Dear Mr. Smith:
ECS Carolinas, LLP (ECS) recently conducted a determination of Class IV soils for the 19.4
acre site located at 7170 Carolina Beach Road in Wilmington, New Hanover County, North
Carolina. This letter, with attachments, is the report of our determination.
According to the Soil Survey of New Hanover County, North Carolina, Cass IV soils are a
capability class of soils that indicate limitations for practical use. Class IV is described as soils
that have severe limitations that make them unsuitable for cultivations. Class IV soils are
defined by the Technical Report No.9, Wilmington – New Hanover County Comprehensive
Planning Program as soil series Dorovan (DO), Johnston (JO), Pamlico Muck (Pm), and Tidal
Marsh (TM). The Technical Report No.9 also specifies that the groundwater elevation should
be encountered at six inches below the existing grade elevation or has standing water. The
county soils map illustrates that soil series Pm covers approximately 1/3 of the site, as is
concentrated in the center portion of the site (Figure 1).
Field Observations
On June 7, 2016, ECS conducted an exploration of the subsurface soil conditions at the site to
determine the presence or absence of Class IV soils (Figure 1). ECS explored the subsurface
soil and groundwater conditions by advancing a hand auger boring into the existing ground
surface at multiple random locations across the site. ECS concentrated the borings within the
mapped area of the Pm.
The soils within the Pm area were observed to be a black to gray fine sand from 0 to 24 inches
without encountering the groundwater table. These soils appeared most similar to series Lynn
Haven fine sand (LY) which is mapped on the southeast corner of the property. LY is described
by the soil survey as black fine sand 18 inches thick with a gray fine sand subsurface layer that
is 6 inches thick.
There is a Pocosin mapped in the northwest corner of the site and there is a jurisdictional
wetland located within that area. The rest of the site is mapped as a soil series Kureb sand 1 to
8 percent slopes (Kr) and soil series LY. The soils observed appeared to closely represent the
soils series indicated on the map.
