Indicate existing stormwater drainage to and from the site on the site map. Depict separate drainage basins on the site map, if applicable,and indicate acreage of each. The existing site consists of forest land and 0.43 miles of gravel logging road. There are two Type 5 streams crossing the site that may intermittently convey stormwater to the Bogachiel River. Otherwise, stormwater is naturally dispersed on-site. 6. Describe any excess levels of noise generated by the proposed use or activity: There will be no excess levels of noise generated by the proposed facility. Noise generated by the proposed road construction will consist of standard construction equipment,such as chainsaws, bulldozers,excavators, rollers,and dumptrucks. 7. Describe significant geographic features and critical areas (i.e., environmentally sensitive areas such as wetlands, streams, steep slopes,etc.)on the site. Indicate location on the site map. The proposed road realignment lies partially within a dormant, deep-seated landslide complex that extends approximately 750 ft. along the Bogachiel River. Slopes on the site generally range from 10-30%, with the steepest slopes 50-60%. There are two intermittent Type 5 streams that cross the site. 8.

Protect Low Impact Development BMP's Stormwater Site Plan DCD Dowans Creek Rd.doc—rev.11/4/2014 12 • • Low-Impact Development(LID)BMPs shall be protected during construction activity to prevent impacts from sedimentation and soil compaction.The BMPs relevant to protecting LID BMPs that will be applied for this project include: • Preserving Natural Vegetation(BMP 5-1.1.5) • Silt Fence(BMP 5-1.1.31) LID BMPs shall be installed in accordance with WSDOT Standard Specification Section 8-01 and the Contract Plans.To the maximum extent feasible,work shall be phased to minimize exposed soil thereby preserving natural vegetation and providing source control. 2. Adjacent Areas. a. Description of the adjacent areas that may be affected by site disturbance (e.g., streams, lakes, wetlands, residential areas, roads). The project site is surrounded by extensive forest land. The adjacent forested areas will be protected from affects related to site disturbance. b. Description of the downstream drainage path leading from the site to the receiving body of water(minimum distance of 400 yards). A description of the typical downstream drainage path is as follows: • Stormwater from Dowans Creek Road Realigment will either sheet flow to adjacent forest areas where it will naturally disperse,or will be collected and conveyed in drainage ditches. • Drainage ditches will discharge stormwater to adjacent forest areas where it will naturally disperse, or to culverts crossing under Dowans Creek Road Realignment. • Stormwater discharged by cross culverts will be re-dispersed to adjacent forest areas, with the exception of two cross culverts that discharge to Type 5 streams that may intermittently flow to the Bogachiel River. 3. Environmentally Sensitive Areas. a. Description of environmentally sensitive areas that are on or adjacent to the site. There is a 200 acre dormant, deep-seated landslide that extends 750 ft. along the Bogachiel River and encompasses a portion of the road realignment. b. Description of special requirements for working in or near environmentally sensitive areas. A geotechnical report that was prepared for this project concluded that the proposed road realignment will not reactivate the landslide. To the maximum extent feasible,work shall be phased to minimize exposed soil thereby preserving natural vegetation and providing source control. 4. Erosion Problem Areas. Description of potential erosion problems on site in the context of the characteristics of the on-site soils(e.g.,erodibility, settleability, permeability,depth,texture, soil structure). Excavation exposing native soils with high silt content will require temporary stabilization to provide source control of erosion. Silts can be difficult to settle and separate from turbid storm water runoff due to the fine particle nature of silts and the tendency for silts to stay suspended in the stormwater. 5. Construction Phasing. a. Construction sequence • Install temporary erosion control BMPs and flag clearing limits. • Clearing,grading, and surfacing of roadway.

