  36. 36. Trees, Urban Environments, and Soil Volumes
  37. 37. Preserve Existing Trees...
  38. 38. Preserve Existing Trees...
  39. 39. “Meeting the Goals of the Miami-Dade County Street Tree Master Plan” •Planning •Planting •Pruning •Education and Growth •Best Management Practices (BMP) ROOT ZONE GROWING AREA “Design the soil space under and adjacent to the hardscape to sustain root growth – good trees well connected to the ground only develop if the roots have room to grow” “Miami-Dade County Street Tree Master Plan” Page 7- March 2007
  40. 40. “The major impediment to establishing trees in paved urban areas is the lack of an adequate volume of soil for tree root growth.” Urban Horticulture Institute December 2000
  41. 41. Trees Growing in Confined Soil Spaces are Prone to Toppling… …Rate of growth is greatly reduced…and… will be short- lived. “Better to plant a 50 cent tree in a 5 dollar hole than a 5 dollar tree in a 50 cent hole”
  42. 42. Make Bigger Planting Spaces. Mi n Ma ax x M Mi n? JAMES URBAN, FASLA, ISA Balance the size of paved and soil areas.
  43. 43. How Much Soil ? Larger Trees 1200 CF Soil Volume = 20’ x 20’ x 3’ depth 20” Trunk Diameter e e siz tre me of u o vol ti l Ra soi to More Soil JAMES URBAN, FASLA, ISA 20” Trunk Diameter Tree will require 20’ x 20’ x 3’ deep soil volume (min.).
  44. 44. Make Space for Roots. JAMES URBAN, FASLA, ISA Design spaces for roots under the pavement and utilize different approaches to root space design as conditions change
  45. 45. Roots grow well beyond canopy edge Dr. Ed Gilman, U of Florida  Trees that normally grow a very expansive root system can become stressed and grow poorly in urban landscapes where soil space is limited  The result can be poor tree health, damaged sidewalks and curbs, and other problems
  46. 46. “Downtown Kendall Urban Center District” “Street Trees: …minimum caliper of six (6) inches and a minimum clear trunk of eight (8) feet at the time of planting.” TYPICAL MINIMUM SIZE OF 18’ OVERALL HEIGHT SITE PLAN PROVIDES STREET TREES BUT… IN 3’ X 3’ SQUARES…(27 C.F. OF SOIL VOLUME )! WILL THESE TREES GROW? HOW LONG WILL THEY LAST? WHERE IS THE 1200 C.F. OF SOIL VOLUME?
  47. 47. “CU-STRUCTURAL SOILS” AND PERMEABLE PAVEMENTS Cornell University 1. INCREASE ROOT ZONE AREA… Use “CU Structural Soils” or “Deeproot Silva Cell” Applications 2. USE PERMEABLE PAVEMENTS…
  48. 48. “CU-STRUCTURAL SOILS”... Cornell University Comprised of two main components: 1. Rigid Stone “lattice” Lattice are load-bearing stones for stability and interconnected voids that allows root penetration, air and water movement. 2. Quantity soil (heavy clay loam or loam) Clay holds most of the water and nutrients. With… Gelscape Hydrogel combines with the mix and works as a non-toxic, non-phytotoxic tackifier.
  50. 50. “CU-Structural Soils” and Permeable Pavements...  Street trees  CU-Structural Soil helps create large enough volumes of soils under constructed pavements.  CU-Structural Soil should have a depth of at least 24”, but it is preferred to have 36”.  Parking Lots and Plazas  Trees planted in Landscape Islands will  benefit from CU-Structural Soils and Permeable Pavements.
  51. 51. “DeepRoot Silva Cell”...
