6.0 Rapid Assessment

6.1 Asset works priority

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

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

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

6.2 Initial assessment

Health and safety issues

Are there any elements or issues that the assessors consider to be a risk to health and safety? Please provide a full description

Planned maintenance tasks

Corrective maintenance tasks

Initial outcome
