Dear Mr. Manning,
This report details the findings of a detailed site soil evaluation performed on a portion of
approximately 65 acres located off Stockard Road,future phase 8 of Cane Creek subdivision,tax
map number 8-14-1 in Alamance County,NC. The evaluation was conducted at the client's
request to determine the site's suitability for the installation of sub-surface wastewater disposal
systems to serve domestic strength wastewater. This report does not address systems receiving
more than 3,000 gallons per day of flow. A preliminary site plan was provided by the client's
engineer.
The evaluation was conducted by Ryan Smith,North Carolina Licensed Soil Scientist. The
evaluation was conducted during moist soil conditions during July 7-9,2020 with the use of a
hand-auger. Characteristics that affect the suitability of sub-surface systems include soil depth to
expansive clay, seasonal high water table,rock, and unusable saprolite. Topography and slope
also affect the suitability of an area for septic systems. The evaluation of these components was
conducted on the site. The level of the evaluation was detailed for the subject area.
Findings are conveyed by showing areas on the enclosed map that are usable for different system
types. Conventional areas are hatched in red and have usable topography and a minimum soil
depth of 24 inches. Areas that are not hatched are generally unsuitable due to topography and
depths to seasonal high water table and rock. Some areas that were not hatched may be useable
after an investigation utilizing backhoe pits to evaluate the soil. The hatched areas are generated
by using a global position system in the field. These areas are not surveyed and therefore may be
lacking in accuracy.
Once the soils map is complete the size of area required for a septic system can be estimated.
Systems are sized according to the number of bedrooms in the proposed dwelling. Each bedroom
in the proposed dwelling is calculated to generate a daily flow of 120 gallons. A four-bedroom
dwelling would have a daily calculated flow of 480 gallons. The daily flow is divided by the
loading rate based on the soil texture. This usable soil on this site has a clay texture so would
have an estimated loading rate of.25 gallons per square foot of trench bottom per day. Unless
you decide to pursue a private option permit,this loading rate will eventually be determined by
the local health department. This division would result in the required trench bottom area of 1920
square feet. The trenches are three feet wide which means the total trench length for a gravel
conventional system would be 640 linear feet. The common approved accepted chamber type
systems would require 25%less trench length or 480 linear feet of trench. These trenches are
spaced on nine-foot minimums widths and must converge and diverge with contour. The
conservative estimate of the area required for the initial and repair for a four-bedroom home with
a conventional type system on this tract is approximately 16,000 square feet. The approximate
216 S Swing Rd Suite 1 . Greensboro, NC 27409 . 336-260-3564

area required for a chamber type system is 12,000 square feet. The area required for a three-
bedroom home on this tract is approximately 12,000 square feet for a conventional initial and
repair and 8,000 square feet for an accepted 25%reduction system initial and repair.
A CAD file will be sent to your engineer to assist with planning the lot configuration.Prior to
final recordation of the plat an application must be made to the Environmental Health section for
an Improvements Permit for each lot,unless you decide to pursue a private option permit. System
layouts may be required as part of the permitting process. We recommend having a backhoe
provided during the evaluation of each lot due to the varying depths to usable saprolite across the
site. We will be glad to assist with the permitting process.
This report discusses the general location of potentially usable soils for on-site wastewater
disposal and the soil and site limitations on the property that exists at the time of the evaluation.
Piedmont Environmental Associates,PA("Piedmont")provides professional consulting
specializing in the practice of soil science and wastewater management. Piedmont is therefore
hired for its professional opinion regarding these matters. Laws and rules governing wastewater
treatment and disposal are forever evolving and subject to the interpretation and opinion of
individuals which are employed by local and state agencies that govern these laws and rules. Due
to this fact,Piedmont cannot guarantee in any way that any area located in the field, shown on a
sketch,or discussed with the client will be permitted by any of these agencies. It is for this
reason that Piedmont strongly recommends to anyone considering a financial commitment
on any piece of property be completely aware of any and all permit requirements on that
property before purchase and obtain those permits prior to a final financial commitment.
If you have any further questions please feel free to call me at(336)260-3564.
Sincerely,
Ryan P. Smith

.1950 Location of Sanitary Sewage Systems
(c) Every sanitary sewage treatment and disposal system shall be located at least the minimum
horizontal distance from the following:
(1) Any private water supply source including a well or spring 100 feet
(2) Any public water supply source 100 feet
(3) Streams classified as WS-I 100 feet
(4) Water classified as S.A. 100 feet
from mean high water mark
(5) Other coastal waters 50 feet
from mean high water mark
(6) Any other stream,canal,marsh,or other surface waters 50 feet
(7) Any Class I or Class II reservoir 100 feet
from normal pool elevation
(8) Any permanent storm water retention pond 50 feet
from flood pool elevation
(9) Any other lake or pond 50 feet
from normal pool elevation
(10) Any building foundation 5 feet
(11) Any basement 15 feet
(12) Any property line 10 feet
(13) Top of slope of embankments or cuts of 2 feet or more
vertical height 15 feet
(14) Any water line 10 feet
(15) Drainage systems:
(A)Interceptor drains,foundation drains and storm water diversions

(ii) sideslope 15 feet
(iii) downslope 25 feet
(B)Groundwater lowering ditched and devices 25 feet
(16) any swimming pool 15 feet
(17) any other nitrification field(except repair area) 20 feet
(b) Ground absorption,sewage treatment and disposal systems may be located closer than
100 feet from a private well supply,except springs and uncased wells located
downslope and used as a source of drinking water,repairs,space limitations and other
site-planning considerations but shall be located the maximum feasible distance and,
in no case,less than 50 feet.
(c) Nitrification fields and repair areas shall not be located under paved areas or areas
subject to vehicular traffic. If effluent is to be conveyed under areas subject to
vehicular traffic,ductile iron or its equivalent pipe shall be used. However,pipe
specified in Rule.1955 (e)may be used if a minimum of 30 inches of compacted cover
is provided over the pipe.
Note:Systems over 3000 GPD or an individual nitrification fields with a capacity of 1500 GPD or more have
more restrictive setback requirements,see.1950(a)(17)(d)for specifics.
