8.2.27 Wetlands overlay code
Note—Where this code includes performance outcomes or acceptable outcomes that relate to:
- ecological assessments, guidance is provided in the Biodiversity areas planning scheme policy;
- site-based stormwater management plan, guidance is provided in the Infrastructure design planning scheme policy.
188.8.131.52 Assessment criteria
The following table identifies the assessment criteria for assessable development.
Development ensures that a wetland is protected, conserved and enhanced to ensure the long-term ecological functionality and flood storage function.
Development ensures that the development footprint, including any road, and any associated filling or excavation is situated wholly outside the wetland.
Note—Where complying with this acceptable outcome, AO1.2 and AO1.3 do not apply.
Development which does not comply with AO1.1 ensures that the development footprint and filling or excavation is located to conserve the ecological function of the wetland by:
(a) maintaining or reinstating ecological connectivity with any adjacent area of High ecological significance sub-category as identified on the Biodiversity areas overlay map;
(b) minimising edge effects by limiting the edge-to-area ratio of the wetland;
(c) minimising fragmentation, including by infrastructure, such as roads, sewer lines, stormwater management devices;
(d) minimising adverse impacts on water quality.
Development ensures that adverse change to the existing hydrological regime experienced by the wetland is minimised.
Development ensures that an integrated site-based stormwater management system:
(a) minimises change to the natural hydrological regime of the wetland;
(b) provides for maintenance or improvement of water quality in the wetland.
Note—A site-based stormwater management plan and supporting hydraulic and hydrology report prepared in accordance with Chapter 7 of the Infrastructure design planning scheme policy can demonstrate the mitigation of hydrological changes to the wetland.
