Techno babblers - get real
Richard, Stuart - get real.
I was realy impressed by the content of the web site. Ten years ago no-one would expect the level of detail contained in the property by property advice telling you how much flood water to expect. Now you are complaining about not being able to see it when riding your pushbike.
What the hell are you doing riding around the streets anyway? Get home or get to a safe place.
A lot of the information on the Brisbane Council web site is in PDF. You may find it difficult, but I have no problem enlarging and scrolling about a PDF on my mobile.
You can search - the old fashioned way. Look for your suburb on http://www.brisbane.qld.gov.au/community/community-safety/disasters-and-emergencies/BRFFS/index.htm (this was noted in your update). In each PDF look up your street - and then check your street number. Is that too difficult for you?
This level of detailed advice is amazing. I am really impressed.
