Stormwater Narrative
Fort Bragg Range 37 Training Annex (Modification)
This project is located on Longstreet, near the Longstreet Access Control Point, in Fort Bragg, North
Carolina. The project consists of constructing a 2480 sf addition to the existing 6200 sf building with an
existing 46 space parking lot and supporting sidewalks. The area was wooded, but some of the timber
has recently been cut. All disturbed areas will be seeded to establish a permanent vegetative grass
cover. The construction of the addition has been completed. Additional Construction of a 36 space
parking lot addition is included. The calculations and design drawings for each project are included, but
separate, within this permit modification. The parking lot addition has not been completed, while the
building addition has been completed.
This project falls in the category of a high -density project, as the impervious surface constitutes 29.7% of
the overall project site. The drainage from the high -density area is routed to an underground infiltration
basin using roof drain collection, catch basins, curb and gutter, curb inlets, and storm drainage piping.
The design of the infiltration basin is to capture the 1" storm and fully infiltrate it into the ground;
therefore, 100% treatment of the TSS load will be accomplished, as well as reducing the post -developed
discharge of this volume to 0 cfs. The infiltration basin has a drawdown time of 37.7 hours.
The off -site stormwater draining onto the site has been rerouted around the site by vegetative swales.
The remainder of the site either was routed to the new swales, to existing swales, or returned to pre -
developed sheet flow patterns.
The application form for this project contains some areas that are not applicable to this project site.

SEASONAL HIGH WATER TABLE DETERMINATION
AND
INFILTRATION TESTING REPORT
Range 37 Training Annex
FY 10. Ll 74837
Fort Bragg, North Carolina
1. PURPOSE. This report has been prepared to provide inforniation for the design of proposed
stormwater detention structures at the Range 37 Training Annex project at Fort Bragg, North
Carolina. The purpose of this report is to provide soil borings within the footprint of the stormwater
structures to determine the seasonal high water table elevations and infiltration rates for the design
of the structures. The proposed locations for the borings were provided by the AE finn, Cromwell
Architects Engineers in Little Rock, Arkansas.
2. EXPLORATION PROCEDURES.
a. Soil Survey Research. Prior to the field investigation, the U.S. Department of
Agriculture (USDA) Web Soil Survey was used to access the Cumberland County Soil Survey to
obtain an overview of possible soil series located in the project area. The project site is
surrounded by the three mapped soil series listed below.
Map Unit Symbol
Soil Series
CaB
Candor sand
I to 8 percent slopes
VaB
VauCluse loamy sand
2 to 8 percent slopes
VaD
Vaucluse loamy sand
8 to 15 percent slopes
b. Field Exploration.
(1) Subsurface conditions at the locations of the stormwater structures were explored by
two soil test borings drilled to depths of 20 and 25 feet. The borings were performed within the
footprint of the proposed stormwater detention structures at the locations shown on the attached
plan.
(2) The boring locations were established in the field by an engineer using a hand held
Global Positioning System (GPS) device having an accuracy of±10 feet. The ground surface
elevations at the boring locations were determined by interpolation from the site topography survey.
Since the measurements were not precise, the locations shown on the boring layout plan and the
elevations on the drilling logs should be considered approximate.

October 2010
(3) The borings were drilled by Froehling & Robertson, Inc. of Raleigh, North
Carolina under contract to the Savannah District. The borings were drilled with an ATV CMG
550 drill rig; a 2 1/4-inch I.D. hollow stem auger was used to advance the boreholes. Split -barrel
sampling with Standard Penetration Testing (SPT) was performed at intervals shown on the
boring logs. All soil sampling and Standard Penetration Testing were in substantial accordance
with ASTM D 1586.
(4) Representative portions of the soil samples obtained from the borings were sealed
in airtight containers and transported to the Savannah District office where they were examined
by a geotechnical engineer. Classification of the soil samples was performed in general
accordance with ASTM D 2488 (Visual -Manual Procedure for Description of Soils. Since the
soil descriptions and classifications are based on visual examination, they should be considered
approximate.
(5) Logs of the soil borings graphically depicting soil descriptions, standard
penetration resistances, and groundwater levels are attached to this report.
3. SUBSURFACE CONDITIONS.
a. Site Description. The proposed sites for the stormwater structures at the Range 37
Training Annex are in the northwest portion of the site. This portion of the site is sparsely
wooded having been timbered recently and slopes to the northwest and Longstreet Road.
b. Subsurface Soil Conditions. The USDA lists the typical soil profile for the Vaucluse
loamy sand group as loamy sand from the surface to a depth of 1.25 feet bgs. Below this a zone
of sandy clay loam extends to a depth of 4.8 feet bgs. A sandy loam layer extends to a depth of
6.7 feet bgs. The soil boring logs for the stormwater structure borings correlate fairly well with
the typical soil profile for the Vaucluse loamy sand group in Cumberland County, North
Carolina. The two borings drilled at the site contain more sandy materials especially from 3.5
to 6.5 feet bgs in boring P13-1. This subsurface description is of a generalized nature to
highlight the major subsurface stratification features and material characteristics. The boring
log should be reviewed for specific information at the boring location. The stratifications shown
on the boring log represent the conditions only at the actual boring location. The stratification
lines shown on the boring log represent approximate boundaries between the subsurface
materials; the actual transitions are typically more gradual.
c. Groundwater Conditions. Groundwater was not encountered in either boring during
or after drilling. Many of the borings previously drilled on the site have been dry. However,
groundwater was detected in three previous borings on the site; the depth to groundwater was
measured as 17 feet, 19 feet, and 20 feet bgs. It should be noted that groundwater conditions,
including perched water, vary during periods of prolonged drought and excessive rainfall as well as
seasonally. Therefore, fluctuations in the elevation of the groundwater and the occurrence of
perched water conditions should be anticipated with changing climatic and rainfall conditions.
There were no indications of a seasonal high water table within the depths of these borings. It is
recommended that the infiltration structures planned for this site be located in the sand layer at a

October 2010
depth of 3.5 to 6.5 feet has in boring PB-I and below the clay layer extending from 13.5 to 18.5
feet bgs in boring P13-2.
4. IN -SITU INFILTRATION TESTING.
Two in -situ infiltration tests were completed adjacent to boring locations PB-I and 1113-2. These
tests were conducted to determine the infiltration rate of the in -situ soils at the locations and
depths proposed for the storm water infiltration structures. The following test procedure was
used.
• Boreholes were advanced to the selected depths below ground surface (bgs), 8.3 feet for
Pl3-1 and 18.3 ft for 1113-2, using a 6.25 inch inside diameter hollow stem auger.
• Four inches of general purpose gravel were placed in the bottom of the hole.
• A 4 foot length of 4 inch PVC slotted screen with 4 inch PVC casing was installed in the
hole and the hole was backfilled with gravel to an elevation above the screen.
• The temporary wells were filled with water to the ground surface. After waiting 10
minutes the wells were refilled with water.
• The next day, infiltration tests were conducted by filling the temporary well with water to
an elevation at least 2 feet above the elevation of the screen and recording the decline in
water level over time.
• Changes in water level and elapsed time were recorded until a stabilized rate of decline
was obtained.
The results of the infiltration tests are shown in the table below.

Note: The infiltration rate of 21.6 in/hr for 1113-1 is thought to be more representative of the
sands in the 3.5 to 6.5 foot range. It is anticipated that the sandy clay loam would have an
infiltration rate similar to the rate from P13-2.
