Holland Basin Stormwater Improvements
This project will use some of “The Basin” next to Edison High School to treat stormwater as it moves through the City, cleaning the water before it flows to the Mississippi River. The middle of the basin will be filled with native plants and the north and south ends of the basin will remain how they are now. When it rains, the planted area in the middle will fill with water.
Construction for the Holland Basin changes began on October 14, 2020.
Most of the initial construction during the first two weeks will be in the basin. Quincy Street NE between 20th and 22nd Avenue NE will be closed. This first phase of construction will include installing pipes and lowering the middle of the basin. Planting will occur in the spring of 2021.
The Holland Basin was built by the City of Minneapolis in the early 2000’s as a flood relief basin for Northeast Minneapolis, located east of Thomas Edison High School in the Edison Green Campus. “The Basin” was designed as a space for water to fill instead of flooding adjacent homes or the school buildings. It also provides open space for the Holland Neighborhood. More information and background can be found on the Holland Basin Fact Sheet.
What to expect
- Construction to retrofit “The Basin” to treat stormwater runoff (remove pollutants like sediment, heavy metals and nutrients such as phosphorus) from the neighborhood in addition to flood relief
- Most of the work will occur in the basin near the pedestrian bridge. Some construction will happen on Quincy Street NE and the cul-de-sac on 20th Avenue NE (west of Jackson Street NE). Resurfacing of the roads in these areas will be delayed until the construction is complete.
- Regrading and new pipes in the middle of the basin
- Native plants will help soak up the water and provide a habitat for birds and pollinators
- Removal of nearly 90% of sediment (TSS) from over 20 acres of land
- Large areas of the lawn will remain open at each end of the basin for those that enjoy using that open space
Construction impacts to area
Residential and school traffic may be affected on Quincy Street NE (between 22nd Ave NE and 19th Ave NE) and 20th Avenue NE (west of Jackson Street NE).
