Green roofs are an ideal technology for sites without significant space at ground level for [[infiltration]] and zero-lot line projects with outdoor amenity requirements. Green roofs are typically [[Green roof construction|sized]] based on the available roof area, as opposed to treatment volume requirements. Green roofs are feasible in most greenfield development situations, but should be planned at the time of building design. <br>
