Connections through Walkability

Along the same lines as Blaise, I research a couple of organizations dealing with walk-ability.

www.walkscore.com
This website promotes and advertises just how walk-able a city is due to various inputs, coffee shops, transit, etc.

I also found myself increasingly interested in connectivity and how Philadelphia creates a large opportunity to connect numerous resources. How can the both waterfronts in Philadelphia, although very different be connected to each other and be openly accessible?

A similar effort is being persuade in the Spring Garden GreenWay. This proposal connects both waterfronts, provides a "green way", new bike paths, walkways, and new traffic patterns. This proposal is a larger unification between numerous cities in a hope of expanding the Green Way along the East Coast.

The Spring Garden Greenway I think is missing a large opportunity and connecting existing programs within the city, such as Farm to City, www.farmtocity.org, connecting business districts to residential areas, incorporating existing transit, and connecting Philadelphia's numerous University communities.

I think an important purpose of walkability within a city is destination and how we can bring resources within these created pathways.
