Based on personal experience with California planning commissions and septic contractors, I’m guessing this will be fixed shortly after the greens take up arms and capture a few nuclear missile silos for the the new nation of the Free Pacific States.
Alternatively, people could, I don’t know, take Sewage Systems 101, or maybe read a book before getting licensed or setting up regulations.
Edit: If you’d like to learn more about a literal shit slide slowly working its way down to the Santa Cruz beaches, read up on all the political maneuvering around re-certifiying septic systems in the CZU burn scar.
