Parcel split: split using an area description

This topic applies to ArcGIS for Desktop Standard and ArcGIS for Desktop Advanced only.

Complexity: Beginner Data Requirement: Local Government Sample Data Data Path: \TaxParcelEditingMap\MapsandGeodatabase\ Goal: Learn how to split acreage parcels using an area description in the Local Government Information model for ArcGIS.

When the parcel fabric is enabled with the Local Government Information Model, efficient and automated workflows can be used to perform common parcel editing tasks such as a parcel merge and a parcel split. This workflow describes the steps for the Parcel Split: Area Description automated workflow.

The workflow uses the sample dataset that is downloaded with the Tax Parcel Editing map on the ArcGIS Resources website. To use the automated workflows on the sample data, enable the parcel fabric in the sample data with the Local Government Information Model.

Learn how to migrate parcel data to the parcel fabric schema in the Local Government Information Model.

The workflow consists of the components shown in the diagram below:

Legal description

A legal description for a parcel split using area may look like this:

The west half of parcel 1916326003; described as T2N, R10E, SEC 16 PART OF E 1/2 OF SW 1/4 BEG AT PT DIST N 89-02-10 W 517.71 FT FROM CEN OF SEC, TH S 00-57-50 E 230 FT, TH N 89-02-10 W 289.25 FT, TH N 00-57-50 W 230 FT, TH S 89-02-10 E 289.25 FT TO BEG EXC N 60 FT TAKEN FOR HWY 1.13 A C145J

Search for parent parcel

Steps:

1. Open the TaxParcelEditingMap document located in the MapsandGeodatabase folder.
2. In the Table Of Contents window, make only the Tax Parcels layer and the Tax Lines Anno layer selectable.

For this workflow using the sample data, the visibility of the Lots and Units layer and Historic Parcels layer has been turned off.

3. Search for the parent parcel that will be divided. In the sample dataset in the TaxParcelEditingMap document, search for parcel 1916326003.
Tip:

A Prescriptive Right Of Way (encumbrance parcel) and a subdivision boundary overlaps with parcel 1916326003. For visual simplicity, turn off the visibility of the Encumbrances and Subs and Condos layers

Select parent parcel

Steps:

1. Start an edit session and use the Select Parcel Features tool located on the Parcel Editing toolbar to select the parcel you want to divide. In the TaxParcelEditingMap, using the sample dataset, select parcel 19-16-326-003.

Divide parent parcel

Steps:

1. Right-click the leftmost line of the selected parcel and click Parcel Division.

   The Parcel Division command uses the position of the mouse cursor to determine the parcel line to use as the split-line. The parcel line closest to the position of the right-click is used as the split-line. The split-line bearing is the bearing of the line that will be used to divide the parcel.

   

For parcel 19-16-326-003, the leftmost parcel line will be used as the split-line.
2. On the Parcel Division dialog box leave the Plan set to the system default <map> plan.

   When working with your own data, you would click Plan to choose or create the plan that represents the new parcel.

The parcel fabric plan represents the legal document recording a parcel merge, subdivision, and so on. Parcels are created in plans. Plans are managed in the Plan Directory dialog box, which is opened by clicking Plan on the Parcel Details dialog box.

Tip:

When setting the Accuracy category for a plan, all parcels in the plan will inherit that accuracy value.

3. Click Template to open the Select Feature Template dialog box and choose the Tax Parcels feature template for the new split parcels.

4. Choose by proportional area from the Divide this parcel drop-down list.
5. Set the Number of parts to 2.
When dividing a parcel using proportional area, the entire parcel is divided and proportioned into equal areas based on the number of parts you specified.
6. Leave the bearing value for the Split-line bearing.

   The split-line bearing is the bearing of the line that will be used to divide the parcel. It is the same bearing as the parcel line near which you right-clicked.

7. Leave Starting from the set to West.
The parcel will be divided from west to east using the split-line bearing. The Parcel Division command automatically sets the direction of the parcel division to be from west to east because you right-clicked near the leftmost parcel line. If you right-clicked the rightmost parcel line, the direction of the division would be from east to west. The same is true if you clicked the topmost parcel where the direction of the division would be from north to south.

8. Do not choose Activate parcel namer tool when I click OK and click OK to divide the parcel.
The parcels are divided proportionally and the original parent parcel is saved as historic.

Annotate parcels

Steps:

1. If necessary, close or dock the Parcel Details dialog box.
2. Make sure the Tax Lines Anno layer is turned on in the Table Of Contents window.

In the TaxParcelEditingMap document, new annotation is not automatically created when new parcels are added.

Learn more about annotation in the TaxParcelEditingMap document

Annotation is created using the Annotate Parcel Courses tool , which handles the duplication of annotation on parcel lines.

3. With the new parcels selected, click the Annotate Parcel Courses tool on the Parcel Editor toolbar.
4. Select ParcelDimensions - 1:1200 on the Annotate Selected Features dialog box and click OK.

   Click Yes to re-create annotation.

5. If necessary, use theEdit Annotation tool to edit and change the placement of the generated annotation.

Attribute parcels

The final step in the workflow is to update the attributes of the new parcels:

Steps:

1. Use the selection chip to select the new, divided parcels and open the Attributes window.
2. Select a parcel from the parcel list under Tax Parcels and update attributes such as the Parcel Identification Number, StatedArea, LegalStartDate, and Accuracy.

   The LegalStartDate attribute should correspond to the date on the parcel's plan. If the Accuracy attribute is left empty, the value is inherited internally from the plan accuracy. You can override the plan accuracy by specifying a different parcel accuracy. Accuracy values are used in the parcel fabric least-squares adjustment.

3. Update the attributes of the remaining parcels in the list.
Tip:

You can also updated the attributes of a single, selected parcel under the Properties tab of the Parcel Details dialog box.

4. Optionally update the attributes of the historic parcels:
   1. Turn on the Historic Parcels layer in the Table Of Contents window.
   2. Use the selection chip to select the historic parcel in the map.
   3. Open the Parcel Details dialog box and update attributes such as LegalStartDate, LegalEndDate, and Reason Parcel Retired.
