The Watershed Company Reference Number: 131113 Dear Rebecca: We have prepared the following “No Effect” letter report summarizing effects evaluations for species listed under the federal Endangered Species Act with regard to the proposed Thunder Hills Sewer Interceptor Rehabilitation in Renton. This assessment has been prepared to document potential project effects on species currently listed by the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) under the Endangered Species Act (ESA). It also evaluates Essential Fish Habitat (EFH) as indicated in the Magnuson- Stevens Fisheries Conservation and Management Act (Magnuson-Stevens Act). The federal nexus for this project is federal permitting under Section 404 of the Clean Water Act for discharge of fill materials in a jurisdictional water of the U.S. The lead review agency is the U.S. Army Corps of Engineers (Corps). These materials are to be included along with the other JARPA form permit application materials submitted to the Corps. Project Description and Location The City of Renton proposes to improve and upgrade system components and access for the Thunder Hills Sanitary Sewer Interceptor line located adjacent to Thunder Hills Creek. Thunder Hills Sanitary Sewer Interceptor was installed in 1965 and, like many sewer projects of that time, was installed in a ravine to take advantage of favorable gravity-flow conditions. It consists of approximately 3,600 lineal feet of 10-inch to 18-inch concrete pipe that runs beneath or adjacent to Thunder Hills Creek. The depth of the pipe varies, and may be greater than 30 feet in some areas. Currently, access to the existing sewer interceptor is poor and the condition and exact location of the line is unknown. Erosion along the creek has compromised the sewer interceptor in the past; portions of the stream bank were stabilized with gabion baskets in the Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 2 early 1980’s, and more repairs that used large quantities of rip-rap armoring were done in 2008 and 2009. The proposed project is located in the Thunder Hills Creek corridor in Renton, Washington. The project area falls within the Black River (Springbrook Creek) sub-basin of the Duwamish-Green Watershed (Section 20, Township 23 North, Range 05 East; WRIA 9). The portion of the Thunder Hills Sanitary Sewer Interceptor that is being improved runs from Grant Avenue South at its upstream end to I-405. (Figure 1) . Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 3 Figure 1. Depiction of approximate project area and vicinity in Renton, WA. Actual Sewer Interceptor Rehabilitation includes no in-water work, however mitigation and habitat enhancement work associated with the project includes the placement of 9 log, rootwad, and treetop sections along the lower section of creek, extending approximately 250 feet upstream from the I-405 culvert inlet. Construction associated with proposed Sewer Interceptor Rehabilitation, and mitigation for it, will result in some disturbance to streams, wetlands, and their associated buffers, but will also result in net habitat benefits following project implementation. Temporary disturbances will be mitigated in-place, and permanent wetland impacts will be mitigated by purchasing credits in Renton’s Springbrook Creek mitigation bank as well as by log structure placement in and along the stream. Draft construction and mitigation plans for the current project are attached to this letter report. Fish presence has not been documented and is not expected in Thunder Hills Creek during construction within the project area. However, prior to commencement of log structure placement or other activities associated with stream channel and bank enhancements, affected segments will be dewatered and any fish which may be present will be removed through a combination of netting and electrofishing. Proposed channel and bank enhancements include log structure placement and native revegetation. All in-water work activities will occur during the approved general fish window as determined by the Corps and/or the Washington Department of Fish and Wildlife (WDFW) for construction activities in King County streams. Construction involving in-water work (excluding revegetation) is estimated to take approximately six weeks to complete. The standard Corps in-water work window for King County streams is July 1 to September 30. A Hydraulic Project Approval (HPA) from WDFW will include a similar timing restriction. The City of Renton plans to comply with both the Corps and WDFW work windows by completing in-water work between July 1 and September 30, or as allowed or further restricted by permitting conditions including City of Renton permits. Table 1. Applicable work window. Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Federal & State fish protection No In-Water Work In-water work No In-Water Work The following BMPs will be implemented to minimize potential project impacts: 1. Conduct all in-water work during the approved Corps and WDFW general work windows for King County streams. Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 4 2. Though no fish are expected, test the in-water work area for log structure placement for fish use by electrofishing. If fish are found, set up fish screens or block netting upstream and downstream of the project area to identify limits of fish removal. Use seine and dip nets and/or electrofishing equipment in that order of preference to remove any fish from the project area. 3. Place coffer dams and provide a temporary bypass to route water around the project limits. 4. Place erosion control features and elements as shown on the plans to prevent sediment from moving out of the project area. Erosion control will be provided in accordance with both the City of Renton maintenance standard operation procedures and King County Regional Road Maintenance ESA Program Guidelines. 5. After in-water work has been completed, remove the temporary stream bypass by removing first the downstream then the upstream coffer dams and associated bypass piping. 6. Restore all disturbed areas by removing invasive species within the project limits and replanting with woody material including trees, shrubs, and live stakes according to the mitigation planting plans to provide shade and habitat. Action Area The action area includes all areas that may be directly or indirectly affected by the proposed action. Soil and sediment will be disturbed in the process of gaining site access for equipment and materials and during in-stream work to place log structures. Since soils and sediment disturbed by implementation of the project could potentially be transported for a short distance downstream, the disturbance effects of this project on aquatic species could be realized within the existing Thunder Hills Creek channel in the project vicinity. As such, the action area is defined to include the stream channel section within and downstream of the project area up to near the confluence with Rolling Hills Creek, approximately 0.3 mile below the project area (Figure 2). No other in-water areas would be directly or indirectly affected. The outermost extent of the action area for terrestrial species has been determined based on the extent of noise disturbance expected. Maximum terrestrial noise generated from equipment operation is expected to be approximately 87 dB measured 50 feet from the project area (WSDOT 2011). The 87 dB measurement was determined using a decibel escalator calculation based on the three loudest pieces of heavy equipment expected to be used during construction, including an excavator (81 dB), a pump (also 81 dB), and a compactor (83 dB). Based on the logarithmic increase of decibel addition for this equipment, the combined output is anticipated to reach up to 87 dB should these three pieces of equipment be in use simultaneously. The existing background noise level for the terrestrial area is anticipated to be approximately 65 dB, given the urban and industrial conditions surrounding the site. Using these assumptions, Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 5 airborne noise would attenuate to background levels approximately 630 feet (approximately 0.15 mile) from the project site. Note that airborne noise levels above 92 dB, which are considered high enough to injure nesting marbled murrelets, are not expected to occur. Figure 2: Approximate Location of Project and Action Areas Listed Species Federally-listed species for which impacts are to be evaluated for projects occurring within King County were identified from the current species lists on the Services’ websites (USFWS, 2013). The USFWS and NMFS species lists were accessed on their websites on July 28, 2017. Puget Sound Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) are listed on the National Marine Fisheries Service (NMFS) website, and a county-wide species list from the USFWS includes bull trout (Salvelinus confluentus), Canada lynx (Lynx canadensis), gray wolf (Canis lupus), grizzly bear (Ursus arctos horribilis), marbled murrelet (Brachyramphus marmoratus), northern spotted owl (Strix occidentalis caurina), Oregon spotted frog (Rana pretiosa), yellow-billed cuckoo (Coccyzus americanus), streaked horned lark (Eremophila alpestris strigata), and golden paintbrush (Castilleja levisecta).

