About this map

Port Isabel serves as the focal point of this coastal survey, where the mainland meets the vast Laguna Madre and the Gulf of Mexico. The town's layout is defined by its relationship to the sea, featuring the Port Isabel Channel and the Port Isabel Side Channel which facilitate maritime industry. To the west, Laguna Heights overlooks the wetlands of Vadia Ancha, while the Queen Isabella Causeway provides a critical link across the water to the southern tip of Padre Island.

The landscape south of the city is a complex network of small hills known as lomas, such as Loma del Mesquite and Loma de la Draga, rising above the tidal flats. These features, along with the Brownsville Ship Channel, reflect the unique estuarine environment of South Bay. For those researching local heritage, the map identifies the Port Isabel City Cem and Santa Isabel Cem, preserving the history of this maritime community.
