The City is preparing an environmental impact statement (EIS) pursuant to the State Environmental Policy Act (SEPA) to analyze growth and infrastructure needs throughout Sammamish. The goal, initially prompted by the GMHB Gerend decision, is to provide the City Council with tangible Growth Management Act (GMA)-compliant options that will result in the ability to more comprehensively address these issues in Sammamish.

Municipal Code amendments are also possible to implement amended Comprehensive Plan guidance and, if pursued, are anticipated to focus on Titles 14A and 21A SMC. Code amendments could, for example, amend Level of Service (LOS) standards to reflect amended Comprehensive Plan guidance, delete outdated tables, correct definitions and Comprehensive Plan references, and take other related actions. To ensure GMA compliance, the process will also consider the need for possible amendments in various Comprehensive Plan elements. Comprehensive Plan amendments could also include updated policy guidance and updated background information.

    CITY OF SAMMAMISH

    NOTICE OF AVAILABILITY OF A SEPA FINAL ENVIRONMENTAL IMPACT STATEMENT (EIS)

    BALANCED LAND USE AND MOBILITY ANALYSIS

    Final EIS Issued on March 31, 2022

    Notice is hereby given under WAC 197-11-460 and WAC 197-11-510 that the City of Sammamish has issued the Balanced Land Use and Mobility Analysis (BLUMA) Programmatic FINAL Environmental Impact Statement (Final EIS) addressing proposed Comprehensive Plan and Code Amendments.

    Description:

    Proposal: The proposal consists of amendments to the Sammamish Comprehensive Plan and Sammamish Municipal Code (SMC) necessary to amend and implement the City's transportation level of service (LOS) standards and concurrency management program. Amendments may include:

    • Amendments to the Transportation and Capital Facilities Elements, Volume I for transportation LOS standards. Amendments to Transportation and Capital Facilities Elements, Volume II, to update discussion of LOS standards and concurrency, the 6-Year Transportation Improvement Program (TIP), the traffic forecasting model, recommended long-term transportation project list, and financing information. Consistency amendments to other elements may also be required.
    • Potential changes could include but are not limited to the Sammamish Unified Development Code (SDC) Title 21, formerly known as Sammamish Municipal Code (SMC) Titles 14A, 20, 21A, and 21B, to update definitions, address internal consistency, and implement the amended transportation LOS standards in the concurrency management program, depending on the preferred alternative.

    The Final EIS completes the environmental review process for the proposal. The Final EIS studies a Preferred Alternative, selected by City Council on December 14, 2021 through Resolution R2021-930, and responds to all comments received during the Draft EIS process (published on August 26, 2021), describes the existing conditions and identifies probable significant environmental impacts, mitigation measures to mitigate these impacts, and any significant unavoidable adverse environmental impacts from the proposal, in accordance with RCW 43.21C.031.

    Environmental Topics: The topics studied under the Draft EIS include: earth, water resources, plants and animals, land use, housing, plans and policies, transportation, and utilities (i.e. broadband).

    Alternatives: The Final EIS evaluates a Preferred Alternative for each environmental topic that is in the range of the four alternatives that were analyzed in the Draft EIS, including a no action alternative. Alternatives studied in the EIS process include the following:

    • Alternative 1 - No Action Alternative is the continuation of transportation LOS standards and concurrency program requirements currently in effect.
    • Alternative 2 - Transportation Level of Service (LOS) Standards is the continuation of LOS standards for intersections and new LOS standards for key roadway corridors and segments. Also includes improvements to transportation infrastructure to meet new LOS standards.
    • Alternative 3 - Transportation LOS Standards with transportation-efficient land use measures is the same LOS standards for intersections and key roadway corridors and segments as Alternative 2 with an assumed 15% reduction in peak hour trips. Includes land use measures to reduce overall travel demand and improvements to transportation infrastructure to meet new LOS standards.
    • Preferred Alternative (Alternative 4) - Transportation LOS Standards with transportation-efficient land use measures and holistic transportation capacity improvements is the same LOS standards for intersections and key corridors and roadway segments as Alternative 2 with an assumed 15% reduction in peak hour trips. Includes the same land use measures as described in Alternative 3. Transportation capacity improvements intended to address transportation needs holistically, considering local and regional connectivity, improvements to substandard streets, transit and non-motorized needs, and environmental constraints. Also includes improvements to transportation infrastructure to meet new LOS standards.

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    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).

