The Square on 21st


What's New

Relive the summer on the Square on 21st! In an effort to capture what it took--from city staff, neighbors, local artists, community partners and area businesses--to turn a street into a temporary park, we created a video to document the summer on The Square on 21st!

Our goal was to tell the story of the idea, the design, the need, the community buy-in and the fun that resulted from this two-month experiment to test new ideas and encourage the public to think about how we use our streets and open spaces. Watch the video below (or on YouTube) to learn about the history of the project, relive your favorite moments and see key data points on the park's impact on the neighborhood and Downtown Denver.

Don't forget to share the video and tag it #thesquareon21st!

After a successful summer that saw more than 15,000 visitors come to the Square on 21st, a pop-up park between Larimer and Lawrence Streets, traffic is returning to the downtown block this weekend. The park, a collaboration between the City and County of Denver and the Downtown Denver Partnership, showcased how underused public right-of-way can be activated and transformed, and it provided a park-like public space in a neighborhood that lacks these types of spaces.

About the project

The Square on 21st is scheduled to be open from June 15 to August 15 and will provide a temporary gathering place for a neighborhood that doesn’t currently have open or public spaces. Those who live and work here will have an opportunity to enjoy amenities they usually have to leave the neighborhood to access. The square will increase street-level activity and encourage area residents, commuters and visitors alike to consider Denver’s urban spaces in new ways.

The installation urges visitors to consider new and creative uses for publicly-owned streets and sidewalks. It is the direct result of a series of city plans, including the 21st and Wynkoop Urban Design plan (2016), as well as The Outdoor Downtown, a plan for downtown’s parks and open spaces. Visit to learn more.

The Square straddles the Ballpark and Arapahoe Square neighborhoods and has the support of local neighborhood associations, as well as the Downtown Denver Partnership and a multitude of event sponsors.

The Square on 21st is also part of the larger Downtown Loop project. Click here to learn more.

21st Street Demonstration Project

The Northeast Downtown Neighborhoods Plan, adopted in 2010, recommends revitalization of 21st Street to create a destination for the Arapahoe Square and Ballpark neighborhoods. This includes multi-modal improvements along the entire length of 21st Street and a festival street on 21st Street between Blake Street and Lawrence Street. It further describes the lack of public parkland in the neighborhood and clearly identifies the importance of public park space in order to create a vibrant livable neighborhood on the edge of the downtown core.

In 2015, the city partnered with the Downtown Denver Partnership and the Colorado Rockies to further identify the vision and urban design plan for 21st Street. To test the design concept and achieve maximum benefit for Downtown Denver, the city would like to use this next phase and budget to fund a demonstration project to test the feasibility of ways to design 21st Street as an active public realm where the pedestrian is the priority and is conducive to frequent special events and game day festivities. Concepts tested will include creative solutions such as new and expanded streetscapes, pedestrian seating areas, easily adaptable special event tents, bike corrals, street closures and other methods. This effort will require a strong partnership and support between Community Planning and Development, Parks and Recreation, the Public Works, Downtown Denver Partnership and Ballpark neighborhood residents and stakeholders, and will innovate the way we think about public space in our city.

Urban Design Plan Process

Together with the Downtown Denver Partnership and the Colorado Rockies, the City and Country of Denver is developing a conceptual design for 21st Street (Benedict Fountain Park to Coors Field) and Wynkoop Street (Cherry Creek Trail to the Ballpark) that balances the needs of all users and enhances these streets as two of Denver’s premier destinations for residents and visitors alike.

The urban design plan will specifically:

  • Help create signature streets within the neighborhood(s) 
  • Pilot various innovative stormwater best management practices 
  • Improve the game day experience for guests to Coors Field 
  • Connect with other key destinations, and the overall public realm experience 
  • Facilitate reinvestment in underutilized properties 
  • Enhance the overall public realm experience 

Additionally, the project will develop an implementing plan for the urban design plan, including cost estimates and a phasing strategy.

Urban Design Plan Stakeholder Advisory Group

Denver planning projects are typically guided by a steering committee comprised of stakeholders within the plan area and surrounding community. These stakeholders typically include representatives from registered neighborhood organizations, public and nonprofit agencies and business improvement districts, pedestrian and bicycle advocacy groups, as well as City Council members, property owners and business owners. The members of the advisory group are responsible for reporting back to their representative organizations and keeping their members up to date with the project.

Meetings will take place at these three milestones:

  1. Existing and future use and programming 
  2. Conceptual design 
  3. Detailed design for Festival Street section(s)
