Jackson Street Storm Drain System

The Jackson Street Storm Drain Project will provide a critical link between the lower and upper Montclair Basin system for managing stormwater and offer improved flood protection for residents and businesses in the project area between Colfax and 12th Avenues, from Jackson to Albion Streets.

 

The Montclair Drainage Basin is over nine square miles and is Denver’s largest drainage basin without an open waterway. The result is significant, persistent flooding problems for homes and businesses during heavy rainstorms and other storm events. Rain that falls in the drainage basin becomes storm runoff that flows in a northwesterly direction, ultimately draining into the South Platte River. The Montclair Basin has been identified as a priority basin for storm drainage and water quality improvements.

Phase 1 Construction

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 5–6 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 6–7 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.

Detours and Traffic Impacts

Through traffic will be maintained for the majority of the project.

We expect 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 6–7 month period.

 
Project Status: Construction Beginning

Work for Phase 1 of the project will begin in late 2019 on the north side of Jackson Street across E. Colfax Avenue, through the parking lot at National Jewish Health, then eastward one half block on E. 14th Avenue toward Harrison Street.

There will be future design and construction for Phase 2, which will connect on the east side of Colorado Boulevard at about Albion Street near Hale Parkway.
