The overall project is proposed by the Western Federal Lands Highway Division (WFLHD) of the Federal Highway Administration (FHWA). The proposal will implement bank stabilization, replace Tower Creek Bridge, and replace Canyon Creek culvert with a bridge along UHHR located in Jefferson County, Washington. Work will occur between milepost 3.52 and 10.27. The UHRR is an 18-mile road that extends east from Highway 101 along the north side of the Hoh River and ends in Olympic National Park (ONP). Jefferson County owns and maintains the 12 westernmost miles of the road and ONP maintains the remaining 6 miles within the park. The proposed UHRR Project (project) study area covers five impact sites and two mitigation sites for the project (Appendix A: Figures 1 and 2). These were specified in the project statement of work as follows:  Site C1, Milepost 3.52 to 4.0 – Implement bank stabilization  Site C2, Milepost 4.0 to 4.49 – Implement bank stabilization  Site C3, Milepost 7.3 – Replace Tower Creek Bridge  Site C4, Milepost 7.3 to 7.93 – Implement bank stabilization  Site C5 Milepost 10.17 to 10.27 – Replace Canyon Creek culvert with a bridge  Site M1, Milepost 7.28 – Mitigation  Site M2, Milepost 9.76 to 9.83 – Potential Mitigation Mileposts provided above are approximate. The individual site study areas were mapped by David Evans and Associates, Inc. (DEA) using Geographic Information System (GIS) software and hand markup maps provided by FHWA. Site study area mapping was confirmed by FHWA and are shown in the Wetland and Stream figures provided in Appendix: A. The Hoh River is eroding away the riverbank and undermining sections of UHRR. FHWA is studying and designing options to stabilize the banks along the river and improve overpasses of several tributaries. This wetland delineation addendum supplements the UHRR Wetland Delineation Report (DEA 2015) and is intended to support related planning, permitting, and design efforts. Upper Hoh River Road Project July 2017 Wetland Delineation Report - Addendum 1 page 2 Figure 1. Project Location Upper Hoh River Road Project July 2017 Wetland Delineation Report - Addendum 1 page 3 2 PROJECT DESCRIPTION WFLHD, in partnership with Jefferson County, plans to construct bank stabilization and bridge and culvert improvements in six locations along UHRR. The general project area extends from mile post (MP) 3.6 to MP 10.2 including areas north and south of the road and the adjacent northern (right) bank and channel of the Hoh River. The UHRR is located in western Jefferson County, Washington, between U.S. Highway 101 (US 101) and the Hoh Rain Forest Visitor Center. The road is used to access ONP and private properties along the road. The road was built in the 1930s, when the park was established, and is the primary western access to the park. The UHRR extends in a generally east-west direction north of and in many places adjacent to the Hoh River, an approximately 56-mile-long river originating from glaciers on Mount Olympus and flowing through the Olympic Mountains, foothills, and emptying into the Pacific Ocean at the Hoh Indian Reservation. The Hoh River valley is relatively flat and broad with a complex channel migration zone that supports a braided river channel, and a wide variety of gravel bars, side channels, and backwater areas. The Hoh River is also characterized by a wide range of seasonal flow rates, with recorded annual peak flows of more than 60,000 cubic feet per second. The road varies in proximity to the Hoh River and in certain areas is within approximately 5 feet of the river embankment. This has resulted in unstable banks and slides during high water or storm events. WFLHD and the County have constructed several bank stabilization projects in recent years along the road in order to prevent road closures due to loss of the roadbed or unstable slopes. WFLHD chose the locations for the proposed project as they had the highest risk of impending failure based on the Upper Hoh River Bank Failure Risk Reduction Study (WFLHD 2013). Without the proposed project, emergency repairs along the UHRR would be regularly required. The proposed project implements cost-effective, long-term bank stabilization solutions at three locations along the UHRR. The roadway at these sites is at risk of washing away in the event of a large flood. The purpose of the proposed bank stabilization improvements is to eliminate or substantially reduce this risk at these three locations, and to assure safe and consistent access to residents, businesses, and ONP visitors via the UHRR. The project will also replace or improve three existing bridge or culvert locations, the intent of which is also to assure safe and consistent access to residents, business, and ONP visitors via the UHRR. 3 METHODS DEA performed field visits to the study area in April 2017 to delineate wetland boundaries, mark stream ordinary high water mark (OHWM), and document existing habitat conditions and wildlife use for areas defined for this addendum. Wetlands were identified and delineated using the routine approach described in the Wetland Delineation Manual (Environmental Lab 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (U.S. Army Corps of Engineers [Corps] 2010). Upper Hoh River Road Project July 2017 Wetland Delineation Report - Addendum 1 page 4 Data plots were sampled that identify the presence/absence of wetland indicators (hydrophytic vegetation, hydric soils, and wetland hydrology). Hydrophytic vegetation was determined to be present when dominant cover of plants observed (greater than 50 percent) had an indicator status of facultative (FAC), facultative wetland (FACW), or obligate wetland (OBL) (Lichvar 2012). Plant species in the study area were identified according to Cooke (1997), Pojar and MacKinnon (1994), and Hitchcock and Cronquist (1973), but updated nomenclature was used where known. Hydric soils were determined based on field indicators such as chroma color, redoximorphic features, and organic content (USDA and NRCS 2017). Evidence of wetland hydrology was based on observations of surface water, indicators of recent inundation, indicators of soil saturation, and from other site conditions (Corps 2010). If the three criteria were present, a wetland determination was made. If one or more of the criteria were