Variable General Info
Vegetation type ?Comment:Short grass, tall herbaceous plants, deciduous trees. There are three types of green roofs in Chicago: extensive green roofs, intensive green roofs, and semi intensive green roofs. Extensive green roofs are plantewith low height and slow growing plants. Intensive green roofs consist of large perennial herbaceous plants and, occasionally, shrubs and smatrees. The semi-intensive green roof is a mixture of extensive and intensive green roof with 25% or less of the area as extensive green roof. |
