Endwalls differ from ends of pipe in that they have a structure associated with them that controls erosion around the discharge point. The original municipal separated storm sewer system (MS4) inventory (1997-2007); upon which this dataset has its foundation, was funded by the City of Jacksonville and the Florida Department of Transportation District II.
