27th Street Storm


 

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.

 
 
Project Status: Phase 1 Design

Phase 1 of the project is out for bid, with construction expected to begin in Fall 2018.


Council District: 9

Neighborhoods: Curtis Park, Five Points
RiNO Business Improvement District

Timeline

  • 2005: Identified in Storm Drainage Master Plan
  • 2015: Preliminary Design
  • 2017/18: Final Design
  • 2018/19: Construction, Phase 1
 

What to Expect During Construction

Phase 1: It is anticipated that construction will begin at Blake Street in the Coors Field parking lot, and the goal is to reach the 27th and Arapahoe Street intersection, pending funding.

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.

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. 

Features

  • Underground stormwater facilities including a water quality trash vault at Walnut Street to remove large pieces of trash before stormwater continues to the South Platte River
  • New and upgraded storm inlets to allow larger volumes of stormwater to enter the storm drainage system faster and more efficiently
  • New curb ramps in 27th and Washington Streets to comply with current ADA requirements 
  • Reconstruction and repaving of 27th and Washington Streets with improved street drainage

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.
