Surface water flood mapping

[PaulaSmith1]

We are selling our house where we have been for 24 years.

The buyers search came back and we are apparently a "highly significant surface water flood risk".

In 24 years here we have had our garden flooded once and it is about 750mm below the level of the house. Our garden drains into next doors and theirs into their neighbours down the hill.

We have never had flood water in our house, neither have next doors or next to them - further than that I don't know but as they are at the bottom of the hill they might have had a problem.

Anyway - we have never been flooded but the map says we are at risk.

Have any of you had a similar problem and how did you counter it?

When we bought our house we had a similar issue come up. We paid about £100 for a more detailed report to be drawn up which reduced our risk of surface water flooding from 'med-high' to low. Maybe look into that?
To be fair though, your garden has flooded historically, it will flood again.

I am not doubting that the garden will flood again, but I doubt that the house will ever flood.

Who did the more detailed report for you and was it based on measurements of levels in your garden or just a desktop computer study?

It was one of these reports:
www.landmark.co.uk/products/flood-solutions-consult/

It is desk top based but manually assessed rather than a computer generated assessment.

I think the issue was also not the risk of surface water standing on our land, but passing through. We are effectively at the bottom of a big hill and the risk is water running down the hill and passing through. But similarly to you, our survey found the risk of water in the garden (I think that ended up at medium risk) and a low risk of it entering the house.

Thanks Sunnyday that looks helpful.
