EXHIBIT C-3 Supporting Documentation 6 EXHIBIT C-3 June 21, 2021 Bart Catching Cowlitz County Building and Planning 207 Fourth Avenue North, Rm 119 Kelso, WA 98626 Re: Habitat Assessment Level II Updates. Dear Bart: Thank you for your assistance in process this permit. We have updated the permit application, Level II Habitat Assessment, and overall design plans to include the proposed replacement dock. Removal of the existing dock will take place concurrent with the shoreline stabilization work. The shoreline stabilization was also adjusted slightly in this currently updated proposal. The linear of the project area from 75 feet, the amount of material removed will be about 65 to 70 cubic yards, and the amount of rip rap needed for the project to about 150 cubic yards. Attached to this letter are the No Permit Required letter from the U.S. Army Corps of Engineers issued following our revisions in January 2021, which moved all aspects of the project outside of the OHWM of Lake Merwin. Also attached is the approval letter from PacifiCorps for this work. We met onsite with the Washington Department of Fish and Wildlife biologist (WDFW), George Fornes, and he has provided initial comments that will be included in the Hydraulic Project Approval application (HPA) to be submitted to WDFW following SEPA issuance by Cowlitz County. If there are any questions or concerns, please feel to contact Joanne at [email protected] or myself at [email protected]. Sincerely, Francis Naglich, Owner Senior Biologist Attachments: Approval from PacifiCorps No Permit Needed Letter from the US Army Corps of Engineers (Please note: This document includes outdated figures from January 2021).

After careful review of the plans and information submitted for PacifiCorp’s consideration under the processes identified in the Lewis River Shoreline Management Plan, PacifiCorp has determined that the overall proposed project as identified in the permit application and design drawings poses low risk from cultural resource, environmental and engineering standpoints and the project does not present itself as potentially having a negative impact on PacifiCorp’s hydroelectric facilities and related operations. PacifiCorp hereby grants its preliminary approval for you to move forward with the process of obtaining all permits and approvals from any required jurisdictional entities to commence replacement of the dock and stair system, and stabilization of a portion of the shoreline. Please note if additional agencies must consent to the proposed project, it is the ultimate responsibility of the applicant to determine which agencies must be contacted and from whom all necessary approvals should be obtained. PacifiCorp will need you to provide the following before it will issue its final approval/project permit: • Any and all applicable Federal, State and County compliance permits. Proof that these permits have been acquired must be furnished to PacifiCorp prior to the project taking place. • A completed geotechnical evaluation of the slope signed and stamped by a licensed geotechnical engineer. 825 N.E. Multnomah, Suite 1700 Portland, Oregon 97232 503-813-5700 Please note that PacifiCorp may require proof of a cultural resources review and evaluation prior to issuing its final consent to you to conduct any ground disturbing activities necessitated by any of the work you are proposing. Please feel free to contact me at 503-813-6211, or by email at [email protected] if you have any questions or concerns. Sincerely, Jasmine Murphy Jasmine Murphy Property Agent PacifiCorp Real Estate Management DEPARTMENT OF THE ARMY CORPS OF ENGINEERS, SEATTLE DISTRICT P.O. BOX 3755 SEATTLE, WASHINGTON 98124-3755 Regulatory Branch January 28, 2021 Mr. Ryan Hurley 7700 NE 182nd Avenue Vancouver, Washington 98682 Reference: NWS-2020-716 Hurley, Ryan (Hurley/Gibb Shoreline Stabilization) Dear Mr. Hurley: We have received your application for a Department of the Army (DA) permit to stabilize an eroding bank and remove an existing dock, tires, and debris at Lake Merwin, near 388 and 394 Woodland Park Lane, Ariel, Washington, as depicted on the enclosed drawings, dated January 21, 2021. We have reviewed the information you provided to us pursuant to Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act (RHA). We have determined that no action by the U.S. Army Corps of Engineers (Corps) is required for the proposed work described in your application and drawings. Under Section 10 of the Rivers and Harbors Act of 1899, a Section 10 DA permit is normally required for work or structures in or affecting navigable waters of the U.S. Because Lake Merwin is not a navigable water, a Section 10 DA permit is not required. Under Section 404 of the Clean Water Act, a DA permit is normally required for the discharge of dredged or fill material (e.g., fill, excavation, or mechanized land clearing) into waters of the U.S., including wetlands. Based on the information you provided, the proposed activity would not result in the discharge of fill material waterward of the line of ordinary high water of Lake Merwin (239.6 feet Mean Sea Level (full pool elevation)). Additionally, removal of the existing dock, tires, and debris would result in only incidental fallback of dredged material into Lake Merwin and the dredged materials would not be placed in a water of the U.S. Therefore, we have determined that no discharge would occur and a Section 404 DA permit is not required. Removal of the existing dock, tires, and any debris must be accomplished by hand or using an excavator from uplands with a “thumb” attachment to pick the items out of the water (without excavating or dredging the natural substrate) and placing those structures in containment to be transported to an upland disposal facility. If additional work, including excavation, dredging, filling, backfilling, or stockpiling material is required to remove a structure, or complete the bank -2- stabilization activity, a DA permit may be required and must be obtained before the activity can commence. While a DA permit is not required, local, State, and other Federal requirements may still apply. For assistance in determining other permit requirements for the proposed project, we recommend you contact the Washington State Office of Regulatory Assistance via the internet at www.ora.wa.gov. A copy of this letter will be furnished to Mr. Francis Naglich at Francis@eco- land.com. If you have any questions, please contact me at [email protected] or (206) 316-3049. Sincerely, Evan G.

