"The Dreaded Density Issue
Having worked in communities big and small across the continent, we’ve had ample opportunity to test ideas and find approaches that work best. Urban design details. Outreach tactics. Implementation tricks. Many of these lessons are transferable, which is why we’ve created “Back of the Envelope,” a weekly feature where we jot ‘em down for your consideration.
A number of recent conversations with Stefanos Polyzoides, Howard Blackson, and Matt Lambert regarding density and residential types has me thinking about building typology as one solution to visualizing and embracing density.
The Lincoln Institute has done a good job of making the touchy subject more approachable on their website and the wonderful aerial photography of Alex S. MacLean goes a long way to clarifying the difference between similar densities that ultimately prove more or less desirable in their final built form. For example, compare the similar densities from San Francisco and Boston below. The narrow buildings around Louisburg Square are human scaled and very approachable from the view of the pedestrian. In contrast, the monolithic buildings in San Francisco create a canyon at the street level and contribute very little to the effort to promote sustainable densities.
Instead of debating the number of units per acres, planners and city staff should consider addressing types of buildings that are permitted within different zoning categories. Not only is this the most understandable approach for the lay person, it’s the most predictable for the builder and the city."
