How can Grays Harbor County plan to protect low-lying communities in unincorporated areas, important natural resources and critical infrastructure from rising sea levels and mitigate future conditions projected from climate change hazards?
This is the central question that Grays Harbor County is trying to address with support from its consultants with the County’s SLR Vulnerability Assessment and Adaptation Study. We invite you to be a part of this important conversation.
Project Overview
Grays Harbor County, with its extensive coastline and intertidal lands, is heavily influenced by ocean waves, currents, and tides. These natural forces shape the area's unique ecosystem but also pose risks, especially with rising sea levels. High tides and storm surges can lead to flooding and erosion, impacting low-lying communities, infrastructure, and natural habitats.

Key Points:
- Location: Grays Harbor County, including open coast beaches, bay/estuarine shorelines, and riverbanks exposed to tides
- Challenges: Rising sea levels, flooding, erosion, and potential saltwater intrusion into groundwater.
- Project Study Area: The project study area includes the unincorporated areas of Grays Harbor County, excluding tribal reservations. All jurisdictions with their own Shoreline Master Plan (SMP) are excluded1.
- Goals:
- Assess risks and develop strategies to manage sea level rise.
- Update local plans and regulations to address these challenges.
- Engage with the community and stakeholders for input and feedback.
- Identify and prioritize projects to mitigate hazards.
- Seek funding opportunities for these initiatives.
Success Factors:
- Collaboration with stakeholders.
- Effective communication and planning.
- Designing resilient infrastructure.
- Securing funding for projects.
Public Outreach:
The project team will discuss potential adaptation strategies to address climate change impacts, considering public and stakeholder input.
Funding:
Washington State Department of Ecology’s the Shoreline Planning Competitive Grant Program for the 2023-25 biennium.
