PROJECT DESCRIPTION A. Project Location: Y. Section NW32, Township 24N, Range 05E. 4057 and 4063 Williams Avenue N. Renton, WA 98056 e Latitude: 4 7 .529°N/Longitude: 122.205°W See Figure I for project location. • B. Project Description: The proposed project is a joint-use pier to be located along the common property line between two abutting lots, 4057 and 4063 Williams Ave N, Renton, WA 98056, presently owned by Paul Joos and Conner Homes at Barbee Mill LLC, respectively. The properties are located within the Barbee Mill community, a major waterfront subdivision currently under development by Conner Homes at Barbee Mill LLC along the eastern shore of Lake Washington. The two lots are referred to jointly as the "subject property"; the property owners are jointly the "applicant" for the requested shoreline substantial development permit. The proposed joint-use pier would provide moorage and facilitate access to Lake Washington for residents of the subject property and their guests. The Barbee Mill community dock is a day use only structure and does not provide adequate full-time moorage for the waterfront lot owners. In addition to a landing and moorage facility for watercraft, the proposed joint-use pier would be suitable for launching canoes and kayaks, sun-bathing, swimming, fishing, water skiing and any number of other water sports and activities. · The Barbee Mill community is located on the approximately 22 acre site of the former Barbee Mill Company lumber mill. Lots 23 through 48 are lakefront lots; the subject property is situated on lots 41 and 42. Upon completion, the Barbee Mill community will have 114 multi-story paired homes, a pond, walking trails and lakefront open space for the use of residents. Waterfront open space and trails are also located along May Creek, which flows through the Barbee Mill community. From the proposed joint use pier project site on Lake Washington to the closest point along the May Creek mean high water line is a distance of270 feet. The southeast corner of the subject property is within 200 feet of May Creek, being 120 feet from the May Creek ordinary high water mark at the closest point. A street and the May Creek open space (a riparian buffer) cover the area between the subject property and the May Creek boundary. C. Habitat Data: As a former industrial site, the general development area, including the subject property, was subject to decades of disturbance and degradation by human activity. The Lake Washington shoreline was heavily bulkheaded, back- filled and covered with impervious asphalt paving. Numerous piling and substantial quantities of concrete rubble and other shoreline debris were on site. To restore this former industrial site to a parcel suitable for a residential waterfront subdivision, upland and in-water structures including the mill buildings, timber bulkhead and piling were removed, shoreline rubble was removed, fill soil was excavated to subgrade elevations, and toe rock and a MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 3 • temporary quarry spall erosion control berm were installed. In addition, extensive shoreline restoration was completed which included using sand, gravel and rock materials to construct a beach to mimic natural conditions and installing coir rolls along the Lake Washington ordinary high water line. No additional excavation, grading, clearing or fill material will be required for the proposed pier project. A rock bulkhead about 5' high extending along the subject property shoreline was not impacted by the restoration project, rather it was retained, is currently intact, and protects the approximately 67' of subject property shoreline. The substrate immediately waterward of the bulkhead consists oflarge and small cobble. The subject property is located south of, and was not included in, the area requiring the most extensive remediation. The study area includes no wetland or flood hazard areas but it does include Lake Washington riparian areas. Prior to the site restoration, riparian vegetation was found to be generally absent in the Barbee Mill community development area due to extensive paving. In unpaved areas, vegetation noted included Juncus ejfusus (soft rush) and Iris pseudocaris (a non-native iris). In accordance with the general development mitigation planting plan, native plants were installed along the entire Barbee Mill community Lake Washington shoreline, including the subject property shoreline. In conjunction with construction of the proposed joint-use pier, additional native plants, shrubs and/or trees will be planted as specified in applications to, and as approved by, the Washington State Department of e Fish and Wildlife and the U. S. Army Corps of Engineers. Until the extensive site restoration was completed, the industrial use of the property limited the ecological functions that would otherwise have been provided by Lake Washington and its adjacent riparian area. As a result of the extensive remediation, beach reconstruction and plantings, the ecological functions of the Lake Washington shoreline within the study area should be greatly enhanced. The addition of riparian vegetation to this formerly near-barren site should help water quality by filtering pollutants, removing nutrients and reducing sediments in any runoff from the adjacent upland development while helping to stabilize and protect the shoreline from erosion. The riparian vegetation planted and to be planted should increase the habitat available for aquatic invertebrates and fish; the addition of organic matter to the lake substrate from fallen and washed in leaves and woody debris will provide them with food, shelter and shade. Increased overhanging vegetation will also provide shade and predator protection for fish and aquatic invertebrates and may facilitate the migration of juvenile salmon. Terrestrial insects will benefit from the food and shelter provided by newly planted vegetation, which in turn will provide an additional food source for the birds and animals that feed upon them. The Washington State Department of Fish and Wildlife Priority Habitat and Species database (http://wdfw.wa.gov/hab/phslist.htrn) identifies habitats and species considered to be priorities for conservation and management. Listed species observed in the general Barbee Mill community development area include bull trout, Puget Sound chinook salmon, Puget Sound steelhead, and marbled murrelet, all of which are discussed