An economic analysis of sediment control use at construction sites in Greenville County, South Carolina.

摘要

Soil erosion from construction sites can cause sedimentation of nearby water bodies. Mandatory sediment controls can reduce sedimentation. What determines the degree to which sediment controls meet regulatory standards for installation and maintenance? A conditional-multinomial logit model is estimated with data from 85 construction sites that were audited in 2001 or 2005 in Greenville County, SC to determine whether 147 sediment ponds or traps were installed correctly, properly maintained, or both. Costs of maintenance positively affect the probability that a sediment pond or trap is properly maintained. Engineering experience positively affects the probability that a structure is properly maintained. Construction site distance from the county's regulatory office positively affects the probability that a sediment control is installed incorrectly.
