CONSTRUCTION. PROVIDE NONERODIBLE MATERIAL FOR THE CONSTRUCTION OF CAUSEWAYS AND COFFERDAMS.

EARTHEN FILL MAY BE USED FOR THESE STRUCTURES IF ARMORED BY NONERODIBLE COVER MATERIALS.

MS-13: WHEN A LIVE WATERCOURSE MUST BE CROSSED BY CONSTRUCTION VEHICLES MORE THAN TWICE IN ANY

SIX-MONTH PERIOD, PROVIDE A TEMPORARY STREAM CROSSING CONSTRUCTED OF NONERODIBLE MATERIAL.

MS-14: MEET ALL APPLICABLE FEDERAL, STATE AND LOCAL REGULATIONS PERTAINING TO WORKING IN OR CROSSING LIVE

WATERCOURSES.

MS-15: STABILIZE THE BED AND BANKS OF A WATERCOURSE IMMEDIATELY FOLLOWING AFTER WORK IN THE

WATERCOURSE IS COMPLETED.

MS-16: UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THESE STANDARDS IN ADDITION TO

OTHER APPLICABLE CRITERIA:

A. OPEN NO MORE THAN 500 LINEAR FEET OF TRENCH AT ONE TIME.

B. PLACE EXCAVATED MATERIAL ON THE UPHILL SIDE OF TRENCHES

C. FILTER EFFLUENT FROM DEWATERING OPERATIONS OR PASS THROUGH AN APPROVED SEDIMENT TRAPPING

DEVICE, OR BOTH, AND DISCHARGE IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING STREAMS

OR OFFSITE PROPERTY.

D. MATERIAL USED FOR BACKFILLING TRENCHES SHALL BE PROPERLY COMPACTED IN ORDER TO MINIMIZE

EROSION AND PROMOTE STABILIZATION.

E. ACCOMPLISH RESTABILIZATION IN ACCORDANCE WITH THESE REGULATIONS.

F. COMPLY WITH ALL APPLICABLE SAFETY REGULATIONS.

MS-17: WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED PUBLIC ROADS, MAKE PROVISIONS TO

MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO THE PAVED SURFACE. WHERE

SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, CLEAN THE ROAD THOROUGHLY AT THE END OF

EACH DAY. REMOVE SEDIMENT FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORT TO A SEDIMENT

CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS

MANNER.

MS-18: REMOVE ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES WITHIN 30 DAYS AFTER FINAL SITE

STABILIZATION BUT ONLY AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, AND ONLY AFTER

AUTHORIZED BY THE SITE INSPECTOR. PERMANENTLY STABILIZE TRAPPED SEDIMENT AND THE DISTURBED SOIL

AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES TO PREVENT FURTHER EROSION AND

SEDIMENTATION.

MS-19: PROPERTIES AND WATERWAYS DOWNSTREAM FROM DEVELOPMENT SITES SHALL BE PROTECTED FROM SEDIMENT

DEPOSITION, EROSION AND DAMAGE DUE TO INCREASES IN VOLUME, VELOCITY AND PEAK FLOW RATE OF

STORMWATER RUNOFF FOR THE STATED FREQUENCY STORM OF 24-HOUR DURATION IN ACCORDANCE WITH THE

FOLLOWING STANDARDS AND CRITERIA. STREAM RESTORATION AND RELOCATION PROJECTS THAT INCORPORATE

NATURAL CHANNEL DESIGN CONCEPTS ARE NOT MAN-MADE CHANNELS AND SHALL BE EXEMPT FROM ANY FLOW

RATE CAPACITY AND VELOCITY REQUIREMENTS FOR NATURAL OR MAN-MADE CHANNELS:

A. CONCENTRATED STORMWATER RUNOFF LEAVING A DEVELOPMENT SITE SHALL BE DISCHARGED DIRECTLY

INTO AN ADEQUATE NATURAL OR MAN-MADE RECEIVING CHANNEL, PIPE OR STORM SEWER SYSTEM. FOR

THOSE SITES WHERE RUNOFF IS DISCHARGED INTO A PIPE OR PIPE SYSTEM, DOWNSTREAM STABILITY

ANALYSES AT THE OUTFALL OF THE PIPE OR PIPE SYSTEM SHALL BE PERFORMED.

B. ADEQUACY OF ALL CHANNELS AND PIPES SHALL BE VERIFIED IN THE FOLLOWING MANNER:

1. THE APPLICANT SHALL DEMONSTRATE THAT THE TOTAL DRAINAGE AREA TO THE POINT OF ANALYSIS

WITHIN THE CHANNEL IS ONE HUNDRED TIMES GREATER THAN THE CONTRIBUTING DRAINAGE AREA OF

THE PROJECT IN QUESTION.

