Drainage / Problems / Bluff and waterfront

Bluff and waterfront property

On a bluff, the question isn't just where the water collects. It's where it ends up, and the bank is the worst place for it.

What's actually happening

Much of our shoreline sits on layered glacial deposits: sand over silt, with till in between. Water soaks in, meets a layer it can't pass through, and comes out on the bluff face as seepage. Roof water and driveway runoff pointed toward the bank make it worse, and a pipe that spills over the edge can cut a gully in a single winter.

On a bluff, the aim is to move water away from the bank, not soak it into the ground near it.

Rain gardens and dry wells that suit an inland lot can be the wrong answer on a bluff.

What we'd look at

Where roof and drive water goes

Every downspout and hard surface, and whether any of it runs toward the bank.

Seeps on the face

Where water is coming out of the bluff, and what layer it's riding on.

A safe outlet

A tightline carried down to the beach in a controlled way, or water sent away from the slope entirely.

Permits and setbacks

Bluffs and shorelines are regulated areas. Some work needs county review or a geotechnical report first.

When the slope itself is the problem

If the bank is cracking, slumping or already moving, we don't just pipe the water over the edge. We bring in a licensed geotechnical engineer to look at the slope, and we build the drainage to their design. We drill for engineering firms every week, so we know who to call and how to work alongside them. You get one point of contact and a fix that's been checked.
