RE: Ordinance 602

Utility Undergrounding Code Change

Dear Jenny:

My company owns property on Woodinville Duvall Road what will be affected

by the above ordinance, and I want to go on record as being in full support of

the ordinance to change the existing code.

Our property has preliminary plat approval from the City of Woodinville for a

13 lot residential development. The power for this development will be

provided by Puget Sound Energy (PSE), and preliminary plans reflect a need

for three electrical transformers. Under the current code, all of these

transformers will be required to be placed underground, and under the

above ordinance they would be allowed to be placed above ground subject to

certain screening and other requirements.

I have spoken with representatives of PSE about the undergrounding of these

transformers, and they have been very forthcoming about their opposition to

the existing code (undergrounding) requirement. The cost of the

undergrounding, the cost of maintaining the underground equipment, the

shortened life span of the equipment as a result and the added safety and

other complications of dealing with underground equipment in the event of an

emergency were all cited as reasons why this requirement should be

eliminated.

I watched the video of the Planning Commission study session on this topic,

and there was very articulate testimony by citizen(s), City staff and a

representative of the Master Builders Association, all in support of eliminating

this requirement.

One element that I would like to add in conclusion to this letter is a request

that this Ordinance, if passed, will be retroactive to include projects which

may have permit applications and/or approvals already in place but which

have not yet undergrounded their equipment as a result of the existing code

requirement.

Thank you.

Sincerely,

The Evergreen State Washington is known for its abundant trees in both rural and urban settings, which are vital to our quality of life. Trees provide us with wood products, wildlife habitat and watershed protection. They also provide shade, privacy, energy savings (both heating and cooling) and serve as windbreaks if properly placed. However, when trees are improperly placed or trimmed, they can become a hazard.

Help solve a growing problem and reduce outagesReliable electric service is vital to our quality of life. When tree limbs come in contact with power lines, electrical service can be interrupted. A large portion of power outages affecting Puget Sound Energy customers are caused by trees. Fallen trees and tree limbs that become entangled in lines, wind-blown branches that cross the lines as they fall to the ground, and tree limbs that grow into power lines are all major causes of outages. Not only are these service interruptions inconvenient for customers, they can also threaten public safety. Also, because the moisture in and on trees can conduct electricity, a tree in a power line can be extremely hazardous for anyone nearby.

A safe solution PSE operates and maintains two different types of electrical systems and a natural gas system.

Electric transmission lines transport high voltage electricity from power sources like dams and wind facilities to substations in local communities. Transmission normally takes place at voltages of 115 kilovolts (kV) or higher.

Distribution lines are critical links in the electrical system connecting substations and transformers directly to homes or businesses. Unlike transmission lines, distribution lines carry less than 69 kV. Distribution lines are installed both above and below ground.

PSE’s natural gas system is underground and special care needs to be taken when selecting trees to plant over this system.

In addition, tree planting recommendations are different for transmission lines, distribution lines and underground facilities.

Guidelines for planting

Guidelines for planting near underground natural gas and electric systemsUnderground utilities, including electric and natural gas lines, should also be considered prior to planting. The depth of underground utilities can vary, so it is important to plant smaller growing shrubs and ground cover within five feet on each side of the natural gas line or underground utility. To find out where underground natural gas and electrical facilities are located before planting, call 811 before you dig.

Guidelines for planting near 230 kV transmission lines Keeping the wire and border zones clear around transmission lines is the most effective way to reduce tree-related power outages.

• The wire zone is the area directly underneath the transmission line, extending about 10 feet on either side of the lines.

• The border zone is located along those portions of the rights of way not located directly beneath the transmission lines.

• PSE owns easements or has rights-of-way under most wire and border zones.

PSE will also remove any trees outside these zones that pose a risk of falling into the transmission lines.

To provide increased reliable service to our customers and respond to current standards of the North American Electric Reliability Corporation (NERC), the organization in charge of improving the reliability and security of the bulk power system in North America, PSE has adopted vegetation management standards for electric transmission lines with voltages of 200 kV or higher.

Due to these improved standards, PSE will remove any vegetation beside or underneath our 230 kV transmission rights of way that matures to a height of more than 15 feet. Tip

Guidelines for planting near 115 kV high voltage distribution lines and underground natural gas lines NERC vegetation standards do not apply to our 115 kV transmission or distribution line rights of way. Generally, PSE will remove trees that mature at a height of greater than 25 feet near high voltage distribution lines. However, some trees within the corridor with a height of greater than 25 feet, may be allowed to remain in the wire zone if they can be pruned in a manner that allows sufficient clearance from the lines.

