The Philadelphia Regional Port Authority scheduled public briefings next week to talk about how developing about 200 vacant acres known as Southport, at the eastern end of the Navy Yard in South Philadelphia, will affect the port and present economic development opportunities.

The meetings will be at 6 p.m. on Dec. 8 and Dec. 9 at the Philadelphia Sheet Metal Workers Hall, at 1301 S. Columbus Blvd.

The state agency has received seven responses, called "request for qualifications," from firms interested in developing all or part of the maritime property, south of the Walt Whitman Bridge on the Delaware River.

The PRPA board on Dec. 15 will select a "short list" of the proposals and ask for financial and development plans by next June. Those interested in attending the meetings are asked to RSVP Denise Brumbaugh at 215-426-2600 or email her at dbrumbaugh@philaport.com.
