1. OBTAIN GRADING/EROSION CONTROL PLAN APPROVAL FROM THE CITY OF CHARLOTTE ENGINEERING DEPARTMENT.
2. SET UP A ON -SITE PRE -CONSTRUCTION CONFERENCE WITH EROSION CONTROL INSPECTOR OF THE CITY ENGINEERING
DEPARTMENT TO DISCUSS EROSION CONTROL MEASURES. FAILURE TO SCHEDULE SUCH CONFERENCE 48 HOURS PRIOR TO
ANY LAND DISTURBING ACTIVITY IS A VIOLATION OF CHAPTER 17 OF THE CITY CODE AND IS SUBJECT TO FINE.
3. THE CONTRACTOR SHALL DILIGENTLY AND CONTINUOUSLY MAINTAIN ALL EROSION CONTROL DEVICES AND STRUCTURES.
4. STAKE CLEARING LIMIT, INSTALL TREE PROTECTION FENCE, SILT FENCE, INLET PROTECTION ON EXISTING STORM STRUCTURES
IF APPLICABLE, SEDIMENT SKIMMER BASINS, TEMPORARY DIVERSION DITCHES, CLEAN WATER BYPASS CHANNEL, AND OTHER
MEASURES AS SHOWN ON PLANS. CLEARING ONLY AS NECESSARY TO INSTALL THESE DEVICES. CONTRACTOR SHALL
DILIGENTLY AND CONTINUOUSLY MAINTAIN ALL TREE -SAVE UNDISTURBED AND NATURAL AREAS AS SHOWN ON PLANTING PLAN
SHEETS Cl-4,-5,-6 BY ADHERING TO SPECIFICATIONS AND LOCATIONS FOR SILT FENCE TREE- PROTECTION FENCE SUPER
SILT -FENCE, AND/OR COMBINATION WITH TREE PROTECTION FENCE OF EACH AS SHOWN ON INITIAL EROSION CONTROL PLAN,
SHEETS C4-1 THRU C4-3.
4.1. FOR INITIAL EC PHASE, CONTRACTOR TO INSTALL STORM CULVERTS #1-60, #1-61; #3-50, #3-51, WITH ENDWALL ON BOTH
SIDES, PER CULVERT PLAN SHEET C3-3.
4.1.1. STREAMS FOR BOTH CULVERTS ARE INTERMITTENT TYPE. IF CULVERT IS NOT ABLE TO BE COMPLETELY INSTALLED
WHEN THERE IS NO STREAM FLOW, REFER TO AND UTILIZE THE PUMP AROUND AND COFFER DAM DETAILS ON THE
CULVERT PLAN SHEET C3-3..
4.1.2. FILL TO BE PLACED ON TOP OF CULVERT ADEQUATELY TO SUPPORT CONSTRUCTION TRAFFIC; A MINIMUM FILL OF 2' IS
CLARIFIED BY THE CONTOURS OVER THE CULVERTS ON THE INITIAL CONDITION E&C PLAN.
4.2. CONTRACTOR MAY CUT ONLY AS NECESSARY TO FILL THE INITIAL SKIMMER BASINS EMBANKMENTS AND CULVERTS
CROSSINGS.
4.3. BRIGHTWATER PHASE 1 DEVELOPMENT TEMPORARY SKIMMER BASINS #2 & #7 MAY REMAIN TO SERVE PART OF PHASE 2
CONSTRUCTION DRAINAGE AREA.
5. FOR INITIAL CONSTRUCTION OF SEDIMENT SKIMMER BASINS SHALL INCLUDE OUTLET STORM PIPES AND STRUCTURES THAT
SHALL MEET FINAL (PERMANENT) DESIGN CRITERIA, BASINS 1 & 3. REFER TO SHEET C4-3 FOR MORE INFORMATION AT EACH
BASIN. TEMPORARY SKIMMER BASINS ARE TO BE CONSTRUCTED TO SAME CONFIGURATION (SURFACE AREA, VOLUME,
EMBANKMENT, OUTLET PIPE WITH ANTI -SEEP COLLAR, OUTLET CONTROLLED STRUCTURE WITH ANTI -FLOATATION ANCHOR,
SPILLWAY, ETC). DON'T INSTALL PERMANENT ORIFICES AT THIS POINT, ONLY INSTALL REQUIRED OPENING TO ATTACH
TEMPORARY SKIMMER HANDLE.
6. CALL FOR ON -SITE INSPECTION BY EROSION CONTROL INSPECTOR. WHEN APPROVED, INSPECTOR ISSUES THE GRADING PERMIT
AND CLEARING AND GRUBBING MAY BEGIN.
7. FOR PHASED EROSION CONTROL PLANS, CONTRACTOR SHALL MEET WITH EROSION CONTROL INSPECTOR PRIOR TO
COMMENCING WITH EACH PHASE OF EROSION CONTROL MEASURES. SEE PLAN THIS SHEET FOR DELINEATION OF ANTICIPATED
CONSTRUCTION PHASES CLEARING LIMITS TO CORRESPOND TO CRITICAL AREA CRITERIA.
- REFER TO "ENHANCED EROSION CONTROL CHECKLIST" THIS SHEET FOR ALL APPLICABLE REQUIREMENTS IN LAKE WYLIE
WATERSHED OVERLAY (REGULATED DRINKING WATER) PROTECTED AREA.
