In order to better ensure the survival of existing trees, the developer should heed the following guidelines: (a) Protect trees with fencing and armoring during the entire construction period. The fence should enclose an area ten feet square with the tree at the center. (b) Avoid excavations beneath the crown of the tree. (c) Avoid compaction of the soil around existing trees due to heavy equipment. Do not pile dirt or other materials beneath the crown of the tree. (d) Keep fires or other sources of extreme heat well clear of existing trees. .(e) Repair damaged roots and branches immediately. Exposed roots should be covered with topsoil. Severed limbs and roots should be painted. Whenever roots are destroyed, a proportional amount of branches must be pruned so the tree doesn't transpire more water than it takes in. Injured trees must be thoroughly watered during the ensuing growing year. (f) All existing trees which will be surrounded by paving should be pruned to prevent dehydration. (g) No paving or other impermeable ground cover should be placed within the dripline of trees to be retained. E-2 Standards for Street and Parking Lot Trees Trees planted in compliance with the requirements of Section 607 should have most or all of the following qualities. The trees recommended in Section E-10 represent the best combinations of these characteristics. (a) Hardiness (1) Resistance to extreme temperatures. (2) Drought resistance. (3) Resistance to storm damage. (4) Resistance to air pollution. (5) Ability to survive physical damage from human activity. (b) Life Cycle (1) Moderate to rapid rate of growth. (2) Long life. (c) Foliage and Branching (1) Tendancy to branch high above the ground. (2) Wide spreading habit. (3) Relatively dense foliage for maximum shading. (d) Maintenance (1) Resistance to pests. (2) Resistance to plant diseases. (3) Little or no pruning requirements: (4) No significant litter problems. E-3 Formula for Calculating 20% Shading of Vehicle Accomodation Areas Following is an elementary formula for determining the number of shade trees required in and around paved parking lots in order to presumptively satisfy the shading requirements of Sec. 607.3. , Q1 Calculate square footage of the vehicle accomr^.odation area: Include parking spaces, driveways, loading areas, sidewalks, and other circulation areas. Do not include building area and any area which will remain completely undeveloped: sq. ft. O2 Multiply: X .20 Q3 Area to be shaded: sq. ft. ****** Add: ® Area shaded by existing trees to be retained in and around the vehicle accommodation area:* sq. ft. CArea shaded by required screening trees, if any:* © Area shaded by required street trees, if any:* O Subtotal: sq. ft. (If line 7 is greater than line 30 ,'then the shading requirement has been met. If not, go on to line 8 .) ® Enter the difference between line 0 and line0: sq. ft. Q Divide line 707 10 Total number of shade trees required within the vehicle accommodation area: trees *Existing trees retained in compliance with Section 15-316 will be credited according to their actual crown radius. Shaded area may be calculated as follows: 3.14 X (crown radius)2 = shaded area Trees planted within the vehicle accommodation area are credited with shading 707 sq. ft. (Based on a crown radius of 15 ft.) New or existing trees on the perimeter of the parking lot are credited for having only half a crown over the vehicle accommodation area (e.g., new perimeter trees will be credited for shading 354 sq. ft.). Generally, all trees planted in compliance with the screening requirements of 607.4 and the street tree requirements of 607 will be considered perimeter trees. When smaller trees such as Dogwoods are planted, the credited shading area will be adjusted downward to 314 sq. ft. for interior trees and 157 sq. ft. for perimeter trees. (Based on a crown radius of 10 ft.) E-4 Typical Parking Lot Planting Islands Scale: 1 " = 40' E-5 Guide for Planting Trees The trees recommended in Section E-10 have minimal maintenance requirements. However, all trees must receive a certain degree of care, especially during and immediately after planting. In order to protect an investment in new trees, the developer and his or her agents should follow these guidelines when planting: (a) The best times for planting are early spring and early fall. Trees planted in the summer run the risk of dehydration. (b) Plant all trees at least three -and -a -half feet from the end of head -in parking spaces in order to prevent damage from car overhangs. (c) Dig the tree pit at least one foot wider than the root ball and at least six inches deeper than the ball's verticle dimension. (d) Especially