Welcome

Hello everyone and welcome to the April edition of “Keep Things Flowing”, the monthly newsletter presented by Storm Water Consulting.

Let’s begin this month’s newsletter with some handy tips and “did you know” facts about stormwater.

1.     Did you know there are four main sources of flood water that affect properties in South East Queensland? These include River flooding, Creek/Waterway flooding, Overland flow flooding and Storm-tide flooding.

2.     Not all water quality treatment and detention systems are visible when looking at a development. Systems may be located underground in an effort to maximise development yield or adhere to site constraints.

3.     Did you know a Q100 storm event is a term used to describe a storm event that has a 1% chance of occurring in any single year?

4.     Just because a neighbouring property has been developed doesn’t necessarily mean your property can be as well. Depending on the source and characteristics of the inundation the development constraints can vastly differ.

5.     Did you know that even if there is a priority infrastructure plan (PIP), you may still be required to provide detention for your development?

For more information on any of the facts or tips presented above please contact our office or reply to this email.

 

BCC Storm-tide Flooding

Brisbane City Council defines storm-tide flooding as flooding that occurs when a storm surge creates higher than normal sea levels. Areas located in Brisbane City Council that are particularly susceptible to storm-tide flooding are located within the medium or high storm-tide flood planning area overlay (as shown on BCC’s interactive mapping). Properties with either of these overlays are required to meet the requirements of the Coastal Hazard Overlay Code if development is to occur. A link to BCC’s interactive mapping is presented below.

A significant design requirement that applies to properties within the medium or high storm-tide flood planning areas is that minimum finished floor levels are to be set with an allowance for sea level rises due to climate change. The Coastal Hazard Overlay Code has been written with an allowance for up to 800mm increase in sea levels by the year 2100 and 300mm sea level increase by the year 2050. In certain cases, minimum finished floor levels may still be governed by other sources of inundation, i.e. overland flow, creek/waterway flooding or Brisbane River flooding.

If you would like help with identifying the governing source of inundation on a property and the consequent minimum finished floor level requirements please contact our office.

 

Services

Civil engineering is comprised of a number of different strands. Whilst the team here at STORM are civil engineers, we specialise specifically in the hydraulics sector. We are often asked if we provide certain aspects of analysis or design work. Presented below is a summary list of the different services we provide:

·         River, Creek and Overland Flow Analysis

·         Detention Basin Design

·         Water Quality Treatment Design

·         Pipe and Culvert Design

·         Rainfall Analysis

·         Channel Design

·         Stormwater Drainage Design

·         Expert Witness and Litigation Work

·         Design Consultation

·         Lawful Point of Discharge Identification

If your development requires any of the services listed above we would be pleased to provide you with assistance. For a detailed summary of each of the services we provide please visit the services section of our website via the link below.
