To build water-efficient cities, water managers and urban planners must coordinate better

For improved water efficiency in cities, water managers and urban planners must coordinate their efforts better, according to a new report led by University of Arizona landscape architecture and planning researchers.

Lack of time and resources and practitioners not in the habit of working together were cited as the main factors stymieing better collaboration, according to responses to a national survey of water managers and urban planners. The report includes a tool for practitioners to identify goals for collaboration and what barriers might stand in their way.

The first steps toward improved collaboration include joint training sessions where water managers and urban planners hear each other's challenges and brainstorm ways of coordinating their work. Where coordination works well, a water engineer might sit in on development review meetings for new projects and weigh in during permitting to ensure that the new development would achieve groundwater and stormwater goals of regional and state agencies.

In the future, water managers and urban planners could help staff each other's agencies for a complete integration of the two functions.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
