This assessment generally follows Mason County's Shoreline Stabilization Submittal Checklist as adopted in May 2018. 1 visited the site on four occasions in December between 2/7/23 &2/20/2023 to collect topographic information and to verify measurements and feature locations. Measurements were made with 100 foot and 200 foot long fiberglass surveyor's tapes and other field equipment common to surveying. Software employed in creating a site plan and writing this report included AutoCADTM 2024,and MicrosoftTM Office Word 2003. Slopes on the northwesterly area of the property were measured as steep as 27%as identified on the accompanying site plan.With slopes on or within 300 feet of the property exceeding 15%with a height of 10 feet or more,Mason County requires a geotechnical assessment to be developed to address stability issues relating to the property's development. File.C.lProfcctsiRoush�ShorelineStahtHzation 4)1 1 of 6 4/8/2024 TAHJA ENGINEERING, Inc. PO Box 235, I-loodsport, WA 98548 (360) 877-9512 The following elements are required by Mason County to be addressed in a Shoreline Geotechnical Assessment prepared to comply with Mason County's Shoreline Master Program, Shoreline Stabilization Section 17.50.340. Site Development& Landowner Concerns: The Roushs retained. Integrated NW Construction to replace a pier and other features as identified in Integrated NW Construction's Scope of Work(attached)as well as the project drawings produced by myself dated 4/9/2024(attached). The work complies with MCC 17.50.340 B.2 a.i,and a.iii in that the bulkhead provides protection to the residence on the property and the septic system components,and that it provides the only access associated with the principal use of the property that cannot be feasibly relocated. Due to the deterioration of the wood piles and pier/deck components,the Roushs are concerned about safety and the use of the shoreline features to access lake Cushman. The attached plans provide the locations of the existing features as well as the completed repairs and replacement items. The existing residence(Built—2002)is roughly 43' horizontally upland from the existing bulkhead with an average downslope of 27°.No wetlands or surface water drainage system adverse issues were identified. Site Vegetation: The site vegetation has been planted and maintained as landscaping with naturally occurring vegetation surrounding the residence. Discussion of Geologic Conditions: The site is located on the easterly shore of Lake Cushman Reservoir approximately 14 miles west of Hoodsport, Washington on the Olympic Mountain foothills. The general slope of the property from N Potlatch Drive to the top of the bulkhead is approximately 27%. Probing with a 4' rod found a moderately dense loamy sand(weathered till)covering most of the site to a depth between 3 &4' deep. Driven pipe-piles were typically driven to refusal at 12 to 14'. Probe locations and depths to the underlying firm hard soil layer are shown on plan sheets 1 &2. Inspection of the Washington State Interactive Geologic Map indicates that the site soils are Continental Glacial Deposit of the Fraser Glaciation, Vashon Stade described as soil category Qgo&Evcr,which are described as follows: File:C':IProJecisiRousliLSitorelute 5tabilizaii(m Rpt 2 of 6 4/8/2024 TAHJA ENGINEERING,Inc.

Inspection of the Soil Survey Map of Mason County found the soils listed as"(Hd)Hoodsport gravelly sandy loam,5 to 15 percent slopes.The Hoodsport soils are not listed in the County's Resource Ordinance s erodible soils. Inspection of the Washington Coastal Atlas, landslide hazard section, found the site located in an area identified as"stable". File:C. Iti,t 3 of 6 4/8/2024 TAHJA ENGINEERING,Inc. PO Box 235, Hoodsport, WA 98548 (360)877-9512 The project area lies at the base of the Olympic Mountain Foothills which can be characterized as a mix of ravines,valleys,and a gentle sloping shelf which connects the foothill plateau with the steep Olympic Mountains to the west.The immediate upslope geomorphology of the Roush property may be described as"hilly". Assessment of Relevant Wetlands& Surface Water Drainage: The general slope of the property helps keep the property well drained and dry.No evidence of rutting or stormwater channeling on the Roush or neighboring properties were evident during site visits to the property. The property is located fairly high(740-feet+)above the Hood Canal Sea Level elevation.No indications of groundwater surfacing,or wetlands were found on or around the property. Assessment of Site Vegetation: The Roushs maintain the vegetation in their yard with naturally occurring native vegetation and landscape plantings.The overall site may be considered natural. Assessment of Regional/Site Geology:Approximate depth to hard or competent soil. Soil probe locations&depths are shown on plan sheets 1 &2 along with measured depths to the underlying hardpan layer. Most of the undisturbed areas have a moderately dense soil layer approximately 36-inches deep overlying the strongly cemented till or