As a city we are not ready for climate change especially in Manayunk, NoLibs, along the Delaware piers and banks of the Schuylkill.

Making Venice Island into a park wouldn't mitigate flooding very much. It's certainly true to say that soil absorbs water far better than concrete and asphalt can, but floods like the one that happened last year don't happen just because of inadequate stormwater drainage, they happen because of extreme rainfall and are in most cases, unavoidable.
You
could build a berm on Venice Island in an attempt to keep the eventual 100 year flooding at bay, but that would be expensive and may just end up redirecting more water into the canal.
If the residential floors are built above the 100 year floodplain, I see no problem with this development. Would I live there? Maybe, but that's because I don't own a car.
Better stormwater management along the entire Schuylkill would benefit Manayunk in the long term, but until then other than smaller improvements there's really no huge solution.
Philly in general is attempting to move away from a combined sewer-stormwater system, and when they've finished Manayunk will be in better shape for those 100 year floods. Updating the pumps that are in Manayunk would also help things.
Note: I am not a stormwater expert.
