As living and working in walkable urban centers becomes more popular, interest has risen in such projects, which are often called deck parks.

It now draws crowds for food trucks, a reading area, a playground and free concerts.
Since then, dozens of deck parks have been proposed in about 30 cities including Philadelphia, Denver and Los Angeles, said James Burnett, a landscape architect whose firm works on many such plans, including two in Atlanta.
