6. SURFACE RUNOFF FROM DISTURBED AREAS THAT IS COMPRISED OF FLOW FROM DRAINAGE AREASGREATER THAN OR EQUAL TO THREE ACRES SHALL BE CONTROLLED TO ACCOMMODATE THEANTICIPATED SEDIMENT LOADING FROM THE LAND-DISTURBING ACTIVITY. THE OUTFALL DEVICE ORSYSTEM DESIGN SHALL TAKE INTO ACCOUNT THE TOTAL DRAINAGE AREA FLOWING THROUGH THEDISTURBED AREA TO BE SERVED BY THE BASIN.

7. CUT AND FILL SLOPES SHALL BE CONSTRUCTED IN A MANNER THAT WILL MINIMIZE EROSION. SLOPESTHAT ARE FOUND TO BE ERODING EXCESSIVELY WITHIN ONE YEAR OF PERMANENT STABILIZATION SHALLBE PROVIDED WITH ADDITIONAL SLOPE STABILIZING MEASURES UNTIL THE PROBLEM IS CORRECTED.

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

9. WHENEVER WATER SEEPS FROM A SLOPE FACE, ADEQUATE DRAINAGE OR OTHER PROTECTION SHALL BEPROVIDED.

10. ALL STORM SEWER INLETS THAT ARE MADE OPERABLE DURING CONSTRUCTION SHALL BE PROTECTED SOTHAT SEDIMENT-LADEN WATER CANNOT ENTER THE CONVEYANCE SYSTEM WITHOUT FIRST BEINGFILTERED OR OTHERWISE TREATED TO REMOVE SEDIMENT.

11. BEFORE STORMWATER CONVEYANCE CHANNELS ARE MADE OPERATIONAL, ADEQUATE OUTLETPROTECTION AND ANY REQUIRED TEMPORARY OR PERMANENT CHANNEL LINING SHALL BE INSTALLED INBOTH THE CONVEYANCE CHANNEL AND RECEIVING CHANNEL.

12. WHEN WORK IN A LIVE WATERCOURSE IS PERFORMED, PRECAUTIONS SHALL BE TAKEN TO MINIMIZEENCROACHMENT, CONTROL SEDIMENT TRANSPORT, AND STABILIZE THE WORK AREA TO THE GREATESTEXTENT POSSIBLE DURING CONSTRUCTION. NONERODIBLE MATERIAL SHALL BE USED FOR THECONSTRUCTION OF CAUSEWAYS AND COFFERDAMS. EARTHEN FILL MAY BE USED FOR THESESTRUCTURES IF ARMORED BY NONERODIBLE COVER MATERIALS.

13. WHEN A LIVE WATERCOURSE MUST BE CROSSED BY CONSTRUCTION VEHICLES MORE THAN TWICE IN ANYSIX-MONTH PERIOD, A TEMPORARY STREAM CROSSING CONSTRUCTED OF NONERODIBLE MATERIALSHALL BE PROVIDED.

14. ALL APPLICABLE FEDERAL, STATE AND LOCAL REGULATIONS PERTAINING TO WORKING IN OR CROSSINGLIVE WATERCOURSES SHALL BE MET.

15. THE BED AND BANKS OF A WATERCOURSE SHALL BE STABILIZED IMMEDIATELY FOLLOWING AFTER WORKIN THE WATERCOURSE IS COMPLETED.

1. ALL SPOILS AREAS ARE TO BE RETURNED TO NATURAL GROUND AT THECOMPLETION OF THE PROJECT, FILL IS NOT PERMITTED WITHIN ANY RPA,FLOODPLAIN, OR JURISDICTIONAL WETLANDS.

2. ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL PRACTICESWILL BE CONSTRUCTED AND MAINTAINED ACCORDING TO MINIMUM STANDARDSAND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROLHANDBOOK.

3. THE CONTRACTOR SHALL INSPECT ALL EROSION CONTROL MEASURESPERIODICALLY AND AFTER EACH RUNOFF PRODUCING RAINFALL EVENT. ANYNECESSARY REPAIRS OR CLEANUP TO MAINTAIN THE EFFECTIVENESS OF THEEROSION CONTROL DEVICES SHALL BE MADE IMMEDIATELY.

PROJECT DESCRIPTION

EXISTING SITE CONDITIONSTHE EXISTING LAND ON THE EAST SIDE OF WASHINGTON HWY IS OPEN FARMLAND THAT HAS BEENDEVELOPED AS AN INDUSTRIAL PARK. IT IS MOSTLY FLAT WITH SOME EXISTING ROADSIDE DITCHES. ALLPROPOSED WORK IS TO TAKE PLACE WITHIN THE RIGHT-OF-WAY. THERE ARE NO WATERS OF THE US OREXISTING WETLANDS WITHIN THE PROPOSED LIMITS OF CONSTRUCTION. THERE SHALL BE NOUNNECESSARY DESTRUCTION OF VEGETATION OR INFRASTRUCTURE IF THE AREAS DO NOT FALL WITHINTHE LIMITS OF DISTURBANCE. SEE PLAN SHEETS FOR ANY SPECIFIC AREAS THAT ARE TO BE LEFTUNDISTURBED.

