Alder Street SEPA ENVIRONMENTAL CHECKLIST Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use "not applicable" or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision- making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non-projects) questions in Part B - Environmental Elements—that do not contribute meaningfully to the analysis of the proposal. A. Background 1HELPI 1.

The project is located within Section 19,Township 22N, Range 01W,Willamette Meridian. The center of the Site is at Latitude 47.3777796N and Longitude-122.845629W. Figures are provided in Appendix A. Mike Layes, a Qualified Wildlife Biologist and Professional Wetland Scientist conducted research and investigated the Site on February 20, 2020. The Site and adjacent areas within 1,000 feet were investigated for the presence of listed Fish and Wildlife Habitat Conservation Areas (FWHCA)regulated under MCC 8.52.170-Fish and wildlife habitat conservation areas. Potential impacts to FWHCA were assessed and a mitigation plan was developed. 1.1 SCOPE OF SERVICES The scope of work for this study was limited to the following tasks: • A review of documents and maps readily available, including the Washington State Department of Fish and Wildlife's Priority Habitat and Species (PHS)data base and the United States Department of Fish and Wildlife's online Information for Planning and Consultation (IPaC). • A property assessment to observe existing site conditions and identify listed Fish and Wildlife Habitat Conservation Areas(FWHCA)regulated under MCC8.52.170-Fish and wildlife habitat conservation areas, and to identify potential mitigation opportunities and management recommendations. • Review of federal,state,and local regulations and management recommendations pertainingto the listed Fish and Wildlife Habitat Conservation Areas identified during the site visit and document review activities. This includes applicable information from Management Recommendations for Washington's Priority Habitats and Species. • A Habitat Management Plan detailing the proposed project, an analysis of perceived project impacts to identified Fish and Wildlife Habitat Conservation Areas, and if necessary, mitigation and management actions intended to offset any such impacts to Fish and Wildlife Habitat Conservation Areas. 1.2 SITE DESCRIPTION The Site is located at 420 East Lakeshore Drive, Allyn, WA 98524. Access to the property is on the west side of East Lakeshore Drive at the intersection of East Channel Drive. The Site gently slopes down west from East Lakeshore Drive, approximately 210' to the shoreline of Lake Anderson. Adjacent properties to the north and south are developed with single family residents,each of which has a developed/landscaped lake front and private residential dock. The Site is undeveloped, and covered with native coniferous forest dominated by Douglas Fir over an understory of Evergreen Huckleberry (Figure 3). The shoreline has been previously cleared of trees and shrubs and is dominated by Reed Canarygrass. 277.001 Kriegbaum ACERA Habitat Management Plan March 2020 1 Observations of plant species found during field work activities were noted. Table 1 provides a summary of plant species observations. These observations are not intended to provide a complete inventory, but a basic list of common flora species found at the Site. Table 1.

Construction of float and walkway will occur offsite at contractor facility; parts will be delivered to local boat launch (-0.2 mile south of property); floated to property and installed. Manual Installation will require driving two 2" pin piles into lake bottom for the foat,two angle pin piles into land at shore to secure walkway; float and walkway are coupled by two hinges. Entire installation is within the 100-year floodplain. Detailed engineered plans for the float will be submitted separately. 2 FISH AND WILDLIFE HABITAT CONSERVATION AREAS The preparation of this report included review of several existing sources of documentation, review of agency databases and maps. A field reconnaissance was conducted to review habitat conditions and verify written documentation. The review of existing information includes, but was not limited to,the following documents and information sources: 2.1 WA STATE FISH AND WILDLIFE DATABASE REVIEW The Washington Department of Fish and Wildlife's (WDFW) Priority Habitats and Species (PHS) database was queried on March 9, 2020 to determine if Fish and Wildlife Habitat Conservation Areas (FWHCA)regulated under MCC 8.52.170 within the project vicinity (Figure 5). According to the PHS database review, Coho Salmon (Oncorhynchus kisutch),Steelhead Trout(Oncorhynchus mykiss),and Cutthroat Trout(Oncorhynchus clarki)occur within Lake Anderson. Cutthroat Trout are not regulated under MCC8.52.170. 