Levees are critical to protecting some Arizona cities, towns and other communities from damaging floods. But the state has “orphan” levees that apparently no one is maintaining. It’s unclear whether many levees are being regularly inspected or even watched, which opens the potential for major flood damage in some areas, says Edward Kavazanjian, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, and a leading expert on geotechnical engineering for civil infrastructure systems. Similar concerns have been noted in the American Society of Civil Engineers Infrastructure Report Card.
