Description:
Recently, the green infrastructure (GI) concept has been adopted by many cities for stormwater management even though doubt still remains as to whether it can be fully embedded into planning and design. As many researchers have stated, GI planning has been discussed as offering a number of broad benefits in ecological, economic, and social spheres. The aim of this study is to examine the benefits of GI which can be used at various ranges of scale to support the principles of low impact development (LID). Case studies of two different scales, site scale and neighborhood scale, have shown ecological, social, and economic benefits of GI. The projects include GI elements and LID strategies such as green roof, rain barrels, porous pavement, rain garden, gravel grass, vegetated swales, and retention basins. The result indicates that GI elements are effective in detaining stormwater and reducing the amount of runoff. Native prairie grasses, sedges, and plantings also improved habitat value and led to a noticeable increase in birds, bees, and butterflies. The GI project provided outdoor activities, promoted social interaction, and showed a positive effect on economic spheres as well. Quantification of these benefits is important for landscape architects, planners, and policy makers because it can provide better strategies for GI planning.
