Tierra has acquired more than 550 residential and commercial properties parcels as an on-call provider for the Arizona Department of Transportation (ADOT). Tierra’s specific services to ADOT have included coordination and analysis of property titles; coordination of appraisals; and negotiations for acquisitions involving single and multi-family residences, mobile homes, businesses, and heavy industrial properties, including a cement plant. Uniform Act compliance is required on all ADOT projects.

Since 2014, Tierra has held an Indefinite Delivery/Indefinite Quantity (IDIQ) contract with the U.S. Department of Agriculture Forest Service to provide intensive and sample pedestrian archaeological surveys and cultural resources investigations on an on-call basis within Forest Service Region 3 in New Mexico.

As part of the clean-up process, a full inventory of cultural resources was requested.

Tierra is working with the Gila Valley Irrigation District (GVID) to obtain a new right of way grant on Bureau of Land Management (BLM) land in Graham County, Arizona. The project is necessary to allow for the repair of a diversion dam and canal headgate and for construction of a new access road for the GVID facilities located on the Gila River. The project requires intensive biological and cultural resources surveys, and will include Endangered Species Act Section 7 consultation with the U.S. Fish and Wildlife Service for potential impacts to Federally listed species. The project also involves managing the public involvement process and the preparation of a BLM-format Environmental Assessment.
