The 27th Street Storm Drain is one of several large diameter storm drain projects that the City and County of Denver has identified to improve public safety by relieving drainage and flooding issues in the Curtis Park and Five Points neighborhoods. The 27th Street Storm Drain project includes approximately 5,900 linear feet of large storm pipe ranging in size from 78 inches to 96 inches in diameter.
Stormwater runoff in this rapidly developing area currently drains to the South Platte River at the over-utilized 36th Street Outfall, which can lead to flooding during storms. The new storm drain will be located in 27th Street between Blake Street and Welton Street, and in Washington Street between 27th Street and 20th Avenue.
In addition to providing flood relief in the immediate area, the new, enlarged 27th Street stormwater system will work in concert with stormwater systems along 33rd and 36th Streets to provide greater flood protection to the larger area.
When complete, the new storm drain system will connect to an existing 108-inch storm drain at the Coors Field Parking Garage at Blake Street, part of the 29th Street Outfall, balancing water flow between multiple systems and resulting in less flooding and ponded water along the 27th Street and Washington Street corridors.
Construction on Phase 1 began in October 2018 and is expected to be complete in Summer 2019.
Phase 2 construction is expected to begin August/September 2019.

Status: The finish line is in sight! Construction of the stormwater inlets in the Arapahoe intersection should be completed by the end of this week. The remaining pedestrian ramps will be installed this week as well. The final layer of paving in the Lawrence intersection will take place on Monday, June 24. Traffic will be maintained through that intersection during the work. The base and final paving of 27th — from the east side of the Lawrence intersection, through the Arapahoe intersection — is planned for Tuesday, June 25. The intersection should be reopened on Wednesday, June 26. All work is weather dependent.
The crew will be working on final punch list and cleanup items June 25th and 26th, and will be mobilizing off the site the week of July 1.
Impacts: This week, 27th is closed from the east side of the Lawrence intersection up to the alley between Arapahoe and Curtis. Please be extra aware of your surroundings as you travel through the busy construction zone. Pedestrian access is being maintained.
Colorado Rockies Parking Garage: Remember that parking is always available for $5 in the Rockies parking garage on non-game days only. Check the Rockies’ schedule so you can plan your garage-parking days!
Construction is expected to begin at Arapahoe Street and end at the west side of Welton Street. The project is set to begin in fall 2019 and be completed in the late spring/early summer, 2020.
Phase 2 Map
Traffic and other impacts of Phase 2 construction: It is anticipated that 27th will be closed to traffic, one block and one intersection at a time, between Arapahoe and Welton Streets. Traffic will be detoured onto adjacent streets as needed, but residential and business access will be maintained via secondary access points or through the construction zone.
27th Street will be closed to through traffic in sections, with no more than one block and one intersection closed at one time. Local access will be maintained. Businesses and residences may have temporary water and sewer disruptions for 6 to 8 hours. Advance notice will be provided to the impacted business owners and residents.
This will be an active construction site with open excavations and equipment in the neighborhood. Caution should be exercised near all construction operations.
The 27th Street Storm Drain project was first identified in the 2005 Stormwater Master Plan. This project is a high priority focus stormwater basin and was included in the 2016-2021 Six-Year Capital Improvement program. The project will be designed and built in stages based upon funding availability.
