"I've identified where
and when floods have
occurred, and who they
affect. Now what?"

You've made the initial identification, now it's
time to gather more thorough data to ad-
equately assess flood risk in your community.
If the affected area is small-one or two
houses-the amount of detail needed will be
minimal; it really depends on your community.

Your planner and DNR noodplain specialist
(see Appendix A) can help you decide how
much infonnation you need to measure flood
risk by property and community-wide. Here are
some general categories to use. You may not
need all of them; these are only examples:

1 Age and condition of affected
structures

Categorize structures by damages suffered,
flood depths, nooding frequency, types of
damage (overland, groundwater, back-up);
amount of damage (per building, event, year);
who paid for repairs; age; condition; construc-
tion (brick, frame, iron, etc.); and suitability for
current and intended use.

2 Age and condition of
infrastructure

Assess condition and utility of roads, bridges,
dams. sewage treatment plants, wells,
stormwuter systems, mass transit systems and
other affected infrastructure. Even though
buildings in the area may be viable and worth
saving. the support systems may be too expen-
sive or physically difficult to repair.

Often a community can't afford the time or
staff to do a complete inventory from scratch.
