Roger Lewis’s Rx for greening a city
September 29, 2008

I've long been a fan of University of Maryland architecture professor Roger Lewis, especially for his "Shaping the City" columns in The Washington Post. Roger was articulating the principles of smart growth and livable urbanism long before the rest of us, and his column has in many ways been a model for this blog.
In his newest entry, "Thinking of Bolder Shades of Green," Roger poses the question whether we can go beyond green building techniques and greener personal choices such as using CFL light bulbs and "make an entire city green." He lays out seven sensible principles for doing so:
- Employ smart growth so that future land development and density are linked to transit and other transportation infrastructure
- Create and maintain a fine-grain street pattern for walkability and managed congestion

- Invest in state-of-the-art bus and rail transit
- Use street trees and plantings to provide shade, reduce heat, and filter runoff
- Expand and preserve a city-wide network of connected parks and other open space
- Use open drainage swales and ground absorption to absorb Stormwater rather than relying exclusively on underground piping
- Employ renewable energy technology to generate electricity on a metropolitan scale
Well done, Roger: what a great framework that would make for guiding future investments in city infrastructure.
These ideas and more were discussed at a forum on "greening the world's capital cities" (although their
applicability certainly isn't limited to capitals) held last week in Washington. Roger served as a panel moderator, and conference participants included NRDC's Frances Beinecke as well as numerous NRDC collaborators and friends such as Harriet Tregoning (now head of planning for DC), Dick Moe (National Trust for Historic Preservation), Tom Hicks (US Green Building Council), and Congressman Earl Blumenauer (D-OR), among others.

Thanks for pointing out these great articles, Kaid. I am not sure how I missed these in the Post! It is going to be very interesting to see how designers start moving beyond the green bulding rating systems.

My pleasure, Chris. Unfortunately, it is easy to miss Roger's columns, which are buried in the Saturday Real Estate sections once or twice a month.
There's usually a mention in the upper right hand corner of the RE section when "Shaping the City" appears. They should be on the front page of the Metro section, which for unfathomable reasons prefers to highlight architectural reviews of buildings in New York and the like.
