Waterfront structures are buildings and facilities located along the edges of bodies of water, such as rivers, lakes, and oceans. These structures can include docks, piers, marinas, and waterfront parks, designed to enhance access to water and support recreational activities. They often serve both functional and aesthetic purposes, providing spaces for boating, fishing, and leisure. In addition to recreational uses, waterfront structures can also support commercial activities, such as restaurants and shops. They are often designed to withstand environmental factors like waves, tides, and flooding, ensuring safety and durability. Examples of waterfront structures include the Sydney Opera House and the San Francisco Pier 39.
