Stone dust, or crushed stone, is a hard packed material made of fine aggregate that allows for easy access by wheelchairs, walkers, strollers, etc. while providing a more aesthetically pleasing surface than asphalt or concrete.  It often has a somewhat loose topping with a texture that “crunches” when you walk on it.  For parks and gardens, this material is often more appropriate than solid hardscaping because it can be detailed to allow water to absorb rather than run off, providing a healthier environment for trees.  At Forsyth Park, the master plan proposes stone dust areas with moveable seating at the large gathering areas under the tree canopy and along the allee on the south end of the park where the Farmers’ Market is located.
