Officials with the National Weather Service released their monsoon prediction on May 4, and the prediction calls for a normal or above-normal monsoon season. "The danger associated with monsoon storms really depends on the storm and the year." "Monsoon season is always unpredictable," said Lacroix. Tonto National Forest Hydrologist Kelly Mott Lacroix said she has similar concerns about monsoon threats every year. Meanwhile, the additional damage will present possible threats to downstream communities as monsoon season creeps in. Officials say some areas are considered re-burned, as parts of the land burned by this wildfire contain burn scars from the Schultz Fire in 2010. "I don't want to say it resets the flood risk, because the initial burn scar, it burned all the way to the top of the mountain and really steep topography with really steep canyons, and the soil burn severity on that was a lot higher," said Waterman. Meanwhile, almost 1,500 acres of land sustained moderate burn, and approximately 11 acres are classified as high burn areas. it's the areas with moderate and high."Īlmost 5,000 acres are considered unburned, while 13,000 acres are identified as low-burn. The big triggers for accelerated erosion and increased run off. "I think fire-wide, we're looking at 92% of the fire was either unburned or low soil burned severity. "Our observed soil burn severity, it's on the lower end of things," said Brendan Waterman, the BAER team lead for the Tunnel Fire. Officials with the BAER team assembled for this wildfire say since April 30, they have been assessing damage to the soil, utilizing satellite imagery to look at the soil and vegetation damage. The Burned Area Emergency Response Team (BAER) has been surveying the damage caused by the fire, and what it means as monsoon season nears.
Officials with the BAER team assigned to the fire say portions of the fire burned land that was already burned in 2010 by the Schultz Fire. These projects were delivered ahead of schedule, well in advance of the winter road maintenance season, with contingency funds returned to the client.Burn Area Emergency Response team surveying damage caused by Tunnel Fire Design solutions to meet these requirements included increasing the concrete slab thickness to support the cinder piles and equipment weight and 10″ CIP concrete walls for the PEMB structure.
The client’s criteria for success included stakeholder consultation regarding ideal structure design for the most efficient circulation patterns by the cinder loading crews and a design that anticipates the wear and tear of heavy equipment operations within the structure and offers durability relative to potential accidental equipment/building impacts. To maximize the efficient application of cinders and to fulfill this critical life/safety operation, CCPW partnered with Loven Contracting and APMI to construct (2) cinder barns - one in Flagstaff (12,000SF) and one in Williams, AZ (6,400SF) - for dry cinder storage away from inclement weather. The mechanical performance of these spreaders is severely hampered when the cinders are frozen.
Coconino County Public Works (CCPW) maintains County roads during snow operations with “rock cinders” using trucks equipped with cinder spreaders.
