When developing in flood-prone areas, understanding and managing flood risks is crucial for compliance, safety and project cost. Our flood study and flood related consulting services provide expert guidance at key decision points in your new land/property purchasing and existing property extension development journey.

What is a Flood Study Report?

A Flood Study Report is a detailed technical assessment that evaluates flood risks in a specific area. It examines factors such as rainfall patterns, catchment characteristics, topography, and drainage systems to model flood behaviour—including flood extents, depths, velocities against different frequencies (e.g., 1-in-100-year flood events). The report helps identify vulnerable areas and provides essential data for flood mitigation and property development planning like building finish floor levels.

Why Do You Need a Flood Study Report?

When a proposed development is located within a flood-prone zone, local councils often require a flood study to assess potential impacts on the existing floodplain and neighboring properties. This process ensures that the development does not worsen flooding risks and complies with floodplain management regulations.

A well-prepared Flood Study Report is crucial for safety, legal compliance, and cost-effective development in flood-prone zone.

When to Engage Our Flood Study Services for Property Development

To ensure your property development is flood-resilient and council-compliant, our flood risk consultancy services can assist at key stages of your project:

1. Initial Flood Consultation (Early-Stage Advice)

✅ Best Time to Engage:

• Before purchasing land (to assess flood risks and avoid costly surprises).
• Before planning an extension or development (to understand constraints).

🛠 How We Help:

• Desktop Flood Risk Review – Check council flood maps, historical data, and planning controls.
• Preliminary Hazard Assessment – Identify if the site is in a high-risk flood zone (e.g., overland flow path, riverine flooding).
• Feasibility Advice – Recommend whether to proceed, modify plans, or avoid the site.

💡 Why It’s Important:

• Avoid buying uninsurable or flood-prone land.
• Save time & money by addressing flood risks early.

2. Detailed Flood Assessment (For DA/CDC Approval)

✅ When You Need This:

• When submitting a Development Application (DA) or Complying Development Certificate (CDC).
• For new builds, subdivisions, or extensions in flood-prone areas.

🛠 Our Services Include:

• Hydraulic & Hydrological Modelling – Assess flood behaviour (TUFLOW, HEC-RAS, etc.).
• Impact Assessment – Prove your project won’t worsen flooding for neighbours.
• Flord Certificates & Justification Reports – Meet council /CDC requirements.
• Mitigation Design Recommendations – E.g., raised floor levels, detention basins.

📋 Council Submission Support:

• Ensure your application complies with local floodplain management policies.
• Help respond to council requests (e.g., RFIs, additional studies).

Key Benefits of Engaging Us Early

✔ Avoid Rejected DAs – Flood issues are a common reason for council refusal.
✔ Reduce Construction Risks – Prevent future flooding damage to your property.
✔ Faster Approvals – Our reports meet council standards, speeding up the process.

Next Steps for Your Project

• Buying Land? → Get our Initial Flood Consultation to assess risks before purchase.
• Submitting a DA/CDC? → We’ll conduct a Detailed Flood Assessment for council DA/private CDC approval.
