CONSTRUCTION SEQUENCE FOR WET DETENTION PONDS:
1. ENSURE ALL APPLICABLE PERMITS ARE ACQUIRED PRIOR TO ANY CONSTRUCTION ACTIVITIES.
2. WHEN PERMANENT WET DETENTION PONDS ARE TO BE USED AS SEDIMENT BASINS DURING
CONSTRUCTION, INSTALL BASIN TO PERMANENT POND DIMENSIONS AS SHOWN ON THE
APPROVED EROSION CONTROL PLAN.
3. DURING CONSTRUCTION, PROTECT STORM SEWER INLETS WITH INLET PROTECTION DEVICES,
SEDIMENT DEVICES, AND/OR OTHER APPROVED MEASURES. MAINTAIN DEVICES AS NEEDED.
4. AFTER COMPLETION OF ANY PHASE OF GRADING, ESTABLISH GROUNDCOVER ON GRADED
SLOPES AND FILLS WITHIN 15 CALENDAR DAYS.
5. STABILIZE SITE AS AREAS ARE BROUGHT UP TO FINISHED GRADE WITH VEGETATION OR PAVING.
6. CLEAN AND REMOVE SEDIMENT FROM POND AS NECESSARY DURING CONSTRUCTION.
7. WHEN CONSTRUCTION IS COMPLETE, REMOVE TEMPORARY DIVERSIONS, SILT FENCING,
SEDIMENT BASINS, ETC. AND PROVIDE ADEQUATE COVER OR PAVE ANY RESULTING BARE Alai AS.
8. COMPLETE CONVERSION TO PERMANENT WET DETENTION POND. CLEAN OUT ALL SEDIMENT, AND
ENSURE PERMANENT OUTLET STRUCTURE IS CONSTRUCTED PER THE APPROVED STORMWATER
MANAGEMENT PLAN. PERMANENT EROSION CONTROL DEVICES, SUCH AS VELOCITY
DISSIPATERS, SHOULD BE INSTALLED AT THIS TIME.

OVERALL STORM DRAINAGE
AND GRADING PLAN
PROJECT NOTES
1. ALL LAND DISTURBING ACTIVITIES SHALL BE CONDUCTED IN ACCORDANCE WITH THE CURRENT NASH COUNTY AND THE TOWN OF BAILEY
STANDARDS.
2. ALL TEMPORARY EROSION CONTROL MEASURES SHALL BE MAINTAINED IN PROPER WORKING CONDITION DURING THE PERIOD OF
CONSTRUCTION.
GRADING NOTES:
1. THE CONTRACTOR SHALL TOTALLY FAMILIARIZE HIMSELF WITH THE CONTRACT DOCUMENTS AND THE SITE AS WELL AS EXISTING CONDITIONS
AND THE DIFFICULTIES LIKELY TO BE ENCOUNTERED IN THE CONSTRUCTION OF THIS PROJECT.
2. THE CONTRACTOR SHALL MAKE EVERY EFFORT TO CONFINE DISTURBED AREAS TO A MINIMUM. ALL TREES AND OTHER VEGETATION SHALL
REMAIN UNLESS SHOWN OTHERWISE ON THE PLANS OR THEIR REMOVAL IS AUTHORIZED BY THE OWNER. ALL AREAS DISTURBED BY THE
CONTRACTOR DURING CONSTRUCTION SHALL BE SEEDED PER THE PROJECT SPECIFICATIONS.
3. THE CONTRACTOR SHALL ADEQUATELY PROTECT ALL TREES, PLANTS AND REFERENCE POINTS AS INDICATED ON THE PLANS AND AS DIRECTED BY
THE OWNER. TREE PROTECTION SHALL BE APPROVED BY THE OWNER OR THEIR REPRESENTATIVE AND SHALL BE IN ACCORDANCE WITH THE
PROJECT SPECIFICATIONS.
