AutoCAD SHX Text: EROSION & SEDIMENT CONTROL NARRATIVE: EXISTING CONDITIONS THE SITE IS LOCATED AT THE EAST POTOMAC MAINTENANCE YARD AT 500 BUCKEYE DRIVE, SW, WASHINGTON DC 20024. THE SW, WASHINGTON DC 20024. THE SW, WASHINGTON DC 20024. THE SITE CURRENTLY CONTAINS A FUEL STATION CONSISTING OF A 5,000 GALLON UNDERGROUND FUEL STORAGE TANK FOR GASOLINE AND A 2,000 GALLON UNDERGROUND FUEL STORAGE TANK FOR DIESEL FUEL ALONG WITH THE ASSOCIATED FUEL DISPENSERS, FUEL INVENTORY CONTROL UNIT, CANOPY, AND FUEL ATTENDANT BUILDING. THE FUEL STATION IS CONSTRUCTED IN AN AREA OF CONCRETE PAVEMENT AND IS BOUNDED BY CURB AND GUTTER ON THE NORTH AND SOUTH SIDES AND TRENCH DRAINS ON THE EAST AND WEST SIDES TO WHICH THE CONCRETE PAVEMENT DRAINS. THE TRENCH DRAINS CONVEY STORMWATER RUNOFF FROM THE CONCRETE PAVEMENT AT THE FUEL STATION TO AN EXISTING SAND & OIL INTERCEPTOR AT THE SOUTHEAST SIDE OF THE FUEL STATION. A SMALL FUEL ATTENDANT BUILDING IS LOCATED IN A CONCRETE ISLAND SURROUNDED BY CURB AND GUTTER LOCATED SOUTH OF THE FUEL STATION. AN APPROXIMATE 1,400 SF MAINTENANCE BUILDING IS ALSO PRESENT AT THE SITE AND IS LOCATED SOUTHEAST OF THE FUEL STATION. ASPHALT PAVEMENT SURROUNDS THE MAINTENANCE BUILDING. GRADES SLOPE GRADUALLY AWAY FROM THE BUILDING IN THE NORTHEAST AND NORTHWEST DIRECTIONS TO TWO EXISTING CURB INLETS AT THE SOUTHEAST AND SOUTHWEST CORNER OF THE CONCRETE ISLAND ON WHICH THE FUEL ATTENDANT BUILDING RESIDES. PROJECT DESCRIPTION SITE WORK ASSOCIATED WITH THIS PROJECT INCLUDES REPLACEMENT OF THE EXISTING UNDERGROUND FUEL STORAGE TANKS WITH TWO ABOVE GROUND FUEL STORAGE TANKS ON A CONCRETE EQUIPMENT PAD INCLUDING ALL ASSOCIATED DEMOLITION, EXCAVATION, PAVEMENT REMOVAL AND REPLACEMENT, AND UTILITY WORK. THE EXISTING CANOPY COVERING THE EXISTING FUEL STATION WILL ALSO BE REMOVED & REPLACED. THE EXISTING CANOPY ROOF DRAINS WILL BE TEMPORARILY CAPPED BELOW GRADE UNTIL RECONNECTION OF THE NEW CANOPY ROOF DRAINS. THE PROJECT ALSO INCLUDES RENOVATION OF THE NORTHWEST SERVICE BAY OF THE EXISTING MAINTENANCE BUILDING TO CONVERT THE NORTHWEST BAY TO SUPPORT VEHICLE AND EQUIPMENT WASHING. SITE WORK ASSOCIATED WITH THE MAINTENANCE BUILDING RENOVATION INCLUDES CONSTRUCTION OF A NEW OIL-WATER SEPARATOR OUTSIDE THE MAINTENANCE BUILDING, ASSOCIATED UTILITY WORK, AND PAVEMENT RESTORATION. A NEW OUTDOOR WASH STATION (HOSE BIB) WILL ALSO BE PROVIDED ON THE NORTHWEST SIDE OF THE MAINTENANCE BUILDING. SITE WORK ASSOCIATED WITH THE NEW OUTDOOR WASH STATION INCLUDES CONSTRUCTION OF A NEW TRENCH DRAIN AT THE NORTH CORNER OF THE MAINTENANCE BUILDING TO INTERCEPT FLOW FROM THE OUTDOOR WASH STATION. THE NEW TRENCH DRAIN WILL DISCHARGE TO A NEW DRAIN BASIN. THE NEW DRAIN BASIN WILL HAVE AN OUTLET PIPE TO THE STORM SEWER AND AN OUTLET PIPE TO THE SANITARY SEWER AS SHOWN ON THE UTILITY PLAN. BOTH OUTLET PIPES WILL BE CONSTRUCTED WITH A NEW GATE VALVE IMMEDIATELY AFTER THE CONNECTION TO THE DRAIN BASIN WHICH WILL ALLOW CONTROL OF THE DISCHARGE TO THE APPROPRIATE UTILITY SYSTEM AS FOLLOWS: WHEN THE OUTDOOR WASH STATION IS NOT NOT IN USE, THE GATE VALVE IN THE STORM SEWER WILL BE SET IN THE OPEN POSITION & THE GATE VALVE IN THE SANITARY SEWER WILL BE SET IN THE CLOSED POSITION TO DIVERT RAINFALL TO THE STORM SEWER SYSTEM & PREVENT IT FROM ENTERING THE SANITARY SEWER/OIL-WATER SEPARATOR. WHEN THE OUTDOOR WASH STATION IS IN USE, THE GATE VALVE IN THE STORM SEWER WILL BE SET IN THE CLOSED POSITION & THE GATE VALVE IN THE SANITARY SEWER WILL BE SET IN THE OPEN POSITION TO DIVERT FLOW FROM VEHICLE WASHING OPERATIONS TO THE SANITARY SEWER/OIL-WATER SEPARATOR. SOIL TYPE SOILS TYPES IN THE PROJECT AREA, AS DESCRIBED BY SOIL SURVEY INFORMATION AVAILABLE AT USDA NATURAL SOILS TYPES IN THE PROJECT AREA, AS DESCRIBED BY SOIL SURVEY INFORMATION AVAILABLE AT USDA NATURAL RESOURCES CONSERVATION SERVICE (NCRS) ARE AS SHOWN ON THE SOILS INFORMATION MAP AND SOILS DATA TABLE PROVIDED ON SHEET C-301.