In addition, an Official Species List of threatened and endangered species that may occur in the project and action areas for proposed Thunder Hills Sewer Interceptor Rehabilitation was compiled and downloaded from the USFWS’ Information Planning and Conservation (IPaC) website on July 28, 2017. Of the King County species listed in Table 2, only bull trout, marbled murrelet, yellow-billed cuckoo, streaked horned lark, and the North American wolverine were identified as potentially being present within the specific project area (though Chinook and steelhead would not be included since they are administered by NMFS). Existing and Baseline Conditions Site visits were conducted to assess current site conditions by Fisheries Biologist Greg Johnston on January 24, 2017 and again accompanied by Water Resource Engineers Ed McCarthy and Logan McClish on May 30, 2017, all of The Watershed Company. The project area is located along approximately 3,600 lineal feet of Thunder Hills Creek in Renton, WA, in the Black River sub-basin of the Duwamish-Green Watershed (WRIA 9). The Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 8 project area is largely forested through a ravine, however power line corridors transect the area in four locations. Vegetation in these corridors consists of disturbed grass, weeds, and shrubs, typically invasive species, with extensive thickets of dense Himalayan blackberry covering large areas. There is an access route along most of the length of the creek within the project area which was originally established as a maintenance access road for the sewer line but which now also serves as a trail. Portions of this route are no longer passable by vehicles, although other sections have been maintained or repaired. Land uses surrounding the wooded Thunder Hills Creek ravine consist primarily of multifamily residential housing. Thunder Hills Creek is a perennial stream that flows north-northwest through the project area. Bed and bank armoring have been placed along significant portions of the stream channel in an effort to prevent erosion. Large, loose riprap occurs throughout the channel, and gabion baskets armor sections in the northern (downstream) portion of the project area. Several small tributary streams and seepages join Thunder Hills Creek along the way. According to City of Renton Maps, SalmonScape, and PHS online mapping and data sources, this section of Thunder Hills Creek is not used by salmonid fish species. A total fish passage barrier is located at the downstream end of the project area due to an impassable culvert under Interstate 405. Additional barriers occur within the project area, most notably a series of high man-made falls and cascades resulting from large amounts of rock placed along the ravine bottom approximately 500-600 feet upstream or Interstate 405. Thunder Hills Creek enters the project area at the upstream end, from the south, via a 36-inch culvert in the vicinity of the intersection of Grant Ave. S. and S 18th Street. Extending upstream, it is piped along S 18th Street and above that flows in a steep-sided ravine for approximately 850 feet below Rolling Hills Avenue SE. Downstream of the project area, Thunder Hills Creek flows beneath interstate 405 and then turns southwest to join Rolling Hills Creek which in turn continues flowing generally towards the southwest in alternating piped and open-channel sections along the way to join Springbrook Creek (See Figure 2). Springbrook Creek joins the remnant Black River channel approaching the Black River pump station, where flows must be pumped in order to keep high tides and flooding from the Duwamish River out of Renton and parts of Kent and Tukwila. The pump station lifts all drainage from the Springbrook Creek basin, including Thunder Hills Creek, into the old Black River channel which then flows into the Duwamish River. http://www.kingcounty.gov/depts/dnrp/wlr/sections-programs/river-floodplain-section/capital- projects/black-river-pump-station.aspx Though the pump station does include fish passage facilities, relatively few salmonid fish, including listed species, are believed to pass upstream of the station each year (WRIA 9 Habitat- limiting Factors and Reconnaissance Report–Part II, https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=8&ved=0ahUKEwiWtvC5 qbTVAhWhh1QKHTqbAdUQFgg- Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 9 MAc&url=http%3A%2F%2Fyour.kingcounty.gov%2Fdnrp%2Flibrary%2F2000%2Fkcr728%2Fvo l2%2FpartIIcontinued%2Fno3%2FSpringbrook%2520Creek.pdf&usg=AFQjCNHZP8nmBTeIc7II R3keSO2ANdl5Dg ).

Species Information, Site Use, and Impacts Fish WDFW Priority Habitats and Species (PHS) maps and data provide details about potential sensitive species in specific project areas. No listed fish species were mapped or listed as occurring in the project or action areas by PHS data. The possible presence of listed fish species in the project area was further investigated by reviewing WDFW Stock Inventory Data and WDFW’s SalmonScape website. No listed fish species were shown to occur in the project or action areas by these sources. Thunder Hills Creek within the action area does not include suitable habitat for listed Chinook salmon, steelhead trout, or bull trout. This lack of suitable habitat for these species is due to its small size and headwater location, the existence of migration barriers and obstacles within and downstream of the project area (including several extensive piped stream sections), and its location upstream of the Black River Pump Station where fish passage facilities are present but are of questionable effectiveness. Based on a lack of documented use and suitable habitat, Chinook salmon, steelhead trout, and bull trout are not expected to be present anywhere within the action area at any time. Therefore, the proposed project will have no effect on Chinook salmon, steelhead, or bull trout. Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 14 Mammals Terrestrial species listed by the USFWS for King County generally do not occur in the project area or vicinity due to the urban nature of the area, and the presence of these species is not indicated by PHS data. The Canada lynx, gray wolf, grizzly bear, and wolverine are wide- ranging species that are found in critically small numbers in Washington with most observations from the northeast corner of the state and portions of North Cascades. The presence of these species in King County is historical, and none are expected to be found in the urban and commercial/industrial landscape associated with the action area. There is no suitable habitat for Canada lynx, grey wolves, grizzly bears, or wolverine in the action area. Therefore, the project will have no effect on Canada lynx, grey wolves, grizzly bears, or wolverine. Birds According to IPaC and USFWS listings for King County, bird species that should be addressed in the action area and its vicinity include the yellow-billed cuckoo, streaked horn lark, northern spotted owl, and marbled murrelet. Yellow-billed cuckoos are extremely rare in Washington, with fewer than 10 recordings since 1950, and the species no longer breeds in Washington, with cessation believed to have occurred by 1934 (WDFW, 2013, pp. 200-202). Yellow-billed cuckoos typically inhabit large, continuous riparian zones dominated by mature cottonwood and willow forests. This habitat community is not present in the action area or the surrounding vicinity. Since there is no suitable habitat, yellow-billed cuckoos are not expected to be present in the action area. Therefore, the project will have no effect on yellow-billed cuckoos. Streaked horned larks typically inhabit sparsely vegetated herbaceous and grassy areas, such as native prairies, coastal dunes, fallow agricultural fields, and grazing lands. The species is known to utilize human-altered landscapes with sparse vegetation, such as the aforementioned agricultural and grazing lands. However, they are highly susceptible to disturbance and are not associated with the commercial, dense residential, and light-industrial landscapes present in the action area and project vicinity. King County is not included on the list of six Washington counties in which the streaked horned lark is known or believed to occur. With no suitable habitat present, streaked horn larks are not expected to be found in the action area. Therefore, the project will have no effect on streaked horned lark. Northern spotted owls require structurally diverse, old-growth and mature coniferous forests. This environment is not present within the action area. Northern spotted owls generally require 2,000 – 5,000 acres of undisturbed contiguous forest, which is not present in the action area. Forested areas within the action area are typically small, highly-fragmented, mixed deciduous forests lacking mature coniferous trees and large snags with cavities suitable for nesting. Based on a lack of suitable habitat, northern spotted owls are not expected to be found in the action area. Therefore, the project will have no effect on northern spotted owls. Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 15 Marbled murrelets forage in nearshore areas in Puget Sound and nest in mature coniferous forests in dense coastal stands. Neither of these habitats is present in the action area. Due to a lack of suitable habitat, marbled murrelets are not expected to be found in the action area. Therefore, the project will have no effect on marbled murrelets. Amphibians There are no federally-listed amphibian species documented in or near the action area. Per IPaC, no listed amphibian species are identified in the action area. In Washington, Oregon spotted frogs are known to occur only within six subbasins/watersheds: the Sumas River; Black Slough in the lower South Fork Nooksack River; the Samish River; Black River, a tributary to the Chehalis River, Outlet Creek, a tributary to the Middle Klickitat River; and Trout Lake Creek, a tributary of the White Salmon River (U.S. Federal Register, 29 August, 2014). The Green/Duwamish watershed, encompassing the Black River/Springbrook Creek subbasins, including tributaries Thunder Hills and Rolling Hills Creeks, is not included in the extant distribution for this species as provided in the referenced USFWS listing documents. However, the Oregon spotted frog inhabits large wetland systems, and the species is identified as potentially occurring in King County, per USFWS. This species is addressed here for thoroughness. The Oregon Spotted Frog Screening Model (WDFW 2004) lists five “Tier 1” criteria, which must all be satisfied for a site to be considered potential habitat for Oregon spotted frogs. An additional Tier 2 criterion must also be satisfied if all five Tier 1 criteria are satisfied. Wetlands that may occur along Thunder Hills Creek in the action area do not meet all the criteria necessary as identified by the model to support the presence of Oregon spotted frogs. Specifically, these wetlands do not meet the criteria for National Land Cover Definition (NLCD) landscape composition, which requires