Background:

Tetra Tech assisted CREST with the planning and design of a tidal wetland restoration project at Karlson Island, in the Columbia River. The project was designed to target the NOAA Estuary Module limiting factors by improving off-channel habitat access for salmonids and food web connectivity. Initial investigation of the project included developing a 2D hydraulic model to simulate water surface elevations, velocities, and flows at various tide levels for existing and alternative conditions. Various restoration alternatives were developed and analyzed resulting in the selection of a preferred alternative that met the project objectives and budget. The selected alternative was carried though to final design where Tetra Tech developed a full design plan set, construction technical specifications, bid sheets, and a project budget. Engineering support during construction was also provided by Tetra Tech.
