<br />The report co~tai~s maps, profiles, and cross o~ctions
<br />which indicate the extent of flooding th~t may occur in the future
<br />in the stream reach studied. This should prove helpful in plan.
<br />ning wise use of the flOod plains. From th~ ~eps and profiles, the
<br />depth of probable flooding by the Intermediate Regional or Standerd
<br />Projeot flood at any location m~y be e~timated. With this inforna_
<br />tion, floor levele for buIldings mey be planned high enough to avoid
<br />flood damage or, If et lower elevations, with recognition of the
<br />chances and halerds of flooding that or" i'wolved.
<br />The report does not include plane for the sol"tion of
<br />flood problems. Rather, it is intended to provide the basis for
<br />further study and planning on the pert of the city of Monte Vieta
<br />end Rio Grande County. In developing local planning progr~ms, con_
<br />sideration should be given to providing instructions for disaster
<br />opBr~tions, controlling d~velopments in the flood plain through
<br />zoning ~nd subdivision regulations, and including ~ppropr1ate struc.
