Application

Review Key Considerations

  • Consider Stormwater Management Practices where conditions are appropriate

Design

Review the Plant Finder for Parks approved trees and other plants that perform well in the right-of-way. All selections must be made based on specific site considerations

Review design guidance for Tree Bed

  • The trench of connected tree beds should be left uncovered (and, optionally, landscaped) to improve tree root health
  • Where pedestrian access is necessary (areas of high foot traffic, limited sidewalk space, or frequent curbside access), pavement can be bridged over the tree-bed trench using a suspended pavement system to increase soil volume; review Soils
  • Consider the use of permeable pavement such as Permeable Interlocking Concrete Paver (PICP) or Precast Porous Concrete Panel (PPCP) in conjunction with a suspended paving system as long as appropriate maintenance can be provided
