33rd Street Outfall

The 33rd Street Outfall project installed a storm sewer system to service the neighborhoods of Five Points, Whittier, and City Park West. This improves drainage during a five-year storm event and addressed areas where significant flooding could occur. The new storm system carries storm runoff and snowmelt safely to the South Platte River, reducing the risk of damage to residential and commercial properties. It also allows additional improvements to connecting systems upstream in areas to the east, which are also at increased risk of flooding.

Overall project construction was completed in December 2019.

Globeville Stormwater Systems Study

The Globeville Stormwater Systems Study was a culmination of an extensive effort by the City and County of Denver, in partnership with the project team, the community, and stakeholders to better understand the causes of flooding in the area; explore solutions for river and local stormwater flooding; and to identify the preferred neighborhood solutions that alleviate flooding and provide multiple community benefits.

Project Status: Study Complete

Study area: The Globeville-Utah Junction drainage basin includes Globeville, Heron Pond, Carpio-Sanguinette Park, portions of the Sunnyside neighborhood, and portions of the Chafee Park neighborhood.

To begin the study, the team worked with the community to understand existing conditions in Globeville. The study gathered data to identify potential long term and short term solutions for stormwater management in the basin.

Recommendations


A: 51st & Zuni Park Space: Implement water quality and moderate detention opportunities.

B: Detention and Park Space: Identify and implement detention and potential park opportunity located along the stormwater runoff path before it gets to Globeville. Potential areas could include areas marked B1, B2 and B3. 

C: Project L Pipe: Implement Truncated Project “L” pipe improvement along Jason Street alignment to the South Platte River.

D: 48th Avenue Green Corridor: Further study and implement new stormwater pipe along 48th Avenue with a new outfall at the South Platte River; a stormwater overflow management area at Argo Park and green infrastructure and mobility improvements along 48th Avenue to Washington Street.

E: Flood Protection from the South Platte River: Design and implement improvements to the height of the existing levee and extension of levee from 38th Avenue to approximately 35th Avenue along Ringsby Court. Levee Improvements and extension coupled with a vision for neighborhood amenities along the river.

In addition to the project recommendations, this study emphasized strategies to increase community education and awareness around local flood concerns, and ways for individuals and property owners to protect against flood risk.

Sanderson Gulch

The Sanderson Gulch stormwater project improved the drainage system between Lipan Street and the South Platte River. Construction of the new, higher-capacity drainage system consists of underground, large-capacity stormwater box culverts (large pipes) to manage high-water flows during large storm events. The culvert system is combined with a naturalized, open-channel on the surface (between the railroad tracks and Platte River Drive) designed to convey and filter base flows and runoff from smaller storms and improve drainageway habitat.

Construction began in February 2018 and was completed in December 2019.

Upper Montclair Basin: Stormwater Systems Study

The Upper Montclair Basin measures nearly six square miles, stretching from Fairmount Cemetery to City Park. The basin is fairly flat and prone to flooding at certain low points. Without an open waterway, the current stormwater drainage system needs to be improved in some key areas; localized flooding has been a problem in this area for decades. This basin has been identified as a priority basin for not only storm drainage improvements, but also water quality improvements. To address the unique challenges of this basin, Mile High Flood District (MHFD) and the City and County of Denver partnered to complete this stormwater systems study, and subsequent concept design process, to identify and recommend key projects that improve local conditions.

Project Status: Study Complete

Study Area

The Upper Montclair Basin stretches southeast from City Park to Fairmount Cemetery. This portion of the basin encompasses many Denver neighborhoods including: South City Park, the southern portion of Park Hill, East Colfax, Congress Park, Hale, Montclair, Crestmoor, Hilltop, and a small portion of Washington Virginia Vale.

Study Goals

  • Develop a new approach to stormwater planning in Denver that empowers the community
  • Reduce the impact of flooding associated with minor to moderate storm events and improve water quality throughout the basin through implementable solutions
  • Think critically and creatively about stormwater resiliency in a built, urban environment
  • Develop alternative concepts and solutions that integrate community interests and provide community benefits
  • Increase public education and awareness of the community’s role in adopting to flood conditions in the built environment

Located on the map above, the study identifies four improvement areas that can reduce local flooding risk while building upon local assets. These areas were carefully selected through community collaboration and community planning and are designed to create a significant improvement in flooding and water quality.
