The bulkhead is located both in the May Creek Reach A and the Lake Washington Reach C shoreline overlay areas. The project is a repair and maintanence of approximately 50 percent of the existing 4 -foot tall bulkhead piled rocks along 81 lineal feet of shoreline. Approximately 40 cubic yards of 4 to 6 -inch crushed rock and 40 cubic yards of 1 -inch minus crushed rock would be placed landward of the bulkhead to improve drainage and prevent future erosion of the soil. Approximately 40 cubic yards of 1 -inch minus spawning gravel is proposed waterward of the bulkhead. A silt curtain would be placed around the worksite. The applicant for the $32,000 project is also seeking authorization from Washington Department of Fish and Wildlife and Army Corps of Engineers. The submitted biological evaluation of impacts has made a determination of no - net -loss of ecological function. A planting mitigation plan was previously approved for a residential shared dock to be constructed on this subject site and the site to the north through LUA14-001181. A geotechnical report was submitted stating the problems identified with the existing wall that is falling into the lake in places and the erosion through the wall that is occurring.

SEC-TWN-R: N W Quarter of Section 32, Township 24 N, Range 5 E, in the City of Renton, King County, Washington WATER BODY/WETLAND: May Creek, Reach A and Lake Washington, Reach C Work on shoreline stabilization structures requires review of the Shoreline Master Program and that proposed projects are in compliance with RMC 4-3-090F.4 "Shoreline Stabilization". c. Existing Shoreline Stabilization Structures: Existing shoreline stabilization structures not in compliance with this Code may be retained, repaired, or replaced if they meet the applicable criteria below: i. Repair of Existing Structures: An existing shoreline stabilization structure may be repaired as long as it serves to perform a shoreline stabilization function for a legally established land use, but shall be subject to the provisions below if the land use for which the shoreline stabilization structure was constructed is abandoned per RMC 4- 10-060, Nonconforming Uses, or changed to a new use. Staff Response: The proposal is a repair of an existing structure for a legally established single family home and therefore can be repaired. ii. Additions to Existing Structures: Additions to or increases in size of existing shoreline stabilization measures shall be considered new structures. Staff Response: The proposal for repair and maintenance is not being added to or increased in size compared to the existing bulkhead and therefore is not considered a new structure. iii. Changes in Land Use: An existing shoreline stabilization structure established to serve a use that has been abandoned per RMC 4-10-060, Nonconforming Uses, discontinued, or changed to a new use may be retained or replaced with a similar structure. Staff Response: Not applicable as there is no change in land use at the subject site, where the site continues to be a residential use.

Waterward Replacement Prohibited for Structures Protecting Residences: Replacement walls or bulkheads, if allowed, shall not encroach waterward of the ordinary high-water mark or existing structure unless the residence was occupied prior to January 1, 1992, and there are overriding safety or environmental concerns. In such cases, the replacement structure shall abut the existing shoreline stabilization structure. Staff Response: The proposal for repair and maintance of the existing wall, with approximately fifty percent of the bulkhead rocks to be replaced, is not proposed to encroach waterward of the ordinary high-water mark. v. Restoration and Maintenance of Soft Shorelines Allowed: Soft shoreline stabilization measures that provide restoration of shoreline ecological functions may be permitted waterward of the ordinary high-water mark. Replenishment of substrate materials to maintain the specifications of the permitted design may be allowed as maintenance. Staff Response: The proposal includes approximately 40 cubic yards of 1 -inch minus spawning gravel waterward of the bulkhead. The applicant is seeking additional approvals from state Department of Fish and Wildlife and Army Corps of Engineers for the project including the placement of the spawning gravel waterward at the bulkhead. vi. No Net Loss: Where a net loss of ecological functions associated with critical habitats would occur by leaving an existing structure that is being replaced, the structure shall be removed as part of the replacement measure. Staff Response: A determination of no net loss for the proposed bulkhead repair and maintenance was provided through biological evaluation, prepared by Marine Surveys and Assessments, dated April 10th 2015. Therefore, no removal of any existing structure is required.

A shoreline exemption and environmental review are required from the City of Renton. The project site and adjacent properties are zoned as Residential l Odu/ac (R-10). The project site is on the shoreline of Lake Washington and is approximately 175' from May Creek. Richard DiCerchio is the owner of the property. The property is a single family residential lot with an existing single family house. The existing bulkhead is constructed of rock and is approximately 4 feet in height. The bulkhead is in poor condition and sections of the bulkhead have collapsed into the lake. There is erosion occurring to the soil landward of the bulkhead. The bulkhead will be repaired by rebuilding the bulkhead which is approximately 81 lineal feet in length. Approximately 50% +/- of the existing bulkhead rocks will be replaced. Forty cubic yards of 4" to 6" crushed rock and forty cubic yards of 1" minus crushed rock will be added landward of the bulkhead to improve drainage and prevent erosion of the soil landward of the bulkhead. Forty cubic yards of 1" minus spawning gravel will be placed waterward of the bulkhead as required by the Washington Department of Fish and Wildlife. Geotech filter fabric will be placed between the soil and the crushed rock to further prevent erosion. The existing soil type is norma sandy loam. A floating silt curtain will be placed around the work area to contain turbidity to the work area. The estimated fair market value of the project is $32,000. The work is exempt from the requirement of a shoreline substantial development permit because it is repair of an existing structure in like kind (WAC 173-27-040). The work will take place during the summer or fall of 2015. Authorization from the Army Corps of Engineers and the Washington Department of Fish and Wildlife is required for the project. � EXHIBIT 5 (36O) 385-4073 S21 Snagstead Way marinesurveys.inc@gmail.com Port Townsend WA 98368 SSNX ADDENDUM: Addition of Proposed Repair of Existing Bulkhead April 10`b, 2015 For: DiCerchio/ Barbee Mill Waterfront LLC Joint -Use Pier Project 4005 Williams Ave. N. Renton, WA 98056 Case # , Biological Evaluation Dated August 25th, 2014 To: Whom it may concern, Please accept this addendum letter for the addition of the repair of an existing bulkhead to the original Biological Evaluation for the DiCerchio Pier, Ramp, and Float project dated August 25th, 2014. This letter describes the nature of the additional project component, addresses any potential impacts of this addition as well as provides an impact determination and net -loss analysis. A. Project Description The proponents are proposing to repair an existing bulkhead at the Dicerchio site (see Figures 1-3). The repair will consist of restacking rocks and installing crushed rock drainage material landward of the existing bulkhead. It is estimated that approximately 50% plus or minus of the existing bulkhead rocks will be replaced with new rocks. Forty cubic yards of 4" to 6" crushed rock and 40 cubic yards of minus crushed rock will be added landward of the bulkhead for drainage material. In addition, 40 cubic yards of spawning gravel mix will be added waterward of the repaired bulkhead as mitigation. B. Impacts of the Project The proposed project is a bulkhead repair project, not a new bulkhead project. Therefore, there will be no change in the baseline habitat conditions. In fact, the addition of the spawning gravel mix will actually improve the baseline habitat conditions. C. Net -Loss Determination All measures have been taken to avoid and minimize potential impacts resulting from the proposed project (see BE). In consideration of the unlikely impact to ESA species as well as the proposed mitigation planting proposed in the BE, which will enhance the habitat, we determine that no -net -loss of ecological function will result from the repair of the existing bulkhead. Additionally we believe that this project reflects the goal of the Shoreline Master Program by balancing access to the environment with the protection of that environment. As mentioned above, a planting plan was submitted as mitigation in the BE and that will be included as mitigation for the bulkhead work also. There is an existing vegetation buffer along the shoreline at the site any vegetation disturbed by excavation for this project will be replaced on a one to one basis.

INTRODUCTION The purpose of this study and report is to present our findings, opinions, and conclusions regarding existing geotechnical conditions within the site. Specifically, we have evaluated the bulkhead which has had several failures and are providing a geotechnical engineering report discussing those conditions. The scope of our services includes surficial observations and assessment of the sloping areas. Using the data, we have listed our opinions and recommendations. Our scope of services includes the following: 1. Review geologic maps of the area and information in our files. 2. Perform a walk-through evaluation of existing geotechnical and relative stability conditions at the site. 3. Provide a geotechnical report discussing our findings, opinions, and recommendations as applicable to this project. EU: E APR 2 3 2015 CIfY OF 3?E N TON '! ANaNINC, r}IVISIQN F Geotechnical Engineed epoa� Decerchio Bulkhead Failure April 14, 2415 RMI File No. 69415 Page 2 SITE CONDITIONS Surface The site consists of an approximately 4 -foot tall rock bulkhead along the west and south sides of a residence located at 4005 Williams Avenue North. The site is bounded on the west by Lake Washington and on the south by the mouth of May Creek. Williams Avenue is east of the residence and another residence is situated north of the site. The rock bulkhead is founded on beach deposits, recent alluvium or artificial fill. The soil surface declines underwater gently to the west of the bulkhead. We also noted a failure about the middle of the west bulkhead and several areas where the bulkhead had lost fill and small rock along the bulkhead. We also noted that the face of the bulkhead lacks sufficient batter and there was no apparent drainage rock behind the bulkhead. Geoloo Most of the Puget Sound region was affected by past continental glaciations. The last period of glaciation, the Vashon Stade, ended approximately 10,000 to 11,000 years ago. Many of the geomorphic features seen today are a result of scouring and overriding by glacial ice. During the Vashon Stade, the Puget Sound region was overridden by over 3,000 feet of ice. Soil layers overridden by the ice sheet were compacted to a much greater extent than those that were not. A typical glacial sequence includes glacial till overlying advance outwash, underlain by transitional deposits and older non -glacial and glacial sediments. We reviewed the Geologic Map of King CountV, Washington, by Booth, D. B., Haugerud, R. A., and Sacket, J. (in press online, for the site geology. The site area has younger alluvium mapped along the west side of the mouth of May Creek with possible artificial fill mapped under the site. We also understand the site may have been constructed on fill placed over contaminated soil. RMI ASSOCIATES LLC Geotechnical Engineering Report Decerchio Bulkhead Failure April 14, 2015 RMI File No. 69415 Page 3 Explorations No subsurface explorations were performed_ We observed sands with gravel and pieces of rock derived from the failed rock bulkhead in exposures below the bulkhead face. This is consistent with recent beach deposits derived from younger alluvium or artificial fill. Observations We noted that in general the bulkhead is not performing well along most of its length. The failures appear to be due to the construction technique and materials used in construction of the bulkhead. Particularly we noted the quality of the rock used and the lack of batter in the construction. Recommendations We recommend that the bulkhead be reconstructed to improve the batter and replace any unsuitable rock. The rebuild should include drainage material and fabric behind the bulkhead to minimize the potential for piping and erosion behind the rock face. The planned construction should solve the issues that led to the failures. If you should have any questions, please don't hesitate to contact us. Ralph M.

The bulkhead is located both in the May Creek Reach A and the Lake Washington Reach C shoreline overlay areas. The project is a repair and maintanence of approximately 50 percent of the existing 4 -foot tall bulkhead piled rocks along 81 lineal feet of shoreline. Approximately 40 cubic yards of 4 to 6 -inch crushed rock and 40 cubic yards of 1 -inch minus crushed rock would be placed landward of the bulkhead to improve drainage and prevent future erosion of the soil. Approximately 40 cubic yards of 1 -inch minus spawning gravel is proposed waterward of the bulkhead. A silt curtain would be placed around the worksite. The applicant for the $32,000 project is also seeking authorization from Washington Department of Fish and Wildlife and Army Corps of Engineers. The submitted biological evaluation of impacts has made a determination of no - net -loss of ecological function. A planting mitigation plan was previously approved for a residential shared dock to be constructed on this subject site and the site to the north through LUA14-001181. A geotechnical report was submitted stating the problems identified with the existing wall that is falling into the lake in places and the erosion through the wall that is occurring.

