Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Through advanced geospatial analysis, Caltrans and Davey Resource Group completed a priority-based risk assessment of Caltrans state highways to model the risk and vulnerability of road segments that fall within Caltrans jurisdiction. Data used in the model varied in their temporal resolution as well as spatial resolution. To normalize the spatial resolution, Davey Resource Group, Inc. converted all data to raster formats and set the resolution at 30m with a projection of NAD 1983 Albers. The data sets were created statewide for this analysis. </SPAN></P><P><SPAN>Each data source utiltized the most current version. US Census data was taken from the 5-year American Community Survey (ACS) estimates ranging from 2013-2017. US Department of Agriculture data ranged from 2015-2018. CAL FIRE datasets were dowloaded from their website with dates spanning from 2013-2019. Caltrans data included current data from 2018-2019. A description of the data sources can be found in the methodology (lineage) section of the metadata. </SPAN></P></DIV></DIV></DIV>
