Typically late May, set each year by City Council resolution. Owners receive written notice by mail approximately 30 to 60 days in advance.
What if my lot is a chronic illegal dumping target?
Installing a fence, cameras, no-trespassing signs, and lighting can reduce incidents. The city will still cite the owner if dumping accumulates, but good faith security measures are considered in penalty decisions.
