About this file
This document is a supplemental geotechnical report for a retaining wall design related to a federal contract opportunity.
The report provides recommended retaining wall parameters for the planned construction of a stanchion barn and cattle working barn at a facility in Kerrville, Texas. The parameters cover soil properties such as friction angle, equivalent fluid density, and unit weight for various soil formations including clayey gravel, lean clay, limestone, and select fill. This information is necessary for the design and construction of the concrete retaining walls that are part of the facility improvements. The report was prepared by Arias Geoprofessionals, Inc. for the USDA Agricultural Research Service project.

Retaining wall recommendations were not within the scope of work for the above referenced Report.
Concrete retaining walls are now planned as part of the improvement and expansion of the facility, and recommended retaining wall parameters for the site are provided below in Table 1. The parameters presented for the Select Fill is an assumed value, since we do not know what the Select FilIwill be ultimately utilized at the site
