What We Do
Landworks has been providing flood reports for many years, with a team of stormwater and flooding experts who understand Auckland’s unique drainage challenges. We specialize in computer-generated flood modelling that accurately predicts how water behaves on your site during extreme rainfall.
From this modelling, we offer clear and practical advice, including easy to read drawings and reports that outline how flooding can be managed on your property.
We support homeowners, developers, and property professionals with:
- 2d and 3d flood modelling using Hec-Hms and Hec-Ras.
- Flood Risk Assessments to support Resource Consent applications.
- Stormwater Infrastructure and overland flow path management designs.
- Advice to homeowners with flood affected properties.
- Retrospective flooding and overland flow path designs for works already completed.
Please contact us about your stormwater requirements and let us show how we can assist.
Auckland’s Anniversary Weekend floods
Following the floods in early 2023, it’s more important than ever to ensure you’re receiving the right advice about flooding risks on your property. Flooding in Tāmaki Makaurau Auckland is becoming more frequent and severe due to intense rainfall, climate change, and increased urbanization.
Whether you’re buying, selling, building, or just want peace of mind, understanding your property’s flood risk is crucial.
At Landworks, we help homeowners, developers, and property professionals understand and manage flood hazards across Auckland.
What causes flooding?
Flooding often occurs when:
- Heavy rain overwhelms the stormwater network.
- Overland flow paths are blocked by structures or fences.
- Properties or dwellings sit lower than the surrounding land.
- Increased impervious area within the catchment increases the stormwater runoff.
Even small changes to ground levels or fencing can worsen the risk—for you and your neighbours.
Is your property at risk?
Use the Auckland Council Flood Viewer to check whether your home or site is in:
- A floodplain
- A flood-prone area
- An overland flow path
- A coastal inundation zone
