 Findings




         lines for some properties within the declared Erosion Prone Area. However the beach and significant
         portions of the dunal foreshore are at risk from significant erosion in the present day for most areas,
         with the remainder exposed by the year 2040.

         Although there is a low likelihood of an erosion event occurring (i.e. could occur in 1 in 100 years),
         should that erosion event occur, it would potentially impact private properties as early as 2040, with
         a small number of properties (22) at Sunshine Beach have been rated as being at least High risk as
         a result of erosion. By 2070, approximately 72 properties will be at High to Very High risk at Sunshine
         and Sunrise beaches. By 2100, approximately 109 properties will be at High to Very High risk at
         Sunshine and Sunrise Beaches. No private properties south of Sunrise Beach have been assigned
         a High or Very High risk, with the highest being a Medium risk by 2100 for those assets south of
         Peregian Park. Properties at Teewah are not expected to be at High risk from erosion until 2100,
         with approximately 24 lots impacted (approximately 18 full lots).

         Coastal access infrastructure (i.e. foreshore parklands, car parks, beach access stairs/pathways,
         toilet blocks) within Peregian and Sunshine Beaches are assessed as being at High Risk from
         erosion by 2070. This is based on both the loss of community access and facilities as well as the
         potential cost to Council to maintain or replace this infrastructure. Impacts to other critical
         infrastructure such as water and sewage, energy and lighting networks is rated as High to Very High
         at a number of locations, between 2070 and 2100 due to the cost to replace if impacted as well as
         the disruption to the community. Impacts to the Peregian Beach Surf Life Saving Club are also ranked
         as a Very High risk by 2100, based on the potential loss of a community service and the cost to
         repair should erosion cause damage to this facility. Potential impacts to the surrounding Peregian
         Park are also rated as High by 2070 and Very High by 2100 because of the cost to replace existing
         infrastructure should it be damaged from erosion e.g. playground, skate park etc. Similarly, Sunshine
         Beach Surf Life Saving Club and the adjacent park is also rated as being at a Very High risk to
         erosion by 2070.

         As the major east coast access road, any loss of road access along David Low Way is of a significant
         consequence for the community who utilise it to access their properties. Although there is a low
         likelihood of an erosion event occurring, should it occur there is a potential for loss of access near
         Burgess Creek, isolating homes in the Castaways residential area during an erosion event. This risk
         is rated as Very High by 2040.

         The Noosa North Shore campground – a Council-owned asset – is also rated as a High risk by 2070.

         The full risk assessment results for the open coast area is included in Appendix B.

3.4.2    Noosa Heads
         Noosa Heads is the tourism hub of the shire and encompasses Noosa’s most well-known attractions
         including Main Beach, Hastings Street retail centre, a high number of tourist accommodation
         buildings and access to the Noosa National Park. Noosa Heads is subject to potential coastal
         hazards of erosion, storm tide inundation and permanent sea level rise.

         Noosa Heads is a highly modified environment, with the first protective seawall being constructed
         along Main Beach in 1954 and subsequently upgraded on a number of occasions to protect Hastings
         Street properties from erosion. A training wall constructed in the late 1970’s at the mouth of the river