basalt rock. Assessment of Regional/Site Geology including the influence of Wave or Tidal Processes: The Roush property and residential properties surrounding the site display no evidence of recent slope instability or earth movement. The Roush and surrounding properties are constantly subject to erosion from wave and"tidal action"—annual raising and lowering of the lake's surface water elevation between M 710 feet sea level and 738 sea level". With the shoreline being annually submerged and then exposed,the freeze thaw environment erodes the entire shoreline and roughly I to 2"of shoreline elevation is eroded away each year. Evaluation of Erosion or Flooding Issues: The residence was built in 2002 and has not been subject to any erosion or flooding issues other than the shoreline and bulkhead deterioration. Evaluation of the Amount of Time until Primary Structures or Major Utilities will be damaged by Wave or Tidal Action: If the bulkhead and slope behind the bulkhead are not maintained,the bulkhead could fail within a couple of years.The existing septic system was installed 54 feet landward of the Lake Cushman shoreline,and any loss of ground between the existing bulkhead and septic drain field would create a potential public health hazard.The existing residence is located rouhly 35 feet behind the existing bulkhead. Discussion of Alternative Approaches to reduce the risk from Erosion on the site: The bulkhead could benefit from having logs anchored along the toe of the existing bulkhead, no "soft"armoring erosion control features have been found to be successful. Discussion Describing the proposed shoreline stabilization is the minimum Necessary: The shoreline armoring being repaired has lasted several decades,and unless it is allowed to File:C.WrojectslRoushlShoreline Stabilkation Rpl 4 of 6 4/8/2024 TAHJA ENGINEERING,Inc.

The BE was prepared for Jeffrey and Dabney Roush for their property located at 1330 N Potlatch Dr, Hoodsport,WA 98548. The proposed project is on a residential lot located on the east shoreline of Lake Cushman. This addendum serves as a modification to the existing Biological Evaluation,aiming to reduce the planting plan to a 1:1 ratio while maintaining the overall integrity of habitat conservation efforts. The BE was revised on 2/21/2023 to reflect the changes to the proposed project.The changes included updating the design to a 300 square foot fixed pier attached to a 48 square foot walkway to anchor the pier to the uplands,removing the proposed ramp and float from the design,and installation of driven piles instead of piles encased in concrete. The mitigation outlined in the BE was proposed to meet the requirements of US Army Corps of Engineers since the original project would have been under their jurisdiction. However,the modifications to the design removed the project from USACE jurisdiction. Therefore a 1:1 ratio of mitigation is appropriate to compensate for the proposed project impacts outlined in the BE. The total area of impacts from the new pier and walkway is 348 square feet, as such the native planting plan can be decreased to 348 square feet.This is a reduction from the originally outlined planting plan which called for 830 square feet. Spacing of the native plants shall achieve the following as a minimum standard: • Trees will be spaced 10-foot on center • Shrubs five(5)-foot on center • Herbs four(4)-foot on center Given the spacing requirements,the ideal combination is 26 plants for the 348 square foot area: • 3 trees • 15 shrubs • 8 herbs This combination ensures that the planting densities for trees, shrubs, and herbs are maintained while optimizing the use of the available area.Adjustments can be made based on the specific species and their space requirements as well as site conditions. Refer to the BE for proposed native species,performance standard specifications,maintenance requirements, and details of the monitoring reports. All plants,with the exception of the trees,will be planted from directly behind the bulkhead (landward)up to 10-feet back.The trees shall be installed in a way so the roots at maturity will not affect the bulkhead structure,therefore they will be at least 10-feet upland from the bulkhead. Due to the close proximity of the existing rock retaining wall in this area,trees must be planted upland to prevent the roots from compromising the structure at maturity. The adjustments proposed in this addendum are based on a comprehensive review of the BE and proposed project.This addendum is intended to reduce excessive mitigation requirements while achieving no net loss to the local habitat. This addendum was written by Sarah Kupers, Habitat Biologist with Integrated NW Construction. Mrs. Kupers holds a degree in Environmental Science and has over five years of experience in habitat management and conservation planning. Mrs. Kupers was previously employed as an Area Habitat Biologist with WDFW,where she was responsible for reviewing and approving mitigation plans submitted with Hydraulic Project Approval (HPA)permit applications.

