Merge polygons based on a boundary??

I just received some impervious data that I have merged with my building footprints to create 1 layer. However I would like those separate boundaries gone within each parcel. I can't quite figure out how to do that without just creating 1 row in my table.

This is necessary so I can start to calculate the impervious surface % in each parcel and not have inaccurate data due to some of the building footprints and say sidewalks overlapping.

I'd look at the Intersect tool.

https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/intersect.htm

Intersect the parcel layer and the impervious surface layer. Then you can dissolve the features in the intersected layer on parcel ID to get area of impervious surface per parcel ID. Join the resulting tabular data to your parcels. Then you can compare the total parcel area with the impervious area on a per-parcel basis.