below. Protected wildlife in Washington State shall not be hunted or fished (WAC 232-12-011). Protected wildlife noted from time to time within the general Barbee Mill community development area include the marbled murrelet and the bald eagle. The marbled murrelet is classified as a "threatened species," a species likely to become endangered e within the foreseeable future throughout a significant portion of their range within the state without cooperative management or removal of threats. The bald eagle is no longer on the list of threatened or endangered species under the Endangered Species Act (ESA) but continues to be protected by the Bald and Golden Eagles Protection Act and the Migratory Bird Treaty Act and is protected as a "sensitive species" in Washington. Sensitive species are vulnerable or declining and likely to become endangered or threatened in a significant portion of their range within the state without cooperative management or removal of threats. The only eagle nests observed near the subject property are two nests approximately 0.65 mile from the site on the opposite shore. • D. Construction Sequence: The proposed project will consist of a fully grated 370 ft' joint-use pier with a 3'-9" x 36' fully grated ramp and a 5'- 10\6'' x 40' fully grated pier and four 10" mooring piles. The pier will be supported by six 8" diameter steel batter piles (Figure 3) to be constructed in the following sequence: MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 4 • • • .. 1. Mobilize construction barge to the site with all construction materials and equipment on board. Moor the barge as to prevent grounding on the lake bottom at any time. 2. Install silt containment curtain around work area to contain any debris that may fall into lake waters. In the event any materials enter lake waters they will be retrieved immediately and placed in debris containers on the barge. 3. Using the barge-based crane and vibratory insertion/extraction system, install six 8" diameter steel batter piles to practical refusal. If required, proof piles using a drop hammer pile driver with a 6" minimum block of wood between pile driver and pile. 4. Cut steel piling as necessary at the appropriate elevation. 5. Install pre-fabricated pier onto pipe collar assembly and secure to piling. 6. Install the pre-fabricated ramp into place and secure to the pier and shore mount. 7. Using the barge-based crane and vibratory insertion/extraction system, install four IO" diameter steel mooring piles to practical refusal. If required, proof piles using a drop hammer pile driver with a 6" minimum block of wood between pile driver and pile. 8. Cut steel mooring piling as necessary to appropriate elevation and install cones. 9. Demobilize and dispose of all debris at approved upland disposal site. ATTENTION: Fisheries alert! If at any time, as a result of project activities, fish are observed in distress, a fish kill occurs, or water quality problems develop (including equipment leaks or spills), operations shall cease and the WDFW at (360) 534-8233 and Washington Department of Ecology at (425) 649-7000 shall be contacted immediately. Work shall not resume until further approval is given by the WDFW. D. Action Area: The action area should include the area within a one-mile radius of the project location. This area includes potential turbidity and noise impacts from the construction process. II. SPECIES AND HABITAT INFORMATION A. Species Information: In the project area, the Puget Sound chinook ( Oncorhynchus tshawytscha) is listed under the Endangered Species Act as a threatened species according to the National Marine Fisheries Service (NMFS)(Federal Register, Vol. 64, No. 56). On May 11, 2007, NMFS also listed the Puget Sound steelhead (Oncorhynchus mykiss) as a threatened species under the ESA (Federal Register/ Vol. 72, No. 91 / Friday, May 11, 2007 / Rules and Regulations). Bull trout (Salvelinus confluentus) were listed as threatened by the United States Fish and Wildlife Service (USFWS) in October of 1999. On September 2, 2005, NMFS issued the final rule designating critical habitat for 12 Evolutionarily Significant Units (ESUs) of West Coast salmon, including the Puget Sound Chinook Salmon ESU and the Hood Canal Summercrun Chum ESU. The project site is in an area designated as critical habitat for the Puget Sound Chinook ESU (Federal Register/ Vol 70, No.170 / Friday, September 2, 2005 Rules and Regulations). USFWS has designated critical habitat in Lake Washington for Coastal-Puget Sound bull trout (Federal Register/ Vol. 70, No. MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 5 • • • • 185 / September 26, 2005 / Rules and Regulations). Puget Sound Chinook: Puget Sound chinook, also called the king salmon, are distinguished from all other Pacific salmon by their large size. Most chinook in the Puget Sound are "ocean-type" and migrate to the marine environment during their first year (Myers et al. 1998). They may enter estuaries immediately after emergence as fry from March to May at a length of 40 mm., or they may enter the estuaries as fingerling smelts during May and June of their first year at a length of 60-80 mm. (Healey 1982). Chinook fry in Washington estuaries feed on emergent insects and epibenthic crustaceans (gammarid amphipods, mysids, and cumaceans). As they grow and move into neritic habitats, they feed on decapod larvae, larval and juvenile fish, drift insects, and euphausiids (Simenstad et al. 1982). These ocean-type chinook use estuaries as rearing areas and are the most dependent of all salmon species on estuaries for survival. Adult chinook migrate through Lake Washington to reach spawning grounds in the Cedar and Sammamish Rivers and Issaquah Creek. Juvenile salmonids leaving the Cedar River are found primarily in the south end of Lake Washington from January to May, mostly in the littoral zone (Tabor et al. 2004) . Bull Trout: Coastal-Puget Sound bull trout have ranged geographically from northern California (at present they are extinct in California) to the Bering Sea coast of Alaska, and northwest along the Pacific Rim to northern Japan and Korea. Bull trout are members of the char subgroup of the salmon family. Spawning occurs typically from August to November in streams and migration to the open sea (for anadromous populations) takes place in the spring. Eggs and juveniles require extremely cold water for survival. Temperatures in excess of about 15 degrees Care thought