# Stormwater 1.1 Stormwater Treatment
# Applies to
All development, including residential and non-residential development
# Objective
To minimise negative environmental impacts of stormwater runoff and maximise onsite re-use of stormwater
# Summary
Points are awarded when a STORM rating of at least 100% or equivalent modelling results (e.g. MUSIC *) has been achieved.
*Consult with the relevant council to determine which tool is most appropriate for your development.
# Documentation & evidence required
- Copy of STORM or MUSIC report
- Drawings indicating catchment areas, slope of paved surfaces to treatment systems, construction details of proposed treatment systems, e.g. raingardens
- Landscape drawings indicating appropriate planting within and adjacent to treatment systems
# Other Considerations
Applicants are encouraged to consider additional Stormwater Management strategies not currently included within the tool scoring, for example:
- Installing gross pollutant traps where hardstand paving drains to SW system
- Installing pervious paving where appropriate
- For industrial developments - contain polluting activities within the canopy line or within a bunded area
