\"Virginia Coastal Resilience Master Plan (CRMP) Mean High Water Change in the Far Future High planning scenario.<\/SPAN><\/P> Rising sea levels will lead to an increase in the area inundated during high tide. This dataset depicts the geographic extent of tidal inundation during Mean High Water (daily high tide) in the Near Future Moderate planning scenario, relative to baseline conditions. This illustrates how tidal conditions are projected to change over time due to relative sea level rise. The raster data has a 10-foot resolution scale. <\/SPAN><\/P> In the CRMP, planning scenarios are defined by their time horizon and projection range, representing future conditions and the uncertainty inherent in climate forecasts that project them. This dataset contains information for the Far Future time horizon, meaning it is suitable for planning through the next 75 years and is based on climate data most relevant to the period between 2060 and 2100. Within this time horizon, this dataset shows a High climate change projection, indicating a less likely but possible future with higher sea level rise and precipitation estimates, which may be favored for use in decisions with little tolerance for risk.<\/SPAN><\/P> The CRMP\u2019s coastal flood modeling considered changing relative sea level rise projections based on the NOAA 2017 Intermediate High Curve. Complete documentation of the source data and production process can be found in the VA CRMP Phase I Appendix C \u2013 Coastal Flood Hazard Framework Report (Dewberry, 2022).<\/SPAN><\/P> Related resources include the VA CRMP Master Plan report (https://www.dcr.virginia.gov/crmp/) and Coastal Resilience Web Explorer (https://www.dcr.virginia.gov/crmp/cr-web-explorer). <\/SPAN><\/P> For questions or additional information, please contact Flood.Resilience@dcr.virginia.gov.\"<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
