PO9 Development likely to cause drainage or disturbance to acid sulfate soils, prevents the release of contaminants and impacts on fisheries resources and fish habitats. Note: Management of acid sulfate soil is consistent with the current Queensland acid sulfate soil technical manual: Soil management guidelines v4.0, Department of Science, Information Technology, Innovation and the Arts, 2014. No acceptable outcome is prescribed. PO10 Tidal and freshwater inundation and drainage patterns, extent and timing are maintained or restored such that ecological processes continue and associated fish habitat values and condition are maintained. For bridges: AO10.1 Bridges are designed with abutments the highest astronomical tide. AND For water, sewer or stormwater infrastructure: AO10.2 Infrastructure is placed the existing natural substrate surface level, and natural substrate, surface levels and habitat condition and values are reinstated. For any other development, no acceptable outcome is prescribed. PO11 Development: maintains natural processes of erosion and accretion unless there is an immediate and significant threat; and does not result in increased risk of waterway bed or bank scour or erosion or shoreline or foreshore erosion. No acceptable outcome is prescribed. PO12 The development is designed, and constructed to ensure its long-term use and operability will not result in ongoing adverse impacts or new adverse impacts or additional development including: dredging to maintain access trimming of marine plants warning or protective structures. No acceptable outcome is prescribed.
PO24 Maintenance dredging is consistent with an existing development approval for dredging; and within approved profiles for navigational purposes. No acceptable outcome is prescribed. PO25 Disposal of dredge spoil avoids adverse impacts on marine plants. AO25.1 Dredge spoil is not deposited on tidal land. Temporary works PO26 Fish habitats and the fisheries resources they support are restored to pre-existing or improved condition and extent when the temporary works has ceased. No acceptable outcome is prescribed. PO27 Temporary will be in place or are undertaken for a specified period and for the shortest possible time. No acceptable outcome is prescribed. PO28 A temporary structure is in place for a specified period and is designed to be completely removed. No acceptable outcome is prescribed. Restoration PO29 Restoration does not: compromise condition of fish habitats or fisheries productivity; or substitute a particular fish habitat for another type of habitat, for example, creation of mangrove communities from other tidal fish habitats; or substitute a natural fish habitat for artificial fish habitat; or deliver fish habitats that are likely to be regularly disturbed, such as through predictable sediment removal or maintenance dredging; or deliver fish habitats that will predictably be at a high risk of contamination and/or further disturbance. Note: For further guidance refer to Restoration of fish habitats: Fisheries guidelines for marine areas (FHG 002), Department of Primary Industries, 1998. Restoration works authorised through an endorsed restoration plan under the code for self- assessable development MP06 – s, No acceptable outcome is prescribed.
