What is a Coastal Hazard Vulnerability Assessment (CHVA)?

A CHVA is a specialized report and analysis required by local councils in coastal regions—such as across Victoria, Australia—as part of the **planning permit process** for new developments. It assesses and maps the site's vulnerability to coastal hazards.

What key risks are addressed in a CHVA report?

The assessment focuses on hazards that will increase due to climate change and **sea level rise**, primarily: **coastal erosion**, **coastal flooding** (including storm surge and storm tide inundation), and long-term shoreline recession.

What information is included in the final CHVA report?

The report provides an expert analysis of the site’s risk profile, detailed coastal erosion and coastal flood mapping (showing risks over time), and an initial assessment of risk **mitigation options** for the property.

COASTAL RISK MANAGEMENT REPORTS (CRMR ) in NSW

What is a Coastal Risk Management Report?

When is a CRMR Required?

A Coastal Risk Management Report (CRMR) is a specialised assessment required to demonstrate that a proposed development is safe, resilient, and compliant with NSW coastal planning requirements. It thoroughly investigates a property's vulnerability to existing coastal hazards as well as potential future risks arising from climate change and sea-level rise.

If you are planning to build or redevelop on land located within a mapped coastal hazard zone in New South Wales, your local council will typically require a CRMR. This ensures your project complies with specific regional planning schemes, such as the Eurobodalla Coastal Hazard Code, and is designed to withstand coastal impacts over its entire design life.

What Our CRMR Service Includes:

**1. Coastal Hazard Assessment Scope:**
We evaluate coastal inundation risks, mapping the impacts of extreme storm tides and wave runup.
We analyse coastal erosion hazards, factoring in long-term shoreline recession and potential slope instability.
**2. Tailored Management Strategies:**
**Nominated Flood Protection Levels (NFPL):** We calculate the required NFPL to establish safe and appropriate habitable and non-habitable floor levels for your development.
**Structural Design Recommendations:** We provide expert specifications for flood-compatible materials—such as reinforced concrete, waterproof masonry, and hot-dip galvanised steel—to ensure the building can withstand hydrostatic pressure and saltwater exposure.
**Service Design Requirements:** We outline strict flood-resilient utility designs, which include elevating electrical switchboards above the NFPL, using sealed conduits, and implementing sewer backflow prevention devices.
**Evacuation Strategies:** We develop comprehensive emergency response procedures, warning systems, and safe evacuation routes to protect occupants during severe weather events.
Don't let complex coastal planning controls stall your NSW development. Contact OMCN today for a site-specific Coastal Risk Management Report.
