G -6
The City Council is vitally interested in beautification of City parkways. Public
cooperation in helping to develop and maintain healthy and attractive trees is
encouraged.
MAINTENANCE OF PARKWAY TREES
The General Services Department will trim the parkway trees on a rotation
schedule. An effort will be made to trim the parkway trees on less than a three
year cycle. If the rotation trimming is completed in less than three years, more
frequent trimming will be done performed on certain trees and in view areas.
Public safety such as low branches and heavy foliage will be given priority over
view trimming. An effort will be made to trim parkway trees located in heavy
summer traffic areas during the fall and winter months. The trimming schedule
will be altered to avoid trimming streets with flowering street trees during their
blooming time. This will apply to streets having a large number of flowering
trees, not to one or two trees on a street.
TREE LIST
The Parks, Beaches and Recreation Commission has adopted an official tree list
which will be used by the General Services Department to determine species for
planning purposes in all new subdivisions and replacement in established
parkways. The list will be reviewed on an annual basis by the General Services
Department staff with any recommendations forwarded to the Parks, Beaches
and Recreation Commission.
