The National Wetland Plant List (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. To update the NWPL, the U.S. Army Corps of Engineers (USACE), 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 proposed changes to the 2022 NWPL and its web address to solicit public comments. The public will now have the opportunity to comment on the proposed changes to wetland indicator status ratings for two plant species in the Arid West (AW) region. In addition, we are accepting comments on the proposal to move from a two-year update cycle to a three-year update cycle for the NWPL. Finally, USACE is seeking comments on the overall NWPL update process. Comments must be submitted on or before March 21, 2023. Click here for a copy of the Federal Register notice more information.

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.
