Scope and Requirements of the Study

The total Cottonwood Creek Drainage

Basin has been studied at two previous times, although for different

purposes. The first basin study was prepared for the City of

Colorado Springs in 1969, for use as a drainage planning guide.

The U. S, Corps of Engineers, Albuquerque office, studied the basin

in 1976 to define the then existing probable flood plain, This

use in determining areas

available for Federal Flood Insurance.

study was completed for the Pikes Peak Council of Governments, for

study was completed prior to any large scale urban development in

the basin, and under the City of Colorado Springs rainfall criteria

of that time, It is desirable to update Basin Studies to correct

for differences in actual development from those planned at one

time, and to implement newly developed criteria. The flood plain

study is precisely that; a defined area which would be flooded if

certain conditions prevail and no changes in drainage are considered,

Studies of this type also require periodic review to take into con-

The total basin has, until recently,

developed in a random man~er, The upper basin has developed slowly

south of the Black Forest line, with most existing development

being of the 1 to 5 acre site type, An area of approximately 2

square miles within the Black Forest was developed nearly 15 years

ago, but has grown slowly. The middle basin contains some