Lake Washington is designated as Shorelines of Statewide Significance and May Creek is a regulated shoreline. Both are regulated by the City of Renton Shoreline Master Program. The proposed bulkhead repair work location is within the May Creek and Lake Washington shoreline jurisdiction. The Lake Washington shoreline at the site is classified as a "High Intensity Overlay District" and the May Creek shoreline is identified as "Urban Conservancy." A previous land use application for a shared boat lift was reviewed and approved for the subject site and northerly single-family neighbor through City file number LUA14-001811. The subject site contains a single-family residence at 4005 Williams Ave N, located in the Barbee Mill subdivision zoned R-10 (Exhibit 3). The site slopes towards the bulkhead and lake shoreline, with the steepest slopes approximately 40% (Exhibit 10). The project value is estimated at $32,000. The project work is proposed in the summer or fall 2015. The proposed project encompasses replacement of approximately 50% of the 6 -foot high piled rocks that run along 81 lineal feet of shoreline (Exhibit 4). The bulkhead would be repaired, as some areas have fallen into the lake and erosion from the uplands is occurring (Exhibit 5). Approximately 40 cubic yards of 4 to 6 - inch crushed rock and 40 cubic yards of 1 -inch minus crushed rock are proposed landward of the bulkhead, to improve drainage and prevent future erosion of the soil (Exhibit 5). The bulkhead design identifies the large boulder rocks atop a 6 -inch crushed rock base and the bottom of the rock bulkhead at two feet below the bottom surface of the lake (Exhibit 4). Approximately 40 cubic yards of 1 -inch minus spawning gravel is proposed waterward of the bulkhead (Exhibit 9). The size and type of rock that would be imported and used as replacement of smaller rock was not identified in the application materials. The submitted geotechnical evaluation states that the existing bulkhead has failed partly due to lack of batter/angle of the wall in addition to lack of construction technique and materials used previously (Exhibit 6). A geotech filter fabric is proposed between the uplands soil and crushed rock to prevent long-term erosion. For construction, a floating silt curtain is proposed to be placed around the work area to contain turbidity to the work area (Exhibit 6). The submitted Biological Evaluation/Lake and Stream Study/Habitat Data Report and Addendum (Exhibit 7), prepared by Marine Surveys & Assessments, dated August 25, 2014, has determined that no -net -loss of ecological function would result from the project's impacts with the previously approved shoreline plantings from the shared dock project (LUA14-001181). No comments were provided by reviewing agencies or from the general public. Beyond City of Renton approvals, the applicant would need to receive additional state and federal approvals, potentially including a Hydraulic Permit Approval (HPA) from state Department of Fish and Wildlife, federal Army Corps of Engineers approval, and potentially state Department of Natural Resources, as some of the bulkhead is outside the inner harbor line. Documentation of state and federal permits would be provided prior to building permit issuance.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The subject bulkhead along the Lake Washington shoreline is failing, where large bulkhead rocks are falling into the lake and erosion of upland soils are seeping through the wall (Exhibit 5). The subject bulkhead runs along much of the shoreline, along the westerly and City of Renton Department of Community & Economic Development Environmental Review Committee Report DICERCHIO SII4GLE-FAMILY BULKHEAD REPAIR LUA1S-000274, ECF, 5M Report of June 1, 2015 Page 4 of 7 southerly areas of the subject site. The proposed project requires restacking of existing rocks and addition of crushed rock behind the wail for support (Exhibit 9). Approximately 50% of the existing larger wall rocks are to be replaced with rocks brought from off-site. The type and size of rocks to be used as replacements are not identified in the submittal items. Therefore, staff will be recommending as a part of the SME that the applicant be required to provide a source statement of the large rocks to be used in the bulkhead repair. The statement shall be provided with type of rock and sizes as part of a City of Renton building permit submittal. The proposed building section of the bulkhead identifies crushed rock fill to be added at the back, or uplands, of the bulkhead and as a base (Exhibit 4). An approximate total of 80 cubic yards of crushed rock is proposed to be added uplands of the bulkhead. Approximately 40 cubic yards of 4 - to 6 -inch crushed rock and 40 cubic yards of 1 -inch minus crushed rock are proposed landward of the bulkhead to improve drainage and prevent future erosion of the soil (Exhibit 5). Waterward of the bulkhead, the applicant proposes approximately 40 cubic yards of 1 -inch minus spawning gravel. The area waterward of the bulkhead is outside of the Inner Harbor Line and within Washington Department of Natural Resources (DNR) owned property of Lake Washington (Exhibit 3). Work within DNR regulated areas requires coordination with the state agency. Therefore, staff will be recommending as a part of the SME that the applicant be required to contact DNR to receive permission to add spawning gravel to the lakebed where proposed. Approval from DNR shall be provided to the City of Renton prior to building permit issuance. The submitted Geotechnical Engineering Report, by RMI Associates, dated April 14, 2015, provides review of the existing and failing bulkhead wall and provides recommendations for repair of the wall (Exhibit 6). The geotechnical engineer states that the rock bulkhead failed in different areas where the bulkhead had lost fill and small rock along the bulkhead, and also notes that the face of the bulkhead lacks sufficient batter (angle) and there is no apparent drainage rock behind the bulkhead. The geotechnical evaluation states that in general the bulkhead is not performing well along most of its length and that the failures appear to be due to the construction technique and materials used in original construction. The engineer recommends that the bulkhead be reconstructed to improve the batter and replace any unsuitable rock, and that repair should include drainage material and fabric behind the bulkhead to minimize the potential for piping and erosion behind the rock face. Mitigation Measures: None Nexus: N/A 2. Water a. Wetland, Streams, Lakes Impacts: The project is proposed to occur in Lake Washington, beginning inside of the designated Inner Harbor and extending waterward outside of the Inner Harbor line (Exhibit 3) and ending in May Creek shoreline. There are two shoreline designations at the site, split between the Lake Washington "High Intensity Overlay District" and May Creek "Urban Conservancy Overlay District" (RMC 4-3-090G) (Exhibit 2). Lake Washington is a Shoreline of Statewide Significance and is included as a Shoreline of the State. As a Class 1 lake, it is a perennial salmonid -bearing body of water. May Creek is a City regulated shoreline. The applicant submitted a joint Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8), dated August 25, 2014, prepared by Marine Surveys & Assessments, for the previously ERC Report LUAIS-000274 DiCerchio Bulkhead Repair City of Renton Deportment of Community & Economic Development Environmental Review Committee Report DICERCHIO SINGLE-FAMILY BULKHEAD REPAIR LUA25-000274, ECF, SM Report of June 1, 2015 Page 5 of 7 applied for and approved shared dock (LUA14-001181). An Addendum to the evaluation was subsequently provided for the subject bulkhead work, by the same authors, dated April 10, 2015 (Exhibit 7). These documents conform to the requirements for Biological Evaluation/Lake and Stream Study/Habitat Data Report per RMC 4-8-120D. The original biological evaluation and addendum for the subject bulkhead project finds a no -net -loss of ecological function will result from this project. The addendum dated April 10, 2015 states that the new spawning gravel mix waterward of the bulkhead will improve the baseline habitat conditions. As part of the construction mitigation, the project narrative states that a floating silt curtain will be placed around the work area to contain turbidity during the repairs. Therefore, staff recommends that a floating silt curtain be a requirement of the construction phase and that the curtain remain in place until repair and maintenance activities are completed. Mitigation Measures: None Nexus: N/A 3. Vegetation Impacts: The submitted original Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) provides background of the redevelopment of the Barbee Mill community where upland restoration of the overall Barbee Mill site involved removal of fill soils behind the bulkhead, along with asphalt, a pier, wooden bulkhead and pilings associated with the previous industrial mill operation. Extensive shoreline restoration was completed, although the subject properties are located south of the extensive remediation that occurred. As part of site redevelopment, a planted buffer along the shoreline of approximately 35 feet was required along the Lake Washington shoreline of the Barbee Mill subdivision. The applicant does not propose any new plantings beyond those that have been required for the 35 -foot planted buffer and plantings as mitigation for the new shared moorage pier (as required through the approval for LUA14-001181). The applicant identifies that any removed soils or vegetation that occurs as part of the bulkhead work would be replaced (Exhibit 9). Staff recommends that the applicant be required to replace any upland vegetation removed or damaged as part of the bulkhead repair. The replaced plantings shall be equal to or better than existing conditions. The applicant did not provide a construction mitigation plan, as such staff is not able to identify if there would be impacts to existing vegetation due to deliver of rocks for the bulkhead. Therefore, staff recommends that the applicant be required to provide a construction mitigation plan with the hours of work, path to bulkhead, and locations on the subject site or other areas nearby that may be impacted. Mitigation for these impacts should be provided with the plan. Mitigation Measures: 1. The applicant shall improve any surface soils or vegetation uplands of the bulkhead that are removed or damaged as part of the bulkhead repair to existing or better conditions. A replacement plant pian shall be provided to the Current Planning Project Manager for review and approval prior to building permit issuance. 2. The applicant shall provide a construction mitigation plan with the hours of work and locations on the subject site that may be impacted. A mitigation plan or replanting plan shall be provided to the Current Planning Project Manager for review and approval prior to building permit issuances, for any areas identified to be impacted.

Wildlife Impacts: The Biological Evaluation/Lake and Stream Study/Habitat Data Report and Addendum submitted for the proposed project includes analysis of birds, mammals, and fish in the evaluation. The study states that the only wild mammals reported as observed in the general area are deer. The following bird species observed on or near the project site: hawks, herons, eagles, quail, osprey, cormorants and songbirds. The original Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) study states that bald eagles are no longer on the list of threatened or endangered species under the Endangered Species Act but continue to be protected by the Bald and Golden Eagles Protection Act and the Migratory Bird Treaty Act are protected as a "sensitive species" in Washington State. Sensitive species are vulnerable or declining and likely to become endangered or threatened in a significant portion of their range within the state without cooperative management or removal of threats. In addition, the Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) indicates that salmonids observed at the site include salmon and trout. Salmonids known to be present in southern Lake Washington include Puget Sound Chinook salmon, Coho salmon, sockeye salmon, steelhead trout, bull trout and cutthroat trout. Puget Sound Chinook, Puget Sound steelhead and bull trout are all listed as threatened under the Endangered Species Act (ESA). Previous shoreline remediation accomplished in conjunction with the development of the plat was designed to be consistent with Water Resource Inventory Area (WRIA) 8 Conservation Plan recommendations. As a result of remediation, shoreline that was previously unsuitable habitat for fish and other aquatic life due to extensive shoreline modifications and industrial use of the site has been restored. The Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) and Addendum to the Report (Exhibit 7) provide evaluation of the specific species and habitat protected by federal jurisdiction, including Puget Sound Chinook, Buil Trout, Puget Sound Steelhead, and Marbeled Murrelets. The Murrelets are unlikely to be present in the project vicinity according to the study due to there not being a nesting area nearby and that the area is highly urbanized and within close proximity of a major highway corridor. The proposed bulkhead construction sequencing and mitigation proposed by the applicant would include the installation of a silt curtain. The silt curtain should minimize impacts to fish species as a result of activities associated with the proposed project. If at any time, as a result of project activities, fish are observed in distress, a fish kill occurs, or water quality problems develop (including equipment leaks or spills), operations shall immediately cease and the Washington Department of Fish and Wildlife (WDFW) and the Washington Department of Ecology shall be contacted immediately. Work shall not resume until further approval is given by the WDFW. The Washington Department of Fish and Wildlife has established a construction window for this portion of Lake Washington. The construction window allows for overwater construction to occur only between July 16 and December 31. Therefore, staff will be recommending as a part of the SME that the applicant be required to adhere to this established in -water construction window. Construction shall take place only during the Department of Fish and Wildlife approved in -water construction window from July 16 through December 31, unless approved otherwise by Department of Fish and Wildlife.

INTRODUCTION The purpose of this study and report is to present our findings, opinions, and conclusions regarding existing geotechnical conditions within the site. Specifically, we have evaluated the bulkhead which has had several failures and are providing a geotechnical engineering report discussing those conditions. The scope of our services includes surficial observations and assessment of the sloping areas. Using the data, we have listed our opinions and recommendations. Our scope of services includes the following: 1. Review geologic maps of the area and information in our files. 2. Perform a walk-through evaluation of existing geotechnical and relative stability conditions at the site. 3. Provide a geotechnical report discussing our findings, opinions, and recommendations as applicable to this project.

The site is bounded on the west by Lake Washington and on the south by the mouth of May Creek. Williams Avenue is east of the residence and another residence is situated north of the site. The rock bulkhead is founded on beach deposits, recent alluvium or artificial fill. The soil surface declines underwater gently to the west of the bulkhead. We also noted a failure about the middle of the west bulkhead and several areas where the bulkhead had lost fill and small rock along the bulkhead. We also noted that the face of the bulkhead lacks sufficient batter and there was no apparent drainage rock behind the bulkhead. Geolog Most of the Puget Sound region was affected by past continental glaciations. The last period of glaciation, the Vashon Stade, ended approximately 10,000 to 11,000 years ago. Many of the geomorphic features seen today are a result of scouring and overriding by glacial ice. During the Vashon Stade, the Puget Sound region was overridden by over 3,000 feet of ice. Soil layers overridden by the ice sheet were compacted to a much greater extent than those that were not. A typical glacial sequence includes glacial till overlying advance outwash, underlain by transitional deposits and older non -glacial and glacial sediments. We reviewed the Geoloclic Map of King County,Washin ton, by Booth, D. B., Haugerud, R. A., and Sacket, J. (in press online, for the site geology. The site area has younger alluvium mapped along the west side of the mouth of May Creek with possible artificial fill mapped under the site. We also understand the site may have been constructed on fill placed over contaminated soil.

ADDENDUM: Addition of Proposed Repair of Existing Bulkhead April 101 2015 For: DiCerchio/ Barbee Mill Waterfront LLC Joint -Use Pier Project 4005 Williams Ave. N. Renton, WA 45056 Case ## , Biological Evaluation Dated August 25`b9 2014 To: Whom it may concern, Please accept this addendum letter for the addition of the repair of an existin� bulkhead to the original Biological Evaluation for the DiCerchio Pier, Ramp, and Float project dated August 25 , 2014. This letter describes the nature of the additional project component, addresses any potential impacts of this addition as well as provides an impact determination and net -loss analysis. A. Project Description The proponents are proposing to repair an existing bulkhead at the Dicerchio site (see Figures 1-3). The repair will consist Of restacking rocks and installing crushed rock drainage material landward of the existing bulkhead. It is estimated that approximately 50% plus or minus of the existing bulkhead rocks will be replaced with new rocks. Forty cubic yards of 4" to 6" crushed rock and 40 cubic yards of minus crushed rock will be added landward of the bulkhead for drainage material. In addition, 40 cubic yards of spawning gavel mix will be added waterward of the repaired bulkhead as mitigation. B. Impacts of the Project The proposed project is a bulkhead repair project, not a new bulkhead project. Therefore, there will be no change in the baseline habitat conditions. In fact, the addition of the spawning gravel mix will actually improve the baseline habitat conditions. C. Net -Loss Determination All measures have been taken to avoid and minimize potential impacts resulting from the proposed project (see BE). In consideration of the unlikely impact to ESA species as well as the proposed mitigation planting proposed in the BE, which will enhance the habitat, we determine that no -net -loss of ecological function will result from the repair of the existing bulkhead. Additionally we believe that this project reflects the goal of the Shoreline Master Program by balancing access to the environment with the protection of that environment. As mentioned above, a planting plan was submitted as mitigation in the BE and that will be included as mitigation for the bulkhead work also. There is an existing vegetation buffer along the shoreline at the site any vegetation disturbed by excavation for this project will be replaced on a one to one basis. EC."

