PAVING NOTES
AND DETAILS
PAVING NOTES
1.THE CONTRACTOR IS REQUIRED TO SUBMIT A DETAILED PAVING PLAN REFLECTING PROPOSED LIFT
THICKNESS, TRANSVERSE JOINT LAYOUTS, AND LONGITUDINAL JOINT LAYOUTS, A MINIMUM OF 30 DAYS
PRIOR TO PAVING. THE CONTRACTOR SHALL ATTEND A PRE-PAVING CONFERENCE CONDUCTED BY THE
ENGINEER PRIOR TO THE START OF PAVING OPERATIONS. THE PAVING FOREMAN SHALL BE PRESENT
AT THE CONFERENCE. THE CONTRACTOR SHALL BE PREPARED TO DISCUSS HIS PROPOSED
LAYDOWN/PAVING PLAN
2.THE CONTRACTOR SHALL PAVE TO ELEVATIONS PROVIDED ON THE PAVING PLAN, SEE SHEET C-09 TO
ENSURE FULL COMPLIANCE.
3.TACK COAT SHALL BE APPLIED BETWEEN EACH LIFT OF NCDOT 9.5B, AS DESCRIBED IN NCDOT 605..
4.LONGITUDINAL JOINTS WHICH ARE IRREGULAR, DAMAGED, UNCOMPACTED, OR OTHERWISE DEFECTIVE
OR WHICH HAVE BEEN EXPOSED FOR MORE THAN 4 HOURS, OR WHOSE SURFACE TEMPERATURE HAS
COOLED TO LESS THAN 160° F SHALL BE CUT BACK NO MORE THAN 12 INCHES TO EXPOSE A CLEAN,
SOUND SURFACE FOR THE FULL DEPTH OF THE COURSE. THE LONGITUDINAL JOINT SHALL BE SAWCUT
IF ANY, ALL, OR SOME COMBINATION(S) OF THE ABOVE CONDITIONS ARE PRESENT. ALL CONTACT
SURFACES SHALL BE CLEANED AND DRY PRIOR AND GIVEN A TACK COAT OF BITUMINOUS MATERIAL
PRIOR TO PLACING ANY FRESH MIXTURE AGAINST THE JOINT. THE COST OF THIS WORK AND TACK COAT
SHALL BE CONSIDERED INCIDENTAL TO THE COST OF THE BITUMINOUS COURSE.
5.25' PAVERS WILL NOT BE ALLOWED. A JOINT WILL BE CONSIDERED "COLD" IF MORE THAN THIRTY
MINUTES ELAPSE BETWEEN PAVING. TRANSVERSE JOINT SHALL BE MINIMIZED BY THE CONTRACTOR.
6.CONTRACTOR IS RESPONSIBLE FOR MAINTAINING VERTICAL AND HORIZONTAL CONTROL FOR THE
PROJECT.
7.THE CONTRACTOR SHALL FIELD VERIFY TIE-IN LOCATIONS PRIOR TO PAVING OPERATIONS.
8.CONTRACTOR SHALL ENSURE POSITIVE DRAINAGE SO THAT RUNOFF WILL DRAIN BY OVERLAND SHEET

DRAINAGE AREA
GENERAL STORMWATER NARRATIVE
THE PROPOSED PROJECT IS WITHIN THE DRAINAGE AREA LIMITS "PHASE I AND PHASE II" OF
STORMWATER PERMIT SW8 050547. THE DRAINAGE AREA OUTFALLS TO AN EXISTING EXTENDED
DRY DETENTION BASIN ON THE SOUTH SIDE OF WILMINGTON INTERNATIONAL AIRPORT. THE
TOTAL DRAINAGE AREA OF PHASE I AND PHASE II IS 287.63 ACRES. AS PER THE MOST CURRENT
SW8 050547 PERMIT MODIFICATION DATED 03/23/2023, THE EXTENDED DRY DETENTION BASIN
HAS AN APPROVED ALLOWABLE IMPERVIOUS AREA OF 8,520,835 SF.
THE PROPOSED PROJECT IS ALSO WITHIN THE LIMITS OF STORMWATER MASTER PERMIT SW8
040836. THE MASTER PERMIT IS TO MAINTAIN AN OVERALL LOW DENSITY FOR THE APPROXIMATE
1,621-ACRE AIRPORT TRACT. THE PERMIT ALLOWS NO MORE THAN 486.20 ACRES OF
BUILT-UPON-AREA (BUA). AS PER THE MOST CURRENT SW8 040836 PERMIT MODIFICATION DATED
OCTOBER 3, 2019, THERE IS APPROXIMATELY 303.858 ACRES OF EXISTING BUA ON THE AIRPORT
TRACT. CURRENTLY THIS LEAVES APPROXIMATELY 182.342 ACRES OF ALLOWABLE BUA FOR
FUTURE DEVELOPMENT. THIS PROJECT WILL PROPOSE A MODIFICATION TO BOTH STORMWATER
PERMIT SW8 050547 & MASTER PERMIT SW8 040836.
THE NEW PARKING LOT PROJECT OUTFALLS AND IS WITHIN THE DRAINAGE AREA LIMITS OF THE
SW8 050547. THE PROPOSED PARKING LOT HAS A TOTAL BUA OF 231,744 SF. THE PHASE I AND
PHASE II DRAINAGE AREA HAS AN EXISTING BUA OF 5,757,271 SF. A TOTAL BUA FOR THE
POST-CONDITION WILL BE 5,989,015 SF WHICH IS WITHIN THE ALLOWABLE PERMITTED FOR THE
EXISTING EXTENDED DRY DETENTION BASIN. A TABLE FOR BOTH PERMITS WITH DETAILED
CALCULATIONS HAS BEEN PROVIDED BELOW.
