. debris basins or detention dams;

. levees and channels;

. drop structures;

. debris fences;

. local dikes:

. street orientation and design:

. elevation of structures;

. watershed manag~ment; and

. flood plain zoning.

2. The design of management tools must consider the
following criteria:

. performance requirements specifying the depth,
velocity, and discharge which must be
controlled:
. identified flood hazards and the susceptibility
of the tool to those hazards;
. physical constraints such as available land:
. public acceptance potential: and
. cost.

3. A management tool selection process which considers
these criteria is recommended, as follows:

. identify the type and location of flood
hazards:
. develop quantitati~e estimates of flood depth,
velocity, and path:
. identify existing and future development
through the creation of a master plan:
. develop alternative flood management scenarios
using different tools;
. eliminate tools that are ineffective or will be
se~erly damaged by flood hazards;
. estimate the cost of alternative scenarios; and
