• 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

• Location of swale

• How would you classify this location?
  eg. road reserve, active open space, retarding basin, private property

• Traffic conditions

• This is useful to plan maintenance and repairs
  eg. Low traffic - residential street, high traffic - major road

• 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).

• Evidence of condition

  Media

• Description of condition

• A bioretention swale will have an underdrain as its treatment outlet. A partial observation can be made by checking through an inspection opening (if present) or by looking into pit associated with the swale. Only a limited assessment will be able to be made but try to determine if water is flowing/can flow through it.
  
  If the swale is conveyance only, check N/A and move to the next question.

Hydraulic conductivity

• Is hydraulic conductivity testing required?

  Yes

  No

  N/A

• If condition of surface or vegetation is fair to poor due to too much or too little water for a bioretention swale, the filter media may be compromised. Field testing can give an indication of whether this is part of the problem.

• Rate of hydraulic conductivity (field test)

Asset works priority

• Visibility

  High

  Medium

  Low

  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

  Medium

  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

Final notes

• Based on your observation of the total function of the asset and your individual condition ratings of components, provide an overall rating for the asset. The Condition Assessment Manual contains general guidance.
