Silverdale borders the Western extent of the M.U.L. boundary. Large flood plains exist to the south and west of Silverdale, with southern Silverdale facing possible threats from a smaller flood plain which borders this region. Assessment of areas suitable for development in Silverdale should allow particularly for the southern flood plain area. Flooding occurs reasonably regularly along John’s creek as well as at Small Road bridge and culvert just south of the bridge (Rodney Council, 2010).
