Exhibit I — Soils Information
A web soil survey was conducted with the Natural Resources Conservation Service (NRCS). The
results of which are summarized in the table below. The NRCS web soil survey provided a .zip
file containing GIs information which was used in the production of the Soils Information Map
contained in Exhibit C.
Name NRCS Abbreviation Percent of the Affected Land
Truckton Loamy Sands TtB 84.54%
Ascalon Sandy Loam,0 to 3
Ash 10.63%
Percent Slopes
Platner Loam PIB 4.12%
Ascalon Sandy Loam, 3 to 5 AsC 0.71%
Percent Slopes
A large majority of the affected lands, 98.09 of the 116.02 acres, is comprised of what the NRCS
considers Truckton Loamy Sand (TtB). Truckton series are usually found as native pastureland
but are used for dryland crops in some instances.The typical profile of this series is 60 inches
thick and consists of either loamy sand or sandy loam. The suitability of the Truckton series as
topsoil is described as poor to fair(Sampson &Thomas, 1974) and is a class 6e soil when non
irrigated (National Cooperative Soil Survey, 2020).
The next most abundant area of soils is the Ascalon Series. The Ascalon Series covers
approximately 17.11 of the 116.02 acres of the site. The typical usage of this series is for dry
and irrigated croplands or for grazing with the native vegetation would mainly be short grasses.
The typical profile of this series is 60 to 80 inches consisting of sandy loam or sandy clay loam.
The suitability of the Ascalon Series as topsoil is described to be fair to poor (Sampson &
Thomas, 1974) and is a class a 4c soil when non irrigated (National Cooperative Soil Survey,
2020).
The final soil that was shown to be present on the affected lands is the Platner Series.This
series covers approximately 4.78 acres and is located completely on the south central portion
of the affected land. The typical usage of this series is for dry and irrigated cropland or native
pastureland. A typical profile of the Platner Series is 60 to 80 inches thick and consists of layers
of loam, clay and sandy clay loam. The suitability of the material as topsoil is described as
generally fair but good in the upper eight inches (Sampson &Thomas, 1974) and is a class 4s
soil when non irrigated (National Cooperative Soil Survey, 2020).
