About this file
These are geotechnical drilling logs from a series of vibracore soil borings conducted in the Wilmington Inner Ocean Bar area in 2012, documenting detailed subsurface soil classifications and characteristics. The logs contain 15 different borehole designations (WH12-V-1 through WH12-V-15), with each boring log providing comprehensive information including location coordinates, drilling dates, soil classifications, and depth-specific soil descriptions using the Unified Soil Classification System. Predominant soil types include poorly graded sand (SP), clayey sand (SC), lean clay (CL), and silty sand (SM), with most samples showing light gray to dark gray coloration and varying percentages of shell fragments ranging from trace amounts to approximately 34% shell content.
The soil samples were systematically collected at depths typically ranging from 22 to 59 feet below mean lower low water (MLLW), with detailed grain size distribution analyses performed for each sample. Laboratory testing included visual shell content assessments, sieve analyses, and classification according to standard geotechnical protocols. The comprehensive documentation suggests these logs were likely generated to support geotechnical investigations for a potential marine or coastal engineering project, potentially related to the maintenance dredging of the Wilmington Harbor Inner Ocean Bar, as referenced in the associated federal contract opportunity for the U.S. Army Corps of Engineers Wilmington District.
