As an alternative, ornamental trees intended to grow to less than 35 feet in height: minimum spacing of 20 feet and maximum spacing of 30 feet.
(3) 
As an option if approved by the Board of Supervisors and subject to approval of a final planting layout, street trees may be clustered at the corner of the property line and right-of-way, provided that the required density is satisfied and site lines and lighting are considered in the layout (see Figure STT-2).
(4) 
Street trees should be located between the sidewalk and the paved cartway of a street in the "tree lawn," provided that trees shall not be placed in swales or berm areas beside noncurbed streets.
B. 
Branching standards.
(1) 
Street tree branching shall not interfere with clear sight triangles. At intersections, trees shall be located so that their foliage is no closer than 35 feet from the intersection of the streets' right-of-way as measured from a height of two feet to six feet (see Figure STT-3).[2]
[2]
Editor's Note: The Street Tree (STT) Figures are included as an attachment to this chapter.
(2) 
Typical branching of street trees shall not be within eight feet of ground level after 10 years (see Figure STT-3).
(3) 
Plantings shall not interfere with clear visibility to pedestrians or with free passage on sidewalks and trails. A three-foot clear zone shall be maintained from a height of three feet to eight feet (see Figure STT-3).
C. 
Tree quality control.
(1) 
Trees shall be nursery-grown in a climate similar to that of the locality of the project. Varieties of trees shall be subject to approval of the Board of Supervisors.
(2) 
All trees shall have a normal habit of growth and shall be sound, healthy and vigorous. They shall be free from disease, insects, insect eggs and larvae.
(3) 
The trunk diameter of all trees, measured at a height of six inches above finish grade, shall be a minimum of two inches in caliper.
(4) 
Requirements for the measurements, branching, grading, quality, balling and burlapping of trees shall follow the code of standards recommended by the American Association of Nurserymen, Inc., in the American Standard for Nursery Stock, current edition.
D. 
Tree selection.
(1) 
Street trees shall be of a type which will comply with standards of this section, whose root structure is not such as will cause damage to paved streets and/or sidewalks, which are hardy to the local climate and which do not have invasive characteristics.
(2) 
Street trees shall be selected from those recommended from Street Tree Fact Sheets published by the Municipal Tree Restoration Program or the Directory of Landscape Tree Cultivars Project, School of Forest Resources, Pennsylvania State University (1993 or current edition). Unless deleted from said sources' current editions, suitable tree species shall include:
Species
Common Name
Acer rubrum
Red maple
Acer rubrum "Red Sunset"
Red Sunset maple
Acer freemanii "Autumn Flame"
Autumn Flame
Acer freemanii "Celebration"
Celebration maple
Fraxinus americana "Autumn Purple"

Fraxinus pennsylvanica "Summit Ash"
Summit Ash
Gleditsia tricanthos inermis
Sunburst honeylocust
Tilia cordata
Littleleaf linden
Zelcova serrata "Green Vase"
Green Vase zelkova
(3) 
Other tree species may be used, subject to Township approval, provided that information acceptable to the Township is provided which indicates that the species would comply with standards of this § 29-46.
(4) 
Trees which are known to have invasive characteristics which may escape and spread are to be avoided. No trees included on the list of "Invasive Plants of Pennsylvania" published by the Department of Conservation and Natural Resources (current edition) are authorized.
(5) 
Among others, the following species of trees are prohibited (those marked with an asterisk having cultivars not known to be invasive):
Species
Common Name
Acer platanoides
Norway maple*
Acer pseudoplantanus

E. 
Tree planting implementation.
(1) 
All planting shall be performed in conformity with good nursery and landscape practices and to the standards established in this section.
(2) 
Planting shall be completed during normal planting seasons of the community.
(3) 
Street trees are to be maintained and guaranteed for a minimum of one year after completion of planting. If, during the guarantee period, more than 1/3 of the tree dies, the tree shall be replaced. Replacement trees shall conform to all requirements of this section and shall be maintained and guaranteed for a minimum of two planting seasons.
(4) 
Excavation. The planting pit shall be excavated so that the bottom of the root ball of the tree will be six inches above the undisturbed soil and the top is approximately three inches to four inches above finished grade. Excavate with sides vertical and scarified and with the bottom flat. The planting pit should be over-excavated to allow for 18 inches of loose topsoil on either side of the root ball (see Figure LD-1).[3]
[3]
Editor's Note: The Landscape Planting Details (LD) Figures are included as an attachment to this chapter.
(5) 
Backfill. Backfill with native or imported soil that matches the characteristics of the indigenous soil. Imported soil must be free of rocks larger than two inches in diameter and of clay, toxic matter, plants, weeds, roots and/or any other debris deemed disadvantageous to proper plant growth (see Figure LD-1).
(6) 
Planting. Planting standards generally are as set forth in Figure LD-1 and also include:
(a) 
A six-inch layer of planting soil shall be placed and compacted in the bottom of the planting pit.
(b) 
After plant is set in planting pit, retain burlap on the root ball but pull away from the main stem of the plant.
(c) 
Place backfill in layers four inches to six inches thick and work each layer by hand to compact the backfill and eliminate voids. Ensure that the plant is plumb.
(d) 
Once backfill is approximately 2/3 complete, saturate with water and repeat until no more can be absorbed. Remainder of backfill should then be placed and compacted and watered again.
(e) 
Form a watering saucer around the trunk, and mulch with two inches to three inches of double-hammered aged bark mulch.
(f) 
Bark mulch should not be placed against base of tree trunk.
(7) 
Pruning. Dead or broken branches are to be removed. The tree should be pruned to encourage natural growth consistent with the species planted.
(8) 
Staking and guying. Hardwood stakes shall be driven into firm soil outside of the planting pit, using #12 double-stranded wire with a length of rubber hose to ensure protection of the tree trunk. The wire is to be tightened by wrapping it around a stake (see Figure LD-1).[4]

A. 
Traffic signs. All required traffic signs shall meet the requirements of PennDOT Publication 236M for Type 3 signs.
B. 
Street marker signs.
(1) 
Two street markers shall be erected at each intersection of two or more streets.
(2) 
The streets signs shall be of corrosion-resistant aluminum and shall measure approximately 22 inches by four inches. They shall have four-inch-high Scotchlite™ white letters on green background. The signs shall be furnished from a Township-approved source complete with aluminum caps and rustproof fittings necessary for erection.
(3) 
The complete marker shall be four-way and shall consist of two double-face signs mounted on a two-inch galvanized pipe set in a concrete base.
(4) 
The pipe standard shall extend 10 feet out of the ground and at least two feet into the concrete base. The concrete base shall be a minimum of 15 inches in diameter and shall extend a minimum of two feet deep in the ground.