  • Chapter 6 Recreation
    Chapter 6 Recreation Words in bold and acronyms This chapter describes existing recreation resources in the project area, and are defined in how the project alternatives could affect these resources. Related Chapter 32, information can be found in Chapter 5, Land and Chapter 7, Visual Resources. Glossary and Economic values of recreation in the project area are discussed in Chapter 11, Acronyms. Socioeconomics. 6.1 Affected Environment Recreation resources are found in both urban and rural portions of the project area within Cowlitz and Clark counties, Washington, and Multnomah County, Oregon. These resources include urban parks and greenways, developed facilities in rural areas such as campgrounds or trailheads, and undeveloped rural areas. Recreational activities within the three counties include boating, fishing, hunting, target practice, camping, hiking, swimming, picnicking, sports games, wildlife watching, ATV use, sightseeing, horseback riding, and mountain biking. These activities occur in dedicated areas such as parks and other developed recreation facilities, on motorized and non-motorized trails, and in dispersed areas such as open space (see Maps 6-1A through 6-1E). Although these maps show recreation resources throughout the project area, for this analysis, a study area for recreation resources was identified to include a 2,000-foot-wide corridor along the entire route of each action alternative, 1,000 feet on either side of the transmission line centerline. This study area includes all project facilities. In the western and southern portions of the study area, recreation resources are closely spaced, urban, and generally more fragmented. In the eastern portion, recreation resources tend to be larger, more contiguous, and more rural.

Catastrophic debris avalanche and ensuing erup­ tion on 18 May 1980 removed a vast portion of the volcano and created the large horseshoe- shaped crater. A widespread lateral blast removed almost all vegetation on nearby slopes north of the mountain and knocked down trees on slopes farther out (lower left). Large 'lestructive lahars that formed within minutes of the onset of the eruption swept down ! he east and west flanks of the volcano. Photograph taken on 24 July 1980 by Austin Post.

The County last completed a comprehensive update of its critical areas regulations in 2009. The County updated the wetlands section of its critical areas ordinance in 2014 to align with the updated Washington Department of Ecology Washington State Wetland Rating System. The State requires that Cowlitz County update it critical areas regulations on or before June 30, 2018, and every eight years thereafter (RCW 36.70A.130). This deadline must be met for the County to remain eligible to receive funds from the public works assistance and water quality accounts in the State Treasury. To support the County’s Critical Areas Ordinance update, The Watershed Company and Parametrix prepared this review of existing conditions and best available science (BAS). This review of existing conditions and BAS describes critical area resources within the County and documents BAS-based approaches to protecting the functions and values those areas provide. Existing conditions in the County are based on the County’s GIS mapping, existing County documents, and other publically available documentation.
