 RVs in the city of Spokane have to move every 24 hours. Just as Patchen said, Spokane's city code is as followed. A camper or RV is only allowed 24 hours to be parked on public roads. And after that 24-hour grace period, what comes next is this yellow impound notice. Now, what does this new Washington spring port ruling mean for Spokane's RV city code? But if we can't, if I can't get voluntary compliance, then unfortunately my only tool left is enforcement.
