 SURROUNDS
 Damaged or removed structures                No damage that poses a risk to public safety or
 (e.g. traffic bollards)                      structural integrity
 INLET
                                              Inlet is structurally sound and there is no
 Erosion
                                              evidence of erosion or subsidence/settlement
 Damaged or Removed Structures                No damage that poses a risk to public safety or
 (e.g. pit lids or grates)                    structural integrity

 Sediment, Litter or Debris                   No blockage
