"Longmont: Flood Bonds Sail Through" - Times-Call, 6/24/14


What Are Voters Being Asked to Do?

The City of Longmont is asking voters to approve the issuance of $20 million in bonds to fund storm drainage improvements that are needed for future flood mitigation. The improvements will include channel restoration along St. Vrain Creek from just west of Hover Road to Martin Street, as well as other necessary infrastructure upgrades to enable the creek to pass 100-year flood flows.

Record of Past Flood Mitigation Projects

In 2007, voters approved a bond issuance to fund the following flood mitigation projects:

  • Left Hand Creek Flood Control Project in Southmoor Park – Completed
  • Lykins Gulch Project – Completed
  • Spring Gulch #2 – Completed
  • Highway 66 Detention Pond - Completed


Longmont Times-Call, 9/21/2013, Reporter Scott Rochat

“The [September 2013] flood actually put two major flood improvements to the test, both completed within the past four years. The Left Hand work widened and deepened the channel near [Southmoor Park], replacing the South Pratt Parkway Bridge and adding culverts under Main Street. Meanwhile, a 2009 project at Lykins Gulch aimed the waterway at Golden Ponds rather than have it hit a small ditch at Airport Road and spill over the surrounding landscape.”

Extending Flood Protection to St. Vrain Creek

If the 2014 Storm Water Bond issuance is approved, the City of Longmont will be able to construct the first phase of flood mitigation measures along St. Vrain Creek. The planned stream channel modifications and infrastructure upgrades along St. Vrain Creek will further protect Longmont from future flood damage, just as the previous projects along Left Hand Creek and Lykins Gulch helped to minimize damage in the 2013 flood.

How Much Will This Cost?

The cost to make St. Vrain Creek capable of holding a 100-year flood all the way through Longmont has been estimated at $65 - $80 million.

If voters approve the bonds for $20 million, the City of Longmont will be able to combine that money with other available funds to locally support $48 million in flood mitigation efforts.
