RE: Detailed Soil/Site Evaluation on Property Located off Highway 218., Cabarrus
County, NC — PIN: 55442997800000 (Approx. 10 acres)
Mr. Price,
This report details the findings of a detailed site and soil evaluation performed on the
tract referenced above. The evaluation was conducted at the clients written request to
determine the site's suitability for the installation of sub -surface wastewater disposal
systems to serve domestic strength wastewater. This evaluation was for commercial
wastewater applications. Any other type of use may require additional testing and/or
stricter setbacks. This report does not address systems receiving more than 3,000 gallons
per day of flow. Commercial facilities are assigned a daily design flow in accordance
with rule .1949 Table I.
The evaluation was conducted by Ryan P. Smith, North Carolina Licensed Soil Scientist
on Friday, July 23, 2021. The evaluation was conducted during dry soil conditions with
the use of a hand -auger to determine soil suitability for on -site sewage disposal systems
in accordance with 15A NCAC 18A .1900 "Laws and Rules for Sewage Treatment and
Disposal Systems". 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 this tract.
Findings are conveyed by showing areas on the enclosed map that are usable for different
system types. Areas that are suitable for conventional, modified conventional, or
approved accepted depth wastewater systems are hatched in red. These areas have usable
topography and a minimum slope -corrected soil depth of 24 inches. All hatched areas are
generated using gps technology in the field and are not survey located. The areas are
labeled with approximate square footages. Areas labeled "UNS" were unsuitable due to
depths to unsuitable parent material/saprolite, rock, soil wetness conditions (redox),
expansive clay minerology, or unsuitable landscape position.

Once the soils map is complete the size of area required for a septic system can be
estimated. Commercial systems are sized according to the number of employees in the
proposed facility or based on table I in rule .1949. A facility with 20 employees for
instance would have a daily design flow of 500 gallons. This is based on the flow of 25
gallons per employee per day. The daily flow is divided by the loading rate based on the
soil texture. This site has a clay texture so would have an estimated long-term acceptance
rate (LTAR) of 0.25 gallons per square foot of trench bottom per day. The minimum
required area or square footage on the ground for the primary septic system and the repair
area with this LTAR for the conventional hatched areas would be approximately 18,000
square feet. This area may be reduced by utilizing trench products that are granted a
reduction in linear footage compared to conventional trenches. These areas must meet all
setbacks from property lines, wells, water lines and structures as well as any other
easement imposed by other entity. Unless you pursue a private option permit, all
proposed lots/facilities will require an application and evaluation by the county health
department on an individual basis. We are 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.
We are pleased to be of service in this matter. If you have any further questions, please
feel free to call [phone] .
Sincerely,
Ryan Smith
Piedmont Environmental Associates, PA

(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

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.
