Changes to Coastal Development in Qld

    Thursday, June 09, 2016

    On the 3rd of February, the Qld Government’s new Coastal Management District (CMD) came into effect. You may be wondering whether this affects your development… To assist our clients, Burchills has compiled the following summary of the changes.

    What is the Coastal Management District?

    The Coastal Management District (CMD) is generally used to define coastal hazard areas that the State considers require special development controls. Coastal hazard areas consist of areas at risk from either:

    • coastal erosion; or
    • permanent inundation from tidal water; or
    • temporary inundation resulting from a defined storm tide event.

    What are the changes?

    The new CMD mapping is similar to the old mapping but has taken into account an updated shoreline position and the projected sea level rise resulting from climate change - 0.8 metres by 2100. As a result, the new CMD mapping includes a number of additional lots where tidal inundation may occur from sea level rise. The main changes on the Gold Coast occur around the Pimpama Jacobs Well area. The new mapping also acknowledges major tidal control structures on existing waterways and ceases at these tidal controls.

    Why the changes?

    The Qld Government have made these changes to ramp up the planning and assessment process with the desired outcome to enhance the resilience of coastal communities. The Government is concerned that unregulated coastal development can lead to costly and sometimes undesirable property protection works that could damage nearby beaches or cause adverse impacts on the local environment.

    What land is affected?

    The location of the new CMD is shown on the Qld Government’s coastal hazard maps page and on the interactive mapping system on the DILGP website. The new mapping is lot-based and used the digital cadastral database as at July 2015. The CMD mapping generally includes lots where permanent inundation by tidal water or increased coastal erosion from sea level rise is expected to occur. However, only lots close to tidal water (creeks, rivers or the open coast) are included.

    What developments are affected?

    As with the old mapping - development that falls within the CMD is subject to assessment against the provisions of the State Development Assessment Provisions Module 10: Coastal Protection. To ensure the proposed development complies with Module 10 - a Coastal Hazard Assessment is required as part of the development application documentation. Types of development that that are subject to assessment include:

    • Operational works, such as tidal works, interfering with quarry material, disposing of dredge spoil, or constructing an artificial waterway, removing or interfering with coastal dunes
    • Material change of use of premises
    • Reconfiguring a lot
    • Buildings seaward of a coastal building line

    Prior to making a development application, landholders and developers should determine whether their land holdings are affected by the new CMD and if so, what impact it will have on future development or re-development of the land.

    Need any assistance...

    Our Environment and Planning team are experienced in the assessment of coastal hazards and can help determine whether your property is affected by these changes and what documentation is required for a development application. Typical documentation that may be required for developments in coastal and flood prone areas include:

    • Coastal Hazard Assessment - an assessment against SDAP Module 10c
    • Flood Emergency Management Plan - Burchills are one of a handful of firms certified to prepare these reports
    • Stormwater Management Plan
    • Hydraulic Impact Assessment
    • Marine Plant / Seagrass Surveys
    • Hydraulic Impact Assessment
    • Ecological Restoration Plan
