Sea levels are projected to rise by an average of 10–12 inches (0.25–0.3 meters) .

The rise expected in the next 30 years is equivalent to the total rise witnessed over the previous 100 years.

Use tools like the NASA Interagency SLR Scenario Tool to obtain data for specific tide gauges, such as the Philadelphia gauge or other local stations.

The Application Guide for the 2022 Technical Report recommends a structured approach for integrating these projections into local planning:

Failure to curb emissions could lead to an additional 1.5 to 5 feet of rise by 2100. Step-by-Step Implementation Framework

Establish the planning horizon (e.g., 2050, 2100) based on the asset's expected lifespan.

Coastal flooding is expected to occur more than 10 times as often as it does today.

Identify the project type, specific area, and functional goals.
