PROJECT DESCRIPTION THE PURPOSE OF THIS PROJECT IS TO INSTALL A ONE MILLION GALLON FLOW EQUALIZATION TANK FOR THE LICKING HOLE CREEK PUMPING STATION (CROZET PS #4) IN CROZET, VIRGINIA. THE CONSTRUCTION WILL INCLUDE NEW SEWER INSTALLATION, VAULTS, MANHOLES, AND A GRAVEL ACCESS ROAD. DURING STORM EVENTS THE TANK WILL PROVIDE STORAGE TO PREVENT DOWNSTREAM OVERFLOWS OF COMBINED SEWAGE. THE COUNTY OF ALBEMARLE IDENTIFIED CROZET AS A GROWTH AREA AND ARE PROACTIVELY INCREASING SEWAGE CAPACITIES TO PREPARE. A TOTAL OF APPROXIMATELY 1.26 ACRES WILL BE DISTURBED FOR THE REGULATOR INSTALLATION. #�369YI.[�9H�R�]CI�7YIG7.6� THE TANK SITE LIES ADJACENT TO THE EXISTING PUMPING STATION CROZET PS #4 AND WILL BE ACCESSIBLE VIA A NEW GRAVEL ACCESS ROAD, THE SURROUNDING VEGETATION CONSISTS OF FORESTED WOODLANDS WITH RIPARIAN AREAS.

THE RIVANNA WATER AND SEWER AUTHORITY (RWSA) OWNS THE SITE. 3. ADJACENT AREAS THE TANK PROJECT SITE IS SURROUNDED BY THE EXISTING ACCESS ROAD AND DENSE MOUNTAINOUS FOREST LAND. ADJACENT VEGETATED AREAS WILL NOT BE DISTURBED DURING CONSTRUCTION. 4. OFF -SITE AREAS THERE ARE NO OFF -SITE (BALANCED OR BORROWED) AREAS ASSOCIATED WITH THIS PROJECT. ALL DEMOLITION DEBRIS AND OTHER SPOILS WILL BE HAULED TO A LICENSED LANDFILL. 5. SOILS THE NATURAL RESOURCES CONSERVATION SERVICE (NRCS) DATA IDENTIFIES THE SOILS ON -SITE AS HAYESVILLE CLAY AND LOAM, RIVERVIEW LOAM, AND RIVERVIEW-CHEWACLA COMPLEX WITH VARYING DEGREES OF EROSION AND PERCENT SLOPES. THE NRCS DATA DOES NOT ATTRIBUTE AN ERODIBILITY (K) VALUE TO THESE SOILS. ANY POTENTIAL EROSION RESULTING FROM THE CONSTRUCTION WILL BE CORRECTED BEFORE DEPOSITION INTO A WATERWAY. 6. CRITICAL AREAS THERE ARE NO CRITICAL AREAS ASSOCIATED WITH THIS SITE. THE LAYDOWN AND CONSTRUCTION AREAS WILL RECEIVE ALL THE APPROPRIATE SEDIMENT AND EROSION CONTROL MEASURES TO PREVENT THE DISCHARGE OF SILT AND OTHER FORMS OF WATER POLLUTION OFF -SITE. 7. EROSION AND SEDIMENT CONTROL MEASURES UNLESS OTHERWISE NOTED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CONSTRUCTED AND MAINTAINED IN ACCORDANCE WITH THE STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK (LATEST EDITION). 8.

AND SPEC. 3.20 ROCK CHECK DAMS SHALL BE PROVIDED WHERE INDICATED ON THE PLANS TO REDUCE THE VELOCITY OF CONCENTRATED STORMWATER FLOWS. F. DEWATERING STRUCTURE: STD. AND SPEC. 3.26. DEWATERING STRUCTURES SHALL DISCHARGE IN A MANNER WHICH WILL NOT ADVERSELY AFFECT FLOWING STREAMS, DRAINAGE SYSTEMS OR OFF -SITE PROPERTY. G. TURBIDITY CURTAIN: STD AND SPEC 3.27. TURBIDITY CURTAINS SHALL BE INSTALLED WHERE DESIGNATED ON THE EROSION AND SEDIMENT CONTROL PLANS TO PROVIDE SEDIMENTATION PROTECTION FOR A WATERCOURSE FROM UP -SLOPE LAND DISTURBANCE OR FROM DREDGING OR FILLING WITHIN THE WATERCOURSE. H. DUST CONTROL: STD. AND SPEC. 3.39. DUST CONTROL MEASURES TO PREVENT SURFACE AND AIR MOVEMENT OF DUST FROM EXPOSED SOIL SURFACES AND REDUCE THE AIRBORNE SUBSTANCES WHICH MAY PRESENT HEALTH HAZARDS, TRAFFIC SAFETY PROBLEMS OR HARM ANIMAL OR PLANT LIFE WILL BE EXERCISED THROUGHOUT THE PROJECT DURATION. 1. WHERE CONSISTENT WITH SAFETY AND SPACE CONSIDERATIONS, EXCAVATED MATERIAL IS TO BE PLACED ON THE UPHILL SIDE OF EXCAVATIONS. 9. VEGETATION PRACTICES TEMPORARY SEEDING STD. AND SPEC. 3.31. ALL AREAS ROUGH -GRADED DURING THE INITIAL PHASES OF CONSTRUCTION SHALL BE SEEDED WITH FAST GERMINATING, TEMPORARY VEGETATION WITHIN 7 DAYS FOLLOWING GRADING WHEN EXPOSED SOILS ARE NOT TO BE PERMANENTLY STABIUZED WITHIN 30 DAYS. SEEDING MIX OF GERMAN MILLET (SETARIA ITALICA) AT A RATE OF 50 LBS/ACRE WILL BE APPLIED AS TEMPORARY SEEDING FROM MAY 1 THROUGH AUGUST 31.
