At noon Saturday, the most fully developed concept concerned the nexus of J Street Park with its residential border. Currently, J Street dead-ends at the park's parking lot, and other neighborhood streets dead-end at the park perimeter. The team proposes a new street at the park's western edge, with a dozen new single-family lots fronting the street and facing the park. That street would enable development of yet more residential lots along a greenway linking the park with a nearby Episcopal church.
