"Any further discussion?"

"I'd like to make inquiry as a matter of
information. We have authorized some of these
resolutions in the past, for instance I think
down in the Littleton area, have the munici-
palities followed up on this and actually
put in zoning regulations?"

"Some communities, Boulder, the metro-
politan area, and Pueblo, have been quite
aggressive in this field and are adopting
or have adopted zoning ordinances."

"What do the zoning ordinances do? Pro-
hibit the building in the flood plain area?"

"Yes. The zoning ordinances prohibit the
erection of structures in the flood plain
area, anything that would endanger human lives
or cause additional flooding. One of the
major causes of floods is the debris which is
swept into the channel. For instance, in '65
there would have been a minimum of damage to
structures on the South Platte had it not
been for the thousands of tons of debris that
lodged against these structures. The debris
created dams which then raised the water level
and caused it to overflow over greater areas
than it would have had there been no obstruc-
tions in the river. The bridges would have
withstood the impact of the water but they
could not withstand the trucks and trailers
and trees that lodged against the structures
and created dams. The water pressure was in-
creased perhaps fifty times greater than what
the river would have produced in the way of
pressure without the debris. It is the debris
that creates the major problem. If the chan-
nels can be kept clear then the river can
take care of itself without excessive damage."

"Larry, let me ask you this question. I
take it then that these zoning ordinances
are not only going to be aimed at the building