PROJECT DESCRIPTION A. Project Location: '/a Section NW32, Township 24N, Range 05E. 4005 and 4011 Williams Avenue N Renton, WA 98056 Latitude: 47.52848° N Longitude: 122.20532°W See Figure 1 for project location. B. Site Description: The proposed project is a joint -use pier to be located along the common property line between two abutting lots, 4005 and 4011 Williams Ave N, Renton, WA 98056 (jointly the "subject property"), presently owned by Richard DiCerchio and Barbee Mill Waterfront LLC, respectively, (jointly the "applicant" for the requested shoreline substantial development permit). The properties are located within the Barbee Mill Community, a major waterfront subdivision. The subject property is located along the eastern shore of Lake Washington in the City of Renton (Figure 2). The proposed joint -use pier would provide moorage and facilitate access to Lake Washington for residents of the subject property and their guests. Two bodies of water are adjacent to, or flow through, the Barbee Mill Community: Lake Washington and May Creek. The subject property is located along Lake Washington, a Shoreline of Statewide Significance as provided in RMC 4-3-090F1, and a Shoreline of the State under RMC 4-11-190. This Lake Study is prepared in accordance with the requirements of RMC 4-8-120D with respect to the Lake Washington shoreline of the subject property. May Creek, a Shoreline of the State (RMC 4-3-090F2), flows through the Barbee Mill Community. The May Creek open space (a riparian buffer) and a street are located between the two lots and May Creek. The Barbee Mill Community is located on the approximately 22 acre site of the former Barbee Mill Company lumber mill. The Barbee Mill Community has 114 multi -story paired homes, a pond, walking trails and lakefront open space for the use of residents. Lots 23 through 48 are lakefront lots. To restore the former industrial site to a parcel suitable for a residential waterfront subdivision, the mill buildings were demolished; fill soils were removed from behind the bulkhead; asphalt paving, a pier, the wooden bulkhead and piling associated with the mill operation were removed; and extensive shoreline restoration was completed. The subject property is located south of, and was not included in, this extensive remediation. A concrete bulkhead is located along most of the Barbee Mill Waterfront LLC parcel; a rock bulkhead is located along the DiCerchio parcel. The substrate immediately waterward of the property consists of large and small cobble. A number of factors were considered in determining the location of the proposed pier, most importantly the lower environmental impact of a joint -use structure over individual single -property use piers. In establishing design parameters for the proposed joint -use pier, it was required that it not interfere with the general public's use and enjoyment of Lake Washington, that it not pose a navigation hazard to boaters, and that it not interfere with the use of existing or future neighboring docks or piers. C. Lake and Stream Classifications: As mentioned above, as a Shoreline of Statewide Significance (RMC 4-3-090F1), Lake Washington is included in the definition of a Shoreline of the State (RMC 4-11-190). Lake Washington is a Class 1 lake as it is a perennial salmonid -bearing body of water classified as a Shoreline of the State (RMC 4-11-19051). May Creek is an M, c&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project- 3 r IT a R important salmonid stream that is classified by the City of Renton and the State of Washington as Class 1 waters and included within the definition of a Shoreline of the State (RMC 4-3-090F2). D. Shoreline Restoration: Prior to restoration of the beach in conjunction with vacation of the land, the Lake Washington shoreline north of the subject property was heavily bulkheaded, back-filled and covered with impervious asphalt paving; numerous piling and substantial quantities of concrete rubble and other shoreline debris were on the site. Pursuant to the general development site remediation, upland and in -water structures including the timber bulkhead and piling were removed, shoreline rubble was removed, fill soil was excavated to subgrade elevations, toe rock and a temporary quarry spall erosion control berm were installed, and sand, gravel and rock materials were used to construct a beach to mimic natural conditions. Although the area of extensive remediation did not encompass the subject property, a planting buffer of native vegetation (Figure 6 and 7) was installed along all the lakefront lots, including the subject property, to environmentally and functionally enhance the entire development shoreline. The Ordinary High Water (OHW) mark for Lake Washington is the line of mean high water (RMC 4-11-150 Definitions 0). The Lake Washington water depth is controlled by the Army Corps of Engineers at the Hiram M. Chittenden Locks and is at 21.8' of lake elevation. In the course of the Barbee Mill Beach Restoration site remediation, permanent toe rock was installed along the OHW line. As of March 20, 2007, the date a SCUBA survey was conducted for purposes of identifying flora, fauna, substrate types and other qualitative information relative to the Biological Evaluation prepared for the previous community dock project, coir rolls were located along the OHW line within the remediation area. The May Creek OHW mark is the mean high water line of the stream (RMC 4-11-150 Definition O). E. Vegetative Cover of the Site: The study area includes no wetland or flood hazard areas; it does include Lake Washington riparian areas. Prior to the Barbee Mill Beach Restoration project, riparian vegetation was found to be generally absent within the study area as the shoreline behind the bulkhead was paved. In unpaved areas, vegetation noted included Juncus effusus (soft rush) and Iris pseudocaris (a non-native iris). The upland redevelopment required extensive regrading and clearing; a mitigation planting plan was agreed upon that includes planting along the Lake Washington shoreline. In accordance with this mitigation plan, plantings on the subject property have been installed (Figures 6 and 7). In conjunction with construction of the proposed joint -use pier, 22 additional native shrubs will be planted. The planting plan details will be shown on the full size drawings. F. Ecological Functions of lake Washington along the Study Area: Previously to the Barbee Mill Community development, the industrial structures and use of the site limited the ecological functions that would otherwise have been provided by Lake Washington and its adjacent riparian area. As a result of the extensive general site restoration work completed north of the subject property, the ecological functions of the portion of the lake within the study area should be greatly enhanced. Previously planted riparian vegetation and additional plantings in conjunction with the proposed joint -use pie project will further assist in restoring the ecological functions of Lake Washington. Much of this new vegetation will be overhanging, providing shade and predator protection for fish and aquatic invertebrates. The newly planted riparian vegetation will add significant organic matter to the lake substrate in the form of leaves and woody debris that fall and wash into the lake. This will provide additional source of food, shelter and shade for aquatic invertebrates and fish. This increased vegetation will also provide food and shelter for terrestrial insects, and in turn provide an additional food source for birds and animals that feed upon them. The addition of riparian vegetation to this formerly near -barren site should also help water quality by filtering pollutants, removing nutrients and reducing sediments in any runoff from the adjacent upland development. The increased overhanging vegetation should facilitate the migration of juvenile salmon. MS&A DiCerchio%Barbee Mill Waterfront LLC Joint -Use Pier Project- 4 G. Fish and Wildlife Use or the Area: Birds: Birds observed on or near the site include hawks, herons, eagles, quail, osprey, cormorants and songbirds. Before the mill structures were demolished, an osprey nest was successfully relocated from the top of the old mill sawdust collector to a platform built on a 25' pole over the water not far from the original nest site. The osprey have accepted the new nest and a video camera records their activities for viewing over the Internet. Protected wildlife in Washington State shall not be hunted or fished (WAC 232-12-011). Protected wildlife noted from time to time within the general Barbee Mill Community development area includes the marbled murrelet and the bald eagle. The marbled murrelet is classified as a "threatened species," a species likely to become endangered within the foreseeable future throughout a significant portion of their range within the state without cooperative management or removal of threats. The bald eagle is no longer on the list of threatened or endangered species under the Endangered Species Act (ESA) but continues to be protected by the Bald and Golden Eagles Protection Act and the Migratory Bird Treaty Act and is protected as a "sensitive species" in Washington. Sensitive species are vulnerable or declining and likely to become endangered or threatened in a significant portion of their range within the state without cooperative management or removal of threats. Mammals: The only wild mammals reported as observed in the area are deer. Fish: Salmonids observed at the site include salmon and trout. Salmonids known to be present in southern Lake Washington include Puget Sound chinook salmon, coho salmon, sockeye salmon, steelhead trout, bull trout and cutthroat trout. Puget Sound chinook, Puget Sound steelhead and bull trout are all listed as threatened under the ESA. Other fish observed at the site include bass, black crappie, bluegill, pumpkinseed sunfish, tench and yellow perch. The shoreline remediation was designed to be consistent with Water Resource Inventory Area (WRIA) 8 Conservation Plan recommendations. As a result of the remediation, shoreline that was previously unsuitable habitat for fish and other aquatic life due to extensive shoreline modifications and industrial use of the site has been restored. The restored gravel substrate and gently sloping bottom should provide favorable habitat for winter rearing of salmon fry. The new gravel and cobble substrate to the north and the existing cobble on the subject property should be suitable habitat for benthic invertebrates which would likely attract juvenile salmonids. H. Project Details: .The pier will be supported by two 10" diameter, four 8" diameter and two 4" diameter galvanized steel piles. It will have a 4' by 40' walkway from shore and a b' by 40' walkway for a total length of 80' from the OH WM. Two free standing boat lifts will be installed at the pier. A 30' by 10.5' translucent canopy will be installed over one boat lift. Two 12" diameter steel mooring piles will be installed adjacent to the pier (Figures 3-5). I. Construction Sequence: 1. Mobilize construction barge to the site with all construction materials and equipment on board. Moor the barge as to prevent grounding on the lake bottom at any time during construction. 2. Install silt containment curtain around work area to contain any debris that may fall into lake waters. In the event any materials enter lake waters they will be retrieved immediately and placed in debris containers on the barge. 3. Using the barge -based crane and vibratory insertion/extraction system, install (2) at 12" diameter, (2) at 10" diameter, (4) at 8" diameter and (2) at 4" diameter galvanized steel piles to practical refusal. 4. Cut steel piling as necessary at the appropriate elevation. 5. Install pre -fabricated cap brackets to piling. Connect wood framing to cap brackets using hand tools. Install grated decking on pier. b. Set boat lifts in place using crane on the barge. The translucent boat canopy will be installed by hand. MS&A DiCerchic/Barbee Mill Waterfront LLC Joint -Use Pier Project- 5 a ■ MS&A 7. Demobilize and dispose of all debris at approved upland disposal site. General Notes: I. All treatments will be applied and fully cured prior to delivery to the site. J. Action Area: The action area should include the area within a one -mile radius of the project location. This area includes potential turbidity and noise impacts from the construction process. II. SPECIES AND HABITAT INFORMATION A. Species information: In the project area, the Puget Sound chinook (Oncorhynehus tshawytscha) is listed under the Endangered Species Act as a threatened species according to the National Marine Fisheries Service (NMFS) (Federal Register, Vol. 64, No. 56). On May 11, 2007, NMFS also listed the Puget Sound steelhead (Oncorhynchus mykiss) as a threatened species under the ESA (Federal Register/ Vol. 72, No. 91 / Friday, May 11, 20071 Rules and Regulations). Bull trout (Sulvelinus confluentus) were listed as threatened by the United States Fish and Wildlife Service (USFWS) in October of 1999. On September 2, 2005, NMFS issued the final rule designating critical habitat for 12 Evolutionarily Significant Units (ESUs) of West Coast salmon, including the Puget Sound Chinook Salmon ESU and the Hood Canal Summer -run Chum ESU. The project site is in an area designated as critical habitat for the Puget Sound Chinook ESU (Federal Register / Vol 70, No. 1701 Friday, September 2, 2005 Rules and Regulations). USFWS has designated critical habitat in Lake Washington for Coastal -Puget Sound bull trout (Federal Register / Vol. 70, No. 185 / September 26, 2005 / Rules and Regulations). Puget Sound Chinook: Puget Sound chinook, also called the king salmon, are distinguished from all other Pacific salmon by their large size. Most chinook in the Puget Sound are "ocean -type" and migrate to the marine environment during their first year (Myers et al. 1998). They may enter estuaries immediately after emergence as fry from March to May at a length of 40 mm., or they may enter the estuaries as fingerling smolts during May and June of their first year at a length of 60-80 mm. (Healey 1982). Chinook fry in Washington estuaries feed on emergent insects and epibenthic crustaceans (gammarid amphipods, mysids, and cumaceans). As they grow and move into neritic habitats, they feed on decapod larvae, larval and juvenile fish, drift insects, and cuphausiids (Simenstad et al. 1982). These ocean -type chinook use estuaries as rearing areas and are the most dependent of all salmon species on estuaries for survival. In the Lake Washington system, adult chinook salmon usually arrive at the Chittenden Locks in July, although there are some arrivals before and after July (Synthesis of Salmon Research and Monitoring. 2008). According to Fresh et al. (2000), the total time for salmon migration from the Locks to arrival at their tributary spawning grounds "can take up to 55 days, but averages less than 30." During much of this time, salmon hold in the upstream area from the Locks before moving through the Ship Canal and Lake Union. Fresh et al. (2000) found the average holding time to be from 17 to 19 days. After reach their spawning streams between September and November, spawning occurs from October to December. According to Tabor et al. (2006), "Fry emerge from their redds from January to March. Juvenile Chinook salmon appear to have two rearing strategies. rear in the river and then emigrate in May or June as pre-smolts, or emigrate as fry in January, February, or March and rear in the south end of Lake Washington or Lake Sammamish for three to five months." In the project area vicinity, juvenile chinook salmon from the Cedar River enter Lake Washington and rear in the south end of the lake primarily from January to May. DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project• 6 Tabor et at. (2006) also reported that: Similar to results of 2002, juvenile Chinook salmon were concentrated in the south end of Lake Washington from February to May.....Therefore, it appears that the lake shore area near the natal stream is an important nursery area for juvenile Chinook salmon. In Lake Washington, the major part of this nursery area appears to be roughly from Pritchard Beach on the west shoreline and the mouth of May Creek on the east shore and the south part of Mercer Island. The distance from the mouth of the Cedar River to the edge of the nursery area is around 6 km. north of this area; the number of Chinook salmon would be expected to be relatively low until mid-May or June. In the sante study cited above, it was found that marked Chinook did not move far from their release site at Gene Coulon Park (approximately 1.5 miles south of the current project site). Marked juveniles were observed 1, 7, 15, and 21 days after release at Gene Coulon Park. All of the marked salmon that the investigators observed had moved less than 150 m from their release site at the park. After moving slowly away from the Green River and south Lake Washington, juveniles reach the Chittenden Locks during the period between May and August, with peak migration through the Locks taking place in June. According to Kerwin (2001) chinook, coho, sockeye and winter steelhead use May Creek for spawning, rearing and migration. However, volunteers from the Volunteer Salmon Watchers Program have been observing salmon in May Creek since 2000. They have reported that only sockeye are seen consistently, while chinook, coho, cutthroat trout and kokanee salmon are less commonly seen. Hammer (2011) reported that the number of chinook varies from 0 to 12 fish annually in May Creek. WDFW reported three live chinook and one redd in 2010 spawner surveys. Bull Trout: Coastal -Puget Sound bull trout have ranged geographically from northern California (at present they are extinct in California) to the Bering Sea coast of Alaska, and northwest along the Pacific Rim to northern Japan and Korea. Bull trout are members of the char subgroup of the salmon family. Spawning occurs typically from August to November in streams and migration to the open sea (for anadromous populations) takes place in the spring. Eggs and juveniles require extremely cold water for survival. Temperatures in excess of about 15 degrees C are thought to limit bull trout distribution (Rieman and McIntyre 1993). They live both in fresh and marine waters. Some migrate to larger rivers (fluvial), lakes (adfluvial), or saltwater (anadromous) before returning to smaller streams to spawn. Others (resident bull trout) complete all of their life in the streams where they were reared. Habitat degradation, dams and diversions, and predation by non-native fish threaten the Coastal -Puget Sound population. The Coastal -Puget Sound bull trout population is thought to contain the only anadromous forms of bull trout in the contiguous United States (Federal Register, Vol. 64, No. 210, 1999). Two subpopulations of bull trout (also known as "native char") are considered within the Lake Washington area: the Chester Morse Reservoir population and the Issaquah Creek-Sammamish River population (Federal Register, Vol. 64, No. 210, 1999). "Only two `native char' have been observed during the past 10 years in the Issaquah Creek drainage and none have been observed in the Sammamish River system. It is questionable whether a viable subpopulation remains." (Federal Register, Vol. 64, No. 210, 1999). Puget Sound Steelhead: Wild winter steelhead enter the Lake Washington system in mid-December with peak spawning taking place in May. There have been high rates of predation by California sea lions at the Ballard Locks, which is one of the leading factors in the declining steelhead production in the Lake Washington system (1992 Washington State Salmon and Steelhead Stock Inventory. Appendix One - Puget Sound Stocks. Washington Department of Fish and Wildlife, Olympia, WA.). According to Kerwin (2001): The Lake Washington system supports one native winter steelhead stock but not a summer steelhead stock (SASSI 1994). The winter steelhead stock was listed in SASSI as "Depressed" but has recently shown some evidence of rebounding. A limited hatchery program utilizing the native winter steelhead stock was initiated in 1997 as a supplementation type program to assist in recovery of winter steelhead populations in the north Lake Washington tributaries. The sharp decline in Lake Washington winter steelhead was noted MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Her Project• 7 as a reason for concern by NMFS in their stock status review (Busby 1996). However, in a more recent analysis, between 1986 and 2004 escapement for the Lake Washington winter -run steeihead ranged from 1,816 (1986) to 44 (2004) (WDFW 2004). Based on the chronically low escapement and short-term severe decline in escapements, the stock status has decreased from its 1992 "depressed" status to "critical" in 2002. WDFW has reported steeihead in the lower 3 miles of May Creek (Salmon Scape, 20I0). Marbled Murrelets: Marbled murrelets are small marine birds in the alcidae family. They spend most of their time at sea and only use old growth areas for nesting. In the critical nesting areas, fragmentation and loss of old growth forest has a significant impact on the survival and conservation of the species (WDW, 1993). Adult birds are found within or adjacent to the marine environment where they dive for sand lance, sea perch, Pacific herring, surf smelt and other small schooling fish, and feed on invertebrates. The project site is located in an urban environment adjacent to a major highway. There is a high level of ambient noise in the project vicinity. There is no nesting habitat near the site. Therefore, it is unlikely that murrelets will be present in the project vicinity. III. EFFECTS OF THE ACTION The status of each of the listed species in the action area has been provided. The proposed project has been described and the action area defined. When reviewing all the data, the potential direct and indirect effects of the proposed action on the listed species and their critical habitat should be considered. A. Direct Effects: When considering the direct effects of the proposed project, one must determine if the proposed project will immediately reduce or destroy the listed species and/or their habitat. The potential, direct impacts caused by the construction process include increased noise and turbidity. Pile driving noise: A vibratory pile driver will be used to drive the piles to practical refusal. Feist et al. (1992) reported that salmonids could be expected to hear pile driving noise approximately 2,000' from the source. Based on the studies at the Everett Homeport, these researchers concluded that pile driving did alter the distribution and behavior of juvenile pink and chum salmon. However, the Everett Homeport results may not be entirely applicable to the proposed project, because a diesel powered compression hammer was used in that study. As stated in the Feist report, "It would be reasonable to say that juvenile salmonids might respond differently to the sounds of a vibratory hammer, compared to that of a diesel compression hammer." As noted above, it is unlikely that murrelets will be present in the action area. Therefore, the construction process should have little or no impact on marbled murrelets. Turbidity: Increased turbidity caused by pile driving could, under certain circumstances, have adverse effects on salmon and bull trout. The effects depend on duration of exposure, concentration of turbidity and the life stage of the salmon during the increased exposure. The effects can be discussed in terms of lethal, sublethal or behavioral (Nightingale and Simenstad 2001 a and Simenstad, editor, 1988). A silt containment curtain will be installed in the project area to contain and minimize turbidity impacts. To minimize the adverse effects of increased turbidity and noise on migrating salmonids and bull trout, inwater construction work will take place during the approved work window from July 16 to December 31. Overwater work can proceed outside of the inwater work window. MS&A DiCerch io/ Barbee Mill Waterfront LLC Joint -Use Pier Project- 8 � � s B. Indirect Effects: Indirect effects are effects of the project that occur later in time. For this project, indirect effects might include alteration of juvenile salmon migratory pathways, increase in salmonid predation and reduction in prey resources and refugia due to shading of the epibenthic substrate by the structure. Migratory pathway alteration: Freshwater: There were no studies specifically investigating the effects of piers on salmonid migration in lakes cited by Kahler et al. (2000) in their review of pier -related impacts in lakes. Concerning the lake environment, Kahler et al. (2000) state, "The question remains whether juvenile salmonids in lakes migrate under, or otherwise utilize, piers, or if they avoid them and/or traverse their perimeter." However, more recent reports have provided additional information concerning salmon responses to overwater structures. Tabor and Piaskowski (2002) noted that, "In February and March, Chinook salmon were found using overhead structures (piers, docks, and overhanging vegetation) during the day but in April and May, no chinook salmon were ever observed using overhead structures. At night, chinook salmon rarely used overhead structures." The authors hypothesized that the overhead structures were being used as a substitute for natural overhead cover during the days in February and March. In a later study, Tabor et al. (2006) noted slightly different results. They state that, "When migrating Chinook salmon approach a pier they appeared to move to slightly deeper water and either pass directly under the structure or swim around the pier. Most likely they move to deeper water as a way of reducing their predation risk." The pier where these findings we made is approximately 7.8' wide, 138' long and had solid decking. The dimensions of the piers in the earlier study are not known. The results from the later study were noted in May and July, whereas the 2002 study results were for the earlier months of February and March. In a later study, Tabor et al. (201 I) reported that, "Juvenile Chinook salmon were rarely observed under an overwater structure during either daytime or nighttime." There were no details concerning the type of overwater structure where these observations were made -- sold decking or grated overwater structures. The results of Celedonia et al. (2008) were similar to those of Tabor et al. (2000). Celedonia et al. stated, "Juvenile Chinook salmon generally avoided areas directly beneath overwater structures. However, areas along the edges of structures (within about 2 m horizontal distance) were sometimes used for prolonged periods (up to 2 hours in one case)." However, these authors offered the following qualifying statement: These observations may be representative of holding fish near structures in general, but may not be an accurate indication of how untagged Chinook salmon would generally behave upon volitionally entering these specific areas. Actively migrating fish (i.e., most fish released off-site and observed at the Seattle Tennis Club site) often appeared to change course as they approached a structure. Structure width and water depth appeared to influence degree of avoidance. Fish appeared less hesitant to pass beneath narrow structures. Fish also appeared to move into deeper water to travel beneath or around structures. These authors also observed: Behavior at structures differed (i.e., swim beneath or travel around perimeter), and may have been related to such interrelated factors as: fish size, light levels beneath the structure, degree of contrast at the light - dark edge, width of the structure, height of the structure above the water surface, and water column depth beneath the structure. Further study is needed to conclusively determine how these and other factors interact to influence Chinook salmon behavior. Marine Waters: In the marine environment, it is generally accepted that overwater structures can alter migration behavior of juvenile salmon (though the effects may vary depending on the design and orientation of the structure, degree of shading, and the presence of artificial light), and reduce salmon prey resources and refugia by shading aquatic plant life (Simenstad et al. 1999; Nightingale and Simenstad 2001b). However, the r ,)&A DIC erchio/Barbee Mill Waterfront LLC Joint -Use Pier Project* 9 significance of these effects is not clear. As Simenstad et al. state, "We found no studies that described empirical evidence supporting or refuting that modification of juvenile salmon behavior in shoreline habitats was reflected in changes in survival." Nightingale and Simenstad (2001 b) state, "Presently, although we know that under some conditions small juvenile salmon will delay or otherwise alter their shoreline movements when encountering an overwater structure, the conditions under which this behavioral modification is significant to the fishes' fitness and survival is relatively unknown." A study by Williams et al. (2003) at the Mukilteo ferry terminal, found that, "Salmon fry were observed in all nearshore habitats during each transect sampling period (day and night). The fry were observed under a wide range of PAR values (0.0 pmol m-2 s-1 to 2370 pmol m-2 s-1). Fry were observed both outside the terminal and underneath the terminal at all times, and shadows produced by the 10 -m -wide terminal structure did not appear to act as barriers to fry movement at this location." There is no question that underwater structures may alter migration patterns —that is not in dispute. As seen in the study by Williams and in many other studies (see the literature review by Weitkamp - 2003), there are studies that indicate that salmon migration is not affected by the presence of overwater structures. Of course, there are other studies indicating migration patterns are altered by overwater structures. The issue is that no one has shown that these migration changes lead to increased mortality or decreased fitness. None of the studies that report changes in salmonid migration patterns caused by overwater structures in the marine environment have reported that these changes have a negative impact on salmonids. Increased predation: An additional concern about the impacts of overwater structures on migrating salmon is that they will be forced to move out into deeper water, where they will be consumed by predatory fish species. However, in a study conducted in the marine environment, Williams et al. (2003) noted: We found no evidence that avian, marine mammal, or fish predators consumed more juvenile salmon near WSF terminals than along shorelines without overwater structures. Few species appeared to be targeting abundant fry in nearshore habitats, and we observed only two occasions in which predators (one tern sp., one staghorn sculpin) had consumed juvenile salmon. The authors also state, Our analysis of fish diets at the Mukilteo ferry terminal provides one piece of conclusive evidence that juvenile salmon were not a major dietary component of predatory fish species during our study. It should be noted that the Williams study was conducted in the marine, not lake, environment. In Lake Washington, smallmouth bass migration into the littoral zone corresponds with the peak occurrence of migrating salmonids in this zone (Fresh et al. 2001). Because of these similar migration patterns, salmonids are most at risk of predation from smallmouth bass in Lake Washington. Bass prefer complex, natural cover for their foraging environment. When there is a scarcity of natural cover for foraging, as is the situation in Lake Washington, they tend to use the dominant structures in the environment, such as pilings and piers, for foraging cover (Kahler et al. 2000). There is concern that increasing the number of overwater structures will increase the predation success of smallmouth bass on migrating salmonids. Tabor et al. (2004) investigated predation of juvenile Chinook salmon in three areas of the Lake Washington Basin. One of the areas they looked at was the south end of Lake Washington, an important rearing area. The investigators found that: The only predators observed to consume Chinook salmon were cutthroat trout, prickly sculpin (C. Asper), smallmouth bass (Micropterus dolomieui), and largemouth bass (M salmoides). Consumption of Chinook salmon by cutthroat trout was observed in February, March and early April. Predation by prickly sculpin was only observed in February. Smallmouth bass consumed Chinook salmon in May and June. Few largemouth bass were collected; however, we did document a largemouth bass that had consumed a Chinook salmon in June. We estimated a total of 1,400 Chinook salmon fry were consumed by littoral predators from February to mid May..... Based on consumption estimates and expected abundance of juvenile Chinook salmon, predatory fishes probably consumed less than 10% of the fry that entered the MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project• 10 lake from the Cedar River. The investigators in this study did not comment on the impacts of overwater structures on the predation rate found in south Lake Washington. C. Interrelated/interdependent Effects: Completion of this project will not promote fixture construction or other activities that would not otherwise occur without its completion. Therefore, no additional interrelated or interdependent actions that could affect species regulated under ESA will occur because of this project. D. Take Analysis: "Take" is defined as, "to harass, harm, pursue, hunt, shoot, wound, trap, capture, collect or attempt to engage in any such conduct." The USFWS further defines "harm" as "significant habitat modification or degradation that results in death or injury to listed species by significantly impairing behavioral patterns such as breeding, feeding, or sheltering." It is likely that no "take" will result from this project. E. Conservation Measures: In order to minimize any direct effects on the listed species caused by this project, inwater work should take place between July 16 and December 31. It is requested that overwater work be allowed to take place outside of this work window. Additional impact reduction and mitigation measures will reduce adverse impacts of the project. They include: 1. The first 40' of the fully grated pier will only be 4 -feet wide. 2. Only two 4" diameter steel pilings will be used to support the first 41' of the pier to minimize migration obstacles for young salmonids that prefer the more shallow areas. 3. The construction barge will not be allowed to around out on the lake bottom at anytime. 4. Piles will be driven using a vibratory pile driver to practical refusal. 5. Construction will take place during authorized in water work windows designed to protect listed species and/or critical habitat. 6. Twent-two shrubs will be planted in addition to the existing native plants seen in Figures 6 and 7. F. Determination of Effect: After reviewing the appropriate data and surveys, the effect determinations for the impacts of the project, as designed, are: L Puget Sound chinook —"May affect, not likely to adversely affect" 2. Bull trout —"May affect, not likely to adversely affect" 3. Puget Sound steelhead —"May affect, not likely to adversely affect" 4. Marbled murrelet — "No effect" This is the appropriate conclusion when effects on the species and their critical habitat are expected to be beneficial, discountable or insignificant. Limiting construction work to the approved work window will reduce direct impacts on the listed species. Shading impacts on the benthic environment will be minimized by the conservation measures discussed above.

