CALIFORNIA IN BRIEF : YOSEMITE NATIONAL PARK : New Maintenance Buildings Planned

In a first step to reduce human impact on Yosemite Valley, the National Park Service is planning to tear down a score of maintenance buildings and construct new ones in El Portal at the park’s western edge. National Park Service Director James Ridenour said $16 million to make the move is budgeted for 1992. Under a master plan developed for the park, most motor vehicle traffic would eventually be barred from the valley. Shuttle buses would carry more than 3 million visitors a year to and from the 7-mile-long, 1-mile-wide area.
