Drainage ability under Burnby Street Hemmant
This is an exposure of the lack of maintenance to the local drainage system.
(No document on this web site supports the following statement at this time.)
I have read within the Brisbane City Council's Bulimba Creek Flood Study that when Bulimba Creek is in flood and the flood waters are restricted at the Rail Bridge at Hemmant the flood waters can flow east to Main Drain and Lindum Creek on their way to the Brisbane River.
Just what obstacles are there in flood waters path.

After correspondence with Inghams Head Office Queensland I was told that the drains were working properly and did not need to be upgraded.
In the Bulimba Creek Flood Study I read several years ago it said that when Bulimba Creek was in flood and the flood waters were restricted by the rail bridge at Hemmant the flood waters could flow east to Lindum Creek and flow under the rail line there.
That means that to flow to Lindum Creek the flood waters must first pass under or over this private road owned by Inghams.

The text from the flood study will appear when I have the time to scan a copy for the web site.
Then let us not forget how the water flowing east enters Lindum Creek.

And these culverts are on Brisbane City Council Land west of and to adjacent to Kianawah Road.
