State of North Carolina – 2001

For the North Carolina Department of Transportation, GBB conducted a visible litter survey of 111 primary sites, plus four landfill access route sites. The survey found that North Carolina had a lower litter rate than the national average. The litter rate along the urban limited access roads (freeways) was approximately half the national average. The litter rate along urban streets is also below the national average except for all but the commercial streets. However, litter along rural freeways and other rural state highways was found to be higher than the average of other states surveyed. The 2001 study found that Adopt-a-Highway and Keep America Beautiful programs have reduced litter; however, litter rates are higher along rural local roads (state secondary roads) than for other states with comparable programs. Two thirds of all the litter encountered by motorists and pedestrians was estimated to be along rural freeways and other rural state highways. The Litter Survey is being used by the State of North Carolina to plan effective litter management programs in areas where litter management is most needed.