in areas where construction activity has compacted the soil, the bottom of the pit should be scarified or loosened with a pick ax or shovel. (e) After the -pit is dug, observe sub -surface drainage conditions. Most soils in the Oriental area are poorly drained. Where poor drainage exists, the tree pit should be dug at least an additional twelve inches and the bottom should be filled with coarse gravel. (f) Backfill should include a -proper -mix of soil, peat moss and nutrients. All roots must bp, completely covered. Backfill should be thoroughly watered as it is placed around the roots. (g) Immediately after it is planted, the tree should be supported with stakes and guy wires to firmly hold it in place as its root system begins to develop. Staked trees will become stronger more quickly. Remove stakes and ties after one year. (h) Spread at least three inches of mulch over the entire excavation in order to retain moisture and keep down weeds. An additional three-inch saucer of mulch should be provided to form a basin around the trunk of the tree. This saucer helps catch and retain moisture. (i) The lower trunks of new trees should be wrapped with burlap or paper to prevent evaporation and sun scald. The wrapping should remain on the tree for at least a year. (j) Conscientious post -planting care, especially watering, pruning and fertilizing, is a must for street and parking lot trees. Branches of new trees may be reduced by as much as a third to prevent excessive evaporation. :rees planted center. See ig list E-10(a). i evergreen ng shrubbery 1 4' on center. inting list E-10(e).

E-10 Lists of Recommended Trees and Shrubs The following lists indicate plantings which will meet the screening and shading requirements of 607 of the Land Use Ordinance. The lists are by no means comprehensive and are intended merely to suggest the types of flora which would be appropriate for screening and shading purposes. Plants were selected for inclusion on these lists according to four prin- cipal criteria: general suitability for the piedmont section of North Carolina, ease of maintenance, tolerance of city conditions, and avail- ability from area nurseries. When selecting new plantings for a particular site, a developer should first consider the types of plants which are thriving on or near that site. Accordingly, native North Carolina species should often be favored. However, if an introduced species has proven highly effective for screening or shading in piedmont towns, it too may be a proper selection. Sections E-11 through E-16 contain descriptions of the trees and shrubs listed here. (a) Small Trees for Partial Screening (1) River Birch (2) American Hornbeam (3) Eastern Redbud (4) Flowering Dogwood (5) Washington Hawthorn (6) Russian Olive (7) Mountain Silverbel:l (8) American Holly (9) Golden Rain Tree (10) Crape Myrtle (11) Sourwood (12) Carolina Cherry -Laurel (13) Cal Tery Pear (b) Large Trees for Evergreen Screening (1) Deodar Cedar (2) Southern Magnolia (3) Carolina Hemlock (c) Large Trees for Shadin (1) Norway Maple (7) Sycamore (2) Red Maple (8) Eastern Red Oak (3) Ginkgo (9) Willow Oak (4) Honeylocust (10) Scarlet Oak (5) Sweet Gum (11) Laurel Oak (6) London Plane -Tree (12) Littleleaf Linden (d) Small Shrubs for Evergreen Screening (1) (2) Glossy Abelia Warty Barberry (6) Convexa Japanese Holly (7) india Hawthorn (3) Wintergreen Barberry (8) Azaleas and Rhodadendrons (4) lhiarf Horned Holly (9) Japanese Yew (5) Littleleaf Japanese Holly (e) Large Shrubs for Evergreen Screenin (1) Hedge Bamboo (6) Japanese Privet (2) Thorny Elaengus (7) Fortune Tea Olive (3) Burford Holly (8) Red Photinia (4) Yaupon Holly (9) Lauretinus Viburnum (5) Laurel or Sweet Bay (f) Assorted Shrubs for Broken Screens (1) Japanese Barberry (7) Drooping Leucothoe (2) Fringetree (8) Winter Honeysuckle (3) Border Forsythia (9) Star Magnolia (4) Vernal Witch Hazel (10) Northern Bayberry (5) Common Witch Hazel (11) Judd Viburnum (6) Pfitzer Juniper (12) Doublefile Viburnum E-11 Small Trees for Partial Screening The following trees are recommended for use in all types of screens. Though smaller than the trees listed in planti nglists E-12 and E-13, each of these trees will reach a height of at least 20 feet. Selections marked with an (*) are also recommended as shade trees and may be credited for meeting the 20% shading requirement for paved parking lots. , RIVER BIRCH (Betula nigra) Height: 20-401; Spread: 8 16' The River Birch is a native tree which usually grows along stream banks. In landscape design, it is adaptable to either high or low locations, but still requires a lot of moisture. This tree has an interesting, papery bark anda