IN APPLYING THESE STORMWATER RUNOFF CRITERIA, INDIVIDUAL LOTS OR PARCELS IN A RESIDENTIAL, COMMERCIAL OR INDUSTRIAL DEVELOPMENT SHALL NOT BE CONSIDERED TO BE SEPARATE DEVELOPMENT PROJECTS. INSTEAD THE DEVELOPMENT, AS A WHOLE, SHALL BE CONSIDERED TO BE A SINGLE DEVELOPMENT PROJECT. HYDROLOGIC PARAMETERS THAT REFLECT THE ULTIMATE DEVELOPMENT CONDITION SHALL BE USED IN ALL ENGINEERING CALCULATIONS. k. ALL MEASURES USED TO PROTECT PROPERTIES AND WATERWAYS SHALL BE EMPLOYED IN A MANNER WHICH MINIMIZES IMPACTS ON THE PHYSICAL, CHEMICAL AND BIOLOGICAL INTEGRITY OF RIVERS, STREAMS AND OTHER WATERS OF THE STATE. ACTION: IT IS THE OPINION OF THE ENGINEER THAT THE EXISTING STORM SEWER IS ADEQUATE TO CONVEY STORMWATER FOR THIS SITE. I. PROJECT DESCRIPTION: THE SUBJECT SITE IS LOCATED ALONG US ROUTE 29 SEMINOLE TRAIL ROAD AND ASHWOOD BOULEVARD THE TOTAL DISTURBED AREA FOR THE WORK PROPOSED WITH THIS PLAN IS 18.78 ACRES. THE PURPOSE OF THIS PROJECT IS TO CONSTRUCT FOUR (4) APARTMENT BUILDINGS AND SIX (6) STRIPS OF TOWNHOMES, AS WELL AS AMENITY AREAS AND ASSOCIATE PARKING. TO SERVICE THE PROPOSED DEVELOPMENT THIS PLAN WILL ALSO INCLUDE THE INSTALLATION OF SANITARY SEWER, WATER LINES, AND STORM INFRASTRUCTURE THAT WILL SERVE THE PROPOSED PARKING AREAS. THERE WILL ALSO BE TWO (2) UNDERGROUND DETENTION SYSTEMS WITH AN ISOLATOR ROW PRETREATMENT STRUCTURE CONSTRUCTED WITH THIS PLAN. THE TOTAL PROJECT IS ANTICIPATED TO TAKE EIGHTEEN (18) MONTHS TO COMPLETE. II. EXISTING SITE CONDITIONS: THE EXISTING SITE CONSISTS OF ABOUT 4.04 ACRES OF IMPERVIOUS AREA WITH SEVERAL TRAILERS AND GRAVEL LOTS SURROUNDED BY DEVELOPED GRASSED AREA. THE REMAINDER OF THE SITE CONSIST OF MOSTLY WOODED AREAS. EXISTING GRADES ON SITE ARE MOSTLY BETWEEN 0 AND 50 % WITH SEVERAL AREAS OF PRESERVED STEEP SLOPES AS INDICATED ON THE PLANS. THE TWO PROPOSED PARCELS WITHIN THIS PLAN DO NOT CONTAIN AREAS OF THE 100-YEAR FLOODPLAIN, AND NO WETLANDS OR STREAM CORRIDORS ARE IDENTIFIED. III. ADJACENT PROPERTY: THE SITE IS BORDERED TO THE NORTH BY SEMINOLE TRAIL, ROUTE 29 TO THE EAST BY SINGLE FAMILY RESIDENTIAL PARCELS, TO THE SOUTH BY THE FOREST LAKES RESIDENTIAL DEVELOPMENT, AND TO THE WEST BY ASHWOOD BOULEVARD. IV_ OFFSITE AREAS: THE PROPOSED PROJECT HAS BEEN DESIGNED TO MINIMIZE THE IMPORT AND/OR EXPORT OF DIRT FOR THE SITE. HOWEVER, IT IS ANTICIPATED THAT THERE WILL BE EXCESS FILL NEEDED TO BE TRANSPORTED ON SITE DURING CONSTRUCTION.THE CONTRACTOR IS RESPONSIBLE FOR COORDINATING ANY DISTURBANCE OFFSITE AND FOR ANY REQUIRED PLANS AND PERMITS THAT MAY BE REQUIRED. V. SOILS: A STUDY WILL BE PREPARED AT A FUTURE DATE. PER THE USGS WEB SOIL SURVEY, THE SOILS OF THE SUBJECT SITE ARE ENTIRELY HSG B. VI. CRITICALAREAS: THERE ARE SEVERAL EXISTING CRITICAL AREAS ON THE SITE INCLUDING AREAS OF PRESERVED SLOPES. APPROPRIATE MEASURES HAVE BEEN BUT INTO PLACE TO MINIMIZE THE IMPACT TO ALL CRITICAL AREAS THAT ARE IN CLOSE PROXIMITY TO THE PROPOSED PROJECT AREA ASSOCIATED WITH THIS PLAN. VII. EROSION AND SEDIMENT CONTROL MEASURES: UNLESS OTHERWISE NOTED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO MINIMUM STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK (VESCH). THE MINIMUM STANDARDS OF VESCH SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED OR APPROVED BY A VARIANCE. SPECIFIC EROSION AND SEDIMENT CONTROL MEASURES UTILIZED IN THIS PROJECT INCLUDE THE FOLLOWING: 1.