to limit bull trout distribution (Rieman and McIntyre 1993). They live both in fresh and marine waters. Some migrate to larger rivers (fluvial), lakes (adfluvial), or saltwater (anadromous) before returning to smaller streams to spawn. Others (resident bull trout) complete all of their life in the streams where they were reared. Habitat degradation, dams and diversions, and predation by non-native fish threaten the Coastal-Puget Sound population. The Coastal-Puget Sound bull trout population is thought to contain the only anadromous forms of bull trout in the contiguous United States (Federal Register, Vol. 64, No. 210, 1999). Two subpopulations of bull trout (also known as "native char") are considered within the Lake Washington area: the Chester Morse Reservoir population and the Issaquah Creek-Sammamish River population (Federal Register, Vol. 64, No. 210, 1999). "Only two 'native char' have been observed during the past 10 years in the Issaquah Creek drainage and none have been observed in the Sammamish River system, which area occupied by the Sammamish River-Issaquah Creek subpopulation. It is questionable whether a viable subpopulation remains." (Federal Register, Vol. 64, No. 210, 1999). Puget Sound steelhead: Wild winter steelhead enter the Lake Washington system in mid-December with peak spawning taking place in May. There have been high rates of predation by California sea lions at the Ballard Locks, which is one of the leading factors in the declining steelhead production in the Lake Washington system (1992 Washington State Salmon and Steelhead Stock Inventory. Appendix One -Puget Sound Stocks. Washington Department of Fish and Wildlife, Olympia, WA.). According to Sam Wright, a retired state fishery manager, "In the Lake Washington system, they're functionally extinct." (Quoted in an article by Robert McClure in the Seattle Post-Intelligencer, March 30, 2006). McClure states, "Fifty or fewer adult steelhead have returned to the Lake Washington/Cedar River ecosystem in the past four years." Marbled Murrelets: Marbled murrelets are small marine birds in the alcidae family. They spend most of their time at sea and only use old growth areas for nesting. In the critical nesting areas, fragmentation and loss of old growth forest has a significant impact on the survival and conservation of the species (WOW, 1993). Adult birds are found within or adjacent to the marine environment where they dive for sand lance, sea perch, Pacific herring, surf smelt and other small schooling fish, and feed on invertebrates. Annual aerial surveys for marbled murrelets (Marine Bird and Mammal Component of the Puget Sound Ambient Monitoring Program, WDFW) indicate that no marbled murrelets make use of nearshore habitat in the project area. There are no documented MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 6 • • • • nests or old growth nesting habitat near the project site, (Nordstrom, pers. comm.). Ill. EFFECTS OF THE ACTION The status of each of the listed species in the action area has been provided. The proposed project has been described and the action area defined. When reviewing all the data, the potential direct and indirect effects of the proposed action on the listed species and their critical habitat should be considered. A. Direct Effects: When considering the direct effects of the proposed project, one must determine if the proposed project will immediately reduce or destroy the listed species and/or their habitat. The potential, direct impacts caused by the construction process include increased noise and turbidity. Pile driving noise: A vibratory pile driver will be used in the proposed project. If required, piles will be "proofed" using a drop hammer pile driver with a 6" minimum block of wood between pile driver and pile. Feist et al. ( 1992) reported that salmonids could be expected to hear pile driving noise approximately 2,000' from the source. Based on the studies at the Everett Homeport, these researchers concluded that pile driving did alter the distribution and behavior of juvenile pink and chum salmon. However, the Everett Homeport results may not be entirely applicable to the proposed project, because a diesel powered compression hammer was used in that study. As stated in the Feist report, "It would be reasonable to say that juvenile salmonids might respond differently to the sounds of a vibratory hammer, compared to that of a diesel compression hammer." As noted above, annual aerial surveys for marbled murrelets indicate that no murrelets have been seen near the Lake Washington project area during either the summer or winter. Therefore, the construction process should cause no impacts on marbled murrelets. Turbidity: Increased turbidity caused by pile driving, pile removal and bulkhead replacement could, under certain circumstances, have adverse effects on salmon and bull trout. The effects depend on duration of exposure, concentration of turbidity and the life stage of the salmon during the increased exposure. The effects can be discussed in terms of lethal, sublethal or behavioral (Nightingale and Simenstad 2001a and Simenstad, editor, 1988). A silt containment curtain will be installed in the project area to contain and minimize turbidity impacts. To minimize the adverse effects of increased turbidity and noise on migrating salmonids and bull trout, inwater construction work will take place during the approved work window from July 16 to December 31. Overwater work can proceed outside of the inwater work window. B. Indirect Effects: Indirect effects are effects of the project that occur later in time. For this project, indirect effects might include alteration of juvenile salmon migratory pathways, increase in salmonid predation and reduction in prey resources and refugia due to shading of the epibenthic substrate by the structure. Migratory pathway alteration: There were no studies specifically investigating the effects of piers on salmonid migration in lakes cited by Kahler et al. (2000) in their review of pier-related impacts in lakes. Concerning the lake environment, Kahler et al. (2000) state, "The question remains whether juvenile salmonids in lakes migrate MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 7 • • • • under, or otherwise utilize, piers, or if they avoid them and/or traverse their perimeter." However, in the marine environment, it is generally accepted that overwater structures can alter migration behavior of juvenile salmon (though the effects may vary depending on the design and orientation of the structure, degree of shading, and the presence of artificial light), and reduce salmon prey resources and refugia by shading aquatic plant life (Simenstad et al. 1999; Nightingale and Simenstad 2001b). However, the significance of these effects is not clear. As Simenstad et al. state, "We found no studies that described empirical evidence supporting or refuting that modification of juvenile salmon behavior in shoreline habitats was reflected in changes in survival." Nightingale and Simenstad (2001b) state, "Presently, although we know that under some conditions small juvenile salmon will delay or otherwise alter their shoreline movements when encountering an overwater structure, the conditions under which this behavioral modification is significant to the fishes' fitness and survival is relatively unknown." A study by Williams et al. (2003) at the Mukilteo ferry terminal, found that, "Salmon fry were observed in all nearshore habitats during each transect sampling period (day and night). The fry were observed under a wide range of PAR values (0.0 µmo! m-2 s-1 to 2370 µmo! m-2 s-1). Fry were observed both outside the terminal and underneath the terminal at all times, and shadows produced by the I 0-m-wide terminal structure did not appear to act as barriers to fry movement at this location." There is no question that underwater structures may alter migration patterns -that is not in dispute. As seen in the study by Williams and in many other studies (see the recent literature review by Weitkamp -2003), there are studies that indicate that salmon migration is not affected by the presence of overwater structures. Of course, there are other studies indicating migration patterns are altered by overwater structures. The issue is that no one has shown that these migration changes lead to increased mortality or decreased fitness. None of the studies that report changes in salmonid migration patterns caused by overwater structures in the marine environment have reported that these changes have a negative impact on salmonids. Increased predation and shading impacts on primary production: Shading caused by overwater structures can reduce aquatic macrophytes and other epibenthic organisms resulting in reduced primary production. An additional concern about the impacts of overwater structures on migrating salmon is that they will be forced to move out into deeper water, where they will be consumed by predatory fish species. However, in a study conducted in the marine environment, Williams et al. (2003) noted:. We found no evidence that avian, marine mammal, or fish predators consumed more juvenile salmon near WSF terminals than along shorelines without overwater structures. Few species appeared to be targeting abundant fry in nearshore habitats, and we observed only two occasions in which predators (one tern sp., one staghorn sculpin) had consumed juvenile salmon. The authors also state, Our analysis of fish diets at the Mukilteo ferry terminal provides one piece of conclusive evidence that juvenile salmon were not a major dietary component of predatory fish species during our study. It should be noted that the Williams study was conducted in the marine, not lake, environment. In Lake Washington, smallmouth bass migration into the littoral zone corresponds with the peak occurrence of migrating salmonids in this zone (Fresh et al. 2001). Because of these similar migration patterns, salmonids are most at risk of predation from smallmouth bass in Lake Washington. Bass prefer complex, natural cover for their foraging environment. When there is a scarcity of natural cover for foraging, as is the situation in Lake Washington, they tend to use the dominant structures in the environment, such as pilings and piers, for foraging cover (Kahler et al. 2000). There is concern that increasing the number of overwater structures will increase the predation success of smallmouth bass on migrating salmonids. Tabor et al. (2004) investigated predation of juvenile chinook salmon in three areas of the Lake Washington MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 8 • • • • Basin. One of the areas they looked at was the south end of Lake Washington, an important rearing area. The investigators found that: The only predators observed to consume Chinook salmon were cutthroat trout, prickly sculpin (C. asper), smallmouth bass (Micropterus do/omiew), and largemouth bass (M salmoides). Consumption of Chinook salmon by cutthroat trout was observed in February, March and early April. Predation by prickly sculpin was only observed in February. Smallmouth bass consumed Chinook salmon in May and June. Few largemouth bass were collected; however, we did document a largemouth bass that had consumed a Chinook salmon in June. We estimated a total of 1,400 Chinook salmon fry were consumed by littoral predators from February to mid May ..... Based on consumption estimates and expected abundance of juvenile Chinook salmon, predatory fishes probably consumed less than 10% of the fry that entered the lake from the Cedar River. The investigators in this study did not comment on the impacts of overwater structures on the predation rate found in south Lake Washington. The following design components will reduce foraging cover and allow more light penetration under the proposed pier. I. The proposed pier and ramp will be fully grated. 2. The bottom of the proposed pier will be 18" above OHWL. 3. The smallest number and diameter steel pilings will be used to minimize the structure in the water and the disturbance caused by pile driving. 4. Glu-lam stringers will be used to allow the longest possible spans between pilings. C. Interrelated/Interdependent Effects: Completion of this project will not promote future construction or other activities that would not otherwise occur without its completion. Therefore, no additional interrelated or interdependent actions that could affect species regulated under ESA will occur because of this project. D. Take Analysis: "Take" is defined as, "to harass, harm, pursue, hunt, shoot, wound, trap, capture, collect or attempt to engage in any such conduct." The USFWS further defines "harm" as "significant habitat modification or degradation that results in death or injury to listed species by significantly impairing behavioral patterns such as breeding, feeding, or sheltering." It is likely that no "take" will result from this project. E. Conservation Measures: In order to minimize any direct effects on the listed species caused by this project, inwater work should take place between July 16 and December 31. Additional impact reduction and mitigation measures will reduce adverse impacts of the project. They include: 1. The proposed joint-use pier and ramp will be fully grated. 