 Noosa Shire Council Coastal Hazard Adaptation Plan: Project Summary                                                       24
 Findings




         Risks to the Teewah township from coastal erosion are covered in section 3.1.

3.4.6    Lake Weyba and Surrounds
         Low density residential properties front the western edge of Lake Weyba, which is otherwise
         surrounded by National Park. The Noosa Aerodrome (a private facility with low use), is also situated
         on the western shore of the lake. Residential properties along Weyba Creek close to the lake are
         subject to both storm tide inundation and permanent sea level rise, with approximately 20 properties
         (including approximately 15 dwellings) ranked as being at Very High risk from sea level rise by 2100.
         Lake Weyba Drive (and critical infrastructure) is also at a High risk from permanent sea level rise,
         with access affected.

         Foreshore parklands around the lake edge, which include sections of Noosa National Park, have a
         high environmental value, are at High risk as a result of permanent sea level rise by 2070, rising to
         a Very High risk by 2100.

3.4.7    Lake Cooribah, Lake Cootharaba and Surrounds
         Lake Cooribah and Cootharaba form part of the Noosa River system and are surrounded by the
         extensive Great Sandy National Park. Adjacent to these features are areas of rural and residential
         property, including a closed settlement on the south-western shore of Lake Cooroibah and a small
         township at Boreen Point. Open space/conservation areas immediately around the lake shores and
         the ecological values these support are at a High risk by 2070 as a result of permanent sea level
         rise and storm tide inundation.

3.4.8    Summary
         Asset risks that were considered High or Very High through the risk assessment (as summarised
         Table 3-1), are considered Intolerable and require further investigation to determine potential risk
         mitigation measures.
