The Philadelphia City Council has enacted Bill No. 250523, amending Title 14 of The Philadelphia Code, "Zoning and Planning." This ordinance introduces significant revisions, clarifications, and technical changes across various sections of the code. Key amendments include the definition of "Flag Lot," removal of "Pool or Billiards Room" as a defined use, and updated review authority for the City Planning Commission concerning Mixed Income Housing and Residential Housing Projects in overlay districts. The bill also modifies prohibited uses on Germantown Avenue, refines the "Personal Vehicle Repair and Maintenance" use category, and updates use tables for residential and special purpose zoning districts. Further changes involve adjustments to green roof eligibility criteria, revisions to steep slope protection, and new requirements for landscape and tree preservation plans, particularly concerning heritage tree removal and replacement guidelines (e.g., exempting invasive species). Parking and loading standards are also extensively updated, covering applicability for changes of use, new/modified parking lots, and specific landscape and screening requirements, including buffer fencing materials and interior landscaping ratios. Additionally, the ordinance revises required off-street loading spaces for industrial districts, particularly for Research and Development uses. The bill also amends the composition and notification procedures of the Historical Commission and repeals demolition moratoriums for the West Christian Street Area and Victorian Roxborough Area, while renumbering the Wissahickon Historic District moratorium.
