frequency of these processes are subject
to natural and artificially induced change.
–Key to the past.

–Hazards must be recognized.
–Property must be minimized.

6. Concept FiveConcept Five
• Land and water–use planning must strive
to obtain a balance between economic
considerations and the less tangible
variables such as aesthetics.
–Land, water and air are less tangible
variables.
–Less tangible variables can’t be

cumulative, and therefore, we have
obligation to those who follow.
–Population increases, Resource
decreases.

8. Concept SevenConcept Seven
• The fundamental component of every
person’s environment is the geologic
factor, and under standing of this
environment requires a broad-based
comprehension and appreciation of
the sciences and other related
disciplines.
–Limitation of existence.
–Limitation of processes.
