Woodland Islands Habitat Restoration Project (DOE/EA  - 2006/SA - 10)
Cowlitz County, Washington


BPA proposes to fund the USACE and the community organization, Columbia River Estuary Study Taskforce (CREST), to place and grade sediment at two locations within the Lower Columbia River, from river mile 84 to 86, adjacent to the Woodland Islands to establish juvenile rearing habitat for thirteen species of salmonids listed under the Endangered Species Act. The USACE would obtain sediment from ongoing dredging actions in the mainstem Lower Columbia River necessary for maintaining the Federal navigation channel, and place and grade the sediment on subtidal areas to raise the bathymetric elevation to increase shallow water habitat for juvenile salmonids. The deposited sediment would be graded to connect with the existing shoreline of the islands, and to establish new areas of submerged and unsubmerged lands. The submerged areas would be graded to establish a descending sloped shelf to provide shallow water rearing habitat attractive to salmonids. The unsubmerged areas would be graded to create areas of dredged material with topographic variation that would encourage development of native shrubs and ground cover to benefit wildlife species. These unsubmerged areas would be allowed to revegetate naturally from ambient propagules and by targeted plantings of native plants.

Restoration activities associated with the proposed action have the following five overarching objectives:

Objective 1: Increase rearing/foraging habitat for juvenile salmonids

Objective 2: Increase flood refugia for juvenile and adult salmon

Objective 3: Increase floodplain habitat complexity

Objective 4: Increase quality riparian habitat

Objective 5: Decrease the amount and extent of non-native vegetation


BPA prepared a Supplement Analysis (SA) following the procedures in DOE’s NEPA Implementing Procedures at 10 CFR 1021 to the Columbia Estuary Ecosystem Restoration Project Environmental Assessment (Programmatic Estuary EA). The Programmatic Estuary EA analyzed the environmental impacts anticipated for restoration projects within the Columbia River Estuary, with the intent of facilitating and streamlining future site-specific project reviews.
This SA considered project specific impacts within the Columbia River estuary as a result of the Woodland Islands Habitat Restoration Project. The SA describes anticipated impacts to fish; hydrology and hydraulics; water quality; geomorphology, soils, and topography; sediment quality; air quality; wildlife; wetlands, floodplains, and vegetation; land use and recreation; cultural resources; socioeconomics; visual resources; noise, hazardous waste, public health, and safety; transportation and infrastructure; and climate change.
BPA did not conduct independent public scoping for this project due to the project’s consistency with the analysis provided in the Programmatic Estuary EA, for which a finding of no significant impact (FONSI) was issued on July 7, 2016.
The schedule for the environmental review was as follows:
NEPA analysis and documentation                    April 8 2020 – June 17, 2020  
Construction start                                              July 15, 2020    
BPA released its supplement analysis for the Woodland Island Habitat Restoration Project. The supplement analysis is available at the link below.
