STORMWATER MANAGEMEN PLAN:
SPRING LAKE KINGDOM HALL
SPRING LAKE, HARNETT COUNTY, NORTH CAROLINA
JAN, 2013
LOCATION
This site is located on a secondary state road (Raynor Road - SR 2052) approximately 600 feet
east of the intersection of NC 210 and SR 2052 on the north side of SR 20525 in an
unincorporated area of southern Harnett County, North Carolina.
SITE DESCRIPTION:
The site is a gently sloping (2%+-), cleared site previously possibly used for agricultural
purposes in the past. No improvements are present on the site. Soil types on this site consist of
predominantly Norfolk loamy sand (No). The Seasonal High Water Table was estimated at
36" below the ground surface in the area to be utilized for treatment. A soil report with Ksat
infiltration results is attached.
There are no wetlands or streams located on the property
PROPOSED PROJECT
The proposed project consists of the construction of a 5,000 SF single story building and
associated paved parking. The total disturbed area is approximately 1.6 acres. The project
includes site building sewer to on -site septic disposal and water tap for water.
The front half (south and bulk of development area) of the site drains into the existing state
road ditch and the property to the south east where it eventually discharges into the Upper
Little River in the Cape Fear basin. The back half of the site (north and predominantly the
septic disposal area) of the site drains overland across adjacent property (same ownership) to a
natural swale and eventually to the Upper Little River.
An offsite area drains to the site from the west (approximately 1.2 ac.) and is currently or
intermittently cultivated farm land. Runoff from this area will be collected, treated, and
discharged from the site.
Stormwater Management - In accordance with NCDNR's interactive map, this site is subject
to state Phase II water quality treatment regulations.
E
STORMWATER MANAGEMENT MEASURES:
The soil analysis of the site in the area to be utilized for treatment indicated low Ksat
infiltration rates (0.29 in/hr). This infiltration rate is below the threshold for an infiltration
BMP. The SHWT was estimated at 36" below the ground surface. This depth combine with
the relative low elevation differential across the site rendered a Bioretention BMP to be
impractical. A stormwater wetland is proposed which will meet the Phase II treatment and
discharge control requirements.
The proposed wetland has been sized to accommodate the on and off site drainage areas and
routing is attached showing no increase in the discharge for the 1 year - 24 hour storm in
accordance with the Phase II requirements. The basins are capable of containing the expected
runoff volume from the 1, 2, 10, 25-yr storms without increased discharge to surface waters.
An analysis point was chosen at the south west corner of the site where discharge occurs from
a combination of the existing DOT roadway ditch and the proposed wetland outlet. Results are
tabulated below:

Re: Hydraulic conductivity (permeability) analysis & seasonal water table determination
(SI-I WT) for stormwater retention area, Kingdom Hall (Spring Lake) site, PID 010524
0018 18, Raynor Road, Harnett County, North Carolina
Dear Mr. Smith,
An evaluation of soil properties and hydraulic conductivity (Ksat) has been conducted at
your request on the aforementioned property. The purpose of the investigation was to
determine soil water table depths (SI-1 WT) based on soil profiles. In addition, Ksat was to
be provided at a depth 2.0 feet above the SH WT elevation for use with stormwater
retention basin design.
Saturated hydraulic conductivity of the unsaturated zone was measured in a similar
method as described in the Soil Science Society of America Journal, Vol. 53, no 5, Sept. -
Oct. 1989, "A Constant Permeameter for Measuring Saturated Hydraulic Conductivity of
the Vadose Zone" and Comparison of the Glover Solution with the Simultaneous
Equations Approach for Measuring Hydraulic Conductivity." This consists of advancing
a small diameter bore hole to a predetermined depth (typically 2 feet above SHWT). At
this depth, a constant head (pressure) was established and maintained. Flow
measurements were made at timed intervals after flow stabilized.
Soils at the proposed basin site are most similar to the Norfolk soil series (see attached
boring log). Two borings were advanced to 8.0 feet. Seasonal High Water Table
(SI-I WT) as determined by evidence of colors ol'chroma 2 or less (and/or concentrations
of high redox mottles) was encountered at a depth of 36 inches below the ground surface.

