[R.O. 2008 § 402.080; Ord. No. 5752 § 1, 12-8-2011]
A.
Where record plats have been approved in
a subdivision prior to November 1, 2001 without an approved landscape
plan, said plat shall conform with the ordinance requirements in place
at the time of approval which typically required the installation
of one (1) tree per fifty (50) feet, or portion thereof of street
frontage, public or private, within an area between the front of a
structure and the curb. Said trees can be clustered or arranged within
the setback and need not be placed evenly at fifty-foot intervals.
B.
For residential subdivisions approved between
November 1, 2001 and the adoption of this Article there shall be a
minimum of one (1) tree for every lot; in cases of lots having frontage
on more than one (1) street (e.g., corner lots, through-lots), there
shall be a minimum of one (1) tree for each street on which the lot
has frontage, unless the developer and/or homeowners association has
established a landscaped buffer along the street frontage. Each tree
shall be at least two (2) inches in caliper at planting and must meet
the definition of a "tree" at maturity.
C.
Prior to the adoption of this Article,
City codes had allowed trees on lots to be placed within the City
right-of-way, specifically between the sidewalk and back of curb.
It has been observed that this has caused damage to City and private
infrastructure as well as sight-distance issues, safety issues and
property damage. Unless otherwise provided by this Code, trees will
no longer be located within fifteen (15) feet from back of curb. City
codes still require one (1) tree to be located within each lot and
two (2) trees if located on a corner lot.
[R.O. 2008 § 402.090; Ord. No. 5752 § 1, 12-8-2011]
One (1) tree for every forty (40)
feet, or portion thereof, of street frontage, public or private, shall
be required within the landscape setback abutting said street frontage
(as determined by the type of roadway). Said trees may be clustered
or arranged within the setback and need not be placed evenly at forty
(40) foot intervals. In addition to the required trees, based upon
street frontage, one (1) tree shall also be required for every three
thousand (3,000) square feet of landscaped open space. These may include
the trees required in parking lots as set out in this Chapter. Trees
along the roadway shall conform to the tree standards set forth elsewhere
in this Chapter.
[R.O. 2008 § 402.100; Ord. No. 5752 § 1, 12-8-2011]
One (1) tree for every forty (40)
feet (or portion thereof) of street frontage, public or private, shall
be required within the landscape setback (as determined by the type
of roadway) and need not be placed evenly at forty (40) foot intervals.
In addition to the required trees, based upon street frontage, one
(1) tree shall be required for every four thousand (4,000) square
feet of landscaped open space. These trees may include trees required
in parking lots as set out in this Chapter. Trees along the roadway
shall conform to the tree standards set forth elsewhere in this Chapter.
[R.O. 2008 § 402.110; Ord. No. 5752 § 1, 12-8-2011]
A.
Minor Residential/Local Access Road.
1.
One (1) tree shall be located in
the front yard of every lot, unless on a corner lot in which case
a tree shall be located on the frontage of each side as required per
the zoning district.
2.
No trees are to be located within
the right-of-way, following the standards set forth in this Chapter.

C.
Medians For Collector And Minor Arterial
Roads.
1.

(7) feet in width.
2.
If trees are planted in the median,
the tree spacing will be based on the type and size of tree or shrub.
3.
No trees shall be located within
twenty-five (25) feet of the median tip or within the intersection
line of sight, whichever is greater. No trees shall block the line
of sight for a traffic signal.
4.

collects and removes gravitational water from the pavement and root
zone area eliminating seepage to the road surface.
9.
Tree Planting In Roadway/median Landscapes.
If the landscape planting is to support tree growth above eight (8)
feet in height, the root zone supporting the landscape plantings must
be excavated below pavement grade to a point below that interfaces
the root zone mix with the soil below the road bed. Pavement, concrete
rubble, gravel, etc., that restricts or limits root growth is prohibited
from the root zone area.
D.
Sight Triangle And Obstruction. On the
point of any access onto a public street or the intersection of any
two (2) streets, development shall conform to the requirements of
the sight triangle in which nothing shall be erected, placed, planted,
or allowed to grow in such a manner as to materially impede vision
between a height of thirty-six (36) inches and fifteen (15) feet above
the grade at the back of the curb of the intersecting streets, within
the triangular area formed by the right-of-way lines and a line connecting
them at points twenty-five (25) feet from their point of intersection
or at equivalent points on private streets or as otherwise shown on
the approved site plan.
[R.O. 2008 § 402.120; Ord. No. 5752 § 1, 12-8-2011]
The necessary agency must be contacted
for their review of any trees to be located within their right-of-way.
If acceptable, the trees must meet the minimum requirements and tree
type set forth in this Chapter.
[R.O. 2008 § 402.130; Ord. No. 5752 § 1, 12-8-2011]

Tree standards in common ground or on private
property:
[R.O. 2008 § 402.140; Ord. No. 5752 § 1, 12-8-2011]
A.
Plant Material Selection, Handling, Inspection,
Storage And Planting.
1.
Only desirable, long-lived trees
of good appearance shall be planted on public sites. All trees shall
have reasonably straight trunks with well developed leaders and tops.
All plant material should be free from insects, diseases, wounds,
and cankers. Trees planted shall be adaptable to USDA Zone 5 climate
conditions. There must be a well developed root system and root ball
must be moist. Root balls must be protected from freezing.
2.
Trees should not be picked up by
their trunk. The soil ball should be supported when moving the tree.
Trees should be protected during transport and kept cool and moist
at all times.
3.
All trees must adhere to the Standards
for Nursery Stock.
4.
The City has the ability to reject
any and all nursery stock.
B.
Tree Planting. Missouri law requires that
a locate request be placed before beginning any excavation. Place
a locate request by calling 1-800-DIG-RITE (800-344-7483). The utilities
should respond to your request and mark the approximate location of
their facilities within three (3) working days. You can then proceed
with your excavation avoiding damages.
C.
Planting Procedures For Potted Or Balled
And Burlapped Trees.
1.
Optimal time for planting trees is
the fall or early spring, when the tree is dormant. Planting trees
at other times is discouraged due to increased stress on the tree.
If you have any questions on planting times contact the O'Fallon Parks
and Recreation Department.
2.
The hole should be dug with the width
three (3) times the spread of the root ball no deeper than the root
ball. Holes should have slanted sides and be roughed with a shovel.
(2).tif.png) |
3.
Trees will be planted no deeper than
the original root flare. Do not confuse a graft union for the root
flare. In clay soils trees can be planted slightly high. Excavation
and soil replacement may be necessary where there is overlay compacted
subsoil and excessive amounts of gravel.
4.
Remove tree from pot or cut away
twine or rope from stem and wire basket below ground level. When possible,
roll back burlap from top and cut off top one-third (1/3) of the wire
basket. Always remove all plastic twine and artificial burlap.
5.
Straighten tree and completely backfill
hole with existing soil. Avoid using excessive amounts of organic
matter.
6.
Apply water to settle the soil and
eliminate any voids. At this time a solution of root stimulator (not
fertilizer) can be watered in.
7.
Chop up any dirt clods; add soil
if needed.
8.
Place a two (2) to four (4) inch
layer of mulch around the tree in a minimum three (3) foot radius.
Make sure that the mulch is not mounded against the base of the tree
trunk.
