Writing a flood risk assessment if carefully done is a largely scientific process. By “scientific” we are alluding to the fact that the content is grounded in fact, or at least as far as the available data is accurate.
If a flood of a certain depth is “forecasted” when viewing available flood data for the site then we can raise the building up. Facts and reactions to those facts. This is what we like.
One part of the Flood Risk Assessment is the Sequential Test. This “non-scientific” part of the Flood Risk Assessment we could do without. It is a policy based, almost artistic endeavor that relies on the matching of unqualified of opinions, sometimes resulting in mismatches.

The sequential test relies on the following ingredients in order to work:
- search area
- search criteria
Both of these ingredients are open to debate in terms of their size and type respectively, and as such we have to be careful to follow established guides that have been issued by some of the more proactive administrative authorities’ so that we can demonstrate plausibility.
