Is it safe to use salt on your parking lot?

 Salt will not harm your asphalt parking lot or driveway.  When it comes to asphalt (not concrete).  But, the run off will affect plants and animals in the area.    More importantly make sure that if chains are used on tires, that they do not allow the wheels to spin in place as they can leave deep gashes in the asphalt that will need to be repaired.  Rubber Chains are an alternative that will do less damage to your asphalt.  It is also a good idea to keep an eye on the snow removal services that are clearing your property to be sure that any heavy machinery that may be using chains are not spinning their wheels in place during the snow removal process.
