Excavation in Leavenworth, WA

Leavenworth, Peshastin, Plain and Lake Wenatchee sit on some of the deepest loose ground in the state. The boulders mixed through it are what make jobs there hard.

Working ground in Leavenworth

What the ground is like

  • Glacial fill on Icicle Creek runs up to 300 feet deep. There’s no rock to hit, and there’s also nothing solid to shore against.
  • The moraines around Plain and Lake Wenatchee are studded with crystalline erratic boulders. Some of them decide where a driveway goes.
  • Two parcels a mile apart aren’t the same job. Clean outwash sand and gravel on the outwash plain, deep fine sand and silt in the old lake basins.
  • Valley walls above town run past 60 degrees, with documented landslide and debris flow paths. Access gets settled first.
  • Snow load and frozen ground move the calendar up here more than anywhere else we work. The county default is 57 psf at or below 950 feet and climbs from there.

Permits around Leavenworth

Inside city limits the City of Leavenworth handles permits. Peshastin, Plain and Lake Wenatchee go through Chelan County Community Development, and work near the rivers and lake brings in shoreline rules.

Questions

Leavenworth questions

Can you get a machine into a lot at Plain or Lake Wenatchee?

Usually, but the road in decides it. Send a photo of the driveway and the pitch and we’ll tell you what fits before anyone books a date.

Do you hit rock around Leavenworth?

Rarely. The fill is very deep. What you hit is boulders inside the fill, and that’s a different problem with a different price.
