A gray morning today for the ribbon cutting atop the Bonneville Power Administration 905 Building Green Roof, with some special guests, including BPA Executive Vice President of Internal Business Services Kim Leathley and Regional Administrator of GSA Northwest/Arctic Region George Northcroft, who did the official ribbon-cutting with selected guests.
The project is nearly complete with a few odds and ends to finish, including final adjustments to the irrigation, and some supplemental cuttings to fill in some areas. For the most part, everything looks great, and the sedum cuttings are starting to take root and spread.
We also got a sneak peek at the rainwater tanks in the basement, which is providing irrigation to all of the rooftops during the dry portion of our summer. The project will have 36,000 gallon capacity, which will provide 100% of irrigation demand for the green roofs.
