Extending Stormwater Infrastructure to Laurie Ave.
The project will install a new 12-inch diameter stormwater main on 436 feet of Laurie Avenue south of Courtney Ave and 6 catch basins to reduce the frequency of flooding. Additionally, 300 feet of stormwater main on Courtney Avenue west of Laurie Avenue will be replaced with 12-inch diameter stormwater pipe.
The new stormwater main and catch basins are expected to reduce flooding and convey a 10-year storm event.
Expect delays on Laurie Ave and Courtney Ave during construction.

Convert the intersection to a single-lane roundabout, widen the travel lanes to 12 feet, and add sidewalks and bike lanes.
We will also replace the culvert at Boeckman Creek under the intersection at the north end, add a culvert under the west end and add stormwater facilities to treat water runoff.
Clackamas County will partner with Washington County, Clean Water Services and the City of Wilsonville since the intersection spans multiple jurisdictions.
