Delegated Report - Code - Planning RAL21 0035 [As Published]

               possible for the future dwelling on the site with residents able to seek refuge in a PMF event within
               future dwellings.
               The applicant has also submitted a Stormwater Management Plan and Engineering plans detailing
               proposed driveway works required to address address the risk of flooding associated with access
               and egree from the site.
               Councils Development Engineer has reviewed the information and provided the following
               comments:
                      Council’s flood mapping indicates that the site will be impacted by flooding (along the
                      watercourse) and indicates that Jirrima Crescent is also impacted by flooding (approximately
                      150m south of the subject site). In order to determine a suitable standard for the internal
                      access it was agreed that the internal access be constructed to the same immunity as Jirrima
                      Crescent. The existing flood model was accessed by Council’s external consultant and the
                      criteria provided to the applicant’s engineer. The submitted SWMP provides comment on the
                      determined immunity and the engineering design for the access driveway has included
                      drainage features for conveyance of water and the required flood immunity. Relevant
                      conditions have been included in the recommendation.
                      The western part of the site is mapped as being affected by the flood hazard overlay. It is
                      noted that the proposed plans indicate a building envelope within Lot 2 that is clear of the
                      flood hazard mapping overlay. It is considered that no further action is required to ensure
                      that development is not located within the flood hazard overlay.
               Biodiversity, Waterways and Wetlands Overlay Code
               The lot includes a mapped waterway that transects the central portion of the site running in a
               northerly direction and has a mapped riparian buffer area with a width of approximately 165m. The
               waterway has historically been dammed with scattered regrowth vegetation consisting
               predominantly of Melaleuca Quinquenervia along the banks of the waterway with a small section
               at the southern end mapped as biodiversity significance.

               The applicant proposes that the full extent of the riparian buffer should not be protected by a
               vegetation covenant due to it not meeting the definition of an ‘ecologically important area’. The
               applicant states the Noosa Plan 2020 Ecological Important Area definition means it is limited to the
               natural waterway, riparian zone and riparian vegetation defining the riparian zone is the land within
               10m of the adjoining waterway. As part of the applicant’s response to Councils information request
               the applicant states:
                      In response to council’s information request, it was proposed that the waterway transecting
                      the site would be rehabilitated 10m either side of the defining bank, which is consistent with
                                                                                                               Page 5 of 13
