Denver Public Works repairs and improves public streets wtih services that include paving, pothole patching, curb and gutter repairs, and curb ramp installation, as well as maintenance tasks such as street sweeping and snow removal.
Denver is taking a comprehensive approach to better protecting people and property against flooding while improving water quality and enhancing public spaces. The Platte to Park Hill: Stormwater Systems program is focused in the near-term on the northern neighborhoods of Elyria, Swansea, Cole, Clayton, Skyland, Whittier, Five Points and Northwest Park Hill. The City began planning this phased effort in Summer 2015.
The 27th Street Storm Drain is one of several large diameter storm drain projects that the City and County of Denver has identified to improve public safety by relieving drainage and flooding issues in the Curtis Park and Five Points neighborhoods. The 27th Street Storm Drain project includes approximately 5,900 linear feet of large storm pipe ranging in size from 78 inches to 96 inches in diameter.
Construction is expected to begin on Phase 1 in late 2018.
Denver Public works is installing a new sanitary sewer line in the Golden Triangle neighborhood. This project adds capacity to the sewer system in the area and in particular relieves the existing 12" sanitary sewer in the alley north of W. 12th Avenue between Bannock and Cherokee Streets.
Construction began in early 2019 and concluded in June 2019.
Denver is installing a new storm sewer system in the Curtis Park neighborhood to provide 5-year storm protection to residents and businesses in the area and important drainage improvement around RTD’s East Rail Line. Five Points, Whittier, and City Park West neighborhoods are also situated in these drainage basins.
Storm drain construction starts at the South Platte River progressing uphill in 33rd Street, crossing the Downing Street intersection and continuing upstream in Martin Luther King Boulevard from Downing Street to Lafayette Street.
Construction is scheduled in several phases. The first several phases have been completed. Phase 4 is expected to begin in late 2018.
The City and County of Denver is making improvements to the existing 38th & Holly Detention Pond. During small and larger storm events, water collects in Holly Street at depths up to approximately 1.5 feet. The water then overtops the pond embankment along Holly Street to enter the pond and causes severe erosion to the embankment, creating on-going maintenance concerns and repairs.
The project will construct a new rundown to prevent future erosion, provide stormwater quality, and significantly re-landscape the detention pond and plant trees for pedestrian shade. When the improvements are complete, the project will safely direct stormwater into the detention pond while improving the water quality and the aesthetics for the surrounding neighborhood.
Construction is beginning in Fall 2018.
This project is the construction of a new storm drain at the intersection of 43rd Avenue and Sherman Street in the Globeville neighborhood. This intersection has long been prone to ponding and flooding and has received numerous neighborhood complaints. The new storm pipe will be built in Sherman Street and connect to an existing undersized storm system at 44th Avenue and Sherman Street.
Construction began in Spring 2019 and is expected to continue through Summer 2019.
The East 16th Avenue Storm Interceptor project area is located in Montclair Basin, to address flooding of the neighborhood. Existing storm sewers in East 16th Avenue and Batavia Place are currently undersized; this project's goal is to work with hydrology developed by the Outfall Systems Plan (OSP) team to size, design, and construct a new storm main line to safely transport the flows from existing systems in Colfax Avenue and East 16th Avenue towards City Park, while picking up the local flows along the way.
Plan development is expected to be complete in late 2019, with construction to be determined following the final design.
The Ellsworth Avenue Storm Project is a key project identified in the City & County of Denver Storm Drainage Master Plan to relieve historic drainage problems in the Cherry Creek East neighborhood and reduce flows into the Cherry Creek business district. This project’s goal is to collect flows at low-lying intersections located between Garfield Street and Steele Street which currently flood both in summer and winter months and are prone to excessive ice accumulation.
In addition, the City and County of Denver is looking at implementing Green Infrastructure in this location as a part of its City-wide strategy for improving stormwater quality.
The Exposition and Fillmore Storm Drain will reduce localized flooding problems in the Bonnie Brae neighborhood. Denver’s 2014 Storm Drainage Master Plan identified the need for a storm drain at this location due to the significant amount of storm water that flows on neighborhood streets before entering the existing storm system in Exposition Avenue.
Construction is scheduled to begin in summer 2019 and last approximately 7 months.
The Jackson Street Storm Drain Project provides a critical link between the lower and upper Montclair Basin system for managing stormwater and offers improved flood protection for residents and businesses in the project area between Colfax and 12th Avenues, from Jackson to Albion Streets.
Denver Public Works is designing an improved and expanded storm drain system that will be constructed from Colfax Avenue and Jackson Street near National Jewish Hospital, and eventually tie into the existing storm drain system at 12th Avenue and Hale Parkway on the east side of Colorado Boulevard. This section of expanded stormwater pipes is essential in providing improved flood protection to the project area.
Denver Public Works and Denver Parks & Recreation are improving water quality and constructing a new playground at La Lomita Park, formerly known as Asbury and Tejon Park. This project will remove that concrete channel and relocate it to the edge of the park where it will be rebuilt as a naturalized, vegetated water quality channel that could include play features and educational components for nearby schools. In addition, a recreation lawn and playground will be rebuilt to be more functional for residents and community members.
Construction is expected to begin in June 2019 and conclude in Spring 2020. The park will be closed to visitors during construction to ensure safety for all.
The City and County of Denver, with Urban Drainage and Flood Control District (UDFCD) and Jefferson County, are making improvements to Marston Lake North Drainageway between South Garrison Street and Stanford Avenue and Balsam Park.
The project, located within Jefferson County and the City and County of Denver, will improve water quality and infrastructure at Stanford and Balsam Park, and develop a sustainable urban design that will result in structures being removed from the regulatory 100-year floodplain designation.
