Broad Contour Levee

Broad contour levees's gentle slopes reduce erosion and wildlife burrowing

In order to reduce erosion and wildlife burrowing, the new levees will have 10:1 slopes instead of 3:1 slopes. Because these new levees will be broader and shallower than existing levees, floodwaters will be less likely to cause erosion during major flood events.