graceful branching habit. It has no special pest or maintainance problems. *A.hiERIC4N HORNBEAM (Carpinus carolinia) Height: 20-30'; Spread: 15 20' This native tree has a natural yet refined appearance. It is slow growing, but at maturity it serves as an excellent small shade tree. Its fluted, "muscular" trunk is an interesting feature. In the wild, the American Horn- beam is common in moist rich soil, yet, when used in landscape design, it is soil tolerant and does not require an unusual amount of water. It h-as no pests and no special maintainance problems. EASTERN REDBUD (Cercis canadensis) Hei ht• 20-30' Spread• 12 25' This native tree is covered by beautiful pink flowers in the Spring and develops a dense round crown when allowed to grow in direct sunlight. The Redbud has some pests, and its fruit pods may present a litter problem, but it recommends itself for being drought resistant and tolerant of polluted city air. *FLOWERING DOGWOOD (Cornus florida) Heiqht• 15-30'; Spread: 15 20' The Dogwood is a native woodland tree which is very popular for landscape planting. It is considered to be a fairly hardy tree, but, when planted in direct sun, it must be frequently watered. A healthy Dogwood will develop attractive horizontal branches and a bushy crown. Dogwoods look best when planted in groups or when used as an accent in borders. These trees should be guarded against borers and other pests. W,SHINGTON HAWTHORN (Crataequs phaenophvrum) Height: 25 30'; Spread: 25 30' Hawthorns generally require spraying to prevent disease and insect infestation. However, they are an excellent choice for screening because of their extremely dense and thorny branches. They have proven to be excellent as a headlight screen on highway medians and, when planted close together, they form an inpenetrable living fence. They prefer sun and are tolerant of most types of soil. The Washington Hawthorn is generally considered to be the best of the Hawthorns. RUSSIAN OLIVE (Elaegnus augustifolia) Height: 15-20" Spread: 20 30' The Russian Olive can withstand severe exposure and will grow 5-almost any soil. Its toughness and wide spreading habit make it an exceptional screening plant. The foliage is an attractive silver-gray color and its flowers, though inconspicuous, are very fragrant. The Russian Olive is especially notable for its rapid growth. It has no pest problems but it may require periodic trimming of dead twigs. Small trees (cont.) MOUNTAIN SILVERBELL (Halesia monticola) Hei ht: 20-40'; !:,Dread: 201 . Si verbells are attractive multi -stem trees which are native to the sou heastern United States. They are excellent plantings for a natural effect and are best placed where their small flowers and pods will be closely observed. Compared to other trees on this list, its crown is more open and irregular.- The Mountain Silverbell has no pests, no maintainance problems, and no special soil requirements. AMERICAN HOLLY (Ilex opaca) Height: 15-30'; Spread: 10 20' This familiar native tree possesses a pyramidal evergreen crown with abundant red berries in the winter. It grows best in full sun and prefers moist yet well drained soils. If the lower limbs are allowed to grow naturally, they will branch to the ground. Hollies should be protected from high winds. The American Holly is a relatively slow grower. GOLDEN RAIN TREE (Koelreuteria aniculata) Hei ht: 20-30'; S read: 15-20'. This is an extremely hardy tree, tolerant of city conditions, drought resistant, and capable of growth in most kinds of soil. It bears beautiful yellow flowers and interesting seed pods on its rounded crown. The Golden Rain Tree is a rapid grower but is relatively short.lived. CRAPE MYRTLE (Lagerstroemia indica) Height• 15-25'; Spread: 5 15' this popular flowering tree is decorative and interesting in all seasons. How- ever, it should not be expected to stand alone as a screen. It is most effective against an evergreen background. It grows best —in direct sun and may develop mildew problems when planted in shade. Crape Myrtle may be pruned to a desired shape, but when left on its own it will form a densely branching crown. SOURWOOD (0xyndrum arboreum) Height: 20 30'; Spread 10 15' Sou rwoods are haiidscme native trees whim are imost effective in landscape design when planted -in groups. They are easy to transplant and as each tree matures it assumes a slender form with upright branches. Sourwood prefers relatively dry acid soils. Its only special maintainance problems may be infestations of webworms. CAROLINA CHERRY -LAUREL (Prunus caroliniana) Hei ht: 20-30'; Spread: 15-20'. This tree is prized for its dense evergreen foliage. It may be trimmed as a hedge, but