Hello,

I have two polygon layers (shown in the attached image). I want to be able to select the smaller polygons from the cyan-colored parcels that are at least 80% covered by the larger reddish polygon layer. Then of course I would create a new layer from the selection.

How would I make a selection based on 80% or greater overlap from another polygon layer?

select by location for those that intersect,  remove the select by location for those that are completely within, will give you those that are partially within.  Intersect those, retaining area information will allow you to calculate and sift the remainder.

Then there is Tabulate intersection... I only mention it should you have an Advanced license.
