Stream restoration and sewer pipe repair go hand-in-hand.
Construction began last week on a new restoration project in Johnson Creek!
The Luther Road Habitat Restoration Project will repair a 76-inch sanitary sewer pipe and manhole in Johnson Creek that are exposed due to erosion and are at risk of failure. The project also includes moving and restoring the channel of Johnson Creek and restoring natural floodplain functions.
This will help protect the sewer infrastructure, protect nearby private property and public health, and improve water quality and stream habitat for endangered salmon, trout and other sensitive species.
The picture above shows the exposed pipe and unstable, erroding stream bank.
The project site (shown at right) is on a 10-acre parcel along Johnson Creek near the intersection of SE Luther Road and the Springwater Corridor Trail.
The property was purchased by Environmental Services, North Clackamas Parks and Recreation District (NCPRD), and Metro. NCPRD plans to develop a park at the site in the future, and will protect the 6-acre restoration project as a natural area.
The project includes:
- 2,000 feet of new stream channel and 5 acres of new floodplain
- Sewer pipe will be reinforced and buried in place, eliminating a significant public health threat
- 6 acres of improved stream and upland habitat for fish and wildlife
- 3,000 feet of new trails with interpretive signs
- Over 13,000 new native trees and shrubs
The Luther Road project is part of Environmental Services and partners’ ongoing work to improve floodplain and stream functions, water quality and habitat in the Johnson Creek Watershed. A similar project was completed in 2006 at Tideman Johnson Park (see the update on that project here).
CONSTRUCTION ALERT FOR SPRINGWATER CORRIDOR TRAIL: During construction, vehicles will access the site from SE Luther Road at SE 73rd Avenue and across the Springwater Corridor Trail. About one construction vehicle will cross the trail onto the site every ten minutes. If needed, a flagger will direct traffic at the crossing point. Trail users will not be stopped unless it is necessary for their safety. Signs placed on the trail in advance of the crossing will alert users of the construction and possible delays.
