Phase 3

Back to Project Overview

Project monitoring is essential to evaluating whether the Southern Flow Corridor-Landowner Preferred Alternative Project (SFC-LPA) has met the flood attenuation and ecological function goals. Only carefully targeted, science-based monitoring can provide the clear information needed to document project outcomes, provide accountability for the large public investment (over $10 million), and inform adaptive management, if needed.

Under the guidance of the Monitoring Advisory Committee, the Institute for Applied Ecology and Confederated Tribes of Siletz Indians developed an extensive monitoring plan. Monitoring will occur before and a minimum of six years after construction and evaluate the following parameters:  Vegetation, soils, groundwater levels, juvenile salmon use, flood levels, tidal hydrology, macroinvertebrates, water quality, channel morphology, and sediment deposition.
