The international border between the United States of America and Mexico anchors the southern edge of this coastal survey, where the Pacific coastline meets the protected wetlands of the Tijuana Slough National Wildlife Refuge. The map details the residential grid of Imperial Beach, showing street-level alignments from Palm Ave down to Ebony Ave. North of the town center, the narrow coastal landform supports the Silver Strand State Beach Trail and Bayshore Bikeway Trail, tracing the thin strip of land separating the open Pacific Ocean from the quiet waters of San Diego Bay and the Emory Channel. The spatial arrangement highlights the critical transition from urban development to the tidal ecosystems of Oneonta Slough, providing a precise look at the modern shoreline and maritime boundaries near Coronado.
