Weill Trees in CU Soil

A site on the Sustainable Landscapes Trail

 What Makes it Sustainable?

  • Soil modification (use of CU Soil™) under compacted stone dust promotes root growth.
  • Tree species were selected for low maintenance needs and adaptation to a challenging hot microclimate with no irrigation.
  • The site creates a place for people to gather in shaded conditions

Background and Justification

In 2005 Weill Hall was constructed across from the Biotechnology Building, creating space for a plaza. The design of the plaza called for two rows of trees in a semi-hard stone dust surface. Stone dust is compacted to meet load- bearing specifications. Often when this happens, soil underneath the pavement is too compacted for roots to grow. CU Soil™ was created at Cornell University to allow trees to grow in paved environments with required compaction yet still support healthy root growth.

Goldenrain Trees (Koelreuteria paniculata) and Silver Lindens (Tilia tomentosa) were chosen for this site because of their adaptation to site conditions, drought tolerance, disease resistance and upright form.
