About Globeville Landing Outfall and Park

The Globeville Landing Outfall (GLO) project includes a redesign of Globeville Landing Park combined with a new storm water open channel connecting to the South Platte River. The overall project is referred to as an ‘outfall’ because this is the location where the storm water enters (or ‘outfalls’ to) the South Platte River. This project is essential to improving flood protection in the areas addressed in the Platte to Park Hill Stormwater Systems plan, and is scheduled to be completed first in order to safely receive storm water from the other project areas. 

A new open channel design will help clean storm water naturally when possible and will move the water to its ultimate destination, the South Platte River. The project will include work to expand and redesign Globeville Landing Park, making it a more desirable park for the community by:

  • improving connectivity
  • reclaiming the concrete culvert as park land
  • adding a natural open channel with vegetation that will move storm water safely
  • improving the overall park design

Construction Updates

Please use caution near the work zone and follow any posted detour signs in the park and on adjacent roads. McFarland Drive is now open from Arkins Ct to 44th Street.


The construction for GLO will run through the Vasquez Boulevard/I-70 Superfund site (a site where land has been contaminated). During construction, the City and County of Denver, with the Colorado Department of Public Health and Environment, and the U.S. Environmental Protection Agency will coordinate to monitor and minimize odors or impacts to air quality.

Planning for the Globeville Landing Outfall project began in summer 2015. The project will have two interrelated elements — drainage design and the park redesign.

Design for the drainage elements is now underway, including the detailed design of the pipes, open natural channel, and topography of the park.

Planning for the redesign of the park has also advanced, but is still in the concept planning phase. Public outreach efforts for the park have focused on understanding how area residents use the park today and how they would like to use the park in the future. Through this understanding, the team is developing concept park designs incorporating as many of the desires of the community as possible. Additional public outreach is planned for summer 2016 to examine ideas for the park’s use and how this will translate into a new park design. Once a single park design concept is identified and publicly reviewed, the project will advance to final design and construction.

The team has engaged with many local residents, businesses, park users, and other stakeholders since the project kicked off in summer 2015. We have heard constructive feedback which is informing the development of the draft park design concepts. Several of the key themes that have been expressed by stakeholders consistently include:

  • Create an active play area with a playground of some type
  • Create a grassy area for informal play (soccer, football, field games)
  • Provide multiple Bike/Pedestrian connections, connectivity from park to neighborhoods
  • Provide outdoor seating, grills, and shade as gathering places for families
  • Provide access and views of the river
  • Save trees and maintain the existing land forms within the park.
  • Provide restrooms
  • Improve safety—concern that the park currently has poor visibility and is isolated

Multiple public meetings, stakeholder interviews, focus groups, youth engagement events, etc. have provided a strong understanding of how important this park is today and how it can be improved to better serve the community.

Planning for the drainage elements of Globeville Landing Outfall began as part of the National Western Center master planning process. The idea of a natural open channel and water quality to create improved park space was considered through the National Western Center’s process. In the transition from planning to design, the Globeville Landing Outfall project was moved under the Platte to Park Hill Stormwater Systems program.

The drainage function of the Globeville Landing Outfall project is to safely and efficiently move storm water from approximately 40th Street and Blake Street to the South Platte River at Globeville Landing Park. This outfall is in a key location, where much of the water from the Montclair and Park Hill basins naturally enters the South Platte River. Because Globeville Landing Park was originally constructed to serve as both a park and a drainage outfall, much of the storm drainage pipes and facilities north and east of downtown Denver point toward the park today.

The Globeville Landing Outfall includes a combination of underground pipes and natural open areas to move storm water. At 40th and Blake streets storm water would enter a very large pipe to move the water under the commuter rail and freight railroad tracks northeast of Blake Street. Traveling northwest, the underground pipe crosses under a portion of the Pepsi facility and the Denver Coliseum parking lot. The pipe then rises to the surface and becomes a natural open drainage channel, on the southwest edge of the Coliseum parking lot.. The open, natural channel (no longer a pipe) passes through Globeville Landing Park making its way to the South Platte River.

The Globeville Landing outfall currently includes a pipe that delivers storm water into an open concrete lined and fenced channel. As part of the Globeville Landing Outfall project, the concrete lined and fenced channel will be replaced with the open, natural channel in a new alignment.  Both the existing outfall from the Coliseum parking lot and the new outfall will deliver storm water through the open natural channels. These two channels will join to form a single open channel in the park before it meets the South Platte River.

Open drainage systems in the form of natural open channels are considered national best practices to manage storm water. These channels also provide opportunities to help naturally clean storm water as it flows through the natural open channel (referred to as ‘water quality’); restore natural ecosystems; create wildlife connections; and better control storm water to improve safety.

The current concrete drainage channel will be replaced with a natural open channel. By enhancing the drainage system, trails and vegetation can be incorporated to provide an attractive and safe space for people to commute and recreate. The vegetation will enhance the habitat for wildlife, while allowing water to filter through to naturally clean the water and improve water quality. Excess nutrients in the storm water (fertilizer/plant food) will be taken up by vegetation in and around the Globeville Landing open channel and other channels upstream to deliver cleaner water to the South Platte River.

In general, water-borne bacteria need water to stay alive. Open channels expose water borne pathogens to sunlight and prevent them from proliferating. At Globeville Landing, storm water will remain separate from area ground water thanks to a stable, impermeable lining installed three feet below the finished open channel. Open channels are generally safer than large underground pipes as they slow and control storm water across wider channels and gentler banks.

 
Project Status: Design & Construction

Design refinements to the preferred park concept are being made. Construction of the natural channel at Globeville Landing Outfall will begin in the winter of 2016/17. Closure of Globeville Landing Park is anticipated to begin in late December 2016 for drainage improvements. Construction of Globeville Landing Park improvements should begin late 2017.
