I'm looking to split this polygon into 3 separate polygons.
Normally, this would be a simple task however, I am hitting a wall on how to perform this split without actual boundaries.
Any help or suggestion would be great. Thanks!
You can use Multipart To Singlepart tool from Data Management tools\Features\Multipart To Singlepart
to creates a feature class containing singlepart features generated by separating multipart input features
You can use Explode on the Advanced Editing toolbar to separate a selected multipart feature into its individual, component features. This would be useful if you needed to alter the attributes of one of the elements in a multipart feature.
The parts of the multipart feature become independent features, with each one being assigned identical attribute values.
