Migrating road centerlines as unclosed parcels

An unclosed parcel does not rely on an internal traverse loop that closes onto its starting point. In the parcel fabric, unclosed parcels are line features, but are stored as parcels. Unclosed parcels are most commonly used to model street centerlines.

Line features that represent road centerlines are migrated separately from regular parcel data. These line features need to be in their own separate feature class. An empty polygon feature class is added with the line feature class to the topology that is migrated to the fabric.

Steps:

1. Create an empty polygon feature class in the same feature dataset as the line feature class containing the road centerlines.
2. Create a new topology and add both the line feature class and empty polygon feature class to the topology. Add the required set of rules to the topology.
3. Validate the topology and fix any topology errors.
Since there are no polygons, mark the lines Must Be Covered By Boundary Of polygons rule as an exception.
4. Add any system fields to your line feature class that you want to populate and migrate to corresponding fabric system fields.
Fabric system fields added to a line feature class (being migrated as centerlines) are migrated to the parcels table in the parcel fabric. For example, to migrate a centerline road, centerline name, or ID, create and populate a ParcelName field on the line feature class. System fields that are typically added to a polygon feature class are added to the line feature class when it is migrated as stand-alone centerlines.
Note:

Road centerline features are migrated as separate, individual, unclosed parcels based on a ParcelName and PlanName attribute on the feature class. If there is no ParcelName or PlanName attribute, connected line features are migrated as one single, unclosed parcel.

5. If you want to migrate additional, nonsystem fields for your road centerlines, create the same fields in the fabric parcels table.
Any fields on a line feature class (being migrated as centerlines) are migrated to the fabric parcels table.
6. To begin the migration process, open the Load A Topology To A Parcel Fabric geoprocessing tool located under Toolboxes > System Toolboxes > Parcel Fabric Tools.tbx > Data Migration on the Catalog window.
If you want to load a selection of lines, select the lines you want to migrate using the Select Parcel Features tool. If there is a selection present, the topology loader will only load the selected data. If there is no selection present in the map, the entire dataset is loaded.
7. Choose or specify the parcel fabric to which the data will be migrated under Target Parcel Fabric. Choose the road centerline feature class for Input (Topology) Feature Class. Enter any other necessary parameters for your migration and run the tool.

Once loading is complete, the migrated road centerlines are displayed in ArcMap.
