Basement Flooding in Longmont: Local Conditions

Longmont is in Boulder and Weld counties, at about 4,980 feet, with drainage shaped by St. Vrain Creek and Left Hand Creek.

Longmont sits along St. Vrain Creek in eastern Boulder County. The September 2013 floods hit Longmont hard, as St. Vrain Creek overtopped its banks and cut the city in two for a time. Since then, Longmont has invested heavily in flood mitigation along the creek through its Resilient St. Vrain project.

Day to day, Longmont basements take on water from sump pump failures, storm water at window wells and foundation cracks, frozen pipes, and appliance leaks. Like nearby foothill communities, some areas can see higher groundwater in wet seasons, which makes sump capacity and backups important.

How Flooded Basement Cleanup in Longmont Works

1. 1

   Call and describe the water

   Where it's coming from, how deep, and whether it could be sewage. That sets the plan.

2. 2

   Safety check and source control

   Power, gas, and the water source are handled before anyone works in the water.

3. 3

   Water removal and extraction

   Pumps and extractors remove standing water and pull it from carpet, pad, and floors.

4. 4

   Remove what can't be dried

   Pad, wet insulation, and drywall below the wick line come out. More comes out with contaminated water.

5. 5

   Structural drying, verified

   Air movers and dehumidifiers run with daily moisture readings until materials are dry.

Seasonal Basement Flooding Risks in the Boulder County and the US-36 Corridor

The communities east of Boulder sit where foothill creeks flatten out across the plains. That geography brings flash-flood exposure during intense storms and, in some neighborhoods, higher groundwater. The September 2013 floods hit this area hard. Winters are cold enough for frozen pipes, and summer thunderstorms can overwhelm window wells and downspouts. Many homes here have finished basements, which raises the stakes when water does get in.

Insurance and Local Resources for Longmont Homeowners

Coverage for basement flooding in Longmont depends on where the water came from. The Colorado Division of Insurance explains that standard homeowners policies treat sudden plumbing damage differently from water that backs up through sewers or drains, which usually requires a water-backup endorsement, and from outside flooding, which usually requires separate flood insurance.

• For a sewer backup, contact the Longmont utilities or public works department to report it and ask whether the city main is involved. Then call a plumber about your private line.
• For gas smells, leave the house and call your gas utility from outside.
• For river or flash-flood warnings, follow local emergency alerts and the National Weather Service.
• Document everything before cleanup, and keep receipts and moisture logs.
