Flood Impact Assessment

1% AEP · Development

Overview

A flood impact assessment only earns its purpose if it survives the regulator reading it line by line — the standard here is written for that reader, not for a quick sign-off.

Capabilities

1% AEP and development-standard flood assessments built to Australian Rainfall & Runoff methodology, with assumptions documented well enough to be interrogated
Rapid, repeatable assessment across large property or site portfolios when an event has already happened and impacts need to be established at pace
Findings that separate what actually changes flood behaviour from what doesn’t — the distinction most reviewer pushback comes down to
Assessment scoped from the outset to feed straight into design once approval lands, not re-run as a separate exercise

The projects that move fastest through review aren't the ones with the least detail — they're the ones where every number can be traced back to how it was derived. That's the bar the assessment is written to.