  52. 52. “Deeproot Silva Cells”... Load-bearing structural cells… With frame and deck… JAMES URBAN, FASLA, ISA Backfilled with planting soil…
  53. 53. “Deeproot Silva Cells”... JAMES URBAN, FASLA, ISA
  54. 54. “Deeproot Silva Cells”... www.deeproot.com 1 (800) 458-7668 JAMES URBAN, FASLA, ISA
  55. 55. “Deeproot Silva Cells”... 1. Increased Soil volumes enable large trees to flourish… 3. Healthy trees…increase real estate values… 5. Underground bioretention areas manage stormwater on-site… 7. Large tree canopies reduce urban heat- island effect and improve air quality… 9. Expanded soil-volumes reduce rainfall runoff…
  56. 56. “Deeproot Silva Cells”... JAMES URBAN, FASLA, ISA
  57. 57. Structural Cell Applications JAMES URBAN, FASLA, ISA Trees and Rainwater Harvesting
  58. 58. Permeable Pavements… When integrated with “CU- Structural Soils” or “Deeproot Silva Cells” … “Vegetation is watered, reducing the need for irrigation … Ground water is recharged Water resources are preserved Stormwater runoff is reduced Stormwater runoff quality is improved.” www.CoolCommunities.org
  59. 59. Permeable Pavements… U.S. GREEN BUILDING COUNCIL (USGBC) LEED (Leadership in Energy and Environmental Design) CERTIFIABLE “Pervious pavements can be made of concrete, asphalt, open-celled stones, and gravel, that are mixed in a manner that creates an open cell structure allowing water and air to pass through. For example, porous concrete can pass 3-5 gallons of water per minute, which is far greater than most conceivable rain events and highly effective in controlling storm water drainage. “ www.CoolCommunities.org
  60. 60. Respect the Base of the Tree. Trunk Flare Zone of rapid taper JAMES URBAN, FASLA, ISA Do not pave in the area of the tree’s future trunk flare.
  61. 61. Tree Grates… JAMES URBAN, FASLA, ISA
  62. 62. Tree Grates… Tree grates. Many cities install decorative metal grates around newly planted trees. As the trunk grows, it may end up fighting the encircling obstacle. Though some tree grates are designed so that the innermost section can be removed as the trunk expands, rarely do municipalities remove them promptly enough. The grate girdles the trunk, stopping the flow of water and chemicals between the top and bottom of the tree. If the tree doesn’t die first, it may lift the grate and create a hazard for pedestrians. “New Urban News” February 2005
  63. 63. Landscape code changes are oftentimes tedious and lengthy… Departmental Policy Decisions can bypass this…
  64. 64. INCORPORATE USE OF CULTIVARS Use of tree species developed for urban environments. Marshall Tree Farm Quercus virginiana Quercus virginiana Marshall Tree Farm ‘Cathedral’ Quercus virginiana ‘Highrise’
  65. 65. BIODIVERSITY IN THE URBAN LANDSCAPE  Use and introduction of several native species and use of new unused native species.  A necessity to address tendency to “monoculture” use of only a few tree species.
  66. 66. CONTRACT GROWING… •Opportunity to introduce new native tree species. Trees Inc. Jeremy Chancey
  67. 67. HURRICANE DAMAGE AND RESTORATION… (OR LACK OF IT!) 2004 2005 2007 ! Monarch Lakes Blvd. , Miramar, Fl.
  68. 68. SITE UTILITIES: Important component of any developed site Endless conflicts with Landscape Plantings and Landscape Requirements.
  69. 69. ELECTRICAL AND SITE LIGHTING  Lightpoles  Landscape Islands are for trees  Coordination with Electrical Engineer-  15’ Clearance for all trees  Overhead Power Lines  Screening of Ground- Mounted Equipment
  70. 70. ON-SITE STORMWATER RETENTION AREAS  Dry Retention Areas  Wet Retention Areas
  71. 71. USE OF APPROPRIATE NATIVE PLANTS… FICUS HEDGE / Ficus benjamina COCOPLUM HEDGE / Chrysobalanus icaco  Non-native exotic  Native  Will mature as a 50’ x 50’ tree  15’ at maturity  Grows quickly  Moderate growth rate  Will require frequent topping  Very little trimming required  2-3 times per year  Less need for irrigation,  Photo shows result if topping fertilization, pest control, etc. is not continually done.  Less maintenance intensive  Other native species available
  72. 72. LONG TERM GOALS...  Increase Environmental Awareness  Right Tree-Right Place -Concept and Implementation  Enforcement and installation of Florida No. 1 Plant Material at time of installation  Proper pruning and continual maintenance commitment  Environment – Economics – Esthetics  Preservation and Protection of the Natural Environment (air, water, soil, etc.) for future generations.  Restoration of Recoverable Natural systems  Economic Opportunities and Benefits  Improve the Esthetics and Beautification for the Urban Landscape
