No way will they have a COI for floods. It occurred while Yacoob was holding the position for a long time. You cannot hang out the top Malay PAP politician to dry, there will be a community revolt.
I understand there is second set of foreign consultants looking at it now. It has already gone into the Political space and its on their shoulders. They replaced Yaacob with Viv and with time and if this carries on, Viv would be a good scapegoat. He has already offended half the nation. 2016, another apology and this guy will be next Mah Bow Tan.
