La Playa Stadium Turf Replacement at Santa Barbara City College

Santa Barbara City College
Santa Barbara, California

Project Summary

The purpose of the geotechnical study that led to this report was to analyze the soil conditions at the project site and to provide geotechnical recommendations for construction.  The soil conditions include surface and subsurface soil types, expansion potential, soil strength, settlement potential, bearing capacity, and the presence or absence of subsurface water.   The scope of work included:

Scope of Work

  • Performing a reconnaissance of the project site.
  • Hand augering, sampling, and logging four borings to study soil and groundwater conditions. 
  • Laboratory testing soil samples obtained during the subsurface exploration to determine their physical and engineering properties.
  • Consulting with owner representatives and design professionals.
  • Analyzing the geotechnical data obtained.

Regional Geology

The site lies within the Santa Barbara alluvial plain in the western portion of the Transverse Ranges geologic province.  Numerous east-west trending folds and reverse faults indicative of active north-south transpressional tectonics characterize the region. The ongoing regional compression produces the east-west trending faults that deform early Pleistocene- to Tertiary-aged marine and non-marine sedimentary bedrock units.  These sedimentary bedrock units underlie the property at unknown depths.
