Usually, a development would increase the impervious site area and create additional pollutants in the runoff. The effects of which need to be mitigated. The majority of the time there are three main elements to a stormwater management plan.
Every development is required to manage stormwater runoff. The level of complexity and detail can vary depending on the type and scale of development. It is important to consult with one of our engineers to discuss potential treatment options based on your site constraints.

Simply start the process by enquiring with us and we will get back to you with a fee proposal within 24-48 hours.
Consult with a hydraulic engineer about whether a Stormwater Management Plan would be required for your development, and what strategies would likely be needed.
Within 24-48 hours of contact we will get a fee proposal to you, highlighting our scope of work and pricing based on the specific needs of your property.
After engaging us to complete a Stormwater Management Plan 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.
Our engineers will then begin working on the assessment and discuss potential strategies, sizes and locations of various treatment options
Often the Council will want to see development plans that comply with the recommendations of the Stormwater Management Plan. Our report can be used to update development plans.
MOST FREQUENTLY ASKED QUESTIONS
As a general rule of thumb, a “lawful point of discharge” can often be thought of as a location controlled by the local authority (road, waterway, stormwater pipe, easement) and a location to which discharging flows would not adversely impact other properties.
If the development cannot comply with the lawful point of discharge requirements, then it is likely that on-site detention would be required. On-site detention systems can be above ground or under ground depending on the special requirements of the development.
Depending on the special needs of the development, water quality treatment options can be located above or below ground. There is a trade off, above ground systems are generally cheaper to install and maintain but require development space, whereas underground systems won’t take up development space but are generally more expensive to install and maintain.
Acceptable discharge methods can vary depending on the local council. There are three main methods to discharge flows:
1. Install a stormwater pipe through the downstream property (this would require consent from the downstream property owner)
2. Discharge flows via infiltration (rubble pit or soakage trench)
3. Discharge flows back up to the street via a charged line, filling the site or pumped solution.
It is important to understand the requirements of each strategy as there may be other factors that need to be considered. It would be best to discuss potential solutions with one of our engineers.
As a general rule of thumb, 4-8% of the development area would be needed for a detention system and 1-2% of the development area would be needed for a water quality treatment system.
HAVE WE DONE A JOB NEAR YOU?
The last thing you want to discover after buying land or a home is that your development plans or dream home, cannot proceed as intended due to flood overlays.
Before signing the contract, it’s essential to understand the flood risks that could significantly impact the development potential of your property or building constraints. This knowledge helps you avoid costly mistakes, make appropreiate offers, purchase with confidence, or make an informed decision to walk away.
Our consultations run up to 30 minutes, where you’ll speak directly with one of our most experienced Flood Engineers. They will guide you through the flood overlays affecting your site, explain their implications, and answer any questions you may have.
WHAT OUR CLIENTS HAVE TO SAY
WHAT MAKES US DIFFERENT
We are civil engineers that specialise in flooding and stormwater. This has allowed us to develop an in-depth understanding of hydrology and hydraulics compared to general civil engineers that are more broadly focused.
With more than 28 years of connections across the development community, we communicate effectively with the project team and other professionals within the development industry, to deliver outstanding results for our clients.
The Storm team are skilled in projects across all types of developments. We cater for a range of clientele, whether that be professional developers or first time builders, no job is too big or too small.
Our continued growth over the last 28 years highlights that we are constantly delivering our clients exceptional results, building recognition in the development community and increasing our ability to service all types of developments.
If you need a report, submit the form below for a fee proposal. We will get back to you within 24-48 hours.
Please remember that we only carry out work within the state of Queensland and some of Northern NSW.
