Inc Page 3 ono 1.0 Introduction This report provides results of sediment sampling and chemical testing of sediments in conjunction with proposed Maintenance Dredging. The purposes of this sampling and analysis program are: (l) to chemical collect data regarding the level(s) of contamination that mayor may not be present within sediments of the permitted dredge area; and (2) to assess the suitability of dredged materials for open-water disposal. The purpose of the proposed dredging is to maintain navigational and recreational access. As currently permitted, we anticipate approximately 2500 to 2700 CY of material will be dredged in 2017 based on 2016 hydrographic data. Site History -Historical Dredging The project area (see Figure I-I) has been dredged for many decades. In recent history, the area was dredged in 1994, 1997,2001/2002 and 2011. The boathouse was constructed in the 1950's, and has been in continuous use. A portion of the Barbee Boathouse Navigational Dredge area was last dredged in 2011, concurrent with boathouse renovation under USACE Permit Reference #NWS-2007-1 0 19.

Quendall Terminals is a CERCLA (superfund) site managed by EPA. Primary contaminants at this site are creosote residues (PAH compounds) and petroleum hydrocarbons. Barbee Lumber Mill operations occurred north of the May Creek Delta, and south of Quendall Terminals. Lumber mill operations were essentially shut down in 1999. The boathouse area has been periodically dredged since the early 1950's to maintain navigational access to the boathouse. There is no record of spills or other discharges impacting sediments in the proposed dredge area although low levels of petroleum hydrocarbons were detected during sampling and chemical analysis in 2008. Sediments in the proposed dredge area arise principally from deposition during severe storm events (high energy) when sediment loadings carried from the May Valley Drainage Basin are substantial. Sediments to be dredged in the future are derived from depositional events that have occurred at the May Creek Delta for many years. The project proponents seek to dredge depositional sediments that have infilled the navigational access to the boathouse. The Barbee Company has secured all permits to dredge the area from the USACE and is currently updating permits from state and local jurisdictions. As permitted by USACE, our proposal is to dredge the permitted profile approved by USACE. This profile will not reach depths that will encounter sediments that are older than dredging work completed in 2011 or in previous dredging events. In all respects we will not be dredging to depths that at or below 10-12' elevation (MSL, Corps Datum). In 2002 the depth at the western edge of the dredge footprint was approximately 15-20 feet deep, well below proposed dredge profile. In 2005, for example, the water depth at the Eagle Roost (also periodically referred to the Osprey Nest) was approximately 10' (12' El. MSL). Since 2005, there has been over 10' of depositional infill from on going erosional events. While the numbers are not well developed, the volume of material deposited in Lake Washington at the May Creek Delta is at least 25,000 CY (and likely substantially higher). The point is that the project proponents are not dredging older lake bed sediments by any means. We are simply looking at dredging the least amount of depositional material possible to maintain access to the boathouse, boat ramp, and shoreline access for protected recreational uses. The proposed depth profile for dredging will occur within recent infillideposition. These results are also to be considered a supplement to previous sediment sampling and analysis work conducted in 2007 (reported in 2008) and years prior (see Attachment D -Historical Summary Data Summary). Sediment Sampling Results -Summary Detected chemical contamination in the permitted dredge area (DMMU-l) is very limited. Testing results are below DMMP fresh water and marine screening levels for all parameters (see Section 3.0 Chemical and Physical Data). Nevertheless, some motor oil range petroleum hydrocarbon was detected at 39 mg/kg (dry basis). Diesel Page 5 of 30 range petroleum product was detected in the composite sample at 8.3 mg/kg (dry basis). Additionally, traces of Polynuclear Aromatic Hydrocarbons (PAHs) were detected. For example, benzo(a)pyrene was detected at 24 ug/Kg (dry basis). Suitability of Dredged Material for Open Water Disposal All data indicate that detected chemical contamination levels are below all low-level screening criteria, and that the materials are acceptable for disposal at a DMMP open- water disposal site.

Sediment samples were collected, compo sited and preserved for next day delivery to Analytical Resources, Inc. (Seattle, W A). This section provides a summary of sediment sampling information. Sediment Sampling Logs are provided in Attachment A. Sample Stations Differential GPS was utilized to locate sediment sample stations. Sampling occurred close to proposed locations as moderated by observed field and gusty weather conditions. Sampling locations are summarized in Table 2-1 below. All data was collected using North America Datum (NAD83-Washington North). Lake Elevation at the time of sampling was provided by the USACE at Chittenden Locks. Lake elevation was 20.6 feet (MSL), approximately 1.2 feet below the Ordinary High Water Line (OHWL).

MSL (USACE Datum) Sampling Equipment Samples SED-I and SED-2 were collected as drive samples using a gravity corer from University of Washington. Sample recoveries were generally very good fro Sample SED-2(> 70%) as shown in Sediment Sampling Logs provided in Attachment A. However, recovery at SED-I was poor due to nature of materials sampled. The middle section of the drive met little resistance, and it is believed that we hit a homogeneous loose sandy layer that was lost with extraction of the gravity corer. A repeat drive was conducted with the same results. At no time did it appear that we hit a hard substrate such as might be anticipated in a lake bottom. Because of the consistency of core results (mostly fine 10 medium sand) all sediments appear to [.hl\'d & ASSOCiates.

Because of the shallow sampling thickness, SED-3, was collected with a small vanVeeen sampler with 100% recovery. Sediment Sampling Stations are shown in Figure 2-1. Figure 2-1: Sediment Sampling Stations (Proposed and Actual) Field Sampling Procedure Because of the recent substantial deposition (arising from May Creek), sampling was accomplished by walking out to the sampling locations with the exception of the boathouse sample (SED-3) which was collected just outside the boathouse from an adjacent float. Depth to mudline (something of a misnomer, since no mud was encountered) was measured with a weighted line. The 8' gravity corer included a 24" extension with an added drive weight. The sampler was generally easily extracted and raised out of the water. The only problem encountered with sampling recovery occurred at SED-l where we hit a pocket of low resistance, believed to be homogeneous sandy materials. Sediment cores at SED-I and SED-2 had low water content when extracted. Once extracted from the lined sampler, the sample core was visually inspected and logged. Core contents from within the dredge profile were retained in individual stainless steel bowls. Mixing of the core contents was with a clean stainless steel spoon. No attempt was made to select layers or otherwise alter the sample contents. Equipment Decontamination Prior to sampling, all sampling equipment was decontaminated by scrubbing with a dilute solution of Alconox, rinsed with tap water, and then followed by two rinses of distilled water. In the field, the samplers were rinsed with lake water and visually inspected prior to moving to the next sampling station. A solvent rinse was not utilized at any time.

The composite was weighted 45% each of SED-I and SED-2, and 10% of SED-3. It is unlikely that dredging will occur at the boathouse (SED-3) in the near future because recent sediment deposition patterns to the west predominate, and there is currently adequate navigational depth. A pre-cleaned stainless steel bowl and spoon was utilized to composite samples. Portions were well mixed to a homogenous consistency. The composite sample was identified as 07042016/SED-C. Chain-of Custody The laboratory provided chain of custody was utilized to record basic sample information and requested analyses. All samples were labeled, bagged in Ziploc bags, chilled with ice, and delivered to the laboratory the next day under chain of custody. A copy of the Chain of Custody is provided in Attachment C. Grain Size Distribution Logs I Field Observations Sediment Sampling Logs are provided in Attachment A. In general, sediment sampling yielded good recoveries because of the cohesive nature of the sediment in the sampling profile. However, recoveries at SED-! were marginal as the lower portions of the core were lost during sampler extraction. Grain Size Data is provided in Table 2-2 and graphically presented in Figure 2-2. These sands appear to be relatively recent origin and do not suggest that sediments below the proposed dredge profile were encountered. Sediments from SED-l and SED-2 were odor free and no apparent sheen was observed in any grab sample although a light stringy sheen was observed in SED-3. A transient "rotten" smell was also noticed in SED-3 The upper few inches of each core was layered with coarse sand and pebbles with the exception of SED-3 which had twigs, leaf litter, and mil foil stringers. Milfoil distribution was extensive throughout shallow waters. However, in those areas of recent sediment deposition, the surface was bare of vegetative growth as observed at SED-l and SED- 2 Sampling Stations. All samples, as collected, were sandy and gritty to the touch.

The composite sample was analyzed for both conventional parameters, and the measurement of concentrations of chemicals, which have been identified by DMMP as chemicals of concern (COCs). EPA Analytical Methods were utilized to provide low level detection limits for COe's. A rinsate sample was not collected, as recommended by USACE/DMMP. As provided in the Draft Sampling and Analysis Plan, I the sediment samples, as a composite was submitted for chemical analysis for the following parameters: • Conventional Parameters -EPA/PSEP Methods • Semi-Volatile Organics -EPA 8270D GC/MS (8270D SIM to achieve the required screening level for 2,4-Dimethylphenol) • Total Metals -EPA 200.8; (Except as noted).2 • Pesticides/PCBS -EPA 808118082 GC/ECD • Total Petroleum Hydrocarbons -NWTPH-D • Dioxins/Furans by EPA 1613B Sample containers, preservation, holding times (extraction/time to analysis) were acceptable and in compliance with accepted PSEP protocols. Conventional Testing Results Composite Sample 07042016/Barbee-C was analyzed for Total Solids, Preserved Total Solids, N-Ammonia, Total Sulfides, and Total Organic Carbon. These results are provided in Table 3-1 at the end of this section. Laboratory report forms for this data are provided in Attachment C. Hexavalent Chromium was not detected, reported by ARI as a conventional parameter. Total solids were reported at 80.5% and Total Organic carbon was reported at less than 0.2%. These results are consistent with field observations of well draining sands and gravels with only traces of organic matter. There are no Marine or Fresh water screening levels for conventional parameters. Ammonia levels were detected at 19.6 mg-N/Kg (dry basis), Total Sulfide was reported at 1.8 mg/Kg (dry basis). ~ Draft Barbee Sediment Sampling and Analysis Plan.

Surrogate recoveries met EPA method recovery limits/action criteria for all surrogates Standard Reference recoveries were acceptable and met laboratory acceptance criteria. Method blank results were at or below reporting/detection limits. Spike recoveries gave acceptable precision, and spike duplicate analyses indicated acceptable accuracy. All data reported in Table 3-6 for petroleum hydrocarbons is acceptable as reported. Dioxins and Furans Analysis was performed using the application specific RTX-Dioxin 2 column, which has a unique isomer separation for the 23 78-TCDF, eliminating the need for second column confirmation. Initial calibration and continuing calibration verifications were within method requirements. However, the initial calibration verification fell outside the control limits low for 13CI2-2,3,7,8-TCDF, I3CI2-1,2,3,4,7,8-HxCDF, and 13CI2-1,2,3,6,7,8-HxCDF. All other compounds were within control limits. Both extraction and cleanup surrogates had recoveries within control limits, and the method blank contained reportable responses for several compounds. "8" qualifiers were applied to associated results that were less than ten times the levels found in the method blank. The laboratory control sample gave percent recoveries were within control limits. The PSR SRM (SRM-072116) was analyzed as a reference material. Specific results have been flagged "EMPC", indicating a response not meeting all requirements of positive identification. The EM PC values were treated as undetects. Llo)d & ASSOl'l<.lteS. Ille Page 22 of 30 5.0 Conclusions and Recommendations Sediment Sampling Sampling work conducted at the Barbee Navigational -Maintenance Dredging area was informative. Prior to sampling we had anticipated that medium to course sandy materials would be encountered based on previous experience. Portions of the proposed dredge area outside of the boathouse were most recently dredged in 20 II and previously in 2002. Depositional infill sediments. currently within the proposed dredge profile. tend to be finer sediments unsuitable for shallow water fish habitat enhancement along the rockery to the immediate south. Therefore, all dredged materials will be disposed in open water. Core sampling in sandy sediments was marginal at best at SED-J where recoveries were low at 37.5% Nevertheless. we arrived on site with a number of sampling devices. The gravity corer worked out reasonable well, and the vanVeen sampler worked great for the shallow sample near the boathouse. However, given the poor recoveries at SED-I, a better choice for sample collection might be a vibrocore sampler where a longer continuous core is desirable. Nevertheless, vibrocore samplers have similar limitations in dealing with fine sands, as were encountered at the project site. Based on our experience in sampling conditions encountered, it is not clear that a vibrocore sampler would have worked out better. Because actual proposed dredging depths are relatively shallow and generally less than 10 feet, additional sampling data seems unnecessary although a Z sample could be collected for conformational analyses. At no time will dredging reach former lake bed elevations as dredged in 2002 or 20 II. [n major part the growth of the May Creek Delta severely limits the steepness of slopes that can be sustained within the project area. There are also financial considerations. The project proponent is not interested dredging to the maximum that may be possible. The purpose is to maintain navigational access, not see how much money can be spent to restore historical lakebed elevations in Lake Washington. Sediment Sampling Results -Summary Detected chemical contamination in the permitted dredge area (DMMU-I) is very limited. Testing results are below DMMP fresh water and marine screening levels for Lloyd & As~m:idtt's. Illc Page 23 of 30 all parameters (see Section 3.0 Chemical and Physical Data). Nevertheless, some motor oil range petroleum hydrocarbon was detected at 39 mg/kg (dry basis). Diesel range petroleum product was detected in the composite sample at 8.3 mg/kg (dry basis). Additionally, traces of Polynuclear Aromatic Hydrocarbons (PAHs) were detected. For example, benzo(a)pyrene was detected at 24 ug/Kg (dry basis). Based on Analytical Testing Data and Screening Level comparisons, sediments to be dredged in 2017 at the project site are suitable for open-water disposal. Llmd & i\sSO"18ll'~.

Suite 16 Bellevue. Wa.shington 98005 (425) 747~561X FAX (425) 747~8561 January 14, 2010 JN 10004 via email This report presents our geotechnical observations and conclusions related to design of the anchor piles to be installed for the new Cugini boathouse. The scope of our services consisted of exploring site subsurface conditions, and then developing this report to provide recommendations for design of the piles to withstand lateral loading conditions. This work was authorized by your acceptance of our proposal, P-7895 dated December 2, 2009. Based on our discussions with you, the existing boathouse, which is supported on driven timber piles, will be replaced with a floating boathouse The existing boathouse and its supporting piles will be entirely removed as a part of this work. The new boathouse will be approximately the same size, and will be close to the existing location, possibly a few feet further toward the west. Anchor piles consisting of driven steel pipes will be installed to laterally restrain the boathouse against wind and impact loads. Collars around the piles will allow the boathouse to rise and fall with the approximate 2-foot seasonal fluctuation in the level of Lake Washington. Excavation of the lake bottom will likely occur at the eastem, shore side of the boathouse, where the water depth is only a few feet. SITE CONDITIONS SURFACE The Vicinity Map, Plate 1, illustrates the general location of the site. The existing boathouse is located on the eastem shore of Lake Washington, just north of the existing residence having an address of 4011 Wells Avenue North This metal structure is supported over Lake Washington on timber piles. A wood dock also supported on driven timber piles extends over the shallower water along the north side of the boathouse. Neither the boathouse or the dock move with the water level in the lake. To the north of the boathouse is the old Barbee Mill property, which is being redeveloped with detached single-family homes. The storm detention pond for this neighboring development is situated on land immediately north of the dock. At the time of our field explorations on January 7, 2010, the level of Lake Washington was low. Based on review of the Corps of Engineers' website (www.nwd-wc.usace.army.mil) the elevation of the water surface in Lake Washington typically varies between a maximum of 22 feet in mid- Uoyd & Associates, Inc. January 14.2010 IN 10004 Page 2 summer and 1.95 to 20 feet in winter. The monitoring stations at Kenmore and the Ballard Locks showed a lake elevation of approximately 20.2 feet and 20.0 feet, respectively on the day of our field explorations. These elevations are based on the Corps of Engineers' datum. Infomnation reg arding seasonal and recent lake levels is included as an appendix to this report. The lake bottom is relatively shallow underneath the northern side of the dock, but deepens quickly to the south toward the boathouse. At the boring location, the lake bottom was at a measured depth of approximately 13 inches below the current level of the lake. This would result in a lake bottom elevation of approximately 19 feet at the location of the exploration. Measurements taken by Lloyd and Associates indicate that the current water depth at the western, outboard end of the boathouse is approximately 8 feet. Currently, the water depth at the eastern end of the boathouse is less than 3 feel. SUBSURFACE The subsurface conditions were explored by drilling a single test boring at the approximate location shown on the Site Exploration Plan, Plate 2. The drill rig was set up on the western end of the existing wood dock that is located immediately to the north of the current boathouse. The boring was drilled on January 7, 2010 using a small track-mounted hollow-stem auger drill. Samples were taken at approximate 5-foot intervals with a standard penetration sampler. This split- spoon sampler, which has a 2-inch outside diameter, is driven into the soil with a 140-pound hammer falling 30 inches. The number of blows required to advance the sampler a given distance is an indication of the soil density or consistency. A geotechnical engineer from our staff observed the drilling process, logged the test boring, and obtained representative samples of the soil encountered. The Test Boring Log is attached as Plate 3. Depths on the log are measured from the lake bottom at the drill ing location. The soil encountered to a depth of approximately 5 to 6 feet below' the lake bottom conSisted of very loose, slightly gravelly sand. A piece of chain link fencing became wrapped around the auger within this soil, indicating that this soil may be old fill. We next observed very loose sand that contained lenses of organiCS and sandy sm. This soil unit, which extended to a depth of approximately 18 feet, is likely old lake sediments. Dense, slightly gravelly, silty sand was then encountered between 18 feet and the bottom of the boring at a depth of 34 feet. The sand soils encountered to a depth of approximately 18 feet were wet in the samples and are probably saturated from the over1ying lake. The dense soil beneath was not as wet, but it was not possible to detemnine if it is saturated. The stratification lines on the log represents the approximate boundaries between soil types at the exploration location. The actual transition between soil types may be gradual, and subsurface conditions can vary away from the exploration location The log provides specific subsurface infomnation only at the location tested. If a transition in soil type occurred between samples in the boring, the depth of the transition was interpreted. Lloyd & Associates, Inc January 14. 2010 CONCLUSIONS AND RECOMMENDA TIONS IN 100()4 Page 3 Large-diameter steel pipe piles appear suitable to support lateral loads from the planned floating boathouse. These piles can be installed using either vibratory or impact hammers. Even though the piles will not be subjected to any appreciable vertical loading, it is still important that they be embedded into dense soils. This is necessary to maximize lateral load resistance and prevent vertical settlement under any axial loads that may be transferred to the pile. To achieve this, we recommend that the piles be embedded at least 15 feet into the dense soil. This would require a pile tip elevation of approximately ·15 feet, based on the Corps of Engineer's datum. For rough calculation of the maximum allowable lateral load for a pile, the allowable passive resistance for the very loose soils can be assumed to be provided by an equivalent fluid unit weight of 90 pounds per cubic foot (pet). This passive resistance acts on 1.5 times the diameter of the pile. The passive resistance is not mobilized into the dense soils further down along the pile. USing this method of calculation, an allowable lateral capacity of 23,000 pounds results for an l8·inch· diameter pile. The pile diameter that will be chosen will likely depend largely on the deflection that will result from lateral loading at the collar. The unsupported length of the pile has the most Significant impact on the lateral deflection of a vertical pile under loading. Using the current maximum 8-foot water depth at the boathouse, a maximum l0-foot water depth would be present when the lake level rises in summer. We expect that the collar encircling the pile will be 2 to 3 feet above the lake's surface, yielding an unsupported design pile length of approximately 13 feet. In order to assist with pile sizing, we completed an LPile analysis for both an 18-inch and 24-inch diameter steel pile having a pile wall thickness of 0.5 inches. We applied a lateral load of 11,000 pounds to the pile, which is a preliminary load estimated by B & T Design and Engineering for a single pile. Under this loading, the LPile analysis yields a top of pile deflection of approximately 2.8 inches and 1.4 inches for an l8-inch and 24-inch pile, respectively. Considering the potential variability in the upper, looser soils and the potential for repeated loading, it appears that a 24·inch pile would be more appropriate for at least the western end of the boathouse, where the water depth will be the greatest.

Summary hydrographs are a family of graphs which sho ......... for each day of the calendar year, the maximum, minimum, and average water surface elevatiun over the period of record. 2. Lake Washington water surface data were collected at eight am each day, 3. The Lake Washington Ship Canal is operated prnnarily as a navigation facility connecting Puget Sound and Lakes Union and Washington. Project authorization documents state that under nonnal operation the Lake Washington Ship Canal should be maintained within a 2-foot range between 20.0 feet and 22.0 feet (Corps of Engineers Datum). respectively. The minimum elevation is maintained during the winter months to aUow for annual maintenance on docks. walls, etc .. by businesses and lakeside residents, minimize wave and erosion damage during winter stonns and provide storage space for high inflow. The storage betv.reen 20 and 22 feet is used to augment Lake Washington Ship Canal inflows for use in operating the locks. the saltwaLer return system, the smolt pa.<;sage nume, and the fish ladder facility. 4. The locks and spillway dam regulate the t:ievalioI1 of Salmon Bay. Lake Union, Lake Washington and the Lake Washington Ship Canal. The level of Lake Washington wa'i lowered ahout 8 feet by the construction of the Lake Wa...;;hington Ship Canal, but it is still the second largest natural lake in the state, with a sunace area or 22.138 acre:; and shoreline of about 91 miles at elevation 22 feel.

The design approved by the City of Renton called for a total of 12 wide-flange beams driven to refusal to carry the new bUilding loads. Six piles were located on each of the north and south sides of the new boathouse. A minimum of 15·foot embedment into dense soils was required by the structural engineer to achieve sufficient vertical capacity and lateral bending reSistance. Representatives from our firm observed the installation of the piles on July 25 through 27, 2011. Pacific Piling utilized a large vibratory hammer to install the H-piles vertically. As required by the plan, galvanized W14x74 beams were installed for the boathouse. Through observation of the penetration rate, we were able to verify that all piles were installed to at least 15 feet of embedment into the dense soils. The pile lengths necessary to reach sufficient embedment increased from east to west, as was expected. Based on our observations, it is our professional opinion that the piles were driven an acceptable manner and reached sufficient embedment into dense soils to support the design loading.

Storag~: SRM 1944 must be stored in its Original bottle al temperatures less than 30'C away from direct sunlight. Us.: Prior to removal of test portions for analysis, the contents of the bottle should be mixed, The concentrations of constituents in SRM 1944 are report~d on a dry-mass basis_ The SRM. as received, contains a mass fraction of approximately 1 J % moisture. The sediment samph:: should be dried to a constant mass before weighing for analysis or, iftbc constituents ofinterestare volatile, a separate test portion of the sediment should be removed from the bottle at the time of analysis and dried to delennine the mass fraction on a dry-mass basis. SRM 1944 Page 2 of 22 PREPARATION AND ANALYSIs''' Sample Collodion and Preparation: The sediment us«! to prepare this SRM was collected ftom si. sites in the vicinity of New York Bay and Newark Bay in October 1994. Site selection was based on contaminant levds measured in previous samples from these sites and was intended to provide relatively high concentrations for a vanety of chtmical classes of conlaminanlS, The sediment was collected using an epo.y·coated modified Van Vecn-type grab sampler designed to sample the sediment to a depth oflO em, A total ofapproximately 2100 kg oCwet sediment was collected from the six sites. The sediment was freeze-dried, sieved (nominally 250 I"" to 61 ~m), homogenized in a con. blender. radiation sterilized at an estimated minimum dose of32 kilograys ("Co), and then paCKaged in screw-capped amber glass holtles. Conversion to Dry-M ... Basis: The result. fur the constituents in SRM 1944 are reported on a dry-mass basis; however. tbe material as received conlain. residual moisture, The amount of moisture in SRM 1944 was determined by measuring the mass loss after free .. drying test portions of 1.6 g to 2.5 g for five duys.t 1 Po with a -10°C .helf temperature and a-50°C condenser temperature, The mass fraction of moisture in SRM 1944 at the time of the certification analyses was 1.25 % ± 0.03 % (95 % confidence level). Polycyclie Aromatic Hyd ...... rbons: The general approach used for Ibe value assignment of the PAHs in SRM 1944 consisted of combining results from anal yses using various combinations of different extraction techniques aoo solvents. cleanUp/isolation procedures, and <hromatograpbic separation and dete<:tion techniques [2). Te<:hniques and solvents involved were Soxhlej extn!ction and pressurized fluid extracrion (PFE) using dichloromethane (DCM) or a hexane/acetone mixlure~ clean up of the extracts using solid-phase exnaction (SPE). or nonnal-phase liquid chromatography (LC). followed by analysis using tbe following techniques: (I) reversed-phase liquidcbromatography with fluorescence detection (LC-FL) analysis ofth. total PAH fraction. (2) revers<d-phas. iC-FL analysis ofisameric PAH tractions isolated by normal-phase LC (i.e., multidimensional LC), (3) gas chromatographylrnass spectrometry (GClMS) analysis of the PAH fraction on four stationary phases of different sele<:tivity, i.c" a 5 % (mole fraction) phenyl-substituted methyipolysiloxlUle phase. a 50 % phenyl-substituted methylpolysilox.ne ph .... a proprietary non-polar polysiloxane phase, and a smecric liquid crystalline stationary phase. Seven set. of GClMS results. designated as GClMS (I), GCIMS (II). GCIMS (Ill), GCIMS (IV), GCIMS (V), GClMS (VI), and GC/MS (Sm). were obtained using four columns with different selectivities for the sepa!1Ition of PAHs. For GeIMS (I) analyses, duplicate test portions ofl g from eight bottles ofSRM 1944 were Soxhlet extracted for 24 h with DCM, Copper powder was added to the extract to remove elemental sulfur. The concentrated extract was passed through a silica SPE cartridge and eluted with 2 % DCM in bexane. (All extraction and LC solvent compositions are expressed as volume fractions unless otherwise noted.) The processed extrac( was then analyzed by GCIMS using a 0.25 mm i.d. " 60 m fused silica capillary col= with a 5 % phenyl·substituted methylpolysiloxane phase (0.25 ~m film thickness) (DB-5 MS, J&W Scientific. Folsom. CAl. The GCIMS (11) analyses were performed using I g to 2 g test portions from three boltles ofSRM 1944 and 2 g to 3 g test portions from three bonle.s ofSRM 1944 that had been mixed with a similar amount or water {i.e., a welted sediment), These test portions were Soxhle1 extracted with DCM and pcocessed through the silica SPE as described above: however, the .xtract was further fractionated using normal-phase LC on a semi-preparative aminopropylsiJane column to isolate the PAH fraction. The PAH fraction was then analy<ed using the same column as destribed above for GefMS (I); however, the tesl ponions were extracted, processed, and analyzed as part of three different sample sets .t different times using different calibrations for each set. For the GClMS (lH), I g to 2 g test portions from six hollIes of SRM 1944 were Soxhlct extracted for 18 h with 250 mL of a mixture of 50 % hexanel50 % acetone. The extracts were then proces.ed and analy .. d .. described for GCIMS (II). For GClMS (IV) analyses. I g to 2 g test portionsfrom six bottles ofSRM 1944 were extn!cted using PFE with a mixture of SO % bexane/50 % acetone, and the extracts were processed as described above for GCIMS (II), The GCIMS (V) results were obtained by analyzing three of the same PAH fractions that were analyzed in GC/MS (III) and three of the PAH fractions that were analy.ed in GeIMS (IV) using a SO % (mole fraction) phenyl-substituted methylpolysiloxane stationary phase (0.25 mm Ld, x 60 m. 0.25 ~m film thickness) (DB-17MS, J&W Scientific, Folsom, CAl, For GClMS (VI) analyses. three test portions ofO,7 g from one bailIe ofSRM 1944 were Soxhletextracted for 24 h with DeM. Copper powder was added to the extract to remove elemental sulfur, The conc-enlraled extract was passed through an aminopropyl SPE cartridge and eluted with 20 % DCM in hex.ne. The pcoce"ed extract was then analyzed by GC/MS using a 0.25 mm i,d. x 60 m fused silica capillary column with a propcietary non-polar polysiloxane phase (0.251'1l1 film thickness) (DB-XLB, J&W Scientific), For GCIMS (Sm) I g to 2 g test portion, from six bottles of SRM 1944 were Soxhlet extracted for 24 h with 250 mL ofDCM, The extracts were processed as described above for (It::ertAin commercial equipment, instruments. or materials are identified in Ibis report to adequately specify the experimental procedure.

