The trimming or cutting of oak tree species (Quercus spp.) for purposes other than protecting public safety should not be conducted between February 1 and June 1 to avoid transmission of the disease by insects. The resulting cut shall be treated immediately with commercial pruning paint to seal the exposed surface from contamination. Any wounds, whether made by trimming, construction, or accident, shall be treated immediately with commercial pruning paint to seal the surface from contamination. The Urban Forester may conduct unannounced inspections to ensure compliance with all provisions of this chapter.
