From the Associated Press:
A proliferation of campers and trailers resulting from a drilling boom has prompted Moundsville to impose limits on these sites.
An ordinance recently approved by City Council requires camper and trailer sites to be at least 1 acre. The ordinance also requires the sites to obtain a license from the city for a $10 fee.
The sites provide housing for oil and gas workers.
Mayor Gene Saunders tells WTOV-TV that the ordinance will enable the city to police the sites to ensure they're following regulations and health standards.