Two set, ofLC-FL results, designated as LC·FL (Total) and LC·FL (Fraction), were used in the certification process. Test portions of appro,imately I g from six bonles ofSRM 1944 were S"hlet extracted for 20 h using 200 mL of 50 % hexane/SO % acetone. The extracts were concentrated and then processed through two aminopropylsilane SPE canridges connected in series to obtain tbe total P AH fraction. A second I g test portion from the six bottles was Soxhlet extrncted and processed as described above; the PAH fraction was then fractionated further on a semi-preparative aminopropylsilane column (flBondapak NH" 9 mm i.d. x 30 cm, Waters Associates, Milford, MA) to isolate isomeric PAll fractions. The total PAH fraction and the isomeric PAH fractions were analyzed using a 5·1U'l particle·size polymeric octadecrlsilane (C,,) column (4.6 mm i.d, x 25 em, Hypersil.PAH, Keystone Scientific, inc., Bellefonte, PAl with wavelength-programmed fluorescence detection. For all of the GCIMS and LC-FL mea,urement, described above, selected perdeuterated PAHs were added to the sediment prior to solvent extraction for use as internal standards for quantification purposes. Homogeneity A ........ entfor PAHs: The homogeneity ofSRM 1944 was .. """,,,sed by analyzing duplicate lest portions of I g from eight bottles selected by 'tmtified random sampling. Test portions were extracted, processed, and analyzed as described above for GC/MS (1). No statistically significant differences among bottles were observed for the PAHs at the I g test portion size. PAH 150men of Molecular Mus 300 and 301: For the detennination of the molecular mass 300 and 302 PAH isomer5~ three test portions of approximately 5 g each were extracted using PFE with DCM. The extracts were then concentrated with a solvent change to hexane and passed through an aminopropyl SPE cartridge and eluted with 10 % DCM in hexane. The processed extract w •• then analyzed by GClMS using. 0.25 mm i.d, x 60 m fused siliclcapillary column with a 50 % phenyl·,ub,titued methylpolysiloxane phase (0.25 ~m film thickness; DB-I 7MS, 1& W Scientific, Folsom, CAl. Perdeuterated dibenzo[a,rJpyrene was added to the sediment prior to extraction for usc as an internal standard. PCBo and Chlorinated Pesticides: The general approach used for the determination of PCBs and chlorinated pesticides in SRM ]944 consisted of combining results from analyses using various combinations of different extraction techniques and solvents, cleanup/isolation procedures, and chromatographic separation and detection techniques (2]. This approach consisted ofSoxhlet extraction and PFE using DCM or a hexane/acetone mixture, clean up/isolation using SPE or Le, followed by analysis using GCIMS and gas chromatography wilb electron capture detection (GC·ECD) on two columns with different selectivity, Eight sets of results were obtained designated as GC·ECD (I) A and B, GC·ECD (II) A and B. GCIMS (I), GClMS (II), GC/MS (III), and QA Exercise. for lbe GC-ECD (I) analyses, I g test portions from four bonles ofSRM 1944 were Soxhlet extracted with DCM for 18 h. Copper powder was added to the extract to remove elemental sulfur. The concentrated extract was passed through a ,i lica SPE cartridge and eluted with I 0 % DCM in hexane. The concentrated eluant was then fractionated on a semi-preparative aminopropylsilane column to isolate two fractions containing: (I) tbe PCBs and lower polarity pesticides and, (2) the more polar pesticides. GC-ECD analyse. of the two fractions were performed on two columns of different selectivities for PCB separations: 0.25 mm x 60 m fused silica capil1ary column with as % phenyl-substituted methylpolysiloxane phase (0.25 ~ film thickness) (DB-5, J&W Scientific, Folsom, CAl and a 0,32 mnt x 100 m fused silica capillary column with a 50 % (mole fraction) octadecyl (Cl8) methylpolysiloxane phase (0.1 ~m film thicknessHCPSil 5 C 18 CB, Chrompack International, Middelburg, The Netherlands). The result, from the S % phenyl phase are designated as GC·ECD riA) and the results from the CI8 phase are designated as GC·ECD (IB). A second set of samples was also analyzed by GC·ECD (i.e., GC·ECD IIA and U8). Test portions of I g to 2 g from three bottle, of SRM 1944 and 2 g to 3 g test portions from three bottles of SRM 1944 that had been mixed with a similar amount ofwaler (i.e., a wetted sediment) w~re extracted, processed. and analyzed as described above for GC· ECD (I); however, tbe test portions were extracted, processed and analyzed as part of three di fferent sample seto at different times using different calibrations for each set. SRM 1944 Page 4 of22 5;';",i 1000:22 Three sels of resuhs were obtained by GCIMS, For GCIMS (I), I g to 2 g test portions from six boltle< were Soxhle, eXlraCted with a mixture of 50 % hexane/50 % acelone, Copper powder was added to the extract to remove elemental sulfur. The concentrated extract was passed through a silica SPE cartridge and eluled with 10 % DCM in hexane. The extract was then analyzed by GC/MS using a 0.25 mm x 60 m fused silica cap~lary column with a 5 % phenyl-substituted m<thylpolysiloxane phase (0,25 ~m film thickness). The GC/MS (II) results were obtained in the same manner as the GCIMS (I) analyses except that the six test portions were extracted using PFE. The GCIMS (III) analyses were performed on the sarne extract fractions analyzed in GC-ECD (Il) using the 5 % phenyl-substituted methylpolysiloxane phase describe above for GClMS (I). For both the GC-ECD and GCIMS analyses, two PCB congeners Ihat are 001 significantly present in the sedimenl extract (PCB 103 and PCB 198 (3]), and 4,4'-DDT -d, were added to Ihe sediment prior to extraction for usc as internal standards for quantificalion purposes, In addition to the analyses performedal NISr, SRM 1944 was used in an interlaboratory comparison exercise in 1995 as part ofthe NISr Intercomparison Exercise Program for Organic Contaminants in the Marine Environment [4], Resuhs from nineteen laboratories that participated in this exercise were used as the eighth data set in the detennination of the certified values for PCB congeners and chlorinated pesticides in SRM 1944. The laboratories participating in this exercise used the analytical procedures routinely used in Iheir laboratories to measure PCB congeners and chlorinated pesticides. Polybrominated Dlphenyl Etbers: Value assigrunent ofth. concentrations of eight PBDE congeners was based on the means of results from two interlaboratory studies [5,6) and two sets of data from NIST. The laboratories participating in the interlaboratory e.ereises (sec Appendix A) employed the analytical procedures routinely used in their laboratories to measure PBDEs, For the two methods used at NIST, six test portions (between 1 g and 2 g) were extracted using PFE at 100°C with DCM, The extracts were cleaned up using an alumina column (5 % deactivated) SPE wlumn, Siz< exclusion chromatograpby (SEC) 011 a divinylbenzene-polystyrene column (10 ~ particle si .. , 10 nmCIOO angstrom)poresize, 7.5 mm i.d, x 300 mm, PL-Gel, Polymer Labs, Inc.) was then used to remove the sulfur. The PBDEs, as well as PCBs and pesticides, wmquantified usingGCIMS in the electron impactmodeonaO.18 mmi.d, , 30 m fused silica capillary column with a 5 % (moleflaction) phenyl methylpolysiloxane phase (0, 18 ~ film tlric1m ... ; DB-5MS.

Analytlcal Approach for Inorganic Constituents: Value assignment for the concentrations of sel""ted trace elements was accomplisbed by combining resuhs of the analyses ofSRM 1944 from NIST, NRCC,IAEA, and seven laboratories that participated in an interlaboratory comparison exercise coordinated by NRCC (7] (see Appendix C). Th. analytical methods used for the determination of each elemenl are summarized in Table 18. For the cenified concentration values listed in Table 4, results were combined from: (I) analyses at NIST using isotope dilution inductively coupled plasma mass spectrometry (ID-ICPMS) or instrumental neutron activation analysis (rNAA). (2) analyaes at NRCC using ID-ICPMS, graphite fuma« atomic absorption spectrometry (GFAAS), and/or inductively cuupled plasma optical emission spectroscopy (ICPOES), (3) analys.s at IAEA using INAA' and (4) the mean of the results from seven laboratories that participated in the NRCC interlaboratory comparison exercise. The reference mass fraction values in Table 9 w~re determined by combining results from (I ) analyses perfonned at NIST using INAA; (2) analy.es at NRCC' using ID-ICPMS, Gf AAS,ICPOES, andlorcold vapor atomic absorption spectroscopy (CV AAS); (3) analyses at IAEA using INAA; and (4) the mean of the results from five to seven laboratories that participated in the NRCC interlaboratory comparison exercise. The information ooncentration values in Table 15 were det.nnined by INAA at NIST and IAEA. NIST Analyses using II).ICPMS: Lead, cadmium, and nickel were determined by ID-ICPMS [8], rest portions (0.4 g 10 0.5 g) from six bottles of the SRM were spiked with 206 Pb. J II Cd, .. oo 6:!Ni and wet ashed using a combination of nitric. SRM 1944 Page 5 of 22 SCW i 000?:-=< hydrochloric, hydrofluoric, and perchloric acids. Lead and cadmium were detennined in the same test portions; nickel was delcnnincd in a second sample set. A small amount of crystalline material remained after the acid dissolution. Lithium metaborate fusion was performed on this residue to confinn that the residue contained insignificant amounts of the analytes. Cadmium and nickel were separated from the matrix material to eliminate the possibility of spectral inrerferences, and concentrations were detennined from the measurement of the 11:!Cdl tll Cd and b.2 N ifONi ratios, respectively. The ""'Pb/""'pb I1Itios were measured directly because interferences at these masses are negligible. NIST Analyse. using INAA: Analyses were perfonned in two steps [9). Elements with shon-lived irradiation produets (AI, em, Cl, K. Mg, Mn, No, Ti, and V) were determined by measuring duplicate 300 mg test portions from each of ten bonles of SRM 1944. The samples, standards, and conlTo), were packaged in clean polyethylene bags and were individually irradiated for 15 s in the NJST Reactor Pneumatic Facility RT-4. Reactor power was 20 MW, which corre'pondSlo a neutron fluence rate ofabout 8 x \0 13 em'" s' '. After inadiation, the samples, controls, and stondards were repackaged in clean polyethylene bags and counted (gamma-ray spectrometry) three limes at different decay intervals. A sample-to-detector distance (countiDg geometTY) 0[20 cm was used. Elements with long-lived i""diation products (Ag, As, Br, Co, Cr, Cs, Fe, Rb. Sb, So. Se, Th, and Zn) were determined by mea,uringone 300 mg test portion from each of nine bottles of SRM 1944. The samples, standards, control., and blank polyethylene bags were irradiated together for a total of] h at a reactor powerof20 MW. Approximately four days after irradiation, the polyethylene bags were removed, and each sample, standard, control. and blank was counted at 20 em from the detector. The samples were then recounted at 10 em from anolher delector. After an additional decay time of about one month, the samples. standards, controls, and blanks were counted a third lime (al 10 em) from the second deteclor. Homogeneity Assessment ror Inorganic Con.lilutenls: For some of the trace elements. most notably Cd. Fe. Pb, Rb, Sb. Sc, and Th, the variations among the test portions measured at NIST (belween OJ g and 0.5 g) were larger than expected from the measurement process. Based on experience. it was ooncluded that there is some material inhomogeneity for trace elements in the test portions used. Sample variations arnol'lg the NIST measurements are used as slightly conservative estimates of the: sample inhomogeneities. Particle Size Informalion: DIy plll1icle-size disuibution measurements for SRM 1944 were obtained as part of a collaborative effort with Honeywell's Panicle and Components Measurements Laboratory (Clearwaler, FL). A Mlcrotrac particle analyzer, which makes use of light-scattering techniques, was used to measure the particle-size distnbution of SRM 1944. Briefly, a reference beam is used to penetrate a field of particles and the light that seallers in the forward direction from the field is measured and the particle 4 size as a volume distribution is derived via a computer-assisted analysiS. From these data, the total volume, average size, and a chartleteristic width of the particle size distribution are calculated. The syslem bas • working range from O. 7 ~m to 700 f1ID. Total Organic Carbon and Percent Extractable Mass: Four laboratories provided results for lotal organic carbon (TOC) using similar procedures. Briefly, test portions of approximately 200 mg were reacted with 6 moVL hydrochloric acid and rinsed with deionized water prior to combustion in a gas fusion furnace. The carbon monoxide and carbon dioxide produced were measured and compared 10 a blank for calculation oftbe percenl TOC. Each laboralory analyzed lest portions from six bonles ofSRM 1944. Forth. determination of percent extraClable mass, six test portions ofapproximately I g to 2 g ofSRM 1944 were extracted using Soxhltt extraclion for 18 h with DeM. Tbe extraction thimbles were allowed to air dry. After reaching constant mass. the difference in the mass before and after extraction was detennined. Polychlorinated Naphlhal ..... : Value assignmenl ofPCN congener concentrations was accomplished by combining resulls from the analysis ofSRM 1944 by six laboratories that participated in an interlaboratory comparison study (see Appendix 0). Each laboratory analyzed three test portions (typically ) g 10 2 g) of SRM 1944 using their routine analytical procedures that included high-resolution gas chromatography with either high-resolution mass spectromeuy detection (GC ~HRMS) or low·resohnion MS in the negative chemical ioniution mode. Calibration mixrures included eitber Halowax mixtures with known volume fractions of ilXlividual congeners or individual PCN congeners. SRM 1944 Page 6 of 22 HBeDs: Value ... ignmenl of the concenlratlons of three HBCD isomers was accomplished by combining results from Ihe analysis ofSRM 1944 in two sel' from NIST and one set from Virginia Institute of Marine Science. For the two sets analyzed at NlST. the second fraction from iill acidifierl silica SPE clean-up was anaiyDXl by LO'MSIMS for the HBCDs using both e1ectrospray ionization (ES!) and almospheric pr=uriud photoionization (APP!). A C 18 column (3.0 mm x 150 mrn x 3.5 ~m column. Eclipse Plus. Agilent Technologies) and YMC Carotenoid SS C30 column (4.6 mm x 250 mm x 5 jUl'I column) were used with a solvent gradient using 2.5 mmoVL ammonium acetate in 12.5 % water in metbaool and acetonitrile at a flow rate of 0.3 mUmin. Carbon-I 3 labelerl HBeDs were adderlto the sediment prior to solvtl1t extrnction for use as internal standards for quantification purposes. Tabl_ I.

The purposes of this sampling and analysis program were (I) to collect sufficient data of adequate quality for decision making purposes regarding the level(s) of contamination that mayor may not be present within sediments of the proposed boathouse dredge area; and (2) to assess the suitability of dredged materials for habitat enhancement. The purpose for proposed dredging at the boathouse is to maintain navigational access and continued recreational use of the boathouse. The project summary. site history. potential site contaminants. and additional information are provided in the Sampling and Analysis Plan (L&AI. 2007) previously submitted to the USACE. The project area is shown in Figure I-I below.

The proposed dredgl.! area (approximale) is ollt/ined in while:' Sediment Sampling Results Summary Detected chemical contamination in the proposed boathouse area (OMMU-I) is relatively limited. Testing results are below both fresh water sediment and marine sediment screening levels for all parameters (see Section 3.0 Chemical and Physical Data). Nevertheless. some motor oil and diesel range petroleum product was detected in the composite sample at 95 mg/kg (dry basis). Benzene was not detected. These 2(j08-50 Barbee Sediment Sampling RCSldtS dol' Page 4 of20 results are consistent with historical sampling and analysis data, and are below MTCA Method A criteria for unrestricted residential land usc. Suitability of Dredged Material for Shallow Water Habitat Enhancement The Barbee JARPA Submittal provided that sediments could potentially be used for habitat enhancement along the rockery face immediately south of the dredge area, if sediment characteristics were suitable and potential contaminant levels were acceptable. Gradation results of sediment sampling (see Section 2.0) indicate that the use of imported clean materials (such as spawning gravel) from an approved WSDOT source would be more appropriate. Sediments to be dredged are typically fine to medium sands and silt that would appear to be more appropriate for upland beneficial uses. Therefore. dredged sediments will not be disposed or placed in open water under the Dredge Material Management Program (DMMP). 20llS-S0 Harbee SedliTIent Smnpllllg Results doc Page 5 of 20 2.0 Sediment Sampling Sediment sampling at the Barbee Boathouse Dredge Area was conducted on Sunday October 21, 2007. As proposed. grab samples were collected. composited and preserved for next day delivery to Analytical Resources. Inc. (Seattle. W A). This section provides a summary of sediment sampling information. Sediment Sampling Logs are provided in Attachment A. Sample Stations Differential GPS was utilized to locate sediment sample stations. Sampling occurred close to proposed locations as moderated by observed lield and gusty weather conditions. Proposed and actual sampling locations are summarized in Table 2-1 below. All data was collected using North America Datum (NAD83-Washington North). Lake Elevation at the time of sampling was provided by the USACE at Chittenden Locks. Lake elevation was 20.6 feet (MSL). approximately 1.2 reet below the Ordinary High Water Line (OHWL).

Under the field conditions observed, the modified Shelby sampler proved to be the most effective coring device. The only modification to the sampler was to adapt extension rods and convert it into a push or drive sampler. Sample recoveries were generally very good (> 70%) as shown in Sediment Sampling Logs provided in Attachment A. The gravity corer worked very well with good penetration, but small sticks and woody debris, commonly encountered on the lakebed surface, tended to reduce the effectiveness of this sampler. Sediment Sampling Stations are shown in Figure 2-1. SCALE (tt) , >C, Figure 2-1: Sediment Sampling Stations Field Sampling Procedure Except in the boathouse, where sampling occurred from the walkway, sampling occurred from the side of a 21' sampling boat. The boat was anchored in position at the sampling station and powered down. Depth to bottom was physically measured with a weighted line. Depth sounding from the vessel's depth meter tended to be very inaccurate because of intense growth of milfoil throughout the proposed dredge area. The Shelby sampler was equipped with a push rod extension(s) to reach the bottom of the proposed depth profile(s). The sampler was generally easily extracted and raised out of the water. The sampler was placed in the bouom of the boat on clean visquine. A light tap on the extension rod andlor sampler casing was all that was required to release the sample. In practice, extreme care was necessary to avoid jostling or banging the sampler during extraction. Sediments from below the proposed dredge profile tended to be coarse sands that were difficult to sample without substantial loss. Because of the difficulty or sampling coarse sands below the proposed dredge profile in a representative manner, a "Z" was not collected. 2008-50 Garhee Sediment Sampling Results doc Page 7of20 Th e grav it y co rer wo rk ed very well in s ide thc boathouse. but s ma ll woody debri s in th e d redge 70 ne te nd ed to dellect the sa mpler o r decrea se th e ene rgy of th e dro p.

Analytical testing results of the decontamination sample are presented in Section 3 -Chemical and Physical Data. The rinsate/decon sample was identilied as 071021 IBarbee/R. Composite Preparation A composite sample was constructed from equal portions of the five (5) individual grab samples. Grab samples were identilied as 071021/Barbee/G-I through (i-5. A pre-cleaned stainless steel bowl and spoon was utilized to composite samples for laboratory analyses. Portions were well mixed to a homogenous consistency. The composite sample was identified as 071021 IBarbee/C. Chain-of Custody The laboratory provided chain of custody was utilized to record basic sample information and requested analyses. All samples were labeled. bagged in Ziploc bags. chilled with ice. and delivered to the laboratory the next day under chain of custody. A copy of the Chain of Custody is provided in Attachment B. Grain Size Distribution Logs I Field Observations Sediment Sampling Logs of the 5 grab samples are provided in Attachment A. Page 6 of the series provides a more complete summary of sample location data presented in Table 2-1 and includes conversion of state plane data into latitude and longitude. In general. sediment sampling yielded better recoveries than anticipated because of the cohesive nature of the sediment in the dredge profile. Below the dredge profile we observed generally coarse sands which were poorly recovered. Grain Size Data for sample 071021 IBarbee/C (composite sample) is provided in Table 2-2 and graphically presented in Figure 2-3. These coarse sands within the proposed over- depth appear to be relatively undisturbed by previous dredging in the area. Sediments were odor free and no apparent sheen was observed in any grab sample although a light stringy sheen was observed rising to the surface at Station BBSE[)-4 when the VanVeen sampler was withdrawn from the sediment. In general the upper few centimeters of each core was layered with leaf litter. twigs. small sticks. milfoil roots and other vegetation. Milfoil distribution was extensive and thick throughout the entire dredge area except within the boathouse footprint where sunlight is extremely limited. 20118-50 Barbee Seuim.:-nt Sampling Result, do( Page 9 of20 Table 2-2 Grain Size Sample: 071021/Barbee/C Description: Composite Sediment Sample DMMU-1 Analytical Method: Grain Size by ASTM 0422 Mesh Inches Microns % Finer 0.0029 74 14.9 0.00588 149 30.6 0.00983 250 54.1 0.01655 420 80.1 0.03306 840 91.7 0.07875 2,000 96.5 0.5 4,750 99.2 #4 0.187 9,525 100 #10 0.375 12,700 100 #20 0.75 19.050 100 #40 1.0 25,400 100 #60 1.5 38,100 100 #100 2.0 50,800 100 #200 3.0 76,200 100 Composite is equal portions of grab samples G-1, G-2, G-3, G-4 & G-5 Grain Size Distribution By ASTM 0422 #100 #20 #4 100 -~ 1 90 I ~I !

Seattle, W A) on ice under Chain of Custody. The composite sample was analyzed for both conventional parameters and the measurement of concentrations of chemicals, which have been identified by DM:vJP as chemicals of concern (COCs). EPA Analytical Methods were utilized to provide low level detection limits for coes. Specialized analyses for Volatile Organic Compounds and Total Volatile Solids were conducted on grab sample 071021 /Barbee/G-I. Rinsate analyses included Total Metals and Semivolatile Organic Compounds. As provided in the Sampling and Analysis Plan,1 the sediment samples (composite and grab where required) were submitted for chemical analysis for the following parameters: • Conventional Parameters -EPA/PSEP Methods • Volatile Organic Compounds -EPA 8260 GUMS • Semi-Volatile Organics -EPA 82700 GUMS • Total Metals -EPA 200.8; (Except as noted) • Pesticides/PCBS -EPA 8081/8082 PSDDA GClECD • Total Petroleum Hydrocarbons -NWTPH-D Sample containers. preservation, holding times (extraction and time to analysis) were acceptable and in compliance with the Sampling and Analysis Plan and accepted PSEP protocols. The rinsate sample (071021/Barbee/R) was analyzed for Semi- Volati Ie Organics and Total Metals. Sediment Analyses Conventional Testing Results Composite Sample 071021 /Barbec/C was analyzed for Total Solids, Preserved Total Solids, N-Ammonia, Total Sulfides, and Total Organic Carbon. Total Volatile Solids were analyzed on grab sample 971021/Barbee/G-1 from the western edge of the proposed dredge area. These results are provided in Table 3-1 at the end of this section.

Prior to sampling we had anticipated that medium to course sandy materials would be encountered based on previous experience. Portions of the proposed dredge area outside of the boathouse were most recently dredged in 2002 during the last May Creek Delta Dredging. Sediments below the proposed dredge profile (within the over-depth) were more typical of what we anticipated. Infill material currently within the proposed dredge profile tends to be finer sediment unsuitable for shallow water fish habitat enhancement along the rockery to the immediate south. Therefore, all dredged materials will be oft:loaded to land of or placed in open water under the Dredge Material Management Program (DM MP). Core sampling in sandy sediments is marginal at best. Nevertheless, we arrived on site with a number of sampling devices. Because of the extensive milfoil and lakebed accumulation of small woody debris (sticks. twigs. leaves), the gravity corer did not prove to very effective. A modified Shelby Tube that was hand driven proved to be very effective with the dredge profile where infill materials tend to be fine sands with appreciable silt content. The VanVeen sampler worked extremely well in limited usc at Sampling Station BBSED-4. This sampler should be ideal for conformational sampling. if required. after dredging. As indicated in Section 2.0. over-depth sediments tend to be much coarser, and core recoveries in the over-depth zone were very poor such that it was not possible to get a representative sample of the over-depth. The over-depth sediments (below the proposed dredge profile) more closely approximated the kind of dredge material anticipated (based on prior experience) prior to sampling. Because dredging has largely been conducted at the former Barbee Millon fairly regular 3-4 years cycles. we were surprised at how much milfoil was encountered throughout the proposed dredge area. If this is typical of Lake 2008-50 Barbe<..' Sediment Sampl ing Results_doc Page 17 of20 Washington. then the problem is more extensive than previously considered by our project team. Chemical Contamination Based on sediment results provided in Section 3.0 of this report. the Barbee Boathouse Dredge Area is remarkably clean. All detected and undetected results were less than Screening Levels for both Marine and Fresh Water. Additionally. all detected and undetected contaminant levels were less than MTCA Method A -Soil Cleanup Levels for Unrestricted Land Use. Like most urban areas, low levels of PAH compounds, as well as, phthalate esters, were encountered. No pesticides or PCBs were detected and concentrations of detected metals were unremarkable. Petroicum hydrocarbon residues (motor oil at 95 mg/Kg-dry, and diesel at 14 mg/Kg-dry) were detected. The presence of motor oil was somewhat of a mystery because no visible sheen was apparent in any grab sample or in the prepared composite sample. Nevertheless. we did observe a stringy streak of oily material at sampling station BBSED-4 ncar the boathouse. This material did not spread into a sheen as might be anticipated. Base on our experience. the stringy material appeared to be decomposed plant material. In any case. the laboratory confinned the spectral match for motor oil in the composite sample. Because of the presence of detected motor oil in the composite sample, the use of dredged sediments containing petroleum hydrocarbons (motor oil and traces or diesel) for shallow water habitat enhancement should not be encouraged. Because detected contaminant levels for all measured chemicals or concern were below screening criteria for marine and fresh water disposal or beneficial uses, further biological testing is not recommended. Recommendations for Confirmational / Future Sampling As soon as an area is dredged in the future. conformational sampling (if required) should be conducted with a VanVeen Sampler in the over-depth profile with testing for petroleum hydrocarbon residues (diesel and motor oil). Operationally this could be accomplished in conjunction with dredging. For example when a reasonably defined area is dredged. such as the boathouse footprint. a sample would be collected and analyzed on a rush basis for NWTPH-Dx to determine whether additional dredging is necessary to remove petroleum hydrocarbon impacted sediments. Observational data of any potential sheen would supplement over-depth sampling and analysis data such that the work can be completed in a timely manner. Based on sediment data collected to date, there is no evidence that sampling and chemical analysis for other potential contaminants of concern is necessary. 2008-50 Barbce Scdl1llcnl Sampling Rcsults doc Page 18 of20 Table 4-1: QA Summary I Conventional Parameters Sample: 071021/Barbee/C Description: Composite Sediment Sample DMMU-1 Varies by Analyte Analytical Method: Quality Assurance Checks Precision 071021/Barbee/C -Duplicate Hexavalent Chromium N-Ammonia Sulfide Total Solids Preserved Total Solids Total Organic Carbon Total Volatile Solids Matrix Spikes 071 021/Barbee/C -Matrix Spike Hexavalent Chromium N-Ammonia Sulfide Total Organic Carbon Laboratory Control Sample Sulfide Total Organic Carbon Reference Materials SRM N-Ammonia (SPEX28-24AS) Total Organic Crbon (NIST 8704) Hexavalent Chrome (SRM) Method Blanks Notes: Hexavalent Chromium N-Ammonia Sulfide Total Solids Preserved Total Solids Total Organic Carbon Total Volatile Solids Meets Warning Limits Criteria?

LAKE STUDY LAKE HOUSES AT EAGLE COVE SEDIMENT DEPOSITION MITIGATION 1.0 INTRODUCTION 1.1 BACKGROUND AND PURPOSE This lake Study was prepared to obtain a 10-year permit from the City of Renton to allow dredging of an expanded area of lake Washington located directly south the May Creek delta (adjacent to the lake Houses at Eagle Cove) (Figure 1; Appendix A). Periodic maintenance dredging is needed at this location to preserve navigational access to the docks and boathouse; and to preserve access for swimming, canoeing, and other water sports. While maintenance dredging to remove accumulated sediments has occurred within and near the May Creek delta for over 50 years, the proposed project addressed in this study is focused on the expanded zone shown in Appendix A', and could entail the removal of as much as 4,000 to 8,000 cubic yards (CY) of sediment every 3 to 4 years, due to increasing volumes of sediment that are delivered to the project area as a result of activities in the upper May Creek watershed. In addition to expanding the dredging prism, the proposed project would involve seven environmental protection and enhancement measures in the local area. These include the following: • Place 20 CY "fish rock'" along the rockery as well as several yards of fish rock adjacent to the boat ramp on lot A; • Replace a solid wood float with a grated float that maximizes light transmission; • Replace three treated wood piles securing the old float with two lO-inch galvanized pipe piles; • Replace two dolphins (consisting of three treated piles each), at the south end of the project site with a single 12-inch galvanized pipe pile at each location; • Avoid dredging along shoreline slopes and shallow water habitat along the shoreline north of the dredging zone to protect near-shore habitat that may be used by rearing Chinook salmon; 1 Currently federal permits are focused on the north end of the project site. 2 Spawning gravel sized substrate used to enhance nearshore aquatic habitat for salmonids. Lake Houses At Eagle Cove C:\Users\frys\AppData\local\ Temp\2016 La ke Study-l.docx Page 4 Lake Study Lloyd and Associates, Inc. • Enhance the north end of the project boundary through the placement of large woody debris (LWD) (approximately five to ten rootwads) to improve aquatic habitat, help stabilize the shoreline, and facilitate sediment deposition to reduce the need for future maintenance dredging; and • Conduct dredging only during the NMFS approved July 16 -September 15 work window. In Renton, shoreline areas are governed by the Shoreline Master Program and regulated specifically by RMC 4-3-090. Because Lake Washington is considered a critical area by the City of Renton, Renton Municipal Code (RMC) 4-3-0S0-F-2(c) requires that a lake study be conducted as part of any modification to a lake critical area. Specifically, the lake study must demonstrate that the proposed modifications would result in no net loss, meaning the applicant must demonstrate that the modifications, combined with any mitigation efforts, would result in equivalent or better protection of shoreline functions. This lake study fulfills the City's requirement. 2.0 EXISTING CONDITIONS AND ECOLOGICAL FUNCTIONS 2.1 DESCRIPTION OF THE STUDY AREA The proposed project area includes five waterfront lots in the Eagle Cove area of Lake Washington located immediately south of the May Creek Delta at 3905 -3909 Lake Washington Boulevard, Renton, WA 98056, including the boat house parcel (Figure 1). Appendix A shows the proposed expanded dredging zone. In order to encompass all indirect effects, such as increased turbidity during dredging, the study area includes the lower portion of May Creek and southern Lake Washington within approximately one half mile of the May Creek delta. It is anticipated that the one half mile project area is more than sufficient to encompass small and temporary increases in turbidity during dredging based on water quality monitoring during previous dredging in the delta. 2.2 CRITICAL AREAS AND HABITAT Lake Washington Lake Washington is the second largest natural lake in the state of Washington with 80 miles of shoreline, including about 30 miles along the shore of Mercer island. Lake Washington is a Shoreline of Statewide Significance and is classified as a Type-S waterbody. Over 82 percent of the Lake Washington shoreline is armored and is shaded by more than 2,700 piers and docks. Regulated lake levels and extensive armoring have hampered sediment transport and sandy beaches need to be augmented by periodic sediment supplies. Additional factors affecting the Lake Houses At Eagle Cove C:\Users\frys\AppData\Local\ Temp\2016 Lake Study-l.docx Page 5 Lake Study Lloyd and Associates, Inc. habitat features in the Lake Washington basin include a lack of riparian vegetation due to clearing and development; loss of channel and shoreline complexity including a lack of woody debris and pools; the development of fish passage barriers with the construction of road crossings, weirs, and dams; and degraded water and sediment quality caused by increases in pollutants and high temperatures. \.