Essential Fish Habitat Assessment A. Background The Magnuson -Stevens Fishery Conservation and Management Act (MSA), as amended by the Sustainable Fisheries Act of 1996 (Public law 104-267), requires Federal agencies to consult with NMFS on activities that may adversely affect designated Essential Fish Habitat (EFH) for the relevant species. According to the MSA, EFH means "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." For the Pacific West Coast, the Pacific Fisheries Management Council (Council) has designated EFH for federally managed groundfish (PFMC 1998a), coastal pelagic (PFMC 1998b) and Pacific salmon fisheries (PFMC 1999). The purpose of the EFH Assessment is to determine the effects of the proposed project on the EFH for the relevant species and to recommend conservation measures to avoid, minimize or otherwise offset adverse effects on EFH. B. Identification of EFH The designated EFH for groundfish and coastal pelagic species encompasses all waters from the mean high water line, and upriver extent of saltwater intrusion in river mouths, along the coasts of Washington, Oregon and California, seaward to the boundary of the U. S. exclusive economic zone (370.4 kin) (PFMC 1998a, 1998b). The designated EFH in estuarine and marine areas for Pacific salmon species extends from the nearshore and tidal submerged environments within state territorial water out to the full extent of the exclusive economic zone (370 .4 km) offshore of Washington, Oregon and California north of Point Conception to the Canadian border PFMC, 1999). Freshwater EFH for Pacific salmon includes all those streams, lakes, ponds, wetlands and other water bodies currently, or historically accessible to salmon in Washington, Oregon, Idaho and California, except areas upstream of certain impassable man-made barriers, and longstanding, naturally -impassable barriers. Chinook salmon and coho salmon are the species with designated EFH that are found in Lake Washington C. Proposed Action The details of the proposed project are presented in section of the attached BE/Lake and Stream Study Report. D. Effects of the Proposed Action The effects of this project on designated EFH are likely to be similar to the effects described in detail in the Effects Analysis section of the attached BE/Lake and Stream Study Report. The project is likely to have no permanent, long-term effects EFH designated for Chinook and coho salmon. E. EFH Conservation Measures The conservation measures mentioned in the attached BE/Lake and Stream Study Report will be implemented to minimize possible adverse effects to EFH. F. Conclusion The project may have temporary adverse effects on EFH the salmon species, but will not produce long-term adverse effects on EFH for the above species.

