Hi Steve,

You can delete a boundary by double clicking on the middle of the boundary. This will pop up a small box with a delete link inside of it. It is a litlte trickier to work with the maps on an iPad, but I have actually tried it. You will need to double tap (click) fairly quickly in order to get the delete box to load. From there you can tap the delete link and start over. If may be helpful to view the help video on adding a property if you have not already seen it. It is located at http://mylandplan.org/video/how-add-property and walks through the process of deleting as well. Just remember that the mouse clicks are taps and that click and drag would be tap and drag.