ADJACENT AREAS:THE PROPERTY ON THE EAST SIDE OF WASHIGNTON HWY IS PRIVATELY OWNED AND PART OF A SMALLINDUSTRIAL PARK.

OFF-SITE AREAS:THERE ARE NO OFF-SITE DISTURBANCES ASSOCIATED WITH THIS PROJECT. ALL OTHER WORK EXCEPTFOR TRAFFIC SIGNAL WORK WILL BE DONE WITHIN THE RIGHT-OF-WAY.

SOILS:BASED ON A USDA SOIL SURVEY, THE PREDOMINANT SOILS LOCATED WITHIN THE PROJECT LIMITS ARE:

7 ATLEE LOAM, WHICH IS A MODERATELY WELL DRAINED LOAM WITH 0 TO 4% SLOPES.47B NORFOLK FINE SANDY LOAM, WHICH IS A WELL DRAINED FINE SANDY LOAM WITH 2 TO 7% SLOPES.50B ORANGEBURG-FACEVILLE FINE SANDY LOAM, WHICH IS A WELL DRAINED FINE SANDY LOAM WITH2 TO 7% SLOPES.

CRITICAL AREAS:THERE ARE NO CRITICAL AREAS FOR THIS SITE.

WETLANDS:THERE ARE NO WETLANDS WITHIN THE PROJECT LIMITS.

EROSION AND SEDIMENT CONTROL MEASURES:UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROLPRACTICES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO MINIMUM STANDARDS ANDSPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK . THE MINIMUMSTANDARDS OF THE VESCH SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED OR APPROVED BY AVARIANCE. EACH EROSION AND SEDIMENT CONTROL MEASURE WAS SELECTED BASED ON A DETAILEDEXAMINATION OF THE EXISTING SITE CONDITIONS AND THEIR POTENTIAL CONFLICTS WITH PROPOSEDROADWAY CONSTRUCTION. THE MEASURES ARE DESIGNED TO LIMIT WETLAND IMPACTS, MINIMIZEEROSION, MAINTAIN A SAFE AND CLEAN WORK ENVIRONMENT, AND MINIMIZE IMPACTS TO EXISTING TREEGROWTH, AMONG OTHERS. AFTER THE MEASURES HAVE BEEN CONSTRUCTED, THEY SHALL BEMAINTAINED IN A TIMELY MANNER ACCORDING TO THE PROVISIONS SET FORTH IN THE VIRGINIA EROSIONAND SEDIMENT CONTROL HANDBOOK . ALL GRADED AREAS SHALL BE SEEDED WITH EITHER PERMANENT(IF GRADING IS FINAL) OR TEMPORARY SEEDING IF LEFT UNDISTURBED FOR MORE THAN SEVEN DAYS.

PERMANENT STABILIZATION:ALL AREAS DISTURBED BY CONSTRUCTION SHALL BE STABILIZED WITH PERMANENT SEEDINGIMMEDIATELY FOLLOWING FINAL GRADING. UNLESS SPECIFIED OTHERWISE, THE RECOMMENDEDPERMANENT SEEDING VARIETY IS KENTUCKY 31 TALL FESCUE ACCORDING TO STANDARD 3.32,PERMANENT SEEDING, OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK . REFER TO TABLE3.32-D IN THE VESC HANDBOOK FOR SPECIFIC SEEDING RECOMMENDATIONS BASED ON PLANTINGSEASON AND LOCATION.

MS-19 COMPLIANCE WORKSHEETIn accordance with Minimum Standard 19 of the Erosion and Sediment Control Regulations, adequacy of receiving channels or pipes must be verified byaddressing one of the following Adequacy Situations:

A. The drainage area from the project at the discharge point is less than or equal to one percent (1%) of the total drainage area at the discharge point.(Project Drainage Area and Total Drainage Area are required).

OrB. Natural channels must be analyzed to demonstrate that (1) the two-year storm will not overtop the channel banks and (2) the two-year storm will not

cause erosion of the channel bed or banks (QCapacity, Q2, and V2 are required).Or

C. Man-made channels must be analyzed to demonstrate that (1) the ten-year storm will not overtop the channel banks and (2) the two-year storm will notcause erosion of the channel bed or banks, or (3) the ten-year storm will not cause erosion of the channel bed or banks for improvements within CountyDrainage Easements (QCapacity, Q10, and V2 / V10 are required).

OrD. Pipes and storm sewer systems must be analyzed to demonstrate that the ten-year storm will be contained within the system (QCapacity, Q10, and