Stormwater Management Unified Development Code Requirement(s): The Jefferson County Unified Development Code, Sections 18.30.060, Grading and excavation standards and 18.30.070,Stormwater Management Standards both set standards for erosion and sedimentation control and stormwater management. The code adopts the requirements set forth by the most current version of the Washington Department of Ecology(DOE), Stormwater Management Manual for Western Washington(SWMMWW). JCPW Findings: SEPA was completed through the Department of Natural Resources. The Washington State Department of Transportation(WSDOT)has developed the Highway Runoff Manual(FIRM). The FIRM is a DOE approved equivalent manual to the SWMMWW which local agencies can use for designing stormwater controls for their local road projects. Local Agencies using federal funds passed through the WSDOT Highways&Local Programs division must meet or exceed the requirements of the FIRM or SWMMWW. The DOE Temporary Erosion& Sediment Control(TESC) elements have been removed from the FIRM and placed into the separate WSDOT,TESC Manual. This project proposes to realign a segment of Dowans Creek Road due to a portion of the existing road being washed out by a landslide adjacent to the Bogachiel River.The proposed road realignment is located approximately 400 feet upslope of the road washout area and will follow approximately 2,300 feet of existing gravel as well as requiring approximately 1,700 feet of new road construction all on DNR state lands ownership.The new road construction will utilize a balanced cut and fill design. The road will be crowned and have an in-sloped ditch.The road width will range from 16 to 24 feet including pullouts. The surfacing will be 6-inches of crushed gravel. • (From the Geotechnical report)The Dowans Creek Road landslide appears to have been initially activated between 1981 and 1985 as the river migrated into the hillslope.At that time,the landslide was approximately 300 feet wide and extended approximately 200 feet upslope. It appears that the Dowans Creek Road was re-routed around the most active portion of the landslide in the early 1990's.As the outer bend of the Bogachiel River continued to migrate downstream and into the hillside,the landslide area progressively expanded to its present size. A portion of the road was lost to the landslide in December 2007 in conjunction with flooding of the Bogachiel River and emergency repairs were conducted shortly thereafter to allow access around the wash out.A small seasonal stream flows into the portion of the landslide that caused the road washout and was likely an important contributing factor that helped to saturate soils and increase pore water pressure in the landslide. The proposal lists the new impervious surface area as 45,654 sf per the HRM definition.Given this criteria, the proponent shall comply with Minimum Requirements#1-#9 of the HRM. To comply with Minimum Requirements#1-#9 the proponent submitted the following documents which together constitute the Stormwater Site Plan:Construction Documents(sheets 1-15 dated Oct.2014), including a TESC Plan and Drainage Details,a Jefferson County Stormwater Site Plan Submittal Template and Stormwater Pollution Prevention Plan(SWPPP)Template and a Geotechnical report dated 8/15/08. The above referenced documents were prepared by the Jefferson County Department of Public Works. The submitted Construction Schedule anticipates work to begin Summer 2015. This project technically creates more than 5000 sf of new pollution generating impervious surface(PGIS) (although it also replaces a similar PGIS area which will be eliminated).It therefore triggers a TDA level assessment of the quantity of PGIS per the HRM.However,given that the entire road realignment is surrounded by extensive forest land which will provide the soil and vegetation characteristics necessary for the removal of pollutants,A TDA level assessment has not been performed.Forest lands adjacent to the project meet the requirements of BMP FC.01 (Natural dispersion areas). Per Section 3-3.5.3 of the HRM, PGIS area that will flow to an existing(pre-project)dispersion area can be subtracted as non-effective PGIS. Therefore no stormwater treatment facilities are proposed. Per both the Soil Survey of Jefferson County and the Natural Resources Conservation Service(see attached), the soils on-site are mapped as Huel(11W),loamy fine sand with a permeability of 6.0-20 inches per hour, Klone(KND)a blend of gravelly silt loamy and cobbly loam with a permeability of 0.6-6.3 inches per hour, and Hoko(HKE)gravelly silt loam with a permeability of<0.06-2.0 inches per hour. In an email dated 7/18/13 Jim Pearson,Jefferson County Development Review Planning Project Coordinator, determined that although the project will disturb more than one acre,since it will not discharge stormwater to surface waters of the state,a DOE NPDES Construction Stormwater General Permit is not required. 411 411 JCPW Comments: JCPW staff met on 10/28/14 and noted the following clarifications: • With regard to both TESC as well as permanent stormwater management,given the potential for both surface and channel erosion due to the project soil types described above,additional channel protection was recommended. V/` • For the same reason,as well as to encourage dispersion(per WSDOT FC.01)outlet protection at all culvert and swale/ditch outlets was also recommended. is • Additionally,silt fence was recommended along the north(downhill)side of all proposed fill slopes and along each side of the two type 5 streams,at approximate stationing 18+14 and 28+34. JCPW Recommendations: V • The proponent shall install the stormwater management facilities and implement the Best Management Practices(BMP's)proposed in the Stormwater Site Plan. V • Before any construction begins on-site,erosion control facilities shall first be installed. V • In accordance with the Jefferson County Unified Development Code, Section 18.30.080(1)(f): Clearing, grading,and construction of roads,bridges,utilities, and stormwater management facilities shall be inspected by JCPW. JCPW staff will be onsite every day throughout construction to ensure that the stormwater facilities are installed per the approved plans.

Comments: V. Environmental Review Project Conditions USFWS BiOP (February 25, 2012) Conditions 1-7: 1) Construction on the segment of road within and adjacent to identified murrelet stand (Station 37 and to the east)may occur only on or after August 14, and during the remainder of the nesting season work that generates noise that could affect murrelets in the stand would be restricted to 2 hours after sunrise to 2 hours before sunset. The activities for which this timing restriction would apply include chainsaw work within 135 feet of the murrelet habitat or heavy equipment within 105 feet of the murrelet habitat. 2) The new route shall be adequately marked prior to felling of trees and/or operating heavy equipment. Old or obsolete marking shall be removed,relevant marking shall be made so that they are highly visible and spaced appropriately, and on-the-ground orientation by WDNR and/or County staff shall be held with fellers and operators to ensure they understand the layout and what is expected. Proper understanding and communications will help minimize inadvertent removal of potential nest trees, trees that provide cover to potential platforms, and addition trees that help ensure stand integrity. No fellers or equipment operators will work on the project until they have completed an on-the—ground orientation with WDNR and/or the county. 3) Only trees within the marked work area shall be felled in preparation for or during road construction. This will minimize the initial loss of potential nest trees. 4) Ensure that contractors employ effective sanitation practices for proper disposal of food and garbage with may otherwise attract corvids and increase the likelihood of predation on nesting murrelets and/their chicks.

