Archaeological work conducted by Pape Dawson resumed within Crockett and Bonham Streets as part of the Phase I of the Alamo Plan. Much of the work that occurred over the past week consisted of the excavation of a utility trench along Bonham and Crockett, as well as the excavation of the location of a utility vault on Bonham.
Much of the trench work has encountered previously disturbed soils. In certain portions of Bonham and Crockett, the layer of asphalt measured approximate one foot in thickness. Trench depths reached up to a maximum depth of 10 feet below the surface. No significant artifacts have been encountered during the current work.
During the excavation of the utility vault on Bonham, soils encountered included dark clay in the upper 6.5 feet below the surface. At approximately 6.5 feet below the surface, the soil changed to a yellowish clay, often referred to in this area as Navarro Clay. This type of soil predates human occupation, and therefore indicates that it will not contain archaeological artifacts.
