The Philadelphia City Council authorized the revision of lines and grades on City Plan No. 230, specifically vacating the legally open portion of Cresson Street between Ridge Avenue and Osborn Street. This authorization is conditional upon the property owners or party in interest filing agreements to release the City from damages and indemnifying the City, and covering the cost of advertising a public hearing. Additionally, the ordinance will only become effective upon payment of $200 into the City Treasury within 120 days of becoming law, effectively removing a segment of Cresson Street from public use.
