❑ Coastal SW -1995 ❑ Ph II - Post Construction
3 Stormwater runoff from this project drains to the White Oak River basin
4 Total Property Area 3 02 acres
5 Total Coastal Wetlands Area 0 acres
6 Total Surface Water Area 0 acres
7 Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project
Area' 3 02 acres
Total project area shall be calculated to exclude the followui the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the ormal High Water (NHW) line or Mean High Water
(MHVV9 line, and coastal wetlands landward from the NHW (or MHW) line The resultant project area is used to
calculate overall percent built upon area (BUA) Non coastal wetlands landward of the NHW (or MHM line may
be included in the total project area
8 Project percent of impervious area (Total Impervious Area / Total Project Area) X 100 = 40% (Includes BUA
prior to 1988 %
9 How many drainage areas does the project have? 1 (For high density, count 1 for each proposed engineered
stormwater BMP For low density and other projects use 1 for the whole property area)

Before you issue this permit, please consider the following
J 1 David Huss is the architect not the POC for the inspections department
/ 2 Use the 10 yr/24 hr design information in the permit, i e 6 85" design storm and it s volume and the
,/volume infiltrated in 24 hours Keep the 7401 cf volume provided
3 Include the River Basin information for Broad Creek, i e , WOK03 in the permit This is part of the index
number
�y Don't refer to page numbers in the permit only refer to Section and Condition numbers
. Don't use red ink in the headers Edit the head and change the ink color to black
6 The depth of the basin is not 2 5 feet — it s 2 0 The bottom is at 24 and the emergency overflow is at
260
Even though the permittee signed an O&M for the original permit back in June this is a modification, so
a new O&M for that basin is required You cannot use the old one in this case, because the basin it is
associated with has been changed
8 Don t forget to include a list of the modifications It appears that one of the two permitted basins is being
eliminated?

Patty,
Can you get another signed / notarized O&M Agreement for the revised infiltration basin? This is a legal requirement
since the design of the basin has changed slightly with this modification

DESIGN NARRATIVE
1 GENERAL
The project site is located along NC Highway 24 and is approximately 0 9 miles east of the
intersection of NC Highway 24 and Broad Creek Loop Road in Newport, N C The intent of
this project is to construct a new building with associated parking, storm drainage and storm
water management device
2 EXISTING SITE
The existing site is located in the coastal area and is not within % miles of SA waters The site
is currently developed that includes fire station and EMT facility Topographically the site is
mostly flat (approximately 0 50%) with runoff from this site being collected into road side
ditches The runoff from the site eventually enters into the Broad & Gales Creek (Stream
Class SA, HQW)
Based on Carteret County Soil Survey, the existing sods are WuB (Wando), Se (Seabrook)
and KuB (Kureb) The hydraulic sod group used was "A " The FEMA Flood Insurance Rate
Map (Panel 6306) shows the project site to not located within a flood hazard area The USGS
map, the Carteret County sod survey map, and the FEMA map are included in this report
3 PROPOSED IMPROVEMENTS
This project will have a disturbed area of 153 acres, in which the majority of the disturbed area
will be utilized for the construction of the building, parking areas, stone drainage, and
infiltration basins
The site will be graded such that the majority of stormwater runoff from the proposed
improvements will be directed by sheet flow to the infiltration basin shown on plan sheet C-4 0
Runoff from the impervious areas built after 1988 will be collected in storm pipes/french dram
system and directed to the infiltration basin A complete set of calculations, including hydraulic
grade line calculations, for the stormwater drainage are attached
Stormwater Control and Treatment
The current NCDENR Coastal Stonmwater Rules require the control and treatment of runoff
generated by the first 1 5' of rainfall, or the difference in the stormwater runoff of pre -
development and post -development conditions for the 1-year, 24-hour storm, whichever is
greater The Simple Method was used to determine which runoff volume was greater
The Infiltration Basin was designed to handle runoff generated from a 1 56 acre drainage area
as shown on enclosed Map 2 Calculations resulted in the volume generated by the 1-year,
24-hour, storm (3 65") being greater than the volume generated by the first 1 5" of rainfall
therefore, the basin was designed for the volume generated by the 3 65" rainfall event

