As part of the National Pollutant Discharge Elimination System (NPDES) Phase II permit, the Town of Apex Environmental Programs Division conducted an inventory of all municipal separate storm sewer system (MS4) components including all public and private stormwater inlets and pipes (12-inch or greater) within Town corporate limits. Town staff used GPS technology to locate and map all stormwater drainage features associated with the MS4.
