What does a structural engineer look at in Jefferson County?

Jefferson County is hilly, with shallow rock and steep lots, and a mix of older river-town houses and newer homes on acreage. Engineering questions here often involve walkout basements, retaining walls, and houses built into a slope.

What is different here

  • Sloped lots. Tall downhill foundation walls and soil pressure on the uphill side.
  • Rock near the surface. Footings that step, and parts of one house bearing on different ground.
  • Older river towns. Festus, Crystal City, and De Soto have brick and frame houses a century old.
  • Manufactured homes. Common on rural lots, where a lender may ask for a foundation certification.
