Hello All, (ArcGIS Pro 10.7.2)
I am trying to automate a process that is a fairly simple, but always a last minute request.
The Request is for the Zoning department that has to send notifications to property owners of properties within 300ft of a parcel requesting a zoning amendment (so they in theory have time for input on the amendment). They want a table with the resulting parcels, and all of the mailing address fields concatenated. These fields are currently:

Steps Taken Which I have built in Model Builder
-Select by attributes
-Select by location (add to current selection)
-Summarize Data (exporting selected fields to table)

This provides me with a table of only the fields they want, but the mailing address fields are not concatenated.
This process gets repeated for several parcels. I am hoping to simplify this so it that someone who doesn't use Pro or really know how to use excel, can input 1 parcel # and receive the formatted spreadsheet as they need. (Also, was thinking of building this process in WebApp Builder but couldn't see a streamlined way - any ideas on that would be even better! Then they don't even need to open Pro)
Thank you for your kind assistance!
