SEEDING SPECIFICATIONS:
SURFACE STABILIZATION MEASURES WILL BE COMPLETED IMMEDIATELY FOLLOWING SITE RECLAMATION AND PRIOR TO PROJECT
COMPLETION. TEMPORARY OR INTERMEDIATE SEEDING, MULCHING, MATTING, OR OTHER SURFACE STABILIZATION MEASURES WILL
BE PLACED ON DISTURBED AREAS FOLLOWING INITIAL SOIL DISTURBANCE. PRIOR TO SEEDING, ALL SURFACES SHALL BE SCARIFIED
TO A DEPTH OF FOUR TO SIX INCHES TO ENHANCE SEED GERMINATION AND HELP IMPEDE STORMWATER RUNOFF. SEEDING
MIXTURES WILL BE TAILORED TO SITE - SPECIFIC CONDITIONS, STEEPNESS OF SLOPES, CLIMATE, LOCATION, AND ELEVATION.
TYPICAL SEEDING GUIDELINES ARE AS FOLLOWS:
CREEPING RED FESCUE 75 LB /ACRE
RED CLOVER 50 LB /ACRE
RYE GRAIN 40 LB /ACRE
IN THE ABSENCE OF SOIL TESTS, FERTILIZER AND LIME WILL GENERALLY BE APPLIED AT THE FOLLOWING RATES:
10 -10 -10 FERTILIZER 500 LB /ACRE
GROUND AGRICULTURAL LIMESTONE 2000 LB /ACRE
LIQUID LIME OR ALTERNATIVE FERTILIZERS MAY BE SUBSTITUTED IN VARIOUS SITUATIONS.
MULCH OR MATTING SHALL BE APPLIED TO ALL SEEDED AREAS TO AID IN THE ESTABLISHMENT OF VEGETATION AND HELP IMPEDE
EROSION. VEGETATIVE MULCH, TYPICALLY WHEAT OR OAT STRAW, SHALL BE APPLIED AT THE RATE OF 3,000 TO 4,000 LBS /ACRE.
NOTE: PROVISIONS SHALL INCLUDE TEMPORARY OR PERMANENT STABILIZATION (WITH GROUND COVER) OF ALL
PERIMETER DIKES, SWALES, DITCHES, AND PERIMETER SLOPES STEEPER THAN 3:1 (HORIZONTAL TO VERTICAL) WITHIN 7
DAYS FOLLOWING THE LAST LAND - DISTURBING ACTIVITY. ALL OTHER DISTURBED AREAS SHALL BE PROVIDED
TEMPORARY OR PERMANENT STABILIZATION (WITH GROUND COVER) WITHIN 14 DAYS FOLLOWING THE LAST
LAND - DISTURBING ACTIVITY.
PROPOSED CONSTRUCTION SEQUENCE:
1. OBTAIN SEDIMENT AND EROSION CONTROL PERMIT FROM NC DENR. NOTE: IMPORT FILL WILL BE REQUIRED TO CONSTRUCT
THE SUBSTATION AND RECYCLING CENTER FACILITIES. HOWEVER, A BORROW SITE HAS NOT YET BEEN ACQUIRED. ONCE THE
BORROW SITE HAS BEEN IDENTIFIED, A REVISE SEDIMENT AND EROSION CONTROL PLAN SHALL BE SUBMITTED TO NC DENR
FOR APPROVAL.
2. INSTALL CONSTRUCTION ENTRANCE FOR ACCESS TO THE SITE.

