The Nueces River valley defines the southern boundary of San Patricio County, creating a complex wetland environment where landforms like Odem Island and Griffin Island emerge from the delta marshes. North of the river, the landscape transitions into a grid of agricultural lands and rural corridors anchored by the settlements of Edroy and Hubert. This 2016 survey shows the concentration of residential development at Edroy Colonia, situated just east of the Edroy Cem.
