it would not block the Northwest One plan. Demolition of the participating structures occurred in 2008, with residents dispersed to other public housing projects in the city. In 2009, the redeveloped Walker-Jones Education Campus and the Northwest One Neighborhood Library opened. But then redevelopment stopped. DCHA never assigned anyone to oversee the project, which left no one to push the developers to fulfill their agreement. DCHA itself was required to move from its headquarters at 1133 North Capitol Street NE to vacate and demolish its own headquarters to make way for the planned new housing, but the agency never did so. DCHA then lost the blueprints for the project, and only relocated them in June 2013. DCHA then discovered—after it had demolished the building—that the Temple Court Apartments were built with a mortgage insured by the United States Department of Housing and Urban Development. This $3.9 million insurance policy required that only subsidized housing could be built on the Temple Court land, but the Northwest One project envisioned market-rate, office, and retail use there. Mayor Adrian Fenty and Mayor Vincent C. Gray both pledged to resolve the issue, but never did. Only two of the many planned Northwest One buildings were constructed. One was the 2M Street Apartments at 2 M Street NE. Built with $16.8 million in DCHA funds, only 93 of its 314 units are subsidized for low-income residents. The other was the Severna Apartments, owned and built by Bible Way Temple. The $15.7 million building (constructed with $1.9 million in DCHA funds) opened in 2011. All of its units are for low-income residents. The construction of the nearby NoMa - Gallaudet University Metro station and a surge in property values sparked redevelopment of the area. New Sursum Corda project In August 2015, Sursum Corda Cooperative Association announced it had partnered with Winn Development Co. and adjacent private landowners in the neighborhood to redevelop the Sursum Corda co-op and the surrounding of land into a new high-density, mixed use housing development. The development, which will occur in two phases, will contain more than 1,100 apartments, six times the co-op's current capacity. Five buildings, with of residential space, of retail space, and 800 parking spaces, will be constructed on two parcels. The first phase, constructed on the parcel at L and 1st Streets NE, will contain three buildings of 164 units, 166 units, and 100 units. The second phase,