2.

a. NATURAL CHANNELS SHALL BE ANALYZED BY THE USE OF A TWO YEAR STORM TO VERIFY THAT

STORMWATER WILL NOT OVERTOP CHANNEL BANKS NOR CAUSE EROSION OF CHANNEL BED OR

BANKS.

b. ALL PREVIOUSLY CONSTRUCTED MAN-MADE CHANNELS SHALL BE ANALYZED BY THE USE OF A

TEN-YEAR STORM TO VERIFY THAT STORMWATER WILL NOT OVERTOP ITS BANKS AND BY THE USE OF

A TWO-YEAR STORM TO DEMONSTRATE THAT STORMWATER WILL NOT CAUSE EROSION OF CHANNEL

BED OR BANKS.

c. PIPES AND STORM SEWER SYSTEMS SHALL BE ANALYZED BY THE USE OF A TEN-YEAR STORM TO

VERIFY THAT STORMWATER WILL BE CONTAINED WITHIN THE PIPE OR SYSTEM.

C. IF EXISTING NATURAL RECEIVING CHANNELS OR PREVIOUSLY CONSTRUCTED MAN-MADE CHANNELS OR PIPES

ARE NOT ADEQUATE, THE APPLICANT SHALL:

1. IMPROVE THE CHANNELS TO A CONDITION WHERE A TEN-YEAR FREQUENCY STORM WILL NOT OVERTOP

THE BANKS AND A TWO-YEAR FREQUENCY STORM WILL NOT CAUSE EROSION TO THE CHANNEL BED OR

BANKS; OR

2. IMPROVE THE PIPE OR PIPE SYSTEM TO A CONDITION WHERE THE TEN-YEAR FREQUENCY STORM IS

CONTAINED WITHIN THE APPURTENANCES; OR

3. DEVELOP A SITE DESIGN THAT WILL NOT CAUSE THE PRE-DEVELOPMENT PEAK RUNOFF RATE FROM A

TWO-YEAR STORM TO INCREASE WHEN RUNOFF OUTFALLS INTO A NATURAL CHANNEL OR WILL NOT

CAUSE THE PRE-DEVELOPMENT PEAK RUNOFF RATE FROM A TEN-YEAR STORM TO INCREASE WHEN

RUNOFF OUTFALLS INTO A MAN-MADE CHANNEL.

4. PROVIDE A COMBINATION OF CHANNEL IMPROVEMENT, STORMWATER DETENTION/RETENTION OR OTHER

MEASURES WHICH IS SATISFACTORY TO THE PLAN APPROVING AUTHORITY TO PREVENT DOWNSTREAM

EROSION.

D. THE APPLICANT SHALL PROVIDE EVIDENCE OF PERMISSION TO MAKE THE IMPROVEMENTS.

E. ALL HYDROLOGIC ANALYSES SHALL BE BASED ON THE EXISTING WATERSHED CHARACTERISTICS AND THE

ULTIMATE DEVELOPMENT CONDITION OF THE SUBJECT PROJECT.

EROSION AND SEDIMENT CONTROL NARRATIVE

PROJECT DESCRIPTION

THIS PROJECT INCLUDES THE INSTALLATION OF DRY UTILITIES AS REQUIRED FOR THE NEW LOUDOUN COUNTY JUVENILE

DETENTION CENTER (JDC). THE TOTAL DISTURBED AREA IS 1.30 AC (56,628 SF) FOR THIS UTILITY PLAN.

EXISTING SITE CONDITIONS

THE SITE IS ADJACENT TO GOURLEY TRANSIT DR, NORTH OF THE JDC SITE. THE EXISTING GRADE WITHIN THE PROJECT AREA IS

FLAT TO MODERATELY SLOPED (0-5%). THE SITE IS CURRENTLY UNDEVELOPED, WITH THE ONLY IMPROVEMENTS BEING AN

ASPHALT TRAIL AND EXISTING GOURLEY TRANSIT DR.

ADJACENT PROPERTY

THE PROJECT AREA IS A PART OF THE OVERALL PARCEL (APPROX. 672 ACRES) IDENTIFIED AS TAX MAP NUMBER 60////////12/, AND IS

PART OF THE LOUDOUN COUNTY GOVERNMENT SUPPORT CENTER. THIS PROJECT AREA IS BORDERED TO THE NORTH BY

LOUDOUN COUNTY FIRE AND RESCUE TRAINING CENTER AND THE LOUDOUN COUNTY ADULT DETENTION CENTER TO THE NORTH

AND WEST, TO THE SOUTH BY THE GOURLEY TRANSIT DRIVE, AND TO THE EAST BY A SYCOLIN ROAD.

OFF-SITE AREAS

THERE ARE NO OFF-SITE AREAS BEING DISTURBED WITH THIS PLAN. SHOULD THE NEED ARISE TO GRADE OFF-SITE, OR OBTAIN

MATERIAL FROM A BORROW AREA, THE AREA MUST BE COVERED BY A VALID GRADING PERMIT.

SEE SHEET DU3.0 & DU3.1 FOR THE COUNTY SOILS MAPPING & THE COUNTY SOILS SUMMARY.

