Why are trees a problem near levees and floodwalls?
Tree roots that have grown into the levees provide pathways for seepage, especially when the trees are dead. Root balls of trees that are blown over during a storm can create critical voids in the levees. These voids can worsen seepage and weaken stability. Large overturned trees can fall on floodwalls and damage them. Corps guidance is clear: Woody vegetation in and near levees, berms and floodwalls is prohibited. 2. Why are fences a problem? Trees often become established along fence lines, especially volunteer trees like hackberries and tallows. Fence lines on the slope and along the toe of levees prevent proper levee inspections. Fences also hinder levee maintenance and flood-fighting activities. 3. What about the environmental and aesthetic values of trees?
