THE PROJECT ALSO INVOLVES THE MASS GRADING OF A FUTURE APARTMENT SITE THAT LIES IN THE CENTER THIS PROJECT, ALSO A PART OF THE OVERALL NORTH POINTE PROJECT, AND THE INSTALLATION OF TWO LARGE SWMBMP BASINS AND TWO BIO-RETENTION BASINS. THE FOUR BMPS HAVE BEEN DESIGNED TO COLLECTIVELY ADDRESS THE WATER QUALITY AND QUANTITY ASSOCIATED WITH THIS RESIDENTIAL DEVELOPMENT, THE FUTURE APARTMENT SITE, AND A PORTION OF A FUTURE RESIDENTIAL DEVELOPMENT EAST OF THIS PROJECT. WATER AND SANITARY SEWER WILL BE EXTENDED TO SERVICE THE FUTURE NORTH POINTE DEVELOPMENTS. THE DISTURBED AREA ASSOCIATED WITH THIS PROJECT IS APPROXIMATELY 50 ACRES. EXISTING SITE CONDITIONS THE EXISTING SITE IS MOSTLY FORESTED. THE MAJORITY OF THE SITE SLOPES NORTHWEST TO FLAT BRANCH. THE SITE CONTAINS WATERS OF THE U.S. THAT SHALL REMAIN UNDISTURBED EXCEPT FOR THE PERMITTED AREAS TO BE IMPACTED. GRAVITY SANITARY SEWER AND A 12" WATERLINE ARE AVAILABLE FOR CONNECTION ON THE MIDDLE ENTRANCE ROAD AS PART OF THE NORTHPOINTE MIDDLEENIR4NCEANDROUTE 297MPROVEMENTSPROJECT. EACHWILLBE EXTENDED TO SERVICE THIS PROJECT AND FUTURE NORTH POINTE DEVELOPMENTS. ADJACENT AREAS THE SITE IS BORDERED BY THE NORTH POINTE MIDDLE ENTRANCE AND ROUTE 19 IMPROVEMENTS PROJECT AND FLAT BRANCH TO THE WEST, PRITCHETT DRIVE (VA 785) TO THE SOUTH, AND A FUTURE NORTH POINTE RESIDENTIAL DEVELOPMENT TO THE EAST. OFFSITE AREAS THERE IS NO OFFSITE WORK PROPOSED WITH THIS PROJECT. SOILS THE SITE IS CHARACTERIZED BY SANDY, LEAN CLAY (CL) AND SILTY, LEAN SAND (SM). CRITICAL AREAS THE CRITICAL AREAS ASSOCIATED WITH THIS PROJECT INCLUDE FLAT BRANCH AT THE PROPOSED CROSSCREEK DRIVE ROAD CROSSING. DISTURBED AREA SHOULD BE LIMITED TO WHAT IS SHOWN ON THE PLANS. OTHER SEN SIfIVE AREAS INCLUDE WETLANDS AND WATERS OF THE U.S., CONTRACTOR MUST CONTROL EROSION AND SEDIMENTATION FROM LAND DISTURBING ACTIVITIES AND PREVENT THEM FR40M ENTERING WATERWAYS. THIS SITE IS SET UP TO DRAIN TO FIVE SEDIMENT TRAPS AND TWO SEDIMENT BASINS WHICH WILL BE MAINTAINED UNTIL THE SITE IS STABILIZED. THE SITE CONTAINS STEEP SLOPES THROUGHOUT THE DISTURBED AREAS. THESE DISTURBED AREAS WILL NEED TO BE SEEDED AND STABILIZATION ACHIEVED TO PREVENT EROSION FROM OCCURRING AS THE WORK PROGRESSES. THE CONTRACTOR SHOULD ALSO TAKE CARE TO KEEP CONSTRUCTION ENTRANCES IN GOOD WORKING CONDITION IN ORDER TO NOT TRACK MUD ONTO EXISTING ROADWAYS. EROSION AND SEDIMENT CONTROL MEASURES - PHASE I 1 - ALL EROSION AND SEDIMENT CONTROL MEASURES MUST BE INSTALLED, MAINTAINED AND REMOVED IN ACCORDANCE WITH THE CRITERIA AND GUIDELINES CONTAINED IN THE CURRENT EDITION OF THE VIRGINIA EROSION & SEDIMENT CONTROL HANDBOOK. 2 -PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT (UNDISTURBED) FOR LONGER THAN 14 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR 3 - WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY (VEHICULAR) TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER 4 - UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THE FOLLOWING STANDARDS IN ADDITION TO OTHER APPLICABLE CRITERIA: A - NO MORE THAN 500 LINEAR FEET OF TRENCH MAY BE OPENED AT ONE TIME. B - EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHILL SIDE OF TRENCHES. C - EFFLUENT FROM DEWATERING OPERATIONS SHALL BE FILTERED OR PASSED THROUGH AN APPROVED SEDIMENT TRAPPING DEVICE, OR BOTH, AND DISCHARGED IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING STREAMS OR OFF -SITE PROPERTY. D - RESTABILIZATION SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THESE REGULATIONS. E - APPLICABLE SAFETY REGULATIONS SHALL BE COMPLIED WITH. 5 - ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY ENVIRONMENTAL ENGINEERING IF WARRANTED BY FIELD CONDITIONS. 