THE DISTURBANCE AREA ASSOCIATED WITH THIS PROJECT IS t0.40 AC (17,625 SF). IT IS ANTICIPATED THAT THE WORK WILL START IN AUGUST AND LAST TWO MONTHS. EXISTING SITE CONDITIONS: THE SITE CONSISTS OF AN EXISTING ELEMENTARY SCHOOL WITH ASSOCIATED PARKING AND AMENITIES. THE SLOPES WITHIN THE PROJECT AREA RANGE FROM 2 TO 7 PERCENT. ADJACENT AREAS: THE PROPOSED PROJECT IS ADJACENT TO OFFICE BUILDINGS ON THE NORTH SIDE, AVON STREET EXTENDED ON THE EAST, RESIDENTIAL HOUSING SOUTH, AND VACANT LAND ON THE WEST. OFF -SITE AREAS: IT IS NOT ANTICIPATED THAT ANY OFF -SITE AREAS WILL BE DISTURBED DURING CONSTRUCTION. UNSUITABLE MATERIALS RESULTING FROM THE PROPOSED WORK SHALL BE HAULED FROM THE SITE AND DISPOSED OF AT AN APPROVED DISPOSAL SITE PERMITTED SEPARATELY FROM THIS PROJECT. SOILS: SEE THE USDA SOILS DELINEATION MAP ON THIS SHEET. CRITICAL AREAS: THIS PROJECT SITE DOES NOT HAVE ANY CRITICAL AREAS. EROSION & SEDIMENT CONTROL MEASURES: REFER TO THIS SHEET FOR A LIST OF ALL PROPOSED EROSION AND SEDIMENT CONTROL MEASURES TO BE USED ON SITE. PERMANENT STABILIZATION: THE SITE WILL BE STABILIZED THROUGH THE USE OF PERMANENT SEEDING. SEEDING INFORMATION, DATES AND AMENDMENTS ARE INCLUDED ON THE PLANS. SOIL TESTING SHALL BE COMPLETED THE CONTRACTOR TO DETERMINE THE SUITABILITY OF EXISTING SOILS AND THE NEED FOR ANY SOIL AMENDMENTS TO ENSURE THAT PERMANENT SEEDING WILL GROW EFFECTIVELY. STORM WATER RUNOFF CONSIDERATIONS: THE PROPOSED WORK WILL NOT SIGNIFICANTLY ALTER THE EXISTING DRAINAGE PATTERNS ON SITE. STORMWATER RUNOFF DURING CONSTRUCTION WILL BE DIRECTED THROUGH APPROPRIATE EROSION AND SEDIMENT CONTROLS TO CLEAN WATER BEFORE DISCHARGING TO AN ADEQUATE OUTFALL PROTECTED FROM EROSION AND SEDIMENT AS SHOWN ON THE PLANS. MAINTENANCE: ALL E&S MEASURES SHALL BE INSPECTED REGULARLY AS REQUIRED BY STATE STANDARDS AND MAINTAINED IN GOOD WORKING ORDER. REQUIRED REPAIRS SHALL BE MADE IMMEDIATELY.

MEASURES SHOULD BE CLEANED AND REPAIRED ACCORDING TO THE FOLLOWING SCHEDULE AND THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. THE FOLLOWING WILL BE CHECKED IN PARTICULAR: 1. THE CONSTRUCTION ENTRANCES AND CONSTRUCTION ROAD STABILIZATION AREAS SHALL BE MAINTAINED IN A CONDITION WHICH WILL PREVENT TRACKING OR FLOW OF MUD ONTO PUBLIC RIGHTS -OF -WAY THROUGH PERIODIC TOP DRESSING WITH ADDITIONAL STONE AND/OR WASHING AND REWORKING OF EXISTING STONE. 2. SEDIMENT DEPOSITS SHALL BE REMOVED FROM SILT FENCE AFTER EACH RAINFALL. UNDER NO CIRCUMSTANCES SHALL DEPOSITS BE ALLOWED TO ACCUMULATE ABOVE HALF THE HEIGHT OF THE FENCE. DAMAGED OR UNDERCUT SILT FENCE SHALL BE REPAIRED IMMEDIATELY. SHOULD SILT FENCE BECOME INEFFECTIVE OR REACH THE END OF THE EXPECTED USEABLE LIFE, FABRIC SHALL BE REPLACED IMMEDIATELY. UPON SILT FENCE REMOVAL, DRESS ANY SEDIMENT DEPOSITS TO CONFORM WITH EXISTING GRADE AND SEED. 3. INLET PROTECTION SHALL BE CHECKED REGULARLY FOR SEDIMENT. IF EXCESSIVE SEDIMENT IS PRESENT, OR IF EXCESSIVE PONDING OCCURS AFTER RAINFALL, THE STONE SHALL BE PULLED AWAY AND CLEANED OR REPLACED. 4.

FERTILIZER & LIME Apply 10-20-10 Fertilizer at a rate of 500lbs/acre (or 12 Its, / 1,000 W. ft.) Apply Pulverized Agricultural Limestone at a rate of 2 tons/acre (or 901bs. / 1.000 sq. ft.) NOTE: -A soil test is necessary to determine the actual amount of lime required to adjust the soil pH of site. - Incorporate the lime and fertilizer into the top 46 inches of the soil by disking or by other means. - When applying Slowly Available Nitrogen, use rates available in Erosion & Sediment Control Technical Bulletin q4 2003 Nutrient Management for Development Sites at http://,.dN.virginia.gov/Programs/water/Stormwater Manageme l/Publications.aspx SEEDING SCHEDULES Uj ta Z tL j Z Z Uj W z J U) J Q w `} / 0 J < 0 z w z z w o J z> U ``J z z 0- 0-o W wow >>W 0 z 2 w LU M Cf) z Q 0 ZD Q o G z O O Ir TH Op� DANIEL C.

RUNOFF FROM THE ADDED MODULAR CLASSROOM BUILDING ROOF WILL BE COLLECTED AND ROUTED TO A LEVEL SPREADER TO RETURN TO SHEET FLOW BEFORE LEAVING THE PROJECT LIMITS. QUALITY COMPLIANCE THE NUTRIENT REMOVAL REQUIREMENTS WERE CALCULATED WITH THE VRRM SPREADSHEET, UTILIZING THE LIMITS OF DISTURBANCE AREA AS THE PROJECT LIMITS. THIS PROJECT MEETS STORMWATER QUALITY REQUIREMENTS SET FORTH BY 9VAC25-870-63 THROUGH THE PURCHASE OF NUTRIENT CREDITS IN THE EQUIVALENT OF 0.41 LBS/YR PHOSPHORUS. SEE VRRM TABULATIONS ON THIS SHEET. QUANTITY COMPLIANCE CHANNEL AND FLOOD PROTECTION REQUIREMENTS ARE BOTH ADDRESSED BY RETURNING RUNOFF FROM WITHIN THE PROJECT LIMITS TO SHEET FLOW VIAA LEVEL SPREADER (9VAC25-870-66D). THE VOLUME OF SHEET FLOW IS NOT SIGNIFICANTLY ALTERED IN A WAY THAT WOULD ERODE OR FLOOD DOWN GRADIENT PROPERTIES.
