Most of the buildable land left around McCall sits on a slope. The flat, forgiving lakeside parcels are long gone. What's left (ridge lots, lake-view benches, timbered hillsides) is where the good views are, and where the real site work lives. A steep lot doesn't mean a hard build. It means the decisions you make before framing matter more than the ones you make during it.
Read the lot before you draw the house
We walk a steep lot in all four seasons when we can, or at minimum in the shoulder seasons. You learn where the snow piles, where runoff cuts a channel, and where the shade lingers into June. A soils report tells you what's under the duff: decomposed granite, glacial till, or clay that turns to soup every spring. The geotech drives footing depth, retaining strategy, and whether a daylight basement is a basement or a structural experiment.
- Slope percentage across the footprint, not just the average
- Frost depth and soil-bearing values from a licensed geotech
- Surface drainage paths during snowmelt
- Sun angles in December (the views are only half the story)
Site the house to the grade, not the grade to the house
Cutting and filling a hillside into a flat pad is the old way. It costs more, it looks forced, and it creates drainage problems that follow you for thirty years. A home designed to step with the grade (walk-out lower level, split foyer, cascading decks) usually moves less dirt, needs less retaining, and sits on the land like it belongs. That's the starting premise of our process: the house comes out of the lot, not the other way around.
Access is a year-round problem
A driveway that works in August can be impassable in February. Grade, turning radius, and snow-storage area all matter. The county caps driveway slope at 12 percent in most cases, and you want well below that if you're not planning on heated driveways. Fire code also requires a turnaround and adequate width for apparatus on longer drives. We design for that upfront so the approval comes clean.
Retaining walls: earlier is cheaper
If the site needs retaining, we'd rather engineer it into the foundation than bolt it on afterward. Segmental block walls over four feet need engineering anyway, and a properly designed ICF or reinforced concrete wall integrated with the foundation almost always outlasts a stand-alone retaining structure. Drainage behind the wall matters more than the wall itself. Weep systems and proper backfill are what keep it standing.
Erosion and sediment control during construction
Valley County requires an erosion-control plan for steep-slope permits, and the county inspectors take it seriously. Silt fence, stabilized construction entrances, and staged clearing aren't paperwork items. They're how you keep topsoil out of the creek and the project out of trouble. We stage the work so the ground is never bare longer than necessary, and we reseed cut slopes the same season they're cut.
Utilities follow the easy path
Bringing power, water, and septic up a steep lot is its own small project. We map the trenching corridor before we finalize the footprint so lines don't cross under driveways or decks, and so rock outcrops get avoided rather than blasted. On lots with well and septic instead of city services, the drainfield location often drives the house location more than the view does.
Every steep lot tells you what it wants to be if you read it carefully. If you're weighing a hillside parcel and want a second opinion on what it'll take to build on, reach out.
