EROSION AND SEDIMENT CONTROL NARRATIVE

EROSION AND SEDIMENT CONTROL NOTES

1. THE PURPOSE OF THE EROSION CONTROL MEASURES SHOWN ON THESE PLANS SHALL BE TO PRECLUDE THE TRANSPORT OF ALL WATERBORNE SEDIMENTS RESULTING FROM CONSTRUCTION ACTIVITIES FROM ENTERING ONTO ADJACENT PROPERTIES OR STATE WATERS. IF FIELD INSPECTION REVEALS THE INADEQUACY OF THE PLAN TO CONFINE SEDIMENT TO THE PROJECT SITE, APPROPRIATE MODIFICATIONS SHALL BE MADE TO CORRECT ANY PLAN DEFICIENCIES. IN ADDITION TO THESE NOTES, ALL PROVISIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL REGULATION SHALL APPLY TO THIS PROJECT.

2. WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY 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 DISPOSAL AREA.

3. ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE INSTALLED AND MAINTAINED IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, THIRD EDITION, 1992 . THE CONTRACTOR SHALL BE THOROUGHLY FAMILIAR WITH ALL APPLICABLE MEASURES CONTAINED THEREIN WHICH MAY BE PERTINENT TO THIS PROJECT.

4. ALL APPLICABLE FEDERAL, STATE AND LOCAL REGULATIONS PERTAINING TO WORKING IN OR CROSSING A LIVE WATERCOURSE SHALL BE MET.

5. PERIODIC INSPECTIONS OF ALL EROSION CONTROL MEASURES SHALL BE MADE BY THE CONTRACTOR TO ASSESS THEIR CONDITION. INSPECTIONS SHALL BE CONDUCTED AT LEAST ONCE EVERY 14 CALENDAR DAYS AND WITHIN 48 HOURS FOLLOWING ANY RUNOFF PRODUCING STORM EVENT OR EVERY 7 CALENDAR DAYS REGARDLESS OF WEATHER (AS DETERMINED AND SPECIFIED VSMP PERMITTING AND SWPPP). THIS INCLUDES INSPECTION AFTER EVERY ERODIBLE RAINFALL EVENT AND THE REPAIR OF MEASURES DAMAGED BY SUB-CONTRACTORS. ANY NECESSARY REPAIRS OR CLEAN UP TO MAINTAIN THE EFFECTIVENESS OF

THE EROSION CONTROL DEVICES SHALL BE MADE IMMEDIATELY.

6. SEDIMENT CONTROL MEASURES MAY REQUIRE MINOR FIELD ADJUSTMENTS AT THE TIME OF CONSTRUCTION TO INSURE THEIR INTENDED PURPOSE IS ACCOMPLISHED. APPROVAL BY THE ENGINEER OR SITE

INSPECTOR WILL BE REQUIRED FOR ANY DEVIATIONS FROM THE APPROVED PLANS.

7. ADDITIONAL EROSION CONTROL DEVICES MAY BE REQUIRED BY THE STATE INSPECTOR, ENGINEER, OWNER, OR HIS DESIGNATED AGENT IF DEEMED NECESSARY.

8. ALL EROSION CONTROL DEVICES SHALL BE IN PLACE AND FUNCTIONAL AT ALL TIMES AND IF REMOVED FOR CONSTRUCTION PROGRESS, SHALL BE REPLACED BY THE CLOSE OF EACH WORKDAY.

9. SURFACE FLOWS OVER CUT AND FILL SLOPES SHALL BE CONTROLLED BY EITHER REDIRECTING FLOWS FROM TRANSVERSING THE SLOPES OR BY INSTALLING MECHANICAL DEVICES TO SAFELY LOWER WATER

DOWNSLOPE WITHOUT CAUSING EROSION.

10. THE CONTRACTOR SHALL PLACE SOIL STOCKPILES AT THE LOCATIONS SHOWN ON THIS PLAN OR AS DIRECTED BY THE ENGINEER. SOIL STOCKPILES SHALL BE STABILIZED OR PROTECTED WITH SEDIMENT TRAPPING MEASURES. OFF-SITE WASTE OR BORROW AREAS SHALL BE APPROVED PRIOR TO THE IMPORT OF ANY BORROW OR EXPORT OF ANY WASTE TO OR FROM THE PROJECT SITE.

