On this page, you’ll find information about major studies, planning efforts, and construction projects currently underway in Denver Public Works.
This pilot program is part of a larger city initiative to meet needs for publicly accessible restrooms in the central part of the City. In addition to mobile restroom facilities that can be moved to serve select activities and areas, the City is also reactivating existing facilities at parks and public sites.
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 City and County of Denver Infrastructure Project Management is working to improve and repair sanitary mainlines in the city's residential neighborhoods. The sanitary mainline is a large pipe where the water from residential appliances (dishwashers, washing machines, sinks, toilets, showers and bathtubs) flows after it leaves a home or business. The sanitary mainline is usually located in the street or alley adjacent to the property. Some of these systems are more than 100 years old.
The process uses a polymer resin lining to preserve the integrity of sanitary systems, preventing failures in older lines and minimizing any leakage into soil or waterways. This method is also less invasive to neighborhoods compared to open cut projects around the City. Each main can be lined in a single day, allowing crews to complete work on a street with minimal traffic or access impacts.
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 will be installing a new sanitary sewer line in the Golden Triangle neighborhood. This project will add capacity to the sewer system in the area and in particular relieve the existing overtaxed 12" sanitary sewer in the alley north of W. 12th Avenue between Bannock and Cherokee Streets.
Construction is scheduled to begin in early 2019 and is expected to last seven months.
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.
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 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 Flatiron Constructors will be conducting work on the Park Hill Storm Phase V project on Dahlia Street between 48th Avenue and up to Smith Road (before the railroad tracks) from October 2017 to October 2018. This project is the continuation of the Phase IV project completed 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 Brighton Boulevard Redevelopment Project will design and construct critical public infrastructure (e.g. cycle track, sidewalks, curb/gutter, on-street parking and more) on Brighton Boulevard, helping establish Brighton as a gateway to Denver.
Work on the first two segments, from 29th Street to 44th Street, began in Fall 2016 and will be substantially complete in 2019. Additional construction along the corridor will be planned in phases to the northern city limits.
The initial vision was developed in 2014, followed by a planning process with stakeholders to determine key elements for the design.
Colfax Corridor Connections is a project that is studying mobility needs and identifying transit and other multimodal improvements, including bicycle, pedestrian and vehicular, within the East Colfax travel corridor. The corridor is roughly bounded by I-25 and I-225 to the west and east, respectively, and by 12th Avenue and 20th Avenue on the south and north.
In September 2015, The City and County of Denver launched the Denver Moves Broadway/Lincoln Corridor Study to evaluate new concepts for moving more people, safely, along the corridor between Colfax and I-25.
The second phase of the study began in August 2016, with installation of a two-way protected bikeway on South Broadway from Bayaud to Virigina, to help Denver Public Works evaluate safe travel options for everyone along the corridor. The bikeway is part of a larger Broadway/Lincoln Corridor study that kicked off a year ago with a community-driven process that helped determine the bikeway’s placement.
Denver Moves: Downtown is a planning effort that is re-envisioning the city’s downtown transportation system. It will build off years of study and analysis to create a roadmap for implementing tangible near-term improvements that the hundreds of thousands of people who live, work, study, visit and play in downtown Denver will experience in the coming years, while also identifying a long-term vision for the future of mobility in the city’s center.
The effort is being led by the City and County of Denver, in collaboration with the Regional Transportation District and the Downtown Denver Partnership, and will be completed in early 2020.
Denver Public Works is preparing improvements to Federal Boulevard between West 5th Avenue and Howard Place to improve safety and operations for multimodal travel. Preliminary design began in 2011, following the vision established in the city's Federal Boulevard Corridor Plan in 1995 and a study of Federal Boulevard between 5th Avenue and Howard Place.
Roadway reconstruction between W 7th Ave and Holden Place is expected to begin in 2018; additional restriping is planned between 5th and 7th avenues and from Holden to Howard.
The project comprises the design and construction of a bicycle and pedestrian bridge with stairs and ramps crossing over the Union Pacific railroad line, south of the existing crossing at 47th Avenue and York Street. Design will conclude in 2018, with construction expected to take place in 2019.
This location was identified in the Elyria Swansea at York - East/West Connectivity Study conducted in 2016 to evaluate multi-modal connectivity in Elyria Swansea and improvements in the area north of I-70 and south of 49th Avenue.
Denver Public Works is planning improvements to 56th Avenue across the Peña Transportation Corridor, from Memphis Street east to approximately 400 feet east of the Regional Transportation District (RTD) A-Line rail bridge, to improve traffic operations and safety of the interchange, address future travel demand, and enhance multimodal use and connectivity.
Environmental should be completed late summer or early 2019, with final design completed in Spring 2019. Construction is expected to begin spring 2020.
The Hampden Avenue corridor is a critical east-west arterial near the southern limits of the City and County of Denver serving residents, visitors, shoppers, and employers. The vision for Hampden Avenue is to increase corridor connectivity and provide multimodal options that are safe and comfortable for all users, better reflecting the needs and desires of the community. The goal of the study is to identify improvements that can be implemented in the near- and long-term.
This project will provide a continuous multi-use trail bypassing the busy intersection of Hampden Avenue and Colorado Boulevard by building two underpasses beneath these two major arterials. This will improve the connection of the High Line Canal Trail in Denver and neighboring areas, creating a safer environment for pedestrians and cyclists.
A final design is expected to be completed by mid-2018. Construction would begin in 2018 or later.
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.
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'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.
