We love our beaches. We build homes beside them, vacation on them, and spend billions of dollars trying to keep them from disappearing.

It’s a place not unlike New Orleans: a delta shaped by risk, resilience, and the belief that with enough ingenuity, water can be controlled. But as sea levels rise, that centuries-old confidence is beginning to crack.

Public officials, experts and advocates agree the fee is needed to make up a funding gap, but are split on how it should be carried out.
