The District of Columbia's efforts to get $12 million in federal funds for six development projects failed yesterday as the Department of Housing and Urban Development announced it is holding the city's applications for future consideration.

A spokesman for the city's department of Housing and Community Development said the office has not yet received official notification from HUD and cannot immediately determine what the next steps will be.

Once HUD's reasons for not funding the projects have been analyzed, the spokesman said, a meeting will be arranged among city officials, private investors and HUD.

Washington has applied for a total of $12 million in federal grants for six different projects. These include a 300,000-square-foot shopping center proposed by hardware store executive John W. Hechinger on land owned by his company at H Street, Benning Road and Bladensburg Road NE; a dental clinic at 11th and Massachusetts NW: enlargement of a factory at Third and N NE: improvement and expansion of the partly vacant Stanton Plaza shopping center at Alabama Avenue and Stanton Road SE; expansion of the D.C. Research and Development Corp. facility in the 1100 block of 9th Street NW; and expansion of a home purchase assistance project operated by the D.C. Development Corp.

The city's projects were not considered during HUD's first round of awards in April because the District failed to file in time.

A spokesman for HUD said yesterday that "at least some of the (District's) applications are good" and "worthy of consideration," rather than being rejected outright.

"Whether each and everyone will be carried over has yet to be decided," he said. "By and large, Washington's applications will be carried over." The next awards will be made in October.

The HUD spokesman said federal officials will discuss the applications with the city to see what changes can be made and what further private investment can be found in order for the city's applications to win approval.

Washington is competing with several other cities for $400 million annually in "urban development action grants" authorized by Congress last year. The $12 million the city is seeking would be lent to private sponsors, under the city's proposal, to be matched by an estimated $52 million in additional investment.