2. The bottom of the proposed pier will be 18" above OHWL. 3. The smallest number and diameter steel pilings will be used to minimize the structure in the water and the disturbance caused by pile driving. 4. Glu-lam stringers will be used to allow the longest possible spans between pilings. MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 9 • • • • 5. A silt containment curtain will be installed before construction begins to contain any debris that may fall into the water. 6. A vibratory pile driver will be used. If a drop hammer is required for proofing, sound attenuation measures recommended by NOAA-Fisheries and U. S. Fish and Wildlife will be implemented. 7. Native vegetation has been installed along the shoreline in conjunction with upland development. Additional native riparian vegetation will be installed as part of the project. F. Determination of Effect: After reviewing the appropriate data and surveys, the effect determinations for the impacts of the project, as designed, are: 1. Puget Sound chinook -"May affect, not likely to adversely affect" 2. Bull trout -"May affect, not likely to adversely affect" 3. Puget Sound steelhead -"May affect, not likely to adversely affect" 4. Marbled mu"elet -''No effect" This is the appropriate conclusion when effects on the species and their critical habitat are expected to be beneficial, discountable or insignificant. Limiting constructio11 work to the approved work window will reduce direct impacts on the listed species. Shading impacts on the benthic environment will be minimized by the conservation measures discussed above .

Essential Fish Habitat Assessment A. Background The Magnuson-Stevens Fishery Conservation and Management Act (MSA), as amended by the Sustainable Fisheries Act of 1996 (Public law I 04-267), requires Federal agencies to consult with NMFS on activities that may adversely affect designated Essential Fish Habitat (EFH) for the relevant species. According to the MSA, EFH means "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." For the Pacific West Coast, the Pacific Fisheries Management Council (Council) has designated EFH for federally managed groundfish (PFMC 1998a), coastal pelagic (PFMC 1998b) and Pacific salmon fisheries (PFMC 1999). The purpose of the EFH Assessment is to determine the effects of the proposed project on the EFH for the relevant species and to recommend conservation measures to avoid, minimize or otherwise offset adverse effects on EFH. B. Identification of EFH The designated EFH for groundfish and coastal pelagic species encompasses all waters from the mean high water line, and upriver extent of saltwater intrusion in river mouths, along the coasts of Washington, Oregon and California, seaward to the boundary of the U.S. exclusive economic zone (370.4 km) (PFMC 1998a, 1998b). The designated EFH in estuarine and marine areas for Pacific salmon species extends from the nearshore and tidal submerged environments within state territorial water out to the full extent of the exclusive economic zone (370 .4 km) offshore of Washington, Oregon and California north of Point Conception to the Canadian border PFMC, 1999). Freshwater EFH for Pacific salmon includes all those streams, lakes, ponds, wetlands and other water bodies currently, or historically accessible to salmon in Washington, Oregon, Idaho and California, except areas upstream of certain impassable man-made barriers, and longstanding, naturally-impassable barriers. Chinook salmon and coho salmon are the species with designated EFH that are found in Lake Washington C. Proposed Action The details of the proposed project are presented in Project Description section of the attached BE. D. Effects of the Proposed Action The effects of this project on designated EFH are likely to be similar to the effects described in detail in the Effects Analysis section of the attached BE. The project is likely to have no permanent, long-term effects EFH designated for chinook and coho salmon. E. EFH Conservation Measures The conservation measures and BMP's mentioned in the attached BE will be implemented to minimize possible adverse effects to EFH. MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 24 • • • • F. Conclusion The project may have temporary adverse effects on EFH the salmon species, but will not produce long-term adverse effects on EFH for the above species. The conservation measures and BMP's mentioned in the attached BE will be implemented to minimize any possible the temporary adverse effects on EFH. G.

Assessment of Impacts to Critical Habitat for Puget Sound Chinook Project description: Construction of a new joint-use pier on Lake Washington in Renton, WA The site is located in the Lake Washington watershed, 1711001203. This assessment covers the primary constituent elements (50 CFR Part 226, page 74581-2) determined essential to the conservation of Puget Sound Chinook salmon ( Oncorhynchus tshawytscha): (1) Freshwater spawning sites with water quantity and quality conditions and substrate supporting spawning, incubation, and larval development. Existing Conditions: There are no suitable freshwater spawning sites in the project vicinity e (2) Freshwater rearing sites with water quantity and floodplain connectivity to form and maintain physical habitat conditions and support juvenile growth and mobility; water quality and forage supporting juvenile development; and natural cover such as shade, submerged and overhanging large wood, log jams and beaver dams, aquatic vegetation, large rocks and boulders, side channels, and undercut banks. • • Existing Conditions: Native vegetation has been planted immediately landward of the bulkhead in conjunction with the upland development. There is a rock bulkhead along the shoreline of both properties. No side channels or undercut banks were noted. (3) Freshwater migration corridors free of obstruction with water quantity and quality conditions and natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, side channels, and undercut banks supporting juvenile and adult mobility and survival. Existing Conditions: See (2) above.

MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 26 • • • • Effects Analysis: A complete discussion of the effects of this project is seen in the BE. Construction will produce brief and localized increased turbidity, which will be contained by a silt curtain. The project will have no long-term impacts on water quantity, salinity conditions or water temperature. Construction during work windows will prevent impacts to the listed fish species. Shading impacts on the benthic environment will be reduced by design components of the proposed project. The entire dock will be fully grated Determination of Effect: "May affect, not likely to adversely affect" MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 27 • Attachment 5. Assessment of Impacts to Crilicol Habitat for Coastal -Puget Sound Bull Trout COE reference: Unknown at this time Applicant: Conner Homes at Barbee Mill LLC/Paul Joos The primary constituent elements determined essential to the conservation of bull trout (Salvelinus conjluentus) are: (1) Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures from 32 to 72 °F (0 to 22 °C) but are found more frequently in temperatures ranging from 36 to 59 °F (2 to 15 °C). These temperature ranges may vary depending on bull trout life history stage and form, geography, elevation, diurnal and seasonal variation, shade, such as that provided by riparian habitat, and local groundwater influence. e Stream reaches that preclude bull trout use are specifically excluded from designation. Existing Conditions: The project will take place in Lake Washington, a large body of fresh water. Effects to PCE: The project is not expected to have any influence on the water temperature of Lake Washington. (2) Complex stream channels with features such as woody debris, side channels, pools, and undercut banks to provide a variety of depths, velocities, and in stream structures. Existing Conditions: Project will take place in Lake Washington -not in a stream environment Effects to PCE: No effect (3) Substrates of sufficient amount, size and composition to ensure success of egg and embryo overwinter survival, fry emergence, and young-of-the year and juvenile survival. This should include a minimal amount of fine substrate less than 0.25 in (0.63 cm) in diameter. Existing Conditions: No spawning activity at the site Effects to PCE: No effect • (4) A natural hydrograph, including peak, high, low, and base flows within historic ranges or, ifregulated, currently operate under a biological opinion that addresses bull trout, or a hydrograph that demonstrates the ability to support bull trout populations by minimizing daily and day-to-day fluctuations and minimizing departures from the natural cycle of flow levels corresponding with seasonal variation: This rule finds that reservoirs currently operating under a biological opinion that addresses bull trout provides management for PCEs as currently operated. • Existing Conditions: Project will take place in Lake Washington Effects to PCE: The project does not involve any alteration in the lake level; therefore it will have no impact on this PCE. MS&A Conner Homes at Barbee Mill LLC/ Joos Joint-Use Pier Project • 28 • (5) Springs, seeps, groundwater sources, and subsurface water to contribute to water quality and quantity as a cold- water source. Existing Conditions: See 4 above Effects to PCE: This project will have no impact on springs, seeps, groundwater sources or subsurface water (6) Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing, overwintering, and foraging habitats, including intennittent or seasonal barriers induced by high water temperatures or low flows. Existing Conditions: Native vegetation has been planted along the site shoreline. Effects to PCE: The proposed dock will incorporate design components that will decrease negative impacts on foraging habitat and migratory corridors. The proposed dock will be fully grated and supported by the smallest number and diameter steel pilings, which will cause minimal physical, biological or water quality impediments. e (See the BE for details). • • (7) An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish. Existing Conditions: Native vegetation has been planted along the site shoreline. Effects to PCE: See 6 above (8) Pennanent water of sufficient quantity and quality such that nonnal reproduction, growth and survival are not inhibited. Existing Conditions: See 4 above. Effects to PCE: Pile driving may produce temporary turbidity impacts .. These are expected to be short tenn and are not expected to have a significant impact on critical habitat. Any debris associated with the project construction phase will be contained by a silt containment c~in. Determination of Effect: ''No destruction or adverse modification" Conservation Measures: Conservation measures for this project are seen in the Biological Evaluation .

