Recovery Updates, Longmont Flood Information

 

Longmont WorksIn September 2013, Longmont experienced the most devastating flash flood event in its history. The flood displaced hundreds of residents, and destroyed personal property, businesses and public spaces.

The flooding caused extensive damage throughout Longmont. There is much damage that will require extensive repairs - some projects will take years. The total cost of repairs to our city’s infrastructure is estimated to be $152.5 million dollars.

As we work diligently to rebuild, we want to keep you involved and informed. Here, you will find a highlight of flood recovery projects. If you would like more detailed project information, please send an email to pwnr@ci.longmont.co.us

Main Street Bridge Upgrade Q4 2014 Q3 2015 The existing bridge is currently open and safe for travel. This project addresses drainage, greenway and transportation issues by designing and constructing a new bridge structure over the St. Vrain Creek that will pass 100 year storm flows, which are not passed by the current structure. CDOT began protective measures on the Bridge foundation on Monday, 4/7. The foundation experienced scouring around the pier foundations during the flood. The bridge is safe, but protective measures are being installed to reinforce against further scour during spring runoff.
South Pratt Parkway Bridge Upgrade Q2 2016 Q4 2016 The existing bridge is currently open and safe for travel.

Sunset Street Bridge Replacement Q4 2014 Q2 2015 The approach to the bridge was washed away during the flood, so there is currently no structure or roadway to cross over the St. Vrain Creek at this location. The replacement project will addresses drainage, greenway and transportation issues by designing and constructing a new bridge structure over the St. Vrain Creek that will pass 100 year storm flows.
County Line Road Bridge Replacement Q3 2014 Q4 2014 The approach to the bridge was washed away during the flood, so there is currently no structure or roadway to cross over the St. Vrain Creek at this location.
