Asset risk

The tools below address flood risk by allowing you to answer two questions:

• Question 1: Exposure -- What is the exposure to coastal flooding of an asset for a specified height and time period?
• Question #2: Asset Height -- What height above ground does an asset need to maintain in order to achieve a specified level of protection against flooding over a given time period?

TODO & Notes

• This entire section needs work to make it more user friendly.
• NOTE: Minimum exceedance in the data is 0.0032, so 0.002 = 500-year flood isn't available as an option.
• Decide how to implement intermediate and/or high sea level rise (SLR) scenarios --
  • Could just show both results,
  • ...or include text that provides guidance on choosing based on the criticality of the asset.
  • Could just be an elevation,
  • ...or it could be a plot of the elevation that maintains the desired level of protection from the present year (2025) to the user-provided end year
• Change vertical scale from exc to annual % (i.e., multiply by 100)
• Change meters to feet NAVD88

Question #1 -- Exposure

• Question: What is the exposure to coastal flooding of an asset for specified height and time period?
  • Context: "Exposure" is the same as "exceedance", which has units of floods per year.
    • An exceedance of 1 means yearly flooding (1 flood/year on average).
    • An exceedance of 0.01 means 1 flood in 100 years.
  • User input: To answer this question, use the range sliders below to specify two things:
    • asset height
    • end year
  • Exposure will apply for the specified end year, which determines the time period (i.e., end year minus ).
  • Asset height (elevation): meters NAVD 88
  • Time period: start year and end year (time span: years)
• Answer:

An asset with an elevation of meters (NAVD 88) will have an exceedance of for the -year period ending .

Question #2 -- Asset Height

• Question #2: What asset height will maintain a specified level of protection against flooding over a given time period?
  • User input: To answer this question, use the range sliders below to specify two things...
    • End year (i.e., the time period starting in )
    • Flood risk (maximum exceedance that will be tolerated)
• Answer:

To maintain an exceedance below floods/year for the -year period ending , an asset must be mounted at an elevation of meters (NAVD 88).
