- The development causes minimal impact on stormwater quality, and minimises the generation of stormwater
- Water management devices and techniques are incorporated into landscaping and outdoor areas
- Regular management and maintenance of stormwater devices ensures their ongoing effectiveness
Stormwater runoff from impervious surfaces such as roofs and paved areas can harm the environment and cause damage to private property. Major stormwater issues include flooding, erosion, impacts on water quality and public stormwater infrastructure costs. Rain falling on a development must be either retained on site or conveyed elsewhere – usually through the city’s stormwater network.
The best opportunity to reduce the impact of stormwater on urban infrastructure and the environment occurs on the development site itself. However, to manage a development’s stormwater in optimal ways requires thoughtful incorporation of systems during the early stages of design and site planning.
