We have our ground guy down there at all times moving caution cones and tape. He has a back pack blower as well blowing it back into the planter beds. Now if their is lots of nasty stuff he will pick up the big stuff and bag it. This is for commercial projects. Res. work is more detailed and we bag everything! Clean up very well afterwords. My guys know I or a manager do pop inspections and check the job site when they leave.