11. ALL SLOPES SHALL REQUIRE THE USE OF EROSION CONTROL BLANKETS TO AID IN THE ESTABLISHMENT OF A VEGETATIVE COVER. INSTALLATION SHALL BE IN ACCORDANCE WITH SPECIFICATION 3.36 (B/M) AND

MANUFACTURER'S INSTRUCTIONS. NO SLOPES SHALL BE CREATED STEEPER THAN 2:1.

12. THE CONTRACTOR SHALL COMPLETE DRAINAGE FACILITIES WITHIN 30 DAYS FOLLOWING COMPLETION OF ROUGH GRADING AT ANY POINT WITHIN THE PROJECT. OUTFALL CHANNELS FROM DRAINAGE STRUCTURES SHALL BE STABILIZED IMMEDIATELY AFTER CONSTRUCTION OF SAME. THIS INCLUDES INSTALLATION OF EROSION CONTROL STONE OR PAVED DITCHES WHERE REQUIRED.

13. PERMANENT OR TEMPORARY SOIL STABILIZATION MUST BE APPLIED TO ALL DENUDED AREAS WITHIN 7 DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. SOIL STABILIZATION MUST ALSO BE APPLIED TO DENUDED AREAS WHICH MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT (UNDISTURBED) FOR LONGER THAN 30 DAYS. SOIL STABILIZATION MEASURES INCLUDE VEGETATIVE ESTABLISHMENT

OR MULCHING.

14. IF DISTURBED AREA STABILIZATION IS TO BE ACCOMPLISHED DURING THE MONTHS OF DECEMBER, JANUARY, OR FEBRUARY, STABILIZATION SHALL CONSIST OF MULCHING IN ACCORDANCE WITH SPECIFICATION

3.35 OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK THIRD EDITION, 1992 . SEEDING WILL THEN TAKE PLACE AS SOON AS THE SEASON PERMITS.

15. THE TERM SEEDING, FINAL VEGETATIVE COVER OR STABILIZATION, ON THIS PLAN SHALL MEAN THE SUCCESSFUL GERMINATION AND ESTABLISHMENT OF A STABLE COVER FROM A PROPERLY PREPARED SEEDBED CONTAINING THE SPECIFIED AMOUNTS OF SEED AND FERTILIZER IN ACCORDANCE WITH THE SEEDING SCHEDULE LOCATED ON SHEET 5.

16. TEMPORARY EROSION CONTROL MEASURES ARE NOT TO BE REMOVED UNTIL ALL DISTURBED AREAS ARE STABILIZED. AFTER STABILIZATION IS COMPLETE, ALL MEASURES SHALL BE REMOVED WITHIN 30 DAYS.

TRAPPED SEDIMENT SHALL BE SPREAD AND SEEDED.

PROJECT DESCRIPTION

THIS PLAN ADDRESSES EROSION AND SEDIMENT CONTROL MEASURES ASSOCIATED WITH THE PROPOSED SPOIL SITE. NO SPOIL ACTIVITY IS PROPOSED AT THIS TIME, BUT THIS PLAN IS INTENDED TO PROVIDE A

FRAMEWORK FOR PROJECT COMPLIANCE WHEN NECESSARY IN THE FUTURE

THE CONTRIBUTING DRAINAGE AREA TO THE SPOIL SITE IS APPROXIMATELY 2.4 ACRES. APPROXIMATELY 0.78 ACRES OF LAND DISTURBANCE MAXIMUM ARE PROPOSED DURING THE SPOIL ACTIVITIES

EXISTING CONDITIONS

EXISTING CONDITIONS CONSIST OF PAVED ROADS TO THE NORTH AND SOUTH, AND WOODED AREAS TO THE EAST AND WEST.

ADJACENT AREAS

ADJACENT ROADWAYS WILL BE PROTECTED THROUGH THE USE OF A CONSTRUCTION ENTRANCE. DOWNSTREAM CHANNELS WILL BE PROTECTED BY PROPOSED E&S MEASURES AS SPECIFIED ON SHEET 2, MAINLY

CONSISTING OF A SEDIMENT TRAP.

