OVERLAND FLOW & FLOOD ASSESSMENTS

WHAT IS A FLOOD ASSESSMENT?

It is essential to get a Flood Report by a Registered Professional Engineer of Queensland (RPEQ) Flood Engineer to support your development application if your property is located within a flood affected area.

Flood water can originate from several different sources, these include overland flow, creek flooding, river flooding, coastal and storm-tide flooding. A Flood Report is an assessment that identifies the extent and nature of flood water. The assessment also aims to demonstrate that the proposed building works or development would comply with Council’s Flood Overlay Code and Flood Planning Scheme Policy.

Some of the items that would normally be completed involve setting floor levels to meet flood immunity requirements, assessing the hydraulic impacts of the building works or development, and assessing the potential for isolation and evacuation from the site.

The Process

Simply start the process by enquiring with us and we will get back to you with a fee proposal within 24-48 hours.

Enquire with Us

Consult with a hydraulic engineer about your property’s flooding potential and how this may affect your development application or building application to the council. We can talk through the potential issues and solutions available for your development.

Fee Proposal

Within 24-48 hours of contact we will get a fee proposal to you, highlighting our scope of work, timing and pricing based on the specific needs of your property.

Site Inspection

After engaging us to complete a flood report for your property or development, one of our engineers will contact you to set up a time to conduct a site inspection. Often it is beneficial to meet on site so that we can explain solutions and strategies for your development.

Flood Assessment

Our engineers will then begin working on the flood modeling specific to your property and work with you to deliver the best flood-related solutions for your build that satisfy the requirements of the council’s flood policies.

Lodge
Application to Council

Once our report is complete and has met the requirements set by the council, you are ready to lodge your building or development application.

FAQ

MOST FREQUENTLY ASKED QUESTIONS

When Do I Need A Flood Report?

A flood report is generally required when your property is located within one of Council’s Cityplan Overlays. The Cityplan Overlays can be viewed on Council’s interactive mapping website.

The cost of a flood report can vary depending on the complexity of the flood modelling required. It would be best to contact us so we can talk through the flooding requirements. We can often give you an initial indication of a price over the phone or via an email before validating the estimate with a formal fee proposal.

Our average turn around time on a project is about two weeks. This accounts for projects already in our pipeline as well as the time it takes to undertake your assessment. We will give a more accurate estimation of timing on our formal fee proposal.

A flood report would provide you with an assessment of the different sources of flooding and design criteria to comply with the local Council’s flood code. Our report can generally be used to complete design plans and lodge an application with Council.

If your property is located within one of the Council’s flood overlays, it is likely that you will need a flood report. Both a private certifier and the Council’s development assessment team will require this report to ensure that the flooding requirements of the planning scheme policy are met.

I engaged Gurinder Babra of Storm Water Consulting to undertake a Flood Study Report for a residential property I was raising and developing. This property was in an overland flow path which created challenges with building under the property, and issues relating to not adversely affecting any neighbouring properties. Gurinder and his team were efficient, and completely across all the compliance issues I had to meet in order to satisfy my development application with my local Council. Thanks to Gurinder we came up with a solution that enabled a great design outcome that satisfied the DA conditions attached to our application. Thanks again Gurinder and Storm Water Consulting. Regards Andrew
