The U.S. Army Corps of Engineers (USACE), as part of an interagency effort with the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, and the U.S. Department of Agriculture Natural Resources Conservation Service, is announcing the availability of the final 2020 National Wetland Plant List (NWPL).  The Federal Register Notice for the 2020 NWPL update can be found here: https://www.federalregister.gov/documents/2021/11/02/2021-23891/national-wetland-plant-list

The NWPL provides plant species wetland indicator status ratings, which are used in determining whether the hydrophytic vegetation factor is met when conducting wetland delineations under the Clean Water Act.  The list is effective as of November 2, 2021 and will be used in any wetland delineations/determinations performed after this date.  Delineations completed prior to this date may still use the 2018 NWPL.  Completed wetland delineation/determination forms should reference the version of the NWPL used to complete the form.  Please note the change in wetland indicator status ratings for the four species found in the table below.

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.