SWALE MUST BE CONSTRUCTED ENTIRELY IN "DRY" CONDITIONS BEFORE RE- CHANNELLING STORMWATER FLOW FROM THE
EXISTING DRAINAGE SWALE.
4. INSTALL ACCESS DRIVE CULVERT AND ASSOCIATED EROSION CONTROL MEASURES. UPON COMPLETION, STORMWATER FLOW
MAY BE RE- DIRECTED FROM THE EXISTING SWALE /CHANNELTO NEW RIP RAP CHANNEL. OLD STORMWATER SWALE
SHALL BE REMOVED (FILLED) AT THIS POINT.
5. INSTALL EROSION CONTROL MEASURES AT THE INLET OF NEW CULVERT AND BEGIN CONSTRUCTION OF THE DIVERSION
SWALE ALONG THE SOUTHERN PERIMETER OF THE CONSTRUCTION SITE.
6. COMPLETE GRADING OF THE DIVERSION SWALE, AND FERTILIZE, SEED AND MAT (WITH EROSION CONTROL FABRIC) THE SWALE
AS SOON AS POSSIBLE. NOTE: THE INTENT IS TO CAPTURE ALL STORMWATER FLOW UPSLOPE FROM THE CONSTRUCTION SITE
(FROM GOLF COURSE AREA) AND DIRECT IT THROUGH THE CONSTRUCTION SITE CLEANLY VIA THE NEW CULVERT, RIP RAP
7 CHANNEL AND DIVERSION SWALE.
8. INSTALL REMAINING EROSION CONTROL MEASURES FOR GRADING /SITE DEVELOPMENT OF THE SUBSTATION PAD AND
RECYCLING CENTER LOT.
9. CLEAR AND GRUB THE SUBSTATION PAD AND THE RECYCLING CENTER LOT.
10. INSTALL SUB - SURFACE SYSTEM /SYSTEMS (AS NEEDED) FOR POSSIBLE SEEPAGE FROM SPRING HEADS.
11. BEGIN CONSTRUCTION OF THE SUBSTATION RETAINING WALL AND FILL OPERATIONS FOR CONSTRUCTION OF THE SUBSTATION
AND RECYCLING CENTER PADS.
12. COMPLETE RETAINING WALL AND SUBSTATION /RECYCLING CENTER GRADING.
13. COMPLETE CONSTRUCTION OF SUBSTATION ACCESS DRIVE (GRAVEL PAVING).
14. FERTILIZE, SEED AND MULCH ALL DISTURBED AREAS.
15. CONSTRUCT RECYCLING CENTER AMMENITIES (CONCRETE PAD FOR DUMPSTERS AND ACCESS DRIVE).

CONSTRUCTION, AND NOTIFY THE ENGINEER IMMEDIATELY IF ANY DISCREPANCIES EXIST BETWEEN THE
CONSTRUCTION PLANS AND ACTUAL FIELD CONDITIONS.
3. IN GENERAL, MAXIMUM SLOPES SHALL BE 2:1 FOR CUT SLOPES AND 3:1 FOR FILL SLOPES, UNLESS OTHERWISE
NOTED.
4. THE CONTRACTOR SHALL CLEAR /GRUB ALL VEGETATION, TOPSOIL, ORGANIC MATERIALS, ROCKS, AND OTHER

DISPOSAL OF ALL CLEARED DEBRIS AND UNDERCUT MATERIAL SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR.
ALL SPOIL /WASTE MATERIALS SHALL BE DISPOSED OF IN A MANNER AS TO MEET ALL
MUNICIPAL /COUNTY /STATE /FEDERAL REGULATIONS.
5. IMPORT FILL WILL BE REQUIRED FOR GRADING /CONSTRUCTION OF THE SITE. IT SHALL BE THE RESPONSIBILITY OF
THE CONTRACTOR TO LOCATE A BORROW SITE WITH ADEQUATE FILL MATERIAL THAT MEETS THE REQUIREMENTS
FOR CONSTRUCTION OF THE FACILITY PADS AND THE ASSOCIATED RETAINING WALL. IT SHALL BE THE
RESPONSIBILITY OF THE CONTRACTOR TO PROVIDE "QUALIFYING" SOIL TESTING.
6. THE CONTRACTOR SHALL BE RESPONSIBLE FOR ALL SURVEYING SUPPORT FOR CONSTRUCTION /PLACEMENT OF FILL
MATERIAL. HE SHALL PROTECT REFERENCE BENCHMARKS AND SURVEY CONTROL POINTS FROM EXCAVATING AND
VEHICULAR TRAFFIC, AND DAMAGE.
7. THE CONTRACTOR SHALL BE RESPONSIBLE FOR THE INSTALLATION OF ALL INDICATED SEDIMENT AND EROSION
CONTROL MEASURES, AND THE MAINTENANCE OF SUCH UNTIL SITE STABILIZATION HAS BEEN ACHIEVED. DURING

