Now that principles for development have been established (see attached PDF), a team of designers worked through a marathon design workshop March 1-3 in conjunction with leaders from the City Planning Commission and civic leaders to develop the first concepts for the 7 miles project area.  These first drawings and sketches will lay the groundwork for the 6 month design phase of the project.  The team of local, national and international designers convened in Philadelphia to develop this preliminary vision in charette style, which is a messy but productive way to combine architects and planners' visions into a cohesive whole.  As with any session related to this process, the workshop was open to the public and well attended as 500 citizens turned out.
