Name: Classified Mean Wildfire Hazard Within Stand

Display Field: OID_COPY

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <p>This is a map of relative wildfire hazard for Marin County. Wildfire hazard is based on a number of inputs: modeled flame length using the 2020 Marin County 5-meter fuel model, extreme fire weather potential, ember load index, suppression difficulty index, human development proximity, transmission line proximity, and historic ignitions. These inputs were assigned weights and summed. The resulting values were published as a 20 meter countywide raster and the mean hazard value was calculated for each fine scale vegetation map stand.</p> <p>See Chapter 8 of the&nbsp;<a href="https://www.onetam.org/sites/default/files/pdfs/marin_regional_forest_health_strategy_2023.pdf">Marin Regional Forest Health Strategy</a>&nbsp;(Page 434 - Calculating Wildfire Hazard Within a Stand) for more information.</p>