    Purpose

    On July 7, 2020 the City of Sammamish issued a SEPA Determination of Significance and Scoping Notice and request for comments pursuant to WAC 197-11-408. This is an optional revised scoping notice pursuant to WAC 197-11-408(4) provided for informational purposes because additional alternatives are being considered which expand the scope of the EIS.

    There is no additional comment period associated with this optional notification. However, the City of Sammamish values public participation and provides below information regarding how to get involved in this process.

    Description of proposal

    The proposal is a set of amendments to the Comprehensive Plan and Municipal Code intended to address transportation level of service standards and capital facilities needs and associated environmental impacts. Proposed amendments include (1) Comprehensive Plan amendments intended to adjust the City’s transportation Level of Service Standards (LOS) and related concurrency program, and (2) related Municipal Code amendments that implement amended Comprehensive Plan policy guidance.

    Comprehensive Plan amendments are anticipated to focus on the Transportation and Capital Facilities elements but may include additional elements as needed to achieve internal plan consistency. Comprehensive Plan amendments will include updated policy guidance for LOS standards and updated background information to reflect the City’s current transportation network, including maps and tables, concurrency program description, 6-Year Transportation Improvement Program, recommended 20-year transportation improvements, financing program, and other related information.

    Municipal Code amendments are anticipated to be focused on Titles 14A and 21A SMC. Municipal Code amendments will amend LOS standards to reflect amended Comprehensive Plan guidance, delete outdated tables, correct definitions and Comprehensive Plan references, and may include other related actions.

    SEPA Threshold Determination

    On July 7, 2020 a Determination of Significance (DS) and request for comments on the scope of the Environmental Impact Statement (EIS) was issued. No change to the DS is proposed, however additional alternatives are being considered in the EIS, as described below.

    Location

    The focus for the proposed Comprehensive Plan and Municipal Code amendments is the entire City of Sammamish within municipal boundaries.

    Proponent

    City of Sammamish

    EIS Scope

    The City of Sammamish has determined that this proposal may have a probable significant adverse environmental impact. An environmental impact statement (EIS) is required under RCW 43.21C.030 (2)(c) and will be prepared.

    Based on the prior scoping process conducted for this proposal, the lead agency has identified the following areas for discussion in the EIS: earth (steep slopes, landslide hazards), water resources (water quantity and quality, stormwater), plants and animals (tree canopy, fish), land use, plans and policies, population and housing, transportation, including impacts on transportation-related greenhouse gas emissions and evacuation routes, and consideration of utilities (broadband access) to the scope of analysis.

    Alternatives considered in the EIS are anticipated to include the following:



    Alternative

    Potential Key Features

    1

    No Action

    No changes to existing policies and regulations

    2

    Transportation Level of Service (LOS) Standards

    • New LOS standards for intersections and key corridors and roadway segments
    • No changes land use assumptions
    • Changes to transportation infrastructure to meet new LOS standards.

    3

    Transportation LOS Standards with transportation-efficient land use patterns

    • New LOS standards for intersections and key corridors and roadway segments
    • Transportation-efficient land use patterns consistent with the existing Comprehensive Plan
    • Changes to transportation infrastructure to meet new LOS standards

    4

    Transportation LOS Standards with transportation-efficient land use patterns and transportation network improvements

    • New LOS standards for intersections and key corridors and roadway segments
    • Transportation-efficient land use patterns consistent with the existing Comprehensive Plan
    • Transportation infrastructure and management changes including network improvements for greater efficiency and to meet new LOS standards.

    Scoping

    Scoping is the process of identifying the elements of the environment to be evaluated in an EIS.

    Scoping is intended to help identify and narrow the issues to those that are significant. The

    scoping process includes a public comment period so that the public and agencies can comment on key issues and concerns. Following the comment period, the City considers all comments received and determines the scope of review for the environmental analysis (WAC 197-11-408(4)).

    Comment Period

    There is no comment period associated with this optional revised scoping notice, pursuant to WAC 197-11-408(4). The City of Sammamish previously issued a DS / Scoping Notice on July 7, 2020 and conducted a 24-day comment period. Following the comment period, the City prepared a scoping report that acknowledged comments received and identified potential changes to the scope of the EIS. These changes are included in the description of the areas for discussion in the EIS, above.

    Public Participation

    The community is encouraged to continue to participate in the EIS process. The issuance of the Draft EIS (DEIS), anticipated in May 2021 will commence a 30-day public comment period, which is the next opportunity for public input. Please refer to the tentative project timeline available on the project webpage located here: https://connect.sammamish.us/eis. Comments received during this comment period will be addressed in the Final EIS (FEIS). Additionally, prior to any legislative action by the City Council, a public hearing will be held.
