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 tree pit
-
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 -
Detention depth
-
There may be a measurable detention depth depending to the tree pit design. This will be the distance between the surface of the soil/media around the tree and the top of the pit.
If none, write 'Nil' -

2.0 Surrounds
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). -

Description of condition
-
A tree pit may have a subsurface inlet which cannot be assessed in a purely visual inspection. Treat the pit lid/grate as the formal inlet unless a further inlet (such as a side entry pit) is directly connected with the asset.

Evidence of condition
-
Description of condition
-
The treatment outlet of a tree pit is the underdrain. A partial observation can be made by checking through an inspection opening (if present) or by looking into pit associated with the pit. Only a limited assessment will be able to be made but try to determine if water is flowing/can flow through it.

Description of condition
-
Due to their constrained space, an inspection opening should be present on all tree pits where possible in order to be able to identify blockages quickly.

Description of condition
Hydraulic conductivity
-
Is hydraulic conductivity testing required?
-
If condition of surface or tree is fair to poor due to too much or too little water, 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)
5.0 Rapid Assessment
Asset works priority
-
Visibility
-
Visibility: Examples of high visibility are shopping precincts, landscaped public open space, general high traffic areas.
-
Catchment
-
High catchment priority (if able to be determined) includes catchments that outfall directly to the bays, or are upstream of sensitive areas
-
Treatment
-
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
-
Surrounds: Examples of low priority are assets in disturbed areas such as residential streets with ongoing construction that will stymie maintenance efforts

-
Overall assessment category
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 provides general guidance.