also serves as an excellent screen in its natural form. The Che;�ry- Laurel grows rapidly and has no pests. However, it may not be as cold hardy as other trees on this list. *CALLERY PEAR (Pyrus calleryana) Height: 20-401. Spread• 20 30' The Callery Pear has recently gained popularity as a city street tree because it is impervious to air pollution. Furthermore, it will grow in relatively infertile soils. It is a beautiful, upright tree which grows rapidly and is long lived. However, it may be subject to an assortment of pests and diseases. The "Bradford" variety is recommended for its vigorous habit of growth. E-12 Larqe Trees for Evergreen Screening The following trees are ideal for screening large scale areas such as shopping centers and industrial sites. They are also effective in combination with other, smaller screening plants. All three are moderate to fast growers. They are not considered to be shade trees. Deodar Cedar (Cedrrs deodara) Height: 40-150'; Spread• 30'+ The Deodar Cedar is a useful and attractive evergreen. It should be allowed plenty of room in order to assume its beautiful natural form. Its pendulous branches should be allowed to touch the ground. It prefers relatively dry soils, grows rapidly, and is easy to maintain. "True Cedars" such as the Deodar are not native to North America, but they have become quite popular in the South as a landscape tree. Southern Magnolia (,1agnolia grandiflora) Height: 40-60'; Spread• 25'+ Magnolias are striking trees which serve well as screens when their branches are allowed to grow to the ground. Generally, this tree does well in city conditions, but it should be planted in quite rich acidic soils and it requires a lot of moisture. Furthermore, Magnolias require ample space for growth. If planted in full sunlight, they will grow rapidly. Because it drops large waxy leaves, seed pods, and flowers, the Magnolia may present a litter problem. Carolina Hemlock (Tsuga caroliniana) Hei ht:''30-70'; Spread• 20'+ This native of rocky locations 1-n the North Carolina mountains adapts well to city locations. It may be sheared or pruned to any shape, but when it grows naturally, its graceful branches form an excellent high screen. The Hemlock prefers cooler, partially shaded locations and does best in highly fertile soils. It grows quite rapidly. E-13 Large Trees for Shading The folowing trees may be used for screening, but they are recommended especially for shading streets and parking lots. Unless otherwise noted, they will grow rapidly. Each species will attain a mature spread of at least thirty feet. NORWAY MAPLE (Acer platanoides) Height: 40-50'; Spread: 50'+ Maples as a group are not particularly tolerant of city conditions. The Norway Maple is an exception, however, as it is relatively invulnerable to air pollution and has no special maintainance requirements. This tree assumes a wide spreading form and provides very dense shade. In the autumn, the leaves are a brilliant red or yellow. The Norway.Maple grows rapidly, but it is subject to ice and wind damage. Plenty of room should be available for its shallow roots and it should be given ample water. RED MAPLE (Acer rubrum) Height: 40-50'; Spread: 25'+ This tree is an example of a Maple which is not recommended where there will be high concentrations of air pollution. However, with its excellent shading characteristics and beautiful colors, it should not be ignored. This tree grows rapidly, but, unlike the Norway Maple, it does not become brittle with age. The Red Maple is a native tree which is usually found in moist, even swampy areas, but it adapts well to a variety of situations. Although subject to Maple insects and diseases, it is usually a long lived tree. GINKGO or MAIDENHAIR TREE (Ginkgo biloba) Height: 40-80'; Spread: 30'+ The Ginkgo is a tree which is recommended for several outstanding reasons. It is one of the oldest surviving species of,trees. It is adaptable to any soil, climate, or degree of exposure to the sun. It does quite well in the city. It has no pests, no diseases, and no pruning requirements. In sum, it is a tree of exceptional vitality. The N.C. Department of Forest Resources calls the Ginkgo, "probably the best all around street tree." Two reservations are worth stating, however. First, only male trees should be planted because female Ginkgos bear a messy, malodorous fruit. Second, the Ginkgo is a slow grower. When young, it has a rather gangly appearance. It takes 25 to 30 years to assume its mature, symetrically spreading form. HONEYLOCUST (Gleditisia triacanthos) Height: 50-75'; Spread: 25'+ Its open, spreading form and feathery leaves may give the Honeylocust—a frail appearance, but