Total Water Level Estimated Mapped (nearest ft.): N/A ft.
Tide Gauge Selection
Choose the nearest tide gauge or the ‘most suitable’ tide gauge based on your own experience and judgement.
Emission Scenario Selection
Choose an emissions scenario based on future fossil fuel use and policy decisions.
High GHG emissions - Corresponds to a future consistent with the strong, continued growth of fossil fuel consumption.
Moderate GHG emissions - Corresponds to a future consistent with current global policies.
Low GHG emissions - Corresponds to a future consistent with the global goal of limiting warming to 2°C above early industrial (1850-1900) levels.
Select Planning Horizon
Choose an appropriate planning horizon relevant to your planning task.
2030 to represent a near-term planning horizon for assets that may be short-lived.
2050 to represent longer-term regional planning horizons (e.g., long-range transportation planning) or the life of a current 30-year mortgage. It is also the currently assessed point to which sea-level rise values are “locked in” regardless of whether emissions increase or decrease.
2100 to represent a planning horizon for long-lived assets that will last for decades or investments that need to be designed to adapt to uncertain long-term projections for sea-level rise.
2150 to represent a planning horizon considering multiple future generations and policy decisions through the early part of the next century.
Sea Level Estimate Selection
Select a sea level rise estimate based on the level of risk tolerance for your planning project.