Assessment of Impacts to Critical Habitat for Puget Sound Chinook Project description: Construction of a new community -use dock on bake Washington in Renton, This assessment covers the primary constituent elements (54 CFR Part 226, page 74581-2) determined essential to the conservation of Puget Sound Chinook salmon (Oneorhynchus tshawytscha): (1) Freshwater spawning sites with water quantity and quality conditions and substrate supporting spawning, incubation, and larval development. Existing Conditions: There are no suitable freshwater spawning sites at the project location. (2) Freshwater rearing sites with water quantity and floodplain connectivity to form and maintain physical habitat conditions and support juvenile growth and mobility; water quality and forage supporting juvenile development; and natural cover such as shade, submerged and overhanging large wood, logjams and beaver dams, aquatic vegetation, large rocks and boulders, side channels, and undercut banks. Existing Conditions: Native vegetation has been planted immediately landward of the bulkhead in conjunction with the upland development. There is a concrete/rock bulkhead along the shoreline of both properties. No side channels or undercut banks were noted. (3) Freshwater migration corridors free of obstruction with water quantity and quality conditions and natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, side channels, and undercut banks supporting juvenile and adult mobility and survival. Existing Conditions: See (2) above. (4) Estuarine areas free of obstruction with water quality, water quantity and salinity conditions supporting juvenile and adult physiological transitions between fresh -and saltwater; natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, and side channels, and juvenile and adult forage, including aquatic invertebrates and fishes, supporting growth and maturation. Existing Conditions: See (2) above. (5) Nearshore marine areas free of obstruction with water quality and quantity conditions and forage, including aquatic invertebrates and fishes, supporting growth and maturation; and natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulder and side channels. Existing Conditions: The site is in a freshwater area. (6) Offshore marine areas with water quality conditions and forage, including aquatic invertebrates and fishes, supporting growth and maturation. Existing Conditions: The site is in a freshwater lake area. MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project- 28 7 r. ri � s " Effects Analysis: A complete discussion of the effects of this project is seen in the BE/Lake and Stream Study Report. Construction will produce brief and localized increased turbidity, which will be contained by a silt curtain. The project will have no long-term impacts on water quantity, salinity conditions or water temperature. Construction during work windows will prevent impacts to the listed fish species. Shading impacts on the benthic environment will be reduced by design components of the proposed project. The entire dock will be fully grated. Only two 4" diameter steel pilings will be used to support the first 41' of the pier to minimize migration obstacles for young salmonids that prefer the shallowest areas. The construction barge will not be allowed to ground out on the lake bottom at anytime. Additional native vegetation will be planted. Determination of Effect: "May affect, not likely to adversely affect" MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project- 29 Attachment 5. Assessment of Impacts to Critical Habitat for Coastal - Puget Sound Bull Trout Applicant: Richard DiCerchio The primary constituent elements determined essential to the conservation of bull trout (Salvelinus confluentus) are: (1) Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures from 32 to 72 °F (0 to 22 °C) but are found more frequently in temperatures ranging from 36 to 59 °F (2 to 15 °C). These temperature ranges may vary depending on bull trout life history stage and form, geography, elevation, diurnal and seasonal variation, shade, such as that provided by riparian habitat, and local groundwater influence. Stream reaches that preclude bull trout use are specifically excluded from designation. Existing Conditions: The project will take place in Lake Washington, a large body of fresh water. Effects to PCE: The project is not expected to have any influence on the water temperature of Lake Washington. (2) Complex stream channels with features such as woody debris, side channels, pools, and undercut banks to provide a variety of depths, velocities, and in stream structures. Existing Conditions: Project will take place in Lake Washington - not in a stream environment Effects to PCE: No effect (3) Substrates of sufficient amount, size and composition to ensure success of egg and embryo overwinter survival, fry emergence, and young -of -the year and juvenile survival. This should include a minimal amount of fine substrate less than 0.25 in (0.63 cm) in diameter. Existing Conditions: No spawning activity at the site Effects to PCE: No effect (4) A natural hydrograph, including peak, high, low. and base flows within historic ranges or, if regulated, currently operate under a biological opinion that addresses bull trout, or a hydrograph that demonstrates the ability to support bull trout populations by minimizing daily and day-to-day fluctuations and minimizing departures from the natural cycle of flow levels corresponding with seasonal variation: This rule finds that reservoirs currently operating under a biological opinion that addresses bull trout provides management for PCEs as currently operated. Existing Conditions: Project will take place in Lake Washington Effects to PCE: The project does not involve any alteration in the lake level; therefore it will have no impact on this PCE. MSS.A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project- 30 a (5) Springs, seeps, groundwater sources, and subsurface water to contribute to water quality and quantity as a Cold- water source. Existing Conditions: See 4 above Effects to PCE: This project will have no impact on springs, seeps, groundwater sources or subsurface water (6) Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows. Existing Conditions: Native vegetation has been planted along the site shoreline. Effects to PCE: The proposed dock will incorporate design components that will decrease negative impacts on foraging habitat and migratory corridors. The proposed dock will be fully grated. (7) An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish. Existing Conditions: Native vegetation has been planted along the site shoreline. Effects to PCE: See 6 above (8) Permanent water of sufficient quantity and quality such that normal reproduction, growth and survival are not inhibited. Existing Conditions: See 4 above. Effects to PCE: Pile driving may produce temporary turbidity impacts. These are expected to be short term and are not expected to have a significant impact on critical habitat. Any debris associated with the project construction phase will be contained by a silt containment curtain. Determination of Effect: "No destruction or adverse modification" Conservation Measures: Conservation measures for this project are seen in the BE/Lake and Stream Study Report. MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project• 31 EXHIBIT 9 Project Narrative DiCerchio Bulkhead The proposed project is to repair an existing rock bulkhead for the property located at 4005 Williams Avenue North in Renton Washington. A shoreline exemption and environmental review are required from the City of Renton. The project site and adjacent properties are zoned as Residential 10du/ac (R-10). The project site is on the shoreline of Lake Washington and is approximately 175' from May Creek. Richard DiCerchio is the owner of the property. The property is a single family residential lot with an existing single family house. The existing bulkhead is constructed of rock and is approximately 4 feet in height. The bulkhead is in poor condition and sections of the bulkhead have collapsed into the lake. There is erosion occurring to the soil landward of the bulkhead. The bulkhead will be repaired by rebuilding the bulkhead which is approximately 81 lineal feet in length. Approximately 50% +/- of the existing bulkhead rocks will be replaced. Forty cubic yards of 4" to 6" crushed rock and forty cubic yards of 1" minus crushed rock will be added landward of the bulkhead to improve drainage and prevent erosion of the soil landward of the bulkhead. Forty cubic yards of 1" minus spawning gravel will be placed waterward of the bulkhead as required by the Washington Department of Fish and Wildlife. Geotech filter fabric will be placed between the soil and the crushed rock to further prevent erosion. The existing soil type is norma sandy loam. A floating silt curtain will be placed around the work area to contain turbidity to the work area. The estimated fair market value of the project is $32,000. The work is exempt from the requirement of a shoreline substantial development permit because it is repair of an existing structure in like kind (WAC 173-27-040). The work will take place during the summer or fall of 2015. Authorization from the Army Corps of Engineers and the Washington Department of Fish and Wildlife is required for the project.

Lake Washington is designated as Shorelines of Statewide Significance and May Creek is a regulated shoreline. Both are regulated by the City of Renton Shoreline Master Program. The proposed bulkhead repair work location is within the May Creek and Lake Washington shoreline jurisdiction. The Lake Washington shoreline at the site is classified as a "High Intensity Overlay District" and the May Creek shoreline is identified as "Urban Conservancy." A previous land use application for a shared boat lift was reviewed and approved for the subject site and northerly single-family neighbor through City file number LUA14-001811. The subject site contains a single-family residence at 4005 Williams Aye Nilocated in the Barbee Mill subdivision�Zoned R-10 (Exhibit 3). The site slopes towards the bulk ead ' nd lake shoreline, with the steepest slopes approximately 40% (Exhibit 10). The project value is estimated at $32,000. The project work is proposed in the summer or fall 2015. The proposed project encompasses replacement of approximately 50% of the 6 -foot high piled rocks that run along 81 lineal feet of shoreline (Exhibit 4). The bulkhead would be repairedlas some areas have fallen into the lakand erosion from the uplands is occurring (Exhibit 5). Approximately 40 cubic yards of 4 to 6- inch crushel rock and 40 cubic yards of 1 -inch minus crushed rock are proposed landward of the bulkhead) to improve drainage and prevent future erosion of the soil (Exhibit 5). The bulkhead design identifies the large boulder rocks atop a 6 -inch crushed rock base and a depth of two feet of the wall below the bottom surface of the lake (Exhibit 4). Approximately 40 cubic yards of 1 -inch minus spawning gravel is proposed r waterward ate bulkhead (Exhibit 9). The size and type of rock that would be imported and used as replacement of smaller rock was not identified in the application materials. The submitted geotechnical evaluation states that the existing bulkhead has failed partly due to lack of batter/angle of the walllin addition to lack of construction technique and materials used previously (Exhibit 6). A geotech filter fabric is proposed between the uplands soil and crushed rocl� to be placed behind the wallito prevent long-term erosion. For construction, a floating silt curtainjis proposed to be placed around the work area to contain turbidity to the work area (Exhibit 6). The submitted Biological Evaluation/Lake and Stream Study/Habitat Data Report and Addendum (Exhibit 7), prepared by Marine Surveys & Assessments, dated August 25, 2014, has determined that no -net -loss of ecological function would result from the project's impacts with the previously approved shoreline plantings from the shared dock project (LUA14-001181). No comments were provided by reviewing agencies or from the general public. Beyond City of Renton approvals, the applicant would need to receive additional state and federal approvals, potentially including a Hydraulic Permit Approval (HPA) from state Department of Fish and Wildlife, federal Army Corps of Engineers approval, and potenti NNas some of the bulkhead is outside the inner harbor line. Documentation of state and federal permits would be provided prior to building permit issuance.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The subject bulkhead along the Lake Washington shoreline is failing, where large bulkhead rocks are falling into the lake and erosion of upland soils are seeping through the wall (Exhibit 5). The subject bulkhead runs along much of the shoreline, along the westerly and City of Renton Department of Community & Economic Development Environmental Review Committee Report DICERCHIO SINGLE-FAMILY BULKHEAD REPAIR LUAIS-000274, ECF, SM Report of June 1, 2015 Page 4 of 7 southerly areas of the subject site. The proposed project requires restacking of existing rocks and addition of crushed ;ock behind the wall for support (Exhibit 9). Approximately 50% of the existing larger wall rocks tree replaced with rocks brought from off-site. The type and size of rocks to be used as replacements are not identified in the submittal items. Therefore, staff will be recommending as a part of the SME)that the applicant be required to provide a source statement of the large rocks to be used in the bulkhead repairle statement shall be provided with type of rock and sizesaas part of a City of Renton building permit. %qV,*1cA The proposed building section of the bulkhead identifies crushed rock fill to be added at the back, or uplands, of the bulkhead and as a base (Exhibit 4). An approximate total of 80 cubic yards of crushed rock is proposed to be added uplands of the bulkhead. Approximately 40 cubic yards of 4 - to 6 -inch crushed rock and 40 cubic yards of 1 -inch minus crushed rock are proposed landward of the bulkhead to improve drainage and prevent future erosion of the soil (Exhibit 5). Waterward of the bulkhead, the applicant proposes approximately 40 cubic yards of 1 -inch minus spawning gravel. The area waterward of the bulkhead is outside of the Inner Harbor Line and within Washington Department of Natural Resources (DNR) owned property of Lake Washington (Exhibit 3). Work within DNR regulated areacrequire(coordination with the state agency. Therefore, staff will be recommending as a part of the SME that the applicant be required to contact DNR to receive permission to add spawning gravel lo, the lakebed�where proposed. Approval from DNR shall be provided to the City of Renton prior to building permit issuance. The submitted Geotechnical Engineering Report, by RMI Associates, dated April 14, 2015, provides review of the existing and failing bulkhead wall and provides recommendations for repair of the wall (Exhibit 6). The geotechnical engineer states that the rock bulkhead fails in several areas where the bulkhead had lost fill and small rock along the bulkhead end also notes that the face of the bulkhead lacks sufficient batter (angle)Vnd there is no apparent drainage rock behind the bulkhead. The geotechnical evaluation states that in general4the bulkhead is not performing well along most of its lengthiand that the failures appear to be due to the construction technique and materials used in original construction. The engineer recommends that the bulkhead be reconstructed to improve the batter and replace any unsuitable rock, and that repair should include drainage material and fabric behind the bulkhead to minimize the potential for piping and erosion behind the rock face. Mitigation Measures: None Nexus: N/A 2. Water a. Wetland, Streams, Lakes Impacts: The project is proposed to occur in Lake Washington, beginning inside of the designated Inner Harbor and extending waterward outside of the Inner Harbor line (Exhibit 3) and ending in May Creek shoreline. There are two shoreline designations at the site, split between the Lake Washington "High Intensity Overlay District" and May Creek "Urban Conservancy Overlay District" (RMC 4-3-090G) (Exhibit 2). Lake Washington is a Shoreline of Statewide Significance and is included as a Shoreline of the State. As a Class 1 lake, it is a perennial salmonid -bearing body of water. May Creek is a City regulated shoreline. The applicant submitted a joint Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8), dated August 25, 2014, prepared by Marine Surveys & Assessment )for the previously ERC RepQrt LVA15-000274 DiCerchio Bulkhead Repair City of Renton Department of Community & Economic Development Environmental Review Committee Report DICERCHIO SINGLE-FAMILY BULKHEAD REPAIR LUA15-000274, ECF; SM Report of June 1, 2015 Page 5 of 7 applied for and approved shared dock (LUA14-001181). An Addendum to the evaluation was subsequently provided for the subject bulkhead work, by the same authors, dated April 10, 2015 (Exhibit 7). These documents conform to the requirements for Biological Evaluation/Lake and Stream Study/Habitat Data Report per RMC 4-8-120D. The original biological evaluation and addendum for the subject bulkhead project finds a no -net -loss of ecological function will result from this project. The addendum dated April 10, 2015 states that the new spawning gravel mix waterward of the bulkhead will improve the baseline habitat conditions. As part of the construction mitigation, the project narrative states that a floating silt curtain will be placed around the work area to contain turbidity during the repairs. Therefore, staff recommends that a floating silt curtain be a requirement of the construction phase and that the curtain remain in place until repair and maintenance activities are completed. Mitigation Measures: None Nexus: N/A 3. Vegetation Impacts: The submitted original Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) provides background of the redevelopment of the Barbee Mill community where upland restoration of the overall Barbee Mill site involved removal of fill soils behind the bulkhead, along with asphalt, a pier, wooden bulkhead and pilings associated with the previous industrial mill operation. Extensive shoreline restoration was completedialthough the subject properties are located south of the extensive remediation that occurred. As part of site redevelopment, a planted buffer along the shorelin of approximately 35 feettvas required along the Lake Washington shoreline of the Barbee Mill subdivision. The applicant does not propose any new plantings beyond those that have been required for the 35 -foot planted buffer and plantings as mitigation for the new shared moorage pier (as required through the approval for LUA14-001181). The applicant identifies that any removed soils or vegetation that occurs as part of the bulkhead work would be replaced (Exhibit 9). Staff recommends that the applicant be required to replace any upland vegetation removed or damaged1as part of the bulkhead repair. The replaced plantings shall be equal to or better than existing conditions. The applicant did not provide a construction mitigation plan, as such staff is not able to identify if there would be impacts to existing vegetation due to delivef rocks for the bulkhead. Therefore, staff recommends that the applicant be required to provid a construction mitigation plan with the hours of work, path to bulkhead, and locations on the subject site or other areas nearby that may be impacted. Mitigation for these impacts should be provided with the plan. Mitigation Measures: 1. The applicant shall improve any surface soils or vegetation uplands of the bulkhead that are removed or damaged as part of the bulkhead repair to existing or better conditions. A replacement plant plan shall be provided to the Current Planning Project Manager for review and approval prior to building permit issuance. 17 2. The applicant shall provide a construction mitigation plan s.h.a.l.lhe4mohided with the hours of work and locations on the subject site that may be impacted.

Wildlife Impacts: The Biological Evaluation/Lake and Stream Study/Habitat Data Report and Addendum submitted for the proposed project includes analysis of birds, mammals, and fish in the evaluation. The study states that the only wild mammals reported as observed in the general area are deer. The following bird species observed on or near the project site: hawks, herons, eagles, quail, osprey, cormorants and songbirds. The original Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) study states that bald eagles are no longer on the list of threatened or endangered species under the Endangered Species Act but continue to be prate ed by the Bald and Golden Eagles Protection Act and the Migratory Bird Treaty Act are protected "sensitive species" in Washington State. Sensitive species are vulnerable or declining and likely to become endangered or threatened in a significant portion of their range within the slatel without cooperative mana ement or removal of threats. In addition, the a Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) indicates that salmonids observed at the site include salmon and trout. Salmonids known to be present in southern Lake Washington include Puget Sound Chinook salmon, Coho salmon, sockeye salmon, steelhead trout, bull trout and cutthroat trout. Puget Sound Chinook, Puget Sound steelhead and bull trout are all listed as threatened under the Endangered Species Act (ESA). Previous shoreline remediation accomplished in conjunction with the development of the plat was designed to be consistent with Water Resource Inventory Area (WRIA) 8 Conservation Plan recommendations. As a result of remediation, shoreline that was previously unsuitable habitat for fish and other aquatic life due to extensive shoreline modifications and industrial use of the sitepas been restored. The Biological Evaluation/Lake and Stream Study/Habitat Data Report (Exhibit 8) and Addendum to the Report (Exhibit 7) provide evaluation of the specific species and habitat protected by federal jurisdiction, including Puget Sound Chinook, Bull Trout, Puget Sound Steelhead, and Marbeled Murrelets. The Murrelets are unlikely to be present in the project vicinity according to the study, due to there not being a nesting area nearby and that the area is highly urbanized and within close proximity of a major highway corridor. The proposed bulkhead construction sequencing and mitigation proposed by the applicant would include the installation of a silt curtain. The silt curtain should minimize impacts to fish species as a result of activities associated with the proposed project. If at any time, as a result of project activities, fish are observed in distress, a fish kill occurs, or water quality problems develop (including equipment leaks or spills), operations shall immediately cease and the Washington Department of Fish and Wildlife (WDFW) and the Washington Department of Ecology shall be contacted immediately. Work shall not resume until further approval is given by the WDFW. The Washington Department of Fish and Wildlife has established a construction window for this portion of Lake Washington. The construction window allows for overwater construction to occur only between July 16 and December 31. Therefore, staff will b,recommending as a part of the SMF that the applicant be required to adhere to this established in water construction window. Construction shall take place only during the Department of Fish and Wildlife approved in -water". construction window from July 16 through December 31, unless approved otherwise by Department of Fish and Wildlife.

