Right Place (Tree Placement)
Creating tree-lined streets and green pathways can play a lead role in the success and marketability of a new neighborhood. The intentional selection and placement of trees in public spaces will enhance the desirability of the neighborhood by creating a sense of place and attractiveness, increasing safety, and optimizing canopy coverage benefits. A well-designed and maintained plan will help ensure that a neighborhood receives the multiple benefits of a tree lined street like cooler air temperatures, reduced pollution risks, of offering attractive, shaded streets to walk and bicycle down.
Accomplishing this is defined by the term ‘right tree, right place, optimal benefits’, or the practice of proper tree selection and placement. It recognizes that trees are a living part of infrastructure that will grow and change as it gets older and, as such, have additional design considerations to sustain it. This includes looking not only at the space above ground, but also ensuring trees have the right soil conditions and volumes that support trees growing to their potential size. Accounting for these considerations in the beginning of the design process will allow for optimal tree growth to promote the maximum level of benefits to the neighborhood.
The first step of ‘right tree’ was completed when you selected tree species that have the aesthetic attributes you desire for the new neighborhood, and that also met the Green Neighborhood standards for species characteristics. The second step of ‘right place’ is explored in this section and gives you the framework to properly place trees on site plans to optimize growth, survival, and neighborhood benefits, while minimizing risks of tree failure and infrastructure damage.
Goals for Tree Placement
- Trees can reach maturity without interfering with infrastructure, buildings, and other trees.
- Trees have the proper soil volume and conditions to support a healthy, mature, and long-lived tree.
- Trees are placed to maximize the benefits and services they provide.
- Trees are placed to obtain the maximum sustainable tree canopy cover for the neighborhood.
Core Elements of Tree Placement
- A master plan for street and park/greenway trees is included in the initial neighborhood development plan.
- Street trees are placed according to the Green Neighborhood street tree spacing guidelines.
- Residential yard trees are placed according to the Green Neighborhood residential spacing guidelines.
- Street trees have soil volumes consistent with the Green Neighborhood soil volume guidelines.
- Water needs of the landscape are consistent with water needs of the tree, and meets Water Use Classification of Landscape Species requirements.
Elements for Gold
- Planting plan has been reviewed and approved by an arborist or community forester.
- Planting plan developed with SacTree.