An environmental impact statement(EIS)must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal(and to reduce or avoid impacts from the proposal,if it can be done)and to help the agency decide whether an EIS is required. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant,requiring preparation of an EIS. Answer the questions briefly,with the most precise information known,or give the best description you can. You must answer each question accurately and carefully,to the best of your knowledge. In most cases,you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer,or if a question does not apply to your proposal,write"do not know"or"does not apply." Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems,the governmental agencies can assist you. 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. Use of checklist for nonproject proposals: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION,complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS(part D). For nonproject actions,the references in the checklist to the words "project," "applicant,"and"property or site"should be read as"proposal," "proposer,"and"affected geographic area,"respectively. A. BACKGROUND 1. Name of proposed project,if applicable: Dowans Creek Road Easement/Relocation 2. Name of applicant: Mark Thurston Jefferson County Public Works Dept. 623 Sheridan Street Port Townsend, WA 98339 (360)385-9210 4. Date checklist prepared:December 9th,2013 5. Agency requesting checklist:Washington Department of Natural Resources 6. Proposed timing or schedule(including phasing,if applicable): Harvest timber and construct road:August 15—Sept 30,2014 261278 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY 7. Do you have any plans for future additions, expansion,or further activity related to or connected with this proposal? If yes, explain. After construction Jefferson County Public Works would conduct regular on-going road maintenance activities such as road grading and shoulder mowing. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. A Geotechnical Report was prepared for the project by E. Steven Toth, Licensed Engineering Geologist(August 15,2008).(See attached.)The Dowans Creek Road adjacent to the Bogachiel River was damaged by a landslide that was activated by flooding that destabilized the toe of the slope adjacent to the river. The Geotechnical Report determined that the damaged section of the road is located within an approximately 200 acre dormant landslide complex that extends for approximately 750' along the river. The Report determined that it is not feasible to repair the road in its existing location, but that the road could be moved upslope to the proposed location without reactivating the dormant landslide. tUq l ably f h, ,acJ F P 4 RS .)1-t , F Pq 462612_742 The Federal Emergency Management Agency conducted NEPA review of the project and issued a Final Environmental Assessment (March 3, 2013) and a Finding of No Significant Impact (March 25, 2013) (See attached). The EA assessed subjects that are included in SEPA review, but not typically addressed in NEPA, including Energy and Natural Resources,Environmental Health,Land and Shoreline Use,Housing,and Utilities. The project site is occupied marbled murrelet habitat. Murrelets are listed as a threatened species under the Federal Endangered Species Act.The project site is subject to timber harvest restrictions under the DNR's Marbled Murrelet Habitat Conservation Plan. FEMA prepared a Biological Assessment (March 2012) and conducted formal consultation with the US Fish&Wildlife Service.USFWS issued a Biological Opinion(February 25,2013)which determined that a variance to the HCP could be granted to allow the project provided that conservation measures to avoid and minimize effects on murrelets are incorporated and compensatory mitigation is provided. FEMA and USFWS agreed that appropriate mitigation would be the purchase of two 5-acre parcels in the DNR's Dabob Bay Natural Area Preserve that would protect murrelet nesting and foraging habitat. DNR and Jefferson County have approved an Inter-Agency Agreement to fund DNR's purchase of the parcels.The parcels have been purchased. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes,explain. No 10. List any government approvals or permits that will be needed for your proposal,if known. Right-of-way easement and Forest Practices Permit—DNR Stormwater Permit—Jefferson County Department of Community Development Incidental Take Permit 1 I. Give brief,complete description of your proposal,including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) DNR would grant a new easement to Jefferson County who would then relocate a segment of the Dowans Creek County Road adjacent to the Bogachiel River that was severely damaged by a landslide during a flood event in December 2007. A Geotechnical Report (E. Steven Toth, Licensed Engineering Geologist, August 15, 2008) determined that it was not feasible to repair the road in its current location but that it could be moved upslope to the proposed location. Other alternative routes were assessed, but determined not to be feasible. DNR will also grant county road easement on the existing road through Government Lots 11, 12 and, 13 Section 1 township 27 North, Range 13 West,W.M.for which there is no public record of easement. 2 2612762 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY The new alignment would be approximately 200' south of the landslide area. It would be on a 60' wide easement (with limited areas with 75'-80'widths to allow for fill slopes)on land managed by DNR.The new alignment would include 2,270' of existing gravel logging road and 1,720' of new gravel road construction. The existing road has a 14' — 18' width. It would be graded and resurfaced and six 8' wide pullouts would be constructed. The new road would have a 16' width with two 8' wide pullouts. Construction would require 1.25 acres of timber harvest; clearing,grubbing,excavation,and filling; installing 5 culverts;and placing gravel base and crushed surfacing. The county engineering drawings for the project show the length of new construction and reconstruction of existing road. The drawings are included in the Biological Opinion as figures 3 through 7 inclusive. These drawings show the total distance of the proposal to be 3,990 feet. Of this total,2,270 feet is reconstruction of an existing road. The remainder, 1,720 feet, is new construction. The federal documents(FONSI,Biological Opinion, Environmental Assessment and,Biological Assessment)identify the total distance as 3,960 feet. This discrepancy apparently results from the identification,by the federal document author(s),of the length of new construction as being,"...about 1,690 feet..."through"...WDNR-managed land..."(Biological Opinion,page 3, Description). The WDNR-managed parcel referred to is the S1/2SE1/4 Section 1. The 30 feet of new construction not identified in the federal documents is the distance from the north line of the S 1/2SE 1/4 Section 1 to the end of the reconstruction in Government Lot 11 Section 1 (station 32+70). Adding the 30 feet missing from the federal documents to station 32+70 puts the east end of the missing 30 feet at station 33+00 which is 400 feet west of station 37+00(the west edge of the identified murrelet stand(FONSI,condition 1)). 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address,if any,and section,township,and range,if known. If a proposal would occur over a range of area,provide the range or boundaries of the site(s). Provide a legal description,site plan,vicinity map,and topographic map,if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project site is Dowans Creek Road between Mile Posts 0.85 and 1.53 in West Jefferson County, east of Highway 101 and south of the Bogachiel River in the South Half of Section 1,Township 27 North,Range 13 West. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site(circle one): Flat,rolling,hilly,steep slopes,mountainous, other b. What is the steepest slope on the site(approximate percent slope)? Slopes generally range from 10%-30%with the steepest slopes 50%-60%. c.

Klone gravelly silt loam 3 2612 76 TO BE COMPLE t ED BY APPLICANT EVALUATION.FOR AGENCY USE ONLY d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. There is a dormant, 200 acre landslide complex that extends approximately 750' along the Bogachiel River. The landslide that damaged the road was initiated by channel migration that undercut the toe of the slope. The Geotechnical Report for the project determined that the road could be moved upslope to the proposed location without reactivating the dormant landslide. e. Describe the purpose,type,and approximate quantities of any filling or grading proposed. Indicate source of fill. The project will require approximately 3,200 cubic yards of excavation and approximately 3,000 cubic yards of fill to construct the road structure.Fill would be either onsite material or imported material from a commercial pit. f. Could erosion occur as a result of clearing,construction,or use? If so,generally describe. Yes,soils exposed during construction could be subject to erosion. g.About what percent of the site will be covered with impervious surfaces after project construction(for example,asphalt or buildings)? Approximately 25% of the 60' wide easement would be covered by the compacted gravel road surface. This would be less than 1%of the overall DNR parcel. h. Proposed measures to reduce or control erosion,or other impacts to the earth,if any: Public Works would implement a Construction Stormwater Pollution Prevention Plan that is consistent with Minimum Requirement #2 of the Ecology Stormwater Management Manual (2012). The project would be constructed during August and September when precipitation is generally very low. Appropriate construction phase BMPs would be implemented. Prior to the onset of the rainy season, the roadway would be surfaced with crushed gravel and exposed soils would be hydroseeded and mulched. Additional erosion control BMPs such as surface roughening and coir matting would be employed as appropriate to avoid erosion. 2. Air a.

