Next to the outfall, the new community park will feature active play areas, grassy areas for sports and recreation, multiple bike and pedes- trian paths, outdoor seating and shaded gathering places for families, access to the river, and improved safety and visibility of the park. Upon completion, Globeville Landing Outfall and Park will not only move stormwater, it will become a desired and safe place for families to gather within the community. All aspects of Platte to Park Hill: Stormwater Systems Project are currently underway with drainage functions operational and expected completion of each project throughout the next year and a half. Beyond providing flood protection for more than 5,000 residences and estab- lishing the first inhabitable stormwater outlet structure, the project will create 12 acres of new parkland in communities, add three miles of pedestrian facilities, increase open space, and breathe new life into one of Denver’s beloved golf courses.
The City opted to design an open, natural stormwater drainage system, a nationally recognized best practice for moving stormwater, and also a way to provide habitat for wildlife and ecosystem restoration while improving overall water quality. The outfall is in a key location, where much of the water from the Montclair Basin naturally enters the South Platte River. It is designed to dissipate the high-energy stream of water and features a separate and stable, impermeable lining installed three feet below the finished open channel, protecting groundwater at the outfall. It also contains a UV vault that treats low flow stormwater prior to discharging it into the South Platte River. At a location lower in the basin where stormwater concentrates, an East-West corridor extending from 39th Avenue was selected for the greenway. Photo: City and County of Denver
