What slope is still comfortable?

Hello guys,

I am planning to have a descent built from the driveway, which is 2.5m above garden level, so that I can also get into the garden with a wheelbarrow.
To calculate the angle stones, I need to consider the slope.

What slope do you still find acceptable so as not to pick up too much speed?
Is 15° (26.79%) too much?

What are your experiences?

Regards
Tito

Hello everyone,

I am planning to have a descent built from the driveway, which is 2.5m above garden level, so that I can also get into the garden with a wheelbarrow. To calculate the retaining stones, I need to consider the slope.

What slope do you still find acceptable to avoid gaining too much speed? Is 15° (26.79%) too much?

No idea if there are regulations on this. But with that slope, you’d have to close off the descent at the latest when it rains, because you’d break your neck. And at the given slope, you’re already looking at almost 10m length of the descent… maybe someone with experience will chime in, but I’d rather consider steps.

Just for comparison: For a barrier-free ramp for wheelchairs, max 6% is allowed. At 10%, cyclists start to get off slowly. Your 26% might work with a wheelbarrow, but it definitely won’t be fun. And on top of that, there’s a slipping hazard, especially if you’re carrying a load from above. I’d skip it.

That's too much. If you also have children or access from the neighborhood, you won't be happy with it anymore.

So I do have children, small children... What do you mean by "access from the neighborhood"? I have to say that the exit is really only supposed to serve as a "driveway" for the 500 m² garden to move materials. We have access via stairs on the other side of the house from the terrace.

At some point, I'll be annoyed that I can only go down steps when I have to transport things for the garden design, the garden shed, etc. Or when I store the bicycles underneath... or put the trash cans down there so they don't look ugly in front of the house...

Well, if you have children, they will surely get visitors to play with. Let something happen on the ramp, especially since children don’t hold onto stairs anyway and slopes are magically attractive.

How did you imagine getting up?

My father once had a similar access to the cellar, a slope for carts. He then screwed U-profiles across the ramp; otherwise, you can’t get back up the ramp.

You should think everything through carefully. Maybe a small spiral path would also be an option, that is, to stretch the route and reduce the slope.

Maybe I just lack the feeling for the slope at first. I need to see how and where I can test that best. I would have thought roughly 25% is not much. A height difference of 1m over a distance of 4m.