6 - THE TEMPORARY SEDIMENT TRAPS OR SEDIMENT BASIN SHALL NOT BE REMOVED UNTIL APPROVED BY ENVIRONMENTAL ENGINEERING. 7 - A VDOT LAND USE PERMIT IS REQUIRED FOR THIS PROJECT PRIOR TO ISSUANCE OF A LAND DISTURBANCE PERMIT. 8 - AT THE TIME OF THE PRE -CONSTRUCTION MEETING, TWO STANDARD SIGNS MUST BE INSTALLED ON EACH SIDE OF THE CONSTRUCTION ACCESS. THESE SIGNS SHOULD STATE EITHER "CONSTRUCTION ENTRANCE AHEAD" OR "TRUCKS ENTERING HIGHWAY". CONSTRUCTION SEQUENCE TO BE AS FOLLOWS: 1. THE OWNER MUST GIVE THE COUNTY INSPECTOR 48 HOURS NOTIFICATION TO SCHEDULE A PRE -CONSTRUCTION MEETING THAT WILL BE HELD AT COUNTY OFFICE BUILDING LOCATED AT 401 MCINTIRE ROAD FOR THE ISSUANCE OF A LAND DISTURBANCE PERMIT. 2. THE CERTIFIED RESPONSIBLE LAND DISTURBER (CRLD) MUST ATTEND THE PRE - CONSTRUCTION MEETING. 3.

PERMANENT STABILIZATION THE CONTRACTOR SHALL PROVIDE GRASS STABILIZATION ON ALL DENUDED AREAS PRIOR TO TURNOVER OF THE PROJECT TO THE DEVELOPER. SEED SHALL BE APPLIED AS DICTATED IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK FOUR BMPS HAVE BEEN DESIGNED TO COLLECTIVELY ADDRESS THE WATER QUANTITY ASSOCIATED WITH THIS RESIDENTIAL DEVELOPMENT, THE FUTURE APARTMENT SITE, AND A PORTION OF THE FUTURE RESIDENTIAL SECTION EAST OF THIS SECTION. THE POST DEVELOPMENT RUNOFF WILL BE CONTAINED ONSITE IN TWO RETENTION BASINS AND TWO BIO-RETENTION FILTERS THAT ARE DESIGNED TO MAINTAIN A STORM POST -DEVELOPMENT RUNOFF RATE THAT IS LESS THAN THE STORM PRE -DEVELOPMENT RUNOFF RATE FOR THE APPLICABLE SITE AREA. MS-19 IS BEING ACHIEVED WITHIN THE NATURAL CHANNELS THROUGH THE STORM BEING CONTAINED WITHIN THE CHANNEL BANKS AND NOT CAUSING THE CHANNEL BEDS TO ERODE. MAINTENANCE IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED DAILY AND AFTER EACH SIGNIFICANT RAINFALL. SITE INSPECTIONS SHALL BE CONDUCTED AS SPECIFIED IN VAR10-PART II-F. ATTENTION WILL BE GIVEN TO THE FOLLOWING ITEMS: a. SEDIMENT TRAPS WILL BE CLEANED AND MAINTAINED IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK b. THE BASIN EMBANKMENTS SHOULD BE CHECKED REGULARLY TO ENSURE THAT THEY ARE STRUCTURALLY SOUND AND HAVE NOT BEEN DAMAGED BY EROSION OR CONSTRUCTION EQUIPMENT. THE BASINS SHOULD BE CHECKED AFTER EACH RUNOFF -PRODUCING RAINFALL FOR SEDIMENT CLEANOUT. WHEN THE SEDIMENT REACHES THE CLEAN -OUT LEVEL, IT SHALL BE REMOVED AND PROPERLY DISPOSED. C. SILT FENCE SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND AT LEAST DAILY DURING PROLONGED RAINFALL. ANY REQUIRED REPAIRS SHALL BE MADE IMMEDIATELY. SEDIMENT DEPOSIT SHOULD BE REMOVED AFTER EACH STORM EVENT. ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE SILT FENCE IS NO LONGER REQUIRED SHALL BE DRESSED TO CONFORM TO THE EXISTING GRADE, PREPARED AND SEEDED. D. ALL GRAVEL OUTLETS WILL BE CHECKED REGULARLY FOR SEDIMENT BUILDUP THAT WILL PREVENT PROPER DRAINAGE. IF THE GRAVEL IS CLOGGED BY SEDIMENT, THE GRAVEL WILL BE REMOVED AND CLEANED, OR IT WILL BE REPLACED. E. DIVERSION DIKES SHALL BE INSPECTED AFTER EVERY STORM EVENT AND REPAIRS MADE TO THE DIKES, FLOW CHANNELS, OUTLET OR SEDIMENT TRAPPING FACILITY, AS NECESSARY. ONCE EVERY TWO WEEKS, WHETHER A STORM EVENT HAS OCCURRED OR NOT, THE MEASURE SHALL BE INSPECTED AND REPAIRS MADE IF NEEDED. DAMAGES CAUSED BY CONSTRUCTION TRAFFIC OR OTHER ACTIVITY MUST BE REPAIRED BEFORE THE END OF EACH WORKING DAY. DUST CONTROL THE FOLLOWING TEMPORARY DUST CONTROL MEASURES SHALL BE USED DURING CONSTRUCTION: - VEGETATIVE COVER: IN AREAS SUBJECT TO LITTLE OR NO CONSTRUCTION TRAFFIC, A VEGETATIVE STABILIZED SURFACE WILL REDUCE DUST EMISSIONS. - MULCH: NOT RECOMMENDED FOR AREAS WITHIN HEAVY TRAFFIC PATHWAYS. - IRRIGATION: SITE TO BE SPRINKLED WITH WATER UNTIL THE SURFACE IS WET. REPEAT AS NEEDED. IT OFFERS FAST PROTECTION FOR HAUL ROADS AND OTHER HEAVY TRAFFIC ROUTES. IN ADDITION TO THE TEMPORARY DUST CONTROL MEASURES, PERMANENT METHODS SHALL BE APPLIED AND THEY ARE AS FOLLOWS: - PERMANENT VEGETATION: APPLY PERMANENT SEEDING (PER STD 3.32). EROSION AND SEDIMENT CONTROL MEASURES - PHASE II 1 - ALL EROSION AND SEDIMENT CONTROL MEASURES MUST BE INSTALLED, MAINTAINED AND REMOVED IN ACCORDANCE WITH THE CRITERIA AND GUIDELINES CONTAINED IN THE CURRENT EDITION OF THE VIRGINIA EROSION & SEDIMENT CONTROL HANDBOOK. 2 - PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT (UN➢ISTURBED) FOR LONGER THAN 14 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR 3 - WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY (VEHICULAR) TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTED TO A SEDPAENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER 4 - UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THE FOLLOWING STANDARDS IN ADDITION TO OTHER APPLICABLE CRITERIA: A - NO MORE THAN 500 LINEAR FEET OF TRENCH MAY BE OPENED AT ONE TIME. B - EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHILL SIDE OF TRENCHES. C - EFFLUENT FROM DEWATERING OPERATIONS SHALL BE FILTERED OR PAS SED THROUGH AN APPROVED SEDIMENT TRAPPING DEVICE, OR BOTH, AND DISCHARGED IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING STREAMS OR OFF -SITE PROPERTY. D - RESTABILIZATION SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THESE REGULATIONS. E - APPLICABLE SAFETY REGULATIONS SHALL BE COMPLIED WITH. 5 - ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY ENVIRONMENTAL ENGINEERING IF WARRANTED BY FIELD CONDITIONS. 6 - THE TEMPORARY SEDIMENT TRAPS OR SEDIMENT BASIN SHALL NOT BE REMOVED UNTIL APPROVED BY ENVIRONMENTAL ENGINEERING. 7 - A VDOT LAND USE PERMIT IS REQUIRED FOR THIS PROJECT PRIOR TO ISSUANCE OF A LAND DISTURBANCE PERMIT. 8 - AT THE TIME OF THE PRE -CONSTRUCTION MEETING, TWO STANDARD SIGNS MUST BE INSTALLED ON EACH SIDE OF THE CONSTRUCTION ACCESS. THESE SIGNS SHOULD STATE EITHER"CONSTRUCTION ENTRANCE AHEAD" OR "TRUCKS ENTERING HIGHWAY". CONSTRUCTION SEQUENCE TO BE AS FOLLOWS: 1. CLEAR AND GRUB TO FINAL LIMITS OF CLEARING. 2. INSTALL ADDITIONAL SILT FENCE AS SHOWN ON THE PLANS. 3. BEGIN SITE GRADING OPERATIONS. 4. INSTALL SANITARY SEWER. 5. GRADE ROADWAYS TO SUBGRADE. 6. INSTALL THE PEDESTRIAN TUNNEL AND HEADWALLS ON THE ENTRANCE DRIVE (STRUCTURES 4-6). 7. INSTALL STORM SEWER PIPES AND STRUCTURES, INSTALLING INLET PROTECTION FOR THE DRAINAGE INLETS AS PROGRESSION OCCURS. 8. INSTALL WATERLINE. 9. INSTALL CURB AND GUTTER, STONE, AND PAVEMENT. 10. SEED ALL DENUDED AREAS. 