Palo Alto's horizontal levee passes test, reduces flooding during storms
"So, with this storm surge and the King tide event, it was a great opportunity for us to test this out. So, we came out here and we were able to further document and see how well it performed. So, we got to see that the king tide came up very close to where the pathway is behind you, and it did what it's supposed to do,"
"And that king tide came through here and it came up to the edge of the berm,"
Recent storms and king tides surged into a quiet marsh behind the Palo Alto wastewater treatment plant and flowed onto a newly constructed horizontal levee. The levee uses an angled, gently sloped design to absorb tidal energy and release water rather than holding it back, protecting infrastructure while reducing destructive wave impacts. City engineers documented high-water marks with photographs and timelapse video during the king tide, confirming expected performance. Volunteers from Save the Bay planted hundreds of native shrubs across the levee, creating habitat and advancing a nature-based approach to sea-level rise and flood resilience.
