Stalking decreases the light and visibility within the water, which might interfere with the circulation along with foraging capabilities of particular species. The sediment surrounding seawalls tends to have less beneficial physical properties (Higher calcification degrees, less structural organization of crystalline structure, reduced silicon web content, and less macroscale roughness) when contrasted to natural shorelines, which can present problems for types that reside on the seafloor.

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

In contrast, the seawalls likewise acted in a negative way to catch water and delay its resort.
