Globeville Landing Outfall Redesign

Great Ecology is the ecological consultant to Merrick & Company on the design and restoration of the Montclair Creek Outfall Project. The Creek lost most of its ecological function due to decades of impacts from urbanization and has mostly served as a stormwater conveyance system, including channelization and being forced underground in pipes. As part of the Platte to Park Hill stormwater retrofitting project and revitalization of the National Western Complex (NWC) in Denver, the project daylights Montclair Creek near its confluence with the South Platte River, just south of the Denver Coliseum. Part of the project site is within the former Vasquez Boulevard and I-70 Superfund Site (delisted in September 2019) as well as other contaminated areas along the South Platte River. These environmental constraints required the newly created channel to be contained within an impermeable barrier system to prevent hydrologic connection with the contaminated substrate and groundwater.

Great Ecology provided ecological and design expertise, as well as construction oversight, on the creation of the stream open channel, park integration, and floodplain connectivity. Great Ecology’s design was based on the ecological functionality of native streams and rivers and integrated the needs of the local community and NWC. Great Ecology supported the channel design, including construction details and specifications for channel substrate, growth media, and plant community composition. The revegetation approach within the channel included an innovative strategy that modified soil chemistry to minimize the establishment of invasive weeds and encourage native species growth. The completed project will create a new, functioning stream channel, add additional park space to Globeville Landing Park, and restore part of the South Platte River floodplain, providing residents and visitors with a valuable natural resource within the Denver Metropolitan area.
