So we like to think we have some great green roofs and walls here in Brighton. Well, we do – but there are lessons we can learn from others including the good citizens of Olympia WA, San Francisco CA and Portland OR.
I was lucky enough to visit this summer – here are some pictures that I hope act as inspiration. We could think, and act, so much bigger.
In the Government complex at Olympia, Washington, is a large area of green roof established on underground car parks. Food is grown for local food banks, tended by Government workers. Some lovely large squash ripening in the sun. There is a large area of wildflower mix (‘Ecolawn’) sown for insects and appearance, and is not watered. This has been established by the Department of Enterprise Services – basically the legal and procurement department!
Nearby, just outside the historic Capitol building, is an area of rain gardens that have been retrofitted to help manage storm water. They are very attractive, and feature seating to encourage enjoyment.
San Francisco Academy of Sciences has a living roof…that is so large it is a visitor attraction in its own right. Not a very good photo, so I’ve stolen one from the website and there are more here.
Also in San Francisco were these mini gardens, usually in shopping areas, that brought planting into very urban settings, softened the street scene and provided fun features and places to relax. A ‘public parklet’ indeed!
Portland, Oregon is well known for its approach to sustainable urban planning and design. The whole neighbourhood we stayed in (Alberta – much like Brighton in its hipsterness) has bioswales and other street level drainage built in. Basically permeable sidewalks (ownership extends to the kerb so householders plant up their strip of sidewalk however they like), roof drainage to ground level, street level swales and other features incorporated into street furniture and traffic calming. Drains are clearly marked to encourage people not to use them for disposing nasties. Much of the sidewalk strip was used to grow veggies and fruit – including a nearby pub that harvested salad crops from the street and boasted of it on its menu.
Here in Brighton, a number of partners including the Council and Environment Agency have launched a pilot ‘sustainable drainage’ scheme in Portslade. Great, but surely we could be bolder?
