GRADING & DRAINAGE GENERAL NOTES
1. ALL CONSTRUCTION SHALL COMPLY WITH ALL APPLICABLE STATE & LOCAL CODES,
AND OSHA STANDARDS.
2. THE CONTRACTOR SHALL NOT COMMENCE WITH LAND DISTURBANCE UNTIL
PERIMETER EROSION CONTROL DEVICES ARE INSTALLED. REFER TO EROSION
CONTROL DRAWINGS AND SPECIFICATIONS. FOLLOW EROSION CONTROL PLAN
DURING SEQUENCE OF GRADING AND ADD/ADJUST EROSION CONTROL MEASURES AS
NECESSARY TO CONTROL SEDIMENT AND EROSION.
3. COORDINATE THE PROJECT SCHEDULE WITH THE NATIONAL GUARD (OWNER), SMITH
SINNETT (ARCHITECT), TIMMONS GROUP (CIVIL ENGINEER), AND ADJACENT USERS OF
THE PROPERTY. MAINTAIN TRAFFIC FLOW AND DO NOT INTERRUPT UTILITIES AROUND
THE SITE. DO NO DISTURB OPERATIONS OF ONSITE AND ADJACENT FACILITIES.
4. OBTAIN OWNERS WRITTEN APPROVAL FOR ANY REQUESTED SHORT-TERM, OFF -HOUR,
OR TEMPORARY UTILITY SHUT- DOWNS OR DISRUPTIONS.
5. DISPOSE OFF -SITE WASTE MATERIALS GENERATED DURING CONSTRUCTION AND FOR
OBTAINING ALL APPLICABLE PERMITS FOR OFF -SITE STOCKPILES AND/OR WASTE
AREAS. IF THE SAME PERSON CONDUCTS THE LAND -DISTURBING ACTIVITY AND ANY
RELATED BORROW OR WASTE ACTIVITY, THE RELATED BORROW OR WASTE ACTIVITY
IS PART OF THE LAND DISTURBING ACTIVITY. IF THE BORROW OR WASTE ACTIVITY
ARE NOT CONDUCTED BY THE SAME PERSON, THEY SHALL BE CONSIDERED
SEPARATE LAND DISTURBING ACTIVITY AND MUST BE PERMITTED THROUGH THE
SEDIMENT POLLUTION CONTROL ACT.
6. SEE GENERAL NOTES ON EXISTING CONDITIONS AND DEMOLITION PLAN FOR
REQUIREMENTS FOR REMOVAL AND PATCHING OF PAVEMENT FOR UTILITY/STORM
INSTALLATION.
7. REPAIR OR REPLACE ANY ITEMS DAMAGED DUE TO CONSTRUCTION (ONSITE AND/OR
OFFSITE) AT NO EXPENSE TO THE OWNER.
8. MAINTAIN ALL EROSION CONTROL DEVICES AFTER EACH RAINFALL EVENT IN
ACCORDANCE WITH NCDEQ LAND QUALITY REQUIREMENTS AND AS DIRECTED BY THE
NCDEQ AND THE CIVIL ENGINEER.
9. FLUSH ALL SEDIMENT OUT OF STORM DRAINAGE PIPES AND STRUCTURES FOLLOWING
SITE STABILIZATION AND AT THE END OF CONSTRUCTION. FLUSH OUT PIPES AS
NEEDED THROUGHOUT CONSTRUCTION TO MAINTAIN PROPER FUNCTIONING OF THE
DRAINAGE SYSTEM.
10. IN DISTURBED AREAS, AMEND THE TOP 6 INCHES OF LAWN AREAS WITH 3 INCHES OF
IMPORTED AND TESTED TOPSOIL THAT MEET THE SPECIFICATIONS. SUBMIT
DOCUMENTATION ON THE PROPERTIES OF IMPORTED TOPSOIL FOR REVIEW. EXISTING
TOPSOIL MAY BE USED IF PROPERLY SCREENED AND AMENDED. REFER TO PLANTING
SPECIFICATIONS.
11. REMOVE ALL STONES, VEGETATION, AND DEBRIS LARGER THAN 1.5" WITHIN TOP 5" OF
FINISH GRADE SURFACE.
12. CONTACT OWNER AND CIVIL ENGINEER FOR AN INSPECTION OF FINISH GRADE AND
SLOPES PRIOR TO PERMANENT SEEDING. OWNER / CIVIL ENGINEER MUST APPROVE
FINISH GRADES PRIOR TO SEEDING.
13. ALL SIDEWALKS SHALL HAVE MAXIMUM CROSS SLOPE OF 2%.
14. INSTALL ALL STORM SEWERS TO PROVIDE REQUIRED CLEARANCES TO CROSSING
UTILITIES AS INDICATED IN THE DRAWINGS AND SPECIFICATIONS.
15. ALL PVC PIPING SHALL BE SCHEDULE 40 THICKNESS. USE DUCTILE IRON WHEN COVER
IS LESS THAN 24-IN. ADD ADAPTERS AS NECESSARY TO CONNECT SMALLER TO
LARGER PIPES.
16. INSTALL ADDITIONAL DRAINAGE SWALES IF DIRECTED BY THE CIVIL ENGINEER.
LOCALIZED DEPRESSIONS AT DROP INLETS SHALL EXCEED 10:1 SLOPE
17. PRIOR TO FINAL PROJECT ACCEPTANCE, PROVIDE AN AS -BUILT SURVEY OF ALL
UTILITY SYSTEMS, STORM SEWERS, AND THE STORM WATER CONTROL MEASURE
(WET POND).
18. EXISTING MANHOLES, VALVE BOXES, VAULTS, CLEANOUTS, UTILITY POLES ETC. TO
REMAIN WITHIN THE GRADING LIMITS SHALL BE ADJUSTED AS NEEDED TO FUNCTION
PROPERLY WITH THE PROPOSED FINISHED GRADES (WHETHER OR NOT INDICATED TO
BE MODIFIED).
