I thought that this article was timely. Entitled "Green Streets Pave the Way to Greener Communities" By Jason A. King, ASLA, and Shawn Kummer, it talks about two street projects in Portland and how "green" cuts across many areas of concern, it's not necessarily easy or quick, but it can respond to a wide variety of needs.
"Stormwater runoff flows downhill along the existing street curb until it reaches the first of four stormwater planters. A 12-inch curb cut channels the street runoff into the first stormwater planter. Once inside the planter, the water is allowed to collect until it reaches a depth of six inches.

If a rain event is intense enough, water will exit through the planter’s second curb cut, flow back out into the street and eventually enter the next downstream stormwater planter."
