WALERT field teams assessed the fire areas between August 31 and September 2.According to the report, significant rain, rain-on-snow and rapid snowmelt could send runoff quickly into gullies and channels near residences, roads and other infrastructure. It also said even smaller runoff events could create dangerous conditions in some places.For the Autumn Lane Fire, the report said debris flow risk was generally low, but pre-fire mudslides, flooding and rockfall had already been documented in parts of the burn area. It said concerns were highest near drainage outlets, below steep slopes and along State Route 291, where falling rocks and runoff could affect drivers and nearby properties.The report said transportation managers should inspect culverts and watch for sediment buildup that could worsen flooding. It also said temporary warning signs may be worth considering along SR 291 and West Rutter Parkway.In the Old Trails Fire, the report said urban stormwater controls added after the fire may create new hazards in some neighborhoods. It recommended the City of Spokane carry out regular ongoing monitoring to identify places where runoff could be redirected into unintended areas while filters, wattles and other controls remain in place.The report also pointed to localized concerns in the Old Trails burn scar near homes, trails and sections of SR 291. It said debris flow danger remained low overall, but residents near gullies and alluvial fans should be aware of possible increases in runoff, erosion and sediment.For the Fairview Fire, the report said only one basin was modeled with a moderate combined debris flow hazard and that most hazards appeared only slightly elevated by post-fire conditions. It recommended monitoring a road culvert and a drainage system through an earthen structure after significant runoff events to reduce the chance of blockage and downstream problems.The report said residents living on alluvial fans or near streams flowing from burned areas should understand that flash flooding and debris flows remain possible until vegetation recovers.
