Welcome

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.

 

Subdivisions

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.

Other stormwater issues that would also need to be investigated include:

·         Flood free trafficable access;

·         Lawful point of discharge;

·         Flood hazard assessment.

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.

 

QUDM Training Course Update

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

 

Christmas Break

Storm Water Consulting will be closing over the Christmas – New Year period. The office will be closed from Thursday 21st December 2017 – 5th January 2018, with the office reopening on Monday 8th January 2018.
