            2.2.1     Results
        The Proposed Scenario flood maps are presented in Appendix C: and have been prepared to detail the peak flood depth, velocity and hazard
        in relation to the drainage path influencing the site. The proposed lot layout has been shown within this mapping to highlight how the local
        flooding within the drainage path influences the development. Further discussion is presented below in relation to key components of the
        assessment that relate to:

        •   Flood Depths.

        •   Culvert and Channel Velocity.

        •   Defined Flood Levels and Flood Immunity.

        •   Severe Storm.

        2.2.1.1 Flood Depth and Depth x Velocity (DV)
        An assessment of flood depth and DV in the 1% (2100) AEP highlights that flow depths in the overland flow path are generally less than 0.3m
        and flows depth in the Serentiy Close cul-de-sac head and downstream flood path are generally less than 0.25m and DV less than 0.4m2/s.
        Figure 2.4 details the flood depth and DV in relation to the site in the 1% (2100) AEP. Flood mapping in Appendix C: also highlights that the
        footpath remain dry in the 10% AEP events.
