The infrastructure for the second tower is in place and Parkwayhas approvals for a structure of as much as 275,000 sf on as manyas 25 stories atop the existing garage, Robert Zuritsky, Parkway'spresident, tells GlobeSt.com. The current Center City marketconditions prompted him to unearth the plans now and "put outfeelers and see if there's interest," he says.

Parkway has enlisted James Egan, SVP of the local office ofGrubb & Ellis, to create a marketing package for the proposeddevelopment. The package will go out next week, Zuritsky says. Itis unusual in that neither the plan nor the land is directly forsale. Parkway already has a tower design, and Egan has developed aseries of parameters for the building, which includes office, hotelor residential options. The developer is seeking either an officeuser or a development partner.

Because of the potential variables, both Egan and Zuritsky saythe marketing package carries no prices. "We're testing the marketto see which becomes the highest and best use of the location,"Egan tells GlobeSt.com.
