South Complex Burned Area Emergency Response (BAER) Update - September 20, 2015
Release Date: Sep 21, 2015
Contact(s): BAER Information: (415) 881-1871
BAER specialists recently completed their data gathering and verification field work in the South Complex burn areas and finalized a Soil Burn Severity map. Soil Burn Severity grid mapping codes are 1=Unburned/Very Low, 2=Low, 3=Moderate, and 4=High.
The map shows that approximately 78% of the 29,400 acres analyzed by the BAERteam within the fire perimeters of the South Complex are either unburned or have a low soil burn severity, while 19% sustained a moderate soil burn severity and 3% received a high soil burn severity.
The BAER assessment team used the map to model potential impacts to human life, safety, and property from storm events and considered emergency stabilization options for those critical resources.
BAER team leader Brian Anderson stated, "After reviewing conditions on the ground throughout the South Complex burned areas, BAER specialists identified a concern for significant increases in soil erosion and runoff associated with steep slopes and moderate-to-high soil burn conditions. While some these high risk areas exist within the fire areas, the majority of the fires experienced unburned and low burn severity conditions where run-off and erosion is not expected to be measurably changed as a result of the fires."
The soil burn severity BAER map can be downloaded at the “2015 Shasta-Trinity Post-Fire BAER” InciWeb site as a JPEG or PDF version under the “maps” tab.
A "Field Guide for Mapping Post-Fire Soil Burn Severity" can help with interpreting the map and can be found online athttp://www.fs.fed.us/rm/pubs/rmrs_gtr243.pdf.
SPECIAL NOTE: Everyone near and downstream from the South Complex fire areas should remain alert and stay updated on weather conditions that may result in heavy rains over the burn scar. Flash flooding may occur quickly during heavy rain events. Current weather and emergency notifications can be found at the National Weather Service, Eureka Office (http://www.wrh.noaa.gov/eka/) website.
