I disagree that it is a very bad idea. The primary database isn't the right place for it though. 

The appropriate place would be in the historical (OHM) database.

In the long term mapping of flooding, bush fires, droughts, etc will become a useful resource for the increasing numbers of ordinary people studying these types of events, especially with climate change becoming more obvious.

I have been in a position where this a more micro mapping of flood data would have saved me both time and money. This time last year I was planning to move from Brisbane, Queensland to Northern New South Wales. At that time there had been some major flooding. If I had reasonable micro mapping of those flood areas I could have saved my self an 800km trip to the areas I was focusing on because I would have been able to compare the flood mapping with locations I was considering and seen that all the properties within my budget were within the flooded but not included in the official, historical flood risk areas.

To sum up, fine grade mapping of transient climatic data can be very useful to more than just professional but it isn't relevant on a street map.
