Practice 6.06
Small be Installed at the entrances of the proposed
project In and from Albemarle and Sturbridge as shown. Drainage
Is away from the road and sedimentation will be controlled
with downstream practices. During wet weather it may be
necessary to wash: truck tires at these locations.
2. LAND GRADING
Practice 6.02
Grading should be limited to areas as shown on the Plans.
Cut and fill stapes shall be 3:1 or hatter except where
spea"liy indicated. Care shall be taken:: during land
grading activities not to damage existing trees that are
not required to be removed.
3. SEDIMENT FENCE
Practice 6.62
Sediment fencing should be Installed as shown on the Plan,
first, to delineate and protect low areas, and around any
X °-", X,-,,,,X temporary stockpile areas as necessary to prevent any graded
interior areas from eroding onto adjacent lands or roadway. or

S. CONSTRUCTION ROAD STABILIZATION
Prance 6.80
Upon reaching final grade and after utilities have been
Installed; roadways and parking areas are to be stabilized by
placing sub -rase course of approved 8" ABC stone, as shown In
the typical cmss-section detail on the Plan, to reduce
erosion and bust during the remainder of building Construction.'
CD 6. CHECK -DAM EM

STANDARD NOTES.
1. Informa€ion conceming underground utilities was obtained from
available records. it shall be the responsibility of the
Contractor to determine the exact elevations and locations
of all existing utilities at ail crossinngs prior to
commencing trench excavation. If actual clearances are less
than indicated on Plan, the Contractor shall contact the
Design Engineer before proceeding with construction.
Any condition discovered or existing that would necessitate
a modification of these Mans shall be brought to the attention
of the Design Engineer before proceeding with construction.
2. NO CONSTRUCT -ION IS TO BEGIN BEFORE LOCATION OF EXISTING
UTILITIES HAS BEEN DETERMINED. CALL INC ONE-CALL"AT LEAST
48 HOURS BEFORE COMMENCING CONSTRUCTION.
3. All frees which are not required to be cleared for
construction shall be preserved wherever passible unless
otherwise directed.
4. Contractor shall adjust all manholes, valve and curb boxes to
the final grade upon completion of all construction. Any boxes
damaged or otherwise disturbed by the Contractor shall be
repaired at the expense of the Contractor.
5. The Contractor is responsible for controlling dust and erosion
during construction at his expense. Parking areas shall be
watered to control dust when ordered by the Engineer.

warranty is made for suitability of subgrade, and undercut and
any required replacement with suitable material shall be the
responsibility of the contractor.
Contractor responsible for geotechnir,,al testing as necessary.
7. Extreme care shaft be to ensure minimum separations at
all utility crossings.
8. Contractor to ensure that pavement Is placed so as to drain
positively #o the Curb r�utlets and catch basins. All roof
drain downspouts to be directed to the storm sewer system.
9 Contractor is responsible' for ob#alning all required permits,
10. This plan is for site utilities, grading, roadwork, and drainage only.
11. Affected Non Municipal Utilities shall be contacted and provided
with plans and other pertinent information, when feasible, to
coordinate appropriate scheduling and placement. At the minimum
this should include AT&T and Progress Energy.
12. Contractor and Builder are responsible for coordinating Finished
Floor Elevation of all buildings with the Owner and the Architect.
73. No encumberances to R!W except as shown.
MORE GENERAL NOTir...Ss
1. ALL CONSTRUCTION TO CONFORM TO NEW HANOVER COUNTY STANDARDS
AND APPLICABLE STATE & LOCAL CODES,
2. CONTRACTOR TO COORDINATE ANY REQUIRED TRAFFIC CONTROL WITH
NCDOT AND CAPE FEAR PUBLIC UTILITYAUTHORITY,
3. CARE SHALL BE TAKEN DURING FINAL GRADING TO ENSURE POSITIVE
DRAINAGE AWAY FROM BUILDINGS AND TO RECEIVING STRUCTURES.
4. CONTRACTOR IS RESPONSIBLE FOR COORDINATION OF ANY RELOCATIONS,
RE -ALIGNMENTS, DISCONNECTIONS OR CONNECTIONS OF EXISTING
UTILITIES WITH APPLICABLE AUTHORITIES.
5 CLEARING AND GRUBBING OF SITE TO INCLUDE REMOVAL OF EXISTING
CURB, ASPHALT, INLETS, AND ANY OTHER STRUCTURES INCLUDING TREES,
STUMPS AND DEBRIS EXISTING ON SITE. TREES NOT REQUIRED TO BE
CLEARED FOR CONSTRUCTION SHALL REMAIN UNLESS OTHERWISE DIRECTED.
S. MINIMUM SEPARATION SHALL BE MAINTAINED AS FOLLOWS:
a. HORIZONTAL CLEARANCE OF 10 FEET BETWEEN SANITARY SEWER AND
WATER MAINS.
b. WHERE VERTICAL CLEARANCE IS LESS THAN 18" BETWEEN SANITARY
SEWER AND WATER OR WHERE SEWER LINE CROSSES ABOVE WATER
MAIN, BOTH PIPES SHALL BE DUCTILE IRON PIPE FOR A MINIMUM
OF 10' EITHER SIRE OF CROSSING,
c. WHERE VERTICAL CLEARANCE IS LESS THAN 24" BETWEEN SANITARY
SEWER AND STORM DRAIN, SANITARY SEWER SHALL BE DUCTILE IRON
PIPE FOR A MINIMUM OF 10' EITHER SIDE OF CROSSING,
d. WHERE VERTICAL CLEARANCE IS LESS THAN 18" BETWEEN WATER
MAIN AND STORM DRAIN, WATER MAIN SHALL BE DUCTILE IRON
PIPE FOR A MINIMUM OF 10' EITHER SIDE OF CROSSING.

