Slope Stability and Landslide Assessment
Evaluation of slopes, landslides and erosion threatening homes, roads or development, with stabilization design.
What the work involves
Engineers evaluate slope geometry, soils, groundwater and movement history, run stability analyses, and design fixes such as drainage, regrading, retaining structures, soil nails or vegetation. Landslides are often triggered by water, so drainage is central. In some states an engineering geologist is also required.
Local conditions we plan for
- Expansive clay soils and foundation movement
- Hurricanes and coastal flooding on the Gulf Coast
- Flash flooding (Hill Country, Houston)
- Karst in the Edwards Aquifer region
Building code: 2012 IBC/IRC listed at the state level; local jurisdictions may adopt newer editions (ICC adoption chart, April 2026).
When you need it
- Cracks at the top of a slope or bulging at the toe
- Leaning trees, fences or walls on a hillside
- Slide after heavy rain
- Building near the top or bottom of a slope
Frequently asked questions
How much does slope Stability and Landslide Assessment cost?
Across the US, slope Stability and Landslide Assessment usually costs $3,000 to $30,000. Estimate. Small residential assessments are at the low end; instrumented landslide investigations are higher.
How long does slope Stability and Landslide Assessment take?
Plan on 3 to 12 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Do I need a licensed PE for slope Stability and Landslide Assessment?
In most US jurisdictions, yes. When the work needs a permit, the plans, calculations or report usually must be sealed by a Professional Engineer licensed in the state where the project is located. Every deliverable we issue for permit is sealed that way.
How do I verify an engineer's license in Texas?
Engineers practicing in Texas are licensed by the Texas Board of Professional Engineers and Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
Which building code applies in Texas?
2012 IBC/IRC listed at the state level; local jurisdictions may adopt newer editions (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
What site problems do engineers see most in Texas?
Common issues include expansive clay soils and foundation movement, hurricanes and coastal flooding on the Gulf Coast, flash flooding (Hill Country, Houston) and karst in the Edwards Aquifer region.
