ELECTRIC UTILITY POLES AS REQUIRED FOR THE EXCAVATION.
5. REGULATIONS AND CODES, SHALL BE CONSISTENT WITH NCDOT, NCDER
REQUIREMENTS AND STATE BUILDING CODE.
6. RELATION OF WATER MAINS TO SEWERS
(a) LATERAL SEPARATION OF SEWERS AND WATER MAINS. WATER MAINS SHALL BE
LAID AT LEAST 10 FEET LATERALLY FROM EXISTING OR PROPOSED SEWERS,
UNLESS LOCAL CONDITIONS OR BARRIERS PREVENT A 10-FOOT LATERAL
SEPARATION-- IN WHICH CASE: (1) THAT WATER MAIN IS LAID IN A SEPARATE
TRENCH, WITH THE ELEVATION OF THE BOTTOM OF THE WATER MAIN AT LEAST
18 INCHES ABOVE THE TOP OF THE SEWER; OR DENR-PUBLIC WATER SUPPLY
SECTION 15A: 18C.0900 (2) THE WATER MAIN IS LAID IN THE SAME TRENCH AS
THE SEWER WITH THE WATER MAIN LOCATED AT ONE SIDE ON A BENCH OF
UNDISTURBED EARTH, AND WITH THE ELEVATION OF THE BOTTOM OF THE
WATER MAIN AT LEAST 18 INCHES ABOVE THE TOP OF THE SEWER.
SEEDBED PREPARATION (SP)
SP-1 Fill slopes 3:1 or steeper to be seeded with a hydraulic seeder
(permanent seeding).
1) Leave the last 4-6 inches of fill loose and uncompacted, allowing
rocks, roots, large clods and other debris to remain on the slope.
2) Roughen slope faces by making grooves 2-3 inches deep,
perpendicular to the slope.
3) Spread lime evenly over slopes at rates recommended by soil
tests.
SP-2 Fill slopes 3:1 or steeper (temporary seedings).
1) Leave a loose, uncompacted surface. Remove large clods, rocks,
and debris which might hold netting above the surface. 2) Spread
lime and fertilizer evenly at rates recommended by soil tests.
3) Break up large clods and rake into a loose, uniform seedbed.
4) Rake to loosen surface just prior to applying seed.
SP-4 Gentle or flat slopes where topsoil is not used (grassed ditches)
1) Remove rocks and debris.
2) Apply lime and fertilizer at rates recommended by soil tests;
spread evenly and incorporate into the top 6" with a disk, chisel
plow, or rotary tiller.
3) Break up large clods and rake into a loose, uniform seedbed.
4) Rake to loosen surface just prior to applying seed.
SEEDING METHODS (SM)
SM-1 Fill slopes steeper than 3:1 (permanent seeding).
Use hydraulic seeding equipment to apply seed and fertilizer, a
wood fiber mulch at 45 Ib./1,000 s.f., and mulch tockifer.
SM-2 Gentle to flat slopes or temporary seedings.
1) Broadcast seed at the recommended rate with a cyclone
seeder, drop spreader, or cultipacker seeder.
2) Rake seed into the soil and lightly pack to establish good
contact.

NC Department of Transportation Permanent Seeding
Specifications
Permanent erosion control shall be performed as follows:
(a) All disturbed areas will be dressed to typical sections and plowed
to a depth of 5 inches. The top 2 inches shall be pulverized
to provide a uniform seed.
NOTE: Lime should be applied before plowing.
(b) Lime, seed, and fertilizer shall be applied with necessary
equipment to give uniform distribution of these materials. The
hand -bucket method is not acceptable. The following are rates
and kinds of these materials to be applied per acre:
75 lbs. Ky 31 Fescue
50 lbs. Pensacola Bahiagross
50 lbs. Korean Lespedezo
40 lbs. Sericea
500 lbs. 5-10-10 Fertilizer
4,000 lbs. Agricultural Limestone
NOTE: Only tested and certified seed shall be used. Seed certification
shall be provided to the District Engineer prior to use.
(c) Seeded area shall be cultipacked to firm seedbed and cover seed.
(d) Grain straw shall be applied over seeded areas as a mulch. No
bare ground shall be visible when riding by a mulched area if
proper application is achieved. Thick clumps of straw are not
permissible, as uniform coverage is expected.
(e) Mulched area shall be tacked with asphalt sufficient to hold straw
in place.
(f) Ditch treatment shall be used in areas where steep grades (more
than 10%) could cause ditch erosion. Use of jute mesh,
excelsior matting, or fiberglass roving is acceptable. Ditch
