Hello and welcome @scarletspeed21
It is very natural to get frustrated when you visit some places and see lots of pokestops and gyms and yet there are very few around where you are.
This sometimes happens. In areas that are clearly residential focussed., especially developments in the USA, there is very little other than housing, and single family residential property is just not eligible. Pokémon Go has chosen this method of using real places to reflect in game activity. You need to work with it.
@DTrain2002 has given a lot of information about what is acceptable so do read that.
What @Trollfarer has pointed out is that some of your attempts to get stops are showing as objects that are not there. The deep frustration and sense of unfairness you are feeling has drawn you to try and create pokestops that are fake in order to get what you want to make the game playable. Please don’t do this. It is viewed as a serious issue by Niantic and it can result in you losing your Pokémon go account. In other words in trying to make the game better to play you may not be able to play at all.
What you can do.
You can start again but this time try to work with what you do have and some help and support from experienced wayfinders. There is a lot to learn so be willing to learn.
This article is very helpful about what makes a good nomination.
You have said you have spoken to the HOA. What exactly was their response? Are they willing to help improve the area?
A simple picnic area with picnic tables and maybe a communal fixed BBQ or fire pit would all be good. No need for a more expensive large pavillion ( although that would be excellent)
Were they receptive to creating an exercise walking route?
Some information boards about wildlife at ponds?
I’m going to move this to nomination support and I’ll tag @BlameJamal who likes nothing better than to look at an area for ideas.
We are happy to offer a helping hand and good advice, p,ease take it.
