20 MPH Local Speed Limit Reduction

The City and County of Denver has updated Denver’s default speed limit from 25mph to 20mph. This change applies to Denver's local streets — primarily the roads with no stripes that go through residential blocks. Additionally, wherever speed limit signs are not posted, the default speed limit will be 20 mph, per city ordinance.

Lowering the speed limit on local streets is part of a broader effort Denver is taking to address safety on our streets citywide. In 2017, the City and County of Denver set an ambitious goal of zero traffic-related deaths and serious injuries by 2030. Since then, Denver made significant investments in infrastructure to make city streets safer for all - especially our most vulnerable road users. By reducing the speed limit on our local streets, we can draw attention to the topic of vehicle speeds and help create a culture of safety within our neighborhoods where we are more likely to see people walking and biking.

West Colfax Pedestrian Crossing and Transit Improvements Project

The West Colfax Pedestrian Safety and Transit Improvements Project will construct roadway modifications between Sheridan and Irving Streets to improve the overall safety of the corridor for pedestrians. Additionally, the project will construct improvements that benefit the speed and reliability of transit service on the corridor. 

West Colfax Avenue was identified as a part of the high-injury network in the Vision Zero Action Plan. The high-injury network contains corridors with the highest percentage or serious injuries or fatal crashes. The pedestrian safety improvements are aimed to reduce crashes on the corridor and improve safety.

In 2017, Denver voters approved of funds in the Elevate Denver Bond to be used for pedestrian crossing improvements to West Colfax, as well as improving the efficiency and reliability of transit along the corridor. Transit improvements may include modifications to traffic signals and bus stops to support transit operations. Examples of pedestrian crossing improvements could include medians, curb extensions, and enhanced crossings that improve safety at intersections.

Bowles Ditch Storm Improvements

Olsson was retained by Mile High Flood District (MHFD) and the City and County of Denver to provide design of storm drain system improvements in the Marston Lake North Drainageway. The main objectives of the project are to separate stormwater flows from the Bowles Lateral, improve drainage and alleviate high ground water near the properties adjacent to the Bowles Lateral at Saratoga Place, and improve the overall drainage and reduce street flow through the project area.

The general design concept is to install new storm drain infrastructure to collect and convey 100-year flows from West Wagon Trail and South Field Way to the existing storm drain system downstream of the Glenbrook Pond. Storm flows will be separated from the Bowles Lateral with the improvements. The project will be completed in two phases.

Phase I construction began in December 2022 and was completed on June 30, 2023. 

Phase I consisted of improvements from the Glenbrook Pond outfall to just upstream of the Bowles Lateral. Storm drain lines, inlets, and manholes were installed in West Garrison Street and South Garland Street, then across the Bowles Lateral to West Saratoga Place. As part of the project Bowles Lateral was put into a 60-inch pipe. A headwall and wingwalls were constructed at the culvert entrance. An 8-inch French drain was installed along the new Bowles Lateral pipe in the vicinity of the ditch to collect groundwater. Curb Ramps were replaced at the intersections of South Garrison Street and South Holland Way, South Garland Street and West Garrison Street, and West Saratoga Place and where Wagon Creek Trail crosses West Saratoga Place. On West Garland Street, curb, gutter, and sidewalk were be replaced.

Construction for Phase II is planned to begin in 2024, and will last approximately 5 months.

Phase II includes installing improvements upstream of the Bowles Lateral, and at Hoyt Street and West Saratoga Place. Phase II includes installing 36- and 42-inch storm drain trunk line with laterals and inlets along West Saratoga Place, West Wagon Trail Drive, and South Field Way. The existing storm drain system in South Field Way will be connected to the new system at the intersection of South Field Way and West Wagon Trail Drive. Construction will also include curb ramps, curb, gutter, and sidewalk replacement. Additionally, inlets, laterals, and storm drain trunk line will be installed, conveying storm flows to the existing system in Hoyt Street, ultimately conveying flows to the Glenbrook Pond.

Upper Sanderson Gulch Storm Drain

The Mar Lee residential neighborhood was constructed primarily in the mid to late 1950s. Consistent with development at that time, there are no underground stormwater pipes in this project area. Therefore, stormwater runoff is currently served only with curbs, gutters and roadway cross-pans. Multiple stormwater studies have indicated the potential for excessive stormwater in the streets as well as flooding during heavy storms.  

The City and County of Denver and AECOM will proactively coordinate with residents and stakeholders to design a storm drain system that, once constructed, will improve greater protection from flooding with as little disruption to the community as possible. Design of the system was completed in 2022. Funding for construction is expected to be in place within the next five years.   

Localized, individual outreach as well as public meetings will be held as appropriate to identify community issues related to storm drainage design and impact.  

The Project Team is evaluating the design of a system of stormwater pipes that would run from Sheridan Boulevard eastward down W. Oregon Place and south on S. Xavier Street to Sanderson Gulch, and a second system starting at the intersection of W. Mexico Avenue and S. Wolcott Court, heading east on W. Mexico Avenue to S. Vrain Street and then connecting into Sanderson Gulch.

Wastewater Lining

The City and County of Denver is working to improve and rehabilitate storm and sanitary (wastewater) mainlines citywide. Wastewater mainlines are usually located in streets or alleys. Some of these systems are more than 100 years old.
