Streets in a number of locations in Scottsdale are subject to flooding, and in some cases closure, during severe storm events which necessitates the use of alternative transportation routes. Residents of the city are encouraged to be aware of street locations of potential flooding or closure and to determine alternate routes to be used in times of flooding. The maps below show locations of potential street flooding or closures to assist in this effort. These maps should be used in conjunction with street maps to determine potential alternate transportation routes.
