Summary
Introduction

Reduced assessment for low risk developments

Ensures compliance with state planning policy for water
quality

Integrated with the Flood overlay code

Stormwater drainage requirements now found in
Infrastructure design planning scheme policy
Policy Setting
 Development achieves acceptable levels of stormwater run-off
quality and quantity as part of an integrated stormwater
management framework
 Protect people and property from local stormwater runoff
 Maintains, recreates or minimises the impact to natural
drainage systems and processes
 Enhances environmental values of waterways
 Maintains the integrity of an efficient stormwater infrastructure
network
Policy Setting
 High risk development
 Demonstrate compliance by submission of a site-based stormwater management plan
(SBSMP)
 Low risk development
 Water quality provisions removed
 No requirement for an SBSMP
 Still need to comply with stormwater quantity provisions
 Compliance with single state planning policy with respect to water quality
 Stormwater code has links to the Flood overlay code to address minor and major stormwater
drainage matters
 If a site creates its own localised flooding issues due to stormwater, the Stormwater code
requires the same minimum floor levels as for overland flow in the Flood overlay code
 Erosion and sediment control standards maintained through compliance with the
Infrastructure design planning scheme policy (IDPSP)