11. ONCE LAND DISTURBANCE AREAS HAVE BEEN FULLY STABILIZED, CONTRACTOR SHALL REMOVE SEDIMENT TRAPS AND OTHER EC DEVICES (WITH EXCEPTION OF THE SEDIMENT BASINS) UPON APPROVAL OF ENVIRONMENTAL INSPECTOR. 12. ONCE SEDIMENT TRAPS 1 AND 5 ARE REMOVED, PERMANENT BIOFIOLTERS SHALL BE INSTALLED, RESPECTIVELY. THE SEDIMENT BASINS SHALL REMAIN AS TEMPORARY SEDIMENT BASINS UNTIL THE FUTURE APARTMENT SITE AND ADJACENT RESIDENTIAL DEVELOPMENT ARE CONSTRUCTED. ONCE THESE FUTURE SITES ARE STABILIZED, THE BASINS MAY BE CONVERTED TO PERMANENT SWMBMPS. O C O 0 � U cq U C', co m 6 CC2 O 0 06 U .may v •r-1 0 .-1 U O W U O rn� LO O u cd � pI 0 �i L) kit BRIAN C.

STEP 3 Determine the appropriate situation. The site informtaion determined in STEP 1 and STEP 2 provide enough information to determine the appropriate development situation underwhich the performance criteria will apply. Check ( ) the appropriate development situation as follows: Situation 1: This consists of land development where the existing percent impervious cover (lexlsting) is less than or equal to the average land covercondition (Iwatershed) and the proposed improvements will create a total percent impervious cover (Ipost) which is less than or equal to the average land cover condition (I watershed) Ipost Iwatershed Worksheet 1 Page 3 of 3 X Situation 2: This consists of land development where the existing percent impervious cover (lexlsting) is less than or equal to the average land covercondition (Iwatershed) and the proposed improvements will create a total percent impervious cover (lp°st) which is greaterthan the average land cover condition (Iwatershed)• lexisting 0•� < Iwatershed 16% (post 43% > Iwatershed 16% Situation 3: This consists of land development where the existing percent impervious cover (lexlsting) is greaterthan the average land covercondition (Iwatershed) lexistin¢ Iwatershed Situation 4: This consists of land development where the existing percent impervious cover(Iexst;ng) is served by an existing stormwater management BMP (s) that addresses water aual itv If the proposed development meets the criteria for development Situation 1, than the low density development is considered to be the BMP and no pollutant removal is required. The calculation procedure for Situation 1 stops here. If the proposed development meets the criteria for development Situations 2, 3 or4, then proceed to STEP 4 on the appropriate worsheet. STEP 5 Determine the relative post -development pollutant load (Lpost). Lpost = [0.05+(0.009 x Iwatershed)] x A x 2.28 (Equation 5-16) Where: Lpost = relativepost-development total phosphorus load (pounds per year) I post = post -development percent impervious cover (expressed in whole numbers) A = Applicable area (acres) Lpost = [0.05 + (0.009) x 43% )] x 83.34 x 2.28 = 83.563 Pounds per year STEP 6 Determine the relative poluutant removal requirement (RR). RR = Lpost - Lpre(watershed) RR = 83.563 - 36.863 = 46.700 Pounds per year STEP 7 Identify best management practice (BMP) for the site. 1. Determine the required pollutant removal efficiency forthe site: EFF = ( RR / Lpost) x 100 Where: EFF = required pollutant removal efficiency (percent expressed in whole numbers) RR = pollutant removal requirement (pounds peryear) Lpost = relative post -development total phosphorus load (pounds per year) EFF = 46.700 / 83.563 x 100 = 56% 2.

