My solution to the future development of this site and smart growth objectives was to develop a unique bicycle community. Ok so this shows my bias toward alternative forms of transportation. Could a bicycle community work?
The sketch shows the railtrail at bottom and the dotted lines are cycling paths that connect to it from the community. Alternatively, cars enter the site from the north (top) with separate access (no more bike / car collisions). Each bicycle street terminates in a park. Each car street terminates in a parking lot.
The blocks along the rail trail are commercial, retail infrastructure for the community and larger context of bicycle riders, all able to access by the rail trail connecting neighboring towns.
