In my opinion, since the roadway isn't a tunnel under the waterway,
the layer tag should be the same as the waterway.
This sounds more logical to me. The waterway includes the full depth of
water down to the bed.

landuse comes to mind which isnt that far removed from a river area.
Another thought, is how will a ford be rendered

This is a permanent waterway (the Shoalhaven River), and is quite wide
at the ford to keep the water depth low.
I would drop the layer tag, they still physically intersect.
As for rendeing, I've filed a ticket:

There's a very sensible proposal for tagging fords which overcomes the

Interesting. Some fords are across permanent waterways, and there're

a design is suggested but it needs drawing out so it can progress through

anyone can make a set of icons (for different colours of roads)?
I was revisiting fords because I noticed an icon already in use

The -1 layer tag accurately describes the situation when the ford=yes

Depends which side the range you are on, east of it they are often wet.

Not to mention the difference between a ford and a floodway. Sometimes
the distinction isn't clear, and best left to the mapper.
What is the difference between a ford and a floodway/causeway? I
thought they were the same thing.

Ok, so flood plain or flood prone areas...

This is all off the top of my head, but a ford will generally have
flowing water, and a floodway not (or be more slowly flowing).
A ford generally crosses a stream

Most floodway signs don't require slowing unless it's raining.

I understood after Liz's photos, I'm used to them being referred as
flood plains.
