Driveways collect and concentrate more water than any other surface on most properties, and they deliver it somewhere — usually the garage, the lawn edge or the road.
The sloped-toward-the-garage problem
Many Lake Norman homes sit above or below the road, and a driveway falling toward the house sends every storm at the garage door.
A trench or channel drain across the driveway just in front of the garage is the standard solution, connected to a piped outlet with real capacity.
Grate strength matters — a drain in a driveway needs a load-rated grate, not a garden channel.
The outlet has to be sized for the whole driveway's runoff, which is a large volume, and kept clear of leaves.
Edges, erosion and gravel washout
Water running along a driveway edge cuts a channel in the lawn and undermines the paving edge over time.
A defined shoulder, a strip drain, or a planted swale alongside carries that flow deliberately instead of letting it find its own path.
Gravel driveways on a slope wash out repeatedly. Water bars, a proper crown, and periodic regrading manage it; steeper sections often need paving.
Silt washing onto the road or a neighbour's property is both a nuisance and a maintenance liability.
Base failure and settlement
Water travelling under a driveway washes fines out of the base, and the surface settles, cracks or ruts above it.
Recurring cracks in the same place usually mean water beneath rather than a surface problem.
Repairs that address only the surface fail again, which is why the drainage has to be found first.
Piping downspouts and roof water away from the driveway edge removes a large part of the input.
At the road and at the property line
Culverts under a driveway entrance must be sized and kept clear; a blocked culvert floods the road frontage.
Work in the public right of way generally requires approval from the relevant road authority — check before altering anything at the entrance.
Never redirect concentrated driveway runoff onto a neighbouring property.

Frequently asked questions
How do I stop water running into my garage?
A load-rated trench drain across the driveway ahead of the door, piped to an outlet with capacity for the whole driveway's runoff.
Why does my gravel driveway keep washing out?
Concentrated flow down the slope. A crown, water bars and edge drainage manage it; the steepest sections often need a hard surface.
Who is responsible for the culvert at my driveway?
That depends on the road authority and your jurisdiction. Contact them before altering anything in the right of way.
