Households face property damage, health hazards, and remediation costs. Consumers lose access to beaches and water-based recreation, reducing tourism spending. Property values in affected areas may decline due to infrastructure concerns and environmental contamination.
Likely triggers government infrastructure investment mandates, stricter environmental regulations, potential rate increases for water services, and accelerated capital expenditure requirements for wastewater treatment plant upgrades. May prompt review of building codes and stormwater management policies.
