Sw Headwall (OpenData)

SwHeadwall represents a structure at a pipe end on the Stormwater network, installed to reinforce a slope steeper than 50 degrees, and provide erosion protection. The Stormwater network drains surface water from the land and roading system, and transports it into the waterway network or ocean. It is spatially abstracted to a point, and is a node on the Stormwater network. IDS-compliant SwHeadwall data will be inserted via the SwHeadwallStage table. When deleted or edited, the record is Archived. A snapshot of the feature record, before it is edited, will be sent to the archive table immediately prior to the first edit of the day for that record. SwHeadwall assets are represented in SAP as equipment objects.
