ᐅ Driveway Drainage Slope

Hello,
I would like to have a parking space in front of my garage, so the driveway will be paved.
What I haven't figured out yet is the direction of the slope. Should it slope toward the garage or away from it?
Where should the drainage be placed?
Thank you,
Tom

Away from the garage. Usually, the local authority also requires a drainage channel at the property boundary to avoid having to manage your rainwater. This is mandatory for all sealed surfaces (such as paved areas).

Even if this sounds obvious: the slope runs from higher to lower, and the drainage must be placed at the lower end, within your responsibility. Which end is relatively higher, we unfortunately can’t tell due to your “economical” ;-) information policy. The street-side end of the area in question has to be accepted as the municipality defines the boundary of the public roadway; that’s not negotiable. The garage side is only as flexible as you are—in other words, it depends on whether you belong to the house-garage-side door enthusiasts. I would connect the garage’s finished floor level to the driveway with minimal thresholds, but depending on the slope or gradient, you need to consider that if the street is higher, rainwater would have to be intercepted by a channel drain (slot drain) or similar.

I probably already told you it’s smart not to approach the project from the back with piecemeal individual questions but to provide those advising you with comprehensive information so their assessments can be accurate.

Always direct away from buildings and ideally into a green area. Sometimes the plot layout complicates this, and drainage channels have to be used; then the question is where they are allowed to discharge.

I find all of that reasonable – but we have a rather damaged drainage system in front of the garage. Could it be possible to skip it entirely if there is a sufficient slope? It still needs to drain somewhere, though...