PERMANENT STORMWATER CONSIDERATIONS

THE ULTIMATE OUTFALL FOR THE PROPOSED SPOIL SITE IS LOCATED IN THE SOUTHEAST CORNER OF THE PROJECT SITE TO AN EXISTING ROADSIDE DITCH ALONG E. 16TH . ALL SITE DISCHARGES ARE SHEET FLOWS.

NO INCREASE TO FLOWS ARE EXPECTED (SEE SUMMARY THIS SHEET).

SOILS

A SOILS TABLE HAS BEEN PROVIDED ON SHEET 2 OF THIS PLAN SET. THE PROJECT AREA IS GENERALLY CHARACTERIZED BY TYPE "B" APPLING URBAN LAND COMPLEX SOILS WITH A 0-7% SLOPE ADDITIONAL

GEOTECHNICAL INFORMATION HAS BEEN PROVIDED BY BLUE RIDGE GEOTECHNICAL, LLC.

CRITICAL AREAS

CRITICAL AREAS INCLUDE THE SPOIL PILES WHICH COULD POTENTIALLY LEAD TO RILL AND GULLY EROSION. PROPOSED STOCKPILE AREAS WILL BE TREATED WITH EROSION AND SEDIMENT CONTROL MEASURES AS

SHOWN ON SHEET 2.

STRUCTURAL PRACTICES

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 AND SEDIMENT CONTROL HANDBOOK, THIRD EDITION, 1992 . THE MINIMUM STANDARDS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL REGULATIONS, LATEST EDITION SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED OR APPROVED BY A VARIANCE, IN WRITING.

1. TEMPORARY STONE CONSTRUCTION ENTRANCE - STD. & SPEC. 3.02 - CONSTRUCTION ENTRANCES SHALL BE EMPLOYED TO REDUCE THE AMOUNT OF MATERIAL TRANSPORTED OFF-SITE BY CONSTRUCTION VEHICLES. THE CONSTRUCTION ENTRANCES SHALL BE MAINTAINED AT THE LOCATION SHOWN ON SHEET 2 FOR THE DURATION OF THE CONSTRUCTION AND STABILIZATION.

2. CONSTRUCTION ROAD STABILIZATION - STD. & SPEC. 3.03 - CONSTRUCTION ROAD STABILIZATION SHALL BE APPLIED TO ALL ACCESS ROUTES THROUGH THE PROJECT SITE TO REDUCE EROSION BY

CONSTRUCTION TRAFFIC.

3. SILT FENCE - STD. & SPEC. 3.05 - SILT FENCE SHALL BE PLACED AS SHOWN IN THESE PLANS TO PREVENT SEDIMENT TRANSPORT OFFSITE. WIRE SUPPORT SHALL BE USED.

NON-STRUCTURAL PRACTICES

1. TEMPORARY SEEDING - STD. & SPEC. 3.31 - ALL EXPOSED SOIL SURFACES THAT ARE NOT TO BE FINE-GRADED FOR PERIODS LONGER THAN 30 DAYS BUT LESS THAN ONE YEAR SHALL RECEIVE TEMPORARY SEEDING. SELECTION OF THE TEMPORARY SEED MIXTURE SHALL BE IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, THIRD EDITION, 1992 AS REFERENCED ON THIS SHEET.

2. PERMANENT SEEDING - STD. & SPEC. 3.32 - PERMANENT SEEDING SHALL BE USED TO STABILIZE DISTURBED AREAS BROUGHT TO FINAL GRADE BY ESTABLISHING PERENNIAL VEGETATIVE COVER. SELECTION OF THE PERMANENT SEED MIXTURE SHALL BE IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, THIRD EDITION, 1992 AS REFERENCED ON THIS SHEET. ADDITIONALLY PERMANENT SEEDING SHALL BE USED FOR AREAS NOT YET COMPLETE BUT TO BE DORMANT FOR MORE THAN ONE YEAR.

