Retaining walls in Post Falls, ID
From new subdivisions on the prairie to homes along the Spokane River, get connected with a builder who works Post Falls.
Post Falls mixes flat, fast-growing neighborhoods on the Rathdrum Prairie with steeper ground along the Spokane River. Wall projects here often look different from Coeur d'Alene's hillsides: grade changes between new lots, walls along driveways and patios, and landscaping walls on flatter ground, with steeper work near the river.
How do prairie soils affect walls?
Much of Post Falls sits on the Rathdrum Prairie, where glacial floods left deep deposits of gravel, cobbles and boulders. That coarse ground drains well, which helps walls, but excavation can mean digging through cobbles and rock. The same gravels hold the Spokane Valley-Rathdrum Prairie Aquifer, the area's sole-source drinking water supply, so drainage near fuel, chemicals or septic systems deserves care.
Who issues permits in Post Falls?
Post Falls has its own building department. Ask them about height thresholds and engineering before building a wall near 4 feet tall, or any wall that holds up a driveway, parking area or structure. Homes outside city limits fall under Kootenai County, which requires a site disturbance permit for most grading.
What do Post Falls wall projects usually involve?
- Grade-change walls between neighboring lots in new subdivisions
- Walls to level backyards and patios
- Steeper walls and terraces near the Spokane River
