You spend 20 years asking your city council to block new housing. You were successful.
Then, when the RVs show up, you are upset that they don't live in the apartments you prevented.
If you don't like it, look in the mirror. There's the guy who caused the problem.
Block new housing? Or block low income housing that will destroy the community AND your property value? Look in the mirror and realize your party's attempt at buying votes, by helping a guy making $23k a year live in a $1.5M neighborhood, only helps $23k a year guy.
