Green Roofs Rising
Healthy cities are green cities. Increasingly, that means green roofs. There is a movement underway where cities are incentivizing and even mandating that building owners and property developers devote a portion of the rooftop to green space. What began in Germany is becoming common in North America. Toronto was the first city in North America with a green roof mandate. Now, green roofs have spread to San Francisco, Chicago, Washington D.C., Denver, and most recently Portland, Oregon.
