US 12 - Naches River North of Yakima - Stabilize Slopes - Complete October 2008

Quarterly Project Report Update for Quarter Ending June 2008

Project Title & Location
US 12 - Naches River North of Yakima - Stabilize Slopes

Project Description
The area of US 12 along the Lower Naches River, near the 16th Avenue interchange, suffers from repetitive bank erosion and slope failures. Emergency work has been performed in this area four times since 1999. This project will correct this chronic environmental deficiency by moving the Naches River channel away from US 12, and construct a bio-engineered structure in the river to reduce future problems and protect the roadway and environment.

Contractor/Consultant
Scarsella Bros. Inc. of  Seattle Wa.

Recent Progress
Work started on June 16 at the beginning of inwater work window.

Design Construction Impacts

Environmental Impacts / Compliance
Field inspectors and region environmental staff will closely monitor construction and conduct water quality monitoring as needed

Impacts to Traffic
When work starts in June, US 12 westbound traffic will be restricted to one lane in the project area during work hours. Both westbound lanes will be open during non-work hours.

The project will also have a ramp closure / detour for traffic coming from Yakima on 16th Ave. going to westbound US 12. During ramp closures traffic will be detoured to North First St. in Yakima to get to westbound US 12.
