SUBSURFACE INVESTIGATION, SECTIONS E003 TO E005, GREENBELT ROUTE

Results are presented of 75 test boring made to study Alternatives 'A', 'B' and 'C' from Columbia Heights Station location near the intersection of 14th Street and Columbia Road N.W., extending northeast 3.5 miles to the District boundary of the Washington Metropolitan Area Metro system. The purpose of the exploration was to provide information for general plans studies relating to these several alternatives, which chiefly involve mined earth tunnels. The report contains logs of the test borings, results of laboratory tests on undisturbed samples, a continuous geological section along the line of METRO trackage for the various alternatives and comments regarding anticipated design and construction problems.
