I have uploaded my site boundary file, why are the boundary lines showing in black?

The imported boundaries will be shown as black boundary lines. You will need to highlight which boundary lines show the main site of the application. This will turn the black boundary to red, showing that the boundary is set. If there are any additional related properties to be included, you can select the ‘Blue line boundary’ tool and continue to mark in the same way. Complete this by clicking ‘Confirm selection’ to continue with your application.
