<p>I don't have my own definition, and I don't want to make
up a new one. A quick search revealed these:</p>

<div style="direction: inherit;"> </div>
<div style="direction: inherit;"> </div>
<div style="direction: inherit;">the definitions you found are
all reasonable for natural=floodplain and are all describing
the same situation, although with different focus on which
aspect is named.</div>
<div style="direction: inherit;"> </div>
<div style="direction: inherit;">The definition given above in
this thread describing government dedication of land is not
suitable for the natural tag and should go into the boundary
tag (and subkeys), if entered into osm at all.</div>
<div style="direction: inherit;"> </div>

<div style="direction: inherit;">Exactly, problem solved. Despite
the title, this thread is not about flood plains, but designated
flood risk zones. Conflating them with floodplains is wrong.</div>

<br>
NO!<br>
<br>
I gave a link to a document with a map of a sample area... it
contained that statement.. at NO time was I proposing using that
definition (which I had not read .. I was simply looking for an
example of the area).<br>
<br>
But by all mean misconstrue it whatever way you want ... <br>
<br>
The problem is how to tag floodplains.. so far this is diverted
into;<br>
<br>
how to define it ... <br>
how to determine it ... with some accuracy (why? Where is the
accuracy in determining a woodland? Where is the accuracy in
determining an area of sand? They are all 'fuzzy' ... they are all
indications .. not absolutes. <br>
I sure there will be other topics of equal value to someone ... with
some link to tagging a floodplain. <br>
<br>
So ... thanks ... I'll just go do mapping it the way I think would
be best. Bye. <br>
