An ambitious project to improve the levee system around Marysville has had one unintended consequence: street flooding in parts of East Marysville. On Tuesday, the Yuba Water Agency Board of Directors will consider approving a $713,000 grant to the City of Marysville to replace high flow pumps at the East 17th detention basin near Highway 20. Beginning in 2023, the detention basin has filled during high intensity rain events, and flooded some of the surrounding streets because the pumps are no longer large enough to drain the detention basin. According to a staff report for Tuesday’s meeting, the flooding is directly related to the multi-million dollar 7.6 mile long Marysville Ring Levee project, which the U.S. Army Corps of Engineers launched in 2010.
