A flood risk assessment helps you find out if water will damage your home and is often required to get building permission.
A Flood Risk Assessment (FRA) is a detailed report. It looks at a piece of land or a building. It checks if that land might flood now or in the future.
The report looks at many things. It looks at the history of the area. It looks at how high the land is compared to nearby water. It also looks at how much rain falls. Modern reports use smart maps to make these checks very accurate.
You usually need this report for two main reasons:
For simple projects, you can look at a government map yourself. But for big projects, you need an engineer. They use computers to see exactly where water will flow during a big storm.
Not all floods come from the same place. It is important to know where the water starts.
This happens when a river gets too full. The water spills over the banks and onto the land. This is the most common type of flood people think about.
This happens when it rains very hard and very fast. The ground or the drains cannot soak up the water quickly enough. The water then sits on top of the roads or flows into garages. This is a big problem in cities because there is a lot of concrete and not enough soil.
This happens near the ocean. High tides and strong winds push sea water onto the land. This can be very dangerous because of the salt and the force of the waves.
Getting an assessment is a step-by-step process. Follow these points to stay safe.
Start by looking at your local government website. They have maps that show Flood Zones.
If your land is in Zone 2 or 3, you need a special report. An expert will visit your property. They will check the height of your floors. They will also make sure your new building does not make flooding worse for your neighbors.
The rules for building are very strict. The government wants to make sure people do not build homes that will just get ruined by water.
Before you build in a flood area, you must prove there is no better spot. The “Sequential Test” asks: “Is there a drier piece of land nearby?” If the answer is yes, you might be told to build on the drier land instead.
If you must build in a flood area, you have to pass the “Exception Test.” You must show that the building provides a big benefit to the local town. You also have to show that the building will be safe and dry for a long time.
If your report says you have a risk, do not worry. You can do things to stay dry.

The price changes depending on the size of the land. A simple report for a house might cost a few hundred dollars. A big report for a new neighborhood can cost thousands.
You can check the basic maps yourself to see the risk. However, for a formal planning application, the council usually requires a report from a professional engineer.
No. Weather patterns change over time. It is best to get a new report if your old one is more than two years old to make sure the data is still correct.
Not always. Most reports suggest ways to fix the problem. You might just need to change your building design to keep the water out.
In many urban areas, surface water from heavy rain is the most common cause because the water has nowhere to go.
