Arboriculture, bios wale, conservation corridor, Eco roof, green walls, heat island, infrastructure, parks, porous paving, retaining wall, vegetation Cities are a complex interaction of the natural and built elements. In order to maintain some degree of balance in the natural systems, we have to introduce engineered systems to create and transport energy, to remove and process wastes, to control storm runoff, etc
