Description: The layer supports Maryland Department of Natural Resources (MDDNR) leadership and planners as they endeavor to mitigate or prevent the impacts of sea level change resulting from land surface subsidence and rising sea levels. This HVI uses weighted roadway characteristics - evacuation route and functional class - to standardize the impending hazard - projected sea-level rise - along segments of Maryland State Highway Administration (SHA) centerlines for a particular scenario. Methodology:US Army Corps of Engineers (USACE) provide the sea level change (SLC) estimate-1. SLC is localized using water elevations collected from a qualifying-2 National Oceanic and Atmospheric Administration (NOAA) tidal reference station - NOAA observations are transformed from tidal datum to North American Vertical Datum of 1988 (NAVD88). A final correction for glacial isostatic adjustment and land subsidence is applied to create an SLC value for the official project year, 2015.<Year><Tide: SLC Value><Tide: SLC Value>2015; MSL: 0; MHHW: 1.022020; MSL: 0.52; MHHW: 1.542030; MSL: 0.88; MHHW: 1.902040; MSL: 1.31; MHHW: 2.332050; MSL: 1.82; MHHW: 2.84Classified stillwater elevations:0 = less than or equal to one tenth of a foot (<= 0.10')1 = greater than one-tenth foot and less than or equal to a half foot (> 0.10' and <= 0.5')2 = greater than a half foot and less than or equal to on foot (> 0.5' and <= 1')3 = greater than one foot and less than or equal to two foot (> 1' and <= 2')4 = greater than one-tenth inch and less than or equal to six inches (> 2')Hazard Vulnerability Index (HVI):RISK = (Evacuation Route * 0.5 + 1.0) * ((classified stillwater elevation + .01) / 4.0) * (1.0 / Functional Class) * 0.70-1 The SLC rate used in this study was calculated using the USACE High Curve. See http://www.corpsclimate.us/ccaceslcurves.cfmfor more detail.-2 Closest station with historic records of 40 years or greater. An average or qualifying stations was chosen when the nearest station’s records were insufficient. RE SHA CENTERLINES:The 2012 Functional Class linear file was created with the process of dynamic segmentation, using SHA's Routes and HPMS linear event table that contain ROUTEID, beginning and ending mile point fields and the Functional Classification field, "FUNC_CL".Revised HPMS Functional Classification Codes:1 = Interstate2 = Other Freeways and Expressways 3 = Other Principal Arterial 4 = Minor Arterial 5 = Major Collector 6 = Minor Collector 7 = Local