it is in fact a quite sturdy tree, notable for its resistance to storm damage. It is a native tree which is drought resistant and adaptable to city conditions. Grass and shrubs thrive beneath a Honeylocust because it casts light shade. This tree is especially useful for its ability to be trans- planted at a relatively advanced age. Accordingly, it may be used for immediate effect in a landscape design. The Honeylocust has its pests and diseases, but it is fairly hardy. Thornless and fruitless varieties such as "Moraine" are recommended. SWEET GUM (Liquidamber styraciflua) Height: 60-1001; Spread: 501+ The Seet Gum is a native bottomland tree which adapts to a variety of soils. Its dense foliage and balanced form make it an excellent shade tree for large open areas. The Sweet Gum needs sun and plenty of room to achieve maximum size and beauty. In the fall, its leaves turn a brilliant wine and gold color. Other than clean up of its prickly seed balls, the Sweet Gum poses no special maintainance problems. Large trees (cont.) LONDON PLANE -TREE (Platanus aaerifolia) Height: 70-100'; Spread: 301+ The London Plane -Tree is excellent for streets and parking lots for a variety of reasons. It puts out its branches high enoungh above the ground so as not to obstruct traffic. Its broadly spreading crown makes it especially useful along wide streets. The London Plane is one of the world's hardiest trees in polluted air. Although it needs plenty of sun and moisture, it is undemanding about soil. Finally, it is very long lived. The London Plane -Tree is a hybrid of the Sycamore, and like the Sycamore, it may suffer from certain diseases. However, it is more resistant to leaf 'blight than the Sycamore. SYCAMORE (Platanus occidentalis) Height: 70-1001; Spread: 601+ The Sycamore is probably the fastest growing shade tree on this list. Within ten years, it can grow to a height of between thirty and forty feet. It is easily transplanted, but it needs plenty of space. As one of nature's most massive trees, Sycamores have been known to grow to a height of 170 feet with a trunk 10 feet across. The Sycamore is a native tree which typically grows in flood plains, but it thrives in a variety of situations. Its tolerance of severe conditions has long made it a favorite choice as a street tree. Sycamores are susceptable to fungi and leaf blight and their large leaves and seed balls may present a litter problem. EASTERN RED OAK (Quercus rubra) Height: This tree grows faster than any other Oa prized as a street tree because its high The Red Oak grows in almost any average problems. 50-70'; Spread: 40'+. K, two feet or more per year. It is branching habit gives it an ideal shape. soil and `presents no special maintainance WILLO'! OAK (Quercus phellos) Height: 60-801; Spread• 30'+ This is another rapidly growing Oak. It has proven to be quite successful as a street and parking lot tree in the Carrboro area. Its slender leaves give it a finer texture than that of other Oaks, but it still casts excellent shade. The Willow Oak is native to bottomland soils, and thus it needs plenty of moisture. It often spreads majestically as it matures so it should be given ample room to grow. No significant pests or diseases afflict the Willow Oak. SCARLET OAK (Quercus coccinea) Height: 60-80'; Sp read: 40'+ This is a third Oak which grows rapidly and is easy to maintain. The Scarlet Oak is more difficult to transplant than the Red or the Willow, but it may be a worth- while selection for its excellent foliage. LAUREL OAK (Quercus laurifolia) Height: 40-60'; Spread: 30'+ The Laurel Oak grows more slowly than the other Oaks listed above, but it has the advantage of being nearly evergreen in piedmont sections of North Carolina. It has proven to be a good street tree and does quite well under city conditions. It presents no special maintainance problems. LITTLELEAF LINDEN (Tilia cordata) Height: 30-50'; Spread: 251+ Lindens are notable for their exceptional symmetry and their ability to grow in poor soils. The Littleleaf Linden requires plenty of moisture, but it has proven to be useful for city planting and is especially recommended as a street tree. With its many thick branches and abundant foliage, the Linden provides very dense shade. It should be sprayed for aphids in order to prevent sticky droppings from the leaves. E-14 Small Shrubs for Evergreen Screening The following shrubs are recommended for informal (unclipped) hedges or screens. E species grows to a height of less than six feet; therefore, these shrubs are appropriate for Semi -opaque Screens. GLOSSY ABELIA (Abelia grandiflora) Height: 4-6'; Spread: 3-5 " Abelia is quite common in local