Matrix was selected by the Park Creek Metropolitan District to provide infrastructure planning, programming, and design for the redevelopment of the former Stapleton International Airport. When completed, the metro district will have invested over $800M in new roadway and utility infrastructure to support over 4,600 acres of master planned communities.
Stapleton is the largest urban infill project in the nation and emphasizes city living and urban design within a transit oriented development scheme. Matrix provided overall infrastructure planning and programming consulting services to the City and County of Denver, Park Creek Metro District, and Forest City Stapleton, Inc. for all master planned improvements. This is in addition to providing engineering design services for Martin Luther King and Central Park Boulevards; Havana and Spruce Streets; 26th, 29th, 35th, and 49th Avenues; and Smith Road.
Transit, bike, and pedestrian connections to parks, open space, neighborhoods, and employment centers were central to the design fabric of all Stapleton-related improvements.
The Matrix team designed 29th Avenue—an approximate one-mile segment between Quebec Street to the east of Yosemite Street in Denver. Plans were approved by the City and County of Denver as part of the first phase of Forest City’s development of the former Stapleton International Airport property.
The infrastructure design for the roadway served to integrate the Stapleton Infrastructure Master Plan and the Stapleton Preliminary Concept Plan while incorporating a “town green” concept catering to an urban, pedestrian oriented area. 29th Avenue provides for a pedestrian friendly gateway to the town green with extra wide attached sidewalks, on-street parking, handicapped accessible loading zones, and street intersection bulb-outs. The town green itself features one-lane, one-way couplets in an elliptical shape for counterclockwise traffic flow allowing for landscaping in the center and transitioning to a 60-foot wide raised median section emphasizing wide planting areas with gravel and paved sidewalks.
The main element of the project includes roadway construction, right-of-way delineation, and major underground utility design, including sanitary and storm drain outfall for the watershed. A highly challenging component of the project involved investigating alternatives to resolve the technical and safety concerns of the City and County of Denver while maintaining special design features envisioned by the urban planning team.
