About this file

This document provides boring logs from geotechnical investigations for the L385 Levee Rehabilitation and Relief Wells project. The boring logs detail soil stratigraphy, composition, and engineering properties at sample depths for pilot holes drilled along the levee. Information recorded includes blow counts, moisture content, Unified Soil Classification System symbols, grain size distributions, and other field observations. The project is located along the Missouri River Levee System in Levee District L385. The boring logs will inform design and construction methods for the levee rehabilitation and installation of relief wells to control seepage.