nurseries and tends to be less expensive than other shrubs on this list. It bears pale pink flowers throughout the summer. Although it has proven quite popular for informal hedges, it has several draw- backs. Abelia should be pruned and thinned to maintain its best form. It may drop its leaves due to low temperatures, lack of pruning, or starvation. WARTY BARBERRY (Berberis verruculosa) Height: 3-4'; Spread: 3-4' Barberrys as a group have proven to be excellent as hedge plants. With their dense, spiny limbs, they are effective barriers in public places. The Warty Barberry is a shrub with a neat, compact habit. It is soil tolerant and has no special maintainanc requirements. It grows slowly, but it will reach a height of 3 to 4 feet within five years. 14INTERGREEN BARBERRY (Berberis julianae) Height: 4-6'; Spread: 2-5' This is another Barberry which forms an impenetrable thorny hedge. In fact, it grows even more densely than the Warty Barberry. It is pest resistant and is very hardy. No pruning is required. Because it is fairly slow growing, it will take eight to ten years to reach a height of 5 to 6 feet. DWARF HORNED HOLLY (Ilex cornuta:'rotunda') Height: 3'; Spread: 3-4' This shrub is an exce lent selection for a low hedge. It is soil tolerant and requires no pruning or other special care once established. With its spiny leaves, this plant appears to be and is in fact rugged. Like all Hollies, it grows best in full sun, but unlike others of its species, it produces bright red berries without both sexes being present. LITTLELEAF JAPANESE HOLLY (Ilex crenata 'microph lla') Height: 4-6'; Spread: 5 7' This Holly is a good substitute for the more finicky and often more expensive Boxwood. It withstands pruning, but is quite attractive in its natural form. Although considered to be slow growing, it will form a stiff 6-feet-tall hedge within ten years. The Littleleaf Japanese Holly grows well in both sun and shade and does well in city conditions. CONVEXA JAPANESE HOLLY (Ilex crenata 'convexa') Height: 4-6'; Spread: 3 5' The Convexa Japanese Holly is another good Boxwood substitute. This shrub is considered to be one of the most attractive, hardy and servicable Hollies for landscape use. It is attractive in either a clipped or unclipped form. It grows faster than the Littleleaf Japanese Holly.' INDIA HAWTHORN (Raphiolepis indica) Height: 3-4'; Spread: 4-5' With its spreading, irregular branching, the India Hawthorn makes an excellent informal hedge. It is tolerant of a variety of soils and is fairly drought resistant. However, it may not be as cold tolerant and pest resistant as other shrubs on this list. Small shrubs (cont.) AZALEAS and RHODADENDRONS (Rhodadendron species) Hei ht: 3'+; Spread: 3'+. Many varieties of Azaleas and Rhodadendrons are dense and evergreen and are, therefore, good screening material. The universal popularity of this large shrub family belies the fact that its members must not be planted indiscriminately. As a group, Rhodadendron species prefer cool, moist, well drained, acidic soil which has a fairly high organic content. They do best in shade or partial shade particularly when they are planted in extremely hot or windy locations. If planted in full sun, they should receive plenty of water. In spite of these requirements, once established in good soil with the correct culture and water, both Rhodadendrons and Azaleas tend to take care of themselves. Some relatively hardy and vigorous species are: Kurume Azaleas (R. obtusum), Snow Azaleas (R. mucronatum), Indian Azaleas (R. indicum), and the native Carolina Rhoda- dendron (R. carolinianum). JAPANESE YE14 (Taxus cuspidata) Height• 4-61, Spread• 5 7' The versatile Yew is commonly available from local nurseries in a wide variety of sizes and shapes. The Japanese Yew serves as excellent screening material in either a clipped or unclipped form. It tolerates poor growing conditions and flourishes in almost any kind of soil. (Soggy soil may hamper its growth, however.) It is comparatively pest free and is hardy under trying winter conditions. The Yew's best feature is its rich shiny green needles which grow densely on all varieties. E-15 Large Shrubs for Evergreen Screening The following shrubs are recommended for high hedges or screens. Each species grows to a height of more than 6 feet; therefore, these shrubs are appropriate for Opaque Screens. HEDGE BAMBOO (Bambusa multiplex) Hei ht• 10-12'; Spread: 4 6" Hedge Bamboo grows rapidly yet is more easily confined to a limited area than most types of Bamboo. It is adaptable to a variety of situations, but requires plenty of water. For best effect as a screen, Hedge Bamboo should be stagger planted. THORNY