Coastal hazard assessments

Worried about coastal risks like erosion or flooding? We’ll help you identify the hazards before you start developing. Whether it’s rising sea levels, storm surges, or erosion, we make sure your project is safe, compliant, and future-proofed. We’ll assess all the critical factors—like historical trends, sea level rise projections, and storm surge patterns—to keep your coastal development on solid ground.

Coastal hazard mitigation

Once we’ve identified the risks, we’ll establish erosion buffers and inundation protection—minimum finished floor levels, tailored to your location. We take into account everything from wave setup to local erosion rates, so your development can weather any storm.

Consent documentation

Our minus the fuss approach

We’re by your side from initial assessment to project sign off, providing the expertise you need every step of the way.

1. Site Investigation

We conduct thorough coastal hazard assessments, evaluating key factors such as historic shoreline change, tides, storm surges, projected sea level rise, wave setup, and local erosion rates. This helps us identify potential risks to your site.

2. Evaluate

We analyse the assessment data to fully understand the coastal hazards at your site—whether it's the risk of erosion inundation from storm surges, or the impact of rising sea levels—and recommend the best course of action.

3. Design & Solutions

Based on our findings, we set minimum finished floor levels and establish erosion setbacks.

4. Reporting

Our detailed reports outline the hazard risks and risk management strategies. These reports can be included in your development plans and submitted as part of your resource consent application to local authorities.
