DC Selects Land Trust Team to Redevelop Langston-Slater Campus Rendering of "Lebanon Village". Click to enlarge. The city-owned site that was the subject of DC's first EquityRFP may be redeveloped using an equity-focused model. On Tuesday, Mayor Bowser's office and the Office of the Deputy Mayor for Planning and Economic Development (DMPED) selected a co-development team for the Langston-Slater school campus in Truxton Circle: a team that includes the Douglass Community Land Trust (Douglass CLT). The plan put forth by the Douglass CLT team would deliver 55 mixed-income units, including some for-sale units and units with permanent affordability, to the site of the Slater and John Mercer Langston Elementary School buildings at 33-45 P Street NW (map). More specifically, there will be 43 rental apartments and 12 infill townhouses, along with 21 surface parking spaces. Roughly 49% of the units in the "Lebanon Village" development will be affordable to households earning up to 30%, 50%, and 80% of area median income.
