What is a Water Sensitive Urban Design Assessments?
Water Sensitive Urban Design Assessments will consider how stormwater runoff will be managed within a proposed development. Whenever a residential or commercial development is proposed, there is a significant amount of hardstand (roofs, concrete driveways etc) proposed. During a storm event, rainwater is then directed into the stormwater system and will have a negative effect on the local environment as well as contribute to flooding of the local area.
A Water Sensitive Urban Design Assessment aims to assess the impact of the additional hardstand areas and incorporate measures such as rainwater tanks and rain gardens to ensure the stormwater is managed appropriately.

Why does getting a good quality Water Sensitive Urban Design Assessments matter
Ensuring the correct treatment features are incorporated into the design is critical to not only preserving the local environment but also ensuring that local flooding (onsite and offsite) is managed.
A low quality assessment may lead to treatments measures that are ineffective and result in wasted upfront capital as well as ongoing maintenance/remedial costs.
