You might need to change the area boundaries if you need to subdivide an area, or if you want to delete a network object that is currently an area boundary.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ The application displays a warning if you remove a regulator that is an area boundary.

# Change the area boundaries

1. In the Areas module, select the area that you want to edit.
2. In the **Areas > Boundaries** tab, click **Edit** to make the boundaries editable.
3. Select the old boundary that you want to remove and click **Remove** to delete the old boundary.
4. Click **Add** to open the Add Boundaries screen.
5. Select the **Regulator** that you want to add as a boundary for the area.
6. Specify the boundary direction:
  - *Up* - the regulator is at the upstream border of the area
  - *Down* - the regulator is at the downstream border of the area
7. Select the **Top Regulator** checkbox if the regulator should be set as a top regulator. See <u>[What is a Top Regulator?](https://rubiconwater.atlassian.net/wiki/spaces/SMNC/pages/2001011526)</u>
8. (Optional) Set the **Sequence Number**. This is used to order the results in some reports (for example, the [Meter Reading report](https://rubiconwater.atlassian.net/wiki/spaces/RptNC/pages/1986953846)).
9. Click **Save** to save your changes.

# Generate and View the Area

1. Click the **View in Network** button.
  - The application generates the area to determine what network objects belong within the area.
  - The Network Viewer opens to display the area.
2. Check the area to confirm that the boundaries are correct and that all the appropriate objects are included.
