27th Street Storm Drain Project

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. 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.

Phase 1: 2017-19

The first phase of design and construction is funded and consists of the downstream portion of the project: 27th Street from the 108-inch storm sewer connection point beginning at the Coors Field Parking Garage and continuing several blocks to end between Walnut and Arapahoe streets, as determined by the final design and other factors.

Phase 1 is currently in the final design stage. Construction will begin in late summer or fall of 2018 and go through the spring of 2019.

To accommodate the Colorado Rockies baseball season and the Denver St. Patrick’s Day Parade, construction will not occur in 27th Street between the Coors Field Parking Garage and Walnut Street prior to November 1, 2018 or after March 16, 2019.

Phase 2

The next phase is tentatively scheduled for construction in 2019-2020. The remainder of the project will be further divided into phases based on available funding.
