Tailing minimizes the light and presence within the water, which may interfere with the distribution as well as foraging abilities of certain types. The debris surrounding seawalls has a tendency to have much less favorable physical buildings (Higher calcification levels, much less architectural company of crystalline framework, low silicon material, and much less macroscale roughness) when contrasted to all-natural coastlines, which can offer issues for types that stay on the seafloor.


Lack of maintenance is also a major issue with seawalls. In 2013, greater than 5,000 feet (1,500 m) of seawall was found to be collapsing in Punta Gorda, Florida.
