The flexible urban grid: adaptation, expansion and evolution in Philadelphia's city block morphology
, 2023 This study examines the evolution of Philadelphia’s city block morphology between 1683, when the city was planned by William Penn, and 1900, when urban expansion abandoned the grid. The study uses both quantitative and qualitative assessment.
