Overview:
The Oak Street Stormwater Improvements Project was one of several stormwater projects that was identified as part of the overall Downtown Stormwater Improvement Program and will contribute to resolving the urban flooding issues in downtown Fort Collins. This project is an extension from the Oak Street Outfall constructed in 2001. It extends west on Oak Street from Mason to Jackson Street. The project included alternative analyses/master planning efforts, final design, preparation of construction specifications and contract documents, CLOMR and LOMR submittals utilizing PC-SWMM 2D, as well as resident engineering.
Project Components:
Approximately 11,000 linear feet of new stormwater mains were designed, ranging in size from 12-78 inches in diameter. This includes several “lateral” extensions from the main spine on Oak Street, north to Mountain Avenue or south to Olive Street, that connect to existing storm lines and improve inadequate drainage at these locations. In addition inlets were proposed/designed at 58 separate locations. Finally, the final design also included four rain gardens and intersection improvements focusing on water quality and bike/pedestrian safety along the project route.
Design Team:
J-U-B staff collaborated with City of Fort Collins Staff, BHA Design to provide Landscape Architecture, Brierley Associates for tunnel design and geotechnical engineering, AVI for SUE and Survey and PEN Engineering for structural design to bring this project to a successful conclusion.
