I created too big of a city and now it crashes when I zoom in close (around 80% I think)

As the title says, I created a large city using premium assets and some uploaded images (I have been making the file sizes smaller to see if it helps) but it still crashes when I zoom in to around . Is there a way I can fix this without having to redo all of my work? 

Here are some steps to try out when this happens: Try accessing the game through both Chrome and Firefox. If an "unresponsive script" prompt pops up, try letting things sit for several minutes. If the game still fails to load, answer the prompt such that the "unresponsive script" stops. If the Player Ribbon is on a different Page, you should be able to solve this by promoting another account (e.g. a player or somebody else you trust) to GM. Afterwards, that person should be able to access and edit the Page Settings of the Page in question, or remove images from the page. Please let us know how this goes; if none of this works there are additional steps that can be taken.
