 by the Shire’s coastal location, development pressures, and the extent of exposure to vulnerable communities.

 Flooding and storm­tide inundation are perhaps the more serious threats to Noosa Shire in terms of risks to people and property.
 Potential flooding and inundation from catchment rainfall and storm surge affects large areas of the Shire. The extent and severity of
 flooding and inundation is likely to increase over time as a result of sea levels rising and more extreme weather with a changing climate.
 Development is to be compatible with the flood and storm­tide hazard and is required to be designed and sited to not place people,
 property and natural ecosystems at risk. Areas of flooding and inundation are identified on the Flood Hazard Overlay Maps in Schedule 2.

 Some existing communities in low lying areas that enjoy close connection to the river, natural waterways and the ocean are likely to
 become more vulnerable to severe weather events and the impacts of increasing mean sea levels. Flood immunity and the standards of
 service for drainage in these locations are likely to reduce over time. This includes parts of Noosa Heads, Noosaville and Tewantin.
 Adopting resilient building design as part of developments, including for building upgrades and extensions, will improve flood resilience.
 This also includes adopting minimum floor heights, using materials with high water resistance and elevating electrical systems and
 power outlets to above flood levels.

 Council is conscious of environmental risks associated with undertaking development of marine infrastructure in coastal and riverine
 locations and as such there are no prospects or support for additional canals, dry land marinas or other forms of artificial waterways in
 Noosa Shire.

 Coastal erosion affects large sections of Noosa's beaches from Peregian Beach to Noosa North Shore, including Noosa Main Beach
 and the lower Noosa River estuary foreshores. The effects of more frequent extreme weather and sea level rise are projected to
 exacerbate erosion risks. It is important that the natural buffering capacity of the coastal environment and natural coastal processes are
 maintained or enhanced. Coastal values are required to be protected from building encroachment and uncontrolled public access into
 coastal beachfront areas. Private access over foreshore land or beachfront reserves by individual property owners is discouraged and
 not permitted. Erosion prone areas and coastal building lines are shown on Coastal Protection and Scenic Amenity Overlay Maps in
 Schedule 2.

 Steeply sloping and erodible lands of certain soil types have landslide potential across large areas of the Shire presenting risks to
 people and property and requiring careful measures through geotechnical investigations and design to ensure the long term stability of
 development sites and structures. Areas subject to potential landslide hazard are shown on the Landslide Hazard Overlay Maps in
 Schedule 2.

 Bushfire hazard affects large areas of Noosa Shire due to local climate conditions, extensive vegetation cover and variable terrain.
 Increased temperatures due to climate change will increase the likelihood, intensity and extent of areas affected by bushfires and
 lengthen fire seasons. Development is avoided in bushfire hazard areas or where development cannot be avoided, risks are mitigated to
 an acceptable or tolerable level through location, design and materials. Areas subject to potential bushfire hazard are shown on the
 Bushfire Hazard Overlay Maps in Schedule 2.

 Low lying areas across Noosa Shire contain acid sulfate soils that, if exposed, can result in damage to buildings, assets, infrastructure
 and the local environment. The disturbance of acid sulfate soils is be avoided where possible. Where disturbance is unavoidable, the
 disturbance should be minimised or managed to prevent the mobilisation and release of acid, iron and other contaminants. Areas
 subject to potential acid sulfate soils are shown on the Acid Sulfate Soils Overlay Maps in Schedule 2.

 With the projected increase in mean temperatures and heatwaves as a result of a changing climate, public places require shade (both
 natural and built) to help reduce direct sun exposure and the incidence of melanoma. This includes footpaths, public facilities, dining
 areas, parks, communal areas and car parking areas.

 Noosa Shire contains hazardous abandoned mines relating to former mining activity, including disused underground mines, tunnels
 and shafts. Information on abandoned mines can be obtained by visiting the Queensland Government website for more information
 www.qld.gov.au/environment/land/abandoned­mines/ and additional information on historic mining activities can be gained from
 GeoResGlobe on the Business Queensland web site.

 Note: This mapping does not spatially represent all former mining activities in the Council area, and their extent. However, these mining
 layers do give an indication of where there is an increased risk of hazards from former mining activities so that further geotechnical
 investigations can be undertaken where necessary.
