Notice of Application and SEPA ...

Notice of Application and SEPA Determination: NOTICE IS HEREBY GIVEN that the City of Leavenworth has received the following application and expects to issue a Mitigated Determination of Non-significance (MDNS) for the City of Leavenworth Water Main Replacement. You are invited to review the files and make comments. Comments received by February 13, 2025 will be addressed in the City staff review. Shoreline Exemption LUA2024-090 The City of Leavenworth needs to expand the capacity of its existing water transmission main that connects the City wells located on parcel no. 241714111000 to the City water system. The City proposes to replace approximately 5,000 linear feet of existing 12-inch-diameter water main with a 24-inch-diameter water main from the well site to Hwy 2, along Hwy 2 to Mill St. The replacement main in the rights-of-way will be a new pipeline located within the roadways. The project begins at 9101 Icicle Road, where the City wells are located. The project then continues along the rights-of-way (ROW) of Icicle Road to Hwy 2, within the Hwy 2 ROW east of Icicle Road-Hwy 2 intersection to Mill Street. The well site is zoned RP (Recreation Public). The project area is approximately 7 acres. SEPA Environmental Review: City of Leavenworth has reviewed the proposed project for probable adverse environmental impacts and expects to issue a Mitigated Determination of Nonsignificance (MDNS). This determination is based on the file of record, including but not limited to: Design Plans, JARPA application, SEPA Checklist, Archeological Monitoring Plan and a Geotechnical Report. The proposed changes will not result in new impervious cover or adverse environmental impacts. Additional mitigations measures are necessary because of the high probability of archeological findings and the proximity to the Wenatchee River, a Shoreline of the State. The optional DNS process in WAC 197-11-355 is being used. This may be your only opportunity to comment on the environmental impacts of the proposed project. The following conditions are likely to be added to the MDNS: 1. The Plateau CRM Archeological Monitoring Plan dated April 2024 shall be closely followed to ensure that no archeological sites are disturbed. 2. Plateau CRM shall attend the preconstruction meetings with the City of Leavenworth and the Contractor to give direction on archaeological monitoring. No ground disturbing activities shall take place prior to consultation with Plateau CRM. 3. All recommendations within the Geotechnical Memorandum prepared by RH2, dated January 17, 2025, shall be closely followed. 4. A Construction Stormwater General Permit shall be obtained from the Department of Ecology prior to ground disturbance. 5. Best Management Practices (BMP’s) shall be followed to mitigate for erosion and sediment control. Agencies, tribes, and the public are encouraged to review and comment on the proposed project and its probable environmental impacts. Comments must be submitted by February 13, 2025, to cbarry@cityofleavenworth.com. Materials may be reviewed by the Permit Portal, https://cityofleavenworth.com/city-services/gis-permit-portal/.
