Avra Valley defines this portion of the Sonoran landscape, where the flat basin floor begins a gradual rise toward the southern mountains. The map captures a residential pattern characterized by long, straight thoroughfares and localized clusters of named streets that reflect modern land division in Pima County. While much of the area remains open, development is concentrated along the western corridor near S Marstellar Rd and S Sandario Rd.
