Degrading river and stream water quality.

Degrading habitat on land, and in water and wetlands.

Reducing native aquatic species such as lamprey and mussels.

Reducing spring- and fall-run Chinook salmon, Coho salmon, and steelhead trout.

It would have significant adverse effects, mainly along the Chehalis River in the area above the flood retention dam and below it to the confluence with the South Fork of the Chehalis River.В These include: Under our analysis, the project would reduce flooding to buildings and infrastructure, including U.S. We looked at 17В different environmental elements including impacts to air quality, cultural resources, environmental health and safety, environmental justice, fish and aquatic species, habitat and land use, recreation, transportation, tribal resources, water, wetlands, and wildlife.

Our review studied the likely significant environmental impacts from the Flood DistrictвЂ™s project as well as alternatives. Study identifies significant environmental impacts The Board is expected to use the information in the environmental review, along with other information, to inform their recommendations for the long-term strategy. The Flood District's project evaluated in the draft environmental review is one of the proposed actions for consideration.

One part of the Chehalis Basin StrategyВ is to consider large-scale flood-damage reduction actions. Map of proposed changes at Chehalis-Centralia Airport, including raising existing leveeД¬ommunitiesВ in the basin are working with the Chehalis Basin BoardВ on a long-term strategy to reduce flood damage and restore aquatic species habitat in the Chehalis River basin.Artist rendering of Flood District's proposed flood retention dam on Chehalis River.Vicinity map showing location where Flood District's proposed projects would occur.The project is not intended to address flooding in all parts of the Chehalis River basin and would not stop regular annual flooding. The airport levee changes would raise and widen the Chehalis-Centralia Airport levee and nearby roads to increase levee protection level during catastrophic floods. The Flood District's proposed flood retention dam and associated temporary reservoir is intended to reduce damages from major floods from Pe Ell to Centralia triggered by rainfall in the Willapa Hills.

We also provided the Chehalis Basin Board with an update on the final EIS in November 2021. The Flood District has provided clarifications on the proposed project to be considered in the Final EIS.

Army Corps of Engineers, and the Flood District throughout the process. We have been coordinating with other state agencies, the U.S. The report will also provide responses to the substantive comments we received on the draft EIS. It will include a range of potential impacts based on high and medium climate change models from the University of Washington Climate Impacts Group. It will include revisions based on the public comments we received for the draft EIS as well as additional modeling and impact analysis. We are developing the final EIS and expect to release it in early 2023. Comments are valued equally, and responses will be included in the final EIS. Comments received are available to view and download. We held a public comment period on the draft state EIS from Feb.

A presentation on the draft EIS is available as slides or with audio. Our focus sheetВ has an overview of the findings of the draft EIS. Our draft stateВ Environmental Impact StatementВ analyzed how the proposal is likely to affect the environment under the State Environmental Policy Act (SEPA).
