The fence will be a minimum of four feet tall and should be sufficient to keep people out. However, there really is nothing that can stop a determined fisherman, except calling the police. DWU will look into the possibility of a pier, but it would have to withstand high water velocities. There were several questions as to why trees in the dike create a flood hazard and why they need to be removed. Roots of trees are perfect conduits for the water.
Water follows the roots through the dirt, which causes erosion around the roots.
There will be grass on the dike, and DWU will replace some trees in an area that won't compromise the integrity of the dike. A 200 to 300 year flood could break Dike 2, which is at elevation 453 feet mean sea level. Some trees are not protected by laws or ordinances administered by the City Arborist. The maximum grade will be eight percent in accordance with ADA standards. It is highly eroded and rough.
