Subcommittee Objective

To identify methods to address infrastructure damage caused by street

trees in PUDs:

•approved prior to the 2011 amendments to the ULDC

•with public rights-of-way (maintained by PBC) less than 50 feet in width

Options / Recommendations for Discussion

To minimize future damage to infrastructure the following options should

be considered when trees are required to be replaced:

•root barriers - effectiveness

•Informational Plant List - limitation on the size / type of that can be

installed

• Installation – verify proper procedures are followed and proper

materials and products are utilized

History of Street Trees in

Palm Beach County

Prior to 1992 street trees were either installed by developers, with no

approval, or conditioned to have them installed by Board of County

Commissioners (BCC).

In 1992 street trees were required by code. Developers did not

always provide plans to PBC Land Development prior to installation

of the street trees. The Developers would provide an as built street

tree plan at the end of the project, prior to Land Development

signing off.

In 1997 Palm Beach County Land Development section started

requiring the submittal of street tree plans. Plans are submitted,

reviewed, approved and trees installed accordingly.

Once concrete was removed it was

obvious that proper precautions

weren’t taken. Why is there no

damage to the side walk due to it’s

location to the tree?

Page 32: Street Tree Requirements - Palm Beach County, Floridadiscover.pbcgov.org/pzb/zoning/Hearings-Meetings-LDRABSub/LS/20… · 2012-12-12  · 2000 ULDC - Article 3.E.1.C.2.d • Concern

Here we have a problem with a side walk –

the cause the tree roots. Remove the

sidewalk (problem) and see if anything can

be done with the cause.

Root barriers can deflect

roots

• Barriers have been placed vertically in the soil to deflect roots away from hardscapes

• Place the barriers sufficiently away from the structure (about six inches) to be protected so that as the roots grow wider they will not touch the curb or walk

• Be sure the top of the barriers reaches above the top of the soil so roots do not grow over it

Root barriers can deflect

roots

• Roots are deflected horizontally and down by most of the barriers on the market

• In compacted soils and soils with a high water table, roots grow under the barrier and up the other side

• In well drained soil, roots may remain at deeper depths longer

Install alternate sub-base

material

• Layer of washed gravel installed as sub-base material -roots remained under the gravel (left)

• Roots did not grow directly under the slab as they often do when a sand, limestone, or no sub-base is used (right)

• Gravel installation helped prolong the life of sidewalks

Defects & Effects

Aggressive surface roots

from deep planting

• Excavation (using an air spade) of root collar on trees planted too deeply can show severe defects such as these

• If this tree does not currently show above ground symptoms, it is likely to soon

Root Flare

Root flare on forest grown

trees

• Root flare causes no problems where there is adequate soil space for expansion

• Note the abundant flare at the base of all these trees

Root Flare

Root flare can destroy

infrastructure

• Roots at the base of certain trees become extremely large and can displace curbing, sidewalks, and pavement

• The curbing and pavement were lifted by up to two feet next to each of the trees on this street

Big island means

healthier trees

• Here is a parking lot constructed on a compacted clay soil

• The two trees on the left and center (blue arrows) are larger and darker green than the tree on the right

• The stressed tree on the right was planted in a tiny island whereas the healthier ones were in a larger island.

Small trees for small islands

• Small-maturing trees such as crape myrtle are the best ones to choose for small islands

• They cause less damage to hardscape than trees that grow to be large

Defying reason?

• Occasionally, trees appear to be defying reason, i.e, the tree appears healthy and the pavement is intact

• There can be several explanations for this:– pavement might have been

added under the tree recently

– the soil under the pavement may not have been compacted well

– specially designed structurally soil may be present under the pavement

– the existing soil may be gravelly

– luck
