An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for water flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly. The projections are deformable under a compressive load and define a first deformation characteristic associated with an athletic response characteristic. The core defines a second deformation characteristic associated with a bodily impact characteristic. Both deformation characteristics are complimentary to provide a turf system bodily impact characteristic and a turf system athletic response characteristic. |
