Stormwater flood modelling data<\/SPAN>.<\/SPAN>Depth values in metres.<\/SPAN><\/P>

RLC data<\/SPAN>: <\/SPAN>This modelling was produced to inform infrastructure planning and is indicative only. It is produced at a catchment rather than property-specific level and incorporates a range of assumptions and limitations. Rotorua Lakes Council and its consultants accept no responsibility for the accuracy of the mapping or any decisions based on it.<\/SPAN>NOTE: Catchments may be part of more than one model - make sure to use appropriate queries on the data. <\/SPAN><\/P>

Catchment-specific comments/assumptions:<\/SPAN><\/P>
