Forgotten Space Above Us: Living Roofs

The concept of a living roof dates back millennia. Humans excavated shelter underground, in hillsides, or on the sides of steep cliffs, which were intentionally covered with living vegetation (despite the structural flaws a meandering root might pose). These dwellings were naturally cooler, provided aesthetic benefits and limited the erosive forces exerted on structures. As the dwellings evolved above ground, living roofs maintained their place in areas across the world, from the the desert southwest to Scandinavia. In our quest to remove man from nature; to modernize and create entirely new environments, we lost sense of how to integrate the natural world with the artificial. Our modern era of intensive urban habitation has given way to concrete, asphalt and steel, leaving behind acres of gray, heat-absorbing rooftops.

However, the myriad of benefits provided by a living roof has been "rediscovered" by urban designers, architects and builders alike. In the quest to reduce our overall impact on the world around us (from reduced heating costs in winter to small-scale air purification plants can provide), living roofs are being reintroduced into the mainstream. The website Ecosalon.com has highlighted 17 examples from across the world, broadening the envelope of what is possible on the underutilized space above us. In our small 7 by 7 city, we here at SFB believe San Francisco should not be left out of this wonderful trend.

SFB and the Geary Corridor

Congratulations to SFB associate Jonathan Goldberg for appointment to the Geary Corridor Bus Rapid Transit Citizens Advisory Committee (or simply GCAC). Jonathan was selected among a list of qualified candidates and appointed to represent the Downtown neighborhood during the environmental analysis of the Geary BRT project. With 10 other members representing interests along the Geary Boulevard Corridor, Jonathan will be providing input to refine the BRT alternatives and ultimately select a preferred alternative for the project.

We are hopeful and excited that Jonathan will bring a contemplative and open-minded approach to the CAC, as well as a keen eye for streetscape design, beautification and transit efficacy. Congrats Jonathan!
