Field Test of Living Snow Fences along Illinois Freeways
The objective of this study was to conduct field tests to provide insights on setback distances and species for future living snow fence (LSF) designs in IL. Seven LSF sites with different species and site configurations and their control sites were selected along Illinois freeways. All sites are within the right-of-way (ROW). Measurement grids and stakes were used to catch the snow accumulation pattern at each test site. Volumes of snow trapped by LSF sites and their control sites were calculated using the cross section method and compared using t-tests. Field measurement indicates that a major portion of the incoming snow was deposited near the snow fence in the downwind direction. The t-test results show that LSF sites trapped significantly higher volumes of snow than control sites without snow fences. The field tests evidenced that LSFs 3.7–6 m (12–20 ft) high with 30–55% porosity and an offset distance of 27.4–36.5 m (90–120 ft) within ROW of IL freeways are effective in trapping and depositing snow before it reaches the roads. Suitable species include Grey Dogwood, Indigo Bush, Staghorn Sumac, and American Plum.
