Yeah, those permits for the office trailers on the "Project 304 Site" are the first public mention of the project number for what I assume to be the new resort.
I don't want to get anyone in trouble by naming specific names, but a few people already have "Project 304" listed on their resumes/websites, and it's very easy to find them with a quick Google search. For example, the job title JungleSkip posted comes from someone's LinkedIn profile. Additionally, there's another person who has done work for tons of other themed entertainment projects that lists "Universal - Project 304" on their clients page under
Roto which is a huge Design/Build firm, so they're definitely involved with the new resort as well.
There's also a couple of other permits that have been filed with Orange County for the mass grading of the new land. The first one (18-MGF-0032) was for the grading of the 100 or so acres for the warehouse space and new offices. The second one (18-MGF-0033) is for the mass grading of around 425 acres. The second permit is definitely for the "Project 304 Site", as it contains the land where the trailer complex is being built. I've included a shot of the permit as well as the parcels it applies to below:
So yeah, they've definitely already got the gears in motion for the new resort.