GROUNDWATER DRAINAGE/MOUNDING • SURFACE/SUBSURFACE WASTE TREATMENT SYSTEMS, EVALUATION 8 DESIGN
Two compact constant head permeameter (CCHP) tests were Conducted at it depth of 1.00
feet below the ground sttrfitce. The measured Ksat rate in boring I was 8.05 em/hr
(equivalent to 3.17 inches/hour). The measured Ksat rate in boring 2 was 0.73 cm/hr
(equivalent to 0.29 inches/hour).
fhe attached map shows locations of the sample points as well as Ksat location.
It should be noted that the reported SH W"f does not necessarily reflect the elevation of
static groundwater (due to variations in groundwater recharge rates. annual rainfall_
drought conditions, etc.).
The data presented in this report are limited by a number of considerations. The primary
consideration is that soil formations can be highly variable. The sails found on this site
can be subject to inclusions of other soil types; perched water. artesian conditions and/or
layers of undulating low permeability clay seams. These and other soil conditions can
have an affect on the steady state of groundwater flow. To the extent possible, we have
identified the soil types that will impact the flow of groundwater, and have provided a
professional opinion as to the depth of SII WT.
I trust this is the information you require at this time.
Sincerely,
�Zz�y

Re: Preliminary soil evaluation for subsurface waste disposal, +/- 2 acre combined tract
(PID 010524 0018 & 010524 0018 19, Raynor Road, Harnett County, North Carolina
Dear Mr. Smith,
A preliminary soils investigation has been completed for the above referenced tract at
your request. The property is located on Raynor Road as illustrated on the accompanying
map. The purpose of the investigation was to determine the extent of soil areas that may
have the ability to support a subsurface waste disposal system for a proposed church
facility [total facility flow of 720 gallons per day; up to 240 sanctuary seats u 3 gallons
per seat per day; no fellowship hall]. All ratings and determinations were made in
accordance with "Laws and Rules for Sanitary Sewage Collection, Treatment, and
Disposal, 15A NCAC 18A .1900".
Southeastern Soil and Environmental Associates, Inc. (SSEA) performed these soil
evaluations in February, 2012. SSEA traversed the property and observed landforms
(slope, drainage patterns, etc.) as well as soil conditions through the use of hand auger
borings and/or soil probes.
Soils on this site are dominantly suitable or provisionally suitable for a subsurface waste
disposal system to serve the proposed facility. Typically, these soils exhibited 10 or more
inches of fine loamy sand underlain by sandy clay loams to depths of 48 or more inches.
Soil wetness, depth, and mineralogy were typically provisionally suitable to depths of at
least 36 inches. A 720 gpd church facility would require approximately 12,000 sq.11. of
this soil area for drainfields and repair areas (exclusive of setbacks from lot lines,
facilities. etc.). (Note: These square footage recommendations assume appropriate
SOIL/SITE EVALUATION • SOIL PHYSICAL ANALYSIS • LAND USE/SUBDIVISION PLANNING
GROUNDWATER DRAINAGE/MOUNDING • SURFACE/SUBSURFACE WASTE TREATMENT SYSTEMS, EVALUATION & DESIGN
topography for a practical septic system layout on topographical contour. Space
requirements could increase with difficult topography, irregular lot lines, etc.) The initial
septic system in these soil types would require a 1,500 gallon septic tank with a
conventional drainlield (GOO linear leet of conventional drainline based on an [A -Alt of
0.4 gpd/sq. ft. installed on contour).
Note: Any site grading or soil removal in these suitable or provisionally suitable
areas may alter the findings of this report and render sites unusable. Areas for
septic disposal must remain undisturbed (no mechanical clearing, stripping,
excavation or heavy traffic).
Southeastern Soil and Environmental Associates, Inc. is pleased to be ofservice in this
matter. We look forward to assisting in additional site analysis or septic design needs you
may have in the future. Please feel free to call with any questions.
Sincerely,
Mike Eaker

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 90 % confidence interval. The probability that precipitation frequency estimates (fare
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 (Pi estimates and may be higher than currently valid PMP values.
Please refer to NOAA Atlas 14 document for more information.
