About this map

Agricultural development and flood control infrastructure dominate this mid-century Rio Grande Valley landscape near the border of Cameron, Willacy, and Hidalgo counties. The settlements of Santa Rosa and Sebastian serve as local hubs, connected by the Southern Pacific and Missouri Pacific railroads. A complex network of water management features, including the North Floodway, Willacy Canal, and numerous elevated ditches, illustrates the region's reliance on managed irrigation for its citrus groves and fields.

Genealogists will find several burial sites preserved on the landscape, such as Guadalupe Cem, Santa Rita Cem, and El Azadon Cem. The rural road grid, including Cantu Road and Rabb Road, provides a clear view of the property divisions and infrastructure that supported the local farming economy. Landmarks like the Valley Acres Reservoir and various pumping stations further underscore the engineered nature of the South Texas terrain during this era of growth.