3. MULCHING - STD. & SPEC. 3.35 - AREAS WHICH HAVE BEEN PERMANENTLY OR TEMPORARILY SEEDED SHOULD BE MULCHED IMMEDIATELY FOLLOWING SEEDING. MULCHING SHALL BE USED IN FALL FOR WINTER

COVER AND DURING HOT AND DRY SUMMER MONTHS.

MAINTENANCE PRACTICES

IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CHECKED DAILY AND AFTER EACH SIGNIFICANT RAINFALL BY THE CONTRACTOR. THE FOLLOWING ITEMS WILL BE CHECKED IN

PARTICULAR:

3.02 - TEMPORARY STONE CONSTRUCTION ENTRANCE - THE ENTRANCES SHALL BE MAINTAINED IN A CONDITION WHICH WILL PREVENT TRACKING OR FLOW OF MUD ONTO PUBLIC RIGHTS-OF-WAY. THIS MAY REQUIRE PERIODICALLY TOPDRESSING THE ENTRANCE WITH ADDITIONAL STONE OR WASHING THE EXISTING STONE.

3.03 - CONSTRUCTION ROAD STABILIZATION - BOTH TEMPORARY AND PERMANENT ROADS MAY REQUIRE PERIODIC TOP DRESSING WITH NEW GRAVEL. SEEDED AREAS ADJACENT TO THE ROADS SHOULD BE CHECKED PERIODICALLY TO ENSURE THAT A VIGOROUS STAND OF VEGETATION IS MAINTAINED.

EROSION AND SEDIMENT CONTROL MINIMUM STANDARDS

THE INTENT OF THIS SECTION IS TO SUMMARIZE HOW THE EROSION AND SEDIMENT CONTROL MEASURES PROPOSED IN THE EROSION AND SEDIMENT CONTROL PLAN SATISFY THE 19 MINIMUM STANDARDS SET FORTH IN THE VIRGINIA EROSION AND SEDIMENT CONTROL REGULATIONS (4VAC50-30-40). THE FOLLOWING IS A BRIEF SYNOPSIS OF THE MINIMUM STANDARDS (MS) AND HOW THEY ARE ADDRESSED IN THE PLAN:

MS-1 STABILIZATION OF DENUDED AREAS - WITHIN SEVEN DAYS, PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS THAT MAY REMAIN DORMANT FOR LONGER THAN 30 DAYS.

TEMPORARY AND PERMANENT SEEDING, MULCHING, BLANKETS AND MATTING, AND RIPRAP ARE SPECIFIED IN THE PLAN FOR STABILIZATION OF DENUDED AREAS.

MS-2 STABILIZATION OF SOIL STOCKPILES - DURING CONSTRUCTION, SOIL STOCKPILES AND BORROW AREAS SHALL BE STABILIZED OR PROTECTED WITH SEDIMENT TRAPPING MEASURES, (SEDIMENT TRAP).

MS-3 ESTABLISHMENT OF PERMANENT VEGETATION - A PERMANENT VEGETATIVE COVER SHALL BE ESTABLISHED ON DENUDED AREAS NOT OTHERWISE PERMANENTLY STABILIZED. PERMANENT VEGETATION SHALL NOT BE CONSIDERED ESTABLISHED UNTIL A GROUND COVER IS ACHIEVED THAT IS UNIFORM, MATURE ENOUGH TO SURVIVE, AND WILL INHIBIT EROSION.

MS-4 TIMING AND STABILIZATION OF SEDIMENT TRAPPING MEASURES - ALL SEDIMENT TRAPPING MEASURES (INCLUDING SEDIMEN TRAP) SHALL BE CONSTRUCTED AS A FIRST STEP IN ANY LAND-DISTURBING ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE.

MS-5 STABILIZATION OF EARTHEN STRUCTURES - STABILIZATION MEASURES SHALL BE APPLIED TO EARTHEN STRUCTURES IMMEDIATELY AFTER INSTALLATION AS SPECIFIED IN THE PLAN.

MS-6 SEDIMENT TRAP AND BASINS - SEDIMENT BASINS ARE NOT USED IN THIS PLAN. THE SEDIMENT TRAP SHALL CONTROL DRAINAGE AREAS LESS THAN TO THREE ACRES. THE MINIMUM STORAGE CAPACITY

SHALL BE 134 CUBIC YARDS PER ACRE OF DRAINAGE AREA.

