Project Overview
The Aberdeen-Hoquiam Flood Protection Project is comprised of two critical levees, the North Shore Levee and the North Shore Levee – West Segment, which are needed to protect the Cities of Aberdeen & Hoquiam.
Coordinated Coastal Resiliency Planning
The Cities of Aberdeen and Hoquiam are working together on coordinated approach to reduce flooding, promote community development, and support salmon recovery efforts. The Cities are following a two-pronged approach to implement the Coastal Resiliency Master Plan and design / construct a protective levee system. The communities are impacted by a complex interaction of different types of flooding:
These local efforts align with the regional work of the Chehalis River Basin Flood Authority resulting in both a Master Plan and preliminary design and approval of a levee system.
North Shore Levee - West Segment
The North Shore Levee—West Segment, estimated to cost $40 million to construct, will build a 4.7 mile levee (earthen, concrete and sheet pile) bordering the west side of Hoquiam. This levee will protect local residents and build resiliency in the face of future flood events, as well as retain existing businesses, jobs and residents which have been on the decline in this community. Questions on the North Shore Levee - West Segment can be submitted to Brain Shay, City Administrator, City of Hoquiam BShay@cityofhoquiam.com
Activities- North Shore Levee - West Segment
The $4 million will be used to complete final design and Right of Way Acquistion to achieve shovel ready construction status in 2023. Final Design is underway and may result in some changes to the current alignment.
The Federal Emergency Management Agency (FEMA) has issued a Conditional Letter of Map Revision (CLOMR) for the proposed North Shore Levee - West Segment. FEMA's issuance of a CLOMR is confirmation that, once the levee is built and certified, FEMA will redraw local Flood Insurance Rate Maps (FIRMs) to reflect levee protection. Within the limits of levee protection, areas that are currently mapped Special Flood Hazard Area (SFHA) due to coastal flooding will be removed from the 100-year coastal floodplain and remapped as Zone X. This is a major milestone for the North Shore Levee project as it ensures that the project, once constructed, will result in the intended mapping changes.
The City of Hoquiam is working to design and build the North Shore Levee - West Segment to provide flood protection for low-lying parts of Hoquiam, west of the Hoquiam River, north of the Chehalis River and Grays Harbor Estuary. This sement is a continuation of the North Shore Levee project directly east of the Hoquiam River in East Hoquiam and West Aberdeen. That project received a CLOMA in 2017.
The purpose of the levee is to protect the downtown business district, critical infrastructure, and residences in the City of Hoquiam from damaging floods and to reduce the finanical burden of flood insurance and floodplain development regulations. The protected areas will be removed from the Special Flood Hazard Area Zone AE and placed in a Zone X. The City of Hoquiam has suffered from long-term economic depression and high unemployement. The removal of mandatory flood insurance for a majority of properties located within the floodplain will provide a desperately needed boost to the local economy.
The next step in this process is to finalize the design of the Levee and go through the ROW acquistion and permitting processes. Funding to continue design and permitting has been allocated by the Chehalis River Basin Flood Authority for the 2021-2023 biennium. Construction will be bid ready by the end of 2023.
