Drainage That Works With the SlopeFoothill lots shed water downhill whether you plan for it or not. We design grading, French drains, and catch basins that move water off your yard and away from your foundation.
Our Orangevale shop is a short drive away. Same crew, every project.
Where Granite Bay Water Goes Wrong
Water on a foothill lot has two jobs. It has to get off your property, and it has to stay away from your house. Where your lot sits on the slope decides which job is failing.
| Your lot | What the water does | Where we start |
|---|---|---|
| A slope rises above your house | Storm runoff arrives from uphill and heads for the foundation | Catch the water above the house and steer it around |
| Your yard sits at the bottom of a slope | Everything from above collects at the low spot | A catch basin at the low point, tied to a safe outlet |
| Thin soil sits over a harder layer | Water soaks in, hits the hard layer, and sits like a bowl | Regrade the surface and add a French drain to carry water out |
| A big roof with few downspouts | A lot of water lands in one small spot beside the house | Pipe the downspouts away from the walls |
Many lots near Folsom Lake have more than one of these problems at once, which is why we walk the whole lot before we draw a plan.
How We Fix a Granite Bay Drainage Problem
Every fix follows the same order, no matter how big the lot is:
- Trace the water from where it starts to where it stops.
- Regrade the yard so water has a clear path off the property.
- Add French drains to collect water moving through the soil, and catch basins to grab surface water at low points.
- Tie the system to a safe outlet, so water ends at the street or another proper exit and not against a wall, a foundation, or a neighbor's fence.
On larger sloped lots we often use French drains and catch basins together, so the drain catches water along the slope and the basin picks up what is left at the bottom.
Placer County Rules for Granite Bay Drainage Work
Granite Bay is unincorporated, so Placer County sets the grading and drainage rules here instead of a city hall. The county requires a grading permit for fill or excavation over 250 cubic yards, for grading in a floodplain, and for grading within or next to a drainage course or wetland. Its code also says grading cannot block or interfere with a drainage channel, ditch, or pipe.
Many yard drainage fixes are smaller than the permit limit. A lot beside a creek or a drainage course is a different story, and so is any plan that sends water toward a shared path or a neighbor's line. We check your lot before we dig, so the fix does not fail an inspection or push your water problem onto someone else.
The county also follows Low Impact Development practices that keep rainwater soaking into the ground close to where it falls, and you can read about them on the Low Impact Development page. For the full range of what we handle in town, visit our page as a landscaper in Granite Bay, CA.
Signs Your Granite Bay Yard Has a Drainage Problem
Walk the lot after the first big storm of the season. These are the signs to look for:
- Water still standing at the low end of the yard a day or more after the rain stops.
- Soil or gravel washed onto the driveway or against a wall.
- Small gullies cut into a slope, or planting beds that keep washing out.
- A wet or soft strip along the foundation.
- Water crossing your property line from a neighbor's yard, or the other way around.
If you see any of these, take a few photos while the water is still there. They help us trace where it comes from.

Questions About Drainage Solutions in Granite Bay, CA
Does McGuire Earth Works fix drainage problems in Granite Bay?+
Yes. Our shop is in Orangevale, a short drive away, and we fix drainage on foothill lots in Granite Bay. Slopes, thin soil over rock, and big roofs on large homes all move a lot of water in a storm. We trace where the water comes from first, then build a system that catches it and sends it somewhere safe.
Why does water pool in my yard if the soil is rocky?+
Many Granite Bay lots have thin soil sitting on top of a harder layer. Water soaks in fast at first, then stops when it hits that layer and sits like water in a bowl. Runoff from the hillside above can also arrive on your lot during a storm. We find the spot where the water actually stops, and fix it there.
What is the difference between a French drain and a catch basin?+
A French drain is a gravel-filled trench with a perforated pipe. It collects water from soggy soil and moves it away underground. A catch basin is a box with a grate on top. It collects surface water from a low spot and sends it into a pipe. On sloped lots we often use both. The French drain catches water along the slope, and the catch basin picks it up at the low point.
Do I need a county permit for drainage work in Granite Bay?+
Sometimes. Placer County requires a grading permit for fill or excavation over 250 cubic yards, for grading in a floodplain, and for grading within or next to a drainage course or wetland. Many yard drainage fixes are smaller than that. A lot beside a creek or a drainage course is different. We check the rules for your lot before we dig.
