Liberty Lake was officially incorporated on August 31, 2001. This was done after four previous attempts. The incorporation action drew boundaries based on prior neighborhoods voting positively. Those neighborhoods were then selected for the subsequent incorporation vote. This is why the Lake itself is not in the city as long-term residents are generally against the direction the city has taken. See City of Liberty Lake, Washington.
