“Oceana’s Eleven” Oceana County Road Commission Grant – Funded crossing replacements
Oceana County Road Commission (OCRC) In Partnership with the White River Watershed Task Force
Road Commission personnel are wise to become educated about the damage caused to hydrologic ecosystems by storm water runoff, sedimentation, stream and road bank blow-outs, roadway undermining and collapse, all as a result of undersized culvert design and installation.
During high-water events, a culvert acts like a rifle barrel and the water moving through it becomes the bullet. Because of this, engineers should be proactive in thinking about the system as a whole, and go “bottomless” when designing road crossing replacements.
Streams and rivers are roads and highways for aquatic and non-aquatic life. • “Bottomless” and “right-sized” crossings maintain connectivity, allowing fish and wildlife to move freely and seek out resources necessary for survival.