Li Jefferson County Public Works j_=fit COUNTY P. O. Box 2070 "T OP COMMUNITY DEVELOPMENT Port Townsend, WA 98368 Subject: Addendum to 2008 Geotechnical Report for the Dowans Creek Road Realignment Dear Mr. Thurston: The purpose of this letter is to update my previous report titled, "Geotechnical Report for the Dowans Creek Road Realignment, Jefferson County, Washington," and dated August 15, 2008. The geotechnical report was funded by Jefferson County Public Works to investigate a large landslide complex that has impacted the Dowans Creek Road along the Bogachiel River. Jefferson County has proposed relocating the Dowans Creek Road around the active portion of the landslide. The road realignment involves approximately 2,300 feet of existing gravel road on Rayonier Timberlands ownership and approximately 1,700 feet of newly constructed road on Washington Department of Natural Resources ownership. To ensure that the assessment and conclusions from the 2008 geotechnical report are still valid, I reviewed aerial photographs from 2006, 2009, 2011, and 2013 and conducted a site visit on January 28, 2013. The series of aerial photographs shows that Bogachiel River has at least temporarily abandoned an upstream meander bend and now takes a more direct route past the toe of the glaciolacustrine deep-seated landslide (Figures 1-4). The river continues to progressively meander and erode into the floodplain terrace beyond the landslide. The current route of the river has allowed the toe of the landslide to revegetate with young alder; however, the toe of the landslide is still vulnerable to erosion during future shifts in channel location. The site visit also included a review of the proposed new construction on Washington State Department of Natural Resources ownership. The centerline has been flagged and the right- of-way has been staked. No evidence of recent slope movement was observed along the new road alignment. The proposed road alignment does cross the body of an ancient, dormant deep-seated landslide; however, no evidence exists of slope displacement during modern times. The conclusions outlined in the August 15, 2008 report are still valid at the present time.

August 2008 Page iv • • Dowans Creek Road Realignment Geotechnical Report 1.0 Introduction Jefferson County Public Works contracted with E. Steven Toth, Consulting Geomorphologist, to investigate a large landslide complex that is impacting the Dowans Creek Road along the Bogachiel River on the west coast of the Olympic Peninsula, Washington. Mr. Toth is a licensed Engineering Geologist (#1574) in the State of Washington with nearly 20 years of experience investigating unstable slopes in the Pacific Northwest. The project area is located approximately 5 miles south of the City of Forks in Jefferson County, Washington (Figure 1). The Dowans Creek Road is located on the south side of the Bogachiel River and the landslide complex is located in Section 1, Township 27 North, Range 13 West, W.M. and Section 6, Township 27 North, Range 12 West, W.M. (Figure 2). Jefferson County Public Works is proposing to relocate a portion of the Dowans Creek Road around the landslide. The new route will include approximately 2,300 feet of existing gravel road on Rayonier Forest Products ownership and approximately 1,700 feet of newly constructed road on Washington Department of Natural Resources state trust ownership. The scope of work consisted of a reconnaissance-level evaluation of the geology and geomorphology of the landslide and the surrounding terrain to assess the potential for road construction to affect slope stability. A geological reconnaissance survey involves observations of slope characteristics, such as soil type, parent material, gradient, slope form, drainage, and vegetation, with an emphasis on identifying evidence for past slope movement. The results of the field survey are compared with information from regional geology maps, soil surveys, and other documents related to slope conditions. The scope of work also included reviewing the history of channel migration by the Bogachiel River to evaluate the design life of the new road alignment and a delineation of the channel migration zone. Field surveys of the site were conducted in April and May 2008. Subsurface analysis of the geological and hydrological conditions was outside the scope of work. Forest practices rules require Class IV Special review of road construction near unstable slopes and in the ground water recharge areas of glacial deep-seated landslides that could impact public resources or threaten public safetyl. This report is written to fulfill the Washington Forest Practices Rules requirements regarding the evaluation of forest practices on potentially unstable slopes and follows the guidelines for geotechnical reports provided in Section 16 of the Forest Practices Board Manual regarding unstable slopes2. The report describes potentially unstable slopes or landforms and analyzes the likelihood that the proposed forest practices will cause or contribute to further movement. In addition, the report evaluates the likelihood of delivering sediment or debris to any public resources or in a manner that would threaten public safety. Finally, specific actions are recommended to mitigate for any identified hazards and risks.

The Bogachiel River drains from mountainous terrain in Olympic National Park flowing for about 25 miles through a narrow and deep valley. The river then flows through a broad valley in the coastal foothills for another 22 miles until its confluence with the Quillayute River. The landslide complex is located on the south valley wall of the Bogachiel River between River Mile 18 and 19 (Figure 3). The site generally has a north-facing aspect and ranges from about 260 feet in elevation at the river to approximately 380 feet in elevation at the start of proposed new road construction. The new road alignment right of way supports primarily mature conifer, the majority of which appear to be about 70 years old. Previous timber harvesting of the site likely occurred in the late 1930s. The primary land use in the area is commercial forestry, although there are several rural residential lots at the end of Dowans Creek Road and recreational use in the nearby Olympic National Forest and National Park. 2.1 Water and Fish Resources The Bogachiel River has a basin area of approximately 111 square miles, not including the Calawah River basin. The average annual rainfall ranges from 110 to 120 inches in the project area, but can approach 200 inches in the headwaters of the basin (Sumioka et al. 1998). Runoff in the basin is primarily from rainfall, with little significant accumulation of snowpack. The Bogachiel River is considered a water of statewide significance (Type S) and supports multiple anadromous and resident salmonid species. Anadromous salmonids in the stream network include chinook (Oncorhynchus tshawytscha), coho (Oncorhynchus kisutch), chum (Oncorhynchus keta), steelhead (Oncorhynchus mykiss), cutthroat (Oncorhynchus clarki), and bull trout (Salvelinus confluentus). The valley bottom contains extensive floodplains dominated by hardwoods and to a much lesser extent conifer. 2.2 Geology The Olympic Mountains are part of the Cascadia Wedge formed by subduction of the Juan de Fuca Plate beneath North America (Figure 4). The toe of the Cascadia Wedge, known as the Olympic Subduction Complex, forms the core of the Olympic Mountains (Stewart and Brandon 2002). The Olympic Mountains are uplifting at rates of approximately one millimeter per year (Pazzaglia and Brandon 2001) and evidence suggests that uplift has actively occurred for at least the past 15 million years, since the late Miocene (Brandon et al. 1998). During this time, coastal areas of the Olympic Peninsula appear to have remained at or near present day sea level (Pazzaglia and Brandon 2001). Uplift of the core rocks of the Olympic Mountains is accommodated along a complex fault system that nearly encircles the Olympic Peninsula. The fault system also represents a boundary August 2008 Page 4 i 0 Dowans Creek Road Realignment Geotechnical Report y ` � —`--.�....__ ��-• t� � � „\\• `_ , s __ -_-= Lam \ zr i !F tA►axv- y"1 L11r .' - % -'': y ^ ''_ i._ f. , acne - `' ._ _ ___ ti trim a_ anrF3 arljL g. .... _v —.� _ i A mr • ' k 1 "E, t. ter Er' I_ . 1 y 2 l .i c;OAU `� ` t J' i jtrr f l i % 3A�T,69 S 7 85 �1 o s Mill TN go 6 oll rt-i 1 _ 506 IOW METE 1S ......_ — —.

