Remington Storm Sewer Improvements
Project Summary
The Remington Street Storm Sewer Outfall Improvement Project (RSO) involved the preliminary and final design of improvements to an existing storm sewer system in central Fort Collins. Stormwater collected by the RSO originates near the Colorado State University campus and is conveyed south to Spring Creek. The primary goals of this project were to reduce potential flood damage, increase public safety by alleviating stormwater ponding along roadways during storm events, and increase water quality of the stormwater being discharged to Spring Creek.
