Springwater Wetlands and Floodplain Restoration Project

Sewer and Stormwater
Environmental Services is designing a project to enhance wetlands on about 70 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 2025 and will take up to a year and a half to complete.

What’s Happening Now?  

Project designers have reached the 60% design milestone. Project design is focused on reducing the risk of flooding to homes, businesses, and streets. In addition, the project aims to improve water quality, provide improved pedestrian and bicycling routes, and restore healthy habitats for wildlife: birds, pollinators, protected red-legged frogs, as well as other amphibians.   

Site Preparation and Deconstruction Activities Occurring Soon 

Recently, Environmental Services purchased the property at 5809 SE 117th Street.  This property will be included in the Springwater Wetlands Project as part of the habitat restoration area. In preparation for habitat restoration work, the structures on the site will be deconstructed and recycled. 

Deconstruction work at the property site is expected to begin the week of January 30 and should take four to six weeks to complete. Please note – site protection fencing around the property will remain in place after the deconstruction to ensure continued work zone safety.  

Rest of this Week  

Before deconstruction begins, crews will be on site to and prepare. Activities may include site visits and evaluation, surveying, marking and relocating utilities, taking pre-existing conditions photos, and tree trimming and protection. To learn more about these activities, please visit the preconstruction information website

Week of January 30  

Work will occur during daytime hours between 7 a.m. and 6 p.m. 

  • Install temporary traffic control signs according to approved traffic control plans. 
  • Install temporary on-street parking removal areas and site fencing to secure safety of the work zone. 
  • Post signs and fliers to notify all residents, pedestrians, and motorists of upcoming deconstruction. 
  • Begin deconstruction and removal of outbuildings. 
Week of February 6

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 Springwater Wetlands 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.