The project area was not affected by the Cordilleran ice sheet, whose Figure 4. Map of the Cascadia Wedge including the terminus is approximately five uplifted Olympic Subduction Complex and the Coast miles to the north, but was Range Terrane (from Stewart and Brandon 2002). overridden by alpine glaciers approximately 200,000 years ago. The surrounding area is mapped as pre-Fraser alpine glacial outwash (Qapo) and alpine glacial drift (Qapw(2)) that were deposited from 55,000 to 110,000 years ago. The glacial deposits are likely underlain by marine sedimentary rocks consisting of sandstone and thinly bedded siltstone, shale, and slate that outcrop at the Dowans Creek confluence and north of the Bogachiel River. Several large deep-seated landslide complexes have been mapped in the glacial deposits along the Bogachiel River. Gerstel (1999) identified the 282-acre landslide in the project area as occurring in older alpine glaciofluvial/glaciolacustrine terrace deposits. Field investigations and review of the aerial photographs indicated that the valley bottom north of Dowans Creek Road in Section 6 consists of alluvium on the floodplain of the Bogachiel River. The outline of the ancient deep-seated landslide in Figure 2 portrays the boundaries of this mass wasting feature more accurately.

August 2008 Page 7 • • Dowans Creek Road Realignment Geotechnical Report 2.3 Soils The area of the Dowans Creek Road landslide and the proposed road realignment are mapped as Klone soil (Figure 6). The well drained Klone soil occurs in glacial outwash on slopes from 35 to 90 percent gradient. The very gravelly loam soil contains from 40 to 60 percent rock fragments. Soil depths are typically greater than 60 inches. The Klone soil type has a medium to high mass wasting potential rating and a severe road construction hazard rating. The valley bottom soil types are mapped as silty Udifluvent soils on the active floodplain and Hoko soils on fluvial and glacial terraces adjacent to the river (WDNR 1978). The gravelly silt loam Hoko soil formed on glacial till with slope gradients of 5 to 20 percent. The soil consists of 30 to 40 percent rock fragments and often has a restrictive till substratum at 20 to 40 inches in soil depth. This moderately well drained soil is generally stable with a low erosion potential. Soil pits were dug at various locations to assess and verify general soil conditions. Detailed soil logs and laboratory testing of soil characteristics were beyond the scope of this reconnaissance- level assessment. Field investigations, however, did indicate that the area mapped as the Hoh soil type occurs on the modern floodplain and is not derived from glacial deposits. These soils would be more accurately described by the Udifluvent soil type. 3.0 Background on Deep-Seated Landslides and Groundwater Recharge Deep-seated landslides are the result of deep, rotational failures triggered by the buildup of pore water pressure in a mechanically weak or fractured rock or soil mass. The slide moves along a surface of rupture that is curved and concave (Cruden and Vanes 1997). Slumping involves the downward movement and backward rotation of a block or group of blocks. There are three main parts of a deep-seated landslide: the scarp, the body, and the toe (Figure 7; Varnes 1978). The main scarp and flanks are a steep, arc-shaped surface along the upper edges of the landslide caused by movement of displaced material and represents the upper rupture surface. Other minor scarps that are produced by the differential movement of displaced material may be present within the body of the landslide. The body of the landslide consists of displaced material that overlies the surface of rupture between the main scarp and the toe of the feature. The toe of the landslide is typically a curved margin of displaced material most distant from the main scarp. The body and toe often have hummocky terrain due to the differential movement of slump blocks. The flow path of streams and groundwater are often altered due to the differential movement of landslide blocks. The groundwater recharge area of a deep-seated landslide is the topographic basin upslope of the displaced material that contributes subsurface water to the landslide.

