Stormwater Improvement Projects#
Mulberry Riverside Drainage Improvements and Cowan/Myrtle Waterline Replacement
In 2018, storm drainage improvements were installed in Cowan and Myrtle streets near Mulberry Street and Riverside Avenue. Construction of an outfall structure near the Poudre River and Springer Natural Area was included.
Clearview Channel Rehabilitation
The Clearview Channel Rehabilitation project between Briarwood Road and Hillcrest Drive began in May 2014. Utilities Stormwater crews rebuilt the channel to repair eroded areas, prevent future erosion, improve maintenance access and enhance channel habitat.
Boxelder Stormwater Improvements on Prospect Road
Fort Collins Utilities began construction of stormwater improvements under Prospect Road near Boxelder Creek in March 2016. At the same time, City Engineering began replacement of an existing bridge over Boxelder Creek. Both projects were built under one road closure (Prospect Road) to minimize traffic impacts.
Spring Creek at Edora Stream Restoration
Fort Collins Utilities and City Engineering worked to replace the bridge over Spring Creek at Edora Park and improve and restore the creek.
Dry Creek Drainage Improvement Project
The Dry Creek Drainage Improvement Project was constructed to protect people and properties within the Dry Creek Basin and reduce or eliminate the FEMA regulatory floodplain for Dry Creek in the city limits.
Northeast College Corridor Outfall Phases 1 and 2
Utilities is improving storm drainage as part of the ongoing Northeast College Corridor Outfall Project (NECCO). Portions of the floodplain in the Alta Vista neighborhood were removed as a result of these improvements.
Canal Importation Ponds & Outfall Project
Construction on the Canal Importation Ponds & Outfall (CIPO) Drainage Improvement Project began in fall 2007. The completed project greatly reduced flood risk east of the New Mercer Ditch.
West Vine Outfall Project
In 2003, the City of Fort Collins and Larimer County adopted the West Vine Basin Master Drainage Plan. Improvements to help alleviate flooding during a 100-year storm, including detention ponds, channels, storm sewers, culverts and spill structures from the irrigation canals.
Plum Street Sanitary & Storm Drainage Improvements Project
In coordination with The District at Campus West development on Plum Street, Fort Collins Utilities removed, replaced and up-sized portions of the existing sanitary sewer line and storm drainage system along Plum and Shields streets and City Park Avenue.
Lincoln/Willow Storm Sewer Upgrades
From January 2015 - May 2016, Fort Collins Utilities replaced old and undersized storm sewer infrastructure in the Downtown River District. The project improved drainage, added water quality treatment and increased safety for area properties and transportation systems.
Mail Creek Stream Rehabilitation Project
Stream rehabilitation and/or restoration projects repair areas of streams where the ecology, safety, structure and water quality have changed over time. The Mail Creek Project will reshape and stabilize the eroding banks along a specific section of Mail Creek to improve safety and habitat.
Remington Street Stormwater Improvements & Sewer Line Replacement
An undersized stormwater system and aging sanitary mains were replaced in Remington Street from Spring Park Drive to Prospect Road from February to August 2020. This project improved wastewater operations and drainage and flood protection in the neighborhood.
Downtown Stormwater Improvement Plan (DSIP)
Downtown Fort Collins is at risk for flooding, and pollution from urban stormwater runoff from downtown can impact the Cache la Poudre River. DSIP will address the five major stormwater projects remaining in the downtown area.
Poudre River Bank Improvements
Streambank erosion in recent years had resulted in an area of severe bank erosion along the Poudre River near Homestead Natural Area. Utilities construction crews started reconstruction of the damaged bank December 2019, rebuilding 250 linear feet of the riverbank along the northwest side of the Homestead Natural Area.
Skyline Storm Sewer
The Skyline Storm Sewer Improvement project replaced an undersized deficient storm sewer in 2018 along Skyline Drive east of Crestmoore Street. This location had documented history of minor flooding. While the previous storm sewer failed to effectively convey even a 2-year storm runoff, design and construction of the new system was optimized to convey up to a 10-year storm, providing additional protection to surrounding properties and homes.
Hollywood and Irish Detention Pond
The Hollywood and Irish Stormwater Improvement Project was completed in the early 2000’s through Hazard Mitigation Grant Funding awarded to Larimer County. Homes in the area of Hollywood and Irish streets experienced severe flooding and property damage from storms in 1992, 1997 and 1999. The drainage improvements included construction of a regional detention pond, outfall channel and improvements to roadside ditches, which removed over 60 structures from the floodplain.
Sheldon Lake Drainage Improvement
This project consisted of numerous drainage improvements in the area north of Mulberry Street and west of Sheldon Lake. Additional stormwater detention was provided in the City Park Golf Course and in Sheldon Lake. Uncontrolled stormwater spills were eliminated from the New Mercer Ditch and the Larimer County Canal No. 2 between Mulberry Street and the West Vine/Canal Importation basin boundary.
West Prospect Ponds
Completed in 2006, this project included stormwater drainage improvements that eliminated overtopping of detention ponds, which resulted in more than 120 homes being removed from the 100-year floodplain. The overall project limits began at the southwest corner of West Prospect Road and Overland Trail on the City-owned property and extend north to the Minatta/CSU property line west of Overland Trail.
Scenic View and West Orchard Ponds
The 2009 West Orchard and Scenic View pond improvements were initially recommended for the Plum Channel as part of the 2001 Master Plan. Significant flooding occurred in this area within residential neighborhoods and at roadway crossings. Improvements were constructed from Kimball Road to Ponderosa Drive to mitigate flooding. Improvements alleviated unrestricted runoff and overflow spills that caused significant flooding during major storm events.