ELAENGUS (Elaengus oungens) Height: 8-101; Spread: 6 10' This shrub is tolerant of many adverse conditions. It will grow rapidly in relatively infertile, dry soils. Its dense thorny branches form an excellent natural hedge. It is one of the most common evergreen shrubs in the south. BURFORD HOLLY (Ilex cornuta 'Burfordii') Height: 8-15; Spread: 6 8' The Burford Holly has been called, "one of the best and most servicable of all broad leaved evergreens for general planting in the South." It is soil tolerant, grows rapidly, requires no pruning, and usually has no pest problems. Its dark green leaves lack the usual Holly spines. YAUPON HOLLY (Ilex vomitoria) Height: 5-15'; Spread: 6-12' This is another versatile Holly, slower growing than the Burford, but equally as adaptable to adverse conditions. It is a native shrub which has proven to be one of the most drought resistant of all Hollies. IF may be clipped to maintain any desired height. The Yaupon Holly"is very heavily fruited and will attract birds. LAUREL or SWEET BAY (Lauris nobilis) Height: 10-12', Spread: 8 10' Laurel is -a tough low maintainance shrub which does best in fertile, well drained soils. Pruning is not required but it may be sheared to any desired form. It screens well with a single row planting. The Laurel has'been a popular landscaping plant since ancient times. JAPANESE PRIVET (Li ustrum japonicum) Height: 6-10'; Spread: 5 6' The Japanese Privet will survive almost any adversity including heat, cold, drought, air pollution, and poor soil. Accordingly, it is one of the most popular hedge plants in America. This and other Ligustrums are fast growing and remarkably pest free. They are ideal as a high screen in large scale areas. It has been said that if a Ligustrum will not grow in a particular location, then nothing will. FORTUNE TEA OLIVE (Osmanthus fortunei) Height: 9-12'; Spread: 5 7' This Osmanthus hybrid is a -popular, though non-descript, shrub. With its vigorous growth, it will form an excellent screen or border. It is soil tolerant. The Fortune Tea Olive is most notable for its inconspicuous yet highly fragrant flowers. RED PHOTINIA (Photinia glabra) Height: 6-10'; Spread• 4-5' This low maintainance shrub is often selected for its glossy saw toothed leaves which are a bright red when they first appear. Photinia forms a good hedge when planted in full sun. It has somewhat looser foliage than other plants on this list. In recent years, Red Photinia has become very popular in the Southeast. Large shrubs (cont.) LAURESTINUS VIBURNUM (Viburnum tinus) Hei ht: 10-12", Spread: 10-121. This Viburnum is prized for its luxurient dark green foliage. It is va uable for screens and, though sometimes clipped as a formal hedge, it can remain uncut for years and still keep its good form. It grows best in medium fertile soils and prefers dry conditions in.the late summer. All Viburnums withstand city conditions well. E-16 Assorted Shrubs for Broken Screens The following is a sampling of shrubbery which would be appropriate in a Broken Screen. Because many of these plants are deciduous, they are not suitable for Opaque and Semi -Opaque Screens. (Note: Many of the evergreen shrubs described in plantingl ists E-14 and E-15, are also suitable for Broken Screens.), JAPANESE BARBERRY. (Berberis thunber ii) Height: 3-5'; Spread: 3 5' This extremely common deciduous shrub is considered to be one of the toughest members of the Barberry family. It survives drought, poor soils, exposure, and the worst city conditions. With its many thorns, the Japanese Barberry is often used as an impenetrable barrier, but it is attractive enough to stand alone as a specimen plant. It requires no special maintainance and, when planted singly, needs no pruning. FRINGETREE (Chioanthus virginicus) Height: 10-30'; Spread: 8 10' The Fringetree is known for its profusion of beautiful flowers. It is considered to be one of the most striking native American shrubs. It is relatively difficult to transplant, but once established it does well in cities as it endures heavy smoke and dust. The mature Fringetree's only drawback is that its leaves appear rather late in the Spring. BORDER FORSYTHIA (Forsythia intermedia) Height: 8-10'; Spread: 7 10' Forsythias are well known shrubs which bloom bright yellow quite early in the Spring. There are two commonly available forms of this shrub: the weeping Forsythia suspensa and the more upright Forsythia intermedia. The latter is preferred for screening purposes. With its graceful branches, the Border Forsythia presents a good deciduous foliage mass and should be given plenty of room to grow. It transplants easily and withstands poor growing