All unpaved spaces of ground between the property line on any street or public place,
and the sidewalk abutting thereon or along the same, and all unpaved spaces of ground
between any such sidewalk and the curb are declared to be public grass strips and
shall be under the immediate control, care and keeping of the owners or occupants
of the premises abutting thereon, and such owners and occupants shall be held responsible
for the care and preservation thereof, and they shall sow grass seed or place sod
thereon and carefully mow the grass thereon whenever it has attained a height of ten
inches; and they shall see that there is no accumulation of paper, trash, filth or
dirt thereon. Property owners shall be permitted to plant flowers and shrubs in the
public grass strips wherever the width thereof will permit this to be approved by
the Street Commissioner for the protection of flowers, grass, shrubbery of flower
seeds planted in the public grass strips. The Street Commissioner may also grant permits
to abutting property owners to plant trees of an approved kind in any of the public
grass trips where, in his judgment, the strip is sufficiently wide to allow trees
and they will not injure the street paving, sidewalks or sewers, but only such trees
as shall be approved by the Street Commissioner shall be so planted. No hedges exceeding
18 inches in height shall be allowed in any public grass strip and if any hedge is
planted in any such strip, it shall always be kept neatly trimmed and vacant spaces
replanted by the abutting property owner or occupant. No public grass strip shall
be lowered below the grade of the sidewalk except by permission of the Street Superintendent.
