Adair Village Environmental Support
In the early 1940s a large area of Adair Village, Oregon was used as a military training facility, and later a prisoner of war camp in support of the war effort. At its height the camp supported 30,000 people, but it was only in operation for a few years. The camp, which was really a […]
Point Defiance Waterfront Phase I Redevelopment
With miles of hiking trails, scenic shorelines and panoramic views of Commencement Bay, Point Defiance Park is one of Tacoma’s finest natural attractions. But a portion of the park near the entrance had been underutilized for years. Metro Parks Tacoma (MPT) envisioned the full potential of this premiere waterfront property, and in 2014 Tacoma voters […]
Big Wood River Bridge
The Idaho Transportation Department (ITD) needed to upgrade the SH-75 bridge over the Big Wood River. The aging two-lane bridge located just outside Sun Valley, Idaho, was too small to accommodate ITD’s road-widening plans. ITD hired GeoEngineers to complete subsurface investigations and make geotechnical design recommendations for retaining walls adjacent to the new bridge and […]
Well Replacement for Eastern State Hospital
Eastern State Hospital is a 287-bed inpatient psychiatric hospital in Medical Lake, Washington, and one of just two state-owned adult psychiatric hospitals.

Water levels in both wells were declining, and one of […]
Groundwater Well Replacement for Vera Water District
Vera Water and Power District operates a water system in Spokane Valley, Washington which consists of high-yield production wells at nine single- or multiple-well sites. One of Vera’s wells failed, and in response, Vera hired GeoEngineers to evaluate five alternatives to augment their water supply by a minimum of 3,000 gpm. Once the team identified […]
U.S. Fish and Wildlife Service Hatchery Debris Cleanup
In 2006, a United States Fish and Wildlife Service (USFWS) contractor demolished a fish hatchery building near Hagerman, Idaho and disposed of wood and concrete debris in a nearby ravine instead of a permitted landfill. The fish hatchery debris (known to contain lead paint) was commingled with debris from other demolition projects and abandoned in […]
Walla Walla River Enhancement Designs
Before this project, the 1.5 miles of the Walla Walla River southeast of Lowden, Washington, was far from ideal fish habitat. The reach had a deeply incised channel, confining levees, and other agriculture-related impacts making fish habitat almost non-existent. In 2013 the Tri-State Steelheaders (TSS), a non-profit fisheries enhancement group, hired GeoEngineers to design new […]
