More formal arrangements are possible in the <br /> medium and high density residential districts as well as the commercial <br /> industrial .-,nd econer is deveicp..i lent zoning designations. <br /> 97 Staff is suggesting this addition since more formal landscaping arrangements would seem to be appropriate in the <br /> economic development zoning districts as well. <br /> Orange County, North Carolina—Unified Development Ordinance Page 6-48 <br />