PROJECT LOCATION AND DESCRIPTION Project Purpose and Location: The proposed project is a joint-use pier to be located along the common property line between two abutting lots, 4057 and 4063 Williams Ave N, Renton, WA 98056 (jointly the "subject property"), presently owned by Paul Joos and Conner Homes at Barbee Mill LLC, respectively, (jointly the "applicant" for the requested shoreline substantial development permit). The properties are located within the Barbee Mill Community, a major waterfront subdivision currently under development by Conner Homes at Barbee Mill LLC. The subject property is located along the eastern shore of Lake Washington in the City of Renton in Section 32, Township 24N, Range 5E; Latitude 47.529"N/Longitude 122.205°W. The proposed joint-use pier would provide moorage and facilitate access to Lake Washington for residents of the subject property and their guests. The Barbee Mill Community Dock is a day use only structure and does not provide adequate full-time moorage for waterfront lot owners. Two bodies of water are adjacent to, or flow through, the Barbee Mill Community: Lake Washington and May Creek. The subject property is located along Lake Washington, a Shoreline of Statewide Significance as provided in RMC 4-3-090Fl, and a Shoreline of the State under RMC 4-11-190. This Standard Stream or Lake Study is prepared in accordance with the requirements of RMC 4-8-120D with respect to the Lake Washington shoreline of the subject property and the 100' of abutting lakeshore lots both to the north and to the south of the subject property (the "study area"). May Creek, a Shoreline of the State (RMC 4-3-090F2), flows through the Barbee Mill Community. The southeast comer of the subject property is within 200 feet of May Creek, being 120 feet from the May Creek ordinary high water mark at the closest point. However, the proposed pier project site is on Lake Washington, along the common property line between the two subject property lots, a distance of 270 feet to the closest point along the May Creek mean high water line. The community May Creek open space (a riparian buffer) and a street cover the area between the southeastern comer of the subject property and May Creek. Project Description: The Barbee Mill community is being developed by Conner Homes at Barbee Mill LLC on the approximately 22 acre site of the former Barbee Mill Company lumber mill. Upon completion, the Barbee Mill community will have 114 multi-story paired homes, a pond, walking trails and lakefront open space for the use of residents. Lots 23 through 48 are lakefront lots; the subject property is situated on lots 41 and 42. To restore the former industrial site to a parcel suitable for a residential waterfront subdivision, the mill buildings were demolished; fill soils were removed from behind the bulkhead; asphalt paving, a pier, the wooden bulkhead and piling associated with the mill operation were removed; and extensive shoreline restoration was completed. The subject property is located south of, and was not included in, this extensive remediation. A rock bulkhead about 5' high extending along the subject property shoreline was not impacted by the restoration project, rather it was retained, is currently intact, and protects the approximately 67' of subject property shoreline. The substrate immediately waterward of the bulkhead consists of large and small cobble. Under the proposed project plan, a joint-use pier would be constructed on the common property line (approximate coordinates of 47.529° N, 122.205° W). The pier would be oriented slightly north to keep all structures and moorage within the side property setbacks of each property in compliance with all City of Renton zoning and municipal codes. (Attachment 2) The proposed joint-use pier would provide convenient Lake Washington access and moorage capabilities from each of the subject property lots. Residents and their guests would have use of the pier for swimming, fishing, water skiing and any number of other water sports and activities. Mr. Joos MS&A Conner Homes Company/ Joos Joint Use Pier Project • 3 • • • • and Conner Homes at Barbee Mill LLC considered a nwnber of factors in determining the location of the proposed pier, most importantly the lower environmental impact of a joint-use structure over individual single-property use piers. In establishing design parameters for the proposed joint-use pier, they required that it not interfere with the general public's use and enjoyment of Lake Washington, that it not pose a navigation hazard to boaters, and that it not interfere with the use of existing or future neighboring docks or piers. 2. LAKE AND STREAM CLASSIFICATIONS As a Shoreline of Statewide Significance (RMC 4-3-090Fl), Lake Washington is included in the definition of a Shoreline of the State (RMC 4-11-190). Lake Washington is a Class 1 lake as it is a perennial salmonid-bearing body of water classified as a Shoreline of the State (RMC 4-l l - 190S l ). May Creek is an important salmonid stream that is classified by the City of Renton and the State of Washington as Class 1 waters and included within the definition of a Shoreline of the State (RMC 4-3-090F2). 3. SHORELINE RESTORATION AND OHW MARK Shoreline Restoration: Prior to restoration of the beach in conjunction with vacation of the land, the Lake Washington shoreline north of the subject property was heavily bulkheaded, back-filled and covered with impervious asphalt paving; numerous piling and substantial quantities of concrete rubble and other shoreline debris were on the site. Pursuant to the general development site remediation, upland and in-water structures including the timber bulkhead and piling were removed, shoreline rubble was removed, fill soil was excavated to subgrade elevations, toe rock and a temporary quarry spall erosion control berm were installed, and sand, gravel and rock materials were used to construct a beach to mimic natural conditions. Although the area of extensive remediation did not encompass the subject property, a planting buffer of native vegetation was installed along all the lakefront lots, including the subject property, to environmentally and functionally enhance the entire development shoreline. There would be no clearing or grading associated with the proposed joint-use pier. OHWMark: The Ordinary High Water (OHW) mark for Lake Washington is the line of mean high water (RMC 4-11-150 Definitions 0). The Lake Washington water depth is controlled by the Army Corps of Engineers at the Hiram M. Chittenden Locks and is at 21. 8' of lake elevation. In the course of the Barbee Mill Beach Restoration site remediation, permanent toe rock was installed along the OHW line. As of March 20, 2007, the date the SCUBA survey was conducted for purposes of identifying flora, fauna, substrate types and other qualitative information relative to the Biological Evaluation prepared for the previous community dock project, coir rolls were located along the OHW line within the remediation area. The May Creek OHW mark is the mean high water line of the stream (RMC 4-11-150 Definition 0). 