Project Construction Methods

Green Street Planter ConstructionGreen street planter construction typically involves the following steps:

  • Saw cut and remove pavement, excavate and place concrete forms for curbs and walls 
  • Pour concrete and let set
  • Remove concrete forms and excavate to final depth
  • Add and level soil
  • Add protective matting, if needed
  • Plant vegetation (spring or fall)

The contractor will use open trench excavation, pipe bursting, jack and bore, and cured in place pipe (CIPP) construction methods to repair, replace, and install sewer pipe for this project. Visit the Construction Methods web page more information about each method and to view photos.