The items are as follows. 1) A biological assessment has been included. Note that this assessment is an addendum to the one done for the pier at the site. I have included both the original assessment and the addendum. 2) Included is my correspondence with the Washington Department of Ecology regarding the MTCA cleanup area at Barbee Mill. I have also included a map of the cleanup area provided by ecology and an aerial overlay showing the location of the cleanup area relative to the proposed project. Jeremy Porter, a consultant for ecology, stated in our correspondence that the proposed project will not impact the cleanup area or the remediation components. 3) Included is an assessment of why the existing wall failed done by RMI Associates, a geotechnical firm. The report address what led to the failure of the existing wall and provides recommendations on how the wall should be rebuilt to prevent future failures. I hope that all of the above items have been addressed satisfactorily. Please feel free to contact me if you have any questions, or if you require any additional information.

Over the phone, Evan and I talked through the missing items: 1) biological assessment, basically an update to the one for the dock that needs to discuss any impacts and the mitigation for those impacts, where no -net loss per the SMP is determined, 2) MOTCA clean-up related information for the Superfund site at Barbee Mill (Evan has a contact at DOE or start with Conner Homes which should have information), and 3) geotech or engineering of wall — the wall is small but if it is not working now after recently being constructed, what is going to cause this not to do the same in the future once you've completed the proposed work? At least start on 1 and 2 to complete the packet and I am working on getting an answer for 3. There is no need for the Pre -App on the 16th that Richard signed up for. I am cancelling that meeting.

Renton, WA 98056 Case # , Biological Evaluation Dated August 25"', 2014 To: Whom it may concern, Please accept this addendum letter for the addition of the repair of an existini bulkhead to the original Biological Evaluation for the DiCerchio Pier, Ramp, and Float project dated August 25` , 2014. This letter describes the nature of the additional project component, addresses any potential impacts of this addition as well as provides an impact determination and net -loss analysis. A. Project Description The proponents are proposing to repair an existing bulkhead at the Dicerchio site (see Figures 1-3). The repair will consist of restacking rocks and installing crushed rock drainage material landward of the existing bulkhead. It is estimated that approximately 50% plus or minus of the existing bulkhead rocks will be replaced with new rocks. Forty cubic yards of 4" to 6" crushed rock and 40 cubic yards of minus crushed rock will be added landward of the bulkhead for drainage material. In addition, 40 cubic yards of spawning gravel mix will be added waterward of the repaired bulkhead as mitigation. B. Impacts of the Project The proposed project is a bulkhead repair project, not a new bulkhead project. Therefore, there will be no change in the baseline habitat conditions. In fact, the addition of the spawning gravel mix will actually improve the baseline habitat conditions. C. Net -Loss Determination All measures have been taken to avoid and minimize potential impacts resulting from the proposed project (see BE). In consideration of the unlikely impact to ESA species as well as the proposed mitigation planting proposed in the BE, which will enhance the habitat, we determine that no -net -loss of ecological function will result from the repair of the existing bulkhead. Additionally we believe that this project reflects the goal of the Shoreline Master Program by balancing access to the environment with the protection of that environment. As mentioned above, a planting plan was submitted as mitigation in the BE and that will be included as mitigation for the bulkhead work also. There is an existing vegetation buffer along the shoreline at the site any vegetation disturbed by excavation for this project will be replaced on a one to one basis.

Effects determination As stated in the original Biological Evaluation (BE) document the determination of effects for ESA species in the area are provided below: 1. Puget Sound Chinook — "May affect, not likely to adversely affect" 2. Bull Trout — "May affect, not likely to adversely affect" 3. Puget Sound Steelhead — "May affect, not likely to adversely affect" 4. Marbled Murrelet — "No effect" Thank you for the opportunity to addend and comment on this project.

Existing Shoreline Stabilization Structures Code sections are listed in bold and information regarding how the projects meets each code section is listed below each code section in plain text. Existing shoreline stabilization structures not in compliance with this Code may be retained, repaired, or replaced if they meet the applicable criteria below: i. Repair of Existing Structures: An existing shoreline stabilization structure may be repaired as long as it serves to perform a shoreline stabilization function for a legally established land use, but shall be subject to the provisions below if the land use for which the shoreline stabilization structure was constructed is abandoned per RMC 4-10- 060, Nonconforming Uses, or changed to a new use. The existing bulkhead provides shoreline stabilization for the existing single family residence on the site that was legally established under permit number 1313005514. ii. Additions to Existing Structures: Additions to or increases in size of existing shoreline stabilization measures shall be considered new structures. The proposed bulkhead repairs will not create additional bulkhead or increase the size of the bulkhead. iii. Changes in Land Use: An existing shoreline stabilization structure established to serve a use that has been abandoned per RMC 4-10-060, Nonconforming Uses, discontinued, or changed to a new use may be retained or replaced with a similar structure if: (a) There is a demonstrated need documented by a geotechnical analysis to protect principal uses or structures from erosion caused by currents or waves; and This section is not applicable because there is no change in land use proposed for the project_ (b) An evaluation of the existing shoreline stabilization structure in relation to the hierarchy of shoreline stabilization alternatives established in subsection F4alii of this Section shows that a more preferred level of shoreline stabilization is infeasible. In the case of an existing shoreline stabilization structure composed of rigid materials, if alternatives (a) through (c) of the hierarchy in subsection F4alii of this Section would be infeasible then the existing shoreline stabilization structures could be retained or replaced with a similar structure. RECEIVED APR 2 3 2015 CITY OF RENTON PLANNING UIVISJON IL This section is not applicable because there is no change in land use proposed for the project. iv. Waterward Replacement Prohibited for Structures Protecting Residences: Replacement walls or bulkheads, if allowed, shall not encroach waterward of the ordinary high-water mark or existing structure unless the residence was occupied prior to January 1, 1992, and there are overriding safety or environmental concerns. In such cases, the replacement structure shall abut the existing shoreline stabilization structure. The bulkhead repairs will not result in the encroachment waterwater of the ordinary high- water mark of the bulkhead. The repaired bulkhead will be at or landward of the existing ordinary high-water mark. v. Restoration and Maintenance of Soft Shorelines Allowed. Soft shoreline stabilization measures that provide restoration of shoreline ecological functions may be permitted waterward of the ordinary high-water mark. Replenishment of substrate materials to maintain the specifications of the permitted design may be allowed as maintenance. This section is not applicable because it does not involve the restoration or maintenance of soft shorelines. vi. No Net Loss: Where a net loss of ecological functions associated with critical habitats would occur by leaving an existing structure that is being replaced, the structure shall be removed as part of the replacement measure. The proposed project will result in the repair and clean up of the existing failed bulkhead sections that have fallen into the lake. This will benefit ecological functions at the site by removing rock debris from the lake that could provide ambush habitat for predators of juvenile salmon. RMI ASSOCIATES LLQ.

INTRODUCTION The purpose of this study and report is to present our findings, opinions, and conclusions regarding existing geotechnical conditions within the site. Specifically, we have evaluated the bulkhead which has had several failures and are providing a geotechnical engineering report discussing those conditions. The scope of our services includes surficial observations and assessment of the sloping areas. Using the data, we have listed our opinions and recommendations. Our scope of services includes the following: 1 2 3 Review geologic maps of the area and information in our files. Perform a walk-through evaluation of existing geotechnical and relative stability conditions at the site.

Decerchio Bulkhead Failure April 14, 2015 RMI File No. 69415 Page 2 SITE CONDITIONS Surface The site consists of an approximately 4 -foot tall rock bulkhead along the west and south sides of a residence located at 4005 Williams Avenue North. The site is bounded on the west by Lake Washington and on the south by the mouth of May Creek. Williams Avenue is east of the residence and another residence is situated north of the site. The rock bulkhead is founded on beach deposits, recent alluvium or artificial fill. The soil surface declines underwater gently to the west of the bulkhead. We also noted a failure about the middle of the west bulkhead and several areas where the bulkhead had lost fill and small rock along the bulkhead. We also noted that the face of the bulkhead lacks sufficient batter and there was no apparent drainage rock behind the bulkhead. Geolo Most of the Puget Sound region was affected by past continental glaciations. The last period of glaciation, the Vashon Stade, ended approximately 10,000 to 11,000 years ago. Many of the geomorphic features seen today are a result of scouring and overriding by glacial ice. During the Vashon Stade, the Puget Sound region was overridden by over 3,000 feet of ice. Soil layers overridden by the ice sheet were compacted to a much greater extent than those that were not. A typical glacial sequence includes glacial till overlying advance outwash, underlain by transitional deposits and older non -glacial and glacial sediments. We reviewed the Geologic Mat) of King County. Washington, by Booth, D. B., Haugerud, R. A., and Sacket, J. (in press online, for the site geology. The site area has younger alluvium mapped along the west side of the mouth of May Creek with possible artificial fill mapped under the site. We also understand the site may have been constructed on fill placed over contaminated soil. RMI ASSOCIATES LLC S i Geotechnical Engineering Report Decerchio Bulkhead Failure April 14, 2015 RMI File No. 69415 Page 3 Explorations No subsurface explorations were performed. We observed sands with gravel and pieces of rock derived from the failed rock bulkhead in exposures below the bulkhead face. This is consistent with recent beach deposits derived from younger alluvium or artificial fill. Observations We noted that in general the bulkhead is not performing well along most of its length. The failures appear to be due to the construction technique and materials used in construction of the bulkhead. Particularly we noted the quality of the rock used and the lack of batter in the construction. Recommendations We recommend that the bulkhead be reconstructed to improve the batter and replace any unsuitable rock. The rebuild should include drainage material and fabric behind the bulkhead to minimize the potential for piping and erosion behind the rock face. The planned construction should solve the issues that led to the failures.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonabl related to determining if there may be significant adverse impact.

