Summit County details spring runoff plans: sandbags, cameras and alerts as snowmelt begins

Summit County officials told the Board of Health on Monday they are stepping up preparations for spring runoff and possible flooding as the snowpack begins to melt. Catherine McMullen, who led the briefing alongside Bridget Conway from county communications, said teams have been mapping “critical nodes” — culverts, splits and points of collection — and coordinating multi‑agency resources to clear and protect infrastructure.

“We have about 27,000 sandbags in Summit County public works,” McMullen said, adding that Park City currently holds about 30,000 and that the county just received approval for 80,000 additional state sandbags to be delivered this week. Officials said sandbag inventories were informed by conversations with jurisdictions that responded to the 2021 Cedar City flooding and by measurements of local hydrology.

The county also has requested live‑view (LVT) camera stations at four high‑risk locations and is working with state hydrologists and meteorologists to monitor soil moisture, stream flow and short‑term forecasts. Conway said the county has published a public information hub at summitcounty.org/flooding with details on emergency alerts, sandbag locations and guidance for homeowners, and that outreach materials will be translated into Spanish.

Board members pressed for operational clarity. McMullen and Conway said sandbag sites are mostly self‑serve: bags and sand are staged at about a dozen locations across the county, residents and businesses may fill their own bags 24 hours a day, and some municipalities (Park City) have set per‑household limits (Park City’s limit was cited as 25). Officials plan volunteer and city‑led sandbagging events as the snow recedes and said public works crews are proactively pre‑filling where available.

On alerts, McMullen said the county will coordinate with NOAA’s weather products for watches and warnings and use its Everbridge/NotifyMe system for life‑safety or targeted, opt‑in advisories. "If it is immediate life safety — you could drown or there's an area that needs to be evacuated — then it'll be an Everbridge emergency alert," she said.

Public‑health implications were also flagged: Phil (department staff) told the board that small drinking‑water and wastewater systems on the county’s east side are already experiencing high groundwater infiltration, with one system pumping about 35,000 gallons a day versus a normal 4,000 — a change that can overwhelm drain fields and trigger boil notices. McMullen added that sandbags exposed to floodwater that contacts sewage may require special hazmat disposal and that the county is preparing for damage assessment, FEMA‑level training for executives, and expanded incident reporting.

The county urged residents to review flood‑insurance waiting periods and to take property‑level steps (grading, window‑well protection) since local agencies cannot protect every private residence. Officials said they will continue issuing weekly situation reports and increase distribution if an incident occurs.

The Board asked for a follow‑up briefing in May as temperatures rise and the melt accelerates.
