Case studies - Living Roofs in Integrated Urban Water Systems - page 160

are being carried out to maximize the stormwater management optimization
of not only the rain garden, but also other areas of the whole site.
F Living roofs, of two different sizes:
1 A 1,300 m 2 extensive living roof on the seniors' residence. This roof has
100 mm of growing media and is planted with a mix of herbs and succu-
lent species. The living roof has even greater ecological value in that it also
houses photovoltaic panels for supplying electricity to the building.
2 Six extensive roofs on the complex of 14 townhouses. All non-vegetated
roof area surface low and the occasional vegetated roof overlow are
diverted to rainwater leaders that drain to low-through planters at grade.
Overlow from the planters in turn lows into the creek. While the design
of the living roof of the seniors' residence has little to no visual value from
grade, as it is extensive with a modest parapet, the living roofs on the
Dolph Creek Townhomes are visible from above from the neighboring
apartment buildings and seniors' housing facility.
