PROJECT DESCRIPTION THE ALBEMARLE COUNTY SERVICE AUTHORITY (ACSA) OAK FOREST PUMP STATION ABANDONMENT PROJECT CONSISTS OF THE ABANDONMENT OF THE OAK FOREST PUMP STATION AND THE INSTALLATION OF APPROX. 1,285 LF OF 8-INCH SANITARY SEWER MAIN AND 10 MANHOLES. APPROXIMATELY 0.91 ACRES OF LAND WILL BE TEMPORARILY DISTURBED IN ORDER TO COMPLETE THE SANITARY SEWER WORK. IT IS EXPECTED THAT THE PROJECT WILL START IN FALL 2018 AND BE SUBSTANTIALLY COMPLETE WITHIN 150 CALENDAR DAYS. THERE WILL BE NO CHANGES TO THE CURRENT PERVIOUS/IMPERVIOUS SURFACES AS A RESULT OF THIS PROJECT. THERE WILL BE NO CHANGES TO THE CURRENT DEVELOPED CONDITIONS OF THE SITE. EXISTING SITE CONDITIONS THE PROPOSED WORK IS PRIMARILY LOCATED BETWEEN OAK FOREST CIRLCE AND THE COSTCO WHOLESALE, SOUTHEAST OF COMMONWEALTH DRIVE. THE TERRAIN ALONG THE ALIGNMENT VARIES FROM 7 TO 25% SLOPES FOR THE MAJORITY OF THE WORK AREA. THE STEEPEST SLOPE IS LOCATED NORTHEAST OF COMMONWEALTH DRIVE BETWEEN STATIONS 13+00 TO 14+00 WHERE THE SLOPE IS AROUND 25%. ADJACENT AREAS THE ADJACENT PARCELS SURROUNDING THE SANITARY SEWER WORK ARE PRIMARILY COMMERCIALLY OWNED. THERE ARE ADDITIONAL PRIVATE LANDS OWNED BY INDIVIDUAL PROPERTY OWNERS WITHIN AND ADJACENT TO THE WORK. OFFSITE AREAS THERE WILL BE NO OFF -SITE LAND DISTURBANCE. ANY MATERIALS TAKEN OFFSITE SHALL BE TAKEN TO A PERMITTED SITE AND NOTED IN THE SWPPP. SOILS THE FOLLOWING SOIL TYPES MAY BE ENCOUNTERED WITHIN THE WORK AREA • ELIOAK LOAM (27C), 7 TO 15% SLOPES • GLENELG LOAM (34D), 15 TO 25% SLOPES • URBAN LAND (91) CRITICAL AREAS THE ONLY POTENTIAL CRITICAL AREAS IDENTIFIED WITHIN THE PROJECT AREA IS THE ALIGNMENT BETWEEN THE EXISTING OAK FOREST PUMP STATION AND COMMONWEALTH DRIVE. THIS AREA IS CONSIDERED CRITICAL BECAUSE IT IS LOCATED WITHIN THE LIMITS OF A STORMWATER RETENTION BASIN. THERE WILL BE LIMITED DISTURBANCE IN THIS AREA FOR THE INSTALLATION OF THE NEW SEWER MAIN AND ASSOCIATED MANHOLES. THE EXISTING TOPOGRAPHY WILL BE RETURNED TO PRE -CONSTRUCTION ELEVATIONS AND PERMANENT STABILIZATION WILL BE APPLIED FOLLOWING THE WORK. EROSION AND SEDIMENT CONTROL MEASURES A SERIES OF EROSION AND SEDIMENT CONTROL MEASURES SHALL BE UTILIZED TO MINIMIZE EROSION. THE EROSION AND SEDIMENT CONTROL MEASURES SHOWN ON THE PLANS FOR THIS PROJECT ARE CONSISTENT WITH THE REQUIREMENT OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, LATEST EDITION. 3.02 TEMPORARY STONE CONSTRUCTION ENTRANCE: TEMPORARY STONE CONSTRUCTION ENTRANCE WILL BE INSTALLED AT EACH VEHICULAR INGRESS AND EGRESS POINT ON THE WORK SITE TO REDUCE THE SOIL TRANSPORTED ONTO PUBLIC ROADS AND OTHER PAVED AREAS. A WASHRACK WILL BE INSTALLED PER THE DETAIL ON THE DRAWINGS WHERE VEHICLES WITH BE PROPERLY RINSED PRIOR TO INGRESS OR EGRESS OF THE WORK AREA. 3.05 SILT FENCE: SILT FENCE WILL BE INSTALLED TO DECREASE THE VELOCITY OF SHEET FLOW AND DETAIN SMALL AMOUNTS OF SEDIMENT FROM LEAVING THE CONSTRUCTION AREA. SILT FENCE SHOULD BE INSTALLED ALONG CONTOUR LINES TO THE EXTENT PRACTICABLE. SILT FENCE OUTLET PROTECTION WILL BE PLACED IN THE LOWEST PARTS WHERE THE SILT FENCE IS LOCATED TO ALLOW RUNOFF TO DISCHARGE IMMEDIATELY IN THE EVENT OF A HEAVY RAINFALL. 