context_section_description: Rancho Cucamonga's location at the base of the San Gabriel Mountains has necessitated the use of numerous control channels and basins to reduce the seasonal flood danger from the several streams descending from the range. In past years, some of the city's roads were known for flooding. Hermosa Avenue, in particular, now features many high curbs and extra-large storm drain grates to reduce flooding.
