National Trust Releases New 'Atlas of ReUrbanism'

Laura Bliss reports on a new set of maps from the National Trust for Historic Preservation that offers a "data-driven perspective" to the question of the effect of historic preservation on housing affordability.

"The Atlas of ReUrbanism charts 50 U.S. cities by the 'character' of their building stock," explains Bliss. Yes, the word "character" is charged in urbanist politics, but for the purposes of the Atlas of ReUrbanism, however, the word measures "the median age of buildings, the diversity of age of the buildings, and the size of buildings and parcels…"

The Atlas illustrates the perhaps unsurprising conclusion that "high-character blocks tend to have higher shares and numbers of affordable units of rental housing, compared to low-scoring blocks," writes Bliss, before noting that Kyle Shelton applied the Atlas to Philadelphia's example and nonetheless found some surprising results. Bliss concludes the article by making a few suggestions about how the tool could be improved.
