Oh obligated and $94, 100, 000 or 79 per cent had been accomplished. As the new facilities on South Mesa or at outlying sites were occupied, the vacated structures were converted to other use or were considered for demolition or disposal. Community Construction A five-year $65, 500, 000 program to completely modernize and to expand Los Alamos’ community was announced on March 12, 1948, The community plant then visualized has been completed, except for replacement of temporary-type housing which was scheduled to begin in fiscal year 1951 but was delayed until fiscal year 1954 because of the Korean emer- gency. Community Population Los Alamos had 7, 500 residents in mid-1947; 10, 620 in mid-1950; and 12, 700 in mid-1953. (Details of community operations are recorded in Chapter IV of this report.) White Rock Construction Camp In order to bring more contractors into the Los Alamos construction picture, a tempo- rary (five year) camp was built at White Rock, eight’miles south of Los Alamos, prior to December 1949, Cost was $4,500,000. Occupancy was near maximum, 2,352, in July 1950. As the peak of Los Alamos construction passed, use of White Rock declined. Occupancy for calendar year 1952 was less than 50 per cent and as of June 30, 1953, less than 20 per cent. In the light of this situation, 250 of the 413 dwelling units and 6 dormitories were declared surplus in May 1953 to the General Services Administration. Remaining houses were to be used until no longer required for construction workers, Present plans anticipate transfer of some used White Rock buildings to NPG, Contracts for Los Alamos Operations University of California -- For operation of the Los Alamos Scientific Laboratory.