Plan before you plantYou can help minimize power outages by simply taking care to select and plant the right sized trees at maturity near electric power lines, electric padmount transformers and underground natural gas lines.

To ensure reliable electric and natural gas service for the future, choose the right tree and best place to plant. Your wise decision now will support growth of easily maintained, healthy trees, and prevent future removal of mature trees. Careful tree selection should include how you plan to use the site, as well as area safety needs. When planting trees near buildings, look for opportunities to shield against hot summer sun and cold winter winds. If there are no utilities nearby, planting deciduous trees to the south and west of a building will help cool it in the summer and provide unimpeded natural warmth in the winter. Evergreen trees along the north side can also help slow down the affects of cold winter weather.

Since properly located trees can also increase your property value, taking care to plant the right tree in the right place is a wise investment. Properly planned tree planting also protects neighborhood streets and sidewalks, visibility and clearance, and prevents damage to pavement, sewers and buildings.

PSE has prepared this booklet to provide our customers with guidelines for sound tree management, placement and selection. Let the trees you plant today leave a legacy of beauty and safety for tomorrow.

Tools to help you plan your landscapingBefore planting trees and shrubs, consider what you want your yard to look like in 10 or 20 years. Then take an inventory of the factors that impact your site. Use a standard sheet of graph paper, map out your yard, house, driveway, street, type of power lines, underground padmount transformers, natural gas lines and other existing immovable elements. Consider where trees and shrubs can be added to complement your site.

How to plant trees and shrubsFirst, locate underground facilities. Washington state law requires local utilities be notified at least two business days before digging. Contact the Utility Notification Center at 811.

Dig the hole for planting two to three times the width and the same depth as the ball or container. Before lowering trees into the planting hole:

• For balled burlapped trees, place the root ball in the hole. Remove burlap, twine and wires.

• For container trees, remove the tree and straighten any coiled roots. Loosen the root ball.

• For bare-root trees, prune damaged or circling roots and plant during the dormant season. Keep roots covered before planting. Spread the roots and cover with soil, except in high clay or sand conditions.

Fill the planting hole with soil, covering the root ball. Avoid using soil additives like peat moss or composted organic material, except in soils heavy with clay or sand. Water well. Soak the root ball and surrounding soil. Repeat in three days. Mulch the area two- to four-inches thick, extending about two feet from the trunk. Keep the mulch away from direct contact with the lower trunk. Stakes can be used; however, it is best to stake only when necessary, as it may result in a weaker root system. Use strips of fabric or burlap, not wires or ties, to secure the stake to the tree. Remove stakes after the first year of growth.

98

Planting near padmount transformersWhen planting trees or other vegetation, be sure to allow the correct distance from padmount transformers.

A padmount transformer is a device that moves electricity safely from one circuit to another. It steps down the power (changes the voltage) so that it may be used in our homes and businesses. Because electricity flows through transformers, it is important to keep transformers clear of vegetation.

This diagram shows the minimum distances required when planting near padmount transformers.

Tips for safe planting around padmount transformers:• Keep in mind that the transformer must be accessible for service at all times

• Select plants that are easily maintained and suitable for the site

• Allow plants sufficient growing room

• Do not plant in front of the transformer (the side with the padlock)

• Do not allow plantings to grow over the transformer

• Avoid disposing of liquids through grates on below-ground transformers

• Do not change grade levels around padmount transformers

Tree selectionMost native trees and commonly used shade trees can grow to tremendous heights. Because of their great size, they do not fit well in the small spaces of many urban planting locations. Trees are often planted with little thought as to how large they will become once mature. These large trees are more likely to conflict with overhead power lines, sidewalks, buildings and streets. It can be difficult to imagine that the five or six foot tree purchased at the nursery will fit a space 80 feet tall and half again as wide. But large growing tree species in this climate will do that and well within our lifetime.

Sometimes trees are planted with the assumption that they can be pruned to keep them small. This can be very difficult with fast-growing plants, not to mention costly and time consuming. Ask yourself, if no one prunes this tree, will it become a menace? Selecting the right size trees can reduce, and even eliminate, the need for future pruning.