Block diagram of idealized deep-seated landslide (from Varnes 1978) water is generally a function of the amount of precipitation minus the evaporation of water from plant surfaces and the transpiration of soil moisture through vegetation. Water can be a significant factor in the movement and activity of deep-seated landslides, so road construction or vegetation removal that alters the amount or timing of water infiltration may be an important factor. Increasing the pore water pressure and causing wider fluctuations in groundwater levels can decrease the shear strength of the soil(Iverson 2000). Even with potential increases in soil moisture from altering drainage patterns or reducing evapotranspiration, subsurface flow paths can be complex and the amount of groundwater reaching the surface of rupture may be independent of infiltration rates. Water infiltration can range widely depending on parent material, stratigraphy, and soil texture (Bauer and Mastin 1997). The removal of vegetation for road construction can also influence slope stability by reducing soil cohesion as root systems decay. Root reinforcement of the soil mantle generally does not play a role in the stability of deep-seated landslides because the rupture surface is located below the rooting zone of trees. These roots can be important, however, in increasing slope stability along steep scarp slopes that are susceptible to translational landslides. Tree roots provide tensile reinforcement to the soil mass and can buttress the upslope soil mantle (Gray and Megahan August 2008 Page 10 • • Dowans Creek Road Realignment Geotechnical Report 1981). The root systems of trees also intertwine to form a lateral network of soil reinforcement (Sidle et al. 1985). Landslides tend to occur in areas of reduced root strength (Roering et al. 2003). At present, no standard methodology exists for evaluating the effects of road construction and timber harvest on the movement of deep-seated landslides. Therefore, the following evaluation of the deep-seated landslides in the project area will focus on the history of slope movement, potential changes in runoff from road construction in the landslide body, and the stratigraphy of the landslide relative to potential water infiltration. 4.0 Assessment of Deep-Seated Landslide Activity Both the larger deep-seated landslide complex and the rotational landslide along Dowans Creek Road were assessed for evidence of past landslide activity. The assessment relied on the historical series of aerial photographs and field observations of slope characteristics and areas of active slope movement. Table 1 lists the series of historical aerial photographs consulted for this geotechnical evaluation. Aerial photographs ranged in scale from approximately 1:12,000 to 1:15,000.

Aerial photographs used to evaluate the Dowans Creek Road landslide. 4.1 Deep-Seated Landslide Complex The large deep-seated landslide complex is approximately 200 acres in area (Figure 2). The landslide originated in glacial outwash deposits and ranges in elevation from about 240 feet at the river bottom to approximately 540 feet above sea level at the top of the main scarp. The August 2008 Page 11 • Dowans Creek Road Realignment Geotechnical Report main scarp of the deep-seated landslide is visible in the aerial photographs as an arcuate bluff north of the forest road that crosses through Sections 7 and 12 (Figures 2 and 3). The benched topography and sag ponds from the rotational movement of slump blocks below the main scarp are also apparent on the 1990 photographs following a recent timber harvest. Field observations along the main scarp of the large deep-seated landslide complex identified several recent landslides from the steep bluffs. The bluffs range from 50 to 100 feet in height with a large apron of colluvium at the base of the slope. The steep bluffs are prone to mass wasting due to slope gradients greater than 80 percent, weakly cemented glacial material, and ample groundwater flow from glacial outwash deposits within the groundwater recharge area. The landslides from the bluff are classified primarily as translational slides that rupture along a largely planar surface, although some small rotational slumps were also observed (Varnes 1978). Most of the translational landslides deposit onto the series of benches formed by individual slump blocks within the deep-seated landslide complex, although where sufficient water has accumulated, the landslides can become debris flows that may travel several thousand feet to Dowans Creek Road or the Bogachiel River. Several sag ponds and wetland areas that have formed on benches behind the slump blocks were also observed. Overall, field observations and a review of historical aerial photographs indicate that the large deep-seated landslide is currently inactive, despite recent slope movement at the toe of the feature and translational landslides from the main scarp. The slump blocks within the body of the landslide appear stable with evidence of old-growth stumps throughout the body of the landslide complex. No evidence of recent movement, such as tension cracks, displacement of slump blocks, or recently exposed soil was observed within the body of the landslide. The lack of evidence for any deep-seated slope movement indicates that the landslide is a dormant or relict feature that was likely initiated several thousand years ago. 4.2 Dowans Creek Road Landslide The Dowans Creek Road landslide is located at the toe of the dormant deep-seated landslide complex and extends for approximately 750 feet along the Bogachiel River. The landslide appears to have been initially activated between 1981 and 1985 as the river migrated into the hillslope. At that time, the landslide was approximately 300 feet wide and extended approximately 200 feet upslope. It appears that the Dowans Creek Road was re-routed around the most active portion of the landslide in the early 1990's. As the outer bend of the Bogachiel River continued to migrate downstream and into the hillside, the landslide area progressively expanded to its present size. A portion of the road was lost to the landslide in December 2007 in conjunction with flooding of the Bogachiel River and emergency repairs were conducted shortly thereafter to allow access around the wash out (Figure 8). A small seasonal stream flows into the portion of the landslide that caused the road washout and was likely an important contributing factor that helped to saturate soils and increase pore water pressure in the landslide.

The fact that the landslide was initiated coincident :•` '•:'- X11`;% with the channel migrating to this portion of the hillside indicates that the underlying cause of the landslide is undercutting of the landslide toe by the Bogachiel River. Many similar rotational landslides in glaciolacustrine sediments have been observed �, ,„, s along the Bogachiel River where the river abuts the '` valley wall (Herrera Environmental Consultants, Inc. 2004). While the landslide feature may have already existed in a dormant state, the river likely removed a critical amount of material that was buttressing the glacial sediments. The removal of : ..-.,,,,,, . ., 4.,: ; material at the toe of the landslide has caused the "' 1 = ► rotational failure of several slump blocks within the > . . larger feature. In addition, a number of springs � - '` , � flow out of the main scarp area, saturating the weakly cemented glaciolacustrine sediments. The , saturated silts and clays slough off or flow down the _ _ body of the landslide as a slurry (Figure 9).

Earthflow within Dowans well as the flow of saturated material. Creek Road landslide. August 2008 Page 13 • • Dowans Creek Road Realignment Geotechnical Report Figure 10 shows a field developed cross-sectional profile of the landslide slope. The most active portion of the landslide extends approximately 200 feet upslope with an average slope gradient of approximately 60 percent. The scarp of the most active slump blocks are generally greater than 100 percent gradient and the displacement of the slump blocks generally ranges from 4 to 10 feet. Displacement of slump blocks was observed an additional 200 feet above the most active portion of the landslide exposing the soil mantle and causing jack-strawed trees. Soil displacement has occurred up to the base of the Dowans Creek Road prism at this location. The deep-seated rotational landslide occurs in glaciolacustrine deposits that consist primarily of soft, lean clay (CL) with low dry strength, no dilatancy, and medium toughness and plasticity. While the gray clay deposits are generally homogeneous, some stratification was observed with lenses of silt or fine sand. Portions of the landslide also contain gray, stratified silt (ML) with low dry strength, slow dilatancy, and low toughness and plasticity. The glaciolacustrine deposits are overlain by glacial outwash that has formed a weakly cemented, well graded sand with gravel (SW). A typical sample consists of approximately 60 percent coarse, subrounded, brown sand and 40 percent hard, subrounded to rounded, brown and gray gravel. The glacial outwash deposits are typically covered by less than 6 inches of organic duff material.