SEDIMENT RUNOFF. ANY /ALL PROBLEMS SHALL BE BROUGHT TO THE ATTENTION OF THE ENGINEER.
8. The Contractor shall BE RESPONSIBLE FOR OBTAINING /TRANSPORTING /PLACEMENT OF ALL IMPORT FILL NECESSARY
TO GRADE /CONSTRUCT the substation AND RECYCLING CENTER FACILITIES TO THE INDICATED ELEVATIONS and
contours. NOTE: INDICATED ELEVATIONS REFLECT "FINISHED GRADE" ELEVATIONS FOR GRADING /SITE
DEVELOPMENT. THE RECYCLING CENTER SHALL BE GRAVEL PAVED UPON COMPLETION (6" COMPACTED "ABC
STONE), THUS, THE CONTRACTOR MUST DEDUCT FILL MATERIAL FOR SUCH GRAVELLING.

13. UPON COMPLETION OF SITE GRADING ACTITIES, THE RETAINING WALL SHALL BE COMPLETE AND THE SUBSTATION
PAD SHALL BE GRADED SMOOTH, COMPACTED AND SLOPED TO PREVENT WATER PONDING.
14. THE CONTRACTOR SHALL SUSPEND GRADING OPERATIONS WHEN CLIMATIC CONDITIONS DO NOT ALLOW FOR WORK
TO BE PERFORMED SAFELY, PREVENT ADEQUATE PLACEMENT /COMPLACEMENT OF SOIL, OR IF CONTINUED WORK
CAUSES SITE DAMAGE. ALL WEATHER EXCEPTIONS SHALL BE DOCUMENTED BY THE CONTRACTOR.

SEED -BED SUPPORT.
16. IT SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR AT ALL TIMES TO HELP PREVENT EROSIVE CONDITIONS AND
OFF -SITE SEDIMENTATION FROM DEVELOPING ON THE CONSTRUCTION SITE. THE CONTRACTOR SHALL INSTALL ALL
SEDIMENT AND EROSION CONTROL MEASURES PER THE CONSTRUCTION PLANS AND MAINTAIN THESE MEASURES
THROUGHOUT PROJECT CONSTRUCTION AND STABILIZATION. ADDITIONAL MEASURES COULD BE NEEDED TO HELP

ENGINEER FOR ASSISTANCE.
17. WHILE "ON SITE ", THE CONTRACTOR SHALL PERFORM ANY /ALL SITE INSPECTIONS FOR THE SITE, PER LOCAL, STATE
AND /OR FEDERAL REGULATIONS.
18. ALL SEDIMENT AND EROSION CONTROL MEASURES SHALL BE INSPECTED AT LEAST ONCE EVERY 7 DAYS AND WITHIN
24 HOURS AFTER ANY SIGNIFICANT RAINFALL EVENT (1/2" OR GREATER). FAILURE TO INSTALL OR MAINTAIN
EROSION CONTROL MEASURES MAY RESULT IN ALL CONSTRUCTION BEING STOPPED ON THE JOB UNTIL SUCH
MEASURES ARE CORRECTED TO REQUIRED STANDARDS.
19. IT SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR TO REMOVE ALL SEDIMENT AND EROSION CONTROL
MEASURES AFTER SITE STABILIZATION HAS BEEN ACHIEVED.
20. THE CONTRACTOR SHALL BE RESPONSILE FOR THE GRAVELLING OF THE ACCESS ROAD UP TO THE "WALLED'
