ty! and i forgot to welcome you to the forum!
okay that should have been clear to the appeals reviewer that it is not SFPRP from the parking areas. i have seen cases where niantic has overturned an incorrect appeal decision after posting here, but not many.
in case they don’t reverse the appeal rejection, we would need to see more of your original nomination to help you with advice on resubmitting. you said that you submitted the bench, so let me post the clarification on those:
if i were submitting the bench in your main photo, i would have the focus include less background, possibly cropped to square, more like the example photo in that clarification
for your supporting photo, i can barely see the bench so i would make sure to point out that it can be seen along with the sign in the supporting text. i might try a landscape oriented photo, and might even add an arrow like i did for this supporting photo
(you can’t edit your photos once you have submitted fyi. i take my photos before i begin my nomination so that i can choose the best one and make any adjustments needed before i submit. i submit with minimal text and edit and add links like the one you gave above to the supporting statement from my contributions page on the wayfarer site so that i can use my computer instead of my phone.)
