Project Title & Location
SR 160 - SR 16 to Long Lake Road

Project Description
This safety improvement project flattens slopes from SR 16 to Phillips Road vicinity and increases road shoulder widths to 4 feet (6 feet between Estonia and Brasch). A two-way left-turn lane will be added from Fred Meyer to Brasch and left turn lanes will be added at Phillips Road. The project also creates flat bottom ditches for storage of treatment for runoff.

Design Construction Impacts
Right of way is proceeding early due to the large number of parcels affected by this project and the rising costs of real estate. The hydraulic report was nearly completed last year. However, new requirements and some changes to the design will necessitate a new hydraulic report. This report will be completed by the end of this year. Coordination is continuing with the utility companies, especially Puget Sound Energy, on relocation of the utilities affected by the project. Recent approval of the transportation budget by the Governor will allow this project to proceed as planned.
Local private development has had some impact on this project recently. It is anticipated that additional private development will also occur within the project limits between now and the scheduled advertisement date. Design changes will be required to accommodate these developments.

Environmental Impacts / Compliance
As designed, this project has minimal environmental impacts. Recent changes in definitions and regulations resulted in a new impact assessment. It has been found that no wetlands will be directly affected by this project. Additional investigation and possible mitigation, prior to advertisement, may be necessary to comply with possible future changes in the laws and regulations.

Impacts to Traffic
When construction begins some lane restrictions are anticipated during the widening and slope-flattening stages. Intermittent, one-lane alternating traffic is also expected through this phase. Single-lane alternating traffic will occur for two weeks during paving.
