Narrative |
| Green roof:
Installed in 2004, this roof garden constitutes 16% of the total roof area (about 900 square feet). The roof consists of soils, crushed granite, pygmy bamboos, and amur maples surrounded by birch mulch (which protects the plat roots from cold and prevents moisture from evaporating). It is 70% stone, sand and gravel and 30% plants. The perimeter of the roof is extensive, with a shallow (6-inch) soil profile (which then drops down four feet), while the center of the roof is intensive, deep enough to allow for the tree planting.
There are two drains- a primary one and a back-up, while the remaining water is filtered through the gravel. The trees are Redbuds, and ivy was also planted. The four-foot growing mix added enough weight to require special structural solutions on the building. Maintenance is minimal, and limited to pruning. There is no deweeding, irrigation, or fertilizing required, and the FMO checks the drainage system regularly.
