This post on Original Green begins by contrasting Atlanta, Georgia, with Florence, Italy. The intial point it’s making is that Florence’s many little streets are superior to Altanta’s massive highways. My personal experience supports that argument; Florence is one of the most pleasant, charming cities I’ve ever visited in large part due to its infrastructure.
But the article also goes on to point out that smaller scale development with a lot of little streets are more efficient. Contrasting Seaside, Florida, with Miami, it reveals that many little streets allow for more land to be developed with less being paved over as roads. The post looks at value from several different angles and is well worth a read.