Lake Houses At Eagle Cove C:\Users\frys\AppData\Loca I, Temp\2016 Lake Study-l.doc)( Page 6 Lake Study Lloyd and Associates, Inc. The Lake Washington/Lake Sammamish area includes two major rivers systems, the Cedar and Sammamish, and three large lakes (Lake Union, Lake Washington, and Lake Sammamish). It also includes numerous smaller streams such as Bear, North, and Swamp creeks that drain into the system from the north. Historically, Lake Washington had a vegetated shoreline of wetlands, trees, brush, and other mixed vegetation that created a diverse nearshore habitat for juvenile salmon ids and other aquatic species. Habitat degradation started with heavy logging of old growth forest throughout much of the watershed in the late 19th century. In 1901, the City of Seattle began diverting water out of the upper Cedar River to serve as its main water supply. Between 1910 through 1920, the natural Lake Washington outlet was redirected from the Black River to the Lake Washington Ship Canal and Hiram M. Chittenden Locks, which were excavated to connect Lake Washington to Lake Union and then to Puget Sound. Previously Lake Union was a freshwater lake that was not connected to Lake Washington and had no outlet to Puget Sound. The redirection of the Lake Washington outlet ultimately resulted in the lowering of the lake level by about 9 to 10 feet and the loss of over 10 miles of shoreline and approximately 1,000 acres of wetlands. Shallow lake margins and wetlands are generally considered to be high quality and preferred habitats for juvenile salmonids such as Chinook and coho salmon. During that same decade, the Cedar River was redirected from the Black River into the south end of Lake Washington. In the ensuing years, the most important cause of physical change to the watershed area has been the expansion of urban and suburban development. Despite the heavy alteration of the Lake Washington basin, it continues to support numerous salmonid stocks. The three watersheds in the basin with the largest salmonid populations, the Cedar River, and Bear and Issaquah creeks, support Chinook, sockeye, coho, steel head, rainbow and coastal cutthroat trout as well as native char (bull trout). Chinook salmon, steelhead trout, and bull trout are currently listed as Threatened under the Federal Endangered Species Act (ESA), and coho salmon are a Species of Concern under the ESA. Some of the small independent Puget Sound tributaries also support chum, coho, and cutthroat. Maps illustrating known and presumed distributions for each of these species are available in Kerwin (2001). Additionally, at least 40 non-native fish species (of which approximately 24 persist) have been introduced into the Lake Washington basin, most notably small mouth and largemouth bass, creating numerous trophic interactions with native species, including substantial predation on native salmonids. Sockeye salmon in the lake system are believed to be primarily the descendants of fry transplanted from Baker Lake in the 1930s. While many species have been introduced, native species such as Cedar River pink and chum salmon have been extirpated. Over the past 23 years3 numerous salmonid species have been documented at or near the proposed project site, including coho, Chinook, and sockeye salmon, rainbow trout/steel head, and cutthroat trout (Figure 4). No bull trout spawning activity or juvenile rearing has been 3 Lake surveys associated with permitting dredging and ather activities at the Barbee Mil site began in 1993. Lake Houses At Eagle Cove Page 7 C:\Users\frys\AppData\Local\ Temp\2016 La ke Study-l.dacx Lake Study Lloyd and Associates, Inc. observed in May Creek, and no distinct spawning populations are known to exist in Lake Washington outside of the upper Cedar River above Lake Chester Morse. Non-salmonid species documented during surveys in the study area included largemouth and small mouth bass, pumpkinseed sunfish, yellow perch, northern pikeminnow, three-spine stickleback, prickly sculpin, dace, and shiner (Harza 1993; Harza 2000; Meridian Environmental Inc. 2007; and Meridian Environmental Inc. 2012). These findings are consistent with the Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species (PHS) database list for the project site, which includes all of the above salmonid species, as well as bull trout. Figure 2. Coho salmon juveniles observed during the 2007 SCUBA survey. Adult Chinook typically migrate into Lake Washington at the Ballard Locks in mid-June, peaking in late-August (Kerwin 2001). Spawning typically occurs from mid-September through November. Juvenile Chinook rearing occurs from approximately January through June. Most juvenile Chinook move through the Ballard Locks by the end of June, although the entire outmigration period is unknown (Kerwin 2001). Adult coho begin entering Lake Washington in late-August and continue to enter the lake through early December. Most coho spawning occurs in November and December (Kerwin 2001). Juvenile coho typically rear for 12 to 14 months in freshwater. In Lake Washington, the peak of the outmigration occurs in early May (Kerwin 2001). Adult steelhead spawn from mid-December through early June in the Lake Washington basin. Juveniles can spend several years in freshwater before migrating to saltwater. Therefore, juvenile steelhead could be present in Lake Washington all year. Lake Houses At Eagle Cove C:\Users\frys\AppData\Loca 1\ Temp\2016 La ke Study-l.docx Page 8 Lake Study Lloyd and Associates, Inc. Adult sockeye salmon enter Lake Washington from late May to late August, and arrival peaks in early July (Hodgson and Quinn 2002). Adult sockeye hold in the lake below the thermocline all summer (Newell and Quinn 2005) and spawn in September-January. Juvenile sockeye rear for lor 2 years in the lake, although they are also found in the inlet and outlet streams of the lake. Six species of aquatic macrophytes have been documented in the project vicinity; elodea (E/odea canadensis), Eurasian milfoil (Myriophyllum spicatum), white-stemmed pondweed (Potamogeton pre/ongus), curly-leaf pondweed (P. crispus), American wild celery (Vallisneria americana), and common water nymph (Najos guoda/upensis) (Harza 1993; Harza 2000; Meridian Environmental, Inc. and Harza 2001). Elodea is a native species found throughout most of Lake Washington. Eurasian milfoil is a non-native species that first appeared in Lake Washington in the mid-1970s. According to Kerwin (2001), Eurasian milfoil has colonized a large percentage of the littoral zone and replaced much ofthe native aquatic vegetation present in littoral areas of Lake Washington. Curly-leaf pondweed, American wild celery, and common water nymph are also non-native to Lake Washington and are often found in ponds, lakes and sluggish streams to depths of 12 feet. In general, high densities of elodea, Eurasian milfoil, and curly-leaf pondweed have been observed in the nearshore portion of the proposed project area (at depths less than 12 feet) during the summer months (Harza 2000). The highest abundance is typically seen in depths of 6 to 9 feet, especially in areas with sandier substrates. Along the deeper water transects (greater than 12 feet), the distribution of aquatic macrophytes is patchier and less abundant. Very few if any macrophytes are found in depths greater than 15 feet (Harza 1993 and 2000). May Creek The mouth of May Creek is located on Lake Washington approximately 2 miles north of the Cedar River in Renton, Washington. The May Creek Basin drains an area approximately 14 square miles west of the Cascade Foothills between Issaquah Creek, Coal Creek, and the Cedar River. The headwaters of the basin include Cougar Mountain, Squak Mountain, and the East Renton Plateau. The main stem of May Creek contains approximately 7 river-miles of habitat and is fed by 13 primary tributaries. Historically, the May Creek watershed was forested with predominantly coniferous stands. Over recent decades, land uses in the western one-third of the basin have changed to intensive residential development. The eastern two-thirds of the watershed retains a mix of rural residential, small farms, and some forested areas (King County 2001). Developed communities in the watershed include Renton, Newcastle, and around Lake Boren, Honey Creek, and Lake Kathleen (Foster Wheeler 1998). The Urban Growth Boundary (UGB), established in accordance with the Washington State Growth Management Act (GMA), bisects the May Creek basin, which limits urban-scale development from encroaching on the headwaters of the basin. Land development in the lower basin has substantially reduced forest cover, increased impervious surfaces, and filled Lake Houses At Eagle Cove Page 9 c:\u sers\frys\AppData\Local\ Temp\2016 Lake Study" 1.docx Lake Study Lloyd and Associates, Inc. wetlands. Currently, the amount of effective impervious surface coverage basin-wide is approximately 7 percent. In addition, under current zoning, full build-out would result in approximately 12 percent of the May Creek basin being covered in impervious surfaces (King County 2001). This is significant, as basin-wide impervious surface areas of 10 percent or greater have been found to have considerable impacts on the health of aquatic ecosystems (May et al. 1997; Booth and Reinelt 1993; Karr 1991). Logging, coal mining, and agricultural activities have resulted in channelized streams, floodplain encroachment, and eroding slopes in the May Creek watershed. The lower 4 miles of May Creek are within an urbanized area. This portion of the creek experiences high sediment loading and lacks current and future sources of LWD (Foster Wheeler 1998). The lack of LWD has resulted in loss of habitat complexity, specifically pool habitat. Sediment deposition in lower May Creek has increased due to forest removal, the presence of rock quarries, and the expansion of road networks. Vegetation removal throughout the basin has resulted in higher maximum flows and lower minimum flows. The increase in flood flows has resulted in additional erosion of hillsides, flooding and sediment deposition in May Valley, erosion in the canyon downstream of the valley, and flooding and sediment deposition near the mouth of May Creek (King County 2001). Analysis of past, existing, and forecast storm runoff and flooding conditions of the May Creek Basin indicate that flooding will probably continue to increase as the basin is developed. As a result, the May Creek Basin Action Plan (King County 2001) includes several restoration goals, one of which is to protect and enhance fish and wildlife habitat and water quality in the basin. However, implementation of habitat restoration actions under the Basin Plan is dependent on funding availability. Historically, the Barbee Mill property (located adjacent to the May Creek delta) was highly modified, with mill operations dominating the land use (Figure 3). Approximately 85 percent of the site was covered by impervious surfaces in the form of pavement associated with mill operations and approximately 15 structures used for mill offices, log handling, sawing, milling, and storage of wood products. Over the past 15 years, and coinciding with the construction of the Barbee Mill housing development, the Barbee Mill Company has substantially improved the vegetated cover in the May Creek riparian area from its confluence with Lake Washington to Lake Washington Boulevard by planting willows, cottonwoods, grasses, and other native vegetation (Figure 4). In this area, the vegetated stream buffer ranges from approximately 5 to over 100 feet in width. In addition, the Barbee Mill Company has placed clean fish rock over 2,100 square feet of the shoreline along the lake's rockery shoreline to the south of the boathouse dock to enhance shallow water habitat for fish.

According to Foster Wheeler (1998), the lower reaches of May Creek experience the heaviest use by fish. However, the primary limiting factor for Chinook and sockeye in May Creek likely is available spawning area and incubation success. The primary limiting factor for coho, steelhead, and cutthroat in May Creek likely is the availability of high quality rearing and over- wintering habitat (Foster Wheeler 1998). Wetlands According to King County's iMap database' there are no wetlands located within the immediate vicinity of the proposed expanded dredging site. Nor do any other publicly available data indicate the presence of aquatic areas aside from Lake Washington and May Creek. Habitat As discussed above, the littoral zone and shoreline of Lake Washington have been extenSively modified in the past 150 years due to the change in lake level; construction of piers, docks, and bulkheads; removal of LWD; and the expansion of Eurasian milfoil and other non-native aquatic macrophytes (Fresh and Lucchetti 2000). The previously hardstem bulrush-and willow- dominated shoreline community has been replaced by developed and hardened shorelines with landscaped yards. According to Toft (2001), an estimated 71 percent of the Lake Washington shoreline is armored with riprap or bulkheads and approximately 2,737 residential piers have been built. This loss of natural shoreline has reduced the occurrence of complex shoreline habitat features such as overhanging and emergent vegetation, woody debris (especially fallen trees with branches and/or rootwads intact), and gravel/cobble beaches, which has reduced the availability of refuge habitat and forage for juvenile salmonids. like most of the shoreline along Lake Washington, the shoreline in the proposed project area is armored with riprap; however, emergent vegetation (50ft rush, grasses, sedges, etc.) grows at depths less than 3 feet in areas to the north and east of the proposed dredge site. In 2007, juvenile rainbow trout, coho salmon, and sticklebacks were observed using this emergent vegetation as cover. Soils/Substrates Sediments in the proposed expanded dredge area (arising from May Creek depositional events) tend to be fine to medium sands (SP -MP) grading to gravels in closer proximity to May Creek. Sediments distal to May Creek trend to finer materials and silt. Within the May Creek delta, larger cobbles and gravels are the dominant substrates. Riprap, cobble, sand and gravel generally occur at depths less than 3 feet to the north and east of the proposed dredging zone. According to the Natural Resources Conservation Service, the property (upslope of the ordinary high water mark (OHWM) contains Alderwood gravelly sandy loam (Age) soil; however, this area would not be disturbed by the project. 4 http://www . k i ngco u n tv .g ov I se rvi ces/gis/M aps/i ma p.a spx Lake Houses At Eagle Cove C:\Users\frys\AppData\Loca 1\ Temp\2016 Lake Study-l.doc)( Page 12 Lake Study Lloyd and Associates, Inc. Wildlife In addition to the fish species described above, the WDFW PHS database lists three bald eagle nests within 1 mile of the project site. All three nests are located to the west of the May Creek delta on the southeastern tip of Mercer Island. It is reasonable to assume that bald eagles may fly over the project site and that they may forage in the project area based on the presence of documented nest sites and potential forage species, such as waterfowl, seagulls, and salmon, which occur in and around May Creek and the southern portion of Lake Washington. There is an existing osprey nest platform at the mouth of May Creek that has been occupied during the breeding season (March through September) in the past, but no nest was seen on the structure in December 2016. In addition to osprey, Meridian biologists have observed a variety of ducks, Canada geese, and turtles during fish habitat and fish population surveys in the project area. 2.3 2016 AQUATIC HABITAT SURVEY On December 16, 2016, Meridian Environmental fisheries biologists completed detailed SCUBA- based aquatic habitat and fish presence surveys at the project site. Areas surveyed were (1) within the proposed expanded dredging zone to the inner harbor line; and (2) along the eastern and northern shoreline adjacent to the proposed dredging area; and (3) around the boat house. The objective of these surveys was to: • Document the existing aquatic habitat conditions during the winter of 2016; • Determine the species composition and average densities of aquatic macrophytes; and • Describe the distribution and relative abundance of fish species observed during the survey. An additional objective was to compare the results of 2016 surveys with the results of fish habitat and fish population surveys completed within and near the project area in 1993, 2000, 2001,2007, and 2012). Survey Methods A Meridian fisheries biologist established seven underwater transects between the south end of the May Creek delta and the existing dock and log boom located at the south end of the proposed project area (Figure 5). Transects were designed to cover a large portion of the proposed expanded dredge prism, ranged from 100 to 225 feet in length, and extended approximately 500 feet into Lake Washington. Similar to previous surveys, two fisheries biologists then used SCUBA equipment to swim each of the seven transects approximately 2-3 feet above the surface of the lake bed. While swimming each transect, divers recorded the water depth, dominant substrate, the species and Lake Houses At Eagle Cove C:\Users\frys\AppData\Loca 1\ Temp\2016 lake Study-l.docx Page 13 Lake St udy Ll oyd and Assoc iates, Inc. size class of any fish encountered, aqu at ic macroph y t e composition and de nsity, and underwa ter visibility. Aquatic macrophyte densities were visually esti m at ed and classif ied as lo w (le ss than or equal to 10 stems p er squ are yar d), moderate (11 to 100 st em s per square yard). or h igh (greater than 100 stems per squ are yard).

Low densities of M. spicatum and E. canadensis. 7 Proceeded along shoreline from the boat ramp to the base of the dock at None south end of proposed dredge prism (Figure 5). Substrate was comprised of mostly gravel, cobble, and leaf litter. Depths average 2-3' and aquatic vegetation was sparse. Abundant small freshwater mussels (Figure 12). As in past SCUBA/snorkel surveys, the substrate in the proposed project area was observed to be a mixture of silt and sand, riprap cobble, leaf litter, and fish rock patches. Riprap cobble, sand, and gravel were the dominant substrates observed along transect 7 (Figure 5). The riprap cobble and gravel was typically located within 6 feet of the shoreline to a depth of approximately 3 feet. Sand was the dominant substrate along Transect 1 and silt and organic debris (e.g., leaf material) were the dominant substrates along the remaining transects.

As discussed in Section 2.2, six species of aquatic macrophytes have been documented within and near the proposed expanded dredging area during past SCUBA/snorkel surveys. In general, high densities of E. canadensis, M. spicatum, and P. crispus have been observed in the nearshore portion (depths less than 12 feet) during the summer months (Harza 2000, Meridian Environmental, Inc. 2007; Meridian Environmental, Inc. 2012). The highest abundance is typically seen in depths of 6 to 9 feet, especially in areas with sandier substrates. Along the Lak e Ho uses At Eagle Cov e Page18 C:\Us er s \f rys \AppData\local\ T e rnp\2016 La ke St udy-l ,duo Lake Study Lloyd and Associates, Inc. deeper water transects (greater than 12 feet). the distribution of aquatic macrophytes is patchier and less abundant. Very few if any macrophytes are found in depths greater than 15 feet. In 2016, biologists observed low, moderate, and high densities of E. canadensis, M. spicatum, and P. crispus in the project vicinity, depending on the transect. Densities were highest along transects 3 and 4 at depths less than 12 feet (Figure 4) and lowest along transects 1, 2, 3, and 7. 3.0 PROJECT DESCRIPTION 3.1 PROJECT PURPOSE For decades, the Barbee Mill site (owned by the Cugini family) and May Creek delta have been affected by ongoing development in the upper May Creek valley. Upstream development has resulted in higher peak flood flows due to increased impervious surface in the watershed. Peak flows have increased approximately 15 to 20 percent compared to pre development conditions for the 2-, 25-, and 100-year flood event return intervals (King County 2001). In addition, this increased run-off has resulted in severe bank erosion and sediment transport from the upper basin, which is deposited in the May Creek delta adjacent to the Barbee Mill. Subsequently, wave action in Lake Washington transports fine sediment from the delta to the boathouse area, which is located to the south of the May Creek delta. Dredging of the May Creek delta and Cugini property boathouse area has occurred for over 50 years on a 3-to 4-year cycle, depending on the volume of sediment accumulation. The amount of sediment deposition has been described as increasing from 3,000 to 4,000 CY every 3 to 4 years throughout the 1990s to 4,000 to 6,000 CY per in the 2000s. 3.2 PROPOSED SHORELINE MODIFICATIONS The proposed project would involve amending the current Corps programmatic permit to allow dredging of up to an additional 4,000 cubic yards of sediment in an area located adjacent to the existing permitted dredge prism (Appendix A). Dredging to achieve the desired navigational depth profile would deepen the expanded dredge prism by approximately 10 feet (Appendix A). This expansion of the dredge prism would align it with the existing property and inner harbor lines, facilitate safe navigational access to the boathouse, and promote future recreational uses. The current permit reference is NWS-2007-1019-NO. There would be no change in the frequency of dredging events. Dredging events would continue to occur in both the existing and expanded dredge prisms every 3 to 5 years, based on periodic evaluation of sediment depth. Lake Houses At Eagle Cove C:\Users\frys\AppData\Local\ Temp\2016 Lake Study-Ldocx Page 19 Lake Study Lloyd and Associates, Inc. There would be no change in the duration or timing of dredging events. As in the past, work would be accomplished within a 3-to 5-day period, and would be scheduled to occur within the in-water work window specified by the National Marine Fisheries Service (NMFS). The NMFS in- water work period, which is designed to limit impacts to aquatic species, is July 16th to September 15 th • As is currently permitted, accumulated sediments would be removed with a small dredge and clamshell bucket. Portions of the work may also be conducted with a long-reach excavator from the land or an excavator mounted on a fenced flat barge. Use of any other type of dredge would require prior approval from the Corps and Washington Department of Ecology (Ecology). Sediments would be loaded on a barge, transported, and off-loaded at an approved fill material stockpile zone for beneficial upland uses. 4.0 ANALYSIS OF ALTERNATIVES An alternative location for the project is not feasible, as the project is intended to ensure continued safe navigational access to the boathouse and promote future recreational uses. However, pursuant to RMC 4-9-050-L(I)(b), measures to avoid, minimize, and rectify impacts to the on-site shoreline critical area have been incorporated into the dredging plan. Minimization techniques include lining the perimeter of the barge with hay bales wrapped with filter fabric to prevent dredge material from entering Lake Washington, where it could cause turbidity. Conducting dredging only during the NMFS approved July 16 -September 15 work window would also minimize the risk of turbidity, by avoiding work during the rainy season. To protect and enhance aquatic habitat in the project vicinity, the project proponent is also proposing to: • Place 20 CY fish rock along the rockery as well as several yards of fish rock adjacent to the boat ramp on Lot A; • Demolish the existing solid-surface 38-foot float and replace it with a grated float that is 24 feet long. Replace three treated wood piles securing the old float with two lO-inch galvanized pipe piles; • Replace two dolphins (consisting of three treated piles each), at the south end of the project site with a single 12-inch galvanized pipe pile at each location; • Avoid dredging along shoreline slopes and shallow water habitat along the shoreline north of the dredging zone to protect near-shore habitat that may be used by rearing Chinook salmon; and Lake Houses At Eagle Cove C:\Users\frys\AppData\Loca 1\ Temp\2016 La ke Study-l.docx Page 20 Lake Study Lloyd and Associates, Inc. • Enhance the north end of the project boundary through the placement of LWD (approximately five to ten rootwads) to improve aquatic habitat, help stabilize the shoreline, and facilitate sediment deposition to reduce the need for future maintenance dredging. 5.0 IMPACT EVALUATION The proposed mitigation measures described above were designed using best available science, in accordance with RMC 4-8-120-19, and RMC 4-3-050-L-1-c, to avoid and minimize potential project impacts on aquatic habitat and salmonids and provide adequate mitigation. A discussion of project effects, including the effects of mitigation, is presented below. 5.1 HABITAT The proposed project is unlikely to have an adverse effect on adult salmon and steelhead spawning habitat, as no dredging would take place in May Creek. The proposed in-water work window (July 16th to September 15 th ) and relatively short dredging period (3 to 5 days of work) would also limit the potential to delay migration or spawning in May Creek. The proposed project may affect juvenile salmon and steel head by causing physical changes to their early rearing habitat in Lake Washington. However, according to Tabor et al. (2006), Chinook fry begin entering Lake Washington around the first of the year, peaking in February, while parr and smolts enter the lake from April through July, peaking in late May. Past studies of juvenile Chinook salmon distribution and abundance in Lake Washington indicate that they are concentrated in the south end of Lake Washington from February to May; however, their density along the shorelines in the spring decreases logarithmically with increasing distance from the mouth of the Cedar River (Tabor et al. 2006). These studies also found that juvenile Chinook salmon prefer shallow water habitats with overhanging vegetation, with an approximately 4.5:1 ratio of fish using overhanging vegetation to fish occurring away from overhanging vegetation (Tabor et al. 2004, 2006). While data describing juvenile steel head and coho use of Lake Washington are limited, both Tabor et al. (2004) and Meridian Environmental, Inc. (2007) have documented the presence of juvenile steelhead and coho in the proposed project area. Like juvenile Chinook, both of these species appeared to prefer the shallow water habitat located along the shoreline to the north and northeast of the proposed expanded dredging area, and were typically associated with overhanging brush and emergent vegetation. Juvenile coho were also abundant in the shallow water areas (less than 3 feet deep) located along the northeastern corner of the boathouse dock. No steelhead or coho were observed at depths greater than approximately 3 feet. Lake Houses At Eagle Cove C:\Users\frys\AppData\Local\ Temp\2016 Lake Study-l.docx Page 21 Lake Study Lloyd and Assoc.iates, Inc. Based on the results of previous studies completed in the project area, water depths in the proposed expanded dredging zone are generally deeper than those preferred by rearing juvenile Chinook, coho and steel head. In addition, the aquatic habitat located immediately to the south of the May Creek delta and along the shoreline of the lake to the south is not heavily used by juveniles of these species (Tabor et al. 2004). Limiting in-water work to the NMFS approved work window would minimize the potential to adversely affect juvenile Chinook, as the vast majority of juveniles in Lake Washington are expected to migrate prior to July. This in- work window would also minimize potential impacts on juvenile coho and steelhead. While the proposed project may cause a short-term negligible increase in turbidity/suspended sediment (see below) and a reduction in benthic invertebrates in the dredging zone, overall long-term water quality would be improved by removal of the toxic creosote pilings. Primary productivity and the fish forage base would be improved as a result of increased light penetration into the lake, and shoreline and instream habitat quality would be improved through the addition of fish rock. 5.2 LARGE WOODY DEBRIS LWD (logs with attached rootwads) is an important component of a healthy stream ecosystem. Large trees that fall into streams perform an important role in forming pools, regulating storage and routing of sediment, and trapping spawning gravel. LWD also provides complex fish habitat that increases carrying capacity, high-flow refugia for fish, and substrate for macroinvertebrates. The delivery and routing of LWD in May Creek has been altered by past timber harvest and urban and rural development and its role in forming habitats (especially pool habitat) is very limited. The placement of approximately five to ten anchored rootwads along the north end of the project boundary, as a component of the proposed project, would likely improve aquatic habitat salmonids, help stabilize the shoreline, and may facilitate sediment deposition to reduce the need for future maintenance dredging south of the delta. These large pieces of LWD are also expected to provide relatively stable habitat elements and trap pieces of naturally recruiting wood to form increasingly complex log jams that would be retained during periods of high flow. As a result we expect the LWD structures to slightly increase resident and anadromous fish productivity in lower May Creek. 5.3 OVERWATER COVER Juvenile Chinook salmon tend to avoid overwater structure. Tabor et al. (2006) found that upon approaching a pier, juvenile Chinook will move into deeper water and either pass under or swim around the pier. Similarly, in acoustic tracking studies, Chinook smolts avoided areas under overwater structures and changed course to move around such structures (Celedonia et al. 2008). The change in light levels associated with piers and other overwater structures may Lake Houses At Eagle Cove C:\Users\frys\AppData\locai\ Temp\2016 Lake Study-l.docx Page 22 Lake Study Lloyd and Associates, Inc. make it difficult for juvenile Chinook salmon to detect predators (Tabor et al. 2006), and salmon predators like smallmouth bass are often associated with pier piles (Celedonia et al. 2008). The project proponent would remove a solid-decked float in the project area and replace it with a new fully grated float to maximize natural light transmission. The new grated float would likely improve primary productivity and the fish forage base by allowing greater natural light penetration to the lakebed. Grating specifications would comply with previously approved permit conditions for light transmission. The project proponent would also remove two dolphins (consisting of three treated piles each) at the south end of the project site and replace those with a single, much smaller 12-inch galvanized pipe pile at each location to reduce the amount of structure that would attract predatory fish. Overall, these measures are expected to improve juvenile salmon habitat conditions and reduce predation in the project area. 5.4 LIGHTING Artificial nighttime lighting has been shown to affect the behavior of various aquatic organisms, including many salmonids. Light-mediated behaviors may include changes in foraging, predator avoidance, reproduction, and migration. Often fish are attracted to artificial nighttime lighting (positive phototaxis) and their behavior may more resemble daytime behavior than nighttime behavior, which can potentially make them more vulnerable to predation (Tabor et al. 2015). No artificial lighting is proposed as part of the expanded dredging project. 5.5 WATER QUALITY (SUBSTRATE DISTURBANCE AND DISCHARGE OF WASTE PRODUCTS) Dredging has the potential to increase turbidity (i.e., reduce water clarity) and increase total suspended solids (TSS) within and near the proposed action area. Turbidity and TSS levels have been reported to cause physiological stress, reduce growth, and adversely affect salmonid survival. The potential for adverse effects depends upon several factors, including the duration of TSS increases, the area of the turbidity plume, the amount and velocity of ambient water (dilution factor), and the size of suspended sediments. In the case of the proposed project, increases in suspended sediments and turbidity would be localized at the point of dredging and increases would last for only short periods of time; based on previous dredging activities, these periods are expected to be less than several hours. Evidence suggests that salmonids are well adapted to short term increases in turbidity, as such conditions are frequently experienced in natural settings as a result of storms, landslides, or other natural phenomena (Redding et al. 1987; NMFS 2003). It is chronic exposure to increased turbidity that has been found to be the most potentially damaging to salmonids. Studies have found that when habitat space is not limiting, salmonids will move to avoid localized areas of increased turbidity, thereby alleviating the potential for adverse physiological impacts (Bisson and Bilby 1982; NMFS 2003). Lake Houses At Eagle Cove C:\Users\frys\AppData\Local\ T emp\2016 Lake Study-l.docx Page 23 Lake Study Lloyd and Associates, Inc. Juvenile salmon have been shown to avoid areas of unacceptably high turbidity (Servizi and Martens 1991), although they may seek out areas of moderate turbidity (10 to 80 NTU), presumably as cover against predation (Cyrus and Blaber 1987a, 1987b). Studies have found that fish that inhabit waters with elevated TSS may experience a reduction in predation from piscivorous fish and birds (Gregory and Levings 1998). In such cases, salmonids may actually increase foraging activity, as they use turbid water as a sort of cover from predators (Gregory 1993). However, feeding efficiency of juveniles is impaired by turbidities in excess of 70 NTU, well below sublethal stress levels (Bisson and Bilby 1982). Reduced preference by adult salmon returning to spawn has been demonstrated where turbidities exceed 30 NTU (20 mg/L suspended sediments); however, Chinook salmon exposed to 650 mg/L of suspended volcanic ash were still able to find their natal streams (Whitman et al. 1982). The highest turbidity values recorded during dredging activity at the site in 2002 were less than 7 NTU, and turbidity measured in the dredging zone was on average less than 1.4 NTU greater than turbidity outside the dredging zone. Overall turbidity values of less than 7 NTU are very low, and the effect of slightly increasing turbidity by 1 or 2 NTU on listed fish species should be considered discountable. Based on these data and the scientific literature cited above, it is unlikely that the short-term (3 to 5 days every 3 to 5 years) and localized elevation of turbidity (less than 5 NTU elevation above background turbidity levels) generated by the proposed project would rise to the levels that would be expected to cause harm to salmonids that may be present in the dredging zone. While some return water from dredged materials placed on a barge is anticipated to enter Lake Washington, it is extremely import to understand that the dredged material is highly porous and drains very quickly during dredging as the bucket is raised out of the water. This return water is the subject of the Water Quality Certification approved by Ecology. Notably, there is very little silt or clay content in dredged materials as indicated in recent sediment testing. Essentially, the sediments are virtually dryas loaded onto the barge. The perimeter of the barge will be lined with hay bales wrapped with filter fabric to further reduce the potential for introduction of sediments into Lake Washington. Considering that the turbidity produced by any construction activity would be localized and temporary, the most probable impact on juvenile salmon ids would be a behavior modification (avoidance response), rather than injury or reduction in growth potential. An avoidance response could expose juvenile salmonids to increased predation or force them away from preferred rearing areas. The project proponent would employ the most effective strategy for minimizing or eliminating potential construction related impacts, which is to restrict construction to periods when the presence of Chinook and coho salmon, steel head, and bull trout is improbable. In-water work such as dredging also has the potential to degrade water quality though the spill of toxic substances, such as fuel or hydraulic fluid from dredging or pile placement equipment. This potential is best reduced by maintaining equipment in proper working condition and by maintaining a spill prevention control and countermeasure plan (SPCCP). Typically, a SPCCP Lake Houses At Eagle Cove Page 24 C:\Users\frys\App Data\local\ Temp\2016 lake Study-l.docx Lake Study Lloyd and Associates, Inc. would specify areas for equipment maintenance and refueling, spill prevention and emergency response strategies, requirements for keeping emergency response spill containment kits onsite, and for having trained personnel be onsite during in-water work. For this project, preparation of a SPCCP would limit the potential for toxic material spills during dredging and pile replacement. If oil or other unknown substances appear on the water surface or in dredged material while equipment is being operated, the contractor will cease operations immediately to identify the source of the contaminant and remedy the problem. If necessary, an oil absorbent boom secured to a debris boom will be utilized to encircle the work zone to capture sheen or potential floating debris. Finally, replacing the three creosote treated wood piles and two dolphins in the project area with galvanized pipe piles is expected to provide an overall increase in water quality, as slow solution of some creosote components and physical breakdown of the treated wood leads to toxicity in the surrounding water and sediment .. These piles would be pulled concurrent with the May Creek enhancement work. All creosote treated pilings would be cut into 4-foot lengths and disposed of in an approved upland landfill. 6.0 CONCLUSION Periodic maintenance dredging every 3-5 years in the proposed expanded dredge prism coupled with the protection and enhancement measures outlined in Section 4.0 are expected to preserve navigational access to the project proponent's docks and boathouse; maintain and possibly improve water quality conditions in the project area; enhance aquatic habitat and hydraulic functions in lower May Creek; slightly increase primary productivity and near-shore habitat quality in lake Washington; and reduce predation in the project area. Overall, no net loss of shoreline ecological functions will result from the proposed project.

