RE: Revised Soil Hydrologic Groups

The Soil Conservation Service has checked our hydrologic group assignments. They
report three errata: Map unit 7B should be a "D" hydrologic group, and map units 13A
and 18Ap should both be 65%C and 35%D.
Reproductions of the SCS maps are available from Tucson Blueprint.
