S Forest St Outfall


Denver Public Works will improve the South Forest Street Outfall in the Virginia Village neighborhood of southeast Denver to reduce flooding and protect the area upstream of Potenza Park. The neighborhood drainage project, part of the General Storm Capital Improvement Program, will increase the capacity of the existing storm sewer system to improve drainage and protect property during a 100-year flood event.

Project Features

  • New storm drain infrastructure at the intersection of E. Nebraska Way and S. Forest Street to direct stormwater runoff into the outfall at Cherry Creek
  • Rebuilding the existing outfall to add capacity and connect to the new storm system
  • Improvements at the south entrance to Potenza Park to reduce runoff and flooding on Mississippi Ave.
  • Additional new storm drain in Missouri Ave from S. Forest St. to Elm St.

Update — Week of May 28, 2018

The S Forest Street Outfall project is now complete!

Project Status: Complete

Construction in the project area began in August 2017 and is expected to continue through 2018. Planning for this general storm project started in 2012, with design completed and approved in 2016. When completed, this project will relieve the surrounding storm sewer system, improving drainage capacity and reducing the risk of flooding.

Construction was completed at the end of May 2018.

Thanks to everyone who attended the public meeting with Councilman Kashmann on August 23.


Construction Information

The northwest portion of Potenza Park will be closed and fenced during work as a precaution to protect the public and workers. Construction is expected to begin in late summer 2017 and continue for approximately a year.

Denver Public Works has been coordinating with Denver Parks & Recreation on this project, analyzing pipe routes that would minimize the impacts to trees and the park. The park will fully reopen after construction. 

In May 2017, crews surveying the work area at Potenza Park found asbestos in old construction debris. Denver Environmental Health worked with Public Works, and Parks & Recreation to identify the debris that contained asbestos materials, which will be removed with installation of the new storm sewer.

The contractors have modified the original work plan for safe removal of the excavated materials, and crews will remove all construction debris, even materials where asbestos was not present. The remeditation process also required the removal of additional trees.

Denver Environmental Health is committed to protecting public and environmental health during this process. Contact Denver Environmental Health for additional information.

Trees will be removed as a part of the project. Originally 9 trees were to be removed; since asbestos was identified additional tree removals were required resulting in a total of 20 trees removed. Denver Public Works will compensate the City’s Forestry Division for the trees that are removed.

Denver Parks & Recreation will work with the community on the future planting plan for Potenza Park.

The city encourages all residents to be aware of flood risks and take precautions to protect their lives and property. Learn more at to understand your flood risk and get information on what you need to do to stay safe.
