- Summary
- As requested, this memo provides an assessment of the potential effect of the proposed rediversion on shoreline erosion risk around the estuary margin and along the river edge, including Maketu Spit opposite the marae, Beach Road seawall, foreshore of the township, Papahikahawai Island, the margin of the Corbetts land, Ford Island, the new re-diversion channel and lower Kaituna River. The assessment is based on the modelling report recently completed by DHI (DHI, 2014), a field inspection conducted on Thursday 24 April, previous reports and historic information, and previous experience working on the earlier Kaituna River re-diversion proposals in the 1980’s. All depths and elevations discussed in the report are relative to Moturiki Datum (approximate mean sea level) unless otherwise noted.