PROJECT DESCRIPTION A. Project Location: '/4 Section NW32, Township 24N, Range 05E. 4005 and 4011 Williams Avenue N Renton, WA 98055 Latitude: 47.52848° N Longitude: 122.20532°W See Figure 1 for project location. B. Site Description: The proposed project is a joint -use pier to be located along the common property line between two abutting lots, 4005 and 4011 Williams Ave N, Renton, WA 98056 (jointly the "subject property"), presently owned by Richard DiCerchio and Barbee Mill Waterfront LLC, respectively, (jointly the "applicant" for the requested shoreline substantial development permit). The properties are located within the Barbee Mill Community, a major waterfront subdivision. The subject property is located along the eastern shore of Lake Washington in the City of Renton (Figure 2). The proposed joint -use pier would provide moorage and facilitate access to Lake Washington for residents of the subject property and their guests. Two bodies of water are adjacent to, or flow through, the Barbee Mill Community: Lake Washington and May Creek. The subject property is located along Lake Washington, a Shoreline of Statewide Significance as provided in RMC 4-3-090F1, and a Shoreline of the State under RMC 4-11-190. This Lake Study is prepared in accordance with the requirements of RMC 4-8-120D with respect to the Lake Washington shoreline of the subject property. May Creek, a Shoreline of the State (RMC 4-3-090F2), flows through the Barbee Mill Community. The May Creek open space (a riparian buffer) and a street are located between the two lots and May Creek. The Barbee Mill Community is located on the approximately 22 acre site of the former Barbee Mill Company lumber mill. The Barbee Mill Community has 114 multi -story paired homes, a pond, walking trails and lakefront open space for the use of residents. Lots 23 through 48 are lakefront lots. To restore the former industrial site to a parcel suitable for a residential waterfront subdivision, the mill buildings were demolished; fill soils were removed from behind the bulkhead; asphalt paving, a pier, the wooden bulkhead and piling associated with the mill operation were removed; and extensive shoreline restoration was completed. The subject property is located south of, and was not included in, this extensive remediation. A concrete bulkhead is located along most of the Barbee Mill Waterfront LLC parcel; a rock bulkhead is located along the DiCerchio parcel. The substrate immediately waterward of the property consists of large and small cobble. A number of factors were considered in determining the location of the proposed pier, most importantly the lower environmental impact of a joint -use structure over individual single -property use piers. In establishing design parameters for the proposed joint -use pier, it was required that it not interfere with the general public's use and enjoyment of Lake Washington, that it not pose a navigation hazard to boaters, and that it not interfere with the use of existing or future neighboring docks or piers. C. Lake and Stream Classifications: As mentioned above, as a Shoreline of Statewide Significance (RMC 4-3-090F1), Lake Washington is included in the definition of a Shoreline of the State (RMC 4-11-190). Lake Washington is a Class I lake as it is a perennial salmonid -bearing body of water classified as a Shoreline of the State (RMC 4-11-19051). May Creek is an MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project- 3 important salmonid stream that is classified by the City of Renton and the State of Washington as Class 1 waters and included within the definition of a Shoreline of the State (RMC 4-3-090F2). D. Shoreline Restoration: Prior to restoration of the beach in conjunction with vacation of the land, the Lake Washington shoreline north of the subject property was heavily bulkheaded, back-filled and covered with impervious asphalt paving; numerous piling and substantial quantities of concrete rubble and other shoreline debris were on the site. Pursuant to the general development site remediation, upland and in -water structures including the timber bulkhead and piling were removed, shoreline rubble was removed, fill soil was excavated to subgrade elevations, toe rock and a temporary quarry spall erosion control berm were installed, and sand, gravel and rock materials were used to construct a beach to mimic natural conditions. Although the area of extensive remediation did not encompass the subject property, a planting buffer of native vegetation (Figure 6 and 7) was installed along all the lakefront lots, including the subject property, to environmentally and functionally enhance the entire development shoreline. The Ordinary High Water (OHW) mark for Lake Washington is the line of mean high water (RMC 4-11-150 Definitions 0). The Lake Washington water depth is controlled by the Army Corps of Engineers at the Hiram M. Chittenden Locks and is at 21.8' of lake elevation. In the course of the Barbee Mill Beach Restoration site remediation, permanent toe rock was installed along the OHW line. As of March 20, 2007, the date a SCUBA survey was conducted for purposes of identifying flora, fauna, substrate types and other qualitative information relative to the Biological Evaluation prepared for the previous community dock project, coir rolls were located along the OHW line within the remediation area_ The May Creek OHW mark is the mean high water line of the stream (RMC 4-11-150 Definition O). E. Vegetative Cover of the Site: The study area includes no wetland or flood hazard areas; it does include Lake Washington riparian areas. Prior to the Barbee Mill Beach Restoration project, riparian vegetation was found to be generally absent within the study area as the shoreline behind the bulkhead was paved_ In unpaved areas, vegetation noted included Juncus effusus (soft rush) and Iris pseudocaris (a non-native iris). The upland redevelopment required extensive regrading and clearing; a mitigation planting plan was agreed upon that includes planting along the Lake Washington shoreline. In accordance with this mitigation plan, plantings on the subject property have been installed (Figures 6 and 7). In conjunction with construction of the proposed joint -use pier, 22 additional native shrubs will be planted. The planting plan details will be shown on the full size drawings. F. Ecological Functions of Lake Washington along the Study Area: Previously to the Barbee Mill Community development, the industrial structures and use of the site limited the ecological functions that would otherwise have been provided by Lake Washington and its adjacent riparian area. As a result of the extensive general site restoration work completed north of the subject property, the ecological functions of the portion of the lake within the study area should be greatly enhanced. Previously planted riparian vegetation and additional plantings in conjunction with the proposed joint -use pie project will further assist in restoring the ecological functions of Lake Washington. Much of this new vegetation will be overhanging, providing shade and predator protection for fish and aquatic invertebrates. The newly planted riparian vegetation will add significant organic matter to the lake substrate in the form of leaves and woody debris that fall and wash into the lake. This will provide additional source of food, shelter and shade for aquatic invertebrates and fish. This increased vegetation will also provide food and shelter for terrestrial insects, and in turn provide an additional food source for birds and animals that feed upon them. The addition of riparian vegetation to this formerly near -barren site should also help water quality by filtering pollutants, removing nutrients and reducing sediments in any runoff from the adjacent upland development. The increased overhanging vegetation should facilitate the migration of juvenile salmon. MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project* 4 G. Fish and Wildlife Use or the Area: Birds: Birds observed on or near the site include hawks, hcrons, eagles, quail, osprey, cormorants and songbirds. Before the mill structures were demolished, an osprey nest was successfully relocated from the top of the old mill sawdust collector to a platform built on a 25' pole over the water not far from the original nest site. The osprey have accepted the new nest and a video camera records their activities for viewing over the Internet. Protected wildlife in Washington State shall not be hunted or fished (WAC 232-12-011). Protected wildlife noted from time to time within the general Barbee Mill Community development area includes the marbled murrelet and the bald eagle. The marbled murrelet is classified as a "threatened species," a species likely to become endangered within the foreseeable future throughout a significant portion of their range within the state without cooperative management or removal of threats. The bald eagle is no longer on the list of threatened or endangered species under the Endangered Species Act (ESA) but continues to be protected by the Bald and Golden Eagles Protection Act and the Migratory Bird Treaty Act and is protected as a "sensitive species" in Washington. Sensitive species are vulnerable or declining and likely to become endangered or threatened in a significant portion of their range within the state without cooperative management or removal of threats. Mammals: The only wild mammals reported as observed in the area are deer. Fish: Salmonids observed at the site include salmon and trout. Salmonids known to be present in southern fake Washington include Puget Sound chinook salmon, coho salmon, sockeye salmon, steelhead trout, bull trout and cutthroat trout. Puget Sound chinook, Puget Sound steelhead and bull trout are all listed as threatened under the ESA. Other fish observed at the site include bass. black crappie, bluegill, pumpkinseed sunfish, tench and yellow perch. The shoreline remediation was designed to be consistent with Water Resource Inventory Area (WRIA) 8 Conservation Plan recommendations. As a result of the remediation, shoreline that was previously unsuitable habitat for fish and other aquatic life due to extensive shoreline modifications and industrial use of the site has been restored. The restored gravel substrate and gently sloping bottom should provide favorable habitat for winter rearing of salmon fry. The new gravel and cobble substrate to the north and the existing cobble on the subject property should be suitable habitat for benthic invertebrates which would likely attract juvenile salmonids. H. Project Details: .The pier will be supported by two 10" diameter, four 8" diameter and two 4" diameter galvanized steel piles. It will have a 4' by 40' walkway from shore and a 6' by 40' walkway for a total length of 80' from the OHWM. Two free standing boat lifts will be installed at the pier. A 30' by 10.5' translucent canopy will be installed over one boat lift. Two 12" diameter steel mooring piles will be installed adjacent to the pier (Figures 3-5). I. Construction Sequence: 1. Mobilize construction barge to the site with all construction materials and equipment on board. Moor the barge as to prevent grounding on the lake bottom at any time during construction. 2. Install silt containment curtain around work area to contain any debris that may fall into lake waters. In the event any materials enter lake waters they will be retrieved immediately and placed in debris containers on the barge. 3. Using the barge -based crane and vibratory insertion/extraction system, install (2) at 12" diameter, (2) at 10" diameter, (4) at 8" diameter and (2) at 4" diameter galvanized steel piles to practical refusal. 4. Cut steel piling as necessary at the appropriate elevation. 5. Install pre -fabricated cap brackets to piling. Connect wood framing to cap brackets using hand tools. Install grated decking on pier. 6. Set boat lifts in place using crane on the barge. The translucent boat canopy will be installed by hand. MS&A DiCerch io/ Barbee Mill Waterfront LLC Joint -Use Pier Project- 5 7. Demobilize and dispose of all debris at approved upland disposal site. General Notes: 1. All treatments will be applied and fully cured prior to delivery to the site. J. Action Area: The action area should include the area within a one -mile radius of the project location. This area includes potential turbidity and noise impacts from the construction process. II. SPECIES AND HABITAT INFORMATION A. Species Information: In the project area, the Puget Sound chinook (Oncorhynchus tshawytscha) is listed under the Endangered Species Act as a threatened species according to the National Marine Fisheries Service (NMFS) (Federal Register, Vol. 64, No. 56). On May 11, 2007, NMFS also listed the Puget Sound steelhead (Oncorhynchus mykiss) as a threatened species under the ESA (Federal Register/ Vol. 72, No. 91 / Friday, May 11, 2007 / Rules and Regulations). Bull trout (Salvelinus confluentus) were listed as threatened by the United States Fish and Wildlife Service (USFWS) in October of 1999. On September 2, 2005, NMFS issued the final rule designating critical habitat for 12 Evolutionarily Significant Units (ESUS) of West Coast salmon, including the Puget Sound Chinook Salmon ESU and the Hood Canal Summer -run Chum ESU. The project site is in an area designated as critical habitat for the Puget Sound Chinook ESU (Federal Register / Vol 70, No. 170 / Friday, September 2, 2005 Rules and Regulations). USFWS has designated critical habitat in Lake Washington for Coastal -Puget Sound bull trout (Federal Register / Vol. 70, No. 185 / September 26, 2005 / Rules and Regulations). Puget Sound Chinook: Puget Sound chinook, also called the king salmon, are distinguished from all other Pacific salmon by their large size. Most chinook in the Puget Sound are "ocean -type" and migrate to the marine environment during their first year (Myers et al. 1998). They may enter estuaries immediately after emergence as fry from March to May at a length of 40 mm., or they may enter the estuaries as fingerling smolts during May and June of their first year at a length of 60-80 mm. (Healey 1982). Chinook fry in Washington estuaries feed on emergent insects and epibenthic crustaceans (gammarid amphipods, mycids, and cumaceans). As they grow and move into neritic habitats, they feed on decapod larvae, larval and juvenile fish, drift insects, and euphausiids (Simenstad et al. 1982). These ocean -type chinook use estuaries as rearing areas and are the most dependent of all salmon species on estuaries for survival. In the Lake Washington system, adult chinook salmon usually arrive at the Chittenden Locks in July, although there are some arrivals before and after July (Synthesis of Salmon Research and Monitoring. 2008). According to Fresh et al. (2000), the total time for salmon migration from the Locks to arrival at their tributary spawning grounds "can take up to 55 days, but averages less than 30." During much of this time, salmon hold in the upstream area from the Locks before moving through the Ship Canal and Lake Union. Fresh et al. (2000) found the average holding time to be from 17 to 19 days. After reach their spawning streams between September and November, spawning occurs from October to December. According to Tabor et al. (2006), "Fry emerge from their redds from January to March. Juvenile Chinook salmon appear to have two rearing strategies: rear in the river and then emigrate in May or June as pre-smolts, or emigrate as fry in January, February. or March and rear in the south end of Lake Washington or Lake Sammamish for three to five months." In the project area vicinity, juvenile chinook salmon from the Cedar River enter Lake Washington and rear in the south end of the lake primarily from January to May.

(2046) also reported that: Similar to results of 2002, juvenile Chinook salmon were concentrated in the south end of Lake Washington from February to May..... Therefore, it appears that the lake shore area near the natal stream is an important nursery area for juvenile Chinook salmon. In Lake Washington, the major part of this nursery area appears to be roughly from Pritchard Beach on the west shoreline and the mouth of May Creek on the east shore and the south part of Mercer Island. The distance from the mouth of the Cedar River to the edge of the nursery area is around 6 km. north of this area; the number of Chinook salmon would be expected to be relatively low until mid-May or June. In the same study cited above, it was found that marked Chinook did not move far from their release site at Gene Coulon Park (approximately 1.5 miles south of the current project site). Marked juveniles were observed 1, 7, 15, and 21 days after release at Gene Coulon Park. All of the marked salmon that the investigators observed had moved less than 150 m from their release site at the park. After moving slowly away from the Green River and south Lake Washington, juveniles reach the Chittenden Locks during the period between May and August, with peak migration through the Locks taking place in June. According to Kerwin (2001) chinook, coho, sockeye and winter steelhead use May Creek for spawning, rearing and migration. However, volunteers from the Volunteer Salmon Watchers Program have been observing salmon in May Creek since 2000. They have reported that only sockeye are seen consistently, while chinook, coho, cutthroat trout and kokanee salmon are less commonly seen. Hammer (2011) reported that the number of chinook varies from 0 to 12 fish annually in May Creek. WDFW reported three live chinook and one redd in 2010 spawner surveys. Bull Trout: Coastal -Puget Sound bull trout have ranged geographically from northern California (at present they are extinct in California) to the Bering Sea coast of Alaska, and northwest along the Pacific Rim to northern Japan and Korea. Bull trout are members of the char subgroup of the salmon family. Spawning occurs typically from August to November in streams and migration to the open sea (for anadromous populations) takes place in the spring. Eggs and juveniles require extremely cold water for survival. Temperatures in excess of about 15 degrees C are thought to limit bull trout distribution (Rieman and McIntyre 1993). They live both in fresh and marine waters. Some migrate to larger rivers (fluvial), lakes (adfluvial), or saltwater (anadromous) before returning to smaller streams to spawn. Others (resident bull trout) complete all of their life in the streams where they were reared. Habitat degradation, dams and diversions, and predation by non-native fish threaten the Coastal -Puget Sound population. The Coastal -Puget Sound bull trout population is thought to contain the only anadromous forms of bull trout in the contiguous United States (Federal Register, Vol. 64, No. 210, 1999). Two subpopulations of bull trout (also known as "native char") are considered within the Lake Washington area: the Chester Morse Reservoir population and the Issaquah Creek-Sammamish River population (Federal Register, Vol. 64, No. 210, 1999). "Only two `native char' have been observed during the past 10 years in the Issaquah Creek drainage and none have been observed in the Sammamish River system. It is questionable whether a viable subpopulation remains." (Federal Register, Vol. 64, No. 210, 1999). Puget Sound Steelhead: Wild winter steelhead enter the Lake Washington system in mid-December with peak spawning taking place in May. There have been high rates of predation by California sea lions at the Ballard Locks, which is one of the leading factors in the declining steelhead production in the Lake Washington system (1992 Washington State Salmon and Steelhead Stock Inventory. Appendix One - Puget Sound Stocks. Washington Department of Fish and Wildlife, Olympia, WA.). According to Kerwin (2001): The Lake Washington system supports one native winter steelhead stock but not a summer steelhead stock (SASSI 1994). The winter steelhead stock was listed in SASS1 as `'Depressed" but has recently shown some evidence of rebounding. A limited hatchery program utilizing the native winter steelhead stock was initiated in 1997 as a supplementation type program to assist in recovery of winter steelhead populations in the north Lake Washington tributaries. The sharp decline in Lake Washington winter steelhead was noted MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project- 7 as a reason for concern by NMFS in their stock status review (Busby 1996). However, in a more recent analysis, between 1986 and 2004 escapement for the Lake Washington winter -run steelhead ranged from 1,816 (1986) to 44 (2004) (WDFW 2004). Based on the chronically low escapement and short-term severe decline in escapements.. the stock status has decreased from its 1992 "depressed" status to "critical" in 2002. WDFW has reported steelhead in the lower 3 miles of May Creek (Salmon Scape, 2010). Marbled Murrelets: Marbled murrelets are small marine birds in the alcidae family. They spend most of their time at sea and only use old growth areas for nesting. In the critical nesting areas, fragmentation and loss of old growth forest has a significant impact on the survival and conservation of the species (WDW, 1993). Adult birds are found within or adjacent to the marine environment where they dive for sand lance, sea perch, Pacific herring, surf smelt and other small schooling fish, and feed on invertebrates. The project site is located in an urban environment adjacent to a major highway. There is a high level of ambient noise in the project vicinity. There is no nesting habitat near the site. Therefore, it is unlikely that murrelets will be present in the project vicinity. III. EFFECTS OF THE ACTION The status of each of the listed species in the action area has been provided. The proposed project has been described and the action area defined. When reviewing all the data, the potential direct and indirect effects of the proposed action on the listed species and their critical habitat should be considered. A. Direct Effects: When considering the direct effects of the proposed project, one must determine if the proposed project will immediately reduce or destroy the listed species and/or their habitat. The potential, direct impacts caused by the construction process include increased noise and turbidity. Pile driving noise: A vibratory pile driver will be used to drive the piles to practical refusal. Feist et al. (1992) reported that salmonids could be expected to hear pile driving noise approximately 2,000' from the source. Based on the studies at the Everett Homeport. these researchers concluded that pile driving did alter the distribution and behavior of juvenile pink and chum salmon. However, the Everett Homeport results may not be entirely applicable to the proposed project, because a diesel powered compression hammer was used in that study. As stated in the Feist report, "It would be reasonable to say that juvenile salmonids might respond differently to the sounds of a vibratory hammer. compared to that of a diesel compression hammer." As noted above, it is unlikely that murrelets will be present in the action area. Therefore, the construction process should have little or no impact on marbled murrelets. Turbidity: Increased turbidity caused by pile driving could, under certain circumstances, have adverse effects on salmon and bull trout. The effects depend on duration of exposure, concentration of turbidity and the life stage of the salmon during the increased exposure. The effects can be discussed in terms of lethal, sublethal or behavioral (Nightingale and Simenstad 2001 a and Simenstad, editor, 1988). A silt containment curtain will be installed in the project area to contain and minimize turbidity impacts. To minimize the adverse effects of increased turbidity and noise on migrating salmonids and bull trout, inwater construction work will take place during the approved work window from July 16 to December 31. Overwater work can proceed outside of the inwater work window. MSB.A Di Cerchio/ Barbee Mill Waterfront LLC Joint -Use Pier Project• 8 B. Indirect Effects: Indirect effects are effects of the project that occur later in time. For this project, indirect effects might include alteration of juvenile salmon migratory pathways, increase in salmonid predation and reduction in prey resources and refugia due to shading of the epibenthic substrate by the structure. Migratory pathway alteration: Freshwater: There were no studies specifically investigating the effects of piers on salmonid migration in lakes cited by Kahler et al. (2000) in their review of pier -related impacts in lakes. Concerning the lake environment, Kahler et al. (2000) state. "The question remains whether juvenile salmonids in lakes migrate under, or otherwise utilize, piers, or if they avoid them and/or traverse their perimeter." However, more recent reports have provided additional information concerning salmon responses to overwater structures. Tabor and Piaskowski (2002) noted that, "In February and March, chinook salmon were found using overhead structures (piers, docks, and overhanging vegetation) during the day but in April and May, no chinook salmon were ever observed using overhead structures. At night, chinook salmon rarely used overhead structures." The authors hypothesized that the overhead structures were being used as a substitute for natural overhead cover during the days in February and March. In a later study, Tabor et al. (2006) noted slightly different results. They state that, "When migrating Chinook salmon approach a pier they appeared to move to slightly deeper water and either pass directly under the structure or swim around the pier. Most likely they move to deeper water as a way of reducing their predation risk." The pier where these findings we made is approximately 7.8' wide, 138' long and had solid decking. The dimensions of the piers in the earlier study are not known. The results from the later study were noted in May and July, whereas the 2002 study results were for the earlier months of February and March. In a later study, Tabor et al. (2011) reported that. "Juvenile Chinook salmon were rarely observed under an overwater structure during either daytime or nighttime." There were no details concerning the type of overwater structure where these observations were made — sold decking or grated overwater structures. The results of Celedonia et al. (2008) were si milar to those of Tabor et al. (2000). Celedonia et al. stated, "Juvenile Chinook salmon generally avoided areas directly beneath overwater structures. However, areas along the edges of structures (within about 2 in horizontal distance) were sometimes used for prolonged periods (up to 2 hours in one case)." However, these authors offered the following qualifying statement: These observations may be representative of holding fish near structures in general, but may not be an accurate indication of how untagged Chinook salmon would generally behave upon volitionally entering these specific areas. Actively migrating fish (i.e., most fish released off-site and observed at the Seattle Tennis Club site) often appeared to change course as they approached a structure. Structure width and water depth appeared to influence degree of avoidance. Fish appeared less hesitant to pass beneath narrow structures. Fish also appeared to move into deeper water to travel beneath or around structures. These authors also observed: Behavior at structures differed (i.e., swim beneath or travel around perimeter), and may have been related to such interrelated factors as: fish size, light levels beneath the structure, degree of contrast at the light - dark edge, width of the structure, height of the structure above the water surface, and water column depth beneath the structure. Further study is needed to conclusively determine how these and other factors interact to influence Chinook salmon behavior. Marine Waters: In the marine environment, it is generally accepted that overwater structures can alter migration behavior of juvenile salmon (though the effects may vary depending on the design and orientation of the structure, degree of shading, and the presence of artificial light), and reduce salmon prey resources and refugia by shading aquatic plant life (Simenstad et al. 1999; Nightingale and Simenstad 2001 b). However, the MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Projects 9 MS&A significance of these effects is not clear. As Simenstad et al. state, "We found no studies that described empirical evidence supporting or refuting that modification of juvenile salmon behavior in shoreline habitats was reflected in changes in survival." Nightingale and Simenstad (2001 b) state, "Presently, although we know that under some conditions small juvenile salmon will delay or otherwise alter their shoreline movements when encountering an overwater structure, the conditions under which this behavioral modification is significant to the fishes' fitness and survival is relatively unknown." A study by Williams et al. (2003) at the Mukilteo ferry terminal, found that, "Salmon fry were observed in all nearshore habitats during each transect sampling period (day and night). The fry were observed under a wide range of PAR values (0.0 µmol m-2 s-1 to 2370 µmol m-2 s-1). Fry were observed both outside the terminal and underneath the terminal at all times, and shadows produced by the 10 -m -wide terminal structure did not appear to act as barriers to fry movement at this location." There is no question that underwater structures may alter migration patterns —that is not in dispute. As seen in the study by Williams and in many other studies (see the literature review by Weitkamp - 2003), there are studies that indicate that salmon migration is not affected by the presence of overwater structures. Of course, there are other studies indicating migration patterns are altered by overwater structures. The issue is that no one has shown that these migration changes lead to increased mortality or decreased fitness. None of the studies that report changes in salmonid migration patterns caused by overwater structures in the marine environment have reported that these changes have a negative impact on salmonids. Increased predation: An additional concern about the impacts of overwater structures on migrating salmon is that they will be forced to move out into deeper water. where they will be consumed by predatory fish species. However, in a study conducted in the marine environment, Williams et al. (2003) noted: We found no evidence that avian, marine mammal, or fish predators consumed more juvenile salmon near WSF terminals than along shorelines without overwater structures. Few species appeared to be targeting abundant fry in nearshore habitats, and we observed only two occasions in which predators (one tern sp., one staghorn sculpin) had consumed juvenile salmon. The authors also state, Our analysis of fish diets at the Mukilteo ferry terminal provides one piece of conclusive evidence that juvenile salmon were not a major dietary component of predatory fish species during our study. It should be noted that the Williams study was conducted in the marine, not lake, environment. In Lake Washington, smallmouth bass migration into the littoral zone corresponds with the peak occurrence of migrating salmonids in this zone (Fresh et al. 2001). Because of these similar migration patterns, salmonids are most at risk of predation from smallmouth bass in Lake Washington. Bass prefer complex, natural cover for their foraging environment. When there is a scarcity of natural cover for foraging, as is the situation in Lake Washington, they tend to use the dominant structures in the environment, such as pilings and piers, for foraging cover (Kahler et al. 2000). There is concern that increasing the number of overwater structures will increase the predation success of smallmouth bass on migrating salmonids. Tabor et al. (2004) investigated predation ofjuvenile Chinook salmon in three areas of the Lake Washington Basin. One of the areas they looked at was the south end of Lake Washington, an important rearing area. The investigators found that: The only predators observed to consume Chinook salmon were cutthroat trout, prickly sculpin (C aspen), smallmouth bass (Micropterus dolornieui), and largemouth bass (M salmoides). Consumption of Chinook salmon by cutthroat trout was observed in February, March and early April. Predation by prickly sculpin was only observed in February. Smal [mouth bass consumed Chinook salmon in May and June. Few largemouth bass were collected; however, we did document a largemouth bass that had consumed a Chinook salmon in June. We estimated a total of 1,400 Chinook salmon fry were consumed by littoral predators from February to mid May..... Based on consumption estimates and expected abundance of juvenile Chinook salmon, predatory fishes probably consumed less than 10% of the fry that entered the Di Cerc hio/ Barbee Mill Waterfront LLC Joint -Use Pier Project* 10 lake from the Cedar River. The investigators in this study did not comment on the impacts of overwater structures on the predation rate found in south Lake Washington. C. Interrelated/Interdependent Effects: Completion of this project will not promote future construction or other activities that would not otherwise occur without its completion. Therefore, no additional interrelated or interdependent actions that could affect species regulated under ESA will occur because of this project. D. Take Analysis: "Take" is defined as, "to harass, harm, pursue.. hunt, shoot, wound, trap, capture, collect or attempt to engage in any such conduct." The USFWS further defines "harm" as "significant habitat modification or degradation that results in death or injury to listed species by significantly impairing behavioral patterns such as breeding, feeding, or sheltering." It is likely that no "take" will result from this project. E. Conservation Measures: In order to minimize any direct effects on the listed species caused by this project, inwater work should take place between July 16 and December 31. It is requested that overwater work be allowed to take place outside of this work window. Additional impact reduction and mitigation measures will reduce adverse impacts of the project. They include: 1. The first 40' of the fully grated pier will only be 4 -feet wide. 2. Only two 4" diameter steel pilings will be used to support the first 41' of the pier to minimize migration obstacles for young salmonids that prefer the more shallow areas. 3. The construction barge will not be allowed to ground out on the lake bottom at anytime. 4. Piles will be driven using a vibratory pile driver to practical refusal. 5. Construction will take place during authorized in water work windows designed to protect listed species and/or critical habitat. 6. Twent-two shrubs will be planted in addition to the existing native plants seen in Figures 6 and 7. F. Determination of Effect: After reviewing the appropriate data and surveys, the effect determinations for the impacts of the project, as designed, are: 1. Puget Sound chinook —"May affect, not likely to adversely affect" 2. Bull trout —"May affect, not likely to adversely affect" 3. Puget Sound steelhead —"May affect, not likely to adversely affect" 4. Marbled murrelet — "No effect" This is the appropriate conclusion when effects on the species and their critical habitat are expected to be beneficial, discountable or insignificant. Limiting construction work to the approved work window will reduce direct impacts on the listed species. Shading impacts on the benthic environment will be minimized by the conservation measures discussed above.

