# Combining parcels that are adjacent and add up to more than 10 acres

I am using ArcMap 10.7.

My task is to find a site to be developed for parking. Sites are supposed to be greater than 10 acres. But we can also look at adjacent sites that add up to 10 acres. I read something similar in this link:

Merging adjacent polygons to one which sum of attribute values of adjacent ones is between 1000 and 2000?

However, I have not been sure how to apply it. I have tried another rudimentary way which is to select parcels between 0 and 1 acre, then select parcels next to them, then select from them those which are 9+ acres. Then repeat the process from 1 to 2 acres, 2 to 3 acres, etc. However this is time consuming and this leaves a little room for error if say I get a parcel of .05 acres next to one that is 9 acres and they don't add up to more than 10.

I would love to just be able to do this all from the parcels layer. But if there's a way to create the "0 to 1 acre" layer and then select from the parcels layer something like "0 to acre parcels" acres + "parcels" acres >= 10"