3.38 TREE PROTECTION: TREE PROTECTION WILL BE INSTALLED AT DESIGNATED LOCATIONS TO PROTECT IDENTIFIED TREES FROM INJURY DURING PIPELINE INSTALLATION. DUST CONTROL SHALL BE PROVIDED ACCORDINGLY TO REDUCE SURFACE AND AIR MOVEMENT OF DUST DURING LAND DISTURBANCE. PERMANENT STABILIZATION DISTURBED PORTIONS OF THE SITE WHERE CONSTRUCTION ACTIVITIES PERMANENTLY CEASE ARE TO BE STABILIZED WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED. METHODS OF PERMANENT SOIL STABILIZATION SHALL COMPLY WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, LATEST EDITION AND AS DIRECTED BY COUNTY OFFICIALS (SEE NOTE 22 OF THE ALBEMARLE COUNTY GENERAL CONSTRUCTION NOTES FOR EROSION AND SEDIMENT CONTROL PLANS). STORMWATER RUNOFF CONSIDERATIONS THERE WILL BE NO INCREASE IN PEAK RUNOFF RATES. MAINTENANCE IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CHECKED DAILY AND AFTER EACH SIGNIFICANT RAINFALL. THE FOLLOWING ITEMS SHALL BE CHECKED IN PARTICULAR: 1. INLET PROTECTION WILL BE CHECKED DAILY FOR UNDERMINING OR DETERIORATION. SEDIMENT SHALL BE REMOVED WHEN THE LEVEL OF SEDIMENT DEPOSITION REACHES HALF WAY TO THE TOP OF THE BARRIER AS REQUIRED IN ACCORDANCE WITH VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, 1992 EDITION AND THE LATEST VIRGINIA STANDARDS AND SPECIFICATIONS FOR EROSION AND SEDIMENT CONTROL. 2. SILT FENCE BARRIERS SHALL BE CHECKED REGULARLY FOR UNDERMINING OR DETERIORATION OF THE FABRIC. SEDIMENT SHALL BE REMOVED WHEN THE LEVEL OF SEDIMENT DEPOSITION REACHES HALF WAY TO THE TOP OF THE BARRIER AS REQUIRED IN ACCORDANCE WITH VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, 1992 EDITION AND THE LATEST VIRGINIA STANDARDS AND SPECIFICATIONS FOR EROSION AND SEDIMENT CONTROL. 3. PAVED WASH RACKS SHALL BE CHECKED REGULARLY FOR SEDIMENT BUILDUP WHICH WILL PREVENT DRAINAGE. IF THE PAVED WASH RACK IS CLOGGED BY SEDIMENT, IT SHALL BE CLEANED AS REQUIRED IN ACCORDANCE WITH VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, 1992 EDITION AND THE LATEST VIRGINIA STANDARDS AND SPECIFICATIONS FOR EROSION AND SEDIMENT CONTROL. 4. SEEDED AREAS SHALL BE CHECKED REGULARLY TO ENSURE THAT A UNIFORM STAND IS MAINTAINED. AREAS SHOULD BE FERTILIZED AND RE -SEEDED AS REQUIRED IN ACCORDANCE WITH VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, 1992 EDITION AND THE LATEST VIRGINIA STANDARDS AND SPECIFICATIONS FOR EROSION AND SEDIMENT CONTROL. CALCULATIONS NO CALCULATIONS ARE REQUIRED FOR THE EROSION AND SEDIMENT CONTROL PLAN. VSMP STORMWATER REQUIREMENTS THE CONSTRUCTION OF ABOVEGROUND AND UNDERGROUND LINEAR UTILITIES MAY BE EXEMPT FROM THE SWMP REQUIREMENTS IF THE PROJECT MEETS ONE OF THE FOLLOWING REQUIREMENTS: 1. THE INSTALLATION OF UNDERGROUND UTILITIES (E.G., WATERLINES, SEWER LINES, OIL AND GAS DISTRIBUTION PIPELINES) BENEATH EXISTING IMPERVIOUS COVER (E.G., ASPHALT PAVEMENT, CONCRETE PAVEMENT) THAT WILL BE RETURNED TO ITS PREDEVELOPMENT CONDITION AFTER THE COMPLETION OF CONSTRUCTION AND FINAL STABILIZATION; 2. THE INSTALLATION OF UNDERGROUND UTILITIES (E.G., WATERLINES, SEWER LINES, OIL AND GAS DISTRIBUTION PIPELINES) BENEATH EXISTING PERVIOUS COVER (E.G., FOREST/OPEN SPACE, MANAGED TURF) THAT WILL BE RETURNED TO ITS PREDEVELOPMENT CONDITION AFTER THE COMPLETION OF CONSTRUCTION AND FINAL STABILIZATION; OR 3.
