Abstract:  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. 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.

Purpose: This project was conducted to assess the vulnerability and risk of wildfire to Caltrans-owned state highways. Data sources were sought across the board to analyze a variety of factors that contribute to wildfire and its spread. Analysis included data sets from CAL FIRE, US Department of Agriculture, US Census Bureau, and Caltrans. The resulting analysis found segments along Caltrans state highways that could benefit from fuel load reduction in order to create defensible space along the rights-of-way.

Process step:
Description: A geospatial risk-based model was constructed by Davey Resource Group, Inc. during Summer/Fall 2019. Datasets were collected and assessed through a variety of sources (listed below). Davey Resource Group, Inc., in conjuction with Caltrans, deliberated each potential data source to determine which pieces of information would be most beneficial to the model. Construction of the risk-based model was intended to identify priority routes or segments along Caltrans operated highways that could benefit from fuel load reductions in order to create defensible space along the rights-of-way. The following data sources were used in the study. All data was converted to 30m raster datasets to complete the analysis. A intra-dataset ranking was constructed for each variable in the model using values ranging from 0-7. A value of zero (0) was indicative of No Data. Lower values were reasoned by carrying less risk. A weighted overlay analysis was implemented to determine risk throughout the state. Data were summarized using a 1/10 mile buffer around all Caltrans operated state highways. Data Category | Data Source | Last Updated Date | Model Weight (scale 0-1) Caltrans | Average Daily Traffic Counts (AADT) | 2018 | 0.07 Caltrans | Functional Highway Class | 2018 | 0.07 Caltrans | Life Line Routes | 2018 | 0.14 Cal Fire | Fire Threat | 2013 | 0.08 Cal Fire | State Responsible Areas (SRA) | 2018 | 0.05 Cal Fire | Fire History | 2018 | 0.05 Cal Fire | Large Trees | 2015 | 0.05 US Census Bureau | Families in Poverty | 5-year American Community Survey 2013-2017 | 0.03 US Census Bureau | People with Disabilities | 5-year American Community Survey 2013-2017 | 0.03 US Census Bureau | People with English Speaking Difficulties | 5-year American Community Survey 2013-2017 | 0.03 US Census Bureau | People Over 65 | 5-year American Community Survey 2013-2017 | 0.03 US Census Bureau | People Under 5 | 5-year American Community Survey 2013-2017 | 0.03 US Census Bureau | Households Without a Car | 5-year American Community Survey 2013-2017 | 0.03 US Census Bureau | Housing Density | 5-year American Community Survey 2013-2017 | 0.04 US Department of Agriculture | Fire Return Interval Departure | 2017 | 0.06 US Department of Agriculture | Wildland Urban Interface (WUI) | 2015 | 0.06 US Department of Agriculture | Surface Waters | 2010 | 0.03 US Department of Agriculture | Wildfire Threat to Water | 2010 | 0.03 US Department of Agriculture | Site Quality/Productivity | 2019 | 0.03 US Department of Agriculture | Standing Timber | 2014 | 0.03 US Department of Agriculture | Carbon Storage | 2013 | 0.03 Each road segment was summarized for its average risk value within the buffered zone. The scores were then normalized by dividing the score by the highest score and multipling by 100. This puts the scale in a easy 0-100 scale, where 100 is the highest priority. The normalized values were statistically binned into seven (7) classes within ArcGIS using Natural Breaks classification. The top 3 classes were deemed as the priority range for this analysis. With the priority segments indentified, additonal GIS analysis was performed to assign each segment a Caltrans District, Cal Fire Unit, California State Park, National Forest, BLM Unit, Tribal Land, and County, if applicable. Data was also processed to include post mile markers for the closes ranges to give a better understanding of the location for each potential fuel reduction project.

Data quality report - Conceptual consistency:
Measure description: Data analysis was conducted on a statewide scale. All efforts were made for spatial datasets to have the same spatial resolution of 30m. Routes were selected based on a weighted model that was constructure using 21 spatial datasets. Routes were not field verified for practitcallity. ANy user of the data would need to conducted their own self-assessment as to the viablility of the priority segment for fuel load reduction.

Data quality report - Temporal consistency:
Measure description: Data for this project spanned from 2013 to 2019. Datasets were vetted for their usage and the ones within this analysis were deemed to be appropriate in the risk assessment. All datasets used were in their most current form. Caltrans and Davey Resource Group, Inc. completed a thorough review of all data prior to analysis and will not be held accountable for any changes or updates made to the data based on any data updates after August 2019.
