In the "D", "D" doesn't really stand for "Detroit", but "Demolition." Take a look around and you'll notice a great number of buildings marked on the front with a circled "D" in faint chalk.

The Heidelberg Project is an outdoor art project in Detroit, Michigan. It was created in 1986 by artist Tyree Guyton and his grandfather Sam Mackey ("Grandpa Sam") as an outdoor art environment in the McDougall-Hunt neighborhood on the city's east side, just north of the city's historically African-American Black Bottom area.
