BEFORE YOU BEGIN!
To find out whether your site is exposed to increasing coastal hazards with sea level rise, you will be redirected to the State of Hawaiʻi Sea Level Rise Viewer.
NOTE: The link to the SLR-XA Viewer will redirect you to another page. DO NOT exit the SLR-XA page (you may need it later), and return here once you are done with the guidance below.
1. Enter your site address on the top-left corner of the Viewer as address number and street name is 9-digit TMK number (click the “i” on the address search tool for help).
2. Return to this page after locating the site of interest.
Note that the SLR-XA maps are a conservative estimate of exposure. If any part of the site is located within the SLR-XA, development could be at risk.
1. Explore the different SLR-XA scenarios (0.5, 1.1, 2.0, and 3.2 ft. of sea level rise) on the legend located on the right side of the Viewer (See screenshot above). Visit “Sea Level Rise Projections for Modeling” below the Viewer window for more information on these scenarios.
NOTE: State and county guidance focuses on the 3.2 ft SLR-XA as the planning scenario for most development.
2. Return to this page after exploring the different SLR-XA scenarios.
Your site is determined to experience direct impacts of sea level rise. See guidance below to find out what types of impacts your site may be vulnerable to and possible actions to take.
1. Return to the Hawaiʻi Sea Level Rise Viewer (the page you were directed to in Step 1).
2. Explore the potential Exposure impacts (Passive Flooding, Annual high Wave Flooding, Coastal Erosion) on your site, located on the right side of the Viewer (see screenshot above).
3. Return to this page after determining potential Exposure impacts on your site, and click on any of the potential impacts below to learn more on what to expect with each risk.
Your site is not expected to be vulnerable to sea level rise impacts. Continue to plan as usual.
