Madsen Creek's Tributary 0306A Pipe System Replacement at Fairwood Boulevard Southeast Project

Overview

Approximately 440-feet of pipe (consisting primarily of 24-inch and 48-inch-diameter pipes) and drainage structures (catch basins) will be replaced. It is anticipated that the pipe system will be replaced with larger pipes/culverts and an engineered stream channel that can provide fish passage along the existing stream corridor.

Other work at the site includes adjustments to the remaining pipe and catch basin system downstream of the new pipe system channel as well as planting a new riparian corridor along both sides of the new stream channel. The total project area just under an acre.

We are coordinating closely with the Fairwood Greens Homeowners’ Association, the Fairwood Country Club and Golf Course, the primary landowner and other stakeholders. The project requires multiple permits to ensure the project is following regulations and compatible with existing and projected land uses and plans.
