• Asset function

• Asset Function: (a general description)
  - location
  - catchment
  - key features eg, concrete apron to assist in sediment removal
  - predominant plant species (if present)
  - depth
  - current condition

• Type of catchment

• Type of catchment:
  eg. pavement only, grassed, garden beds, residential, industrial, other

• Previous inspections

Independent structures (part of asset)

• This section is for structures that are included as part of the asset. Many signs, bollards etc will have their own asset ID.
  
  Using the condition assessment manual as a guide, rate the individual component. Take photographs to corroborate the rating, and make note of the material and any other important points in the description, including the number of components (if multiple).

  Media

• Description of condition

• The inlet is likely to be a pipe, and may be partially or fully submerged. Make the most complete observation possible, allowing for the potential for blockages of inlet sections that are underwater.

• Evidence of condition

  Media

• Description of condition

• The outlet of a constructed wetland is likely to include a grated pit structure housing a baffle plate. This may not be directly on the water's edge so look around the perimeter if it isn't immediately clear.

• Evidence of condition

  Media

• Description of condition

• Where a sediment basin and wetland are separate bodies of water, they will be connected by a transfer structure. This could be a porous rock weir, or it could be a concrete pipe linking an outlet pit and inlet. When describing the condition make note of the structure type.

  N/A

• Visibility: Examples of high visibility are shopping precincts, landscaped public open space, general high traffic areas.

• Catchment

  High

  Medium

  Low

  N/A

• High catchment priority (if able to be determined) includes catchments that outfall directly to the bays, or are upstream of sensitive areas

• Treatment

  High

  Medium

  Low

  N/A

• Treatment: High asset priority (if able to be determined) would include an asset that is the lone treatment in a catchment, or performs a significant proportion of treatment within a catchment

• Surrounds

  High

  Low

  N/A

• Surrounds: Examples of low priority are assets in disturbed areas such as residential streets with ongoing construction that will stymie maintenance efforts
