The U.S. Army Corps of Engineers (Corps), as part of an interagency effort with the U.S. Environmental Protection Agency (EPA), the U.S. Fish and Wildlife Service (FWS) and the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS), is announcing the availability of the final 2018 National Wetland Plant List (NWPL). The Federal Register Notice for the 2018 NWPL update can be found here: https://www.govinfo.gov/content/pkg/FR-2020-05-18/pdf/2020-10630.pdf.

The NWPL provides plant species indicator status ratings, which are used in determining whether the hydrophytic vegetation factor is met when conducting wetland delineations under the Clean Water Act and wetland determinations under the Wetland Conservation Provisions of the Food Security Act. Other applications of the NWPL include wetland restoration, establishment, and enhancement projects. The list is effective as of May 18, 2020 and will be used in any wetland delineations performed after this date. Completed wetland delineation/determination forms should reference the version of the NWPL used to complete the form.  The final NWPL is available at http://wetland-plants.usace.army.mil/.  State, regional, and national lists can also be downloaded from this site.

Updates on the Chehalis River Basin Flood Control Zone District Proposal

Applicant's Proposal Description:

The Chehalis River Basin Flood Control Zone District (applicant) is proposing construction of a water retention facility and associated infrastructure on the main-stem Chehalis River south of the Town of Pe Ell, Washington. The facility would have capacity to provide 65,000 acre-feet of temporary flood storage during major floods, and would be constructed with a foundation to allow the future expansion of its water retention capacity. The Chehalis River would flow normally during regular conditions or small flood events. The top of the dam structure would be 1,220 feet long with a maximum structural height of up to 254 feet including 3 to 5 feet of freeboard for safety. The dam is proposed to include a 210-foot-wide emergency spillway, discharging into a 70-foot stilling basin. The applicant also proposes to raise the elevation  of the Centralia-Chehalis Airport levee in Chehalis, Washington.  The levee would be raised 4 to 7 feet, along with raising Airport Road 1,700 feet along the southern extent of the airport. The proposal is in pre-application status.