3. Install Gravel Construction En"nws.
4, Install Silt Fencing as shown on Plan ptlor to clearing and
gtubbtng situ. Sediment Basin to be constructed prior to buiidirrg.
5. Install utititles In roadway and drives, establish final grades and
stabilize parking areas and roadways with stone bass course.
6. Final grade building sites. Install non -municipal utEEltles as
needed, and vegetatively stabilize areas whets building
construction Is not Imminent.
7. All eroslon and sediment control Practices are to be Inspected
weekly and alter any rainfall, and repaired as necessary.
S. Upon completion of building Construction, the roadway and
parking areas are to be paved and all areas permanently
vegetatively stabilted, After site stabilization, temporary
measures are to be removed and the Sediment Basin cleaned to
Its original design contours, If necessary. and riser
structures orifaces opened, so as to function as a stormwater
management 1 water quality retention pond.
MAINTENANCE PLAN -
1. All measures to be Inspected woft and after any rainfall
event and treaded repairs made Immediately.
2. Sediment Basin to be cleaned out when the level of sediment
reaches as shown on individual pond plans.
3. Construction entrance to be mWntatned In a condition to prevent
mend or sediment from leaving the construction site. Periodic
topdressing with 2!eton+er may be required. Remove all objectionable
material spilled, washed, of Itacdced onto public roadways lmrnedlatety.
4. Sediment to be removed from behind the any Slit Fence and
Inlet protection devices when it becomes 0.6 deep. Fencing
and Inlet protection to be repaired as needed to maintain a
barrier.
S. All seeded areas shall be fertilized, mulched, and re-sooded
as necessary, according to spedficatfons provided, to
maintain a sultablo vegetative cover.
6. Inspect rtp-rap outlet structures weokly and after significant (112 Inch
or greater) rainfall events to see if any erosion around or below rip -rap
has taken place, or if stones have been dislodged. immediately make
all nestled repairs to prevent further damage.
7. Inspect baffles at least once a week and after each rainfall. Matte any
required repairs immediately.
8, Skimmer to be Inspected weekly and after each stgnficant rain event
(1I2 inch or greater) and repaired Immediately. Make sure that the
skimmer does not become entangled In basin vegetation or trapped in
slit due to low water conditions.

l a ferti i Izer at: .700-1. 000 lb. /acre, Both ferti t izer and
time should be incorporated into the top 4-6 inches of soft. If a hydraulic
seeder is used, do notmix seed and fert;tIzer more than 30 minutes before
application
Surface roughening- If recent tillage operations have resulted Ina Loose ,
surface, additional roughening may not be required except to break up large
clods. If rainfall causes the surface 'to become seated or crusted, too.5en it
g by disking, raking, ang able methods,
Groove or furrow slopes steeper than 3; I on the contour before seeding CPr4ctice
603, Surface Roughening).

Plant Selection
Select on appropriate species or species mixture from Table 6. 10a, for seeding
al l or summer, and Table 6. 10c for
fat t.
Seeding I
Evenly apply seed using a cyclone seeder (broadcast),, &I It, cultipckckep seeder,
Or hydroseeder. Use seeding rates given in Table 6. 10a-6. loc. Broadcast Seeding
and hyroseedingareapproprmte for steep slopes whoreequipment cannotbe

be covered by raking or chain dragging, *nd then tightly firmed with 4 rotter, or
