Marshall declares emergency after concentrated storm; county-run debris site open and no-charge

Marshall city and Lyon County officials declared an emergency and activated the city’s emergency operations center after a severe, highly localized storm event that caused flooding across parts of Marshall. Mayor and staff described unusually concentrated rainfall on Friday evening that produced localized totals the National Weather Service described as having less than a 1% probability. City staff said wastewater flows at the treatment plant peaked at roughly eight times normal for the event and that both stormwater and sanitary systems were overwhelmed in affected neighborhoods. Emergency management staff worked jointly with county counterparts. County environmental services established a debris collection site for flood-damaged materials; staff said the site is open through the end of the week, Monday–Friday 3 p.m.–7 p.m., and Saturday 9 a.m.–3 p.m., and is provided at no charge for flood-damaged items. County officials are coordinating volunteer registration and worker protections via county systems. City staff reported they have identified about 300 properties so far and estimate the final count may be closer to 600; many affected basements are not visible from the street. Officials urged residents to report flood damage via the city’s online form so state and federal officials have accurate damage counts for possible assistance. Council and staff urged caution when remediating flood-damaged homes, noting risks from hidden damage to drywall, appliances and furnace equipment and advising homeowners to use qualified professionals. Staff said they are coordinating with the state and the county and continue to assess potential funding or assistance options.