4. VEGETATIVE COVER OF THE SITE The study area includes no wetland or flood hazard areas; it does include Lake Washington riparian areas. Prior to the Barbee Mill Beach Restoration project, riparian vegetation was found to be generally absent within the study area as the shoreline behind the bulkhead was paved. In unpaved areas, vegetation noted included Juncus ejfusus (soft rush) and Iris pseudocaris (a non- native iris). The upland redevelopment required extensive regrading and clearing; a mitigation planting plan was agreed upon that includes planting along the Lake Washington shoreline. In accordance with this mitigation plan, plantings on the subject property have been installed. In conjunction with construction of the proposed joint-use pier, additional native plants, shrubs and/or trees will be planted as specified in applications to, and as approved by, the Washington State Department of Fish and Wildlife and the U.S. Army Corps of Engineers . MS&A Conner Homes Company/Joos Joint Use Pier Project • 4 • • • • The following species are included in the preliminary plant list for the shoreline buffer zone: Trees: Amelanchier alnifolia (Serviceberry) Fraxinus latifolia (Oregon Ash) Pinus contorta (Shore Pine) Salix sitchensis (Sitka Willow) Shrubs: Cornus sericea (Red-osier Dogwood) Cornus sericea 'Flaviramea' (Yellow Twig Dogwood) He/ictotrichon sataecetum (Blue Oat Grass) Mahonia aquifolium (Tall Oregon Grape) Mahonia nenosa (Low Oregon Grape) Ribes sanguineum (Red Flowering Currant) Symphoricarpos a/bus (Snowberry) Groundcovers: Allium cernuum (Nodding Onion) Armeria maritima (Thrift) Arctostaphylos uva-ursi (Kinnikinnik) Fragaria chiloensis (Beach Strawberry) Symphoricarpos mollis (Trailing Snowberry) In the course of the March 20, 2007, SCUBA survey for the community dock project, Myriophyllum spicatum (Eurasion Milfoil), an invasive nonnative plant, was found along all transects. No planting is proposed below the OHW line. 5. ECOLOGICAL FUNCTIONS OF LAKE WASHINGTON ALONG STUDY AREA Until relatively recently, the industrial structures and use of the site limited the ecological functions that would otherwise have been provided by Lake Washington and its adjacent riparian area. As a result of the extensive general site restoration work completed north of the subject property, including removal of the wooden bulkhead, large pier and numerous pilings, excavation of fill soil from behind the bulkhead, and reconstruction of the beach to mimic its natural state, the ecological functions of the portion of the lake within the study area should be greatly enhanced. Recently planted riparian vegetation and additional plantings in conjunction with the proposed joint-use pier project will further assist in restoring the ecological functions of Lake Washington. Much of this new vegetation will be overhanging, providing shade and predator protection for fish and aquatic invertebrates. The newly planted riparian vegetation will add significant organic matter to the lake substrate in the form of leaves and woody debris that fall and wash in; an additional source of food, shelter and shade for aquatic invertebrates and fish. This increased vegetation will also provide food and shelter for terrestrial insects, and in turn provide an additional food source for birds and animals that feed upon them. The addition of riparian vegetation to this formerly near-barren site should also help water quality by filtering pollutants, removing nutrients and reducing sediments in any runoff from the adjacent upland development. The smaller design of the proposed pier as compared to the structures removed, together with increased overhanging vegetation, may facilitate the migration of juvenile salmon. 6. FISH OR WILDLIFE USE OF AREA Birds: Birds observed on or near the site include hawks, herons, eagles, quail, osprey, cormorants and songbirds. Before the mill structures were demolished, an osprey nest was successfully relocated from the top of the old mill sawdust collector to a platform built on a 25' pole over the water not far from the original nest site. The osprey have accepted the new nest and a video camera records MS&A Conner Homes Company/ Joos Joint Use Pier Project • 5 • • • • their activities for viewing over the Internet. Although the bald eagle is no longer on the list of threatened or endangered species under the Endangered Species Act (ESA), bald eagles continue to be protected by the Bald and Golden Eagles Protection Act and the Migratory Bird Treaty Act, and are protected as a "sensitive species" within the state of Washington (WAC 232-12-011). The only eagle nests observed near the project site are two nests approximately 0.65 mile from the site on the opposite shore. Mammals: The only wild mammals reported as observed in the area are deer. Fish: Salmonids observed at the site include salmon and trout. Salmonids known to be present in southern Lake Washington include Puget Sound chinook salmon, coho salmon, sockeye salmon, steelhead trout, bull trout and cutthroat trout. Puget Sound chinook, Puget Sound steelhead and bull trout are all listed as threatened under the ESA. Other fish observed at the site include bass, black crappie, bluegill, pumpkinseed sunfish, tench and yellow perch. The shoreline remediation was designed to be consistent with Water Resource Inventory Area (WRlA) 8 Conservation Plan recommendations. As a result of the remediation, shoreline that was previously unsuitable habitat for fish and other aquatic life due to extensive shoreline modifications and industrial use of the site has been restored. The restored gravel substrate and gently sloping bottom should provide favorable habitat for winter rearing of salmon fry. The new gravel substrate to the north and the existing cobble on the subject property should be suitable habitat for benthic invertebrates which would likely attract juvenile salmonids. 7. MEASURES TO PROTECT TREES AND VEGETATION At the present time, the study area has no living woody plant with a trunk six inches or greater in diameter or any other plant falling within the defmition of "Tree" in RMC 4-11-200. This is likely because of the prior asphalt paving over, and industrial use of, the area and subsequent excavation and regrading in accordance with the approved upland development plan. The proposed joint-use pier area has been landscaped pursuant to the general development planting plan. Additional native plants, shrubs and/or trees will be installed in accordance with state and federal project permits. Trees planted in accordance with all landscaping plans will likely have trunks less than six inches in diameter at the time of planting .
