Water resources are protected from the adverse effects of subdivision and development.
Subdivision and development is located and designed to minimise adverse effects on ground and surface water resources, particularly the life-supporting capacity of water bodies and their riparian margins.
Subdivision and development on the margins of natural watercourses and wetlands should be located and designed to maintain, and where possible enhance:
i. Riparian margins.
ii. Water quality.
iii. Water resources.
iv. Aquatic habitats.
Measures to facilitate the efficient use of water resources are incorporated into new subdivision and development.
Water-sensitive techniques are incorporated into new subdivision and development to reduce demand on water supplies, wastewater disposal and to manage stormwater.
Three Waters infrastructure
is provided as part of subdivision and development, and in a way that is:
All subdivision and development provides integrated Three Waters infrastructure and services to a level that is appropriate to their location and intended use.
Subdivision and development shall not occur unless the required infrastructure is available to service it.
Three Waters infrastructure is to be designed and constructed in accordance with any existing Structure Plan and relevant Integrated Catchment Management Plan.
Large scale subdivision and development proposals are to prepare an Integrated Catchment Management Plan (where one does not already exist) or a Water Impact Assessment.
Council maintains a register of all full ICMPs and can advise of any relevant to a particular development proposal and site.
Where there is conflict between a Structure Plan and an ICMP, the latter will prevail.
|In areas where a full Integrated Catchment Management Plan does not exist the following policies also apply:|
Three Waters infrastructure is designed and constructed to:
||Minimise the effects of urban development on downstream receiving waters and groundwater.|
||Ensure that the capacity, efficiency and sustainability of upstream and downstream infrastructure will not be compromised.|
||Facilitate access, maintenance and operational requirements.|
||Cater for the potential effects of climate change.|
||Ensure appropriate standards of public health, safety and amenity.|
||Ensure that surface water runoff is appropriately managed in accordance with the following drainage hierarchy.|
1. Retention for reuse.
2. Soakage techniques.
3. Detention and gradual release to a watercourse.
4. Detention and gradual release to stormwater reticulation.
Stormwater management techniques are designed and constructed to:
||Maintain or improve the quality of stormwater entering the receiving environment.|
||Avoid or mitigate off-site effects from surface water runoff.|
||Sustainably manage the volume and rate of discharge of stormwater to the receiving environment.|
Water supply infrastructure is designed and constructed to meet consumption, hygiene, water-sensitive design and firefighting requirements.
Wastewater is treated and disposed of in a way that minimises effects on public health, the environment, and cultural values.
