The Urban Drainage and Flood Control District (UDFCD), Jefferson County, and City and County of Denver have partnered with Jacobs Engineering Group (Jacobs) and ECI Site Construction Management, Inc. (ECI) to design and construct improvements to Marston Lake North Drainageway between South Garrison Street and Stanford Avenue and Balsam Park.
The proposed improvements are located within Jefferson County and the City and County of Denver. Nearby streets that bound the project are South Garrison Street to the west and Balsam Parkway to the east. Drainage within the project limits flows from west to east.
The project will remove the existing concrete forebays and trickle channels, existing outlet structure and pipes, and the current permanent pool. During construction, the grade in the detention pond will be modified to provide additional stormwater capacity and reduce the risk of stormwater flows spilling from the detention pond and drainageway.
Improvements will also enhance the recreational value of the detention pond:
Construction began in January 2019 and is expected to be complete in April 2020.
During construction, portions of the park, roadways, sidewalks, and trails in the area will be closed off at different times. At least one lane of traffic and one sidewalk will remain open on Garrison Street and Stanford Avenue.
