The Imperial Beach Municipal Pier extends from the California coastline into the Pacific Ocean, serving as a prominent landmark on this 2012 survey. The coastal interface is defined by the transition from the built environment of Imperial Beach to the tidal wetlands of the Oneonta Slough to the south. This map details the westernmost residential and recreational edge of the community, where streets like Palm Ave, Seacoast Dr, and Calla Ave terminate near the sand. The layout illustrates the urban planning of a modern seaside town, highlighting the proximity between the residential blocks and the sensitive coastal ecosystems of the slough. This specific sheet focuses on the offshore waters and the immediate littoral zone, capturing the infrastructure that connects the land to the sea just north of the international boundary.
