Now the Republic of Society Hill wants to opt out again. Over the last three weeks, Squilla has introduced two bills that would tweak the city zoning code to make it harder to build affordable apartments in Society Hill. The bills also would increase parking requirements for new construction in the neighborhood and severely limit the height of buildings on Walnut Street. A separate measure would exempt Society Hill — the city’s most historic neighborhood — from having to comply with the Kenney administration’s new incentives to encourage developers to choose preservation over demolition. (Ironically, it was Squilla who introduced the bill creating those incentives.)
