Denver Public works will be installing an improved, expanded storm drain system to provide greater flood protection for Congress Park residents, National Jewish Health (NJH) patients and staff, and local businesses from heavy rainstorms and other storm events. In addition, the expanded and improved Jackson Street Storm Drain System will ultimately provide additional capacity for the upstream area around Hale Parkway.
Construction will start toward the end of 2019 at the intersection of E. Colfax Avenue and Jackson Street. The plan is to keep at least one lane of traffic open, each way, during this 3-4 month phase of construction.
For the next 8-10 months, crews will continue to install the storm pipe through National Jewish Health’s parking lot to E. 14th Avenue and Jackson Street.
Beginning in late 2020/early 2021, it is expected that storm pipe construction will then proceed east along E. 14th for half a block toward Harrison Street. This segment should be completed in 3-4 months. New storm inlets will be added at E. 14th Avenue between Jackson and Harrison Streets.
Phase 2 design and construction will eventually add an enlarged system to connect on the east side of Colorado Boulevard at about Albion Street near Hale Parkway.
Waste Water Management expects full lane closures will be required on E. 14th Avenue in the area around Jackson and Harrison Streets during the final phase of the project to ensure the safety of the construction crews as they install the new pipe. Detours will be put in place for this 3-4 month period.