SET THE PLANT STRAIGHT AND IN THE CENTER OF THE PIT SO THAT APPROXIMATELY 1/8 OF THE DIAMETER OF THE ROOT BALL IS ABOVE THE FINAL GRADE. 7. MAKE SURE PLANT REMAINS STRAIGHT DURING BACKFILLING PROCEDURE. 8. NEVER COVER THE TOP OF THE BALL WITH SOIL. MOUND SOIL AROUND THE EXPOSED BALL. 9. TREES SHALL BE BRACED BY USING 2" BY 2" WHITE OAK STAKES. STAKES SHALL BE PLACED PARALLEL TO WALWAYS AND BUILDINGS. STAKES ARE TO BE EQUALLY SPACED ON THE OUTSIDE OF THE TREE BALL. UTILIZING HOSE AND WIRE THE TREE IS BRACED TO THE STAKES. 10. BECAUSE OF THE HIGH LEVELS OF NUTRIENTS IN STORMWATER RUNOFF TO BE TREATED, BIORETENTION BASIN PLANTS SHOULD NOT REQUIRE CHEMICAL FERTILIZATION PLANTING DATE GUIDELINES BALLED AND BURLAPPED AND CONTAINERIZED TREES AND SHRUBS SHOULD BE PLANTED BETWEEN MARCH 15 AND JUNE 30 OR BETWEEN SEPTEMBER 15 AND NOVEMBER 15. GROUND COVER EXCLUDING GRASSES AND LEGUMES CAN FOLLOW THE TREE AND SHRUB PLANTING DATES. GRASSES AND LEGUMES TYPICALLY SHOULD BE PLANTED IN THE SPRING OF THE YEAR.

Specific Facilities may require additional measures not discussed here. A schedule ofrecommended maintenance for bioretention areas is given in Table 3.11-5. The table gives general guidance regarding methods, frequency, and time of year for maintenance. Piano= Soil Urban plant communities tend to become very acidic due to precipitation as well as the influences of storm water runoff. For this reason, it is recommended that the application of alkaline, such as limestone, be considered once to twice a year. Testing ofthe pH ofthe organic layer and soil, should precede the limestone application to determine the amount of limestone required. Soil testing should be conducted annually so that the accumulation of toxins and heavy metals can be detected or prevented. Over a period of time, heavy metals and other toxic substances will tend to accumulate in the soil and the plants. Data from other environs such as forest buffers and gross swales suggest accumulation of toxins and heavy metals within five years of installation. However, there is nq methodology to estimate the level oftoxic materials in the bioretention areas since runoff, soil, and plant characteristics will vary from site to site. As tDe toxic substances accumulate, theplantbiologic functions maybecome impaired,andtheplant rhl experience dwarfed growth followed by mortality. The biota within the soil can also become void and the natural soil chemistry may be altered. The preventative measures would include the removal ofthe contaminated soil. In some cases, removal and disposal ofthe entire soil base as well as the plant material may be required. Mulch Bioretention areas should be mulched once the planting of trees and shrubs has occurred. Any ground cover specified as plugs may be installed once the area has been mulched. Ground cover established by seeding anal consisting of grass should not be covered with mulch. GRAPHIC SCALE 20 40 ( IN FEET ) 1 inch = 20 ft. LEGEND FINISHED GRADE AT C/L - - - - - - - - - EXIST.
