Radio announcements lauding Prince George's County as a "special place to live" with "superprofessional" police and "cooperative, fantastic people" are sounding forth over many AM and FM radio stations this week.

The latest effort in the New Quality campaign to get people and industry interested in Prince George's County, the radio spots record the "spntaneous reactions" of citizens chosen from PTAs, civic associations and town meetings, according to County Executive Winfield M. Kelly Jr., who unveiled the new program in a press conference last week.

The six advertisements, with voices and accents intimating the diverse makeup of the county, extoll the school system, police and fire departments, and the desire on the part of government officials to "move" with the growth of its people. Created and produced by Earle Palmer Brown and Associates, a District advertising firm, the spots are aimed at regional businesses and industry that may be interested in moving to Prince George's.

The county has purchased $34,483 worth of air time for the next six weeks.

"Eighty per cent of new business comes from within a 100-mile radius of the region," said Sonny Long, chairman of the county's Economic Development Committee. "For about three or four years, there was no growth in the county. And that has stuck in the minds of a number of local businesses.

This is to inform them we're growing again."

Within the past two years, the economic development program underscoring Kelly's "New Quality" theme has been promoting Prince George's through television and national magazine advertising. Kelly said the county has received 1,500 responses as a result of the promotion efforts.

Of those responding, 31 companies have moved into the county during the past year, adding 2,300 jobs worth $32 million at local cash registers and producing $650,000 from the businesses in annual property tax revenues.

Kelly said the promotion was also designed to show "existing businesses that the government wants to help them through financial assistance and manpower training."

Kelly's much heralded "New Quality" program for industry is coupled with a strong movement against apartment projects in the county. "We can select the growth we want," he said.

"Of several apartment complexes begun in the region, not one new apartment project has started in the county this year," Kelly said proudly. "We want to increase the housing stock, get better style, move toward down-zoning."

Asked whether the "good quality" development officials seek could become subjective and a matter of taste - theirs - Kelly said that "quality is not that subjective. If something is tastefully done, not overly built and a tax-taker, we'd want it."
