The Pacific coastline at the far southwestern corner of the United States is defined by the international boundary between the United States of America and Mexico. This survey highlights the narrow coastal strip of Imperial Beach and the southern reach of Coronado, where land meets the Pacific Ocean and the inner waters of San Diego Bay. The map shows a transition from the dense residential grid of Imperial Beach—with streets like Palm Ave and Seacoast Dr—to the ecological wetlands of Oneonta Slough. The coastal geography is further shaped by the Silver Strand Blvd corridor and Emory Channel, while the presence of the N McCoy Trail and S McCoy Trail suggests managed access to the sensitive coastal environment near the border.
