So I’m trying to get a Gym added at our local park. I already completed the first step by getting one PokéStop approved and added into Pokémon GO.
Recently, a second PokéStop at the same park got accepted, but it still isn’t showing up in Pokémon GO even though the nomination was approved.
Does anyone know why this happens or how long it usually takes for the second stop to appear? I’m trying to get the area upgraded into a Gym.
Welcome to the forums 
If it has been more than 48 hours since the wayspot was accepted, it might be blocked by being too close to the first wayspot.
If you want to post the location, it will be easy enough to check - and maybe also someone will look around to see what else might be eligble 
not to sure how to send locations on computer sorry
well how can i move it a tad bit so it can get accepted i just wanted it to be close so it could be a gym
If it has been accepted in a correct location then you can’t move it.
Moving for game reasons is classed as Abuse and can lead to suspensions on Wayfarer and GAMES accounts.
If you still have the email that was sent when you fist nominated then the co-ordinates will be included there.
The coordinates are below the second photo in the initial “submission received” email. They will look something like 34.21823, 10.21783
fixed it take a look at it
As assumed these are both in the same cell, therefore only 1 will be used in game.
I will repeat, DO NOT attempt to move a correctly placed nomination, it’s not worth risking your accounts.
Maps are out of date but with all the new construction I am sure you can find something else…
The following shows the L14 cell (large red). If you find anything in this area that is in the small red cell (L17) then it should trigger a Gym.
If the Swimming Pool is not just for a single family then that should be eligible.
Is there a Church or “Village Hall” building.
Anywhere that is to bring people together?
All the mentions of Trails, are there any signed walking trails?
Picnic Area?
The lake itself will not be eligible but is the anything there, Fishing Pontoons etc.
Good Luck.
If you are willing to walk both these L14 cells only require another nomination to trigger Gyms.
But if the OP wants to be a bigger hero…
They may want to explore these areas to see if there are other nominations they can submit.