The new road construction will utilize a balanced cut and fill design. The road will be crowned and have an in-sloped ditch. The road width will range from 12 to 16 feet including pullouts. The surfacing will be a 4- to 6-inch lift of crushed gravel. The new road construction is located primarily on benches formed by slump blocks from the ancient landslide complex. The side slopes generally range from 10 to 30 percent gradient, although some portions of the road traverse 50 to 60 percent slopes. The road crosses the head of a small stream basin that eventually flows into the road washout area, but no evidence of surface flow was observed at the road crossing. A small wetland sag pond is located upslope of the road crossing and likely feeds the stream through subsurface flow. The road design calls for a 48-inch diameter pipe at this location. Two 24-inch cross drains are also included near the beginning and end of the road. The new road is located approximately 400 feet upslope of the road washout area. No evidence of slope movement was observed for 200 feet on either side of the road centerline. Minor soil creep was noted on steeper slopes and along an old cat road in the area. The combination of moderate slope gradients and unconsolidated glacial sediments with a high infiltration rate limit the potential for slope instability. The one area of new road construction located in closer proximity to recent slope movement is at the east end of the proposed road construction and its junction with the existing Dowans Creek Road. The new road construction ends at a small stream crossing that flows just east of the Dowans Creek Road landslide. Approximately 150 feet northwest of the road junction, soil displacement of one to three feet was noted from a slump block just below the road prism. The relatively flat area between the road junction and the area of soil displacement consists of a forested wetland with approximately 15 year old red alder (Alnus rubra). The abandoned Dowans Creek Road alignment is still intact in this area and showed little evidence of recent slope movement. While the new road is generally located a significant distance from any recent slope movement, future slump block movement associated with the road washout could propagate upslope for some distance. In order to better estimate the risk of future slope movement in the vicinity of the new road, a more detailed analysis of channel migration rates was undertaken. August 2008 Page 15 • • Dowans Creek Road Realignment Geotechnical Report 6.0 Channel Migration Zone Definition The Washington Forest Practices Rules define a channel migration zone as follows: Channel migration zone (CMZ) means the area where the active channel of a stream is prone to move and this results in a potential near-term loss of riparian function and associated habitat adjacent to the stream, except as modified by a permanent levee or dike. For this purpose, near-term means the time scale required to grow a mature forest. (WAC 222-16) Section 2 of the Forest Practices Board Manual provides additional guidance for identifying and delineating CMZs. The methodology for delineating CMZs consists of identifying four potential zones along the valley bottom that collectively define the boundaries of the CMZ3. 1. The historical migration zone (HMZ) —The sum of all active channels over the historical period (post-1900). 2. The avulsion hazard zone (AHZ) — The area not included in the HMZ where the channel is prone to move by avulsion and if not protected would result in a potential near-term loss of riparian function and associated habitat adjacent to the stream. 3. The erosion hazard area (EHA) — The area not included in the HMZ where bank erosion from stream flow can result in a potential near-term loss of riparian function and associated habitat adjacent to the stream. 4. The disconnected migration area (DMA) —The portion of the CMZ behind a permanently maintained dike or levee. The Board Manual guidance provides the following criteria for erosion hazard areas: Establishing an erosion hazard area is necessary for those situations where measurable undercutting or erosion on the order of feet per year or per flood event is currently taking place....However, the CMZ will not extend further than the base of the valley hillslope or other such geologic controls to lateral channel movement. The area to be included in the erosion hazard area can be calculated by averaging the historical erosion rate along the entire length of the channel segment or by calculating the erosion rate at a specific location where erosion may be concentrated. 3 Washington Forest Practices Board Manual.

August 2008 Page 16 • • Dowans Creek Road Realignment Geotechnical Report 7.0 Channel Migration of the Bogachiel River This reach of the Bogachiel River has been actively migrating across its floodplain and into adjacent glacial valley terraces for thousands of years. Many floodplain features, such as wall- based side channels and oxbow lakes, may represent channel locations from a different climatic and sedimentation regime. This assessment of channel migration focuses on the more recent history of channel migration and relies primarily on using the historical aerial photographs to identify past channel locations. These photographs coupled with field observations also provide insight into historical and future channel patterns and bank erosion rates. This information is then used to help identify the various zones of channel movement that collectively delineate the channel migration zone. 7.1 Historical Channel Locations To illustrate the amount of channel migration along the river, the historical series of aerial photographs were digitally transformed to the scale of the 2006 orthophoto (Figure 11). Fixed points, such as roads and buildings, were used to accurately overlay the photographs. The channel location was defined as the unvegetated region in the valley bottom and, where discernible, includes recently vegetated bars and side channel areas. While the changes in channel location are generally accurate, some minor differences can be attributed to changes in canopy cover over time, the quality and scale of the air photos, and errors in rectifying the photos. The 1891 General Land Office survey map was also consulted to assess longer term channel migration (Figure 12). However, the maps could not be easily rectified to the scale of the aerial photographs because of changes to the surveyed section boundaries. The map does indicate that the current channel location has not changed substantially in Sections 1 and 6 even with the greater degree of channel meandering observable in the aerial photographs.

