Clipping polygons results in some empty outputs

Hey ArcGIS community!

I'm trying to clip a polygon layer. However, the output shows some empty polygons in the clip area. See attached pictures. Not sure why this is happening. I've tried clipping with ArcMap as well as ArcGIS Pro. I've also tried pairwise clipping as ArcGIS Pro suggested. But they all give outputs with empty polygons.

Thank you so much!

how are you assessing "empty"? visually? or by clicking on an apparently empty area and finding no record in the table selected? Just trying to rule out a symbology issue

Hi Dan!

Thank you so much for the reply. Visually empty as well as no record in the table. Tried "Repair Geometry" but that didn't seem to work either...

Thanks again!

I would try, MultipartToSinglepart tool to produce a new file in case there are multipart shapes (which can be problematic), then follow that up with a Check Geometry. Examine that last result to see what geometry you have left over for clipping (which be the final step if the last one worked)
