Coastal Sea Level Rise Risk Assessor
For any coastal council or government, anywhere
Count what sits in the path of rising seas, put a defensible first number on the damage, and see who carries it. Four planning horizons, five scenarios, and a readiness rating, from figures your GIS team already holds.
Coastal Sea Level Rise Risk Assessor
A defensible first number on coastal exposure and damage, ready for disclosure and council papers.
What is inside
- Permanent inundation and 1% AEP storm tide exposure across four planning horizons
- Average annual damage, present value to 2100, and the uninsured share
- Shows how often today's 1-in-100-year event returns as seas rise
- Eight-point adaptation readiness rating with prioritised next steps and CSV export
- Printed or PDF report and data exports, as often as you like

How the assessment works
Count by elevation
Enter properties, roads and critical facilities in five elevation bands above your high tide reference. An overlay of your elevation model on the cadastre gives you the counts.
Pick a scenario
Choose an IPCC AR6 pathway, the high-end case, or the benchmark your jurisdiction has adopted. Add your 1-in-100-year storm tide level.
Read the risk profile
See exposure at 2030, 2050, 2070 and 2100, average annual damage, how often today's extreme event returns, the uninsured share, and where to start.
The bill is landing on local government
Coastal damage estimates now run to hundreds of billions this century in a single country, and many standard insurance policies exclude actions of the sea. That leaves the cost with owners and with the councils that serve them.
Climate-related financial disclosure now asks for physical risk in numbers. A screening estimate is where that starts: enough to size the problem, rank localities and make the case for detailed modelling where it matters.
Need it at property level, on your own data?
The same model can run on your elevation, cadastre and asset data as a shared platform, so neighbouring councils do not each pay for their own build.
