This information, a{ong with the soil map and other
parts of this publication, can be used to make interpre-
tations in addition to those given in tables fi and i, and
it also can be used to make other useful maps.
This informatiml. ho+eever, does not eliminate need
for further investi~rations at sites selected Cnr engineer-
ing +corks, especially works that invnlce heavy loads
or that require excavations to depths tmeater than
those sho+vn in the tables, generally depths mm'e than
G feet. Also, inspection of sites, especialk the small
ones, is, needed because many delineated areas of a given
soil mapping writ may contain small areas of other
kinds of soil that have strongly contrasting properties
and different suitabilities m• lunitations fm• soil engi-
neering.
Some of the terms used in this soil survey have
special meaning in soil science that may not be fami-
liar to engineers. 7•he Glossary defines many terms
commonly used in soil science.
