The project will deliver both market rate and workforce housing, according to Mayor Adrian Fenty--as well as pay for improvements to the school. "LCOR is a highly capable developer," he says in a prepared statement. "They know how to make public-private partnerships work." The Mayor's office did not return calls in time for deadline.

LCOR proposed building between 120 and 130 units of housing above the future Tenley library and on the land that lies between the library and Janney Elementary. It will be designed to LEED standards. The next stages of the project include meetings with the local groups to make sure the project is acceptable to the community, according to the mayor's office.

The District has been aggressive in bidding out available land parcels for public-private partnerships. For instance, in May it he issued a Request for Expressions of Interest for a master developer to redevelop the Hill East neighborhood on the Anacostia River--a 50-acre plot of land includes the former DC General Hospital campus. It is also seeking a developer for a 90,000-sf area behind the 88-year-old Lincoln Theatre in the city's up-and-coming U Street Corridor.
