The Holocaust Memorial Museum received its final necessary approval yesterday when the National Capital Planning Commission endorsed the project by an 8-to-2 vote.

Construction of the building on Raoul Wallenberg Place SW (formerly 15th Street) near the Tidal Basin will begin by late fall or early winter, according to museum director Arthur Rosenblatt.

The commission attached a number of conditions to its approval -- concerning landscape design, transportation access and parking, illumination at night and technical details of the excavation process. "We're extremely pleased," Rosenblatt said. "The questions raised can easily be satisfied."

Commission Vice Chairman Robert J. Nash, who voted against the project, said he did so because of "negative environmental impacts." Commission member W. Don MacGillivray sided with Nash, he said, because the project "is devoid of planning for people, for ample transportation and especially for parking."

The Memorial Museum will be built to a revised design approved last month by the Commission of Fine Arts. This design, by architect James I. Freed of I.M. Pei and Partners of New York, calls for a limestone-sheathed, octagonal Hall of Remembrance facing Wallenberg Place, a sky-lit great hall stretching between Wallenberg Place and 14th Street and faced, on the north, with four stark brick towers, and a semicircular entrance plaza on 14th Street.

The 224,000-square-foot building will house large areas for permanent and temporary exhibitions, a library, two auditoriums seating 500 and 200 visitors, respectively, and administrative offices -- but no parking. Plans for two levels of underground parking were dropped, Rosenblatt said, when officials of the Bureau of Engraving and Printing, located directly to the south of the museum site, objected for reasons of security.

MacGillivray, a recent presidential appointee to the NCPC, said the commission needs to spearhead an "in-depth" planning effort for transportation and parking in the Mall area before more projects are approved. Rosenblatt said the Holocaust Memorial Council is working with city and federal officials to come up with a proposal for automobile, bus and pedestrian access to the memorial museum.

Werner Hasenberg, who identified himself as a Jewish survivor of the Nazi concentration camps of Westerbork and Bergen-Belsen, testified against the Memorial Museum because it "is inconsistent with the general purpose of the museums now on the Mall ... is not relevant to the American national experience ... {and} would rob the Holocaust of its Jewish significance by commemorating other victims of Nazism as well." He also objected to "the suggestion that portions of the museum would be named after generous donors."

Rosenblatt said that the issue of crediting donors by name "is being addressed right now," but that it already has been decided there will be "no donors' names in the great symbolic spaces" of the building.

The U.S. Holocaust Memorial Council was established in 1980 by Congress, which also donated the federal land for the building. The council is undertaking to raise $100 million in private funds for construction, exhibitions, programs and endowment.