The purposes of this sampling and analysis program are: (I) to chemical collect data regarding the level(s) of contamination that mayor may not be present within sediments of the permitted dredge area; and (2) to assess the suitability of dredged materials for open-water disposal. The purpose of the proposed dredging is to maintain navigational and recreational access. As currently permitted, we anticipate approximately 2500 to 2700 CY of material will be dredged in 2017 based on 2016 hydrographic data. Site History -Historical Dredging The project area (see Figure 1-1) has been dredged for many decades. In recent history, the area was dredged in 1994, 1997,2001/2002 and 2011. The boathouse was constructed in the 1950's, and has been in continuous use. A portion of the Barbee Boathouse Navigational Dredge area was last dredged in 20 II, concurrent with boathouse renovation under USACE Permit Reference #NWS-2007-1 0 19.

Quendall Terminals is a CERCLA (superfund) site managed by EPA. Primary contaminants at this site are creosote residues (PAH compounds) and petroleum hydrocarbons. Barbee Lumber Mill operations occurred north of the May Creek Delta, and south of Quendall Terminals. Lumber mill operations were essentially shut down in 1999. The boathouse area has been periodically dredged since the early 1950' s to maintain navigational access to the boathouse. There is no record of spills or other discharges impacting sediments in the proposed dredge area although low levels of petroleum hydrocarbons were detected during sampling and chemical analysis in 2008. Sediments in the proposed dredge area arise principally from deposition during severe storm events (high energy) when sediment loadings carried from the May Valley Drainage Basin are substantial. Sediments to be dredged in the future are derived from depositional events that have occurred at the May Creek Delta for many years. The project proponents seek to dredge depositional sediments that have infilled the navigational access to the boathouse. The Barbee Company has secured all permits to dredge the area from the USACE and is currently updating permits from state and local jurisdictions. As permitted by USACE, our proposal is to dredge the permitted profile approved by USACE. This profile will not reach depths that will encounter sediments that are older than dredging work completed in 20 II or in previous dredging events. In all respects we will not be dredging to depths that at or below 10-12' elevation (MSL, Corps Datum). In 2002 the depth at the western edge of the dredge footprint was approximately 15-20 feet deep, well below proposed dredge profile. In 2005. for example. the water depth at the Eagle Roost (also periodically referred to the Osprey Nest) was approximately 10' (12' EI. MSL). Since 2005. there has been over 10' of depositional infill from on going erosional events. While the numbers are not well developed, the volume of material deposited in Lake Washington at the May Creek Delta is at least 25,000 CY (and likely substantially higher). The point is that the project proponents are not dredging older lakebed sediments by any means. We are simply looking at dredging the least amount of depositional material possible to maintain access to the boathouse. boat ramp. and shoreline access for protected recreational uses. The proposed depth profile for dredging will occur within recent infill/deposition. These results are also to be considered a supplement to previous sediment sampling and analysis work conducted in 2007 (reported in 2008) and years prior (see Attachment D -Historical Summary Data Summary). Sediment Sampling Results -Summary Detected chemical contamination in the permitted dredge area (DMMU-I) is very limited. Testing results are below DMMP fresh water and marine screening levels for all parameters (see Section 3.0 Chemical and Physical Data). Nevertheless, some motor oil range petroleum hydrocarbon was detected at 39 mg/kg (dry basis). Diesel Lloyd & !\~~OCi<lll's. Illc. Page 5 onu range petroleum product was detected in the composite sample at 8.3 mg/kg (dry basis). Additionally, traces of Polynuclear Aromatic Hydrocarbons (PABs) were detected. For example, benzo(a)pyrene was detected at24 ug/Kg (dry basis). Suitability of Dredged Material for Open Water Disposal All data indicate that detected chemical contamination levels are below all low-level screening criteria, and that the materials are acceptable for disposal at a DMMP open- water disposal site.

Sediment samples were collected, composited and preserved for next day delivery to Analytical Resources, Inc. (Seattle, W A). This section provides a summary of sediment sampling information. Sediment Sampling Logs are provided in Attachment A. Sample Stations Differential GPS was utilized to locate sediment sample stations. Sampling occurred close to proposed locations as moderated by observed field and gusty weather conditions. Sampling locations are summarized in Table 2-1 below. All data was collected using North America Datum (NAD83-Washington North). Lake Elevation at the time of sampling was provided by the USACE at Chittenden Locks. Lake elevation was 20.6 feet (MSL), approximately 1.2 feet below the Ordinary High Water Line (OHWL).

Sample recoveries were generally very good fro Sample SED-2(> 70%) as shown in Sediment Sampling Logs provided in Attachment A. However, recovery at SED-I was poor due to nature of materials sampled. The middle section of the drive met little resistance, and it is believed that we hit a homogeneous loose sandy layer that was lost with extraction of the gravity corer. A repeat drive was conducted with the same results. At no time did it appear that we hit a hard substrate such as might be anticipated in a lake bottom. Because of the consistency of core results (mostly fine to medium sand) all sediments appear to Lln~d &.

SED-3, was collected with a small vanVeeen sampler with 100% recovery. Sediment Sampling Stations are shown in Figure 2-1. / L Figure 2-1: Sediment Sampling Stations (I'rol""eu and Actual) Field Sampling Procedure Because of the recent substantial deposition (arising from May Creek), sampling was accomplished by walking out to the sampling locations with the exception of the boathouse sample (SEO-3) which was collected just outside the boathouse from an adjacent float. Depth to mudline (something of a misnomer, since no mud was encountered) was measured with a weighted line. The 8' gravity corer included a 24" extension with an added drive weight. The sampler was generally easily extracted and raised out of the water. The only problem encountered with sampling recovery occurred at SEO-I where we hit a pocket of low resistance, believed to be homogeneous sandy materials. Sediment cores at SEO-l and SEO-2 had low water content when extracted. Once extracted from the lined sampler, the sample core was visually inspected and logged. Core contents from within the dredge profile were retained in individual stainless steel bowls. Mixing of the core contents was with a clean stainless steel spoon. No attempt was made to select layers or otherwise alter the sample contents. Equipment Decontamination Prior to sampling, all sampling equipment was decontaminated by scrubbing with a dilute solution of Alconox, rinsed with tap water, and then followed by two rinses of distilled water. In the field, the samplers were rinsed with lake water and visually inspected prior to moving to the next sampling station. A solvent rinse was not utilized at any time. Composite Preparation l.Io)J & ASSOCIates, Inc Page 8 of 30 2u I (,-213 SedlllKllt S:.lll1rlll1g He-;ulh I)M'vll -I A composite sample was constructed from SED-I, SED-2 and SED-3 sediments. The composite was weighted 45% each of SED-I and SED-2. and 10% of SED-3. It is unlikely that dredging will occur at the boathouse (SED-3) in the near future because recent sediment deposition patterns to the west predominate, and there is currently adequate navigational depth. A pre-cleaned stainless steel bowl and spoon was utilized to composite samples. Portions were well mixed to a homogenous consistency. The composite sample was identified as 070420l6/SED-C. Chain-of Custody The laboratory provided chain of custody was utilized to record basic sample infonnation and requested analyses. All samples were labeled, bagged in Ziploc bags, chilled with ice, and delivered to the laboratory the next day under chain of custody. A copy of the Chain of Custody is provided in Attachment C. Grain Size Distribution Logs I Field Observations Sediment Sampling Logs are provided in Attachment A. In general. sediment sampling yielded good recoveries because of the cohesive nature of the sediment in the sampling profile. However, recoveries at SED-1 were marginal as the lower portions of the core were lost during sampler extraction. Grain Size Data is provided in Table 2-2 and graphically presented in Figure 2-2. These sands appear to be relatively recent origin and do not suggest that sediments below the proposed dredge profile were encountered. Sediments from SED-l and SED-2 were odor free and no apparent sheen was observed in any grab sample although a light stringy sheen was observed in SED-3. A transient "rotten" smell was also noticed in SED-3 The upper few inches of each core was layered with coarse sand and pebbles with the exception of SED-3 which had twigs, leaf litter, and milfoil stringers. Milfoil distribution was extensive throughout shallow waters. However, in those areas of recent sediment deposition, the surface was bare of vegetative growth as observed at SED-l and SED- 2 Sampling Stations. All samples, as collected. were sandy and gritty to the touch.

Standard Reference recoveries were acceptable and met the Advisory Range for all metals. Method blank results were at or below reporting/detection limits. All metals data presented in Table 3-2 are acceptable as qualified by the laboratory. Semivolatile Organic Compounds Composite Sample 07042016/Barbee/C was analyzed for semivolatile organics by EPA GCMS Method 8270D, following PSDDA protocols. Sample reports and QC reports are provided in Attachment C. Duplicate precision data was acceptable with RPDs less than 20% for all parameters. Matrix spike and matrix spike recovery data were acceptable, as well acceptably reproducible. Surrogate recoveries met EPA method recovery limits/action criteria. Surrogate recovers were with QC warning limits. Initial instrument calibration for bis(2-Ethylhexyl)phthalate was out of control and appropriately qualified, as Q. Standard Reference (SRM-070716) recoveries were acceptable and met laboratory acceptance criteria. Method blank results were at or below reporting/detection limits. All semivolatile organic data reported in Table 3-4 is deemed acceptable as qualified. Pesticides and PCBs Composite Sample 07042016/Barbee-C was analyzed for pesticides and PCBs by GC/ECD (Dual Column -Methods 8081A and Method 8082, respectively) following PSDDA protocols. As shown in Table 3-5 no pesticides or PCBs were detected at reporting limits. All reporting limits for all pesticides and PCB's were not detected and less than Screening Levels for both Marine and Fresh Water. Additionally. all undetected levels were less than MTCA Method A -Soil Cleanup Levels for Unrestricted Land Use. A detailed quality assurance summary of pesticide and PCB data, respectively is provided in Attachment 3. Surrogate recoveries were acceptable and duplicate precision data was acceptable with RPDs less than 17% for all pesticide parameters and less that 6% for PCB's. Matrix spike recovery data was greater than 50%. Spike recoveries were greater than zero for all parameters and within acceptance criteria. Surrogate recoveries met EPA method recovery limits/action criteria for all surrogates. Standard Reference recoveries for Laboratory Controls for pesticides and PCBs (SRM PSR) were acceptable and met laboratory acceptance criteria.

LIm d & A:-.socmle's. irK Page ~I of30 Petroleum Hydrocarbons Composite Sample 070420 16/Barbee-C was analyzed for petroleum hydrocarbons by GC/FID (Method NWTHH-D). Results are provided in Table 3-6. Surrogate recoveries met EPA method recovery limits/action criteria for all surrogates Standard Reference recoveries were acceptable and met laboratory acceptance criteria. Method blank results were at or below reporting/detection limits. Spike recoveries gave acceptable precision, and spike duplicate analyses indicated acceptable accuracy. All data reported in Table 3-6 for petroleum hydrocarbons is acceptable as reported. Dioxins and Furans Analysis was performed using the application specific RTX-Dioxin 2 column, which has a unique isomer separation for the 2378-TCDF, eliminating the need for second column confirmation. Initial calibration and continuing calibration verifications were within method requirements. However, the initial calibration verification fell outside the control limits low for 13CI2-2,3, 7,8-TCDF, 13CI2-1 ,2,3,4, 7,8-HxCDF, and 13CI2-1.2,3,6,7,8-HxCDF. All other compounds were within control limits. Both extraction and cleanup surrogates had recoveries within control limits, and the method blank contained reportable responses for several compounds. "B" qualifiers were applied to associated results that were less than ten times the levels found in the method blank. The laboratory control sample gave percent recoveries were within control limits. The PSR SRM (SRM-072116) was analyzed as a reference material. Specific results have been flagged "EMPC", indicating a response not meeting all requirements of positive identification. The EM PC values were treated as undetects. l.loyd & i\:';soclales. Inc Page 22 of 30 ~(J16-213 Sedllllell\ ~JlTlllliTlg l'k~lIll~ 1)\11\'11 -I 5.0 Conclusions and Recommendations Sediment Sampling Sampling work conducted at the Barbee Navigational -Maintenance Dredging area was informative. Prior to sampling we had anticipated that medium to course sandy materials would be encountered based on previous experience. Portions of the proposed dredge area outside of the boathouse were most recently dredged in 20 II and previously in 2002. Depositional infill sediments, currently within the proposed dredge profile, tend to be finer sediments unsuitable for shallow water fish habitat enhancement along the rockery to the immediate south. Therefore, all dredged materials will be disposed in open water. Core sampling in sandy sediments was marginal at best at SED-J where recoveries were low at 37.5% Nevertheless, we arrived on site with a number of sampling devices. The gravity corer worked out reasonable well, and the vanVeen sampler worked great for the shallow sample near the boathouse. However, given the poor recoveries at SED-I, a better choice for sample collection might be a vibrocore sampler where a longer continuous core is desirable. Nevertheless, vibrocore samplers have similar limitations in dealing with fine sands, as were encountered at the project site. Based on our experience in sampling conditions encountered, it is not clear that a vibrocore sampler would have worked out better. Because actual proposed dredging depths are relatively shallow and generally less than 10 feet, additional sampling data seems unnecessary although a Z sample could be collected for conformational analyses. At no time will dredging reach former lake bed elevations as dredged in 2002 or 20 II. In major part the growth of the May Creek Delta severely limits the steepness of slopes that can be sustained within the project area. There are also financial considerations. The project proponent is not interested dredging to the maximum that may be possible. The purpose is to maintain navigational access, not see how much money can be spent to restore historical lakebed elevations in Lake Washington. Sediment Sampling Results -Summary Detected chemical contamination in the permitted dredge area (DMMU-I) is very limited. Testing results are below DMMP fresh water and marine screening levels for I Inyd & A<;soclates. Inc Page 23 of30 all parameters (see Section 3.0 Chemical and Physical Data). Nevertheless, some motor oil range petroleum hydrocarbon was detected at 39 mg/kg (dry basis). Diesel range petroleum product was detected in the composite sample at 8.3 mg/kg (dry basis). Additionally, traces of Polynuclear Aromatic Hydrocarbons (PAHs) were detected. For example, benzo(a)pyrene was detected at 24 ug/Kg (dry basis). Based on Analytical Testing Data and Screening Level comparisons, sediments to be dredged in 2017 at the project site are suitable for open-water disposal. Llo;.d & i\:-':-'oclates.

BACKGROUND / HISTORY This Biological Assessment (BA) was prepared to obtain a modification of the Cugini's existing U.S. Army Corps of Engineers (USACE) programmatic permit (NWS-2007-1019-NO) which allows maintenance dredging activities in the amount of 2,000 to 4,000 cubic yards from a 1O,000-square- foot area of Lake Washington near the May Creek delta over a lO-year period (Figure 1). The proposed action is to allow dredging of up to an additional 2,700 cubic yards (up to 14,000 square feet of lakebed) adjacent to the existing permitted dredge prism (Appendix A). This expansion of the dredge prism would align it with the dredge area permitted by the City of Renton in 2006; expand the current permitted dredge footprint to the west by approximately 160 feet (to the Inner Harbor Line), and align the dredge footprint along the property line on the north of Lot A (Appendix A, Sheets 1 through 4). The purpose of this proposed expansion is to facilitate safe navigational access to the boathouse and promote future recreational uses. While periodic maintenance dredging to remove accumulated sediments has occurred within and near the May Creek delta for over 50 years, the proposed expanded dredging project addressed in this BA is focused on the zone shown in Appendix A, Sheets 1 through 4). Based on the project proponent's experience over the past 50 years, dredging of this area would be necessary every 3 to 5 years to maintain navigational depths and other project objectives. In addition to expanding the existing dredging prism, the proposed action would involve three environmental enhancements in the local area. These include placing 10 cubic yards of rounded river rock adjacent to the existing boat launch and boathouse to enhance shallow water habitat for fishes; removing two dolphins (6 creosote piles) at south side of Lot D and replacing them with two 12-inch-diameter galvanized pipe piles; and removing three large creosote pilings near the delta, coupled with the installation of a fish friendly float with grated decking.

Section 7 of the Endangered Species Act (ESA) of 1973 (as amended) directs federal departments and agencies to ensure that actions authorized, funded, and/or conducted by them are not likely to jeopardize the continued existence of any federally proposed or listed species, or result in destruction or adverse modification of critical habitat for such species. Section 7(c) of the ESA requires that federal agencies contact the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS), subsequently referred to as the Services, before beginning any construction activity to determine if federally listed threatened and endangered (T&E) species or designated critical habitat may be present in the vicinity of a proposed project. A BA must be prepared if such species or habitat are present. With respect to the proposed action, federal permits from the USACE would be needed to complete the project. The Services have determined that T&E species, including Puget Sound Chinook salmon, Puget Sound steelhead, and Coastal/Puget Sound bull trout may be present in the proposed project action area; therefore, this BA is required by the ESA to ensure that the proposed expanded dredging project would not jeopardize the continued existence or recovery of these listed species. This document also contains an Essential Fish Habitat (EFH) assessment in accordance with section 305(b)(2) of the Magnuson-Stevens Fishery Conservation and Management Act (MSA) (16 U.s.c. 1801, et seq.) and implementing regulations at 50 CFR 600. The MSA includes a mandate that NMFS identify EFH for federally managed marine fish. In addition, federal agencies must consult with NMFS on all activities, or proposed activities, authorized, funded or undertaken by the agency that may adversely affect EFH. The Pacific Fisheries Management Council (PFMC) has designated EFH for the Pacific salmon fishery, federally managed ground fish and coastal pelagic fisheries. The ESA consultation process can be used to address EFH (NMFS 2001). This BA addresses EFH for Chinook and coho salmon, which are the only MSA-managed species that may be present in the project area. Biological Assessment Page 2 Q:\Proiects\Barbee BA 2012\2012 Drat! BA\2012 BA OS2712_docx Cugini Property Boathouse Expanded Dredge Prism The objective of this BA is to review all pertinent and available information on the potential effects of the proposed project on MSA managed species, EFH, ESA listed T&E species, and associated critical habitats under NMFS and USFWS jurisdiction. Based on our analysis in Section V, the proposed project would likely cause a short-term negligible increase in turbidity/suspended sediment in the action area and a reduction in benthic invertebrates in the dredging zone. However, overall water quality would likely be improved over the long term through the removal of the toxic creosote pilings near the dredging area. Primary productivity and the fish forage base within the project vicinity would also be improved through the installation of a fish friendly float and the placement of additional "fish rock" along the Lake Washington shoreline. For these reasons, implementation of the conservation measures included in the proposed project would be expected to benefit listed Chinook, steel head, and bull trout. Take of any listed species is very unlikely, and designated Chinook and bull trout critical habitat would not be destroyed or adversely modified by the project. Therefore, the proposed project "may affect", but is "not likely to adversely affect" Chinook, steelhead, and bull trout. In addition, the proposed project would not adversely affect designated EFH for Chinook and coho salmon, and would not hinder a sustainable fishery for these two species. A. PROJECT AND FEDERAL ACTION HISTORY Dredging of the May Creek delta and boathouse area has occurred for over 50 years on a 3-to 4- year cycle, depending on the volume of sediment accumulation. Since the delta area was dredged in 2002, an estimated 20,000 to 24,000 cubic yards have been deposited at the delta in Lake Washington. The most recent dredging occurred in 2011. Approximately 3,000 to 4,000 cubic yards of sediment have been removed during each dredging cycle. The dredged material was previously stockpiled on upland areas of the Barbee Mill property (owned by the Cugini family) and sold as clean construction fill material. Previous consultations with the USACE were completed for May Creek delta dredging and for bark debris removal in Lake Washington adjacent to Barbee Mill. Bark removal work was voluntarily undertaken to restore aquatic habitat under lease agreements with the Washington Department of Natural Resources. Most recent consultations for these projects at the Barbee Mill site (summarized in Table 1) resulted in a "not likely to adversely affect" determinations for listed Chinook salmon, steelhead, and bull trout.

DESCRIPTION OF THE ACTION AND ACTION AREA A. FEDERAL ACTION AND LEGAL AUTHORITY It is anticipated that the USACE would be the lead federal agency for this ESA consultation, as USACE permits are the only federal approvals (i.e., federal action) required for the proposed dredging project. Therefore, this BA follows the USACE BA template. This BA is required by the ESA to ensure that dredging actions that may be authorized by the USACE under section 404 of the federal Clean Water Act are not likely to jeopardize the continued existence of any federally proposed or listed species, or result in destruction or adverse modification of critical habitat. B. PROJECT DESCRIPTION The proposed action would involve amending the current USACE programmatic permit to allow dredging of an additional 2,700 cubic yards of sediment (1,400 square feet of lakebed) in an area located adjacent to the existing permitted dredge prism (Appendix A). This expansion of the dredge prism would align it with the Cugini property and inner harbor lines, facilitate safe navigational access to the boathouse, and promote future recreational uses. The current permit reference is NWS-2007-1019-NO. For decades, the Barbee Mill site (owned by the Cugini family) and May Creek delta have been affected by ongoing development in the upper May Creek valley. Upstream development has resulted in higher peak flood flows due to increased impervious surface in the watershed. Peak flows have increased approximately 15 to 20 percent compared to predevelopment conditions for the 2-, 25-, and lOO-year flood event return intervals (King County 2001). In addition, this increased run-off has resulted in severe bank erosion and sediment transport from the upper basin, which is deposited in the May Creek delta adjacent to the Barbee Mill. Subsequently, wave action in Lake Washington transports fine sediment from the delta to the boathouse area, which is located to the south of the May Creek delta. Dredging of the May Creek delta and Cugini property boathouse area has occurred for over 50 years on a 3-to 4-year cycle, depending on the volume of sediment accumulation. As is allowed under the existing permit, a small dredge and clamshell bucket would be used and the material would be disposed of at an approved upland location. The sediment from this area has been tested in the past using the procedures speCified by the Dredged Material Management Program (DMMP) and the DMMP has determined that all of the material is suitable for appropriate beneficial use. Under the proposed action, dredging events would continue to occur in both the existing and expanded dredge prisms over a 3-to 5-day period every 3 to 5 years within the approved in-water work period. Up to a maximum of 2,700 cubic yards of additional sediment would be removed to accomplish the desired navigational depth profile. Dredging would deepen the expanded dredge prism by approximately 10 feet over 1,400-square-feet of lake bed (Appendix A). Periodic evaluation of sediment depth would trigger future dredging activities. As is currently permitted, accumulated sediments would be removed with a small dredge and clamshell bucket. Portions of the work may also be conducted with a long-reach excavator from the land or an excavator mounted on a fenced flat barge. Use of any other type of dredge would require prior approval from Biological Assessment Page 4 Q:\Projects\Barbee BA 2012\2012 Draft BA\2012 HA 082712.docx Cugini Property Boathouse Expanded Dredge Prism the USACE and Washington Department of Ecology (WDOE). Sediments would be loaded on a barge, transported, and off-loaded at an approved fill material stockpile zone for beneficial upland uses. Based on monitoring records from previous and currently permitted dredging actions at the site, conservation measures such as silt curtains to reduce turbidity should not be required. During 2002 dredging, the highest turbidity values recorded were less than 7 NTU. However, turbidity would be monitored during future dredging. Conservation measures, such as silt curtains, would be deployed as necessary fol[owing conditions set by the WDOE 401 certification for this project. [t is anticipated that the WDOE would require the deployment of a silt curtain if turbidity in the dredging zone exceeds 10 NTU above background levels. To enhance aquatic habitat in the project vicinity, the project proponent is also proposing to place an additional 10 cubic yards of 3-to 6-inch diameter "fish rock" along the lake Washington shoreline just south of the existing boathouse. The Cuginis would also extract and replace three existing creosote piles with two 8 inch diameter galvanized pipe piles and demolish and rep [ace the existing solid-surface 38-foot float with a grated float that is 24 feet long. The grated float would increase light transmission to the shallow water habitat. Grating specifications would comply with previously approved permit conditions for light transmission. [n addition to these measures, two dolphins (six creosote piles) at the south side of lot D would be extracted and replaced with two 12- inch diameter galvanized pipe piles. Piles would be pulled concurrent with the Area 2 enhancement work. As previously approved in the existing USACE permit, all creosote treated pilings would be cut into 4-foot lengths and disposed of in an approved upland landfi[l, consistent with existing permit requirements. Timing and Duration of Work Conducting all dredging and habitat enhancement work addressed in this BA within the existing NMFS approved in-water work period and implementing conservations measures detailed in this BA, would minimize or avoid impacts to listed fish species and their habitat in the action area. Detai[ed information for each project element is presented be [ow. The NMFS approved lake Washington in- water work time, which is designed to limit impacts to aquatic species, is Ju[y 16th to September 15th (NMFS 2008). Consistent with the existing permit, the proposed expanded dredge area would be dredged during this time frame, once approximately every 3 to 5 years over the existing permit's lO-year period. Sediment Disposal Sediments from the expanded dredge area would be dredged and transported by barge for off- loading at the adjacent Quendall Termina[s located immediately north of the delta. Dredged materials would be loaded into a dredge scow and unloaded with a long-reach excavator. Sediments would be used for upland beneficial uses, subject to an assessment of sampling results and chemical analysis. All debris ([arger than 2 feet in any dimension) would be removed from the dredged sediment prior to disposal. Bio[ogical Assessment Page 5 Q:\Projects\Harbcc 8A 201212012 Draft BA\2012 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism Conservation Measures Conservation measures are activities that the applicant would implement to avoid or minimize take of listed species and avoid or reduce impacts to their habitat. As part of the proposed action, the applicant would implement several conservation measures to minimize impacts to listed species. These measures are consistent with the existing dredge permit and are listed below. The applicant would: 1. Limit the duration of in·water work to the extent necessary to accomplish project objectives, estimated to be 7 to 10 days of work, once every 3 to 5 years. Work would be conducted during the approved NMFS Lake Washington in-water work time (July 16 to September 15). 2. Monitor water quality during each dredging event in accordance with the WDOE 401 water quality certification. Monitoring would be conducted at least daily within and adjacent to the dredging zone in order to determine the background turbidity level and any increases caused by dredging. 3. If construction induced turbidity levels in the work zone exceed 10 NTU over background levels, modify dredging activities by employing standard methods such as silt curtains to reduce the opportunity for fish exposure to turbidity. Dredged material would not be stockpiled on a temporary or permanent basis below the ordinary high water line. 4. If oil or other unknown substances appear on the water surface or in dredged material while equipment is being operated, cease operations immediately to identify the source of the contaminant and remedy the problem. If necessary, use an oil absorbent boom secured to a debris boom to encircle the work zone to capture sheen or potential floating debris. 10. Avoid dredging along shoreline slopes and shallow water habitat along the shoreline north of the dredging zone to protect nearshore habitat that may be used by rearing Chinook salmon or steelhead. 11. Conduct a post-dredge bathymetry survey to ensure that only the specified amount of material was removed. 12. Confine dredging impacts to the minimum area necessary to complete the project. During dredging, the Cuginis would have a boat available on site at all times to retrieve debris from the water. 13. Prepare and make available a summary report documenting monitoring activities immediately following the dredging to confirm that these conservation measures were implemented. 14. Comply with any additional measures that are currently required in the existing Biological Opinion (NMFS 2008) and Section 401 Water Quality Certification (WDOE 2008).

RELATION OF PROPOSED PROJECT TO OTHER ACTIONS The proposed expansion of the dredge prism is directly related to the existing (permitted) dredging activities occurring just south of the May Creek delta. The purpose of this proposed expansion is to align it with the existing property and inner harbor lines, facilitate safe navigational access to the boathouse, and promote future recreational uses. D. PROJECT AREA AND ACTION AREA DEFINED The action area includes all areas to be affected directly or indirectly by the proposed federal action and not merely the immediate area involved in the action (50 CFR §402-02). The action area for this proposed project is in the Lake Washington shoreline corresponding to the immediate vicinity of 3901 Lake Washington Boulevard Avenue, near Renton (Township 24 North, Range 5 East, Section 32). The action area includes EFH for Chinook salmon and coho salmon. Appendix A shows the proposed expanded dredging zone. The removal of up to a maximum of 2,700 cubic yards of sediment would disturb approximately 14,000 square feet of substrate in Lake Washington. In order to encompass all indirect effects, such as increased turbidity during dredging, the action area for this project encompasses the lower portion of May Creek and southern Lake Washington within approximately one half mile of the May Creek delta (Figure 2). It is anticipated that the one half mile action area is more than sufficient to encompass small and temporary increases in turbidity during dredging based on water quality monitoring during previous dredging in the delta.

