The city council has determined that there are many elm and zelkova trees growing
on public and private premises within the city, the loss of which would substantially
depreciate the value of public and private premises and impair the safety, good order,
general welfare and convenience of the public. The city council has determined that
the health and life of such trees is threatened by a fatal disease known as Dutch
elm disease. The city council hereby declares its intention to control and prevent
the spread of such disease and the insect pests and vectors which carry such disease
and declares the Dutch elm disease and elm bark beetles which carry such disease to
be public nuisances.
