Plantlife that overhangs any municipal improvement or grows in such a manner as to obstruct or impair the free and full use of any municipal improvement by the public may be considered a public nuisance. All plantlife shall be trimmed to provide for a minimum of seven feet (7') of vertical clearance above all sidewalks or activity trails and twelve feet (12') of vertical clearance above all streets or parking places. The enforcing authority may declare plantlife a public nuisance for reasons of disease and exotic characteristics. All plantlife that causes destruction of municipal improvements shall be considered a public nuisance. The owner shall be liable for all damages that are caused by plantlife to municipal improvements. (Ord. 2225, 8/9/05)