SPECIES LISTS FROM THE SERVICES (NOAA FISHERIES AND USFWS) A list of federally listed endangered, threatened, proposed, and candidate species and critical habitat that may occur in the action area was compiled using the NMFS and USFWS electronic species list websites and critical habitat designations. The USFWS and NMFS websites were accessed on June 1, 2012. Identification of Listed Species and ESU/DPS On March 24, 1999, the NMFS listed Chinook salmon (Gncorhynchus tshawytscha) in the Puget Sound Evolutionarily Significant Unit (ESU) as threatened under the ESA (64 FR 14308), and the listing was reaffirmed on June 28, 2005. The ESU includes all naturally spawned populations of Chinook salmon from rivers and streams flowing into Puget Sound including the Straits of Juan De Fuca from the Elwha River, eastward, including rivers and streams flowing into Hood Canal, South Sound, North Sound and the Strait of Georgia in Washington, as well as twenty-six artificial propagation programs. Puget Sound steel head (G. mykiss) were listed as threatened under the ESA on May 11, 2007 (72 FR 26722). The Distinct Population Segment (DPS) includes all naturally-spawned anadromous winter- run and summer-run steel head populations in streams in the river basins of the Strait of Juan de Fuca, Puget Sound, and Hood Canal, Washington, bounded to the west by the Elwha River (inclusive) and to the north by the Nooksack River and Dakota Creek (inclusive), as well as the Green River natural and Hamma Hamma winter·run steelhead hatchery stocks. The Coastal!Puget Sound bull trout DPS was listed as threatened under the ESA on November 1, 1999 (63 FR 31693). The Coastal-Puget Sound DPS comprises all Pacific coast and Puget Sound bull trout populations within Washington State, including the Snohomish River and its tributaries. This population segment is geographically segregated from other subpopulations by the Pacific Ocean and the crest olthe Cascade Mountain Range. It is significant to the species as a whole because it is thought to contain the only anadromous forms of bull trout in the coterminous United States. Puget Sound/Strait of Georgia coho salmon (0. kisutch) are not listed under the ESA; however, they were classified as a Species of Concern on April 15, 2004 due to specific risk factors. The ESU includes all naturally spawned populations of coho salmon from drainages of Puget Sound and Hood Canal, the eastern Olympic Peninsula (east of Salt Creek), and the Strait of Georgia from the eastern side of Vancouver Island and the British Columbia mainland (north to and including the Campbell and Powell Rivers). excluding the upper Fraser River above Hope. Table 2 summarizes the federally-listed, proposed, and candidate fish and marine mammal species that are known to occur near the action area or that may be potentially affected by the propose action. The table also indicates whether critical habitat or EFH has been designated or proposed for each species.

Designated critical habitat Puget Sound Chinook salmon includes Lake Washington (freshwater rearing and freshwater migration); however, no critical habitat is designated in May Creek. On January 19, 2007, the NMFS adopted a final ESA recovery plan for Puget Sound Chinook salmon (Shared Strategy Development Committee 2007). The plan includes specific protection and restoration actions for each watershed in the Puget Sound region as well as actions at the regional E5U scale. The action area contains juvenile Chinook salmon rearing and migration primary constituent elements (PCEs) and adult Chinook salmon migration PCEs. ESA critical habitat was proposed by the USFWS for the Coastal/Puget Sound bull trout DPS on June 24,2004 (50 CFR Part 17). Proposed critical habitat for the Coastal/Puget Sound DPS includes Lake Washington, but does not include any Lake Washington tributaries, except the upper Cedar River. Lake Washington is proposed as foraging, migration, and overwintering (FMO) critical habitat for bull trout. Proposed Critical Habitat for Puget Sound Steelhead is currently under review by the NMFS. A recovery plan has not yet been developed for the Puget Sound Steelhead DPS. The MSA defines EFH as those waters and substrate necessary for fish use in spawning, breeding, feeding, or growth to maturity. MSA manages species that may occur in the action area, including Chinook and coho salmon. Freshwater EFH for these salmon species includes all those streams, lakes, ponds, wetlands, and other water bodies currently, or historically accessible to these species in Washington, Oregon, Idaho, and California. Lake Washington is designated EFH for Chinook and coho salmon. There are four major components of freshwater EFH for salmon including 1) spawning and incubation; 2) juvenile rearing; 3) juvenile migration corridors; and 4) adult migration corridors Biological Assessment Page 10 Q:\Projects\Barbee BA 2012\2012 Draft RA\20 12 AA 082712,docx Cugini Property Boathouse Expanded Dredge Prism and adult holding habitat. The components of EFH in the action area include juvenile rearing and migration corridors, and adult migration corridors and holding habitat. B. DESCRIPTION OF SPECIES Chinook Salmon Status ofthe ESU The Puget Sound Chinook salmon Evolutionarily Significant Unit (ESU) has been defined to include all PS Chinook salmon populations residing below impassable natural barriers (e.g., long-standing natural water falls) in the Puget Sound region from the Nooksack River to the Elwha River on the Olympic Peninsula, inclusive. The status of individual populations within Puget Sound is assessed based on their abundance, productivity, diversity, and spatial structure. Within the action area in Lake Washington, there are two native populations (the North Lake Washington population and the Cedar River population) that use the area from rearing and migration. A third population, the Issaquah stock, is not included in the assessment because they are a non-native stock from the Issaquah Hatchery that has been in operation since the 1930s (WDFW 2004). Overall abundance ofthis ESU has declined substantially from historical levels, and many populations are small enough that genetic and demographic risks are likely to be relatively high (March 9, 1998, 63 FR 11494). Historic abundance has been estimated to be approximately 609,000 adult returns (Myers et al. 1998), while average present day (1998-2002) abundance of natural origin spawners is 30,182 fish (NMFS 2005). NMFS (Good et al. 2005) listed approximately 331 geometric mean spawners in North Lake Washington population and 327 in the Cedar River population, and no estimates of historical abundance for comparison. The general trend in the abundance for the North Lake Washington Tributary Chinook salmon has remained generally consistent, with escapements between 200 and 500 adults (WDFW 2004). The Cedar River Chinook salmon have shown a long-term negative trend in escapements and chronically low escapement values (WDFW 2004). The lambda (productivity estimate) for North Lake Washington Chinook (short term trend) is 1.07 (±0.07) (Good et ai., 2005), indicating the population is just replacing itself. For the Cedar River, short term lambda is (0.99±0.07) also indicating the population is probably just replacing itself. Significant population growth would require an increase in productivity. For salmon recovery, the target goal lambda amount is 3.4 to increase abundance to a level that would remove the populations from the threat of extinction. Genetic analysis of the three populations in the Lake Washington basin indicated that the North Lake Washington Tributary population and the Cedar River Chinook are significantly different (WDFW 2004). Therefore, the genetic differentiation between the two populations increases the possibility for recovery when faced with an environmental change and an increase of available habitat. Life History and Habitat Requirements Throughout their range, Chinook salmon exhibit diverse and complex life history strategies. Differences exist in age at seaward migration; freshwater, estuarine, and ocean residence; and in age and season of spawning migration (Healey 1991, page 314; Myers et al. 1998, page 9). Most of Biological Assessment Page 11 Q:\Pro.lects\Barbee BA 2012\2012 Dra!t BA\2012 IJA 082712.doo. Cugini Property Boathouse Expanded Dredge Prism this variation is exhibited in two distinct behavioral forms commonly referred to as stream-type and ocean-type {Healey 1991, page 314}. Stream-type Chinook rear in freshwater for a year or more before migrating to sea, perform extensive offshore migrations, and return to their natal river in spring or summer, several months prior to spawning. Ocean-type Chinook typically migrate to sea in their first year of life, only a few months after emergence, remain in nearby coastal areas, and normally return to their natal river in the late summer or fall, a few days or weeks before spawning. Ocean residence for both stream-type and ocean-type Chinook usually ranges from 1 to 6 years; however, a small proportion of yearling males, called "jacks" mature in freshwater or return to freshwater after 2 to 3 months in salt water. Chinook salmon in the Puget Sound ESU typically exhibit an ocean-type life history; however, a number of spring-run populations in the ESU include a high proportion of yearling smolt emigrants. Adult Chinook salmon in the Puget Sound typically return to freshwater in August and spawn in the lower and middle reaches of rivers from late September through January {WDF et al. 1993}. Preferred water temperatures for spawning range from 42.1 and S7"F {Reiser and Bjornn 1979}. Often, the preferred spawning sites are located near deep pools and in areas with abundant instream cover. Adequate spawning area, abundant clean gravel {O.S to 4 inches in diameter}, a relatively stable stream channel (with minimal bedload movement), and sub-gravel flow are very important in the selection of redd sites {Healey 1991, page 323}. Depending on water temperature, incubation takes between 90 and 150 days. While rearing in freshwater, juvenile Chinook are normally associated with low gradient, meandering, unconstrained stream reaches. As they grow, submerged and overhead cover in the form of rocks, submerged aquatic vegetation, logs, riparian vegetation, and undercut banks provide food and shade and protect juveniles from predation. When adult Chinook return to spawn, they often rely on deep pools for resting. These pools provide an energetic refuge from river currents, a thermal refuge from high summer and autumn water temperatures, and protection from potential predators. Chinook stocks in Lake Washington exhibit ocean-type life history patterns, with juveniles typically migrating to sea within the first three months after emergence. However, juveniles have also been found to delay seaward migrations by rearing in Lake Washington for extended time periods {Wydoski and Whitney 1979}. In Lake Washington, Tabor et al. {2004} found that juvenile Chinook salmon prefer shallow, low-gradient delta and shoreline habitats composed of sand and gravel substrates with overhanging vegetation and small woody debris accumulations. The preferred temperature range for Chinook salmon fry ranges from 54 to S6.8°F {Reiser and Bjornn 1979}. After a variable freshwater residence time, Chinook salmon juveniles migrate to estuaries. Migrations occur primarily during spring and early summer, but continue at lower levels through the fall {USFWS 1983}. Chinook salmon in the Skagit River estuary occupied the inner estuarine salt marshes for 2 to 3 days before emigrating farther out in the estuary {USFWS 1983}. Smolts congregated in tidal streams at low tide, with the majority of fish observed in deep, slow water over soft substrates {USFWS 1983}. The highest nearshore juvenile Chinook salmon densities occurred in tidal areas without any freshwater influence {Shepard 1981}. Factors of Decline Threats to the Chinook salmon include watershed development, such as forest practices, mining, agricultural land use, urbanization, hydropower development and water manipulation and Biological Assessment Page 12 Q:\Projects\l:3arbee BA 2012\20 12 Draft BA\20 12 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism withdrawal. Over-fishing, artificial propagation and introduction of nonnative species have also impacted Chinook salmon. Forest practices, mining, agricultural land use, urbanization, hydropower development and water withdrawal have resulted in increased sedimentation, changes in flow regimes and channel morphology, decrease in water quality and quantity, loss of riparian habitat, loss of large woody debris (LWD), and loss of LWD recruitment, higher water temperatures, decreased gravel recruitment, reduction in pools and spawning and rearing areas, rerouting of stream channels, degradation of streambanks and loss of estuarine rearing areas (Bishop and Morgan 1996; Myers et al. 1998). These changes have affected the spawning and rearing environment of Chinook salmon. Harvest, hatchery practices and the introduction of nonnative species have also impacted the expression of the varied life history strategies of Chinook salmon within the ESU. Current and future development pose many risks to the Chinook salmon populations in Lake Washington, primarily through increased water pollution and further habitat degradation by such mechanism as increased impervious surface, which alters stream hydrology causing increased erosion and sedimentation of Chinook spawning grounds. A detailed discussion of Chinook limiting factors in the Lake Washington basin is given in Kerwin (2001). In addition to extensive shoreline development, other factors that can compromise the survival of juvenile Chinook salmon include poor water quality and high water temperatures in the Ship Canal and Ballard Locks. All juvenile and adult anadromous salmonids must pass through the Ship Canal during migrations to and from saltwater. The significant differences in water temperature and salinity encountered at the Ballard Locks require a rapid transition by the fish and may cause severe stress. For example, recorded delays in egg development in returning adult salmon may be connected to the temperature transition when entering freshwater and prolonged exposure to high temperatures in the Ship Canal (Kerwin 2001). In addition, the sharp demarcation between the fresh and saltwater environments at the Lake Washington outlet is likely a stressor for juvenile salmonid out-migrants. The Locks are also a predation bottleneck. Heavy seal predation on adult salmon at the Locks is a common and recurring problem. Hatcheries continue to pose risk to natural spawning Chinook salmon in Lake Washington, although hatchery impacts are becoming increasingly recognized and elforts are being made to reduce hatchery effects listed populations. Several hatcheries and hatchery programs exist in the Lake Washington basin. Releases offall-run Chinook salmon in the Lake Washington system accounted for about five percent of all Puget Sound releases from 1991 through 2000, with about 2.6 million fish per year. In Puget Sound, hatchery fish greatly outnumber natural origin fish in terms of juvenile out-migrants and adult returns (NMFS 2003). Detailed descriptions of harvest rates for Lake Washington Chinook stocks are provided in (NMFS 2003). While harvest rates frequently change, the harvest rate of Lake Washington Chinook has diminished over time. The total exploitation rate for Chinook salmon returning to the Lake Washington watershed was 67 percent from 1983 through 1996, and 26 percent from 1997 through 2000. Local Stock Information The primary Chinook salmon stock in the project vicinity (the southern portion of Lake Washington) originates from the Cedar River. The Cedar River Chinook run, although a naturally spawning population without current supplementation from hatchery stocks, is not native to Lake Biological Assessment Page 13 Q-\Projects\Barbee BA 2012\20 [2 Draft BA \2012 BA 081711.do(:'i. Cugini Property Boathouse Expanded Dredge Prism Washington, May Creek is not thought to have a self-sustaining Chinook salmon run and individuals using the stream are likely strays from the Cedar River, Chinook are reported to use the lower three miles of May Creek for limited spawning and rearing (Lucchetti 2002), Lucchetti (2002) rated the lower May Creek sub-basin (from mouth to RM 3.0) as moderate to high for spawning habitat. This rating signifies areas in which Chinook are known to spawn and that are characterized by adequate flows and physical attributes (e.g., channel size, gradient, and substrate) that typically support Chinook spawning (Lucchetti 2002). According to King County (2011). nearly all spawning occurs in the lower two miles of May Creek, though spawning has been observed up to RM 3.0. The number of Chinook observed in May Creek varies between zero and 12 fish annually (pers. comm. Aaron Bosworth, WDFW, November 15, 2010, as cited in King County 2011). Adult Cedar River Chinook salmon enter Lake Washington through the Ballard Locks from late June through September, with the run peaking in late August. Spawning occurs from mid-September through mid-to late-November, with a peak in early to mid-October (WDF et al. 1993). In the Cedar River, fry probably begin to emerge in February and continue through March and perhaps April (City of Seattle 2000), which is also probably true in May Creek as well. Unlike most systems in which juvenile Chinook rear in rivers and estuaries, juvenile Chinook in Lake Washington rear in the littoral areas of the lake from January to July. While rearing in the south end of Lake Washington, the nocturnal distribution of juvenile Chinook salmon appears to be related to slope, substrate, and depth. Tabor et al. (2004) studied juvenile Chinook salmon use of shoreline habitats in Lake Washington and found that juvenile Chinook were concentrated in very shallow water, approximately 1,3 feet in depth, and prefer low gradient shorelines and deltas with substrates composed of sand and gravel. In comparison to lake shore reference sites, the delta sites had a higher density of juvenile Chinook salmon. On average, the delta sites had almost twice as many fish as the lake reference site. Of the delta sites studied, Tabor et al. (2004) found that juvenile Chinook appeared to use low gradient and shallow deltas that were close to natal streams (such as the Cedar River). Tabor et al. (2004) also found that juvenile Chinook had no preference for woody debriS piles alone; however, they did show a preference for woody debris piles in combination with overhanging vegetation. In fact, over 80 percent of juvenile Chinook observed during the study were found along shallow sites in association with overhanging vegetation and small woody debris. The majority of juvenile Chinook observed by Tabor et al. (2004) were concentrated in the south end of Lake Washington from February to May, with peak abundance occurring in May. The last shoreline survey was conducted on July 14, when only one juvenile Chinook was observed out of five sample sites. The lower 912 feet of May Creek and the May Creek delta (convergence pool) were included in the study sites evaluated by Tabor et al. (2004). Tabor et al. (2004) also surveyed a lake reference site located approximately 2,000 feet south of the May Creek delta (the Kennydale Beach Park swim beach). In March of 2002, only two Chinook salmon were observed during the surveys, one in the convergence pool and one in a pool in May Creek. The density of juvenile Chinook salmon was Similar between the lake reference site and delta area. Juvenile coho salmon were also present primarily in the convergence pool, while large trout primarily occupied the upstream pools. Small resident trout were scattered throughout the study Biological Assessment Page 14 Q:\Pr~iects\l::3arbee SA 20 12\20 12 Draft BA\20 12 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism reach. Tabor et al. (2004) noted that predation of juvenile Chinook salmon by large trout has been documented in Lake Washington (Tabor and Chan 1996) and the Cedar River. Few predatory fish were present in the shallower deltas, which were used by up to 10 times more Chinook compared to the May Creek delta. Based on habitat preference, Tabor et al. (2004) hypothesized that the presence of large trout and large sculpin in the large tributaries may inhibit the use of the convergence pool and other stream habitats by Chinook. It may be that the lack of juvenile Chinook in the deep delta habitat has more to do with this habitat type being preferred by predatory fish, and not that deep delta habitats are not "good" Chinook habitat. Steel head Status ofthe DPS The NMFS defined the Puget Sound Steelhead DPS to include naturally spawning steelhead stocks below natural and manmade impassable barriers, in streams and rivers ranging from the Canadian border (Nooksack River basin), south through Puget Sound and Hood Canal, north and west to the Elwha River, which empties into the eastern Strait of Juan de Fuca. The Puget Sound 5teelhead are at risk of becoming endangered in the foreseeable future, and were listed as threatened on June 11, 2007 (72 FR 26722). The status of individual populations within Puget Sound is assessed based on their abundance, productivity, diversity, and spatial structure. The two populations of steelhead found in lake Washington use the lake for migrating, holding and rearing. Early abundance analysis from catch records in 1889 indicate that the catch peaked at 163,796 individuals in 1895 (Little, 1898). Assuming a harvest rate of 30 to 50 percent, Little (1898) estimated that the peak run size ranged from 327,592 to 545,987 fish. In the 19905 the total run size for major stocks in this DPS was greater than 45,000, with total natural escapement of about 22,000, a fraction of the 1889 abundance. The abundance treat for the Cedar River population is decreasing. Counts between 1980 and 2004 estimate an escapement of 137.9 natural spawners, and more recent data (2000-2004) has the estimates at 36.8, showing a steep decline (Hard et al. 2007). The Lake Washington population shows a similar declining trend with 308.1 natural spawners between 1980 and 2004, and 36.8 between 2000 and 2004 (Hard et al. 2007). To estimate existing productivity in Lake Washington steelhead, Scott and Gill (2006) used escapement data or indices of escapement from the previous eight years to create a time series. Population viability analyses were conducted under the assumption that only anadromous spawners contribute to the abundance of each population. This assumption may result in estimates of extinction that are too high because the presence of resident forms of O. my kiss (rainbow trout) may reduce the likelihood of extinction. The Lake Washington winter-run steelhead last escapement data was listed at 44, with a growth rate estimate of -0.16, indicating a decrease in productivity. The relative risk of extinction for populations of steelhead in the Puget Sound region is very high, because productivity is poor. More recent productivity analysis included lambda calculations, showing Cedar River steelhead lambda at 0.808 (±0.004), and Lake Washington steel head lambda at 0.802 (±0.002) (Hard et al. 2007), supporting Scott and Gill's (2006) productivity decline. Allozyme analysis of steelhead sampled in the Cedar River in 1994 clusters them with winter steelhead in the Green, White, and Puyallup rivers, and with some Snohomish basin steel head stocks (WDFW 2004). The Cedar River population is a distinct population that has undergone minimal hatchery introgression (Hard et al. 2007). Biological Assessment Page 15 Q \ProjectslBarbee BA 2012\2012 Draft BAllO 12 HA 082712.uocx Cugini Property Boathouse Expanded Dredge Prism The status of the Lake Washington winter steelhead was defined in the SaSI report (WDFW 2004). Based on the chronically low escapement and short-term severe decline in escapements, the stock status declined from "depressed" in 1994 to "critical" in 2002. Past hatchery practices by WDFW included planting of steelhead fry throughout tributaries in the Lake Washington/Lake Sammamish Basin and were unsuccessful in producing return adult spawners. The Cedar River has a naturally spawning population of steelhead and weekly surveys are conducted annually to assess abundance. Redd counts have been steadily declining and 2010 surveys observed only one redd (pers. comm. Hans Berge, King County, November 22,2010, as Cited in King County 2011). Life History and Habitat Requirements Unless otherwise Cited, the following steelhead information is summarized from the federal register proposal to list Puget Sound steelhead as threatened (50 CFR Part 223). Steelhead is the name commonly applied to the anadromous form of the biological species Oncorhynchus mykiss, which includes rainbow trout). The present distribution of steelhead extends from Kamchatka in Asia, east to Alaska, and extending south along the Pacific coast to the U.S. Mexico border. O. mykiss exhibit a complex suite of life-history traits and can be anadromous (i.e. steelhead), or freshwater residents (rainbow or redband trout), and under some circumstances yield offspring of the opposite life-history form. Steel head juveniles generally migrate to sea at age 2 to 3, but can spend up to 7 years in freshwater. Peak outmigration to the sea is generally in the late spring and early summer. Steelhead generally spend 1 to 2 years at sea before returning to freshwater to spawn. O. mykiss may spawn more than once, whereas the Pacific salmon species are principally spawn once and die. As with most salmon ids, spawning typically occurs in streams where the water is cool, clear, and well oxygenated. The optimum spawning temperature for steel head is about 45°F, but they have been reported spawning at temperatures of 39 to 55°F. After emergence, steelhead fry form small schools and inhabit the margins of the stream. As they grow larger and more active, they slowly begin to disperse downstream. Steelhead prefer relatively small, fast flowing streams with a high proportion of riffles and pools. Most steelhead in their first year of life in riffles, but some larger fish also inhabit pools or deep fast runs. Instream cover such as large rocks, logs, root wads, and aquatic vegetation are very important for juvenile steelhead. This cover provides resting areas, visual isolation from competing salmon ids, food, and protection from predators. Often steelhead densities are highest in streams with abundant instream cover. The preferred water temperature for rearing steelhead ranges from 50 to 55°F. Factors of Decline Factors leading to the decline of the Puget Sound steelhead DPS are essentially the same as described previously for Puget Sound Chinook salmon and generally include habitat degradation by human disturbance such as forestry, agriculture, and general urbanization. Access to large reaches of spawning and rearing habitat has been blocked by dams and other manmade barriers. Existing regulatory mechanisms inadequately protect steelhead habitats as evidenced by the historical and continued threat posed by the loss and degradation. Hatchery practices have had genetic and life history effects, and lead to competition between naturally produced and hatchery fish. Over- harvest has also reduced abundance throughout the DPS. Biological Assessment Page 16 Q:\Pro)ects\Barbee BA 2012\2012 Drat( BAl.2012 HA OS2712.docx Cugini Property Boathouse Expanded Dredge Prism Local Stock Information Steelhead occurring in the project action area are part ofthe Lake Washington winter-run population (a native stock). They typically enterfresh water between November and April and spawn from mid-December through early June. Abundance of this stock has greatly declined over the past decade. The escapement goal for Lake Washington winter steelhead is 1,600 adult fish. However, from 2000 to 2004, the total Lake Washington winter steel head spawner escapement estimate ranged from only 20 to 48 fish, far below the escapement goal. WDFW considers the status of the Lake Washington stock as "critical" due to chronically low escapements and a short- term severe decline in escapement. Steelhead spawning occurs throughout the Lake Washington basin including the Sammamish River and its tributaries, Issaquah Creek, Coal Creek, May Creek, the lower Cedar River and several smaller Lake Washington tributaries. Survey data from 1984 through 1987 observed steelhead in the lower reaches of May Creek (Newcastle 2002 as cited in King County 2011). Data from the WDFW Salmon Scape website report that steelhead have been observed in the lower three miles of May Creek. Bull Trout Status of the DPS Bull trout, a member of the family Salmonidae, are a char native to the Pacific Northwest and western Canada. The species historically occurred in major river drainages in the Pacific Northwest from about 41°N to 60 0 N latitude, from the southern limits in the McCloud River in northern California and the Jarbidge River in Nevada to the headwaters of the Yukon River in Northwest Territories, Canada (Cavender 1978; Bond 1992). The Coastal-Puget Sound DPS comprises all Pacific coast and Puget Sound bull trout populations within Washington State. This population segment is geographically segregated from other subpopulations by the Pacific Ocean and the crest of the Cascade Mountain Range. It is significant to the species as a whole because it is thought to contain the only anadromous forms of bull trout in the coterminous United States. The USFWS conducted a 5-year review of the ESA listing status for bull trout in the coterminous United States that was published in April, 2008 (USFWS 2008a). This review includes the following observations: most population trends are unknown; there is a broad distribution of risk across the landscape; most core area bull trout populations are at high risk or at risk of extirpation; and the smallest core areas tend to be at a higher risk. Ultimately, the USFWS determined that "threatened" status remains warranted for bull trout, including the Coastal/Puget Sound DPS. The 5-year review final report indicated the USFWS would initiate a new, separate assessment to identify the individual status of each current DPS and determine if they need reorganization (possibly into smaller spatial units). This effort has not yet been completed. Although bull trout remain threatened in the Coastal/Puget Sound DPS, many of the local populations are apparently healthy enough to sustain angling and harvest in the Puget Sound region in several core areas. The Skagit and Snohomish River basins are seasonally open to angling and harvest of bull trout. This is a significant distinction, as on a rangewide basis, most core areas are closed to angling and harvest of bull trout. Biological Assessment Page1? Q,\Projl!ds\Barbee BA 2012\2012 Dratl 81\\2012 SA 082712 docx Cugini Property Boathouse Expanded Dredge Prism Life History and Habitat Requirements Throughout their range, bull trout are primarily freshwater species that exhibit both resident and migratory life-history patterns. The entire Iifecycle of the resident bull trout takes place in headwater streams. Resident fish spawn, rear, and live as adults generally in one headwater stream, although short migrations may occur. Migratory bull trout spawn and rear in headwater streams, then after two to four years rearing in their home stream, juveniles migrate downstream to larger rivers (fluvial) or lakes and reservoirs (adfluvial) where they grow to maturity. Migrations can range from a few miles to well over 50 miles (Goetz et al. 2004). Mature adults migrate back upstream to spawn in headwater reaches. There is increasing evidence that several coastal and Puget Sound popUlations have an anadromous or amphidromous component in Washington (Rieman and Mcintyre 1993; Kraemer 1999; Goetz et al. 2004; Yolk 2000; Goetz et al. 2004). Adult anadromous char are thought to prey primarily on fish. A study by Brenkman (2002) at the mouth of the Hoh River on the Olympic Peninsula found that surf smelt (Hypomesus pretious) was the primary prey item and was found in 96 percent ofthe stomachs analyzed; other species included herring (Clupea harengus pal/asi), sand lance (Ammodytes hexapterus) and sculpin (Cottus spp.). Other limited stomach content work and feeding observations in Skagit Bay and Port Susan also indicate that anadromous char feed most commonly on surf smelt, and other fish such as herring, sand lance, pink and chum salmon fry, and a number of invertebrates (Kraemer 1999). Kraemer (1999) and Brenkman (2002) suspected the distribution of char in marine waters is closely tied to the distribution of forage fish, especially spawning beaches for surf smelt and herring. Bull trout spawning occurs in the fall from late August into December (timing varies based on local conditions) and is thought to be correlated with particular flows, water temperatures, and photo period. Peak spawning usually occurs in September and October for most populations (Brenkman et al. 2001). Bull trout spawning generally occurs when water temperature drops below 48"F. Bull trout spawn in substrate ranging from large sand to gravel over 2 inches in diameter. In western Washington, bull trout spawning occurs above an elevation of 1,000 feet or in streams with very cold temperatures similar to high elevation streams (Kraemer 1999). Fry emerge from spring into the summer months (McPhail and Murray 1979). Mature adult bull trout can spawn more than once in a lifetime. First spawning is often noted after age four, with individuals living ten or more years (Rieman and Mcintyre 1993). Sexual maturity for both sexes has been documented in fish smaller than 6 inches fork length in resident populations (Hemmingsen et al. 2001). Bull trout appear to have more specific habitat requirements than other salmon ids (Rieman and Mcintyre 1993), requiring cold clean water and a high degree of habitat complexity (Dambacher et al. 1992; Rieman and Mcintyre 1993). Water temperatures over approximately SO"F are thought to limit their distribution; however, bull trout may be able to migrate through reaches with elevated water temperatures for short durations. Factors of Decline Bull trout are threatened by habitat degradation and fragmentation from past and ongoing land management activities such as mining, road construction and maintenance, timber harvest, hydropower, water diversions/withdrawals, agriculture, and grazing. Bull trout are also threatened by interactions and hybridization with introduced non-native fishes such as brook trout (Sa/ve/inus fontinalis) and lake trout (Sa/velinus namaycush). Although some strongholds still exist, bull trout Biological Assessment Page 18 Q \Projects\Barbee BA 2012\2012 Draft RA\20 12 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism generally occur as isolated sub-populations in headwater lakes or tributaries where migratory fish have been lost. Although the bull trout distribution in the Coastal/Puget Sound DPS is less fragmented than the Columbia River DPS, bull trout subpopulation distribution within individual river systems has contracted and abundance has declined. The decline of the Coastal/Puget Sound bull trout DPS has been attributed to habitat degradation, migration barriers, interaction with introduced species, water quality degradation, and past management practices. CommerCial and recreational fisheries also impact native char populations in Puget Sound. Native char are occasionally caught in sport and commercial fisheries in Puget Sound, as well as by in-river net fisheries. They are common in nearshore marine areas of Puget Sound from Everett north, and are vulnerable to beach seine and set net fisheries. Current and future population pressures on bull trout in Puget Sound and Lake Washington are the same as those listed for Chinook. Local Stock Information The following Lake Washington bull trout information is summarized from USFWS (2004) unless otherwise cited. The Cedar River watershed upstream of the Masonry Dam supports the only known self-sustaining population of bull trout in the Lake Washington basin. The Chester Morse Lake bull trout core area is located within the Cedar River in the upper reaches of the Cedar River drainage, upstream of a natural migration barrier at Lower Cedar Falls (river mile 34.4). The level of emigration of bull trout occurring from Chester Morse Lake to the lower Cedar River is unknown. The only means for bull trout to leave the reservoir complex and pass to the lower Cedar River is during use of the emergency spill gates and/or the smaller spillway near the south end of the Masonry Dam. These gates are rarely opened except under emergency conditions of high reservoir elevation (e.g., 1990 flood) or for special operational purposes. It is presumed impossible for live fish to pass through the other structure used to release water from Masonry Pool (Masonry Dam spill valve/Howell-Bunger valve) at the base of the Masonry Dam. It is possible that bull trout do successfully pass through the spill gates when water is released and thereby gain access to the 'canyon reach' and the lower Cedar River, but no accurate estimate of numbers of fish passing the dam has been made. No spawning activity or juvenile rearing has been observed and no distinct spawning populations are known to exist in Lake Washington outside of the upper Cedar River above Lake Chester Morse. The potential for spawning in the Lake Washington basin is believed to be very low as a majority of accessible habitat is low elevation, below 500 feet, and thus not expected to have the proper thermal regime to sustain successful spawning. However, there are some coldwater springs and tributaries that may come close to suitable spawning temperatures and that may provide thermal refuge for rearing or foraging during warm summer periods. These include Rock Creek (tributary to the Cedar River below Landsburg Diversion) and Coldwater Creek, a tributary to Cottage Lake Creek immediately below Cottage Lake. In addition, the upper reaches of Holder and Carey creeks, the two main branches of Issaquah Creek, have good to excellent habitat conditions and may hold potential for bull trout spawning due to their elevation and aspect. However, despite survey efforts by King County (Berge and Mavros 2001), no evidence of bull trout spawning or rearing has been found. The connection with the Chester Morse Lake core area is one-way only, and currently the level of connectivity with other core areas is unknown. However, a number of observations of subadult and adult sized bull trout have been made in Lake Washington and at the Ballard Locks (Shepard and Biological Assessment Page 19 Q:\ProjecLs\Barbee SA 2012\2012 Draft BA\20 12 SA 082712 docx Cugini Property Boathouse Expanded Dredge Prism Dykeman 1977; KCDNR 2000). Observations of bull trout in the Ballard Locks and cursory hydroacoustic tagging suggest that these fish may be migrating to the Lake Washington area from other watersheds such as the Stillaguamish or Snohomish systems (Goetz et al. 2004). Bull trout have been caught in Shilshole Bay and the Ballard Locks during late spring and early summer in recent times. In 2000, eight adult and subadult fish (mean size 370 millimeters; 14.5 inches) were caught in Shilshole Bay below the locks between May and July. These fish were found preying upon juvenile salmon (40 percent of diet) and marine forage fish (60 percent of diet) (Footen 2000, 2003). In 2001, five adult bull trout were captured in areas within the Ballard Locks and immediately below the locks. One bull trout was captured in the large lock in June, and in May one adult was captured while migrating upstream through the fish ladder in the adult steel head trap. Three adult bull trout were also captured below the tailrace during the peak of juvenile salmon migration on June 18 (Goetz et al. 2004). Coho Salmon Status ofthe ESU The Puget Sound/Strait of Georgia coho salmon ESU includes populations from drainages of Puget Sound and Hood Canal, the Olympic Peninsula east of Salt Creek, and the Strait of Georgia from the east side of Vancouver Island (north to and including Campbell River) and the British Columbia mainland (north to and including Powell River), excluding the upper Fraser River above Hope. WDF et al. (1993) identified 40 coho populations within the boundaries of the Puget Sound/Strait of Georgia ESU. While most were sustained by natural production, only three of these populations were determined to be of native origin. Weitkamp et al. (1995) noted that while coho salmon within the Puget Sound ESU were abundant, and with some exceptions run sizes and natural spawning escapements generally stable, there are substantial risks to whatever native production remains. The Puget Sound coho ESU remains a candidate for listing under the federal Endangered Species Act. From 1991 through 2000, the annual run size of coho populations entering Puget Sound was 669,000, of which 44 percent were derived from natural spawning. Over this same period, wild coho escapement increased, which is primarily attributed to a reduction in Puget Sound fisheries, allowing more fish to reach spawning grounds even though total run sizes decreased. High harvest rates and a recent decline in average size of spawners is a concern because of the potential for reduced fecundity and/or productivity (Weitkamp et al. 1995). Hatchery coho programs are also intensive in Puget Sound, influencing population trends. From 1991 through 2000, an average of approximately 24 million hatchery- produced juvenile coho were released into Puget Sound annually. Over this period, total hatchery releases decreased from about 40 million in 1991 to less than 10 million in 2000 (PSMFC 2002). Life History and Habitat Requirements The coho salmon life history roughly consists of 18 months of freshwater rearing followed by 18 months of ocean rearing (Weitkamp et al. 1995). Coho salmon typically spawn in relatively shallow tributary streams from October through February. Spawning generally occurs in temperatures ranging from 42 to 49T Coho salmon spawning gravel ranges from 0.5 to 4 inches (Reiser and Bjornn 1979). Fry emerge in the spring and occupy most stream habitats, but are usually associated with the channel margin. Coho salmon fry densities are greatest in backwater pools, beaver dam pools, and off-channel areas (WDW 1991). Biological Assessment Page 20 Q \Projects\Barbee BA 2012\2012 Draft BA\2012 BA 082712_docx Cugini Property Boathouse Expanded Dredge Prism At least one year of freshwater residence is normal for coho salmon juveniles (USFWS 1986a), Coho salmon parr are frequently associated with side channels, wetlands, and off-channel sloughs for rearing (Sandercock 1991), Other important juvenile habitats include large wood accumulations, undercut banks, and complex pool habitats, Coho salmon juveniles are generally absent in channels lacking cover. Mason and Chapman (1965) reported that coho salmon juveniles are aggressive and territorial soon after emergence, and establish intraspecific dominance hierarchies, Where coho and Chinook salmon juveniles occurred together in streams, the coho were socially dominant, defending optimum feeding territory (Stein et ai, 1972). Water temperatures that average between 50 to 59'F in the summer are considered optimum for juvenile coho salmon rearing (USFWS 1986a). Bell (1973) reported the upper lethal limit to be 78.5'F, Out-migration of smolts to marine areas usually occurs from April to August of the year following their hatching, with peak migrations in May in nearly all areas (USFWS 1986a). Factors of Decline Risk factors associated with Puget Sound coho salmon stocks include high harvest rates, widespread habitat degradation, hatchery practices, and unfavorable ocean conditions. The genetic fitness of Puget Sound coho salmon stocks has been affected by widespread artificial propagation that includes inter-basin transfers of brood stock, and by hatchery fish escapement and introgression with wild populations (Weitcamp et al. 1995). Current and future population pressures on coho salmon in Puget Sound and Lake Washington are the same as those listed for Chinook. Local Stock Information Coho runs in Lake Washington are heavily influenced by hatchery production; therefore, recent studies have not been able to fully evaluate the status of self-sustaining naturally spawning coho populations in the region. Trends in both hatchery and wild escapements in Lake Washington are showing a decline that may be attributable to urbanization, high harvest rates, habitat degradation, and poor ocean conditions (Fresh 1994; WDF et al. 1993). Naturally spawning coho escapement (which could be a mix of native and hatchery origin coho) in Lake Washington was as high as 30,000 fish in 1970 and declined to less than 2,000 in 1992 (Fresh 1994). Index escapement values for Cedar River coho in the 1990s have declined to levels far below those observed in the 1980s, so the stock is now rated depressed by WDFW due to both the long-term negative trend in the index values and the chronically low nature of the indicator values. The Lake Washington/Sammamish tributaries coho stock is also rated as depressed by WDFW for the same factors (WDFW 2002). Available spawning survey information for May Creek suggests the same negative trend. Spawning surveys conducted in 1976, 1977, and 1985 found peak coho adult spawner densities in lower May Creek at 23, 5, and 55 coho per mile, respectively, while surveys in 1992 and 1993 found peak densities of only 2 fish per mile (Foster Wheeler 1995). Biological Assessment Page 21 QWrojccts\Barbee BA 2012\2012 Oraft HA\2012 HA OR2712_docx Cugini Property Boathouse Expanded Dredge Prism IV. ENVIRONMENTAL BASELINE The environmental baseline includes the past and present impacts of all federal, state, or private actions and other human activities in the action area, the anticipated impacts of all proposed federal projects in the action area that have already undergone formal or early section 7 consultation, and the impact of state or private actions which are contemporaneous with the consultation in process 50 CFR § 402.02(d). The baseline provides a reference for NOAA Fisheries and the USFWS to evaluate the species' current status in relationship to the proposed action. A. DESCRIPTION OF THE ACTION AREA AND PROJECT AREA The action area for the proposed project encompasses the southern portion of the May Creek Delta (southern Lake Washington) (Figure 2). The environmental baseline of the action area is generally described below, including the Lake Washington basin, May Creek watershed, and the project area. Action Area (May Creek and Lake Washington) May Creek May Creek drains approximately 14 square miles between the Coal Creek and Cedar River basins. The basin contains approximately 26 miles of mapped streams, two small lakes, and over 400 acres of wetlands (Foster Wheeler 1998). The mouth of May Creek is located on Lake Washington approximately two miles north of the Cedar River in Renton, Washington. Historically, the May Creek watershed was forested with predominantly coniferous stands. Over recent decades, land uses in the western one-third of the basin have changed to intensive residential development, with some industrial development in the lowermost reaches, including the Barbee Lumber Mill. The eastern two-thirds of the watershed retains a mix of rural residential, small farms, and some forested areas (King County 2001). Developed communities in the watershed include Renton, Newcastle, and around Lake Boren, Honey Creek, and Lake Kathleen (Foster Wheeler 1998). The Urban Growth Boundary (UGB), established in accordance with the Washington State Growth Management Act (GMA), bisects the May Creek basin, which limits urban-scale development from encroaching on the headwaters of the basin. Land development in the lower basin has substantially reduced forest cover, increased impervious surfaces, and filled wetlands. Currently, the amount of effective impervious surface coverage basin-wide is approximately 7 percent. In addition, under current zoning, full build-out would result in approximately 12 percent of the May Creek basin being covered in impervious surfaces (King County 2001). This is significant, as basin-wide impervious surface areas of 10 percent or greater have been found to have significant impacts on the health of aquatic ecosystems (May et al. 1997; Booth and Reinelt 1993; Karr 1991). Logging, coal mining, and agricultural activities have resulted in channelized streams, floodplain encroachment, and eroding slopes in the May Creek watershed. The lower four miles of May Creek are within an urbanized area. This portion of the creek experiences high sediment loading and lacks current and future sources of LWD (Foster Wheeler 1998). The lack of LWD has resulted in loss of habitat complexity, specifically pool habitat. Biological Assessment Page 22 Q:\Proje\:ls\8arbee BA 20!2l2012 Draft HA\2012 BA 082712.docx Cugini Property Boathouse Expanded Dredge Prism Sediment deposition in lower May Creek has increased due to forest removal, the presence of rock quarries, and the expansion of road networks. Vegetation removal throughout the basin has resulted in higher maximum flows and lower minimum flows. Higher flows than what naturally occurred can result in stream substrate scour, which may negatively impact salmon redds (Foster Wheeler 1998). The increase in flood flows has resulted in additional erosion of hillsides, flooding and sediment deposition in May Valley, erosion in the canyon downstream of the valley, and flooding and sediment deposition near the mouth of May Creek (King County 2001). Peak flows have increased moderately in May Valley, on the order of 15 to 20 percent greater than the predevelopment conditions for the 2-, 25-, and 100-year return intervals (King County 2001). From approximately RM 3.9 to 7.0, the riparian area of May Creek is heavily impacted by grazing (Foster Wheeler 1998). Agricultural activities in May Valley have drained historic wetlands and channelized May Creek (Buchanan 2003). The South Fork of May Creek starts at RM 7.0. Portions of the South Fork go dry in the summer from RM 7.0 to 9.1. A 128-foot-long culvert blocks anadromous fish passage at RM 7.7. The North Fork of May Creek parallels State Route (SR) 900, resulting in degraded riparian conditions and channelization. Three quarries along the North Fork contribute to high sediment loading in the system (Foster Wheeler 1998). The East Fork of May Creek flows into the South Fork at RM 7.2. Habitat conditions in the East Fork are highly degraded due to the presence of man-made berms, culverts, and man-made ponds (Foster Wheeler 1998). Almost all of the basin's nearly 80 identified wetlands have been disturbed by deforestation, filling, draining, agricultural practices, or buffer removal, with much of this disturbance occurring since the wetlands were first inventoried in 1983 (King County 2001). The May Creek Basin Action Plan (King County 2001) includes several goals, one of which is to protect and enhance fish and wildlife habitat and water quality in the basin. Implementation of habitat restoration actions under the Basin Plan is dependent on funding availability. Restoration work along May Creek has recently taken place; the Barbee Mill Company has substantially improved the vegetated cover in the May Creek riparian area upstream from the lowermost bridge to Lake Washington Boulevard by planting willows, cottonwoods, grasses, and other native vegetation. In this area (located upstream from the proposed dredging area). the vegetated stream buffer ranges in width from 5 to over 100 feet in width. Despite the current habitat conditions, the lower reaches of May Creek experience the heaviest use by fish (Foster Wheeler 1998). Steelhead, cutthroat trout, Chinook, coho, and sockeye salmon spawn in May Creek. Spawning gravel, although embedded, likely supports successful incubation (Buchanan 2003). The primary limiting factor for Chinook and sockeye in May Creek likely is available spawning area and incubation success (Foster Wheeler 1998). The primary limiting factor for coho, steel head, and cutthroat in May Creek likely is the availability of high quality rearing and over-wintering habitat (Foster Wheeler 1998). Lake Washington Lake Washington is the second largest natural lake in the state of Washington with 80 miles of shoreline, including about 30 miles along the shore of Mercer island (Shared Strategy, 2007). Over 82 percent of the Lake Washington shoreline is armored and is shaded by more than 2,700 piers and docks (Shared Strategy, 2007). Regulated lake levels and extensive armoring have hampered sediment transport and sandy beaches need to be augmented by periodic sediment supplies. Additional factors affecting the habitat features in the Lake Washington basin include a lack of riparian vegetation due to clearing and development; loss of channel and shoreline complexity Biological Assessment Page 23 Q:\Projccts\Rarbcc HA 2012\2012 Draft BA\20 12 DA 082712.docx Cugini Property Boathouse Expanded Dredge Prism including a lack of woody debris and pools; the development of fish passage barriers with the construction of road crossings, weirs, and dams; and degraded water and sediment quality caused by increases in pollutants and high temperatures (Shared Strategy, 2007). The Lake Washington/Lake Sammamish area includes two major rivers systems, the Cedar and Sammamish, and three large lakes (Lake Union, Lake Washington, and Lake Sammamish). It also includes numerous smaller streams such as Bear, North, and Swamp creeks that drain into the system from the north. Historically, Lake Washington had a vegetated shoreline of wetlands, trees, brush, and other mixed vegetation that created a diverse nearshore habitat for juvenile salmonids. The shoreline's natural structural complexity was beneficial for fish and other aquatic species. Larger conifers that grew in the riparian area provided shade and contributed plant material (branches, needles) and terrestrial insects to the aquatic food chain. The United States Fish Commission Bulletin published in 1898 describes the lake as follows; "Only in a few places along the shore of the entire lake is the bottom sufficiently free from snags, fallen trees, and other material to permit the successful hauling of nets", In the past 150 years, the Lake Washington/Lake Sammamish watershed has been dramatically altered from its historical condition. Habitat degradation started with heavy logging of old growth forest throughout much of the watershed in the late 19th century. In 1901, the City of Seattle began diverting water out of the upper Cedar River to serve as its main water supply. Between 1910 through 1920, the natural Lake Washington outlet was redirected from the Black River to the Lake Washington Ship Canal and Hiram M. Chittenden Locks, which were excavated to connect Lake Washington to Lake Union and then to Puget Sound. Previously Lake Union was a freshwater lake that was not connected to Lake Washington and had no outlet to Puget Sound. The redirection of the Lake Washington outlet ultimately resulted in the lowering of the lake level by about 9 to 10 feet and the loss of over ten miles of shoreline and approximately 1,000 acres of wetlands. Shallow lake margins and wetlands are generally considered to be high quality and preferred habitats for juvenile salmonids such as Chinook and coho salmon. During that same decade, the Cedar River was redirected from the Black River into the south end of Lake Washington. In the ensuing years, the most important cause of physical change to the watershed area has been the expansion of urban and suburban development. In the upper Cedar River, land is devoted almost entirely to preservation of forests. Residential, industrial, and commercial uses prevail in the lower reaches of virtually all the streams. Today, approximately eighty percent of the existing shoreline is lined with bulkheads that reduce the remaining shallow water habitat and change shallow water substrates. Over 2,700 piers extend into the lake, introducing a different pattern of shade from that produced by shoreline vegetation and changing the underwater habitat from complex (horizontal fallen trees with branches) to simple (vertical smooth pilings). Piers are also used heavily as ambush cover by non-native species such as bass, which may prey heavily on native juvenile salmon ids. The result of these actions is to remove the complex and diverse plant community and associated food web from the shallow water habitat. The current lake level is artificially regulated within a two-foot range. The high water/low water regime is reversed from the natural state. High water occurs during the summer for extensive operation of the Ballard Locks. Low water occurs during the winter protect property from winter wave action.

