Tree hydration system made from recycled diaper material minimizes stormwater runoff

Using watering bags to nurture young trees can help ensure a moist soil environment as the plants develop root structure. But standard watering bags require constant refills, and do little to deter stormwater runoff pollution. However, a new product made from the same material used in disposable diapers can catch and retain rainwater before releasing […]

Telescopic walls could rise on demand to stop flood waters

A University at Buffalo (UB; N.Y.) Ph.D. student has created what he hopes become “rise on-demand” flood walls. Jorge Cueto devised a patent-pending system of telescoping rectangular fiber-reinforced concrete boxes. The walls can be installed below ground level, to avoid blocking any water views, and can be raised when the threat of flooding occurs. Cueto […]

Urban design software matches abandoned land parcels to green infrastructure projects

When Nicholas de Monchaux, an associate professor of architecture and urban design at the University of California, Berkeley, began his “Local Code” project almost 7 years ago, he set out to address two of the most pressing problems facing modern cities. Local Code uses open-source software to match thousands of abandoned city lots with site-specific […]