Denver Public Works and Flatiron Constructors has completed work on the Park Hill Storm Phase V project on Dahlia Street between 48th Avenue and up to Smith Road (before the railroad tracks). This project continued the Phase IV project finished in 2014, with the goal of reducing localized flooding problems and damage to roadways and private property.
The Sanderson Gulch stormwater project will improve the currently undersized drainage system between Lipan Street and the South Platte River. Construction of the new, higher-capacity drainage system will consist of underground, large-capacity stormwater box culverts (large pipes) to manage high-water flows during large storm events. The culvert system will be 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 begain in February 2018.
The City and County of Denver and the Urban Drainage and Flood Control District (UDFCD) are conducting an Outfall System Plan Study of stormwater management in the Montclair watershed. The Montclair drainage basin is over 9 square miles and is divided into the lower portion downstream of Ferril Lake in City Park, and the upper portion upstream of City Park. The current stormwater drainage system needs to be improved in some key areas. The Montclair Basin has been identified as a priority basin for storm drainage improvements and water quality improvement.
The City and County of Denver is working to establish a future vision for the Alameda Underpass near the Baker, Valverde and Athmar Park neighborhoods and the Alameda transit station. We will be looking at ways to improve movement for bicycles, pedestrians, transit, and vehicles.

The City and County of Denver will provide pedestrians and bicyclists with a safe, comfortable, intuitive connection underneath the railroad tracks heading east to the South Platte River Trail.
The fully funded project will remove the stairs to create an ADA accessible, separated path. This new ADA compliant facility will eliminate the gap along the D18 bike route providing increased safety, clearer wayfinding, and an improved user experience. The project will also include improved crossings at Santa Fe Drive and a new sidewalk offset from Santa Fe Drive, spanning Jewell Avenue to Florida Avenue.
The I-25 & Belleview Avenue Interchange Improvement Study is examining several possible improvements for the interchange of the South I-25 Corridor and Belleview Avenue between Monaco Street and DTC Boulevard.
The Belleview Avenue Corridor Study, completed in 2016, identified several alternatives for reconstruction, and ultimately chose one as the recommended alternative. The next and current step is a full assessment of the environmental impacts, required by the National Environmental Policy Act (NEPA), and further refined/detailed screening of alternatives from the Corridor Study.
The City and County of Denver is a partner in this study with CDOT, SPIMD, City of Greenwood Village, and Arapahoe County.
This project will involve a 1.1 mile extension of Martin Luther King Jr. Boulevard (MLK) from Havana Street east to Peoria Street within the Stapleton Redevelopment Area. The new roadway will include travel and parking lane changes, multi-use paths for bicycles and pedestrians, a soft-surface equestrian trail, and new signals and street lighting.
Construction is scheduled to begin November 19, 2018 and will continue until November 2019.
As part of the Elevate Denver Bond Program, which voters approved to fund critical improvements to infrastructure, Denver Public Works has begun the first phase of maintenance to a 25-year-old bridge over Park Avenue West to preserve and extend the life of the bridge.
Beginning in April 2019, crews will be performing repairs on the bearing pads underneath the bridge. For the safety of the crews working underneath the bridge, various lane closures will be in place around the Park Avenue West/Delgany/Wewatta intersection through July.
Denver launched an environmental review process in September 2017 to assess the impacts of implementing improvements on Quebec Street between East 13th Avenue and East 26th Avenue to improve mobility and safety, reduce congestion and enhance multimodal connectivity.
As the project team continued its analysis and began exploring preliminary design options for the proposed improvements, it was determined that estimated costs to implement the recommendations are well beyond the $23M we have in available funding and no additional funding for the project has been identified at this time.
Given the funding shortfall, we are pausing our Environmental Assessment of the Quebec Street Multimodal Improvement Project at this time to develop options around next steps.
The City and County of Denver Public Works is working to identify, design, and develop pilot streetscape improvements for the Santa Fe Corridor between 8th Avenue and West Colfax Avenue. Santa Fe Drive is an important corridor within the Denver transportation network. It is a key link between downtown, 6th and 8th Avenues, and I-25, providing connections for a variety of users in the neighborhood and the greater community.
While the piloting of an enhanced streetscape is the primary focus of this design study, it is also an opportunity to evaluate the Santa Fe corridor for a longer-term vision.
The City and County of Denver's planned improvements along South Broadway corridor and at the I-25 Interchange aim to create a corridor that provides safe and efficient mobility for all transportation modes (pedestrian, bicycle, transit, and automobile); promote transit-oriented development; and to accommodate the existing, future and planned developments along the South Broadway corridor.
Washington Street was identified in the Globeville Neighborhood Plan as “an attractive corridor that creates a positive sense of place, attracts private reinvestment, and better accommodates all transportation modes.” The Washington Street Study will refine and progress this vision of Washington Street into an implementable conceptual design.
The Walnut Street Corridor Improvement project, headed by Denver Public Works and the North Denver Cornerstone Collaborative (NDCC) will begin to organize the street to better accommodate pedestrians and parking between Broadway and 36th Street.
Phase I improvements were completed in Summer 2017. The city is now beginning a study of the entire roadway to determine long-term needs along this changing corridor.
In Phase II, the city will launch a full study of traffic conditions to determine the complete needs for Walnut Street along this stretch, including a possible two-way conversion. We will consider residential and commercial demand on the roadway as well as future development.
This project on West 32nd Avenue is focused on improving pedestrian safety along the corridor. Intersections at Irving, Julian, Perry and Tennyson will be redesigned in 2019 to improve the pedestrian environment with upgraded crossings and new infrastructure.
