My basement flooded during Hurricane Ida. Can I still finish it?

It depends on how the water got in. NK reviews flood history and flood-zone status before design. Groundwater may call for grading, drainage or a sump system. Sewer backup needs a separate assessment; a backwater valve or changes to connected downspouts may be appropriate, but neither is a universal solution. Creek, river or street flooding that rises above openings is different. Finishing below flood levels may be restricted or unwise, so those conditions need review before finish work is priced.