2.2 US FISH AND WILDLIFE DATABASE REVIEW The United States Fish and Wildlife (USFWS) online Information for Planning and Consultation (IPaC)was queried on March 9 to determine if fish and wildlife species and habitats regulated under MCC8.52.170 Fish and Wildlife Habitat Conservation Areas(FWHCA)were within the project vicinity. The IPaC website shows that 5 species listed under the Endangered Species Act (ESA)are"known to occur or may be affected by activities on or near"the Site (Figure 6). However, the IPaC data shows that these species may occur anywhere within Mason County. Therefore, this information is not precise enough to determine if these species actually occur within the project vicinity. These 5 species are: Fisher (Pekania pennanti); Marbled Murrelet (Brachyramphus marmoratus); Streaked Horned Lark(Eremophila alpestris strigata);Yellow-billed Cuckoo(Coccyzus americanus); and Bull Trout (Salvelinus confluentus). The USFWS has designated Critical Habitat for these 5 species. No such USFWS Critical Habitat for these species is documented as occurring on or within the project vicinity. Based on habitat availability and documented sightings of these species, it is highly unlikely that any of these species occur within the project vicinity. 277.001 Kriegbaum ACERA Habitat Management Plan March 2020 3 2.3 SITE VISIT A site visit was conducted on February 20,2020. The Site and accessible areas within the vicinity were investigated for fish and wildlife species and habitats regulated under Fish and Wildlife Habitat Conservation Areas (FWHCA) regulated under MCC 8.52.170. Lake Anderson is the only FWHCA identified during the site visit. No other FWHCA were observed. 2.4 MASON COUNTY SHORELINE INVENTORY AND CHARACTERIZATION REPORT The Mason County Shoreline Inventory and Characterization Report was reviewed for Lake Anderson (Figures 6 and 7). According to this report Lake Anderson is 45.3 Acres, and is within WRIA 14 Kennedy—Goldsborough. The entire shoreline designation for Lake Anderson is Urban Residential. 2.5 PROJECT IMPACTS ON FWHCA The Project will take place within the waters of Lake Anderson. Construction of the float and walkway will take pace entirely offsite. The float and walkway will be secured to the shoreline as discussed in the project description at time of installation. Installation of the float and dock is expected to take less than one day. The Project will not affect any of the identified terrestrial FWHCA species or their habitats: (Fisher (Pekania pennanti); Marbled Murrelet(Brachyramphus marmoratus);Streaked Horned Lark(Eremophila alpestris strigata); Yellow-billed Cuckoo (Coccyzus americanus). Bull Trout (Salvelinus confluentus)is not documented as occurring in Lake Anderson, or its inlet/outlet (Anderson Creek)on in Sherwood Creek. Shallow lakeshore waters are not its habitat. Its presence within the project area is therefore highly unlikely to ever occur. There are no perceived impacts on this species from this project. Coho Salmon (Oncorhynchus kisutch) and Steelhead Trout (Oncorhynchus mykiss) are documented as present within the waters of Lake Anderson and its inlet/outlet (Anderson Creek) and within Sherwood Creek. Both of these species prefer streams and rivers as habitat, as opposed to shallow lakeshores. However,these species are likely to occasionally migrate through the project area, between the inlet and outlet streams of Lake Anderson. The project will not directly inhibit their migration route. The project will not affect water quality,quantity, or temperature. Minimal,temporary increased turbidity will occur during placement of the float and walkway. Perceived projects impacts will be alteration of lake shoreline habitat by placement of 180 square feet of overwater structure. Impacts to these two fish species will be minimal. The project is exempt from FWHCA buffer requirements according to MCC 8.52.170(E)(4)(e). 277.001 Kriegbaum ACERA Habitat Management Plan March 2020 4 Mitigation for project impacts include: • The walkway and float are the minimal size necessary to allow recreational access to Lake Anderson; • Construction of the walkway and float will take place completely offsite; • The design of the walkway and float will use 60% "fish friendly'open area decking; • 400 square feet of native shoreline restoration plantings. 3 RESTORATION PLAN This Restoration Plan (Plan)is intended to mitigate project impacts discussed above with installation of 400 square feet of native plantings. Two - 200' square feet planting areas were marked and flagged during to site visit, landward of the Ordinary High Water Mark of Lake Anderson. The approximate location of the planting areas (Area 1 and Area 2)are shown on Figure 9. Both Planting Area 1 and 2 are currently dominated by weedy invasive species including: Reed Canarygrass; Himalayan Blackberry; Curly Dock; and Yellow Arch Angel. Control and removal of these species will take place prior to installation of native plantings. Site conditions permitting, the optimum time for planting most native woody plant material appears to be the later part of winter and early spring (February-March). Planting instructions are provided in Figure 10. Instillation of native plants will enhance the existing shoreline functions in this area. Habitat and water quality improvements will include: • Increased plant species diversity, which will increase nesting, forage, cover, and pray opportunities for local native wildlife; • Filtration of sediments by ground cover plants and shrubs; • Erosion control from rooted ground cover plants and shrubs; • Dense plantings will provide screening of the shoreline from human disturbance. 