Water Quantity
Routing results prove that both infiltration basins meet pre -post development conditions for the
1-year, 24 hour stone Furthermore, both basins contain the 10-year storm and therefore,
vegetated filters are not required See table below for results of pre -post development
calculations

See the Hydraulic Summary's for 10-year storm routing and maximum elevation results
A soil evaluation prepared by Fred D Smith Sod Consulting, Inc dated October 141", 2011,
states that the infiltration rate of the existing sods range above 0 52 inches/hour, which would
be favorable for the design of an infiltration device Infiltration rates ranged from 35 9 in/hr to
71 6 in/hr The infiltration rate of 17 95 in/hr (50% of 35 9) was used in design of the infiltration
basins Furthermore the seasonable high water table was observed to be approximately 78
inches below the surface
4 EROSION CONTROL AND MAINTENANCE CONSIDERATIONS
Temporary silt fence will be placed along the lowest sides of the limits of disturbance to
cleanse stormwater runoff before leaving the site Temporary diversion ditches will be installed
to direct stormwater runoff from the site to sediment basin Inlet protection will be placed
around all new drainage structures that may be affected by the proposed construction
Calculations for the design of the sediment basins are attached All erosion control measures
are documented on the enclosed erosion control plan
Contractors shall be responsible for periodic inspection and maintenance of all indicated
erosion control devices In addition, inspection and any necessary maintenance will be
required immediately following any significant storm event Any measure that fads to function
as intended shall be repaired immediately Upon completion of construction, the property
owner shall be responsible for site maintenance

Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS)
Numbers in parenthesis are PF estimates at lower and upper bounds of the 9D% confidence interval The probability that precipitation frequency estimates (for a
given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5% Estimates at upper bounds are not
checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values
Please refer to NOAA Atlas 14 document for more information

Preclpnetion frequency (PF) estimates In this table are based on frequency analysis of partial duration Genes (PDS)
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence Interval The probability that precipitation frequency estimates (for a given
duration and average recurrence Interval) will be greater than the upper bound (or less than the lower bound) is 5% EadmBtea at upper bounds are not checked against
probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values

Subject. Report of a Sod Evaluation for Stormwater Treatment
Gales and Broad Creek Fine Station
Hwy 24
Dear Ms Hilburn,
This letter concerns the soil evaluation I performed at the above mentioned site You authorized
me to perform a sod evaluation of the surface soils on the site to determine the depth to the
`seasonal high water table', and to perform in -situ sod permeability testing at the site
You provided me with site drawings that show the existing and planned buildings The site
currently is occupied by a parking lot for the fire station I understand that the fire station will
have an addition buck.
My work consisted of hand auger borings to observe and describe physical properties such as
texture, color, structure, consistency, depth to seasonal or perched groundwater, parent
material, and restrictive horizons The soils are described into the USDA sod classification
system
The sod is formed from wind blown and marine deposits of sediments

The soils are deep sands that do not exhibit any cemented layers or cementation of sand grams
(or shallow seasonal water tables) which are typical in the area
Groundwater was encountered below about 92 inches beneath the surface The seasonal high
water table at this site is about 78 inches beneath the surface where sod moisture significantly
increased Gray colors that are indicative of seasonal water tables were present at this depth
The soil permeability of the soil layers at the site was measured using an Aardvark Soil
Permeability The Aardvark Permeameter maintains a constant head of water in a bore hole
The rate of water movement is measured over tune_ The results are entered into an Excel
spreadsheet program that computes the permeability value in inches per hour
The Aardvark field forms are attached The test results are presented below The approximate
locations of all bongs and tests are shown on the accompanying drawing.
Prior to beginning the tests, the bore hole was allowed to soak for about 15 minutes Tins is to
fill the sod pore spaces around the boring so that saturated hydraulic conductivities are
measured

The above saturated hydraulic conductivity rates are average rates I suggest that a
safety factor be used for design purposes Generally, the academic and regulatory
community agrees with using 10% of average conductivity for a safety factor In
addition, the column on the attached permeability field report forms shows a `Design
Loading Rate in gallons per square foot per day' that has a 10% safety factor
Thank you for selecting me to assist you with this project Please contact me if you have
questions or need additional information
