Environmental Impact Statement (EIS)

Updates

A Huge Thank You!

Thank you to those of you who provided comments on the scope of the Pierce County 2023 Comprehensive Flood Hazard Management Plan (Flood Plan) and environmental impact statement.  Although the comment period has closed, we would still like you to take part in our Flood Hazard Survey. Please visit the below link to take the survey.

Due to current restrictions on public gatherings we are unable to host in-person scoping meetings. Instead, please view the recorded presentation below. Additionally, read more about the Flood Plan on this website and provide any comments via mail or email [email protected]. You are also encouraged to complete the survey to help us better understand what flooding means to you and how you have been impacted by past flood events. The survey can be accessed at piercecountywa.gov/floodsurvey. The SEPA Determination of Significance and Notice of Scoping can be accessed in the document library on the right.


Thank you to those of you who provided comments on the scope of the Pierce County 2023 Comprehensive Flood Hazard Management Plan (Flood Plan) and environmental impact statement. Starting in 2023 the Flood Plan will identify projects and polices that will reduce the impact of major flooding to the community to be implemented over a 10 year period. The 2023 Flood Plan takes a new approach - while past plans only addressed riverine flooding, the 2023 Flood Plan will also address coastal, groundwater, and urban flooding. 

Scoping was the first step in the EIS process. The comments received will help Pierce County’s Surface Water Management Division determine what issues should be considered in its technical analysis of potential alternatives, what environmental impacts and potential mitigation measures should be considered and evaluated, and what permits may be required. 

After review and consideration of the scoping comments, Pierce County will prepare a draft EIS that will cover aspects of the built and natural environment, including water, plants and wildlife, environmental health, and transportation, among other issues. The draft EIS and draft Flood Plan are expected to be issued for public review and comment in early 2023.

Even though the formal comment period has closed, Pierce County will continue to accept comments and answer questions throughout the development of the Flood Plan and EIS.  Comments and questions may be submitted by email at: [email protected] 

Pierce County continues to monitor the latest information from Governor Jay Inslee’s office, State Department of Health, and Centers for Disease Control & Prevention (CDC) regarding the COVID-19 coronavirus. We are planning to host meetings with stakeholders and members of the public online until further notice.


Stay tuned for details about upcoming opportunities to get involved. Sign up for project updates.

About the Environmental Review Process

The Flood Plan will go through the State Environmental Policy Act (SEPA) environmental review process with opportunities for public input. An environmental impact statement (EIS) will be prepared to evaluate the affected environment, impacts, mitigation measures, and unavoidable significant adverse impacts that would result from Pierce County‘s approval of the proposed Pierce County Rivers Flood Hazard Management Plan (Flood Plan) or an alternative to the Flood Plan. 

SEPA is intended to provide information to agencies, applicants, and the public to encourage the development of environmentally sound proposals. The environmental review process involves the identification and evaluation of probable environmental impacts, and the development of mitigation measures that will reduce adverse environmental impacts. This environmental information, along with other considerations, is used by agency decision-makers to decide whether to approve a proposal, approve it with conditions, or deny the proposal. SEPA applies to actions made at all levels of government within Washington State.

Opportunities for public input during the development of the EIS include scoping and the draft EIS. Please continue to check back for upcoming opportunities for your input.

How does the environmental impact statement (EIS) relate to the development of the plan?

The Flood Plan will go through a non-project environmental review process with opportunities for public input. Non-project environmental impact statements (EIS) are prepared for planning decisions that provide the basis for later project review. Non-project actions include the adoption of plans, policies, programs, or regulations that contain standards controlling the use of the environment or that will regulate a series of connected actions. There are two periods for public input:   

  • The “scoping” period where the public, tribal governments, and local, state, and federal agencies are invited to comment on the range of alternatives, areas of impact, and possible mitigation measures the EIS should evaluate. Public scoping meetings may be held during this period.
  • The draft EIS review period, where comments are requested regarding the merits of alternatives and the adequacy of the environmental analysis. Public hearings are often held during this period.

The scoping period was held December 14, 2020 - January 29, 2021.
