Description: <p><font size="3">This layer represents the results of the VTrans Vulnerability Assessment, which is a screening-level assessment of the vulnerability of Virginia’s transportation system, more specifically all public roadways and VDOT-maintained structures (bridges and culverts) covered in the National Bridge Inventory (NBI), to projected sea level rise, storm surge, and inland/riverine flooding scenarios. The VTrans Vulnerability Assessment is not intended to be used to develop location-specific recommendations for the following reasons:</font><br /></p><ul><li><font size="3">While this screening-level assessment narrows the universe of transportation infrastructure for further review, it does not replace the need for the collection of more precise location-specific data.</font></li><li><font size="3">The transportation system is one of the many infrastructure components impacted by the forecasted vulnerabilities. Therefore, it would be advisable to conduct a more comprehensive area-wide assessment for all components of physical and social infrastructure as some vulnerability mitigation strategies might require systematic solutions such as perimeter protection.</font></li><li><font size="3">As noted in the VTrans Macrotrend 1: <a href="https://vtrans.org/resources/2021_VTrans_Vulnerability%20Assessment_TechMemo.pdf" style="background-color:transparent; color:rgb(7, 80, 128);">Flooding Risk Assessment Technical Memorandum</a>, several critical datasets are either currently incomplete or unavailable. Therefore, our conservative approach capture a few locations that can be deemed as "false positive" as they are either elevated and therefore not at risk from flooding. As mentioned above, this screening-level analysis narrows the universe of facilities at-risk but does not replace the planning or engineering judgment.</font></li></ul><p><font size="3"> Please refer to the <a href="https://vtrans.org/long-term-planning/vulnerability">VTrans Vulnerability Assessment Technical Memorandum</a> for details.<br /></font></p><table border="1"><tbody><tr style="text-align:right; font-weight:bold; color:white; background-color:rgb(1, 70, 122);"><th>Attribute Name</th><th>Alias</th><th>Description</th></tr></tbody><tbody><tr><td>Need_Segment_ID</td><td>Need Segment ID</td><td>This field contains a six-digit unique Identifying number for each directional segment as included in the layer " 2019 VTrans Mid-term Needs (Segments).</td></tr><tr><td>Master_Need_Segment_ID</td><td>Master Segment ID</td><td>This field contains a unique Identifying number that can be used to refer to a particular directional segment.