The three watersheds in the basin with the largest sa[monid populations, the Cedar River, and Bear and Issaquah creeks, support Chinook, sockeye, coho, kokanee, steelhead, rainbow and coastal cutthroat trout as well as native char. Some of the small independent Puget Sound tributaries also support chum, coho, and cutthroat. Maps illustrating known and presumed distributions for each of these species are avai[able in Kerwin (2001). Additionally, at least 40 non- native fish species (of which approximately 24 persist) have been introduced into the Lake Washington basin, most notably smallmouth and largemouth bass, creating numerous trophic interactions with native species, most notably predation on native sa[monids. Sockeye salmon in the lake system are believed to be primarily the descendants of fry transplanted from Baker Lake in the 1930s. While many species have been introduced, native species such as Cedar River pink and chum salmon have been extirpated. Project Area On May 3 and May 17, 2012, Meridian Environmental fisheries biologists completed detailed aquatic habitat and fish presence surveys in the area of Lake Washington located immediately south of the May Creek delta. The objective of these surveys was to document the existing aquatic habitat conditions; determine the species composition and average densities of aquatic macrophytes; and describe the distribution and relative abundance of fish species observed during the survey. An additional objective was to compare the results of 2005 surveys with the results offish habitat and fish population surveys completed within and near the project area in 1993, 2000, 2001, and 2005 (Harza 1993; Harza 2000; Meridian Environmental, Inc. and Harza 2001, Meridian Environmenta[ Inc. 2005). It should be noted that the timing of the 2012 surveys was designed to coincide with the expected residence period of juvenile coho, stee[head, and Chinook. Survey Methods Eight underwater (SCUBA) transects were placed between the south end of the May Creek delta and the existing dock and log boom located at the south end ofthe proposed project area (Figure 3). Transects ranged from 75 to 250 feet in length, and extended approximately 480 feet into Lake Washington. Transects 1, 2 and 8 were shallow-water snorkel survey transects located along the north and southeast shoreline. Transects 4, 5, and 6 paral[eled each other, oriented from roughly 20· to 200·, and transect 3 extended from an area located just southeast of the osprey nesting platform to the end of the log boom (Figure 3).

As in past surveys, American waterweed was the dominant aquatic plant species both in distribution and abundance throughout the proposed project area. Figure 10. Curly-Ieafpondweed photographed along transect 6 (2012 SCUBA survey). Shoreline Condition As discussed previously, the littoral zone and shore lin e of Lake Washington has been extensively modified in the past 150 years due to the change in lake leve l; construct ion o f piers. docks, and bulkheads; removal of LWO ; and the expans ion of Eurasian watermilfoil and other non -native aquatic macrophytes (Fresh and Lu cchetti 2000). Riparian habit at, once dominated by hardstem bulrush and willow, has been repla ced by developed and hardened shorelines with la ndscaped ya rd s. According to Toft (2001), an estimated 71 percent of the Lake Washington shoreline is armored with riprap or bulkheads and approximately 2,737 residential piers have been built. This lo ss of natural sh oreline ha s reduced the occurrence of complex shoreline habitat features such as overhanging and emergent vegetation, woody debris (especially fallen trees with branches and/or rootwads intact). and gravel/cobble beaches, which in turn has reduced the ava ilability of refuge habitat and forage for juvenile salmon id s. Like most of the shorel in e along Lake Washington, the shore line in the proposed project area is armored with riprap; however, emergent vegetation (soft rush, grasses , sedges, etc.) was observed growing along transect 1, with a substantial increase in the amount of vegetatio n observed in 2012. In 2005 and 2012, juvenile rainbow trout, cutthroat trout, coho salmon, sculpin, and sticklebacks were observed using this using this emergent vegetat ion as cover.

Silt and sand are the dominant substrates and the western portion of the expanded dredge area appears to be continually impacted by large amounts of sediment (primarily sand) entering the lake from May Creek. The dock, boathouse dock, and culvert located to the northeast of the project provide overhead cover for juvenile salmonids at depths less than approximately 2 feet (Figure 15). At depths greater than 2 feet. these structures also appeared to provide cover for juvenile smallmouth bass; however, no adult large or smallmouth bass were observed near the boathouse dock or under the dock located to the south of the dredging area in 2012. The riprap surrounding the May Creek delta and southeastern shoreline also limits the amount of shallow-water refuge habitat for juvenile salmon ids and other fi sh specie s by preventing the establishment of shoreline vegetation cover. However, the large interstitial spaces found within the riprap shoreline did appear to provide ambush habitat for native cottids (also known to prey on juvenile salmonids). In summary , aquatic habitat conditions have greatly improved within and near the May Creek delta in the past 5 years. However, juvenile salmonid rearing habitat conditions in the proposed expanded dredging area are still considered poor due to the lack of shallow water structure such as large and small woody debriS and brush.

DESCRIPTION OF THE ENVIRONMENTAL BASELINE Environmental Baseline Matrix For proposed actions that affect freshwater habitat, the Services u sually define the biological requirements for listed species in terms of a concept called properly functioning condition (PFC). PFC is the sustained presence of natural habitat-forming processes in a watershed (e .g., riparian community succe ss ion. bedload transport. preCipitation runoff pattern, channel migration) that are necessary for the long -term survival of the species through the full range of environmental variation. PFC, then, constitutes the habitat component of a specie s' biological requirement s. The indicators of PFC vary between different landscapes based on unique phy siographi c and geologic feature s. For ex ample , aquatic habitats on timberlands in glacial mountain valley s are controlled by natural processes operating at different scales and rate s than are habitats on low-elevation coastal rivers or lake systems. In the NMFS PFC framework, baseline environmental conditions are described as "properly functioning" (PFC), "at risk" (AR). or "not properly functioning" (NPF ). USFWS also has a PFC framework that define s ba seline environmental conditions in terms of "functioning appropriately" (FA), "functioning at risk " (AR), or "fun ctioning at una cceptable ri sk" (UR ). The PFC concept includes a recognition that natural pattern s of habitat di sturbance will continue to occur. For example , floods, landslides, wind damage, and wildfires result in spatial and temporal variabilit y in habitat characteristics , as would anthropogenic perturbations.

Such considerations may include, for example, the species' status, the condition ofthe environmental baseline, the particular reasons for listing the species, any new threats that have arisen since listing, and the quality ofthe available information. In this section of the BA, we summarize existing environmental conditions and parameters for the action area and present the status of each indicator as PFC, AR, or NPF following the NMFS and USFWS "pathways and indicators" matrices (Table 6). For the purposes ofthis analysis we have integrated the NMFS and USFWS matrices in order to facilitate an analysis of the effects of the proposed project on bull trout, steelhead, and Chinook salmon simultaneously. For consistency we have used the terms PFC, AR, or NPF (NMFS terminology) for rating specific environmental indicators applicable to bull trout from the USFWS (1998) matrix. For practical purposes, PFC, AR, or NPF (NMFS terminology) are equivalent to FA, AR, and UR (USFWS terminology). Criteria for PFC, AR and NPF are described in detail in NMFS (1996) and USFWS (1998), but summarized for each indicator following Table 4 along with justification for the status of each indicator in the action area. The effects that the proposed project may have on each environmental indicator are analyzed subsequently in Section V. It is important to note that the current status of a particular environmental indicator may not be related to a proposed project. For example, road density in the Lake Washington basin may rate as "not properly functioning" under existing conditions even though the proposed project has no influence on this indicator. In addition, the 1996 NMFS matrix was originally designed by the u.s. Forest Service to evaluate timber harvest activities on rangeland watersheds. Therefore, not all of the parameters below are necessarily applicable to the small spatial scale of the proposed project, although it is still a useful tool in characterizing the baseline conditions, which can be used to assess potential effects of the proposed project.

