North Carolina transportation officials are using federal stimulus money to make changes in the way water runoff at the Interstate 77 Welcome Center in Charlotte is treated.
The N.C. Department of Transportation says it will spend $62,000 to build a wetland area, so water running from the rest area can be treated before it enters a nearby tributary of Sugar Creek.
Currently, water runoff from the welcome center includes oils, metals and other sediment from vehicles parked in the lot. State officials say the new wetland will treat polluted water, then allow it to flow into the creek. Pedulla Trucking, Excavating and Grading Company of Mooresville will handle the work, which began in mid-December and is scheduled for completion by March.
