I am pulling together a maintenance manual for a design studio that wants to install storm water mitigation in its projects. After reading widely, I have noticed that most information has the same maintenance guidelines. I find it difficult to believe that if sedimentation must be cleaned out 4-5 times a year from an in-street planter in Portland, that the same schedule would apply in Los Angeles. There it seems it should be after major storms or something.
Has anyone out there dealt the REAL maintenance that must happen or know maintenance people I can talk to?
