Springwater Wetlands and Floodplain Restoration Project

Updated October 22, 2019

Link to sign up for email updatesEnvironmental Services is starting a project to restore wetlands on about 60 acres in the Johnson Creek floodplain. The project will reduce the risk of flooding to homes, businesses and streets. It will also enhance wetland habitat along the Springwater Corridor Trail and improve water quality in Johnson Creek.

Location

The project will take place in the wetlands and natural areas along the Springwater Corridor Trail from Beggars Tick Natural Area to Zenger Farm. The project is located on public property between SE 104th Avenue and 122nd Avenue, SE Harold Street and SE Foster Road.

Schedule

Project design began in Fall 2019. Construction is expected to begin in the summer of 2022 and take at least a year to complete.

Background

The Springwater Wetlands and Floodplain Restoration Project will be Environmental Services' third floodplain project east of the I-205 Freeway in the Lents and Powellhurst-Gilbert neighborhoods. The Brookside Wetlands Project was built in 1997. The Foster Floodplain Natural Area was completed in 2012. While those projects reduced local flooding and improved the health of Johnson Creek, more work is needed.

The Springwater Wetlands Project will restore publicly-owned property. No additional land is needed to complete the project. This project will hold more floodwater on public land to reduce flood risk to local homes and businesses. As part of the project, BES will update the National Flood Insurance Maps for the Johnson Creek floodplain in this area.

What will this project do?

  • Reduce how often homes, businesses, and streets flood in the project area
  • Enhance habitat for sensitive wildlife
  • Improve the water quality of Johnson Creek

How will this be done?

BES will make several changes in the wetlands to restore the natural areas and reduce flood risks. The project will:

  • Add places on public property where flood water can go when Johnson Creek is high
  • Install culverts under the Springwater Corridor Trail and between the wetlands
  • Remove non-native plants and replace them with native plants
  • Build trails for maintenance access and emergency response

What do you think?

This project will mean something different to each person in the neighborhood. We want to know your thoughts about the wetlands, Johnson Creek, the floodplain, and the Springwater Project. Share your suggestions, questions or concerns about the project. We’ll keep you posted about public events, what’s happening with the project, and how you can weigh in.
