Emigration Creek Restoration By: Aaron Rees, Nikolai Narvestad, Tiana Cerciello, Kade Tang

Emigration Creek Overview The Emigration Creek Watershed covers about 17 sq. miles. 1/8 mile through Westminster Campus. 40% owned privately, 33% owned by Salt Lake, and 27% is National Forest land Emigration Creek serves great purpose to its surrounding area in Salt Lake and Sugarhouse by providing a source of water and minerals within the watershed. The watershed is responsible for maintaining a viable cyclical system of energy in order for life to be sustainable.

Issues Erosion: banks are steeply eroded compromising the safety of nearby structures along with the health of the ecosystem. Pollution: ineffective storm drains from parking lot pollutants into creek causing potential eutrophication and posing threats to both vegetation and macroinvertebrate populations. Littering: build up of debris and trash throughout branches and low-depth areas.

Bank Stabilization Bank Shaping Planting Vegetation Brush Mattress Re-grading streambanks to a stable slope Planting Vegetation Placing topsoil and other materials needed for sustaining plant growth, and selecting, installing and establishing appropriate species. Brush Mattress Combination of live stakes, live fascines, and branch cuttings installed to cover and physically protect streambanks, eventually to sprout and establish numerous individual plants. Dormant Post Plantings Planting of cottonwood, willow, poplar, or other species embedded vertically into streambanks to increase channel roughness, reduce flow velocities near the slope face, and trap sediment.

Trench Drainage System Install a shallow basin drainage system, which runs over a long distance. Designed to collect and divert water at a lower and more appropriate location to avoid contamination of the creek.

Macroinvertebrates Hire biologist to interpret the data we collected on macroinvertebrate richness and determine which species of macros should be supplemented to the current ecosystem and in what quantities.

Decrease Human Disturbance Signage: several professional looking signs around the creek area will remind students, staff, and other foot traffic that the creek is in a fragile state and should be respected and kept clean. Fencing: certain areas near high erosion transects will be fenced off and access to public will be restricted in order to give the bank stabilization process adequate time to be effective. Posters: the remaining budget will be spent on creative laminated posters to put around campus and the sugarhouse area urging people to take care of the creek. Additionally, the posters will contain information regarding bi-monthly volunteer times to keep the creek in good health.
