Hello everyone and
welcome to the October edition of “Keep Things Flowing”, the
monthly newsletter presented by Storm Water Consulting.
This month we discuss
how to subdivide flood prone land within Brisbane, we bring you
another update for our new QUDM training course and we announce our
Christmas/new year holiday closure dates.
Over the past few
months we’ve had a number of development enquiries about
subdividing land that is subject to flood water. Subdividing flood
prone land is often difficult because Brisbane City Council do not
want to intensify land use in flood prone areas. Creating flood
prone lots increases the strain on emergency services and puts more
of the population at risk of injury or death. The Flood Overlay
Code requires all newly created lots to provide a minimum of 300m2
of flood immune land area. The purpose of this requirement is so
that a dwelling, unaffected by flood water, can be constructed on
the new lot. The number of people at risk during a flood event
would therefore not be increased (assuming trafficable access is
not an issue).
To achieve flood
immune land area, the flood water would either need to be diverted
away from the new lot, or the lot would have to be filled above the
flood level. Both of these solutions divert the flood water onto
neighbouring land, which could cause an adverse impact to the
neighbouring land. An assessment of the impacts caused by filling
the lot or diverting the flood water would need to be undertaken by
a hydraulic engineer. If it can be demonstrated that the flood
water could be diverted without adverse impact then subdividing
could potentially occur.
issues that would also need to be investigated include:
· Flood free trafficable access;
· Lawful point of discharge;
Prior to purchasing a
flood affected block for the purpose of subdividing, give our
office a call to discuss the associated risks and likelihood of a
subdivision application being approved.
Last month we announced that we
would be hosting training courses for the newly released Queensland
Urban Drainage Manual (QUDM). We have since partnered with the
Institute of Public Works Engineering Australasia (IPWEA) to
organise and present these training courses.
If you would like pricing and booking details
for the course please contact Craig Moss via email at Craig.Moss@ipweaq.com

closing over the Christmas – New Year period. The office will be
closed from Thursday 21st December 2017 – 5th January 2018, with