AR conditions range from 57 to 60'F for spawning and from 57 to 64 'for migration and rearing. NPF is defined as greater than 60'F for spawning and greater than 64'F for rearing. USFWS (1998) defines PFC for bull trout as water temperatures ranging from 35.6 to 41 'F for incubation, 39.2 to 53.6'F for rearing, and 39.2 to 48.2'F for spawning. NPF is defined as temperatures outside the above criteria, with rearing areas and migration corridor temperatures over 59'F. Water temperatures in the area (East Mercer Channel) are generally below 50'F during the winter and between 62 and 75'F during the summer at depths of 3.3 feet. At a depth of 33 feet, water temperatures are about 45'F in the winter and between 59' and 68'F during the summer (http://dnr.metrokc.gov/wlr/waterres/lakes/site0840.htm). Under the USFW5 (1998) criteria these values would rate as NPF for bull trout spawning and incubation and summer migration corridors. Under the NMF5 (1996) criteria, these values would rate between NPF and AR for Chinook and steelhead spawning, rearing and migration. Biological Assessment Page 42 Q:\Prujects\Burbee BA 2012\2012 Drafl BA\2012 BA 082712.docx Cugini Property Boathouse Expanded Dredge Prism Sediment/Turbidity NMFS (1996) and USFWS (1998) define PFC as containing less than 12 percent fines in gravel, and NPF is defined as having greater than 17 percent surface fines (greater than 20 percent surface fines under USFWS 1998). The surficial substrate in the proposed expanded dredging zone is comprised of silt and sand. This condition is likely caused by the increased erosion and sedimentation deposition occurring in May Creek and in the May Creek delta. According to King County (2001), sediment deposition has occurred from natural erosion but has been accelerated by increased storm water runoff from upstream development and changes in the watershed land cover. Based on the documentation of increased erosion and sedimentation, this indicator is likely NPF. Chemical Contamination/Nutrients NMFS (1996) and USFWS (1998) define PFC as characterized by low levels of contamination with no 303(d) designated reaches, and NPF is defined as high levels of chemical contamination and nutrients and more than one 303(d) listed reach. lake Washington is a 303(d) water body for fecal coliform concentrations. In addition, Ecology has given several public warnings regarding lake Washington fish consumption due to high levels of mercury contamination (Ecology 2004). Based on known water quality degradation in lake Washington, this indicator rates as NPF. Physical Barriers NMFS (1996) and USFWS (1998) define PFC as man-made barriers that allow upstream and downstream passage at all flows without significant levels of mortality or delay, and NPF as man- made barriers that do not allow upstream and downstream fish passage at a range of flows. The fish passage facilities at the Ballard locks provide adult access to lake Washington and smolt passage to the Puget Sound; however, the locks are a predation bottleneck. Heavy seal predation on adult salmon at the locks is a common and recurring problem. In addition, the sharp demarcation between the fresh and saltwater environments at the lake Washington outlet is likely a stressor for juvenile salmonid out-migrants. Therefore, the "Physical Barriers" indicator should be considered AR. Substrate NMFS (1996) and USFWS (1998) define PFC as reach embeddedness of less than 20 percent and NPF as embedded ness greater than 30 percent. The substrate in the project area is comprised of sand and silt, based on the results of multiple SCUBA surveys. According to King County (2001) fine sediment deposition in lower May Creek is an ongoing problem. This fine sediment is transported immediately to the south to the boathouse area by wave action. Based on chronic fine sediment deposition in lower May Creek and the boathouse area, this indicator rates as NPF. Biological Assessment Page 43 Q.\ProjectsI.Oarbee BA 2012\2012 Draft BA\2012 BA 082712,docx Cugini Property Boathouse Expanded Dredge Prism Large Woody Debris NMFS (1996) and USFWS (1998) define PFC as greater than 80 pieces of wood per mile, which are greater than 24 inches in diameter and greater than 50 feet long. NPF is defined as wood that does not meet the criteria of PFC and sources of LWD recruitment are lacking. This indicator does not apply to the proposed action. Off-channel Habitat NMFS (1996) and USFWS (1998) define PFC for off-channel habitat as many backwaters with cover and low energy, off-channel areas, including ponds and oxbows. NPF is defined as a watershed with few or none of these habitat types. Lowering of Lake Washington in the early 1900s resulted in the loss of over 10 miles of shoreline and approximately 1,000 acres of wetlands. Shallow lake margins and wetlands are generally considered to be high-quality and preferred habitats for juvenile salmon ids such as Chinook and coho salmon. Based on loss of wetlands, this indicator rates as NPF. Refugia NMFS (1996) defines PFC for refugia as habitats that are adequately buffered by intact riparian reserves of sufficient size, number and connectivity to maintain viable populations and subpopulations. NPF is defined as no adequate habitat refugia. USFWS (1998) defines PFC for refugia as habitats capable of supporting strong and significant populations of bull trout that are protected, well distributed, and connected for all life stages and forms. NPF is defined as the absence of habitat refugia. The action area has been extensively altered over the past 100 years by human development and the Lake Washington/Cedar/Sammamish watershed is likely one of the most highly disturbed urban watersheds in the state. Although adequate bull trout habitat exists in the upper Cedar River, no bull trout refugia exists in the action area due to high summer water temperatures. The action area also lacks adequate local refugia for Chinook and steelhead due to extensive riparian, instream, and shoreline habitat alterations. Therefore, this indicator rates as NPF. Streambank Condition NMFS (1996) defines PFC as greater than 90 percent (80 percent under USFWS criteria) of any stream reach of which 90 percent or more is stable NPF is defined as less than 80 percent stability. The USFWS (1998) defines NPF as less than 50 percent of any stream reach that is characterized as at least 90 percent stable. The shoreline along the action area is developed and bulkheaded. The banks are not actively eroding, but the bulkheads have disrupted natural shoreline processes. In addition, over 2,700 piers extend into Lake washington. Lowering of the lake in the early 1900s substantially altered the Lake Washington shoreline, resulting in the loss of approximately 10 miles of lake shore perimeter. Due to extensive alteration of the Lake Washington shoreline, this indicator rates as NPF. However, stream bank condition adjacent to the proposed project site has improved substantially in the past 5 years. Biological Assessment Page 44 Q.\Projects\Harbee HA 2012\2012 Draft BA\20 12 BA 082712 don Cugini Property Boathouse Expanded Dredge Prism Floodplain Connectivity NMFS (1996) and USFWS (1998) define PFC as well-connected, off-channel areas with overbank flows of sufficient frequency to maintain function. NPF is defined as a severe reduction in hydrologic connection with off-channel habitats. Lake Washington has been lowered, disconnecting the mouths of streams from their floodplains. Therefore this indicator rates as NPF. Road Density and Location NMFS (1996) and USFWS (1998) define PFC as less than 1 mile of road per square mile with no valley bottom roads and NPF as greater than 2.4 miles of road per square mile with many valley bottom roads. The action area has been heavily urbanized and has a well-developed road network. Road densities, although not estimated for this analysis, likely rate as NPF. Disturbance History NMFS (1996) and USFWS (1998) define PFC as having less than 15 percent equivalent clear-cut area (entire watershed) with no concentration of disturbance in unstable or potentially unstable areas, and/or refugia, and/or riparian area; and for Northwest Forest Plan area (except adaptive management areas), 15 percent retention of late successional old growth timber in the watershed. The "Disturbance History" indicator rates as NPF based on extensive historic and ongoing development. Riparian Reserves NMFS (1996) and USFWS (1998) define PFC as a riparian reserve system that provides adequate shade, LWD recruitment, habitat protection, and connectivity to all sub-watersheds. This reserve must be greater than 80 percent intact and the vegetation must be greater than 50 percent similar to the potential natural community composition. Riparian habitat in the action area along Lake Washington has been highly altered and extensively cleared, primarily for residential development. This indicator rates as NPF. Population Size USFWS (1998) defines FA as the mean subpopulation size or a local habitat capacity of more than several thousand individuals and all life stages evenly represented in the subpopulation. AR is defined as fewer than 500 adults in a subpopulation, but more than 50. The Lake Chester Morse bull trout population in the upper Cedar River would be classified as FA under the USFWS criteria; however, this is a naturally resident population located upstream of a passage barrier. In addition, the Cedar River historically was not connected to Lake Washington. There are no known current or historic (but now extinct) bull trout populations located within the Lake Washington basin, except for the Chester Morse population. However, it appears that individuals from the Chester Morse population may pass downstream into Lake Washington and Biological Assessment Page 45 Q:\Projects\Barbee BA 20 12\20 12 Draft BA\20 12 HA 082712 docx Cugini Property Boathouse Expanded Dredge Prism that anadromous bull trout migrate to the Lake Washington vicinity from other basins such as the Stillaguamish, Snohomish, and possibly the Skagit River basins. Bull trout typically exhibit a patchy distribution, even in pristine watersheds. There is no indication that a bull trout population historically would have occupied May Creek. Generally, self-sustaining local bull trout subpopulations are only found in watersheds that have accessible stream habitat above the average winter snow line (where winter snowpack accumulates) which is approximately 900 feet in western Washington (USFWS 2004). The May Creek watershed headwaters only extend to an elevation of approximately 500 feet, with no areas of winter snowpack accumulation. Bull trout spawning in May Creek would not be expected currently or historically because the water temperature regime is likely too warm due to the low elevation and lack of substantial cold springs, glaciers, or winter snowpack. As there is no current or historic local self-sustaining bull trout population or subpopulation indigenous to the action area, this indicator is not applicable. Growth and Survival USFWS (1998) defines FA as a subpopulation with the resilience to recover from short-term disturbances in 5 to 10 years. Additionally, the subpopulation is increasing or stable, with at least 10 years of data to support such a trend. As discussed above, there is no known current or historic bull trout subpopulation indigenous to the action area, therefore this indicator is not applicable. Life History Diversity and Isolation USFWS (1998) defines FA as presence of the migratory form with subpopulations in close proximity to other spawning and rearing groups. There is high likelihood of neighboring subpopulations straying and adults mixing with other groups. UR is defined as an absence of the migratory form and the subpopulation is isolated to a local stream and unlikely to support more than 2,000 fish. As discussed above, there is no known current or historic bull trout subpopulation indigenous to the action area; therefore, this indicator is not applicable. While this indicator is meant to apply to local subpopulations within an action area, there may be migratory bull trout straying from other basins, such as the Snohomish and Stillaguamish River basins or the upper Cedar River. Persistence and Genetic Integrity USFWS (1998) defines FA as possessing high connectivity among more than five subpopulations with at least several thousand fish each. UR is defined as having little or no connectivity and subpopulations that are in low numbers or in decline. As discussed above, there is no known current or historic bull trout subpopulation indigenous to the action area; therefore, this indicator is not applicable. v. EFFECTS OF THE ACTION ON FISH SPECIES "Effects of the action" means the direct and indirect effects of an action on the listed species or critical habitat, together with the effects of other activities that are interrelated or interdependent with that action, that would be added to the environmental baseline (50 CFR 402.02). Effects of the Biological Assessment Page 46 Q \ProJecls\Barbee BA 2012\2012 Draft 8A\20 12 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism action that reduce the ability of a listed species to meet its biological requirements may increase the likelihood that the proposed action would result in jeopardy to that listed species or in destruction or adverse modification of a designated critical habitat, The proposed action may affect Chinook, steelhead, and bull trout by causing physical changes to the environmental baseline and through indirect effects to the species. These effects may impact migrating and rearing juvenile Chinook and steel head within the action area, The major concern of the proposed action is the alteration of Chinook and bull trout critical habitat caused by dredging in the proposed expanded dredging prism (Appendix A), A. DIRECT EFFECTS In this section we analyze the direct effects of the proposed project on three primary elements that may be influenced by the action, These elements are direct effects on individual fish, such as harassment or actual mortality through contact with the dredging equipment, pile removal, and root wad placement; direct effects on habitat by physically disturbing the substrate and removing sediments from the proposed expanded dredging area; and direct effects on water quality during dredging and fish rock placement. Direct Effects on Fish Take of bull trout in the nearshore area of Lake Washington during the summer is extremely unlikely, Water quality monitoring in 2002 (within the silt curtain of the dredging zone and immediately outside the silt curtain) strongly suggest that water temperatures during July and August (proposed dredge timing) exceed the generally reported upper limit of bull trout temperature tolerance of approximately 59°F, Temperatures in the dredging zone (within the silt curtain) from July to late September 2002 exceeded 65°F and averaged 69.4°F, Due to probable high water temperatures outside the species tolerance range in the dredging zone during summer, it would be extremely unlikely for bull trout to be present in the dredging area and, therefore, take of individual bull trout is not expected. Adult Chinook typically migrate into Lake Washington at the Ballard Locks in mid-June, peaking in late August (Kerwin 2001), Spawning typically occurs from mid-September through November (Kerwin 2001), Juvenile Chinook rearing occurs from approximately January through June (Kerwin 2001). Most juvenile Chinook move through the Ballard Locks by the end of June, although the entire out-migration period is unknown (Kerwin 2001), Limiting in-water work to the NMFS approved July 16 -September 15 work window would minimize the potential to adversely affect juvenile Chinook, as the vast majority of juveniles in Lake Washington are expected to migrate prior to July. Because the proposed in-water work window would overlap with the adult Chinook migration period, there is some chance that adult Chinook salmon may be present in the dredging zone and may be temporarily harassed and displaced by dredging activities, However, it is anticipated that adult Chinook would avoid direct contact with the clamshell dredging eqUipment, and would not be physically injured or killed by the dredging activities, Short term increases in turbidity are not expected to adversely affect adult Chinook, Adult steel head spawn from mid-December through early June in the Lake Washington basin, Adults migrate to spawning grounds beginning in the fall. Adult steelhead do not necessarily die after spawning and post-spawn adults (kelts) migrate downstream back to saltwater after spawning. Biological Assessment Page 47 Q:\Projects\Barbee BA 2012\2012 Draft I:3A\2012 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism Therefore, adult steelhead could be present in Lake Washington from the fall through the early summer. Juveniles can spend several years in freshwater before migrating to saltwater and could be present in Lake Washington all year. Similar to Chinook, there is some chance that adult or juvenile steelhead may be present in the dredging zone and may be temporarily harassed and displaced by dredging activities. However, it is anticipated that adult and juvenile steel head would avoid direct contact with the clamshell dredging equipment, and would not be physically injured or killed by the dredging activities. Coho begin entering Lake Washington in late August and continue to enter the lake through early December. Most coho spawning occurs in November and December (Kerwin 2001). Juvenile coho typically rear for 12 to 14 months in freshwater. In Lake Washington, the peak of the outmigration occurs in early May (Kerwin 2001). Juvenile coho are present in the project area in the spring and adult coho are known to spawn in May Creek in the fall. The proposed dredging period, while optimally designed to avoid the presence of juvenile and adult anadromous salmon ids, does overlap with the coho rearing and out-migration time and adult coho migration. It is most likely that coho juveniles may be present during dredging and may be temporarily displaced, but as with Chinook and steelhead, it is not anticipated that coho would come into direct contact with dredging equipment and be physically injured or killed. Direct Effects on Habitat It is apparent from Tabor et al. (2004) that juvenile Chinook salmon in the south end of Lake Washington prefer shallow (1 to 2 feet in depth) stream delta habitat with sand and gravel substrates. Water depths in the proposed expanded dredging zone are generally deeper than those preferred by rearing juvenile Chinook. In addition, the aquatic habitat located immediately to the south of the May Creek delta and along the shoreline of the lake to the south is not heavily used by juvenile Chinook (Tabor et aI., 2004 and Table 4). Even though the proposed project would impact habitats that are not known to be preferred by juvenile Chinook, the project proponent would enhance the lakeshore margin with a "fish rock" gravel mix to create additional shallow water habitat, which Tabor et al. (2004) suggests might be preferred by rearing Chinook. Similar information regarding juvenile steel head and coho use of Lake Washington shoreline habitat is not available; however, many rainbow trout (same species as steel head) and coho were observed by Tabor et al. (2004) and during the SCUBA surveys conducted in 2005. Based on the recent SCUBA survey observations within and near the proposed project area, it appears that juvenile steel head and coho prefer the shallow water habitat located along the shoreline to the north and northeast of the proposed expanded dredging area, and are typically associated with overhanging brush and emergent vegetation. Juvenile coho were also abundant in the shallow water areas «3 feet deep) located along the northeastern corner of the boathouse dock. No steel head or coho were observed at depths greater than approximately 3 feet. Based on these findings, it appears that juvenile steelhead and coho habitat would not be directly affected by the proposed action. Due to the overall low numbers of bull trout, if any, and lack of information concerning their habitat use in Lake Washington, effects of dredging on bull trout habitat use is unknown, but is suspected to be negligible. The effect on forage species habitat is likewise unknown, but due to the relatively small area, the effect is suspected to be discountable. Biological Assessment Page 48 Q'IPro]ccts\Barbec AA 201212012 Oraft BA\2012 BA 082712.docx Cugini Property Boathouse Expanded Dredge Prism Direct Effects on Water Quality The proposed dredging project has the potential to increase turbidity (i.e., reduce water clarity) and increase total suspended solids (TSS) within and near the proposed action area. Turbidity and TSS levels have been reported to cause physiological stress, reduce growth, and adversely affect salmonid survival. The potential for adverse effects depends upon several factors, including the duration ofTSS increases, the area of the turbidity plume, the amount and velocity of ambient water (dilution factor), and the size of suspended sediments. In the case of the proposed project, increases in suspended sediments and turbidity would be localized at the point of dredging and increases would last for only short periods oftime, expected to be less than several hours. Evidence suggests that salmonids are well adapted to short term increases in turbidity, as such conditions are frequently experienced in natural settings as a result of storms, landslides, or other natural phenomena (Redding et al. 1987; NMFS 2003). It is chronic exposure to increased turbidity that has been found to be the most potentially damaging to salmonids (The Watershed Company et al. 2000). Studies have found that when habitat space is not limiting, salmonids will move to avoid localized areas of increased turbidity, thereby alleviating the potential for adverse physiological impacts (Bisson and Bilby 1982; NMFS 2003). Juvenile salmon have been shown to avoid areas of unacceptably high turbidity (Servizi and Martens 1991), although they may seek out areas of moderate turbidity (10 to 80 NTU), presumably as cover against predation (Cyrus and Blaber 1987a, 1987b). Studies have found that fish that inhabit waters with elevated TSS may experience a reduction in predation from piscivorous fish and birds (Gregory and Levings 1998). In such cases, salmonids may actually increase foraging activity, as they use turbid water as a sort of cover from predators (Gregory 1993). However, feeding efficiency of juveniles is impaired by turbidities in excess of 70 NTU, well below sublethal stress levels (Bisson and Bilby 1982). Reduced preference by adult salmon returning to spawn has been demonstrated where turbidities exceed 30 NTU (20 mg/L suspended sediments); however, Chinook salmon exposed to 650 mg/L of suspended volcanic ash were still able to find their natal streams (Whitman et al. 1982). The highest turbidity values recorded during recent dredging activity in 2002 were less than 7 NTU, and turbidity measured in the dredging zone was on average less than 1.4 NTU greater than turbidity outside the dredging zone (Table 5). Overall turbidity values of less than 7 NTU are very low, and the effect of slightly increasing turbidity by 1 or 2 NTU on listed fish species should be considered discountable. Washington state water quality regulations allow a short term increase of 10 NTU when background turbidity is less than 50 NTU (WAC 273-201A-030). Based on the 2002 monitoring results, future dredging would likely meet this standard. Based on these data and the scientific literature cited above, it is unlikely that the short-term (7 to 10 days every 3 to 5 years) and localized elevation of turbidity (less than 5 NTU elevation above background turbidity levels) generated by the proposed project would rise to the levels that would be expected to cause harm to Chinook, steel head, or bull trout that may be present in the dredging lone. Biological Assessment Page 49 Q:\Projects\Barbee BA 2012\2012 Draft BA\2012 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism Table 5. Turbidity monitoring during 2002 May Creek delta dredging (11 days of sampling over the dredging period). Within silt curtain Outside silt curtain (In dredge zone) (out of dredge zone) Minimum 1.1 NTU 1.1 NTU Average 2.1 NTU 1.4 NTU Maximum 5.2 NTU 3.1 NTU In-water work such as dredging also has the potential to degrade water quality though the spill of toxic substances, such as fuel or hydraulic fluid from dredging or pile placement equipment. This potential is best reduced by maintaining equipment in proper working condition and by maintaining a spill prevention control and countermeasure plan (SPCCP). Typically, a SPCCP would specify areas for equipment maintenance and refueling, spill prevention and emergency response strategies, requirements for keeping emergency response spill containment kits onsite, and for having trained personnel be onsite during in·water work. A SPCCP would be developed by the dredging contractor and approved by appropriate agencies, such as the WDOE, before dredging occurs. Preparation of a SPCCP would limit the potential for toxic material spills during dredging and pile replacement. B. INDIRECT EFFECTS Indirect effects aSSOCiated with the proposed project could affect the Chinook, bull trout, steelhead and coho prey base (e.g., aquatic macroinvertebrates and small forage fish). or through the creation of deep water habitat conditions that favor species known to prey on juvenile salmonids (i.e., large trout, bass, and sculpin). ESA-listed salmonids feed on certain macroinvertebrates, and therefore any loss of these prey items via dredging or disposal may harm these species. However, these effects would be localized to deepwater areas of low importance to these species. As a result, short-term impacts to macroinvertebrate abundance and diversity are likely to be limited. In addition, the continued growth of overhanging riparian vegetation along the delta (as a result of recent habitat enhancement) would likely increase the abundance and rate of terrestrial insects falling into the shallow margins of the lake to some degree, which would result in an increase in the juvenile salmonid prey base along the lake margin. C. EFFECTS FROM INTERDEPENDENT AND INTERRELATED ACTIONS No interdependent or interrelated actions have been identified in association with the proposed expanded dredging project. D. EFFECTS FROM ONGOING PROJECT ACTIVITIES These effects are the same as previously described under direct effects of dredging. The only ongoing portion of the proposed project would be the periodic dredging of the boathouse area to maintain navigational depths every 3 to 5 years. Biological Assessment Page 50 Q:\Projecis\Barbcc RA 2012\2012 Draft BA\20 12 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism E. DESCRIPTION OF How THE ENVIRONMENTAL BASELINE WOULD BE AFFECTED As discussed previously, the PFC framework for EsA consultation characterizes baseline environmental conditions as "properly functioning," "at risk," or "not properly functioning." If a proposed project is likely to impair properly functioning habitat, appreciably reduce the functioning of already impaired habitat, or retard the long-term progress of impaired habitat toward PFC, it is usually found likely to jeopardize the continued existence of the species, or adversely modify its critical habitat, or both, depending on the specific consideration of the analysis. Such considerations may include, for example, the species' status, the condition of the environmental baseline, the particular reasons for listing the species, any new threats that have arisen since listing, and the quality of available information. Actions that do not compromise a species' biological requirements to the degree that appreciably reduces the species' viability and chances of survival in the action area are considered not to reduce or retard. The project would provide an overall increase in water quality by removing the toxic creosote pilings, increasing primary productivity and the fish forage base within the lake by increasing light transmission, and increasing shallow water habitat along the shoreline. Therefore, the proposed project would result in an overall improvement to the aquatic habitat environmental baseline of Lake Washington. F. CUMULATIVE EFFECTS Cumulative effects are defined in 50 CFR § 402.02 as "those effects offuture State, tribal, local or private actions, not involving Federal activities, that are reasonably certain to occur in the action area." All areas within approximately 1 mile of the May Creek delta could be affected cumulatively by the proposed action. Potential cumulative effects may arise due to increased development in the action area. Expansion of the local economy and diversification would likely contribute to population growth. This growth is expected to increase demand for electricity, water, and buildable land in the action area which would, in turn, increase demand for transportation, communication and other social infrastructure. These actions would affect habitat features such as water quality and quantity which would directly affect the listed aquatic species. This is currently evidenced by the fact that runoff, erosion, and sedimentation has increased in May Creek as development has increased. It is expected that this trend would continue and be further exacerbated as additional development occurs and as impervious surfaces increase upstream in the watershed. As sediment deposition increases in the delta and sediment is transported to the boathouse area by wave action, more frequent dredging may be required to maintain navigational depths. G. TAKE ANALYSIS steelhead and Chinook would likely avoid the proposed expanded dredging zone; therefore, direct mortality of these species is not expected. The potential displacement of a few Chinook should not be considered harassment because the attributes of the proposed expanded zone are not considered preferred habitat for Chinook, based on recent SCUBA surveys and on the data presented in Tabor et al. (2004). Similarly, potential displacement of a few steelhead should not be considered harassment, as there appears to be ample nearby habitat of similar condition which any Biological Assessment Page 51 Q IProjects\Barbee BA 2012\2012 Omft HA120!2 AA 082712 docx Cugini Property Boathouse Expanded Dredge Prism displaced steelhead could occupy. Therefore, take of Chinook and steelhead should be considered discountable. Due to the overall lack of migratory bull trout within the Lake Washington basin, take of bull trout as a result of the proposed project is extremely unlikely. H. CRITICAL HABITAT EFFECTS ANALYSIS This critical habitat effects analysis determines whether the proposed project would destroy or adversely modify designated critical habitat for listed species by examining any change in the conservation value of the essential features of that critical habitat. This analysis relies on statutory provisions of the ESA, including those in Section 3 that define "critical habitat" and "conservation," those in Section 4 that describe the designation process, and those in Section 7 that set forth the substantive protections and procedural aspects of consultation; and on agency guidance for application of the "destruction or adverse modification" standard. With respect to designated critical habitat, the following analysis relies only on the statutory provisions of the ESA, and not on the regulatory definition of "destruction or adverse modification" at 50 CFR 402.02. The action area is designated critical habitat for Chinook. Juvenile Chinook may use the Lake Washington shore adjacent to the proposed expanded dredging area for foraging and rearing and adult Chinook may use the area as a migration corridor. The proposed project would have no influence on the ability of adult Chinook to migrate to spawning tributaries. Furthermore, current habitat conditions in the project area would not be considered optimal for juvenile Chinook rearing (Tabor et al. 2004). The proposed project would improve habitat conditions for rearing juvenile Chinook by creating additional shallow-water shoreline and instream habitat. Primary productivity and the fish forage base would be improved by allowing greater light penetration to the lakebed substrate by removing the three existing creosote pilings and replacing the floating platform with a more fish friendly float with grated decking. While the effects of this project may temporarily affect water quality through increased turbidity and reduce the fish forage base by removing lake sediments that contain benthic invertebrates, overall these attributes would be improved by increasing primary productivity as a result of increased light transmission, removing the toxic creosote pilings, and enhancing shallow-water habitats with gravel. Therefore, the proposed project would not result in long-term destruction or adverse modification of designated Chinook salmon critical habitat, but would result in a net improvement of critical habitat. Due to the very small project area and overall lack of migratory bull trout juveniles or adults within the Lake Washington basin, we conclude that bull trout critical habitat primary constituent elements would not be affected by the proposed project. Designated bull trout critical habitat would not be destroyed or adversely modified. Biological Assessment Page 52 Q'\Projects\Barbee SA 20!2\2012 Draft HA\2012 HA 082712 docx: Cugini Property Boathouse Expanded Dredge Prism VI. EFFECTS DETERMINATION FOR LISTED SPECIES AND DESIGNATED CRITICAL HABITAT The primary objective of this BA is to determine the effect the proposed project would have on ESA- listed Chinook salmon, steel head, and bull trout. This determination will be used by NMFS and USFWS to determine whether the proposed project is likely to jeopardize the continued existence of the listed species or to adversely modify their critical habitats (if applicable). To facilitate and standardize the determination of effects for ESA consultations, the Services use the following definitions for listed species (USFWS and NMFS 1998): No effect: This determination is only appropriate "ifthe proposed project will literally have no effect whatsoever on the species and/or critical habitat, not a small effect or an effect that is unlikely to occur." Furthermore, actions that result in a "beneficial effect" do not qualify as a no- effect determination. May affect, not likely to adversely affect: The appropriate conclusion when effects on the species or critical habitat are expected to be beneficial, discountable, or insignificant. Beneficial effects have contemporaneous positive effects without any adverse effects to the species or habitat. May affect, likely to adversely affect: The appropriate conclusion when there is "more than a negligible potential to have adverse effects on the species or critical habitat." In the event the overall effect of the proposed project is benefiCial to the listed species or critical habitat, but may also cause some adverse effects to individuals of the listed species or segments ofthe critical habitat, then the proposed project is "likely to adversely affect" the listed species or critical habitat. It is not possible for NMFS to concur on a "not likely to adversely affect" determination if the proposed project will cause harm to the listed species. Implementation ofthe conservation measures included in the proposed project would benefit listed Chinook, steelhead, and bull trout by increasing light penetration (primary productivity) and shoreline shallow water habitat (fish gravel), which has been shown to be used more by juvenile Chinook when compared to existing conditions. Take of any species is unlikely, and designated bull trout and Chinook critical habitat would not be destroyed or adversely modified. Therefore, the proposed project "may affect", but is "not likely to adversely affect" Chinook, steelhead, and bull trout. VII. ESSENTIAL FISH HABITAT The MSA-established procedures designed to identify, conserve, and enhance EFH for those species regulated under a federal fisheries management plan. Pursuant to the MSA, federal agencies must consult with NMFS on all actions or proposed actions, authorized, funded, or undertaken by the agency, that may adversely affect EFH (Section 305{b){2)). Essential Fish Habitat means those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity. For the purpose of interpreting this definition of EFH, "waters" Biological Assessment Page 53 Q:\Projecls\Barbee BA 20 12\20 12 Draft 8A\20 12 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism include aquatic areas and their associated physical, chemical, and biological properties that are used by fish and may include aquatic areas historically used by fish where appropriate; "substrate" includes sediment, hard bottom, structures underlying the waters, and associated biological communities; "necessary" means the habitat required to support a sustainable fishery and the managed species' contribution to a healthy ecosystem; and "spawning, breeding, feeding, or growth to maturity" covers a species' full life cycle (50 CFR 600.10). "Adverse effect" means any impact that reduces quality and/or quantity of EFH, and may include direct (e.g., contamination or physical disruption), indirect (e.g., loss of prey or reduction in species fecundity), site-specific or habitat-wide impacts, including individual, cumulative, or synergistic consequences of actions (50 CFR 600.810). An EFH consultation with NMFS is required for any federal agency action that may adversely affect EFH, including actions that occur outside EFH, such as certain upstream and upslope activities. The objectives of this EFH consultation are to determine whether the proposed project would adversely affect designated EFH and to recommend conservation measures to avoid, minimize, or otherwise offset potential adverse effects to EFH. A. DESCRIPTION OF THE PROPOSED ACTION The proposed project and action area are described in Section II of this document. B. ApPROPRIATE FISHERIES MANAGEMENT PLAN(S) Pursuant to the MSA, the Pacific Fisheries Management Council (PFMC) has designated EFH for three species of federally-managed Pacific salmon: Chinook, coho, and Puget Sound pink salmon (PFMC 1999). Freshwater EFH for Pacific salmon includes all 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 (PFMC 1999). Detailed descriptions and identification of EFH for salmon are found in Appendix A to Amendment 14 of the Pacific Coast Salmon Plan (PFMC 1999). In the Lake Washington basin, EFH is designated for Chinook and coho salmon; therefore, EFH is designated in the action area olthe proposed project. C. EFFECTS OF THE PROPOSED ACTION As previously described in Sections V and VI olthis document, the proposed project would result in the improvement of aquatic habitat. The effects on Chinook salmon critical habitat are the same as for designated EFH. D. PROPOSED CONSERVATION MEASURES Proposed conservation measures to minimize impacts to designated Chinook and coho salmon EFH are the same as those described in Section liB. E. CONCLUSION Following the listed conservation measures, as outlined in Section II B olthis document, the proposed project may cause a short-term negligible increase in turbidity/suspended sediment and a Biological Assessment Page 54 Q:\Projects\Barbee BA 2012\2012 Draft BA \2012 BA 082712 docx Cugini Property Boathouse Expanded Dredge Prism reduction in benthic invertebrates in the dredging lone. However, overall long-term water quality would be improved by removal of the toxic creosote pilings. Primary productivity and the fish forage base would be improved as a result of increased light penetration into the lake, and shoreline and instream habitat quality would be improved through the addition of fish rock. Therefore, the proposed project would not adversely affect designated EFH for Chinook and coho salmon, and would not hinder a sustainable fishery for these two species.

In this Opinion, the National Marine Fisheries Service concludes that the action, as proposed, is not likely to jeopardize the continued existence of Puget Sound Chinook and steelhead or result in the destruction or adverse modification of designated critical habitat for Puget Sound Chinook. As required by section 7 of the Endangered Species Act, the National Marine Fisheries Service provided an incidental take statement with the biological opinion, The incidental take statement describes reasonable and prudent measures the National Marine Fisheries Service considers necessary or appropriate to minimize incidental take associated with this action. The take statement sets forth a nondiscretionary term and condition. Incidental take from actions that meet the term and condition will be exempt from the Endangered Species Act take prohibition. This document also includes the results of our analysis of the action's likely effects on Essential Fish Habitat pursuant to section 305(b) ofthe Magnuson-Stevens Fishery Conservation and Management Act (MSA), and includes two conservation recommendations to avoid, minimize, or otherwise offset potential adverse effects on Essential Fish Habitat. The Conservation Recommendations are not identical to the ESA Terms and Conditions. Section 305(b) (4) (B) of the MSA requires Federal agencies to provide a detailed written response to the National Marine Fisheries Service within 30 days after receiving these recommendations. @ Prinkd on Recycled Paper -2 - If the response is inconsistent with the Essential Fish Habitat conservation recommendation, the U.S. Army Corps of Engineers must explain why the recommendations will not be followed, including the justification for any disagreements over the effects of the action and the recommendations. In response to increased oversight of overall Essential Fish Habitat program effectiveness by the Office of Management and Budget, the National Marine Fisheries Service established a quarterly reporting requirement to detennine how many conservation recommendations are provided as part of each Essential Fish Habitat consultation and how many are adopted by the action agency. Therefore, in your statutory reply to the Essential Fish Habitat portion of this consultation, we ask that you clearly identifY the number of conservation recommendations accepted. If you have questions regarding this consultation, please contact Brianna Blaud at (206) 526- 4749 or brianna.blaud@noaa.gov.