conditions. It should be thinned occasionally to ensure vigorous growth. VERNAL 14ITCH HAZEL (Hamamelis vernalis) Height: 4-6'; Spread: 2-3' This rapidly growing native shrub is excellent for bordering and naturalizing. It assumes a dense, upright form, thriving in even the most polluted air. Other than plenty of watering, the Vernal Witch Hazel requires no special maintainance. CONiON WITCH HAZEL (Hamamelis vir iniana) Height: 8-15'; Spread: 7 14' This shrub is a larger version of Vernal Witch Hazel with many of the same qualities. It is another native woodland plant which has adapted well to landscaping uses. The Common Witch Hazel is recommended for shady areas, but when planted in the sun it grows to be a splendid well rounded specimen. It is especially useful in large areas. PFITZER JUNIPER (Juniperus chinensis 'Pfitzeriana') Height: 4 6'; Spread: 6 9' This evergreen is recommended for Broken Screens rather than full fledged hedges because its form lends itself to massing rather than row planting. Pfitzer Juniper has been know to grow 6 feet high and spread 10 to 15 feet within ten years. Thus it should be given plenty of room to grow. Despite its exotic appearance, it is a commonly used landscape plant. Junipers, as a group, withstand hot, poor, dry soils of city areas probably better than any other evergreens. However, they do suffer from certain pest problems and should therefore be watched closely once they are planted. Assorted shrubs (cont.) DROOPING LEUCOTHOE (Leucothoe fontanesiana) Height: 3-4'; Spread: 4-61 . Drooping Leucothoe is a moundlike shrub which is good for planting in front of and between other flora and beneath trees. It is hardy in city conditions and gives a natural effect when planted along borders. This native evergreen is graceful and attractive in all seasons. It is easy to transplant but requires a heavy mulch and should be provided with at least partial shade. Old branches should be pruned occasionally to stimulate new growth. WINTER HONEYSUCKLE (Lonicera fraqrantissima) Hei ht 6-8'; Spread: 6-8' The only resemblance between this shrub and the more familiar Honeysuckle vine is its extremely fragrant flowers. The Winter Honeysuckle has leathery semi -evergreen leaves and assumes a globe shape as it rapidly grows. It is a tough plant, soil tolerant and virtually maintainance free. STAR MAGNOLIA (Magnolia stellata) Height; 10-121; Spread: 8 10' This handsome specimen shrub is considered to be the hardiest of all the Magnolias. It forms a broad, rounded mass. It becomes tree -like with age but continues to branch to the ground. Early in the spring, it produces numerous fragrant white flowers. The Star Magnolia should not be planted adjacent to shallow rooting trees. It should be allowed plenty of sun. NORTHERN BAYBERRY (M rica pens lvanica) Height: 3 6'; Spread: 3 8' This shrub, often used for windbreaks at the beach, is also effective for shrub masses in Piedmont areas. Its ability to tolerate salt and sand translates into a quality for withstanding the rigors of city life. Bayberry normally forms a dense, spreading mound. While it is evergreen at the shore, it may annually drop its leaves in less temperate climates. JUDD VIBURNUM (Viburnum juddii) Height: 8'; Spread: 6' Viburnums are sturdy shrubs which are commonly available in area nurseries. The Judd Viburnum is rounded and dense. It bears loose clusters of fragrant white flowers in the early Spring. If given plenty of water, it will grow rapidly. Its fall fruit is attractive to birds. DOUBLEFILE VIBURNUM (Viburnum plicatum tomentosum) Height: 8-101; Spread: 8 10' The Doublefile Viburnum grows larger than the Judd and is noted for its strong horizontal branching habit. It is a very servicable accent plant in shrub borders. The Doublefile Viburnum should be carefully watered in periods of extended drought. ppendix F-2 Computational Work Sheet to.Hand-Calculate Legfrom Sound Level Meter Measurements Recorded on Data Lon A B Noise Level Relative Relative Total Band, dB Count Noise Energy Noise Enera,y 100 98 x 79,400 = 96 x 50,100 - 94 x 31 600 - 92 x 20,000 = 90 x 12,600 = 89 x 8b x 5,010_ 84 x 3,160 _ 8V x 2,000 80 x 1,260 = 7 x 794 - 76 x 501 - 74 x 316 - 7? x 70- x 126 = 6i; x 79.4 - 66 x 50.1 = f 64 x 31.6 = —� 62 x 20.0 = 60 x 12.6 = 58 x 7.94 = 56 x 5.01 = 54 x 3.16 7-- 52 50 x x 2.00 = 1.26 = 48 x .79 = 46 x .501 = 44 x .316 = 4z x .200 = 40r x .26 = 38 x .0294 = 3b x .0501 - 34 x .0316 = -- 3 x .0200 = 3 x .0126 SUM B = _ cl im rV-,i Y,,A r. - SUM D = . . --- —.... - DATA REQUIREMENTS: o Each noise reading must be taken at a standard time interval between measurements. o Each noise level recorded is the instantanteous level.
