House on a slope - high surface water flooding risk

Jac0915

Hi
I am a first time buyer and I am thinking to buy a house on a slope.  The house is on a cul de sac street, but at a significantly lower lever than the street as it slope downward from the street to the front door to the back garden, and continues slope down to a common green space, which I think is the lowest point.
It is marked as a high surface water flooding risk on UK government website
The houses are semi detached and so in theory (as a laymen observing the terrain) I think the water can also go down thru the driveway between the houses, then down to the garden to the common green space, avoiding flooding the house with flood barrier.

Another one I am interested is on medium surface water risk.  It is next to a very busy main road and on a level slightly lower level than the road and the garden also sloped downward more gently.

Thoughts and advice for considerations?  Other than flooding, for a house building on a slope , is it a concern for future maintenance?

Any retaining wall is a concern for future maintenance - depending on how much it's retaining, and how well it was built in the first place.

You'd like to think that ground water run-off has been considered. Given the amount of rain so far this year and early last, if there was a real issue, then you would be seeing evidence of that.

Ask the vendor if there has been any flooding before? My house is high risk surface flood and it has never flooded in 30 years.
