9. FOR THE TEMPORARY EROSION AND SEDIMENTATION CONTROL, THE CONTRACTOR WITH THE CO AND ENVIRONMENTAL MONITOR, SHALL ADJUST THE LOCATION, QUANTITY AND TYPE OF EROSION AND SEDIMENT CONTROL ITEMS REQUIRED BASED ON THE ACTUAL FIELD CONDITIONS ENCOUNTERED AT THE TIME OF CONSTRUCTION AND THE ACTUAL SCHEDULING AND SEQUENCING OF THE CONSTRUCTION ACTIVITIES.

INSTALLATION OF AGGREGATE TOPSOIL. PROVIDE SMOOTH TRANSITION FROM TOP OF ASPHALT TO EXISTING GRADE, MATCH EXISTING SLOPE/GRADE.

20. AREAS WHERE OVERLAY WILL BE PLACED ON EXISITNG ASPHALT AND TRANSITION TO A MILLED SURFACE, THE MILLING SHALL TAPER FROM ZERO INCHES TO TWO INCHES ON EITHER END OF SECTIONS OF MILLING TO ALLOW FOR A SMOOTH FINAL SURFACE TRANSITION (SEE SHEET NO. 5).

21. COLOR CODING WITHIN THE DRAWINGS ARE USED TO INDICATE PROPOSED AREAS OF TREATMENT. FEILD VARIFICATION WILL BE REQUIRED TO ENSURE PROPER MEASUREMENT AND

TREATMENT ACCORDING TO VDOT STANDARDS AND SCOPE OF WORK AND DRAWINGS

22. CAMPSITE PULL-INS AND PARKING AREAS ARE SUBJECT TO MINIMAL TREATMENT INCLUDING BUT NOT LIMITED TO SLURRY SEAL, OVERLAY OR FOG SEAL, UNLESS OTHERWISE INDICATED

WITHIN THE DRAWINGS.
