The enhancement of seawalls near aquatic environments can cause raised tailing impacts in the waters surrounding the seawall. Shadowing minimizes the light and visibility within the water, which might interrupt the circulation in addition to foraging abilities of certain types. The sediment bordering seawalls has a tendency to have less positive physical homes (Higher calcification levels, much less architectural organization of crystalline structure, reduced silicon material, and less macroscale roughness) when compared to all-natural coastlines, which can present issues for types that live on the seafloor.

Absence of maintenance is likewise a significant concern with seawalls. In 2013, greater than 5,000 feet (1,500 m) of seawall was located to be collapsing in Punta Gorda, Florida.
