Subsoil Delivery

 

In preparation for the arrival of plants later this fall, a layer of subsoil has just been delivered to the High Line above 19th Street. This soil, part of the High Line's layered Living Roof system, will serve as a base for the topsoil in which plants will eventually grow. Subsoil is coarser and typically contains more clay than the finer, more nutrient-rich topsoil.

Once both layers of soil are in place in the planting beds, they will be covered over to keep them from blowing away before plants are ready.
