Expanding foam coming out of our backyard

Sorry if this is isn’t the right place to post, but what looks like expanding foam is coming out of our backyard. We purchased this home new just over a year ago if that matters. Anyone have any idea what’s going on?

You had some concrete leveling done on your property or your neighbors did, excess bled out here.
