Civil Engineering Stormwater Monitoring, CE1 Doug Ehlebracht Charlie Roberts Ethan Rogers Colton Freels Advisor: Aimee Navickis-Brasch Sponsor: Spokane County Liaison: Matt Zarecor
Bioinfiltration ponds are a common way to handle stormwater runoff, by filtration through vegetation as well as infiltrating the water through soil to the groundwater table. Spokane County has asked our team to develop a design to test the influent and effluent pollutant concentrations in order to determine the effectiveness of bioinfiltration ponds removing target pollutants. In Western Washington, the Department of Ecology requires municipalities to demonstrate that stormwater best management practices (BMPs), such as bioinfiltration ponds, are functioning to acceptable levels. This will be required in Eastern Washington in the near future and Spokane County would prefer to have preliminary monitoring systems in place before it is required.
Enté Creek Spawning, CE2 Thomas Scott Garrett Benson Mohamed Sambou Dallas Dimock Jamie Gable Advisor: Sue Niezgoda Sponsor: Spokane Tribe of Indians Liaisons: Casey Flanagan and Brian Crossley The Spokane Tribe of Indian Department of Natural Resources wants to construct a spawning channel for fall Kokanee Salmon spawning in Enté Creek. The current creek houses several degraded beaver dams which have filled in with sediment to create a swamp-like environment at the mouth of the creek. The beaver dams themselves present major fish passage barriers. In addition to the dams, the flow in the stream is too shallow for fish passage. We will conduct an analysis to determine the current ecological health of the stream, as well as all current barriers to fish passage. Streamline Solutions will then create a final design that the Spokane Tribe of Indians can implement to restore Kokanee Salmon spawning to Enté Creek. Gonzaga Design Exposition Day 2014
