The project is specifically located east of US Hwy 17, between the Southern Comfort apartment complex and Kids Comer Learning Center. The purpose of the site visit was to determine if the subject property contained jurisdictional areas (i.e. wetlands, Waters of the US) regulated by the US Army Corps of Engineers (COE) or the NC Division of Environmental Health and Natural Resources (DEHNR). Upon review of the subject property, it was determined that the entire property consists of uplands. The subject property does not contain any jurisdictional wetlands and/or Waters of the US.
