TREMAINE & ASSOCIATES, INC is a cultural resources management firm, established in 1994, and headquartered in West Sacramento, California.

Our services include feasibility studies, management plans, archaeological reconnaissance, site testing, mitigation, and monitoring. In addition to conventional methods, we are also able to offer our clients more innovative solutions through non-invasive geophysical technology. We survey underground conditions using a host of geophysical tools, including our own Discover™, to reveal subsurface conditions before your project begins, avoiding costly delays during construction due to unanticipated discoveries.

TREMAINE has successfully completed a wide range of projects, from small-scale, local land development to highly complex and demanding programs in the sectors of communications, civil engineering, transportation, water resources, and military facilities, from our home here in the Sacramento Valley to locations as remote as the Giza Plateau in Egypt.
