SUBSURFACE INVESTIGATION, SECTION E001, GREENBELT ROUTE

Results are summarized of four supplementary test borings made in Section E001 of Greenbelt Route of the Washington Metropolitan Area Metro system near the Intersection of Florida Avenue with U Street N.W. in downtown Washington, D.C. The purpose of the exploration was to obtain additional information on the position and irregularities in the surface of decomposed rock and bedrock which is near to METRO tunnel openings. The report contains a revised geological section incorporating the borings, logs of the test borings, results of laboratory identification testing and comments on the possible character of the materials to be intersected by the tunnels. The work supplements Report No. MRWJ-74-107 which summarized previous exploration in Section E001.
