特朗普签署犹他州重大灾难声明，应对野火后洪水泥石流
据EIN新闻10月8日报道，特朗普总统10月7日签署犹他州重大灾难声明，为遭受“棉白杨火灾”（Cottonwood Fire）后洪水与泥石流袭击的社区解锁联邦援助。
据报道，该声明使联邦紧急事务管理局的“公共援助”资金可用于州与地方政府及符合条件的非盈利组织，支付应急抢险与修复被灾损公共设施的费用。今夏野火留下的火烧迹地使陡峭山坡失去吸水能力，季风暴雨到来时，泥浆、灰烬与碎屑顺峡谷倾泻而下，冲入山下居民区。
州长斯宾塞·考克斯（Spencer Cox）在州损失评估确认道路被冲毁、供水系统受损、排水渠被碎屑堵塞后提出了灾难声明请求。该声明覆盖受灾最重的县，当地的清理与修复费用已让地方预算承压。
野火后洪水是西部众所周知的灾害：野火烧毁固定土壤的植被，高温还会把地表烤成拒水层。此后即便是中等降雨，也可能引发比火灾本身更具破坏力的突发洪水与泥石流。
州应急官员表示，联邦援助不仅帮助社区修复损失，还将用于降低未来风险——包括在下一个风暴季到来前稳定边坡、改善排水。该声明也为旨在降低火烧区长期脆弱性的减灾拨款打开了大门。
Trump Signs Major Disaster Declaration for Utah After Post-Fire Flooding
SALT LAKE CITY — President Donald Trump on Oct. 7 signed a major disaster declaration for Utah, unlocking federal assistance for communities hit by flooding and debris flows following the Cottonwood Fire, EIN News reported Oct. 8.
The declaration makes FEMA Public Assistance funding available to state and local governments and eligible nonprofits for emergency work and the repair of public facilities damaged by post-fire flooding. Burn scars from the summer wildfire left steep hillsides unable to absorb rainfall, and when monsoon storms arrived, torrents of mud, ash and debris swept through canyons and into neighborhoods below.
Gov. Spencer Cox had requested the declaration after state damage assessments documented washed-out roads, damaged water systems and debris-choked drainage channels. The declaration covers the counties hardest hit by the post-fire debris flows, where cleanup and repair costs have strained local budgets.
Post-fire flooding is a well-known hazard in the West: wildfires destroy vegetation that holds soil in place, and the intense heat can bake the ground into a water-repellent layer. Even moderate rain can then trigger flash floods and debris flows far more destructive than the fire itself.
State emergency officials said federal assistance would help communities not only repair damage but also mitigate future risk, including stabilizing slopes and improving drainage before the next storm season. The declaration also opens the door to hazard mitigation grants aimed at reducing long-term vulnerability in the burn area.
