Tree roots do not cause drains or sewer pipes to break, but they will invade and clog drains that have pre-existing cracks and resultant leakage. Drains are usually six to eight feet below ground level, while tree roots grow almost exclusively in the upper two feet of soil, because they not only need nutrients, but also oxygen to survive.

It is very unusual for roots to physically break drains and associated pipe work. However, tree roots are opportunistic and if an old pipe with poor joints is leaking into the surrounding soil this will attract the roots that may then exploit the existing weakness. Then, when repairs are required, a proliferation of tree roots often leads to the blame being placed with a nearby tree.

When homeowners suspect they have a blocked sewer line between their home and the main City sewer, they should contact Toronto Water for assistance: 416-338-ROOT (7668). First response to sewer line blockage, inspection and emergency repair service will be provided by City staff 24 hours a day, seven days a week. After normal business hours, response will be limited to emergency situations where the sewer service lines are completely blocked.

SpamCop automatically handles blocking and unblocking of ISPs. If SpamCop continues to receive reports of spam originating from the networks you are responsible for, those networks will continue to be blocked. If not, then you will be unblocked by SpamCop automatically after 24 hours. If the SpamCop reports that you receive relate only to web-hosting for the spammer, then this does not count toward blocking. The email filters consider only complaints of sourcing spam.

A City citizen ad hoc committee determined, for environmental reasons, that only a certified arborist could make the determination as to whether a City tree would be removed. Telephone us at (626) 858-7294. The staff member answering the telephone will take the information and prepare a work order. A Supervisor will contact our arborist that will make the final determination. The Supervisor will notify you of the arborist's decision.

The City’s tree policy outlines the criteria for removal of City street trees. If your tree does not meet those criteria you can appeal staff’s decision to the Park & Recreation Commission. The appeal form is available on the City’s Web site.

A tree is only removed that is dead, dying, structurally unsound or if it creates a problem that cannot be resolved without causing great harm to the tree. Trees are inspected and the decision to remove is made on a case-by-case basis.

a resident, you do not have a 'legal right' to light that may be blocked by trees. However, we do consider light to people's properties when we inspect trees. We prune all roadside trees and trees in grassed areas (that are our responsibility) every 5 years. Generally, we do not prune trees on request as this would cause problems with funding for our pruning programme.

If the damage is located within the City owned street allowance, there is no liability against the City to pay for these claims. If the damage is on private property, claims are investigated individually to determine the City's liability.

The planting, care and maintenance, protection, preservation and removal of all trees located on any City street shall be under supervision of the General Manager of Parks, Forestry and Recreation. No person shall remove, cut down, destroy or injure any tree or part of a tree located on a City street except with the prior written approval of the General Manager.

A parkway tree may not be removed due to intrusion of tree roots in a private sanitary service line. Sanitary service lines, which have been intruded with tree roots, are considered defective and must be repaired. All costs relating to repairs and maintenance of private sanitary service lines are the responsibility of the property owner. No. The Street Division of the Public Works Department maintains approximately 65 miles of local streets.

To qualify for Tree City USA, a town or city must meet four standards established by the Arbor Day Foundation and the National Association of State Foresters. These standards were established to ensure that every qualifying community would have a viable tree management plan and program. It is important to note that they were also designed so that no community would be excluded because of size. Please visit our Tree City USA pages for information on these standards and to download an application.

Each home or commercial building has a separate connection to the public sewer main called a sewer lateral. Under current Municipal Code, Section 14.36.050, it is the property owner's responsibility to maintain and repair the sewer lateral up to the point of connection with the public sewer main. This includes both the portion on private property and the portion located beneath the sidewalk and street.

This varies from patient to patient. The drain must be removed through a small incision at the side of the chest. As it is removed the incision is stretched for a moment causing some brief pain. Most tolerate this with little problem; a few complain that it does hurt, but it subsides very quickly.

Most people know that tree roots stabilize a tree. However, that is only part of their job. Most people don't realize that roots absorb oxygen out of the soil. Tree roots absorb air, water and nutrients such as nitrogen, potassium and phosphorus from the soil then convey these elements to the rest of the tree. All of these are essential for the trees growth and overall health. Tree roots also store starches that are produced during the growing season.

Build decking or benching around trees, to relieve pressure on the roots. Install other plants around the base of the tree to divert traffic. Put in more trees and spread out the love!

The growth characteristics of many species is to develop surface roots. Silver maples are one example. Many times, surface roots occur when the tree roots are looking for water, the soil is too hard, or the soil is saturated with water. Surface roots can impact sidewalks and driveways.

Generally, tree roots get into sewer lines because they are old and leaking and need to be replaced or repaired. It is rare that tree roots will crush a sewer line. If this occurs, please call the Urban Forest Section to have someone inspect the damage.

YES. The hopper on the TURF RAKE can raise to a height of nine feet so the unit can even dump into high sidewall dump trucks.

If the Inspector determines that a flag's defects are only due to tree roots, and that there are no other non-tree related defects on such flags, then these flags will be replaced at no cost if the City replaces your sidewalk.

The Diamond Point Club tracts have no flood control maintenance oversight. Unlike newer developments, where separate parcels contain county-owned or 'common area interests' for utilities and flood control, each section of drainage canal and down spout passes through the property of individual Diamond Point owners. This means that each property owner is responsible for the maintenance of each part of the total system.

Tree roots can normally grow to that of two and one-half times the height of the tree. The area under the canopy of the tree is commonly referred to as the critical root zone. The amount of critical root zone lost is directly related to the amount of die-back in the crown of the tree. In an oak tree, if more than 30 percent of the critical root zone is lost, the tree will die. However, soft wood trees, such as box elder, can tolerate far more root disturbance.

We receive approximately 800 requests per year for tree removals. Those that pose the most critical needs will be prioritized and removed first.

We have no evidence nor reports that they are more of a menace than any other species of tree but feel that no tree should be planted near sewage drains and this is especially true for fast growing trees.

No, the wetting and drying of the clay soil causes the initial cracks. After these have developed, tree roots will grow into the cracks for moisture.

Roots grow toward water vapor or moisture, by a continuous process (hydrotropism) occurring at the very end of the root. The root grows one cell at a time enabling it to enter the small cracks and joints, which may be present in your pipe. After a root enters a pipe, it divides hundreds of times to form a large mass of tender root ends. This root mass will accumulate a thick coating of grease which will collect up on the root mass until a blockage occurs.

No. In six years of controlled use, there has been no indication of damage caused from the spike or cross member entering the root ball. Any piercing will, at worst, cause the roots to grow around the impediment.

Cracks in the driveway may be caused by water and age in addition to roots. PBC Forestry recommends that the surface be removed so the roots can be inspected before condemning a tree. Frequently the cracks are caused by small surface roots that can be removed prior to the new surface being laid.

Tree roots are opportunistic. While they will not crack a sound sewer service or water line, they will exploit cracks or failures in the lines. The best defense against having tree roots in lines is to make sure that your lines are in good condition and that they're not cracked. If you suspect that tree roots are growing into your sewer line, you can have the roots cut out using a process called "rodding".