Essential Fish Habitat Assessment A. Background The Magnuson -Stevens Fishery Conservation and Management Act (MSA), as amended by the Sustainable Fisheries Act of 1996 (Public law 104-267), requires Federal agencies to consult with NMFS on activities that may adversely affect designated Essential Fish Habitat (EFH) for the relevant species. According to the MSA, EFH means "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." For the Pacific West Coast, the Pacific Fisheries Management Council (Council) has designated EFH for federally managed groundfish (PFMC 1998a), coastal pelagic (PFMC 1998b) and Pacific salmon fisheries (PFMC 1999). The purpose of the EFH Assessment is to determine the effects of the proposed project on the EFH for the relevant species and to recommend conservation measures to avoid, minimize or otherwise offset adverse effects on EFH. B. Identification of EFH The designated EFH for groundfish and coastal pelagic species encompasses all waters from the mean high water line, and upriver extent of saltwater intrusion in river mouths, along the coasts of Washington, Oregon and California, seaward to the boundary of the U. S. exclusive economic zone (370.4 km) (PFMC 1998a, 1998b). The designated EFH in estuarine and marine areas for Pacific salmon species extends from the nearshore and tidal submerged environments within state territorial water out to the full extent of the exclusive economic zone (370 .4 km) offshore of Washington, Oregon and California north of Point Conception to the Canadian border PFMC, 1999). Freshwater EFH for Pacific salmon includes all those streams, lakes, ponds, wetlands and other water bodies currently, or historically accessible to salmon in Washington, Oregon, Idaho and California, except areas upstream of certain impassable man-made barriers, and longstanding, naturally -impassable barriers. Chinook salmon and coho salmon are the species with designated EFH that are found in Lake Washington C. Proposed Action The details of the proposed project are presented in section of the attached BE/Lake and Stream Study Report. D. Effects of the Proposed Action The effects of this project on designated EFH are likely to be similar to the effects described in detail in the Effects Analysis section of the attached BE/Lake and Stream Study Report. The project is likely to have no permanent, long -terns effects EFH designated for Chinook and coho salmon. E. EFH Conservation Measures The conservation measures mentioned in the attached BE/Lake and Stream Study Report will be implemented to minimize possible adverse effects to EFH. F. Conclusion The project may have temporary adverse effects on EFH the salmon species, but will not produce long-term adverse effects on EFH for the above species.

Assessment of Impacts to Critical Habitat for Puget Sound Chinook Project description: Construction of a new community -use dock on Lake Washington in Renton, This assessment covers the primary constituent elements (50 CFR Part 226, page 74581-2) determined essential to the conservation of Puget Sound Chinook salmon (Oncorhynchus tshawytscha): (1) Freshwater spawning sites with water quantity and quality conditions and substrate supporting spawning, incubation, and larval development. Existing Conditions: There are no suitable freshwater spawning sites at the project location. (2) Freshwater rearing sites with water quantity and floodplain connectivity to form and maintain physical habitat conditions and support juvenile growth and mobility; water quality and forage supporting juvenile development; and natural cover such as shade, submerged and overhanging large wood, logjams and beaver dams, aquatic vegetation, large rocks and boulders, side channels, and undercut banks. Existing Conditions: Native vegetation has been planted immediately landward of the bulkhead in conjunction with the upland development. There is a concrete/rock bulkhead along the shoreline of both properties. No side channels or undercut banks were noted. (3) Freshwater migration corridors free of obstruction with water quantity and quality conditions and natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, side channels, and undercut banks supporting juvenile and adult mobility and survival. Existing Conditions: See (2) above. (4) Estuarine areas free of obstruction with water quality, water quantity and salinity conditions supporting j uvenile and adult physiological transitions between fresh -and saltwater; natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, and side channels, and juvenile and adult forage, including aquatic invertebrates and fishes, supporting growth and maturation. Existing Conditions: See (2) above. (5) Nearshore marine areas free of obstruction with water quality and quantity conditions and forage, including aquatic invertebrates and fishes, supporting growth and maturation; and natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulder and side channels. Existing Conditions: The site is in a freshwater area. (6) Offshore marine areas with water quality conditions and forage, including aquatic invertebrates and fishes, supporting growth and maturation. Existing Conditions: The site is in a freshwater lake area. MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project 28 , w 4P Effects Analysis: A complete discussion of the effects of this project is seen in the BE/Lake and Stream Study Report. Construction will produce brief and localized increased turbidity, which will be contained by a silt curtain. The project will have no long-term impacts on water quantity, salinity conditions or water temperature. Construction during work windows will prevent impacts to the listed fish species. Shading impacts on the benthic environment will be reduced by design components of the proposed project. The entire dock will be fully grated. Only two 4" diameter steel pilings will be used to support the first 41' of the pier to minimize migration obstacles for young salmonids that prefer the shallowest areas. The construction barge will not be allowed to ground out on the lake bottom at anytime. Additional native vegetation will be planted. Determination of Effect: "May affect, not likely to adversely affect" MS&A DiCerchio/Barbee Mill Waterfront LLC Joint -Use Pier Project 29 W Y Attachment 5. Assessment of Impacts to Critical Habitat for Coastal - Puget Sound Bull Trout Applicant: Richard DiCerchio The primary constituent elements determined essential to the conservation of bull trout (Salvelinus confluentus) are: (l) Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures from 32 to 72 °F (0 to 22 °C) but are found more frequently in temperatures ranging from 36 to 59 °F (2 to 15 °C). These temperature ranges may vary depending on bull trout life history stage and form, geography, elevation, diurnal and seasonal variation, shade, such as that provided by riparian habitat, and local groundwater influence. Stream reaches that preclude bull trout use are specifically excluded from designation. Existing Conditions: The project will take place in Lake Washington, a large body of fresh water. Effects to PCE: The project is not expected to have any influence on the water temperature of Lake Washington. (2) Complex stream channels with features such as woody debris, side channels, pools, and undercut banks to provide a variety of depths, velocities, and in stream structures. Existing Conditions: Project will take place in Lake Washington - not in a stream environment Effects to PCE: No effect (3) Substrates of sufficient amount, size and composition to ensure success of egg and embryo overwinter survival, fry emergence, and young -of -the year and juvenile survival. This should include a minimal amount of fine substrate less than 0.25 in (0.63 cm) in diameter. Existing Conditions: No spawning activity at the site Effects to PCE: No effect (4) A natural hydrograph, including peak, high, low. and base flows within historic ranges or, if regulated, currently operate under a biological opinion that addresses bull trout, or a hydrograph that demonstrates the ability to support bull trout populations by minimizing daily and day-to-day fluctuations and minimizing departures from the natural cycle of flow levels corresponding with seasonal variation: This rule finds that reservoirs currently operating under a biological opinion that addresses bull trout provides management for PCEs as currently operated. Existing Conditions: Project will take place in Lake Washington Effects to PCE: The project does not involve any alteration in the lake level; therefore it will have no impact on this PCE. MS&A Di Cerchio/ Barbee Mill Waterfront LLC Joint -Use Pier Project* 30 (5) Springs, seeps, groundwater sources, and subsurface water to contribute to water quality and quantity as a Cold- water source. Existing Conditions: See 4 above Effects to PCE: This project will have no impact on springs, seeps, groundwater sources or subsurface water (6) Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows. Existing Conditions: Native vegetation has been planted along the site shoreline. Effects to PCE: The proposed dock will incorporate design components that will decrease negative impacts on foraging habitat and migratory corridors. The proposed dock will be fully grated. (7) An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish. Existing Conditions: Native vegetation has been planted along the site shoreline. Effects to PCE: See 6 above (8) Permanent water of sufficient quantity and quality such that normal reproduction, growth and survival are not inhibited. Existing Conditions: See 4 above. Effects to PCE: Pile driving may produce temporary turbidity impacts. These are expected to be short term and are not expected to have a significant impact on critical habitat. Any debris associated with the project construction phase will be contained by a silt containment curtain. Determination of Effect: "No destruction or adverse modification" Conservation Measures: Conservation measures for this project are seen in the BE/Lake and Stream Study Report.
