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 March 2019.

Status: We expect to open one lane of Walnut at the end of this week. Pipework through the 27th and Walnut intersection continues. Asphalt paving of 27th — from the east side of the Blake and 27th intersection to Walnut — is expected to begin at the end of next week.
The new staging area for the crews at 27th and Lawrence is being prepped as the current staging area near the parking garage is being cleaned up. Concrete paving from the current staging area access to the garage entrance is set to begin at the end of this week. Manhole work is still ongoing on 27th Street—mid-way between Blake and Walnut—and in two other locations around the Walnut and 27th intersection.
Next week crews will also begin potholing on 27th between Walnut and the alley past Larimer.
Impacts: The mid-block closure of 27th Street—between Blake and Walnut—is still in effect. One lane of the Walnut / 27th intersection will open at the end of the week. The temporary two-way traffic configuration will be taken down with the lane opening. Remember that pedestrian access is being maintained in the construction area.
Car Share Signage: There are two Car Share signs is place, one directly south of Joe’s Liquors (2644 Larimer), and one on the NW corner of Larimer and 26th, in front of Il Posto. With construction impacts, this can make drop off/pick up easier for visitors and business patrons.
Parking Garage: Check it out! Only $5 for all-day parking! The Rockies garage is a great alternative to street parking!
Construction Coffee: We hope to see you at the next Tuesday, February 26th at The Denver Central Market (2669 Larimer) from 10:30 - 11:30. As always, we will be sitting inside the front door to the left.
Open for Business! Throughout construction, please keep in mind there are many amazing local businesses along Walnut that are open for business! Stop into Osaka to warm up with some ramen, and then head over to Voicebox for a sing-along and a drink. Enjoy a one-of-a-kind jazz experience at Nocturne and get some cool new tech and apparel at Digitiqe and Fice! These businesses (along with many more) in RiNo love and appreciate your continued support throughout construction.
Due to high traffic volume and below-ground utility density, stormwater pipe installation will take place by tunneling beneath Blake Street. The work between the Coors Field parking lot and Walnut Street cannot begin until the Colorado Rockies 2018 season has ended and must be completed by the Saint Patrick’s Day Parade in March 2019.
Beginning at the 27th and Blake Street intersection and heading southeast, 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.
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.
