Indian Creek

Indianriver washington

Overview

Location: New Port, Washington

Project Type: MSE Wall

Application: Highway Embankment

Product Used: PYRAWALL®

Problem

Pend Oreille County needed to remove a culvert on Indian Creek that was preventing Bull Trout, a threatened species, from traveling upstream to spawn. Additionally, the county needed to realign the road to address its aging condition and residents wanted a solution with a natural, vegetated look rather than a concrete wall along the wetland.

Solution

The culvert was replaced with a 58-foot, single-span bridge. Limited physical and right-of-way access dictated that steep wing-walls would be needed for the earth-fill embankment approaches. Steel sheet pile would exceed the budge, and vinyl sheet pile didn't meet the strength criteria. PYRAWALL® was selected because it is an engineered wrap-face, vegetated solution that costs less than a concrete retaining wall.

Performance

PYRAWALL was used to build a more economical 210 feet long and 14 feet tall east-approach embankment, and the 340 feet long and 18 feet tall west-approach embankment.