The meander bends have been growing and shifting with two primary types of movement: 1) translation and 2) extension. Translational movement is when the meander bend shifts in position downstream without altering its basic shape. Extension is when the meander bend moves predominantly in the lateral direction increasing its amplitude and path length (Knighton 1998). Significant bank erosion can be expected along the outer edge of these meander bends as they continue to erode unconsolidated glacial sediments or occupy low elevation floodplain areas. No significant channel avulsions took place during the past 50 years, although a side channel on the south side of the river widened considerably between 2003 and 2006. This side channel has a substantial accumulation of large wood at its inlet, which helps to deflect flow into this channel. As the amplitude of this meander bend continues to grow and tighten (between bank erosion points A and C), the river will eventually jump across the floodplain with a chute or neck cutoff channel. The location of the cutoff channel is difficult to predict, but this relatively low elevation floodplain area is at high risk for future channel avulsion. 7.3 Bank Erosion Rates Bank erosion rates were measured at the outer edge of three meander bends (Figure 11). The distan ce of eroded bank was measured perpendicular to the meander bend axis and divided by August 2008 Page 19 • • Dowans Creek Road Realignment Geotechnical Report the number of years between aerial photographs. The results of the bank erosion measurements are presented in Table 2. Bank Erosion Site A experienced the greatest amount of erosion with approximately 1,500 feet over the past 56 years. The high rate of erosion, averaging 27 feet per year is largely attributable to the low elevation floodplain and unconsolidated alluvium that provides little resistance to channel migration. Bank Erosion Site B eroded 400 feet between 1950 and 1962 and eroded another 450 feet in the following 42 years. The high intial erosion rate likely reflects channel migration across the floodplain, while the subsequent lower rate reflects erosion into a 30-to 50- foot high glacial outwash terrace on the north side of the river. The measurements from Bank Erosion Site C provide an estimate for the rate of erosion along the Dowans Creek Road landslide. The overall bank erosion rate since 1950 has been about 8 feet per year, but this also represents migration across the floodplain. Calculating the bank erosion rate since 1985 when the Bogachiel River migrated to the landslide toe, the channel has eroded approximately 100 feet into the Dowans Creek Road landslide or about 5 feet per year.

August 2008 Page 20 • • Dowans Creek Road Realignment Geotechnical Report 7.4 Channel Migration Zone Figure 13 shows the delineation of the channel migration zone on the south side of the Bogachiel River based on the historical analysis of aerial photographs and field observations. The historical migration zone is fairly well defined by channel locations across the air photo record. While the Bogachiel River has migrated predominantly as a result of channel meandering and bank erosion processes, the potential for channel avulsion appears high. Recent floods appear to have reactivated an old side channel in the southwest corner of Section 6. Since the main channel has not avulsed into this side channel, this area of the floodplain was considered part of the avulsion hazard zone. The floodplain in Sections 1 and 6 is generally at or a few feet above the bankfull elevation and is it a high risk for future channel avulsion. The floodplain area includes a number of residences north of Dowans Creek Road. Dowans Creek Road in Section 6 is located in the avulsion hazard zone as well, but generally forms the boundary between the floodplain and the adjacent uplands. The Bogachiel River has shown an ability to erode substantial amounts of high glacial terraces. The north side of the river has eroded a significant length of the bank forming a nearly vertical 30- to 50-foot wall of glacial outwash material. The river has also eroded a significant amount into the glaciolacustrine deposits on the south side of the river initiating the large landslide along Dowans Creek Road. However, the landslide does form a hillslope valley wall with over 100 feet of relief and technically may not represent a true erosion hazard area as part of the channel migration zone. The landslide would be addressed, though, as a slope stability issue in forest practices rules requiring Class IV Special review of any activities in the area. Therefore, an erosion hazard area was not specifically delineated on the south side of the river. One area of interest on the south side of the river immediately east of the Dowans Creek Road landslide has not been subject to any significant channel migration or bank erosion. No significant change in channel location was noted over the past 60 years, despite being at the outer edge of a meander bend during most of this time period (Figure 11). Field observations indicate that the river bank at this location is 10 to 15 feet high and consists primarily of cobble and boulder deposits. Large boulders are also prevalent in the river substrate. It appears that this portion of the ancient landslide deposit is well armored by the boulder lag deposits and, therefore, not as prone to bank erosion and future channel migration. In all likelihood, this hard point along the channel will limit the potential for eastward expansion of the Dowans Creek Road landslide. Given the westward trend in channel migration at Bank Erosion Site C and the bank armoring from the boulder lag deposits, it appears unlikely that the eastern end of the proposed road realignment will be subject to significant slope movement in the near future.

(1) In order to determine whether such forest practices are likely to have a probable significant adverse impact, and therefore require an environmental impact statement, the applicant must submit the following additional information, prepared by a qualified expert. The expert must describe the potentially unstable landforms in and around the application site and analyze: (a) The likelihood that the proposed forest practices will cause movement on the potentially unstable slopes or landforms, or contribute to further movement of a potentially unstable slope or landform; The proposed realignment of the Dowans Creek Road along the body of an ancient deep-seated landslide has a low likelihood of reactivating the feature. Past timber harvest and cat road construction on the landslide body has not contributed to slope movement. (b) The likelihood of delivery of sediment or debris to any public resources or in a manner that would threaten public safety;and The proposed realignment of the Dowans Creek Road is unlikely to deliver sediment or debris to public resources and should diminish the threat to public safety by moving the road away from active slope movement associated with the Dowans Creek Road landslide. (c)Any possible mitigation for the identified hazard and risks: The proposed road construction will meet or exceed the requirements of the forest practices rules. The road has been designed to minimize road cuts that could destabilize slump blocks. Drainage from the road will be carefully dispersed to maintain natural patterns of groundwater movement and avoid concentrating additional water into the stream. 9.0 Limitations The conclusions presented in this report are based on a limited investigation of site conditions, as they existed at the time of our field visits. Subsurface explorations could not be performed, and vegetation and topography limited our observations. It is not possible to fully define the geological conditions of the site based on this limited investigation; however, the work was done in accordance with generally accepted geological practices. The evaluation of slope stability does not include any assessment of seismically-induced hazards. This report is for the sole use of the client on this project and may not be relied upon by other parties. If there is a substantial lapse of time between the submission of this report and the start of work, or if conditions have changed due to natural causes or work at or adjacent to the site, we recommend that this report be reviewed to determine the applicability of the conclusions and recommendations. No other warranty, expressed or implied, is made. August 2008 Page 23 • Dowans Creek Road Realignment Geotechnical Report 10.0 References Badger, T.C. 2007.
