONTROL PLAN FOR THE TEMPORARY STOCKPILE AREAS ONLY. THE CONTRACTOR SHALL BE RESPONSIBLE FOR IMPLEMENTING THE SEPARATE EROSION AND SEDIMENT CONTROL PLAN FOR THE HAUL SiTE. iF ADDITIONAL OFFSITE AREAS ARE NEEDED, ANOTHER SITE PLAN AND EROSION AND SEDIMENT CONTROL PLAN WILL NEED TO BE PREPARED AND IMPLEMENTED. E. SOILS PER THE NRCS WEB SOIL SURVEY, THE STOCKPILE AREA HAS A SOIL TYPE OF UDORTHENTS, LOAMY. F. CRITICAL EROSION AREAS CRITICAL SLOPES HAVE BEEN IDENTIFIED TO THE NORTHWEST, WEST AND SOUTHWEST OF THE STOCKPILES, BUT WILL NOT BE DISTURBED DURING THE EARTHWORK. THE MEASURES SUGGESTED FOR EROSION AND SEDIMENT CONTROL WILL PREVENT ANY DEGRADATION TO THE SITE. THE CONTRACTOR SHALL ENSURE THESE AREAS ARE NOT DISTURBED OR EFFECTED DURING STOCKPILE ACTIVITIES. SHOULD THE DESIGNATED EROSION CONTROL INSPECTOR IDENTIFY AREAS WHERE ADDITIONAL MEASURES BECOME NECESSARY, THE CONTRACTOR SHALL IMMEDIATELY COMPLY WITH SUCH REQUESTS. G. 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 STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK ( VESCR). UNLESS WAIVED OR APPROVED BY THE PERMIT ISSUING AUTHORITY, THE MINIMUM STANDARDS OF VESCR SHALL APPLY. A COPY OF THE APPROVED EROSION AND SEDIMENT CONTROL PLAN IN ADDITION TO THE VESCR SHALL BE MAINTAINED ON THE SITE AT ALL TIMES. H. STRUCTURAL PRACTICES 1. TEMPORARY CONSTRUCTION ENTRANCE - 3.02 AN ASPHALT PAD WITH A WASH STATION LOCATED AT POINT OF VEHICULAR INGRESS AND EGRESS TO THE STOCKPILE AREA. THE PURPOSE IS TO PREVENT OR REDUCE THE AMOUNT OF MUD TRANSPORTED TO THE PUBLIC ROAD. 2.SILT FENCE SEDIMENT BARRIERS WILL BE INSTALLED DOWN SLOPE OF MINIMAL GRADED AREAS TO FILTER SEDIMENT LADEN RUNOFF. 3.DUST CONTROL - 3.39 DUST CONTROL MEASURES SHALL BE USED OVER THE WHOLE SITE TO REDUCE SURFACE AND AIR MOVEMENT OF DUST DURING LAND DISTURBANCE, DEMOLITION, AND CONSTRUCTION ACTIVITIES. I. VEGETATIVE PRACTICES GENERAL: A PERMANENT VEGETATIVE COVER SHALL BE ESTABLISHED ON DENUDED AREAS NOT OTHERWISE PERMANENTLY STABILIZED BY CONCRETE OR PAVEMENT. PERMANENT VEGETATION SHALL NOT BE CONSIDERED ESTABLISHED UNTIL A GROUND COVER IS ACHIEVED THAT IS UNIFORM, MATURE ENOUGH TO SURVIVE AND WILL INHIBIT EROSION. NEW VEGETATION SHALL BE MAINTAINED FOR ONE FULL YEAR AFTER PLANTING. NEW SEEDING SHALL BE SUPPLIED WITH ADEQUATE MOISTURE, ESPECIALLY LATE IN THE SEASON, AND IN ABNORMALLY HOT OR DRY WEATHER. STABILIZATION PRACTICES SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THE APPROPRIATE VESCH STD. & SPEC., ALBEMARLE COUNTY GUIDELINES AND PER THE EROSION AND SEDIMENT CONTROL PLAN. SELECTION OF THE APPROPRIATE SEED MIXTURE FOR TEMPORARY SEEDING WILL DEPEND UPON THE TIME OF YEAR IT IS APPLIED. 1. TEMPORARY SEEDING - 3.31 TEMPORARY SEEDING SHALL BE APPLIED OVER CLEARED AREAS THAT WiLL NOT BE BROUGHT TO FINAL GRADE WITHIN 14 DAYS. SEEDING IS TO BE PER THE ALBEMARLE COUNTY GUIDELINES. SEQUENCE OF INSTALLATION: WHEN STOCKPILE AREAS WILL NOT BE DISTURBED FOR 14 DAYS MAINTENANCE: REFER TO STD. & SPEC. 3.31; AREAS WHICH FAIL TO ESTABLISH VEGETATIVE COVER ADEQUATE TO PREVENT EROSION ARE TO BE RESEEDED. REMOVAL EVENT: AS NEEDED FOR FINAL GRADING. 2.PERMANENT SEEDING - 3.32 PERMANENT SEEDING SHALL BE USED ON ALL AREAS THAT WILL BE LEFT DORMANT FOR A PERIOD OF MORE THAN 1 YEAR. SEEDING IS TO BE PER THE ALBEMARLE COUNTY GUIDELINES. SEQUENCE OF INSTALLATION: WITHIN 7 DAYS OF ACHIEVING FINAL GRADE OR IF THE SITE WILL AREA WILL REMAIN UNDISTURBED FOR ONE YEAR OR LONGER. SOIL TESTING REQUIREMENTS: REFER TO STD. & SPEC. 3.32 MAINTENANCE: REFER TO STD. & SPEC. 3.32; AREAS WHICH FAIL TO ESTABLISH VEGETATIVE COVER ADEQUATE TO PREVENT EROSION ARE TO BE IMMEDIATELY RESEEDED, FOLLOWING IDENTIFICATION OF THE CAUSE OF POOR GERMINATION. J. PERMANENT STABILIZATION TEMPORARY STOCKPILED MATERIALS FROM THE CITY WALK PROJECT WILL BE TRANSPORTED TO THE CLOSED AVON LANDFILL SURFACE AND USED AS FILL IN CONJUNCTION WITH LANDSCAPING FOR THE NEW BENT CREEK PARKWAY, WHICH WILL CONNECT AVON STREET EXTENDED WITH THE 5TH STREET STATION DEVELOPMENT. ALL DISTURBED AREAS SHALL BE STABILIZED WITH PERMANENT SEEDING OR HARDSCAPE FOLLOWING THE FINAL DISTURBANCE. K. CONSTRUCTION SCHEDULE 1.
