About this map

Portland sits at the northern terminus of the Causeway in this coastal Texas survey, marking a period of suburban expansion across the San Patricio and Nueces county lines. The landscape is dominated by the vast waters of Corpus Christi Bay and Nueces Bay, where maritime activity and resource extraction define the local economy. A complex network of navigational aids including Range Lights and various Light markers guides traffic through the Corpus Christi Channel, while the surrounding shallows are home to extensive oyster beds and geological formations like Long Reef, Donnel Reef, and Alta Vista Reef. Onshore, the development around Sunset Lake and Indian Point reveals the town's growth toward the shoreline, punctuated by numerous Gas Wells and Oil Wells that signal the region's industrial importance during the late 1960s and 1970s.
