Completed on October 15, the pavilion was contructed over the summer of 2005 in honour of the District of Metchosin’s 20th anniversary. The green roof was meant to demonstrate the principle of District of Metchosin Bylaw 467, which is meant to mitigate rainwater run-off.

Paradise Cityscapes, a local landscaping and green roofing company, offered to install the green roof at no charge to the municipality. The 12′ x 16′ roof had already been waterproofed with two-ply Torch-On. On top of that was placed JDRain, a drainage composite donated by Nilex (an adhesive was used to secure the membrane to the roof). This product contains small reservoirs which will trap rainwater and irrigate the plants when they need it. After placing a 2′ strip of drain rock along the top of the roof and a 6″ strip near the bottom, we covered the roof with a 5″ layer of black pumice and organic compost (70% pumice, 30% compost).Into this we planted nearly 100 native plants: satinflowers, Olsynium douglasii and Sisyrinchium angustifolium; long-stoloned sedge (Carex inops); Calf oatgrass (Danthonia californica); 5-6″ Roemer’s fescue (Festuca roemeri); nodding onion (Allium cernuum); 6 lance-leaved stonecrop (Sedum lanceolatum); spreading stonecrop (Sedum divergens); broad-leaved stonecrop (Sedum spathulifolium); thrift or sea-pink (Armeria maritima); assorted mosses; Wallace’s selaginella (Selaginella wallacei); yerba buena (Satureja douglasii); Sea blush (Plectris congesta); clarkia (Clarkia amoena); springold (Lomatium utriculatum); death camas (Zygadenus venenosus); and common camas (Cammasia quamash) seeds.We hope to eventually add a flow metre to the drain pipe, which will empty into a rain barrel, to see how much water the roof retains. Other than occasional weeding, the maintenance on the roof should be minimal. With a work crew of 8 people, we completed the project in 5 1/2 hours.