MS-7 DESIGN, CONSTRUCTION, AND STABILIZATION OF CUT AND FILL SLOPES - CUT AND FILL SLOPES SHALL BE DESIGNED AND CONSTRUCTED IN A MANNER THAT WILL MINIMIZE EROSION. MOST SLOPES ARE PROPOSED TO BE STABILIZED WITH BLANKETING AND MATTING AS SHOWN ON THE E&S PLAN. SLOPES FOUND TO BE ERODING EXCESSIVELY WITHIN ONE YEAR OF PERMANENT STABILIZATION SHALL BE PROVIDED

WITH ADDITIONAL SLOPE STABILIZING MEASURES UNTIL THE PROBLEM IS CORRECTED.

MS-8 CONCENTRATED RUNOFF DOWN SLOPES - CONCENTRATED RUNOFF SHALL NOT FLOW DOWN CUT OR FILL SLOPES UNLESS CONTAINED WITHIN AN ADEQUATE TEMPORARY OR PERMANENT CHANNEL, FLUME, OR SLOPE DRAIN STRUCTURE.

MS-9 ADEQUATE DRAINAGE PROTECTION FROM WATER SEEPS - IF THE CONTRACTOR IDENTIFIES WATER SEEPAGE FROM A SLOPE FACE, ADEQUATE DRAINAGE PER VESCH 3.28 OR OTHER APPROPRIATE PROTECTION

SHALL BE PROVIDED.

MS-10 STORM SEWER INLET PROTECTION - NOT APPLICABLE FOR THIS PLAN SINCE THERE ARE NO STORM SEWER INLETS AFFECTED BY THE PROPOSED CONSTRUCTION.

MS-11 STORMWATER CONVEYANCE PROTECTION - BEFORE NEWLY CONSTRUCTED STORMWATER CONVEYANCE CHANNELS OR PIPES ARE MADE OPERATIONAL, ADEQUATE OUTLET PROTECTION AND ANY REQUIRED

TEMPORARY OR PERMANENT CHANNEL LINING SHALL BE INSTALLED.

MS-12 WORK IN LIVE WATERCOURSE - THERE ARE NO WATERCOURSES LOCATED WITHIN THE PROJECT AREA.

MS-13 CROSSING LIVE WATERCOURSE - NONE OF THE PROPOSED SPOIL ACTIVITY IS EXPECTED TO CROSS A LIVE WATERCOURSE.

MS-14 REGULATION OF WATERCOURSE CROSSING - NO IMPACTS TO WATERCOURSES ARE ANTICIPATED FOR THIS PROJECT. SHOULD ANY IMPACTS TO WATERCOURSES BECOME NECESSARY, PROPER PERMITS

MUST BE OBTAINED PRIOR TO CONSTRUCTION.

MS-15 STABILIZATION OF WATERCOURSE - THERE ARE NO WATERCOURSES LOCATED WITHIN THE PROJECT AREA.

MS-16 UNDERGROUND UTILITY LINE INSTALLATION - NO UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN THIS PLAN.

MS-17 VEHICULAR SEDIMENT TRACKING - WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED OR PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO THE ROADWAY. WHERE SEDIMENT IS TRANSPORTED INTO A PAVED OR PUBLIC ROAD SURFACE, THE ROAD SURFACE 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.

MS-18 REMOVAL OF TEMPORARY MEASURES - ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER THE FINAL SITE STABILIZATION OR WHEN TEMPORARY

MEASURES ARE NO LONGER NEEDED.

MS-19 STORMWATER MANAGEMENT - THE PROPOSED SITE IMPROVEMENTS ARE NOT EXPECTED TO INCREASE HYDROLOGIC CONDITIONS AT THE SITE OUTFALL (SEE SUMMARY THIS SHEET). SITE DISCHARGES ARE NON-CONCENTRATED SHEET FLOWS TO AN EXISTING ROAD SIDE DITCH ALONG E. 16TH ST. REFER TO PERMANENT STORWMATER CONSIDERATIONS SECTION OF THE EROSION AND SEDIMENT CONTROL NARRATIVE