absent, the area was designated non-wetland unless determined to be a problem area or atypical situation according to the methodologies (Corps 2010). Wetlands were classified using the U.S. Fish and Wildlife Service wetland classification system (Cowardin et al. 1979). Wetlands were rated and functions/values were assessed using the Washington State Department of Ecology (Ecology), Washington State Rating System for Western Washington (Hruby 2014). This rating system is function-based and differentiates wetlands based on their sensitivity to disturbance, their significance and rarity, the ability to replace them, and the functions they provide. The Hydrogeomorphic (HGM) classes are defined as part of the Ecology rating system (Hruby 2014). Where wetlands are sufficiently similar, a single rating form was completed for multiple wetlands. Wetland boundaries and data plot locations were mapped and subsequently surveyed using a GPS unit. All wetland boundaries, classifications, and assigned buffer widths are subject to verification by regulator agencies. Streams and their OHWM are defined by both the Corps and Ecology. The Corps (2014) guidance defines the OHWM as “that line on the shore established by the fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas.” Ecology’s guidance (Olson and Stockdale 2010) defines the OHWM for state waters. Typical characteristics used to identify the OHWM (Corps 2005) include the following physical characteristics are used when making an OHWM determination, to the extent that they can be identified and are deemed reasonably reliable:  Natural line impressed on the bank  Shelving changes in the character of soil  Destruction of terrestrial vegetation  Presence of litter and debris wracking  Vegetation matted down, bent, or absent  Sediment sorting  Leaf litter disturbed or washed away Upper Hoh River Road Project July 2017 Wetland Delineation Report - Addendum 1 page 5  Scour  Deposition  Multiple observed flow events  Bed and banks  Water staining  Change in plant community Ditches may also be considered jurisdictional when they transport relatively permanent flow (continuous flow for at least three months) directly or indirectly into waters of the United States. All ditches within the study area were reviewed to determine if they meet the U.S. Environmental Protection Agency (EPA) and Corps guidance (EPA and Corps 2008) for being jurisdictional waters. In most situations, it is not possible to document whether a ditch or channel within the project area has relatively permanent flows. The presence of an OHWM should be used as a baseline to establish the potential of relatively permanent flows. The OHWM and relatively permanent flow can be indicated by the following physical characteristics: The following additional characteristics were used to establish potential relatively permanent flow in ditches:  Presence of a defined channel with bed and bank  Areas exhibiting scour marks  Debris wracks  Shelving  Water staining  Areas of flowing or standing water  Clear areas of gravel with no vegetation In several locations, a new OHWM was determined that reflects a significant amount of bank erosion since the original field work in 2015. 4 RESULTS 4.1 Background The planning for this project has required the addition of areas that were not considered in the initial wetland survey (DEA 2015). Wetlands, streams and ditches in these additional areas are described below. Table 1 includes all features identified for the project (wetlands and streams from the 2015 report and this addendum). . 4.2 Wetlands A total of nine additional wetlands were identified and 3 wetland boundaries were extended in the Project area. These wetlands are in addition to the 10 wetlands identified in 2015 (DEA 2015). The wetlands not identified and described in this addendum are fully described in the original wetland Upper Hoh River Road Project July 2017 Wetland Delineation Report - Addendum 1 page 6 delineation report (DEA 2015). Wetland were identified in sites C1, C2, M1, and M2. Wetlands with sufficient similarities were rating together on a rating form. Wetland naming nomenclature in this report were named sequentially from W1 to W12. Wetlands identified in the original report (DEA 2015) used a numbering system that includes the type of aquatic feature (W) for a wetland and (S) for a stream, a site designation (i.e. 1 to 5), and an alpha designation (for example WC1-A). Where the two wetland delineations overlap, both names were included in Tables 1 and 2. Wetlands identified and described in this report slope seep systems except for two depressional wetlands at site M1. The wetlands are forested with evergreen trees. The rating for the wetlands are generally Category III except for the depressional wetlands that have increased water quality and hydrologic functions, which are Category II systems. A detailed comparison of identified wetlands is shown in Table 1. Each individual wetland is detailed in Table 2. Data sheets and rating sheets for all wetlands are in Appendix B and Appendix C. Detailed summaries for each of the described wetlands are included in Table 2. Table 1.

Upper Hoh River Road Project July 2017 Wetland Delineation Report - Addendum 1 page 19 4.3 Streams A total of 12 additional streams were confirmed in the Project area. These streams include S8 through S18 and Willoughby Creek. Eight streams are fully described in the original wetland report (DEA 2015). Streams address in this addendum and basic characteristics are shown in Table 3. The streams are organized by the study area sites. Streams identified in the 2015 report were not re-evaluated in this addendum. Detailed descriptions of the streams in the addendum are included in Table 4. Most of the streams are high gradient valley wall tributaries that drain to culverts on the north side of UHRR and then into culverts that drain almost directly to the Hoh River. Stream naming nomenclature in this report were named sequentially from S8 to W18. Streams identified in the original report (DEA 2015) used a numbering system that includes the type of aquatic feature (S) for a stream, a site designation (i.e. 1 to 5), and an alpha designation (for example WC1-A). Where the two wetland delineations overlap, both names were included in Tables 1 and 2. Table 3.
