Springwater Wetlands and Floodplain Restoration Project

Sewer and Stormwater
Environmental Services is designing a project to enhance wetlands on about 30 acres along the Springwater Corridor Trail. The project will reduce the risk of flooding to homes, businesses and streets.
Design for the project began in Fall 2019. Construction is expected to begin in the Spring of 2024 and will take about a year and a half to complete.

What’s Happening Now?  

Starting January 2024, crews will be on site to resume the removal of trees. Tree removal work is in preparation for upcoming construction work to restore the natural floodplain.

Week of January 8 - Nuisance Tree Removal

Tree removal services will occur during daytime hours between 7 a.m. and 3 p.m. at the following location: 

  • SE 115th Avenue and SE Ramona Court –Contractors will restart tree removal on and near properties in this area. English hawthorns, laurels, and many other trees on the Nuisance Tree List will be removed. These activities help to reduce nesting habitats prior to upcoming construction. The City Forester has reviewed and approved the project’s tree removal plan. 

All work is weather-dependent and subject to change due to contractor availability.

This work will temporarily restrict some travel lanes and sidewalk crossings in work zones, remove on-street parking, and may create traffic delays. 

Please obey all traffic control signs and follow the directions of flaggers.

Project 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 Project will restore publicly owned property. 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.
