The site selected by GSA on January 3, 1963, for the new FBI headquarters were two city blocks bounded by Pennsylvania Avenue NW, 9th Street NW, E Street NW, and 10th Street NW. GSA administrator Bernard Boutin said the site was selected after informal consultation with the President's Council on Pennsylvania Avenue and the National Capital Planning Commission (NCPC; which had statutory power to approve any major construction in the D.C. metropolitan area). Boutin said construction of the new FBI building would help revitalize the Pennsylvania Avenue area as suggested by both the Ad Hoc Committee on Federal Office Space and the President's Council on Pennsylvania Avenue. Boutin emphasized that the design of the new structure would be in harmony with other buildings planned by the President's Council on Pennsylvania Avenue, and would necessitate the closing of a short section of D Street NW between 9th and 10th Streets NW. More than 100 small retail businesses were to be evicted.
