I had someone ask me this question recently and it made me run around town to take some more pictures. LID that has been designed intentially to improve stormwater quality or affect stormwater quantity is not easy to find. What is more common are aesthetic landscaping features that accomplish this task. One example is canopy cover. Tulsa has long reaching goals for canopy cover and recovery/replacement of trees lost in 2007's ice storm. A great side effect is that canopy cover, when trees are in leaf, significantly reduces stormwater runoff. The effect is huge compared to areas of pavement. Some common examples are trees planted in medians, which only achieve the desired effect when they overhang roadways and sidewalks. Here are some local examples:
But there are places that go above and beyond when placing trees. One of my favorites is the area surrounding One and Two Warren Place, at 61st and Yale. The roadway to the right is one example. They have included a mix of deciduous trees (median, right of photo) which affect stormwater runoff during parts of the year, and also evergreens, which achieve the same effect year round. And if you have the chance to visit, take a look behind One Warren Place (1st photo above) and see the surface parking. The plantings could make you forget you were in an urban setting, and are a far cry from the standard surface parking you would see downtown, or anywhere else for that matter.
