Lower Borrego Valley is defined by a sparse desert grid where the arid flats meet the rising slopes of the Vallecito Mountains and Fish Creek Mountains. A small settlement pattern is visible in the northwest, centered on Main St and Broadway, with numbered streets and alphabetical avenues including A St and F St creating a tiny pocket of urbanization amidst the desert floor. This 2018 survey reveals the critical role of ephemeral water systems like Alma Wash and San Felipe Creek in shaping the geography of the San Diego and Imperial county line.
