In preparation for downtown-area revitalization projects, Tierra was hired by the City of Tucson to survey, test, and excavate a property at the intersection of 6th and Toole Avenues within the Tucson Warehouse Historic District. Archaeological and archival research revealed that this parcel was first used as a distribution and storage center after 1880 when the railroad arrived in Tucson and represents early industry in the area. This project allowed researchers a unique window into industrial and commercial life in early Tucson. In partnership with the City, Tierra was able to complete the project in a timely manner while also furthering our understanding of the city’s rich heritage.

"It has been our pleasure to work with Tierra Right of Way this construction season. Their field staff is knowledgeable of construction, understand the balance of cultural sensitivity and keeping a project moving forward when possible, and work very well with the local Tribe. When the contractor encountered culturally sensitive artifacts, Tierra Right of Way staff expertly and timely communicated with the PUD, the Tribe and the State Department of Archaeology and Historic Preservation to resolve the situation while preserving the artifacts so that portion of the project could resume that same day. They met their scope and budget which were developed in conjunction with our contractor and were flexible in scheduling with our contractor. We are pleased to have Tierra Right of Way on our on-call archaeological services roster."
