NARRATIVE
Oldwick Commons (JTC Highway 70 Property), Lot 1 is part of a new commercial/general
business office park development along US Highway 70 in Township 7, Craven County, North
Carolina (See Vicinity Map). The project is located on a 2.81 acre commercial/general business
lot in the Oldwick Commons development. This project will include stripping topsoil and debris
on the site, roadway construction, building construction, parking lot construction, drainage
feature construction, water main and sanitary sewer pressure main construction.
The Craven County Water Department will provide potable water service. The City of New Bern
will provide sanitary sewer.
The current use of the land is primarily logged woods and grassy open lands.
This project is a modification of Permit No. SW7070330, issued on May 2, 2007.
All stormwater runoff from the impervious areas of the site for Lot 1 will be drained to a wet
detention basin located on the lot. It was not permitted when the common wet detention basin
for Lots 2-6 and the new street were permitted because it is physically separated from the
remainder of the development by wetlands. The wet detention basins will serve as sediment
basins during construction and will require cleaning before being converted to wet detention
basins. The level of the permanent pool for the wet detention basin for Lot 1 was set at 21.50
feet MSL to relatively match the surface elevation of the adjacent wetlands. The design is
based on the surface elevation of the wetlands, not on the seasonal high water table so there
was not any subsurface soils information determined. Roadside ditches along the frontage road
will continue to function as they currently do. The outlet from the wet detention pond and the
outfall for the roadside ditches drain to the west, is piped under the railroad tracks and drains to
Brice Creek (Class C;Sw;NSW) and eventually to the Trent River (Class SB;Sw;NSW) and the
Neuse River (Class SC;Sw;NSW).
The outlet from the wet detention pond for Lot 1 drains to an existing ditch, therefore no level
spreader device will provided.
The total area of Lot 1 is approximately 2.81 acres. There are 0.49 acres of wetlands on Lot 1.
The allowable impervious area for Lot 1 is 1.11 acres or 47.9% of the total upland area for the
Lot.
One drainage basin has been identified for this site.
The predevelopment rate of runoff for Lot 1 is calculated as 0.79 cfs and the post -development
rate of runoff is calculated as 3.84 cfs. The post development rate of runoff will be attenuated
by the construction of the wet detention pond, which has a maximum drawdown rate of 0.028
cfs for the 1" rainfall event.
The predominant soil types obtained from soil survey maps, Craven County, North Carolina are:
GoA — Goldsboro loamy fine sand, 0 to 2 percent slopes
Le — Lenoir silt loam
Me — Meggett sandy loam
Oldwick Commons, Lot 1, Craven County, NC Page 2
October 29, 2007

Goldsboro loamy fine sand, 0 to 2 percent slopes is moderately well drained. The seasonal
high water table is 2 to 3 feet below the surface. The available water capacity is moderate,
permeability is moderate, and the shrink -swell potential is low.
Lenoir silt loam soil is somewhat poorly drained. The seasonal high water table is 1.0 to 2.0 feet
below the surface. The available water capacity is high, permeability is slow, and the shrink -
swell potential is moderate.
Meggett sandy loam is poorly drained. The seasonal high water table is at or near the surface.
The available water capacity is high, permeability is slow, and the shrink -swell potential is high.

3.5 TEMPORARY MULCHING
A. Temporary mulch may be used for the prevention of excessive soil erosion during construction
operations where it is impossible or impractical to perform permanent seeding and mulching.
B. Temporary much shall be placed promptly at the location and times directed by the Engineer.
C. The temporary mulch may be required on previously seeded areas or on areas which have not
been seeded.
D. Temporary mulches may be straw, fiber mats, netting or other suitable material acceptable to the
Engineer and shall be reasonably clean and free of noxious weeds and deleterious material.
Mulch shall be spread uniformly over the area by hand or by means of approximate mechanical
spreaders or blowers to obtain an application satisfactory to the Engineer. On seeded areas,
satisfactory application of temporary mulch shall allow some sunlight to penetrate and air to
circulate, but also partially shade the ground, reduce erosion and conserve soil moisture-
E. When temporary mulching is being performed in connection with temporary seeding, no seeded
areas shall be allowed to remain more than 24 hours without mulching having been completed.
F. If seeding has been performed previously, care shall be exercised to prevent displacement of soil
or seed, or other damage to the seeded area during temporary mulching operations.
i
G. The Contractor shall take sufficient precautions to prevent temporary mulch from entering pipe
lines and drainage structures through displacement by wind, water or other causes.
H. The Contractor shall apply a sufficient amount of asphalt or other type material to assure that the
temporary mulch is properly held in place.
I. In the application of asphalt materials during temporary mulching operations, adequate
precautions shall be taken to'prevent damage to traffic; and to any private or public property.
Such property shall be adequately covered, or application methods changed, so as to avoid
damage. Where any damage occurs as a result of the Contractor's failure to take adequate
Oldwick Commons, Lot 1, Craven County, NC Page 10
October 29, 2007

precautions, the Contractor will be required to repair such damage, including any cleaning that
may be necessary, before final acceptance of the work will be made.
3.6 REPAIR SEEDING & MAINTENANCE
A. Maintain the grass on the areas for a period of 90 days after the grass growth appears. Reseed
bare areas and repair all eroded areas during that period.
B. Inspect all seeded areas and make necessary repairs or reseedings within the planting season, if
possible. If stand should be over 60% damaged, reestablish following original lime, fertilizer and
seeding recommendations.
C. All areas which do not exhibit satisfactory ground cover within 45 days of seed application shall
be replanted.
D. Repair seeding shall be performed in accordance with the requirements of Section 1661 of the
North Carolina State Department of Transportation's Standard Specifications for Roads and
Structures, latest revision.
E. The kinds of seed and fertilizer shall be the same as specified for permanent "seeding and
mulching". The rates of application of the various kinds of seed specified for "seeding and
mulching" may vary as directed by the Engineer, however the total rate shall be substantially the
same as for "seeding and mulching", but in no case will the total rate of seed and fertilizer vary
more or less than twenty-five (25%) percent of that specified for "seeding and mulching".
3.7 SUPPLEMENTAL SEEDING
A. The work covered by this section consists of the application of additional seed to an area already
seeded with permanent seed but on which there is not a satisfactory cover of grass.
B. The work of supplemental seeding does not include seedbed preparation, fertilizer, limestone, or
mulch, and is intended only to provide an additional amount of seed to the Fertilizer Top dressing
operation on projects that do not have a stand of grass thick enough to cover the ground in a
reasonable length of time. This work does not conflict with nor replace repair seeding as its
purpose is entirely different.
C. The kinds of seed shall be the same as for "seeding and mulching", and the rate of application
may vary from 25 pounds to 75 pounds per acre. The final rate per acre; if needed, will be
determined by the Engineer prior to the time of top dressing and the Contractor will be notified in
writing of the rate per acre, total quantity needed and areas on which to apply the supplemental
seed.
3.8 FERTILIZER TOP DRESSING:
A. Fertilizer top dressing shall be performed in accordance with the requirements of Section 1665 of
the North Carolina State Department of Transportation's Standard Specifications for Roads and
Structures, latest revision.
3.9 WETLAND PLANTING:
A. Wetland planting regions shall be as follows:
1. Upland
a. This area shall be stabilized with a warm season grass from the permanent and
temporary seeding schedules of this specification and straw or jute matting. Additional
erosion control measure may be required depending on the phasing of construction.