CRITICAL EROSION AREAS

THE DISTURBED AREA WAS PREVIOUSLY GRADED WITH THE REALIGNMENT OF GOURLEY TRANSIT DRIVE.

THERE ARE NO CRITICAL AREAS WITHIN PROJECT LIMITS.

STORM WATER RUNOFF CONSIDERATION

THIS IS A LINEAR PROJECT WITH NO ADDITIONAL IMPERVIOUS AREA PROPOSED. SITE TO BE FULLY STABILIZED AT END OF EACH

WORKING DAY.

EROSION CONTROL PROGRAM

EROSION CONTROL SHALL BE MAXIMIZED THROUGH RAPID STABILIZATION OF THE DISTURBED AREAS AND BY DIVERTING CLEAN

WATER AND EROSIVE FLOWS AROUND OR THROUGH DISTURBED AREAS IN A NON-EROSIVE MANNER NOT MORE THAN 7 CALENDAR

DAYS ARE TO ELAPSE WITH ANY DISTURBED AREA REMAINING DENUDED. TEMPORARY COVER, BY SEEDING AND/OR MULCHING,

SHALL BE APPLIED TO AREAS THAT WILL BE EXPOSED FOR A PERIOD OF GREATER THAN 7 DAYS, BEFORE PERMANENT

STABILIZATION PERMANENT COVER SHOULD BE PROVIDED OVER ALL DISTURBED AREAS AS SOON AS POSSIBLE UPON ACHIEVING

FINAL GRADE, BY MEANS OF SEEDING AND MULCHING. SODDING AND PEGGING, PAVING. OR AS OTHERWISE DIRECTED BY THE

PLAN. LIKEWISE, ALL STOCKPILES SHALL BE STABILIZED WITHIN 7 DAYS OF ACHIEVING FINAL GRADES. UTILITY TRENCHES SHALL

BE SEEDED AND MULCHED WITHIN 7 DAYS AFTER BACKFILLING TO THE FINISHED GRADE. ALL TEMPORARY DIVERSION DIKES SHALL

BE SEEDED AND MULCHED IMMEDIATELY AFTER CONSTRUCTION.

SEDIMENT CONTROL PROGRAM

SEDIMENT CONTROL SHALL BE ACCOMPLISHED THROUGH RAPID STABILIZATION AND BY THE INSTALLATION OF MECHANICAL

DEVICES, AS SHOWN ON THE PHASE I PLAN.

UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE

CONSTRUCTED AND MAINTAINED ACCORDING TO MINIMUM STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION &

SEDIMENT CONTROL HANDBOOK. THE MINIMUM STANDARDS OF THE VESCH SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED

OR APPROVED BY A VARIANCE BY LOCAL AUTHORITIES HAVING JURISDICTION.

ALL NON-PAVED AREAS DISTURBED BY CONSTRUCTION SHALL BE STABILIZED WITH PERMANENT SEEDING IMMEDIATELY

FOLLOWING FINISH GRADING. SEEDING SHALL BE IN ACCORDANCE WITH STD. & SPEC. 3.32, PERMANENT SEEDING. SEED TYPE

SHALL BE AS SPECIFIED FOR "MINIMUM CARE LAWNS" AND "GENERAL SLOPES" IN THE HANDBOOK. MULCH (STRAW OR FIBER)

SHALL BE USED ON ALL SEEDED SURFACES. IN ALL SEEDING OPERATIONS SEED, FERTILIZER AND LIME SHALL BE APPLIED PRIOR

TO MULCHING.

ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CHECKED DAILY AND AFTER EACH RUN-OFF PRODUCING RAINFALL.

THE FOLLOWING ITEMS SHALL BE CHECKED IN PARTICULAR:

A. CHECK THE SILT FENCE AFTER EVERY STORM EVENT TO ENSURE EFFECTIVE OPERATION AND REMOVE SEDIMENT WHEN

THE LEVEL OF SEDIMENT DEPOSITION REACHES HALF WAY TO THE TOP OF THE BARRIER.

B. CHECK THE SILT FENCE BARRIER FOR UNDERMINING OR DETERIORATION OF THE FABRIC. REMOVE SEDIMENT WHEN THE

LEVEL OF SEDIMENT DEPOSITION REACHES HALF WAY TO THE TOP OF THE BARRIER.

C. CHECK THE GRAVEL INLET PROTECTION FOR SEDIMENT BUILDUP WHICH WILL PREVENT DRAINAGE. IF THE GRAVEL IS

CLOGGED BY SEDIMENT; REMOVE AND CLEAN, OR REPLACE.

D. CHECK THE SEEDING AREAS TO ENSURE THAT A STAND OF GRASS IS MAINTAINED. FERTILIZE AND RESEED AS NEEDED.

E. SEE MINIMUM STANDARDS FOR ADDITIONAL INFORMATION.
