Nassau Hazard Mitigation Plan

The Nassau County Hazard Mitigation Plan (Plan) emphasizes the County's dedication to identifying and reducing risks associated with natural hazards to increase community resilience. This Plan was developed through a year-long interactive planning process in close coordination with stakeholder groups and iterative input from the public. The process included identifying the hazards of concern within the County, assessing those hazards, estimating risk and potential losses, and developing a strategy with feasible and implementable actions to mitigate risk to these hazards throughout the County.
