Local conditions
Geotechnical conditions in Davis County
Davis County sits along the Wasatch Front where the transition from ancient Lake Bonneville lake-bed deposits in the lower elevations to colluvial and alluvial soils on the bench lands creates meaningful variability from one parcel to the next. That variability matters before a single footing is sized or a grading plan is finalized. Residential subdivisions climbing the benches, commercial development along the I-15 corridor, and public infrastructure projects throughout the county all depend on accurate subsurface characterization to avoid costly surprises during construction. Our geotechnical team, dispatched through our Salt Lake City regional hub, performs subsurface investigations, laboratory soils testing, and geotechnical reporting tailored to the conditions actually present on your site. From boring and sampling programs to bearing capacity analysis, settlement evaluation, and compaction specification, every deliverable is produced to support design decisions and satisfy Davis County and Utah agency submittal requirements.
The legacy of Lake Bonneville means low-lying areas in Davis County can contain compressible lacustrine silts and clays that require careful evaluation for settlement and bearing capacity before structure loads are applied. Seasonal freeze-thaw cycles and spring snowmelt also influence grading schedules and the timing of field investigations, particularly for projects at higher bench elevations.
FAQ · Davis County
What soil conditions are commonly encountered on the Wasatch Front bench lands in Davis County, and how do they affect foundation design?
Bench areas typically contain alluvial and colluvial soils with variable gravel, sand, and silt content. Density and bearing capacity can shift significantly over short distances. A boring and sampling program evaluated through ASTM D1586 (Standard Penetration Test) or ASTM D2113 core sampling gives designers defensible bearing values rather than assumptions, reducing the risk of over- or under-designed foundations.
How does expansive or collapsible soil potential factor into a geotechnical investigation for a Davis County project?
Soils derived from fine-grained lake deposits or weathered bench materials can exhibit swell or collapse behavior when moisture conditions change. Laboratory index testing—including ASTM D4829 for swell potential and ASTM D5333 for collapse potential—is used to screen samples. Results directly influence slab design, subgrade treatment recommendations, and drainage detailing to protect long-term structural performance.
Davis County experiences seismic activity associated with the Wasatch Fault. What seismic-related geotechnical work is typically required?
IBC Section 1613 and ASCE 7 require Site Class determination based on subsurface shear-wave velocity or Standard Penetration Test data. For sites near active fault traces, liquefaction susceptibility screening of saturated granular soils is also standard practice. Our geotechnical report addresses Site Class assignment and, where warranted, includes a liquefaction analysis consistent with the project's governing building code cycle.
