Tauranga's new people over property approach to dealing with floods will still cost an additional $30 million over the next three years.
With a quarter of the city's $392 million debt already sunk in stormwater loans, the council has decided to prioritise works on their potential to save lives rather than stop properties from flooding.
The council has been guided by advice that the investment needed to fix the city's flooding problems was "very significant" and difficult to justify in terms of prudent financial management.
A report by stormwater project manager Campbell Larking said the new approach would still help the community be better prepared and recover more quickly from flooding.
The new spending was in addition to the $15.9 million the council already spent operating the city's stormwater system.
