Garages, retaining walls and shaded cliffs
Parking garages and ramps collect oil, tire marks and salt carried in on car wheels in winter. Walls under the cliffs and along the steep side streets stay damp and shaded, so algae and moss show up on stone, concrete and block. Plaza paving between towers takes spills, pet waste and fallen leaves.
Wind off the Hudson and the cliffs can carry spray farther than expected, so we choose calmer periods for work on exposed edges. Steep driveways and walkways need non-slip footing for the crew and clear signage for residents. We look at slope, drainage and what happens to water once it leaves the surface.
