budgeting stage if it does not:

1. Satisfy needs of a group of citizens and

2. Accomplish this in a sufficient manner to warrent

funding from a limited financial resource base. That

is to say, the project must win the right to be funded

in a complex evaluation process.

In order to gather information needed for this complex evaluation

process three hierarchies of information are needed:

~

1. The operational goals and objectives of the UDFC system.
(To be distinguished from general, broad .urban goals).
e.g., "To provide adequate drainage for minor runoff
events (say 2-year frequency) at minimum annual cost."
Of course, the selection of such an operational goal
should qe subject to a tradeoff analysis after the cost
of achieving the goal is known.
2. The measures of effectiveness needed to determine the
extent to which ,alternative projects meet the above goals.
(Costs and Benefits).
3. The coefficients and ranking scales needed to arrange
the measures of effectiveness into a decision-making order.
In the analysis of UDFC projects, several distinct evaluation sub-
problems appear. A good systems analysis or planning process will begin
with establishment of objectives and measures of effectiveness, move
into formulation of alternative solutions, evaluation and tradeoff
analysis, and finish with a selection or decision stage. The use of
this procedure depends on the stage of planning or implementation,
