E. Yale Avenue Storm Drain


The East Yale Avenue Storm Drain project addresses frequent flooding in the University Hills neighborhood in southeast Denver, at the geographic low point in S. Glencoe Street south of E. Yale Avenue. This location was identified as a Significant Flooding Location in the City’s Storm Drainage Master Plan. The first phase of the project is addressing storm drainage along Yale Ave. between Glencoe St. and Dahlia St, significantly improving the drainage conditions in this low-lying area during smaller, more frequent storm events. This new storm water infrastructure will provide capacity to drain approximately a 10‐year storm (a storm intensity level that has a 10 percent chance of occurring in any given year); a 100-year storm system (than can handle a storm with an intensity level that has a 1 percent chance of occurring in any given year) cannot currently be installed due to physical limitations in the E. Yale Avenue corridor.

In the future, additional phases of improvements (from Colorado Blvd. to Elm St.) could increase the level of storm water service in the low lying area to a 50-year storm system, depending on the proposed designs of future pipes. Upon completion of these later phases, flooding within the University Hills neighborhood will be significantly reduced, improving public safety during larger storm events

Construction Update: April 2018

During the week of April 23, Flatiron Construction will continue work on the stormwater project proceeding eastbound on E Yale Avenue.

Traffic impacts

  • East Yale Avenue: Beginning west of S. Dahlia Street, eastbound and westbound traffic on Yale will be pushed to the two far north lanes. The far south lane of eastbound Yale will remain open as far as Dahlia to allow vehicles to turn right onto Dahlia southbound.
  • S. Eudora Street: Right turn only onto Yale by vehicles traveling southbound on Eudora.
  • S. Elm Street: Access to Yale from Elm will be blocked, with traffic detoured to E. Cornell Avenue.
  • S. Fairfax Street: Right turn only onto Yale by vehicles traveling northbound on Fairfax. 
  • S. Glencoe Street will be closed to thru traffic between E. Yale Avenue and S. Grape Way while crews lower sanitary sewer service connections.

We anticipate completing the current phase of storm drain construction along E. Yale Avenue between S. Dahlia and S. Fairfax Streets the week of April 23, followed by street paving of this completed section during the week of April 30.

Traffic control will then be moved accordingly as the next phase of construction begins along E. Yale Avenue between S. Fairfax Street and S. Glencoe Street.

Project Status: Construction

Construction on this storm infrastructure project began at the intersection of E. Yale Avenue and S. Dahlia Street on February 5, 2018. Work is anticipated to last about one year, with 4 to 6 months of work on E. Yale Avenue before moving to S. Glencoe Street. When completed, this project will provide a 10-year storm drain system to relieve persistent flooding and adequately drain the surrounding neighborhood's low-lying area.

Denver Public Works began upgrades to the existing storm infrastructure in this area on February 5, 2018. The project is starting at the intersection of Yale Avenue and Dahlia Street and will continue east along Yale Avenue to S. Glencoe Street, and then head south on S. Glencoe Street to the intersection of S. Glencoe Street and S. Grape Way.

The entire project is anticipated to last about one year. The first half of the project (4-6 months) will be performed on Yale Avenue, with the second half of the work occurring on S. Glencoe Street to complete the project. The existing overhead utility lines on the south side of E. Yale Avenue were converted to underground lines prior to the start of construction.

While work is underway, Denver Public Works anticipates that one traffic lane will remain open in each direction on Yale Avenue, but drivers should expect delays. S. Glencoe Street and S. Grape Way will be closed to through traffic during construction, but will remain open to residents. 

In addition to this storm drainage project that will reduce flood impacts, Denver Public Works will also make improvements later in 2018 at the intersection of Yale Avenue and Dahlia Street, which includes enhancements to pedestrian ramps and the traffic signals.  

The East Yale Storm project is part of the Wastewater Capital Projects Management 6-Year Capital Improvements Program, but the 2017 GO Bond that was approved by voters in the November 2017 election will fund additional infrastructure projects on Yale Avenue. Beginning in 2018, funds will be available for design and construction of:

  • A High Line Canal bicycle and pedestrian tunnel at Yale Ave. and S. Holly Street
  • Improvements along Yale from I-25 and Quebec Blvd. to improve traffic flow
  • Pedestrian safety efforts at the RTD Yale Station