less than 9.8% development within a mile of the wetland’s perimeter. On that basis alone, any wetlands within the action area would not be considered potentially suitable as Oregon spotted frog habitat. Additionally, none of the wetlands in the project action area or vicinity meet the wetland size criterion (>8.9 acres). Critical habitat has recently been designated for the Oregon spotted frog, but does not include any portion of the Duwamish River watershed (WRIA 9), including the project action area along Thunder Hills Creek. Based on a lack of documented presence and the failure to satisfy the required criteria for suitable Oregon spotted frog habitat, Oregon spotted frogs are not expected to be present in the action area. Therefore, the project will have no effect on Oregon spotted frogs. Plants According to IPaC, plant species that should be addressed in the action area include only golden paintbrush. Golden paintbrush is only historically known to occur in King County naturally, with the only current known presence located in the University of Washington Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 16 Botanic Gardens. Golden paintbrush inhabits prairies and flat grasslands situated atop glacially-derived soils, such as glacial outwash prairies. Known golden paintbrush populations in Washington are limited to Thurston, Island, and San Juan Counties. There are no prairie habitats suitable for golden paintbrush in or near the action area. Therefore, the project will have no effect on golden paintbrush. In summary and conclusion, none of the King County Listed Species as included on the King County species lists and in Table 2, above, would be present in the action area for the proposed sewer interceptor line rehabilitation project, and so would not be affected by it. Furthermore, as discussed above, suitable habitat for these species is not present within the proposed project’s action area. Designated Critical Habitat The project and action areas do not include any designated or proposed critical habitat for any ESA-listed species. Essential Fish Habitat Essential fish habitat (EFH) is defined as, “those waters and substrate necessary to fish for spawning, breeding, feeding or growth to maturity.” The Pacific Fisheries Management Council (PFMC) has designated EFH for the Pacific salmon fishery, federally managed ground fishes, and coastal pelagic fisheries. The action area does not include any marine areas. Therefore, ground fish and coastal pelagics are not present in the action area. The Pacific salmon management unit includes Chinook, coho, and pink salmon. None of these species use any of the stream segments in the action area. Chinook salmon have been addressed above. Pink salmon are not indicated by SalmonScape or PHS data as being present in the action area, and they are subject to migration barriers downstream of the action area. They do not use very small streams such as Thunder Hills Creek which do not begin to flow with any appreciable volume in the fall until November or later, since pink salmon spawn in September and October. Therefore, pink salmon are not present in the action area. Neither are Coho salmon documented in the action area, and they are also subject to the migration barriers downstream of the action area. The nearest documented coho presence is in Springbrook Creek, approximately 1.5 miles downstream of the project area and well outside the action area. As described above, suitable habitat for ground fish, coastal pelagics, Chinook salmon, or pink salmon is not present in the project area. Coho salmon could potentially make some use of the project area if several existing migration barriers downstream of the project area were to be removed. Project mitigation including wood placement within the stream channel, removal of non-native vegetation, and native revegetation will improve habitat for coho salmon for their use if access is restored. The project will result in only minor, temporary impacts on water quality. No permanent adverse effects will result from proposed sewer interceptor line Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 17 rehabilitation, which includes some in-stream wood placement, invasive plant removal, and native revegetation as mitigation. Therefore, the project will not adversely affect EFH for ground fishes, coastal pelagics, or Pacific salmonids. Summary of Effects Effects determinations as concluded in the text above are summarized in Table 3, below: Table 3: Effect Determinations Species Species Effect Critical Habitat EFH Chinook salmon No effect No effect Will not adversely affect Steelhead No effect No effect N/A Bull trout No effect No effect N/A Canada lynx No effect N/A N/A Grey wolf No effect N/A N/A Grizzly bear No effect N/A N/A Marbled murrelet No effect No effect N/A Northern spotted owl No effect No effect N/A Yellow-billed cuckoo No effect No effect* N/A Oregon spotted frog No effect No effect N/A Streaked horned lark No effect No effect N/A Golden paintbrush No effect N/A N/A North American Wolverine No effect** N/A N/A Pacific salmon fishery (including pink and coho salmon) N/A N/A Will not adversely affect Federally-managed ground fishes N/A N/A Will not adversely affect Thunder Hills Sewer Interceptor Rehabilitation, No Effect Letter Report Rebecca Saur, Stantec October 20, 2017, Page 18 Coastal pelagic fisheries N/A N/A Will not adversely affect *If critical habitat is designated prior to the completion of this project. **If listed prior to the completion of this project.
