MAINTENANCE AND PLANTING OF PARKWAY TREES
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 Parks, Beaches and Recreation Department will trim the parkway trees
on a rotation schedule. An effort will be made to trim most of the
parkway trees on a two year cycle. If the rotation trimming is completed
in less than two years, more frequent trimming will be done 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 on the Peninsula and parts of Corona del Mar during
the fall and winter due to heavy traffic during the summer. 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 Parks, Beaches and Recreation Department to
determine species for planning purposes in all new subdivisions and
replacement in established parkways.

a) 25 feet back of beginning of curb returns at
intersections.
b) 10 feet from lamp standards.
c) 10 feet from fire hydrants.
d) 10 feet from service walks or driveways. •
e) 10 feet from meters and sewers.
f) 25 feet from stop signs.
C. Trees shall be a minimum container size of 15 gallons.
1. Condition: Plants shall be symmetrical, typical for variety
and species, healthy, vigorous, free from plant disease,
insect pests and shall have healthy, normal root system free
from being root bound. Trees shall not be pruned or topped
prior to delivery.
2. Inspection: All plant material shall be subject to inspection
and approval by the City prior to planting. The City has the

PARKWAY TREE PLANTING
A. All pits shall be dug with bottoms level, the width equal to two
times the diameter of the ball, and the bottom two times the depth
of the container from which the tree is planted.
B. Pits shall be backfilled with a thoroughly mixed "prepared soil" to
the bottom of the tree ball. When planting tablets are required,
they shall be placed after placing the tree ball in the pit. Five
21 gram) planting tablets shall be evenly spaced around perimeter
of pit on top of prepared soil.
Note: Where land developers are required to provide soil analysis,
the prepared soil backfill shall be based on test results.
C. When soil analysis is not a requirement, "prepared soil" mix for
backfill of the pits for 15- gallon trees shall consist of 758 native
soil and 258 nitrolized fir sawdust.
Note: (1) Nitrolized Fir Sawdust shall have a minimum nitrogen
content of .78.
2) Planting tablets shall be a commercial fertilizer in
tablet form yielding 208 nitrogen, 108 phosphorus and 58
potash. The tablet shall be compressed and yield a slow
release of nutrient over a 12 -month period.
D. Set plants in center of pit, in vertical position, so that crown of
ball will be level with finish grade after allowing for watering and
settling and shall bear the same relationship to finish grade that
it did to soil surface in original place of growth.
E. Prepare a depressed water basin capable of holding 10 gallons of
water. Water shall be applied in that quantity at time of planting.
F. If houses are not occupied, trees shall be watered one week later.
Thereafter, watering shall be done at one week intervals by the
developer for a period of one year or until homes are occupied.
G. Each tree must be properly supported by two Lodgepole pine stakes or
other material approved by the City. Stakes shall be a minimum of
eight feet in length. Stake all trees at time of planting by
placing stake in prepared hole and driving stake a minimum of 30
inches into soil.
H. All trees shall be secured to stakes with a cinch tie.
1. Eight penny duplex nails shall be used to secure the brace to
the stakes -- two per side.
