I don't know what that number is. There were 5 pages.
To see the document go to this page:
https://aca.slcgov.com/Citizen/Cap/C...bName=PLANNING
Scroll down and click search and you should see Tower 8 in the results (if not there search for petition no. PLNPCM2018-00868). Click on the link to the petition. Then on the petition page click the dropdown menu where it says Record Info and select attachments. Everything they've uploaded will show up there. May be more later.
