Sinkhole reopened

Record-breaking rainfall in the spring and summer of 2023 stressed Littleton’s stormwater infrastructure, causing several aging corrugated metal culverts to collapse beneath city roadways, parks and open spaces.  

Crews are hard at work replacing failed metal storm sewers with reinforced concrete pipes, which will increase durability and resilience. City engineers are proactively examining other elements of Littleton’s stormwater infrastructure to prevent further issues.
