ENVIRONMENTAL REVIEW

NOTICE IS HEREBY GIVEN that the City of Dayton has received a SEPA Environmental Checklist and other environmental reports and studies from the US Fish and Wildlife Service (USFWS) including an Environmental Action Statement (NEPA Categorical Exclusion) relating to a proposed project to repair a weir on the Touchet River at the Dayton Pond Intake Facility.  The USFWS intends to repair the current weir and install a new Obermeyer Weir on the Touchet River, within a parcel owned by the City of Dayton (Columbia County Parcel #264771). The current weir has experienced erosion during high flows and is now undermined, causing concerns for stability of the structure and safety concerns for the public. The proposed work will stabilize the existing structure and riverbed both upstream and downstream. The installation of the new Obermeyer Weir will maintain the river channel.

The proposal site is located in the Touchet River (Hydrologic Unit Code 170701020308) east of the terminus of S Cottonwood St. in Dayton, west of the USACE levee, and situated in Section 30, Township 10 N, Range 39 E, W.M.  Geo ID: 1160200350000. Full legal descriptions are on-file with the City of Dayton and available upon request; the parcels are within Rainwater and Mustard, Tax 35 (Rock Hill).  The weir is located on Columbia County parcel no. 264771. Other potentially affected parcels are nos. 264569, 264768, 264773, and 275544.  There is no address assigned.