3.1 PLANTING SPECIFICATIONS All plant materials will be native to the northwest, and preferably the Puget Sound Region. Plant materials will be propagated from native stock;no cultivars or horticultural varieties will be allowed. All plants shall be high quality restoration grade vigorous stock. Depending on project needs and timing, it may be necessary to acquire plant material through several local native plant nurseries, and some species may be unavailable. See Table 2 for a complete list of plant species and quantities. ACERA recommends the following licensed regional nurseries for procurement of native plants. • Black Lake Organic Nursery, Olympia, WA (360)786-0537 • Bog foot Environmental,Olympia,WA (360)866-7068 • (SEED) Inside Passage, Port Townsend,WA (360)385-6114 • Sound Native Plants, Olympia,WA (360)352-4122 277.001 Kriegbaum ACERA Habitat Management Plan March 2020 5 • Watershed Garden Works, Longview,WA (360)423-6456 • Woodbrook Nursery, Gig Harbor,WA (253) 265-6271 Plant species have been selected that are adapted to grow within the planting areas based on moisture tolerances, habitat adaption, and the desired plant community. The landscape contractor/applicant shall make a good faith effort to secure all species specified in this Plan. Native plant species substitutions may be authorized by the project biologist. Plantings will be generally installed at the quantities and densities specified below. Plants with the "FAC" designation should be generally planted closer to the shoreline,within each planting area.

After installation of the restoration plants and the spreading of mulch, care will be taken to hold the mulch back from the stems and trunks of restoration plants. 3.3 MAINTENANCE Maintenance shall consist of supplemental irrigation as necessary and replacement of dead or dying plants with appropriate vegetation specified in the planting plan. Irrigation of native plantings is recommended twice monthly during May 15th — October 15th of the first two years post installation. Reed Canarygrass should be cut back around each restoration plant, as necessary until they are established. 3.4 INSTALLATION INSPECTION AND MONITORING Compliance monitoring will consist of evaluating the mitigation plantings immediately after installation to confirm the plan was followed and plants were installed appropriately, and to verify that all design features agreed to in this plan have been correctly and fully implemented. Due to the small scale of this restoration project, before and after photos of each planting area should provide adequate proof that the restoration plants were installed appropriately. If required by the County, a walk-through survey will be conducted by the project biologist or qualified County Staff to serve as the"as-built survey". Any changes made in the field will be consistent with the overall objective of the plan. Following completion of the Installation Inspection and Monitoring, a summary technical memorandum will be prepared verifying that all design features have been correctly implemented. Any changes to the planting plan will also be discussed in the technical memorandum. Due to the small scale of this restoration project, no longterm monitoring is proposed. 4 CONCLUSION This HMP provides an analysis of impacts to FWHCA for new construction of a residential float (Kriegbaum Float Project)on Lake Anderson. Two regulated FWHCA species(Coho Salmon and Steelhead Trout)were identified as have a probable presence in the project area. Mitigation measures including minimizing the size of the project, offsite construction, and "fish friendly" design was utilized to offset impacts to these species. Additional mitigation measures included shoreline restoration using native plants. These mitigation measures adequately compensate for any perceived impacts to regulated FWHCA. The findings and conclusions documented in this report have been prepared for specific application to this project. They have been developed in a manner consistent with that level of care and skill normally exercised by members 277.001 Kriegbaum ACERA Habitat Management Plan March 2020 7 of the environmental science profession currently practicing under similar conditions in the area. Our work was also performed in accordance with the terms and conditions set forth in our proposal. The conclusions and recommendations presented in this report are professional opinions based on an interpretation of information currently available to us and are made within the operation scope, budget, and schedule of this project. No warranty, expressed or implied, is made. In addition, changes in government codes, regulations, or laws may occur. Because of such changes,our observations and conclusions applicable to this Site may need to be revised wholly or in part. 5 QUALIFICATIONS OF AUTHOR Mike Layes is a Wildlife Biologist with over 23 years professional experience.