The Pacific Northwest climate supports a great diversity of plants. This booklet suggests only a few of the trees that can be grown in this area. Many more species are available. The following plant list has been prepared to help you select the proper size and species of trees and large shrubs for planting near utility lines or in restricted spaces. In addition to a mature size of less than 30 feet tall, these plants were selected for low maintenance, insect and disease resistance, availability, and beauty. The mature size listed represents the averages expected for our region. The actual growth of an individual plant will depend upon the soil, light exposure, moisture and temperatures of the site.

More information on planting and growing trees and shrubs can be obtained from the references listed at the end of this booklet.

PruningPruning is essential for the growth and well-being of landscape plants. The health of the tree is improved or maintained by removing dead, diseased, and damaged wood. The quality and quantity of flowers and fruit are increased with proper pruning.

Here is the general procedure for pruning trees:

A. Remove dead, diseased and damaged wood.

B. Remove or prune branches that are crossing other branches or growing in the wrong direction.

C. Thin, as necessary, to allow light and air into the center of the tree, and for even spacing of branches.

2120

When a pruning cut is made, the wound should be as small as possible. Before a branch is removed, locate the branch collar—the small fold of bark at the base of a branch where it joins the trunk. Make your cut just outside of this ridge (see diagram below). Cutting into the collar increases the wound size and the possibility of decay. To remove a large branch, undercut it first to avoid tearing the bark.

Recent research indicates that applying a wound dressing to the cut area is not necessary and may, in some cases, be detrimental to the tree.Tip

A

C

A. Make the first cut on the underside of the branch, sliding out from the branch collar.

B. Remove the entire branch with the second full cut from the top, just outside the undercut.

C. Remove the remaining stub by the third cut at the edge of the collar.

Dwarf Japanese Red Pine

Dwarf Japanese Red Pine – Pinus densiflora ‘Umgraculifera’ (also called Dwarf Tanyosho Pine)Mature size: 10-20 feet tallShape: When young, these trees grow with a crooked or leaning habit. With time, the habit becomes more vase-shaped, with wide spreading upward-arching branches. Description: This hardy species has exquisite decorative red-brown or orange bark. Plumes of rich green, three to five inch evergreen needles grow in twos. It can be used as a specimen or in groupings. It is quite heat tolerant, but needs well-drained soil.

(ii) Screening features shall not impose added external loading onto the buried utility facilities. The foundation or load supporting features of any screening features shall not be located in close proximity or directly on top of underground facilities.

 

Commented [KCR2]: I am concerned that, as previously written, conflicts will exist between the placement of structures in setbacks and compliance with WAC 296‐46B‐450. A minimum distance of 7’ will not fully contain a typical electrical enclosure within the 10’ frontage easement. 

Commented [KCR3]: If I’m reading this right, the publically operated facilities are not subject to landscape screening. If so, what makes these public facilities tolerable to exempt, while franchise utility features must be screened with landscaping? 

Formatted: Indent: Left: 1"

Commented [CKoo4]:  While a gas meter is not required to be screened by vegetation, as other utilities try to screen their aboveground features and apparatuses, some of the vegetation may be planted on top of or in close proximity to PSE buried natural gas service line. In accordance with the guiding material for the Federal Pipeline Safety Regulations (GPTC), … not to install service lines in close proximity to specific types of trees or shrubs which have extensive root growth, particularly the younger ones. Such growth could exert forces on the pipe and nearby joints. 

Formatted: Indent: Left: 1"

Commented [CKoo5]:  While a gas meter is not required to be screened by alternative screening method, as other utilities try to screen their aboveground features and apparatuses, the installation of these screening features may still impact our facilities. (1) If a fence is installed with the intention of screening other utility aboveground equipment but the fence unintentionally fenced off our meter, PSE and local fire department may now have issue accessing the gas meter for emergency response. In accordance with Federal Pipeline Safety Regulations, it requires gas meter must be installed in a readily accessible location. This is because (a) there are mandated maintenance regulations on buried and above ground gas facilities, and (b) emergency response including PSE personnel and fire department needs to have access to the meter, so they can shut off the meter and gain control of certain emergency conditions. (2)If a screening feature is installed on top and perpendicular to our gas service, the feature may impose additional external loading to the service line and potentially damage our facilities.
