before sheet Flowing to the sound.
6. The infiltration trench width is 30'. This has been corrected on the supplement sheet.
The height of the trench is 18" and the detail has been revised to show this.
7. The calculations for the trench volume have been included and the volume has been
added to the supplement sheet.
8. Page 4 has been initialed.
9. The length of the perforated pipe has been changed to 72W on the supplement sheet.
10. The appropriate infiltration units has been circled on the supplement sheet.
11. The benchmark for sediment removal has been added to the supplement sheet.
If there is any additional information needed or if you have any questions feel fi'ee to give n1e a

Fisheries Research Lab & Shop Building Replacement
Carteret County
Dear Ms. Suttenfield:
The Wilmington Regional Office received a Stormwater Management Permit Application for Fisheries
Research Lab & Shop Building Replacement on October 25, 2001. A preliminary review of that information
has determined that the application is not complete. The following information is needed to continue the
stormwater review:
Please label the inlet, outlet to flow box, and bypass pipes on the flow box detail. As shown, the
detail is confusing.
2. Please either delineate all wetlands on site, disturbed or undisturbed, or note on the plans that
none exist.
3. Please remove Weeping Love Grass from the seeding schedule. This grass is not recommended
for use in North Carolina as either a temporary or permanent grass cover.
4. What is the purpose of the 6 x 4 pit and the 12" CPP running from it out to the Sound? This
piping is labeled as the piping from the building trench grates, but the water collected in the
trench grate appears to be released on the west side of the building, not the back. Please clarify.
5. The rules require a 50' vegetated filter for the overflow from all infiltration systems. Please
show and detail the required filter on the plans. Include slopes, inverts, flow spreader, distances,
grass, etc.
6. According to the detail, the total infiltration trench width is 30', not 27, and the height appears
to be more than 18", as reported on the supplement. The dark line surrounding the trench in the
detail indicates that the stone extends an indeterminate amount above the pipe and 18" on each
side of the centerline of the pipes on the ends. Please revise the supplement to show the actual
stone trench dimensions and dimension the amount the stone extends above the pipe.
The provided trench volume is neither calculated nor shown on the supplement. Please show
this in the calculations and fill in the blank on the supplement.
S. Please initial page 4 of the application.

DATE: April 25, 1998
SUBJECT: Land & soils evaluation of the Marine Fisheries Tract SW Portion to determine
usability with infiltration stormwater treatment usage. Tract located on the south
side of Arendell Street (U.S. Hwy 70), adjacent to Bogue Sound, West Morehead
City, Carteret County, North Carolina.
TO: Mr. Ron Cullipher, PE (Project Manager)
Stroud Engineering Company, PA
151-A NC Hwy 24 W., Hestron Plaza II, Suite A
Morehead City, NC 28557 [phone]
The land & soils of the Marine Fisheries Tract SW Portion were evaluated to determine potential
suitability for on -site stormwater treatment usage. NCDEH&NR "Stormwater Runoff Disposal"
rules and regulations (NCAC 15-2H-.1000) were used as guidelines in making this evaluation.
This project involves redevelopment of an existing facility which requires stormwater treatment
for those portions. The proposed project is greater than 1 acre in size, has >25% impervious
surfaces, drains to Class S.A. or S.C. Waters, and is within 1/2 mile of class S.A. Waters. If a
project drains to Class SC or Unclassified Waters, stormwater may be treated by detention ponds
or infiltration basins. If the development project is within 112 mile of and drains directly to Class
SA Waters or their unclassified tributaries, stormwater must be treated by infiltration basins or an
equivalent alternative method. The tract has previously been determined to be geographically
located within 1/2 mile of Class S.A. Waters to the south, thus stormwater is to be treated through
infiltration basins. This tract has broad sandy ridgetops, that slope (-3-10%) to poorly drained flats
adjacent to Bogue Sound.
Principle soil and site requirements for an infiltration system are: ---the infiltration system's
bottom must be 2 ft or greater from the seasonal high water table; ---must be capable of
complete draw -down within 5 days; ---the soil's hydraulic conductivity must be >0.52 in/hr;
---recent fill material is not usable. The enclosed land & soils map shows the various land/soil
types found (see map). The following are brief descriptions of these land & soil types for
stormwater infiltration usage:
The "GREEN" Areas (see map) are well drained to somewhat excessively drained, deep sandy
soils. These soils have an estimated seasonal high water static water table +48 to 65 inches from
the surface based upon soil wetness indicators, —8-12 ft elevations abmsl. Estimated
permeability is <5-15 min/in (+4-12 in/hr) to +48" depths. These soil types should be considered

