12 Reasons to Love the American Grid, and Doug Allen

Paul Knight, a planner with the design firm Historical Concepts, can give you a dozen reasons for just about anything. More importantly, he can give you reasons for brushing up on the lectures of former Georgia Tech professor Douglas Allen. Allen was a giant in the field of urban planning, and fortunately some of his former students and colleagues have carried on his work following his passing. Paul is one of them, helping form the Douglas Allen Institute.

This may all sound very academic, and I know I often take shots at academia. But, when it works well, it’s amazing the impact one really great professor can have on so many people. I wanted to talk with Doug, because I know just how brilliant the man was, and how it’s even better that his work will live on for future generations. For example, the Institute was able to videotape his lectures from his “History of Urban Form” course, and they’ve made them available for free on YouTube. If you’re at all interested in the history of cities and towns, I couldn’t recommend something more highly.

Several years ago, Paul also opened my eyes to the whole rabbit hole of base 12 versus base 10 measurements. I’m now a firm believer in base 12. In this episode, Paul even lets me know there’s a Dozenal Society. I should’ve guessed, but had no idea.

Since we made a few minor errors in the podcast, here are the official corrections:

* In regards to the “Jeffersonian” grid, and what it really should be called, here’s what Allen had in his lecture notes: “Congress formed a committee originally chaired by Thomas Jefferson, but  eventually by Hugh Williamson of North Carolina. Jefferson had proposed ten states and  a measurement system of his own invention based on the nautical mile. After Jefferson was called away to Paris, Williamson’s committee adopted the Gunter Chain and the system of feet and inches that are in use today.”

* I was trying to think of the “4 rod Main Street,” which is a historic pattern throughout much of the United Kingdom and the US. The rod is 16.5 feet, and the four rod street was thus 66 feet wide. 66 feet is also one chain.

* The reason a mile is 5,280 feet is that it’s exactly 320 rods.

* The book I couldn’t remember was “Measuring America: How the United States was Shaped by the Greatest Land Sale in History.”

Please look at the work of the Douglas Allen Institute, and the Urban Form Standard that Paul mentions. It’s really pretty terrific work.
