What are the key project benefits for Eastside communities and the environment?
- New lids at Evergreen Point Road, 84th Avenue NE, 92nd Avenue NE and a landscaped overcrossing at Bellevue Way.
We will build landscaped sections over the roadway to help reconnect communities divided by the original construction of SR 520 in the 1960s.
- Noise reduction techniques.
We will build walls along the roadway between Evergreen Point Road and the vicinity of 108th Avenue Northeast to help reduce noise from highway traffic and provide screening for residents living along the corridor.
- Stormwater treatment and detention facilities between Evergreen Point Road and 108th Avenue NE.
We will improve water quality by treating stormwater before it enters local streams and creeks.
- Fish habitat improvements.
We will make improvements to Yarrow Creek and other streams and install larger culverts under the roadway that will decrease barriers to fish migration patterns.

There are six milestones in this review process:
1. Conduct public and agency scoping. During the public and agency scoping phase, we asked for comments from the public, tribal nations, and federal, state and local agencies on the purpose and need for the project and the environmental topics that we will evaluate during development of the project’s environmental assessment (EA). We held a public scoping meeting in September 2008.
2. Collect data and evaluate effects. The next step was to collect data on the existing conditions of the project area. This included conducting social, cultural, environmental and engineering studies related to the proposed project.
3. Issue environmental assessment. Following data collection, we prepared and published an EA in December 2009 that includes the results of our analysis and identifies ways we can mitigate the environmental effects of the project.
4. Public hearing and comment period. In December 2009, we held a public hearing to gather comments on the results of our evaluation and proposed mitigation measures.
5. Issue Finding of No Significant Impact. In May 2010, we published the Finding of No Significant Impact (FONSI) document, which concluded the environmental process. The FONSI explains the reasons for the project decision and includes the mitigation measures that have been incorporated into the project.
6. Secure permits and implement the project.
