- Study Area 1 (in orange) are the original proposed boundaries
- Include both Study Area 1 and Study Area 2 (in yellow)
- Include both Study Area 1, 2, and 3 (in magenta)
From what I've read, the most financially feasible is the 3rd proposal, and will most likely be what the new city will look like, assuming it passes public vote. This includes the Heritage Lakes development, the Heritage High School, Richardson's RV, the SoCal Edison Power Station, and parts of Romoland including Romola Farms.
Residents living in that part of Romoland will be included in the general vote for cityhood. There is a small effort in that part of Romoland to resist Menifee cityhood, and instead create a new future city called "Harvest Valley", but I don't think there's enough opponents there to make a significant impact on the outcome.