Forty plants w" '' . The exact location of the plantings will be at the applicants' discretion. Due to the potential for the roots of trees and large shrubs to damage the bulkhead, especially during summer drought conditions, it is recommended that any trees or large shrubs be installed along the landward margin of the proposed planting area. As per United States Army Corps of Engineers (USACE) stipulations,the landward edge of the shoreline mitigation area must be no farther than ten-feet from the ordinary high water mark and orientated parallel to the shoreline. Also, as per USACE requirements, plants will be installed that are native to the area. Prior to installing new plants, non-native, invasive vegetation will be removed by hand (with hand tools) or cut back from the planting area. Non-native, invasive Roush Biological Evaluation 5 vegetation in the mitigation area shall be removed at least twice a year or more frequently, if necessary. One to five gallon or bare root vegetation shall be installed between late fall and early spring. The planting area shall be planted with trees and shrubs evenly dispersed or with the trees at the corners and shrubs across the middle. Organic bark or other appropriate organic mulch shall be used to mulch the newly installed plants and minimize runoff from topsoil. Plants will be watered as necessary to ensure plants receive adequate water for the first three years. Due to the close proximity of Lake Cushman, no herbicides, pesticides, or fertilizer will be used in this project. The following native trees are proposed for installation: Shore pine(Pinus contorta), Sitka spruce(Picea sitchensis), Western red cedar(Thuja plicata), vine maple(Ater Circinaturm),Douglas fir(Pseudotsuga menziesii), and willow(Salix spp. including scouleriana, sitchensis, and/or hookeriana). The following native shrubs are proposed for installation: ,Oceanspray(Holodiscus discolor),Nootka rose(Rosa nutkana),tall Oregon-grape(Berberis aquifolium . Indian lum Oemleria cerasiformis),Pacific ninebark(Physocarpus capitatus), snowbrush(Ceanothus velutinus var. hookeri),ever een huckleberry Vaccinium ovatum ,red huckleberryVaccinium arvi olium , ceidentale), snokvberry (Syny?horicarpos albus), saaal (Gaultheria shallon),tall Oregon-gr , (Berberis aquf)liurn), svu id fern (, ystichum munitum),, kinnik' pick �A.�f os44l� IR�.�x��r Several of the above native species,which are common to the Lake Cushman area,are not included on the USACE's approved planting list.They were added because the list does not include enough upland shrubs that will thrive at the site. The applicant's may add plants from the USACE list at their discretion. Performance Standards What constitutes successful mitigation?Providing a habitat that will be functionally equivalent to one that will be lost(Zedler 1996). The creation of an ecosystem requires establishment of both structure and function. Structure can be described by the measurement of attributes such as composition and biomass at one point in time. Describing function requires the examination of complex processes that occur through time. In a mitigation context,there should be clear performance standards for both structural and functional attributes;however,while structure can readily be assessed, there are no easy methods for assessing function. Therefore,mitigation evaluation for this project will focus on structure. Measureable specific criteria for the evaluation of project success include: •Vegetation survival. Roush Biological Evaluation 6 *Eradication of non-native,invasive species The mitigation plantings shall meet the following performance standards for a period of five years following installation: Year 1 &2: 100%survival of all installed plants Year 3 thru 5: 80%survival of all installed plants Maintenance In the event that monitoring indicates project performance standards are not being met, the cause of the inadequacy or failure shall be determined and appropriate corrective measures implemented.All dead plants shall be replaced throughout the monitoring period. If mortality is due to too little water,the watering system/schedule shall be evaluated and changed as appropriate.Non-native, invasive vegetation in the mitigation area shall be removed at least twice a year or more frequently, if necessary. Monitoring Reports Monitoring reports are due annually by November 30a' for five years. The first shoreline mitigation planting area monitoring should occur in the first September after plant installation. Monitoring reports must include: •A completed one page monitoring report.A template is available at the following link: hqp://www.nws.usace.army.mil/Missions/Civil-Works/Re ulg artory/Forms/. *The as-built site plan updated to show any changes that have occurred to the shoreline mitigation planting area since the last report, such as plants that have died and been replaced. •Photographs taken in September from the previously established photopoints. The photos must be dated and labeled with the photopoint and the direction of the photo. 2.2 Timing Work will be completed over an approx. fourteen(14)day period during daylight working hours normal to a rural neighborhood. Work will only take place when the waters of Lake Cushman have been lowered,which is generally between October and April.
