About this map

Galveston Island stretches across this coastal survey, showcasing the developed vacation and residential communities of Sea Isle, Terramar Beach, and Bay Harbor. These settlements are characterized by dense canal-front street grids such as San Jacinto Dr and Isla Del Sol, oriented toward the West Bay and the Gulf of Mexico. The map documents a complex aquatic landscape where the Intracoastal Waterway cuts through the bay, separating the barrier island from the mainland marshes and tidal flats of Brazoria and Galveston counties.

Ecological and navigational features dominate the surrounding waters, from the hazard of Carancahua Reef to the tidal openings of The Narrows and Amarada Cut. Numerous small landforms like Snake Island, Maggies Point, and Rattlesnake Mound appear amidst the wetlands, while the interior is defined by the winding paths of Halls Bayou and Carancahua Bayou. This 2016 record captures the modern infrastructure of FM 3005 connecting these remote island outposts.
