Flood Management and Risk Assessment Services

Professional Stormwater and Flood Risk Solutions

Our flooding and stormwater engineering services can be broken down into three categories. If you are unsure whether we can help you, please feel free to call or email us.

Properties flagged as containing overland flow, creek, river or coastal flooding require assessment against Council regulations. We are able to provide the following to help get you your builds through the Development Approval process:

  • Flood impact assessment

  • Minimum design levels

  • Flood levels, depths, velocities and hazards

  • Compensatory earthworks

  • Flood storage volumes

New developments can increase the amount and alter the characteristics of runoff generated from a property. We are able to provide the following to help get you your builds through the Development Approval process:

  • Lawful point(s) of discharge

  • Water quantity measures eg. On-site detention

  • Water quality measures eg. Proprietary devices

  • Stormwater collection, treatment and release strategy

Private Works Investigations

If you have experienced flooding on your property and are looking for measures to prevent such occurrences in the future, we are able to provide the following for temporary or permanent fixes:

  • Site-specific flood assessment and/or modelling

  • Analysis of probable flood levels, depths, velocities and hazards

  • Recommendation of stormwater devices

  • Recommendation of property alterations

Hydraulic flood modelling services are used for the following purposes:

  • Planning for emergencies, such as periods of intense rainfall, and designing systems that can cope with high volumes of sudden, unexpected water incursions.

  • Developing approvals to meet council requirements, including instituting evidence-based flood mitigation strategies.

  • Flood risk assessments determine the potential impacts of flooding on buildings, people, and surrounding structures.

  • Designing infrastructure to manage stormwater flows, including swales, detention basins, and additional flow-mediating systems.

Our services also include:

  • Local and regional catchment delineation

  • Hydrologic analysis utilising catchment slopes, routes, impervious values, rainfall intensity data, ground infiltration and more

  • Hydraulic flood modelling simulating design events and project scenarios utilising ground surface elevations, stormwater infrastructure, surface roughness values, general infrastructure, hydrograph data and more

  • Concept digital elevation models

  • Flood risk assessments

  • Flood sensitivity analysis

  • Development layout strategies (flood mitigation)

  • Model results calibration analysis

  • Stormwater infrastructure capacity calculations

  • Flood timestep analysis

  • Form 12 and Form 15 certification

  • Private flood assessment documentation

  • DA flood assessment documentation for local authorities

  • Council application and data assessments

  • Council flood study analysis and modification

  • Client, consultant, stakeholder and council meetings

  • Site inspections and investigations
