To whom it may concern:
I have used the soil survey maps of the NRCS and the location provided by Donna Reed to
determine the soil on the site in question. The predominant soil on this site is Ascalon loam. A
description of the soil and a map from the NRCS manual is included with this letter. The soil
survey is not site specific and other soil types may be present in small amounts in isolated areas.
