Advisory Neighborhood Commission 3A will meet tonight to consider a proposal to allow a parking garage, offices, shops, apartments, town houses and a planned union headquarters on the site of the old Corcoran Elementary School at 28th and M streets NW.

Community activists have expressed concern that the project might be out of character with the old, two-story buildings in the neighborhood near the intersection of Wisconsin and Pennsylvania avenues.

The Hotel and Restaurant Employees International Union, based in Ohio, which agreed to buy the tract from the city for $1.8 million at auction last year, has said it wants to convert the school for use as its headquarters, according to ANC 3A Executive Assistant Elizabeth French.

In 1953, the school building was converted to offices for the bridge and tree divisions of the city's Department of Transportation, which were housed there until last year, using the school's former playground as a storage yard.

ANC 3A commissioners will consider a request for a number of variances that would permit development of the property. The developer on the project would be DRG Ventures, a local real-estate development company. DRG Ventures has agreed to buy the property from the hotel and restaurant workers union, and the company would then lease office space to the union, said Joel Brown, an official with DRG Ventures.

The meeting to consider the proposal will be held at 8 o'clock tonight at St. John's Parish Hall, 3240 O St. NW.
