Prince George's County planning officials said yesterday that the county will experience a boom in white-collar service industries by the turn of the century that should bring in more than 24,000 jobs.

"We've recognized a trend in the evolution of industrial development from heavy industry to what we could call cleaner industry," project planner John N. Funk III told the County Council yesterday.

That growth, he said, will be centered almost entirely in business park-type complexes located in the area immediately surrounding the Capital Beltway. Industrially zoned land constitutes 14,000 acres, or 5 percent of the county's 318,000 total acres. Of that, 8,500 acres are vacant, Funk said.

Total employment for that industrial space is expected to grow between 1980 and the year 2000, planners found, from 47,400 to 71,900 jobs.

Because the high technology and consumer service companies that have been attracted to Prince George's use less land space, planners say that sector will continue to be the fastest-growing segment of the county's economy.

Council members questioned whether the county's infrastructure -- water, sewer and other services -- will be able to handle the projected increases.

John W. Sloan, a planner who worked on the report, said that a separate report on that issue will be released by the Maryland-National Park and Planning Commission.
