East 16th Avenue Storm Interceptor

Upcoming Bike Lane Work Near This Project

A different contractor will soon start work on a lighted bike crossing of 17th Ave. at Garfield, just west of our project area. The new crossing will connect to an existing bike path in City Park. There will be some impacts to Garfield associated with this work. All questions or concerns regarding this work should be sent to Jacob Hurley at jacob@circuitmedia.com / (515) 451-7494.


This project is increasing the size of stormwater pipes that run east/west under Colorado Boulevard to increase the amount of stormwater we can collect and carry. The first phase of this project requires us to close East 17th Avenue, just west of Colorado, through March 2022 as we open up the existing roadway surface and install bigger storm pipes underground. Before the end of 2021, we will continue east, installing new pipes underneath Colorado Blvd, and will start work along 17th Ave Parkway, east of Colorado Boulevard. We encourage you to stay informed about this project and sign up for regular project updates by emailing info@16thavestorm.com.

This project marks the continuation of a backbone system we are building to ultimately reach and provide relief to well-known, documented flood areas that include 14th and Krameria, 14th and Kearney, and 16th and Dahlia.

We ask for your patience as we make these critical safety improvements and hope you will recognize the significant investments the city is making in these areas of town most at risk for flooding.  We know it can be frustrating when travel is impacted.


Full Closure of 17th Avenue

Closure Information

17th Avenue is fully closed from Jackson Street to Colorado Boulevard until March 2022. Detour signs are posted and message boards were placed in advance of the closure.

Closure Information: Closure 002 is expected to begin in January 2022.

This goal of this project is to work with hydrology developed by the Outfall Systems Plan team to size, design, and construct a new storm main line to improve safety and reduce flood risks in the South Park Hill neighborhood, safely transporting the flows from existing systems in Colfax Avenue and East 16th Avenue towards City Park, while picking up the local flows along the way.

The existing storm sewers in E. 16th Ave. and Batavia Pl. are currently undersized to adequately convey stormwater levels, resulting in frequent and significant flooding in the South Park Hill neighborhood. The construction includes installing a new stormwater pipe beneath Colorado Boulevard which will connect to the current the stormwater system at City Park Golf Course.

In addition to the storm pipe construction, work includes roadway reconfiguration and traffic signal changes at the intersection of E. 17th Ave. and Colorado Blvd., as well as safer crossings for pedestrians and cyclists.

Work begins at Jackson Street and E. 17th Avenue, continues east along E. 17th Avenue Parkway, crosses Colorado Blvd and turns south onto Albion Street for approximately 100 feet.

Construction Methods, Impacts and Delays

We are actively monitoring how people in cars flow through this part of town to reduce cut-through traffic on residential streets off East 17th Avenue. We have implemented additional traffic control measures that narrow 17th Avenue on its approach to York and Josephine and encourage only local traffic to continue on 17th Ave past York and Josephine. Please note this change will result in the loss of the RTD Route 20 Bus Stop at York/Josephine and we’ll be restricting right turns from northbound Josephine onto eastbound 17th Ave.

We do anticipate increased traffic flow on East Colfax Avenue, East 23rd Avenue and other east/west routes as 17th Avenue is closed for our project. This full closure will be in place until March 2022. Please refer to the map above. 


Traffic Impacts

Various street closures will be in place on 17thAvenue, Colorado Boulevard and 17th Avenue Parkway when crews are scheduled to work on those stretches. Residences immediately adjacent to the construction site will receive advance notice before work begins on their block. Walk-up access to residents and businesses inside the project area will always be open.

Detour signs and message boards will also be in place throughout the duration of the project to alert commuters about the work and to expect delays. All work is weather dependent and subject to change. Signage will clearly define and direct the detour routes, and we will be sending out weekly impact / detour maps in our email updates — so be sure to sign up for these crucial emails.

The public’s patience and cooperation during construction are greatly appreciated.

May 21, 2021

Status: Crews are mobilizing on the site and you will start to see lots of heavy equipment moving in. The full closure of 17th Avenue—from the alley west of Jackson Street to Colorado Boulevard—is now into effect. Message boards with street closure information, and signage showing the suggested detour routes are in place.
 
Impacts: This first closure will be in place between 4-6 months. Please use the suggested detour routes. Next week, there will be uniformed traffic officers at 16th Colorado and 17th Esplanade to make sure non-local traffic flows around the neighborhoods, rather than through. If you live and/or work in these areas, please talk to the officers — they have been directed to allow local residents / employees / deliveries access. Over the weekend, the detours at 17th York and 17th Josephine will also be shifting to better handle traffic flows.

Water Main Work: There are some upcoming water service shutoffs — if you are affected by these shutoffs, you will be informed a minimum of 24 hours in advance by the contractor.
 
Nearby Projects: There is work being done on nearby projects by Q3 and PSC so you will see their trucks and resulting closures in the neighborhood. Those projects are not affiliated with this project.

Construction Fencing: Please do not move the fencing surrounding the work for any reason—it is in place for the safety of all. Violations will be reported to the proper authorities. 

Safety First: Please be cautious when walking / driving / biking near the project, and please do not enter the site for any reason, or follow construction vehicles onto the site.

Rider Alert / RTD Route 20 Changes: Due to the construction, there will be some changes to RTD’s route 20. Please visit the RTD website for details. https://www.rtd-denver.com/app/alerts/routes/20
 
Reach Out: If you have any questions or concerns it’s easy to reach us. Just send us an email, call or text the hotline, or call me directly. All of our contact information is listed in the box below. 
 
Thanks for your patience as we get this project rolling.

We hear your concerns regarding traffic issues as a result of the detours and closures. We are adding to our traffic control devices and reworking some detours on a daily basis. We are experiencing a lot of comments at this time, but we continue to monitor and address the traffic control as necessary, and will keep you in the loop with updates.

Please note: Q3 has a closure on Harrison that is not associated with this project. And please do not relocate existing traffic control devices as it is illegal.
