ALTERNATIVES

The Urban Drainage and Flood Control District is engaged in a program of master
planning and construction of major drainage ways within the District Boundaries. The
expenditure of public funds by the UD&FCD and cooperating entities requires that the
most feasible potential flood control plans are identified for implementation.
Traditionally, flood control projects have been undertaken with the basic objective of
reducing or preventing damage to property. In the screening of alternatives for Direct
Flow Area 0054, twelve additional objectives have been considered, (Reference G).

the historic stream channel, using local right-of-way whenever possible.

D. The use of lined flood channels to reduce right-of-way requirements.

irrigation crossings, etc.) and channel improvements (re-alignment, erosion
