Massport has started looking for companies willing to sign a long-term lease to develop up to 2 1/2 acres of land along Congress Street.
About 1.1 acres of the land is ready for development now - it's currently used as a parking lot. The rest would require building over an existing Silver Line right of way.
Massport says the land would support up to 600,000 square feet of "transit-oriented, mixed-use development," which wouldn't need as much parking on site as normally required by the city because of the proximity of Massport's new mega-garage.
Bonus: "Nearby open space and roadways ensure permanent city and water views."
Detailed bid documents (you need to ask for access, though).