With respect to designated critical habitat, the following analysis relied only on the statutory provisions of the ESA, and not on the regulatory definition of "destruction or adverse modification" at 50 CFR 402.02. The Essential Fish Habitat (EFH) consultation was prepared in accordance with section 305(b)(2) of the Magnuson-Stevens Fishery Conservation and Management Act (MSA) (16 U.S.C. 1801, et seq.) and implementing regulations at 50 CFR 600. The administrative record for this consultation is on file at the Washington State Habitat Office in Lacey, Washington. Background and Consultation History On January 9, 2008, NMFS received a letter dated January 8, 2008, from the U.S. Army Corps of Engineers (COE) requesting consultation under Section 10 of the Rivers and Harbors Act of 1898 and Section 404 of the Clean Water Act to authorize the maintenance dredging and boathouse renovation by Barbee Mills Company (applicant), in King County, Washington. The COE determined the proposed action "may affect, but is not likely to adversely affect" Puget Sound (PS) Chinook salmon, PS steelhead, and PS Chinook salmon critical habitat. After reviewing the consultation, NMFS determined that the actions may adversely affect the listed species arid critical habitat, and initiated a formal consultation. Proposed Action The proposed action is issuance of a permit by the COE under section 10 of the Rivers and Harbors Act of 1898 and Section 404 of the Clean Water Act to authorize the maintenance dredging and boathouse renovation by Barbee Mills Company (applicant), in King County, Washington. The dredging maintains navigational access to a boathouse located to the south of May Creek. It is estimated that the area will need dredging every three to four years to maintain navigable depths, but the total amount to be removed over the 10 year life of this Opinion will not exceed 4,000 cubic yards. The proposed dredging area is approximately 10,000 square feet, ranging from 4 feet to 12 feet deep. The only shallow area proposed for excavation is located directly under the boathouse, to make it more boat accessible. The dredging will increase the depth by approximately one foot, maintaining existing slopes, and avoiding any shallow water or nearshore habitat. To minimize the effects of dredging in the area, 40 cubic yards of spawning gravel will be installed along 2,100 square feet of shoreline and vegetation will be planted along 200 linear feet of shoreline. The boathouse renovations will improve the integrity and the light transmission through the structure. The solid skirting around the boathouse extending from the bottom of the structure to the lake bed will be replaced with an open 4 inch mesh skirting that extends to the ordinary low water level. Approximately 20 percent of the boathouse walls will be replaced with translucent material, improving the light transmission. The surrounding floats will be renovated, replacing the existing eighteen creosote pilings with twelve 18-inch steel pilings using a vibratory pile driver, and replacing the solid decking with grated material. Action Area The action area is in the Lake Washington shoreline corresponding to the immediate vicinity of 3901 Lake Washington Boulevard Avenue, near Renton. The action area includes EFH for Chinook salmon and coho salmon. ENDANGERED SPECIES ACT The ESA establishes a national program to conserve threatened and endangered species offish, wildlife, plants, and the habitat on which they depend. Section 7(a)(2) of the ESA requires Federal agencies to consult with the U.S. Fish and Wildlife Service, NMFS, or both, to ensure that their actions are not likely to jeopardize the continued existence of endangered or threatened species or adversely modify or destroy their designated critical habitats. Section 7(b)( 4) requires the provision of an incidental take statement that specifies the impact of any incidental taking and includes reasonable and prudent measures to minimize such impacts. Biological Opinion This Opinion presents NMFS' review of the status of each listed species of Pacific salmon and steelhead' considered in this consultation, the condition of designated critical habitat, the environmental baseline for the action area, all the effects of the action as proposed, and cumulative effects (50 CRF 402.14(g»). For the jeopardy analysis, NMFS analyzed those combined factors to conclude whether the proposed action is likely to appreciably reduce the likelihood of both the survival and recovery of the affected listed species. The critical habitat analysis determines whether the proposed action will destroy or adversely modify'designated critical habitat for listed species by examining any change in the conservation valued of that critical habitat. This analysis relies on statutory provisions of the ESA, including those in section 3 that define "critical habitat" and "conservation," in section 4 that describe the designation process, and in section 7 that sets forth the substantive protections and procedural aspects of consultation, and on agency guidance for application of the "destruction or adverse modification" standard. Status of Species This section defines the biological requirements of each listed species affected by the proposed action, and the status of each designated critical habitat relative to those requirements. Listed I An 'evolutionarily significant unit' (ESU) of Pacific salmon (Waples 1991) and a 'distinct population segment' (DPS) of steelhead (final steel head FR notice) are considered to be 'species,' as defmed in Section 3 of til. ESA. 2 species facing a high risk of extinction and critical habitats with degraded conservation value are more vulnerable to the aggregation of effects considered under the environmental baseline, the effects of the proposed action, and cumulative effects. Puget Sound Chinook NMFS listed PS Chinook salmon as threatened (March 1999, 64 FR 14308). The Puget Sound Chinook salmon Evolutionarily Significant Unit (ESU) has been defined to include all PS Chinook salmon populations residing below impassable natural barriers (e.g., long-standing natural water falls) in the Puget Sound region from the Nooksack River to the Elwha River on the Olympic Peninsula, inclusive. The status of individual populations within Puget Sound is assessed based on their abundance, productivity, diversity, and spatial structure. Within the action area in Lake Washington, there are two native popUlations (the North Lake Washington population and the Cedar River population) that use the area from rearing and migration. A third population, the Issaquah stock, is not included in the assessment because they are a non-native stock from the Issaquah Hatchery that has been in operation since the 1930s (WDFW 2004). The Issaquah stock will not be consulted on in this Opinion. Overall abundance of this ESU has declined substantially from historical levels, and many populations are small enough that genetic and demographic risks are likely to be relatively high (March 9, 1998, 63 FR 11494). Historic abundance has been estimated to be approximately 609,000 adult returns (Myers et al. 1998), while average present day (J 998-2002) abundance of natural origin spawners is 30,182 fish (NMFS 2005). NMFS (Good et al. 2005) listed approximately 331 geometric mean spawners in North Lake Washington popUlation and 327 in the Cedar River population, and no estimates of historical abundance for comparison. The general trend in the abundance for the North Lake Washington Tributary Chinook salmon has remained generally consistent, with escapements between 200 and 500 adults (WDFW 2004). The Cedar River Chinook salmon have shown a long-term negative trend in escapements and chronically low escapement values CWDFW 2004). Productivity is the measurement ofa population's growth rate through all or a portion of its life- cycle. A tool to estimate productivity is the median population growth rate (lambda), calculated by the measure of 10ng-and short-term trends. Long-and short-term trends are calculated on all spawners, and the short-term lambda is calculated assuming the reproductive success of naturally spawning hatchery fish is equivalent to that of natural-origin fish (Good et al. 2005). A lambda greater than I represents a population that is replacing itself. For salmon recovery, the target goal lambda amount is 3.4 to increase abundance to a level that would remove the populations from the threat of extinction. The lambda for North Lake Washington short term trend is 1.07 (±O.O7) (Good et aI., 2005), indicating the population is just replacing itself, and a population greater than one indicates an increase in productivity that will result in a rise in abundance. For the Cedar River, short term lambda is (0.99±0.07) also indicating the population is probably just replacing itself. Significant population growth will require an increase in productivity. 3 Diversity is important to population viability because: 1) It allows a species to use a wider array of environments than they could without it; 2) It protects against short term spatial and temporal changes in the environment, increasing the likelihood that some individuals would survive and reproduce when faced with environmental variation; and 3) Genetic diversity provides the raw material for surviving long-tenn environmental changes. Genetic analysis of the three populations in the Lake Washington basin indicated that the North Lake Washington Tributary population and the Cedar River Chinook are significantly different (WDFW 2004). Therefore, the genetic differentiation between the two populations increases the possibility for recovery when faced with an environmental change and an increase of available habitat. The spatial structure of habitat must support the population at the desired productivity, abundance, and diversity levels through short-term environmental perturbations, longer tenn environmental oscillations, and through natural patterns of disturbance regimes. Assessing the adequacy of the spatial structure should include considering whether the population has: 1) Enough habitat to support growth, abundance, and diversity criteria; 2) Habitat of sufficient quality to support the life history activities; pennanent or seasonal connectivity to allow adequate migration between spawning, rearing, and migration patches, and; 3) A geographical distribution of habitat that minimizes the probability of a significant portion of a population being lost due to a single catastrophic event. The criteria for identifying core areas for spatial structure are focused on spawning, because spawning is the geographic starting point for structuring populations and there is the most information available on this life phase (Martin et al. 2004). In the Cedar River, all but one of the spawning patches are two to four miles apart and ranged from 0.1 to 2 miles long (Martin et al. 2004). The status of Chinook salmon populations in the Lake Washington basin were described in the Salmon and Steelhead Inventory (SaS1) report (WDFW and PSIT 2004). The North Lake Washington Tribs Chinook salmon is rated "healthy" based on their consistent escapement. The Cedar Chinook salmon is rated as "depressed" based on their long-term negative trend and low escapement numbers. Puget Sound Steelhead The NMFS defined the PS Steelhead Distinct Population Segment (DPS) to include naturally spawning steelhead stocks below natural and manmade impassable barriers, in streams and rivers ranging from the Canadian border (Nooksack River basin), south through Puget Sound and Hood Canal, north and west to the Elwha River, which empties into the eastern Strait of Juan de Fuca. The PS Steelhead are at risk of becoming endangered in the foreseeable future, and were listed as 4 threatened on June 11, 2007 (72 FR 26722). The status of individual populations within Puget Sound is assessed based on their abundance, productivity, diversity, and spatial structure. The two populations of steelhead within the Lake Washington populations use Lake Washington for migrating, holding and rearing. Early abundance analysis from catch records in 1889 indicate that the catch peaked at 163,796 individuals in 1895 (Little, 1898). Assuming a harvest rate of 30-50 percent, Little (1898) estimated that the peak run size ranged from 327,592 to 545,987 fish. In the 19908 the total run size for major stocks in this DPS was greater than 45,000, with total natural escapement of about 22,000, a fraction of the 1889 abundance. The abundance treat for the Cedar River population is decreasing. Counts between 1980 and 2004 estimate an escapement of 137.9 natural spawners, and more recent data (2000-2004) has the estimates at 36.8, showing a steep decline (Hard et aI. 2007). The Lake Washington population shows a similar declining trend with 308.1 natural spawners between 1980 and 2004, and 36.8 between 2000 and 2004 (Hard et al. 2007). To estimate existing productivity in Lake Washington steelhead, Scott and Gill (2006) used escapement data or indices of escapement from the previous eight years to create a time series. Population viability analyses were conducted under the assumption that only anadromous spawners contribute to the abundance of each popUlation. This assumption may result in estimates of extinction that are too high because the presence of resident forms of O. mykiss (rainbow trout) may reduce the likelihood of extinction. The Lake Washington winter-run stee1head last escapement data was listed at 44, with a growth rate estimate of -0.16, indicating a decrease in productivity. The relative risk of extinction for populations of steelhead in the Puget Sound region is very high, because productivity is poor. More recent productivity analysis included lambda calculations, showing Cedar River steelhead lambda at 0.808 (±{1.004), and Lake Washington steel head lambda at 0.802 (±0.002) (Hard et al. 2007), supporting Scott and Gill's (2006) productivity decline. Examples of diversity among salmonids include morphology, fecundity, run timing, spawn timing, juvenile behavior, age at smolting, age at maturity~ egg size, and development rate, among others (McElhany et al., 2000). Of these traits, some are genetically based, while others are likely a result of a combination of genetic and environmental factors. Allozyme analysis of steel head sampled in the Cedar River in 1994 clusters them with winter steelhcad in the Green, White, and Puyallup rivers, and with some Snohomish basin steelhead stocks (WDFW 2004). The Cedar River population is a distinct population that has undergone minimal hatchery introgression (Hard et al. 2007). No genetic analysis has been performed on the Lake Washington steel head population. The metrics and benchmarks for evaluating the adequacy ofa population's spatial structure include quantity, quality, connectivity, dynamics, and catastrophic risks. Scott and Gill (2006) estimated that up to 19 percent of the pre-settlement range has been lost for the winter-run steelhead within the Cedar/Sammamish basin. Based on the above described criteria and conditions, the status of the Lake Washington winter steel head was defined in the SaSI report (WDFW 2004). Based on the chronically low 5 escapement and short-term severe decline in escapements, the stock status declined from "depressed" in 1994 to "critical" in 2002. Status of Critical Habitat The NMFS reviews the status of designated critical habitat affected by the proposed action by examining the condition and trends of Primary Constituent Elements (PCEs) throughout the designated area. The PCEs are the physical and biological features identified as essential to the conservation. Sites include freshwater spawning, freshwater rearing, freshwater migration, estuarine areas, nearshore marine areas, and offshore marine areas. The critical habitat in Lake Washington contains freshwater rearing and freshwater migration. Essential physical and biological features for freshwater rearing and migration include water quantity and floodplain connectivity that support juvenile growth and mobility; water quality and forage that support juvenile development; and natural cover consisting of shade, large wood, log jams, beaver dams, aquatic vegetation. large rocks and boulders. side channels, and undercut banks and water free of artificial obstructions that support juvenile and adult mobility and survival. At the time that each habitat area was designated as critical habitat, that area contained one or more PCEs within the acceptable range of values required to support the biological processes of listed species. As part of the process to designate critical habitat within the PS Chinook salmon ESU, NMFS assessed the conservation value of habitat within freshwater, estuarine and nearshore areas at the fifth field hydrologic unit code (HUC) scale, across the entire range of the ESU. The HUC scale corresponds generally to the watershed scale, and these areas were rated as providing "low", "medium", or "high" conservation value. NMFS rated the fifth field HUC within which the action area lies as having a "medium" conservation value. As described in more detail within the Environmental Baseline section below, PCEs of critical habitat within the project and action area are generally degraded from a variety of human-induced habitat process and structural changes. Environmental Basel ine The 'environmental baseline' includes the past and present impacts of all Federal, state, or private actions and other human activities in the action area, the anticipated impacts of all proposed Federal projects in the action area that have already undergone formal or early section 7 consultation, and the impact of state or private actions which are contemporaneous with the consultation in process (50 CFR 402.02). Lake Washington is the second largest natural lake in the state of Washington with 80 miles of shoreline, including 30 miles along the shore of Mercer island (Shared Strategy 2007). Lake Washington also has the highest human popUlation of any Water Resource Inventory Area (WRIA) in Washington State. Over 82 percent of the Lake Washington shoreline is armored and is shaded by more than 2,700 piers and docks (Shared Strategy 2007). Regulated lake levels and extensive armoring have hampered sediment transport and sandy beaches need to be augmented by periodic sediment supplies. The lack of riparian vegetation due to clearing and development has led to an increase in temperature, a loss in organic debris, and a reduction in insect recruitment. The loss of channel and shoreline complexity including a lack of woody debris and 6 available shallow water and overwater has led to a decline in nearshore habitat vital to rearing. The presence of in water structures, such as piles, skirting, and piers hinder migration ofboth juveniles and adults. Many tributaries and streams have fish passage barriers with the construction ofroad crossings, weirs, and dams, hindering salmon migration and reducing spatial structure. The water quality and sediment quality of Lake Washington have been degraded by pollutants and high temperatures (Shared Strategy 2007). A report by WDFW and PSIT (2004) states that current habitat conditions constrain productivity and prevent the achievement of recovery goals. The action area is located in a cove that is subject to sediment deposits just to the south of May Creek. The water depth is approximately 12 feet deep in the center of the cove with gradual slopes leading to the shoreline. The boathouse is located at the innermost shoreline position of the cove. Skirting extending from the bottom of the structure to the lake bottom completely shades the foot print oftha boat house. There is a series of solid decking floats paralleling the shoreline approximately 30 feet waterward, held in place by eighteen creosote treated piles. The proposed dredge footprint is located waterward of the floats and underneath the boathouse. Effects of the Action Adverse effects on listed species include short-term reduction in water quality, such as increases in suspended sediment and noise, and a potential delay in adult migration, and long-term reduction in shallow water habitat, maintenance of overwater shading, and in-water obstacles. Some of the effects of the action will be so small (changes in water quality) or timed such that salmon and steelhead are exceedingly unlikely to experience them (increased sound pressure levels from pile driving). Best Management Practices, such as the use of silt curtains and sound attenuation devices will further minimize the effects from construction. As such, those effeds are insignificant or discountable and are not analyzed further in this consultation. Delayed Spawning Within the South Lake Washington, the work window for construction activities is designed to avoid work in the nearshore during juvenile migration and rearing. Between February and June, most juvenile Chinook salmon migrate and rear along the shore, restricting the in water work window to fall between July 16 th December 31 st. Adult Chinook salmon migrate and enter streams and tributaries between June and September, and spawning occurs between September and November. Due to the action areas' close proximity to May Creek, the Applicant will voluntarily abstain from dredging activities between mid-September and November; however there may still be overlap hindering adult migration up the streams and tributaries. The dredging activity may temporarily harass and displace juveniles and adults, which may result in delayed spawning activity by temporarily hindering adult access to May Creek to spawning habitat. Under the worst circumstances there will only a few fish will be affected and there it is unlikely to prevent spawning. 7 Loss of Shallow Water Habitat Dredging increases water depth by removing material from the lake bottom. The increase in depth potentially degrades habitat conditions for rearing juvenile salmonids that forage on organic debris, insects, plankton, and benthic organisms and seek refuge in shallow water habitat. Greater depths are also used by predator species such as smallmouth bass (Micropterus dolomieu) (Tabor et al. 2007). The loss of the shallow water increases the opportunity for take, due to predation and decreased opportunity for forage. The applicant will avoid dredging in the nearshore shallow water as much as possible, and will improve the nearshore habitat with planting along 200 feet of shoreline and installing spawning gravel over 2100 square feet of the shoreline. In addition the area being dredged is already too deep to provide high quality habitat for juvenile salmonids. Overwater Shading Toft et al. (2007) assessed the abundance offish at the various types of shoreline and determined that juvenile salmon were not usually observed underneath overwater structures. Juveniles tend to avoid piers because they physically block normal movement patterns or decrease light levels (Toft et al. 2007). Additionally, predatory bass species aggregate around in-water and over- water structures. The amount of light transmission at the project site continues to be compromised through the excessive walkway widths in nearshore floats. By using grated decking on the floats and using transparent siding on 20 percent of the boathouse, the applicant ameliorates some of the adverse affects by increasing the light penetration. However, there is still an excessive amount by the boathouse, which will still completely cover approximately 1,580 square feet, half of that within 30 feet of the shoreline. Migration Obstacles Structures within the water act as barriers and hinder access to habitat. Migration obstacles cause fish to change their course, expending unnecessary energy to avoid pilings, skirting, and other similar obstacles. The proposed action will reduce the nwnber of pilings, and using steel material instead of creosote treated piles will reduce the size of the obstacles. The use of 4 inch mesh skirting will be an improvement over the existing solid skirting that extends to the lake bottom, but the mesh skirting will still extend into the water during ordinary high water, creating migration obstacles for larger fish near the surface. Relevance of the Effects of the Action to Fish Individual Chinook salmon and steelhead will be directly and indirectly affected by the dredging of an inlet south of May Creek, and the repair of a nearby boathouse. The loss of shallow water will slightly decrease the amount of rearing habitat available to juvenile salmonids for foraging and refuge from predation. Although dredging in the nearshore will be kept to a minimum, the degraded nearshore habitat caused by existing structures will be maintained. Construction activities during the approved work window based on the juvenile migration timing may affect adult Chinook salmon, delaying their migration into May Creek. 8 The proposed actions occurred in Lake Washington adjacent to May Creek. The effects of the action are anticipated to affect habitat conditions for the described Chinook salmon and steelhead populations that rear or migrate in the action area, primarily Cedar River populations of PS Chinook salmon and PS steelhead. Predation on juveniles is expected to reduce the number of smolts that migrate from the Lake Washington basin. Although take associated with the action may slightly reduce the ahundance and productivity of the Cedar River PS Chinook salmon and PS steelhead, NMFS does not expect the likelihood of survival and recovery of the ESUs to be significantly reduced. Effects on Critical Habitat The PCEs that the action area provides are freshwater rearing, and migration. The short term effects of activities at the project site, such changes in water quality (increased turbidity) and noise (increased sound pressure levels from pile driving), are temporary and localized and will not affect the functional role of PCEs. in the action area as a threshold matter. As such, they will have no effect on conservation value of critical habitat in the watershed in which the action area lies. The long term effects of the actions include reduction in shallow water habitat, maintenance of overwater shading, and in-water obstacles. The presence of vertical bulkheads directly impacts the habitat by removing shallow water, a requirement for rearing salmonids. Overwater structures increase the amount of shading, providing cover for predators and decreasing the amount of light that penetrates through to the water. The effects of the overwater structure are minimized through the use of grated decking material, which allow for light transmission. Piling and skirting represent migration barriers and obstacles that hinder access to habitat. Cumulative Effects Cumulative effects are those effects offuture state or private activities, not involving Federal activities, that are reasonably certain to occur within the action area of the Federal action subject to consultation (50 CFR 402.02). By the year 2025, the projected human population growth for King County is 355,356 people, which is a 20 percent increase (Redman et aI., 2005). With these pr~jections, NMFS assumes that future private and state actions will continue within the action area, increasing as population density rises. New development is likely to further reduce the conservation value of habitat within the watershed through water withdrawals, stormwater quality degradation and increased volumes, loss of riparian functions, and encroachment to floodplains. The NMFS believes that the existing King County regulatory mechanisms to minimize and avoid impacts to watershed function from future commercial, industrial, and residential development are generally not adequate, and/or not implemented sufficiently. Thus, while these existing regulations could decrease adverse effects to watershed function, they still allow incremental degradation to occur, which accumulate over time, and when added to the degraded 9 environmental baseline, further degrade habitat conditions, and reduce habitat quality and suitability for PS Chinook salmon and PS steelhead. Conclusion The effects of action will not affect any of the characteristics of viable salmon or steelhead populations. Nor will the action influence the conservative role of critical habitat at the watershed level. After reviewing the status of PS Chinook salmon and PS steelhead, the environmental baseline for the action area, the effects of the proposed action, and cumulative effects, NMFS concludes that the action, as proposed, is not likely to jeopardize the continued existence of PS Chinook salmon and PS steel head and is not likely to destroy or adversely modify the designated critical habitats for PS Chinook sahnon. These conclusions are based on the following considerations: 1. Dredging will only occur underneath the boathouse and in the center of the cove, waterward of the floats, avoiding dredging in shallow water habitat where possible; 2. Planting along the shoreline and installing spawning gravel will improve the nearshore habitat for rearing juveniles; 3. The use of transparent material on the boathouse and grated decking on the floats improves light transmission; and, 4. The replacement of 20 creosote piles with twelve IS-inch steel piles improves the water quality and decreases migration obstacles. Therefore, the proposed action is not expected to appreciably reduce long-term survival and recovery ofPS Chinook salmon and PS steelhead. Conservation Recommendations Section 7(a) (1) of the ESA directs Federal agencies to use their authorities to further the purposes of the ESA by carrying out conservation programs for the benefit of the threatened and endangered species. The following recommendations are discretionary measures that NMFS believes are consistent with this obligation and therefore should be carried out by the COE: I. Minimize impacts of overwater structures by minimizing the amount of overwater structures near the immediate shoreline (within 30 feet of shore) and limiting the walkway to four feet wide or less. If future actions are taken to modify the existing pier, all other structures such as ells, boatlifts, or moorage covers, should be relocated to be at least 30 feet from shore, and the size of the walkway should be reduced to a width of four feet. Please notify NMFS if the COE carries out any of these recommendations so that we will be kept informed of actions that minimize or avoid adverse effects and those that benefi t listed species or their designated critical habitats. 10 Reinitiation of Consultation Reinitiation of formal consultation is required and shall be requested by the Federal agency or by NMFS where discretionary Federal involvement or control over the action has been retained or is authorized by law and: (a) If the amount or extent of taking specified in the incidental take statement is exceeded; (b) if new information reveals effects of the action that may affect listed species or designated critical habitat in a manner or to an extent not previously considered; (c) if the identified action is subsequently modified in a manner that has an effect to the listed species or designated critical habitat that was not considered in the Opinion; or (d) if a new species is listed or critical habitat is designated that may be affected by the identified action (50 CFR 402.16). To reinitiate consultation, contact the Washington State Habitat Office ofNMFS and refer to the NMFS Number assigned to this consultation. Incidental Take Statement Section 9( a)(l) of the ESA prohibits the taking of endangered species without a specific permit or exemption. Protective regulations adopted pursuant to section 4( d) extend the prohibition to threatened species. Among other things, an action that harasses, wounds, or kills an individual of a listed species or harms a species by altering habitat in a way that significantly impairs its essential behavioral patterns· is a taking (50 CFR 222.1 02). Incidental take refers to takings that result from, but are not the purpose of, carrying out an otherwise lawful activity conducted by the Federal agency or applicant (50 CFR 402.02). Section 7(0)(2) exempts any taking that meets the terms and conditions of a written incidental take statement from the taking prohibition. Amount or Extent of Take The affects of the action will co-occur with the presence of both Puget Sound Chinook and steelhead. Fish exposed to those effects will respond to their exposure in various ways, but some are certain to respond by changing their normal behavior in the action area such that they will be injured or killed. Therefore, take of Puget Sound Chinook and Puget Sound steelhead is reasonably certain to occur. For actions that cause take in the form of harm, NMFS' ability to quantify the amount of take in numbers of fish can be difficult if not impossible to accomplish because of the range of individual fish responses to habitat change. Some will encounter changed habitat and merely react by seeking out a different place in which to express their present life history. Others might change their behavior, causing them to express more energy, suffer stress, or otherwise respond in ways that impair their ·present or subsequent life histories. Yet others will experience changed habitat in way that kills them. While this uncertainty makes it impossihle to quantity take in the form ofharm in terms of numbers of animals injured or killed, the extent of habitat change to which present and future generations offish will be exposed is readily discemable and presents a reliable measure of the extent of take that can be monitored and tracked. Therefore, when the specific number of 11 individuals "hanned" cannot be predicted, NMFS quantifies the extent of take based on the extent of habitat modified (51 FR 19926 at 19954; June 3, 1986). Take from this project includes reduced production of prey species and spawning delay associated with dredging activities. The extent of habitat affected by dredging is 10,000 square feet, which will occur near the mouth of May Creek. The estimated extent of habitat affected by proposed action represents the extent of take exempted in this incidental take statement. These extents are readily observable and therefore suffice to trigger reinitiation of consultation, if exceeded and necessary (see H.R. Rep. No 97-567, 97th Cong., 2d Sess. 27, 1982). This consultation does not exempt take from the existing boathouse and float locations. Reasonable and Prudent Measures Reasonable and prudent measures are nondiscretionary measures to avoid or minimize take that must be carried out by cooperators for the exemption in section 7(0)(2) to apply. The COE has the continuing duty to regulate the activities covered in this incidental take statement where discretionary Federal involvement or control over the action has been retained or is authorized by law. The protective coverage of section 7(0)(2) will lapse if the COE fails to exercise its discretion to require adherence to terms and conditions of the incidental take statement, or to exercise that discretion as necessary to retain the oversight to ensure compliance with these terms and conditions. Similarly, if any applicant fails to act in accordance with the terms and conditions of the incidental take statement, protective coverage will lapse. The NMFS believes that full application of conservation measures included as part of the proposed action, together with use of the reasonable and prudent measures and terms and conditions described below, are necessary and appropriate to minimize the likelihood of incidental take of listed species due to completion of the proposed action. The COE shall: I. Change the work window to accommodate migrating adult salmon. Terms and Conditions To be exempt from the prohibitions of section 9 of the ESA, the COE and its cooperators, including the applicant, if any, must fully comply with conservation measures described as part of the proposed action and the following terms and conditions that implement the reasonable and prudent measures described above. Partial compliance with these terms and conditions may invalidate this take exemption, result in more take than anticipated, and lead NMFS to a different conclusion regarding whether the proposed action will result in jeopardy or the destruction or adverse modification of designated critical habitats. 1. To implement Reasonable and Prudent measure No.1, the COE shall ensure that: No in-water work takes place during the peak adult migration into streams and tributaries. May Creek is located directly to the north of the action area, and has 12 both vital spawning and rearing habitat. By reducing the work window from July 16 th to September 15 th , it decrease the effect on migrating and spawning adults. NOTICE. If a sick, injured or dead specimen of a threatened or endangered species is found, the finder must notify NMFS Law Enforcement at (206) 526-6133 or (800) 853-1964. The finder must take care in handling of sick or injured specimens to ensure effective treatment, and in handling dead specimens to preserve biological material in the best possible condition for later analysis of cause of death. The finder also has the responsibility to carry out instructions provided by Law Enforcement to ensure that evidence intrinsic to the specimen is not disturbed unnecessarily. MAGNUSON-STEVENS FISHERY CONSERVATION AND MANAGEMENT ACT TI1e consultation requirement of section 305(b) of the MSA directs Federal agencies to consult with NMFS on all actions, or proposed actions that may adversely affect EFH. Adverse effects include the direct or indirect physical, chemical, or biological alterations of the waters or substrate and loss of, or injury to, benthic organisms, prey species and their habitat, and other ecosystem components, if such modifications reduce the quality or quantity of EFH. Adverse effects to EFH may result from actions occurring within EFH or outside EFH, and may include site-specific or EFH-wide impacts, including individual, c\Unulative, or synergistic consequences of actions (50 CFR 600.810). Section 305(b) also requires NMFS to recommend measures that may be taken by the action agency to conserve EFH. Based on information provided in the BE and the analysis of effects presented in the ESA portion of this document, NMFS concludes that proposed action will have the following adverse effects on EFH designated for Chinook salmon and coho salmon. • Reduced shallow water habitat, important to rearing juvenile salmonids. • Maintain degrading structure placement with the excessive amount of structures within 30 feet of the shore that create canlouflage and cover for predatory species, and decrease the light transmission through the boathouse and floats. EFH Conservation Recommendations The NMFS believes that implementation of one of the following conservation measures are necessary to avoid, mitigate, or offset the impact of the proposed action on EFH. While NMFS understands that the COE intends to conduct the proposed action with the included minimization and mitigation measures described in the Opinion, it does not believe that these measures are sufficient to address the adverse impacts to EFH described above. 1. Minimize effects on shallow water habitat by avoiding dredging in the nearshore, shallow water habitat. 2. Minimize effects of the overwater structures by increasing the extent of light transmission to the lake bottom beneath the boathouse and piers. 13 Statutory Response Requirement . Federal agencies are required to provide a detailed written response to NMFS' EFH conservation recommendations within 30 days of receipt of these recommendations (50 CFR 600.9200)(1)). The response must include a description of measures proposed to avoid, mitigate, or offset the adverse affects of the activity on EFH. If the response is inconsistent with the EFH conservation recommendations, the response must explain the reasons for not following the recommendations. The reasons must include the scientific justification for any disagreements over the anticipated effects of the proposed action and the measures needed to avoid, minimize, mitigate, or offset such effects. Supplemental Consultation The COE must reinitiate EFH consultation with NMFS if the proposed action is substantially revised in a way that may adversely affect EFH, or if new information becomes available that affects the basis for NMFS' EFH conservation recommendations [50 CFR 600.920(k)].
