Reducing Environmental Impacts• Fish Passage Design with Tribal Agencies

• Wetland Delineation

• Stream Delineation

• Marbled Murrelet & Spotted Owl Assessment

• Coordination between WSDOT, County, and different contractors (IMCO, Granite, Atkinson)

• Reducing Impacts to Wetlands with design refinement (2:1 Slopes, Roadway Alignment, Roadway Elevation)

Key Partners• FEMA• Snohomish County

• Public Works• Parks• Community Development

• Stillaguamish Tribe of Indians• Washington Dept. of Fish and

Wildlife• US Army Corps of Engineers• Washington State Ecology• Atkinson Construction• Jacobs

Reducing Community Impacts

• Local contractors and people hired from the surrounding community to work on the reconstruction and debris removal.

• Creation of on-site mitigation (instead of using proposed mitigation bank) reduced project costs, created open space for the County, and preserved high-quality wetlands.

• One-on-one coordination with adjacent property owners.

Environmental Successes/Design Build Innovations

• Collaboration focused on the community and environment allowed flexibility by the contractor, designer, and agencies as the project progressed

• Right-sizing culverts and the onsite wetland and stream mitigation site saved money, restored streams and wetlands, is a memorial to Linda McPherson, and was transferred to Snohomish County Parks as a protected natural area

• Extraordinary construction water quality management by Atkinson

• Reuse of excavated soil on Snohomish County’s White Horse Trail reconstruction

• Contractors shared security costs

Successful Project Outcomes• Completed reconstruction of SR 530 in just 6

months after the landslide — construction lasted only 13 weeks.

• Opened two-way temporary road within days of contract award.

• Coordinated, designed, and constructed six fish passage culverts.

• Designed and restored wetlands at two staging areas.

• Designed, permitted, and constructed the Linda Lee McPherson wetland and stream mitigation site on 36.3 acres.

• Saved WSDOT $5.4 million over the engineer’s estimate.

McPherson Mitigation Site“The goal of putting a high price tag on the use of the existing mitigation site was to incentivize the DB to minimize impacts to aquatic resources but it had an unexpected—but extraordinary—result. The DB decided that it was a better value to purchase and develop their own mitigation site, McPherson. This is unprecedented in my experience with the agency and it resulted in the acquisition and protection of a really high quality property in the immediate impact area, the McPherson site.”

-Linda Cooley, WSDOT Environmental

Tips to share

• Start planning now• Bringing your A Team• Assign areas of responsibility • Have extra people on hand• Start tracking – daily logs, dollars expended, labor

hours.• Communicate, Communicate, Communicate• Use internal and external resources• Recognize and tend to emotions • Give grace to people
