This document is a Subsurface Exploration Records report for Project P1555U Wallace Creek Service Road Realignment located at MCB Camp Lejeune in Jacksonville, North Carolina. The report was prepared for Naval Facilities Engineering Systems Command (NAVFAC) Mid-Atlantic and is dated 06/16/2026. The exploration records include geotechnical boring data, laboratory test results, geophysical survey findings, and soil classification information based on the Unified Soils Classification System. The document contains six geotechnical boring reports with detailed stratigraphic logs, analytical laboratory results for metals and nutrients (including phosphorus, potassium, and calcium levels), and geotechnical testing data such as grain size analysis, Atterberg limits, and moisture content determinations. Geophysical survey results from a ground-penetrating radar investigation are provided identifying subsurface anomalies and former building locations.

The technical findings document site conditions along the proposed road realignment corridor, including soil composition, groundwater levels, and potential subsurface obstacles. Laboratory testing was performed by Catlin Geotechnical Laboratory and analytical testing by an external laboratory using standard methods (ASTM D1557-91, D4318, D2974). The report includes site maps with local grid coordinates, testing location plans, a cross-section layout, and comprehensive boring legends explaining soil symbols, abbreviations, and classification criteria. This exploration record serves as baseline geotechnical information for the design and construction planning of the Wallace Creek Service Road realignment project at the military installation.