4. TO MINIMIZE DAMAGE TO EXISTING TREES NEAR THE INTERIOR EDGE OF BUFFERS AND STREETSCAPES, THE CONTRACTOR SHALL CUT MINIMUM 2
FOOT TRENCHES ALONG THE LIMITS OF DISTURBANCE, SO AS TO CUT, RATHER THAN TEAR ROOTS.
5. IF DISCREPANCIES DEVELOP BETWEEN THE PROPOSED GRADES AS SHOWN ON THE PLAN AND THE EXISTING GROUND SURFACE, THE
CONTRACTOR, WITH PRIOR APPROVAL OF THE OWNER, SHALL MAKE NECESSARY GRADING ADJUSTMENTS TO MAINTAIN THE GENERAL DESIGN
INTENT OF THE PLAN.
6. MODIFICATION OF GRADES: THE LANDSCAPE ARCHITECT SHALL HAVE THE RIGHT TO MODIFY GRADES SHOWN ON THE PLANS IN AREAS WHERE
MOUNDING HAS BEEN INCLUDED (I.E. BETWEEN BALL FIELDS & AT PROJECT ENTRANCES). CONTRACTOR IS TO EXPECT THESE FIELD CHANGES
WITHOUT ADDITIONAL COMPENSATION.
7. ALL CONSTRUCTION STAKING SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR UNLESS OTHERWISE SPECIFIED.
B. ALL SUBGRADES MUST BE PROOF ROLLED PRIOR TO PLACEMENT OF PAVEMENT.
9. ALL SPOT ELEVATIONS ARE TO TOP OF PAVEMENT OR FINISHED GRADE UNLESS OTHERWISE NOTED.
10. FILL MATERIALS SHALL BE PLACED ON LAYERS NOT MORE THAN 6 INCHES AND COMPACTED TO 100% STANDARD PROCTOR.
11. ALL A.D.A- PARKING SPACES SHALL HAVE A 2% MAX CROSS SLOPE.
12. ALL AREAS SHALL BE GRADED TO 0.1' OF THE PROPOSED GRADE SHOWN ON PLANS.
13. STABILIZATION IS THE BEST FORM OF EROSION CONTROL. TEMPORARY SEEDING 15 NECESSARY TO ACHIEVE CONTROL ON LARGE DENUDED
AREAS AND ESPECIALLY WHEN SPECIFICALLY REQUIRED AS PART OF THE CONSTRUCTION SEQUENCE SHOWN ON THE PLAN. ALL DISTURBED
AREAS MUST BE SEEDED AND MULCHED WITHIN 30 DAYS OF COMPLETION OF GRADING.
14_ THE CONTRACTOR IS TO ENSURE POSITIVE DRAINAGE IN ALL NEW SWALES.
15. ALL EROSION AND SEDIMENT CONTROL DEVICES WILL BE CHECKED FOR STABILITY AND PROPER OPERATION FOLLOWING EVERY RUN-OFF
PRODUCING RAINFALL. ANY NEEDED REPAIRS WILL BE MADE IMMEDIATELY BY THE CONTRACTOR TO MAINTAIN ALL PRACTICES AS DESIGNED.
PHASE 1 DENUDED AREA = 19.38 AC
PHASE 2 DENUDED AREA (NIC) = 16.27 AC (INCLUDES 2.88 AC OVERLAP)
TOTAL DENUDED AREA = 32.77 AC
STORMWATER BMP NOTES
I. TO MEET THE REQUIREMENTS OF THE NEUSE RIVER BASIN, STREAMS WITHIN THE SITE WILL BE SUBJECT TO 50' STREAM BUFFERS. IN ADDITION,
AN OVERALL STORMWATER MANAGEMENT PLAN IS PROPOSED THAT WILL TREAT THE RUNOFF FROM THE FIRST ONE INCH OF RAINFALL AND
REMOVE A MINIMUM OF EIGHTY-FIVE PERCENT (90%) OF TOTAL SUSPENDED SOLIDS (TSS). THIS WILL BE ACCOMPLISHED THROUGH THE USE OF
A WET DETENTION BASIN WITH A LEVEL SPREADER.