as suitable for shallow infiltration stormwater system usage with basin bottom depths —2-3 ft into
the ground surface. Upper soils have minor disturbance from historic surrounding development
activities, but act like natural soils. Soil types found are Wando and Alaga. These naturally
suitable soil areas should not be significantly excavated or altered.
The ' YELLOW" Areas (see map) are moderately well drained to well drained, deep sandy soils.
These soils have an estimated seasonal high water static water table between +36 to 48 inches
from the surface based upon soil wetness indicators, (-7-8 ft elevations abmsl). Estimated
permeability is <5-15 min/in (+4-12 in/hr). These soil types should be considered as suitable for
shallow placed (1-2 ft bottom depths) infiltration basin system due to seasonal high static water
table depths. Additional basin depth can be attained with above ground man-made sidewall
berms. Upper soils may have minor disturbance from historic surrounding development activities,
but act like natural soils. Soil types found are Wando and Alaga. These naturally suitable soil
areas should not be significantly excavated or altered.
The'BROWN"Areas (see map) are moderately well drained, deep sandy soils. These soils have
an estimated seasonal high water static water table between +24 to 36 inches from the surface
based upon soil wetness indicators, —7 ft elevations abmsl. Estimated permeability is <5-15
min/in (+4-12 in/hr). These soil types should be considered as suitable for ultra -shallow placed
(1-1.5 ft bottom depths) infiltration basin system with man-made sidewall berms, due to seasonal
high static water table depths. Soil types found are Conetoe and Pactolus. These naturally
suitable soil areas should not be significantly excavated or altered.
The 'PINK" Areas are somewhat poorly to poorly drained sandy soils, or significantly altered soils
from historic development activities. These soils have an estimated seasonal high water static
water table between <12 to <24 inches from the surface based upon soil wetness indicators,
—5-6 ft elevations abmsl. Estimated permeability is 5-60 min/in (1-12 in/hr). These soil types
should be considered as unsuitable for infiltration basin systems due to depths to seasonal water
table and/or mixed historic fill materials with slow permeability. Soil types found are Pactolus-wet
phase, Leon, Seabrook -wet phase, and historic dredge fill materials.
Enclosed is a representative cross-section of this tract which should be used to determine the
depths of infiltration basin bottoms in order to maintain the required 2 ft buffer from static
seasonal high water table levels (see cross-section). The tract is relatively uniform as to soil
textures, but varies significantly as to depth to static seasonal high water table levels. The better
sites for stormwater infiltration system usage are on the higher elevations, with marginal to
unsuitable sites being at intermediate to lower elevations. Careful planning and design should
be exercised to insure usable soil areas are reserved for stormwater infiltration treatment, and
relatively preserved in their natural state. Otherwise, the usable soil areas could be degraded to
an unsuitable status for stormwater infiltration basins. Soil logs can be provided upon request.

it. Clearing and grubbing of trees within the site. Excavation and grading for
the installation of parking and drainage improvements.
3. Drainage
The sites presently drains primarily to the south to Bogue Sound. (Class SA)
The site is designed to continue to drain to the south with the exception of the new
impervious area, which will drain to the proposed infiltration system in the
parking lot.
It Erosion and Sediment Control Measures
Various levels of erosion control are proposed on the plan. If it becomes evident
that additional erosion and sediment control measures are needed, they shall be
installed immediately. It is intended that all grading and excavation activities
within a certain area will be protected as soon as that activity is complete.

1 . Silt Pence — Sitt fence will be utilized as necessary in location shown on
the plans or as deemed necessary by the engineer to ensure that off -site
sedimentation is controlled.
2. Seeding —All disturbed areas will be seeded within 14 days fallowing
construction in accordance with the seeding schedule shown on the plans.
