Council selects Alternative 4 as the Preferred Alternative in the BLUMA EIS
On December 14, 2021, the Sammamish City Council approved Resolution R2021-930, selecting Alternative 4 as the Preferred Alternative in the Balanced Land Use and Mobility Analysis (BLUMA) EIS. Alternative 4 evaluates a level of service standard (LOS) of the volume to capacity ratio (V/C) 1.4 for roadway segments and 1.1 for roadway corridors as well as land use measures to reduce overall travel demand and an assumed 15% reduction in AM and PM peak hour travel demand. Alternative 4 also includes a set of transportation capacity improvements intended to improve connectivity and efficiency in the transportation network by focusing capacity improvements on the principal arterials.
In addition to selecting Alternative 4 as the Preferred Alternative, Council directed staff to add a mechanism to reduce traffic counts based on any transit that is planned or purchased, to assess the project at any point at the choke points, and to assess mitigations or improvements around the schools.
The Preferred Alternative will be further evaluated in the FEIS, which is anticipated to be issued by the SEPA Responsible Official, pursuant to WAC 197-11-460 and SMC 20.15.060(7) in late March, 2022. The FEIS includes responses to comments submitted by the public on the Draft EIS (DEIS).
