The international border between the United States of America and Mexico bisects this desert landscape, where the agricultural flats of the Yuma Valley meet the expanding urban grid of San Luis. This 2014 survey captures the precise street network of this border community during a period of significant growth, showing residential and commercial blocks reaching toward the limit of Yuma County. The map reveals a densely planned townsite defined by thoroughfares such as N Cesar Chavez St and E Juan Sanchez Blvd, illustrating how political boundaries and irrigation-fed agriculture shape the development patterns of the Arizona-Sonora frontier.
