Washington Department of Natural Resources Derelict Creosote Piling Removal Best Management Practices For Pile Removal & Disposal The following Best Management Practices (BMPs) are adapted from EPA guidance (2005), Washington State Department of Transportation (WSDOT) methods and conservation activities as included in Joint Aquatic Resources Protection Application (DARPA), 2005, and Washington State Department of Resources (W ADNR) "Standard Practice for the Use and Removal of Treated Wood and Pilings on and from State -Owned Aquatic Lands" 2005, as well as WADNR's practical experience through managing piling removal. proj ects since 2006. The purpose of these BMPs is to control turbidity and sediments re-entering the water column during pile removal, and prescribe debris capture and disposal of removed piles and debris. BMP 1. PILE REMOVAL Crane operator shall be experienced in pile removal. Piles will be removed slowly. This will minimize turbidity in the water column as well as sediment disturbance. Pulled pile shall be placed in a containment basin to capture any adhering sediment. This should be done immediately after the pile is initially removed from the water. A. Vibratory extraction 1) This is the preferred method of pile removal. Vibratory extraction shall always be employed first unless,the pile is too decayed or short for the vibratory hammer to grip. After consultation with WADNR, the alternative options listed below may be used. 2) The vibratory hammer is a large mechanical device (5-16 tons) that is suspended from a crane by a -cable. The hammer is activated to loosen the piling by vibrating as the piling is . pulled up. The hammer is shut off wben the end of the piling reaches the.rnudline. Vibratory extraction takes approximately 15 to 30 minutes per piling depending on piling length and sediment condition. 3) Operator will "Wake up" pile to break up bond with sediment. • Vibrating breaks the skin friction bond between pile and soil. • . Bond Breaking avoids pulling out a large block of soil —possibly breaking off the pile in the process. • Usually there is little or no sediment attached to the skin of the pile during withdrawal. 1n some cases material may be attached to the pile tip, in line with the pile. B. Direct Pull 1) This method is optional if the contractor determines it to be appropriate for the substrate type, pile length, and structural integrity of the piling. Vibratory extractor must be attempted fast unless there is risk of greater disturbance of sediments. Updated 3/19/2013 2) Pilings are wrapped with a choker cable or chain that is attached at the top to a crane. The crane pulls the piling directly upward, removing the piling from the sediment. C. Clamshell Removal 1) Broken and damaged pilings that cannot be removed by either the vibratory hammer or direct pull may be removed with either a clamshell bucket or environmental clamshell. 2) A clamshell is a hinged steel apparatus that operates like a set of steel jaws. The bucket is lowered from a crane and the jaws grasp the piling stub as the crane pulls up. 3) The size of the clamshell bucket shall be minimized to reduce turbidity during piling removal. 4) The' clamshell bucket shall be emptied of material onto a contained area on the barge before it is lowered into the water. D. Cutting 1) Is required if the pile breaks at or near the existing substrate and cannot be removed by other methods. 2) If a pile is broken or breaks above the mudline during extraction, all of the methods listed below should be used to cut the pile. a. The pile should be cut 1 foot below the mudline. b. Piles shall be cut off at Iowest practical tide condition and at slack water. This is intended'to reduce turbidity due to, reduced flow and short water column through which pile must be withdrawn. c. - In subtidal areas, if the piling is broken off at or below the mudline, the piling may remain. In intertidal areas, seasonal raising and lowering of the beach could expose the pilings above the mudline and leach out PAH's or other contaminants. In this case, the piling should be cut off at least one root below the mudline. d. No hydraulic jetting devices shall be used to move sediment away from piles. e. The contractor shall provide the location of all the broken and cut piles using a GPS. BMP 2. BARGE OPERATIONS; WORK SURFACE, CONTAINMENT A. Barge grounding will not be permitted. B. Work surface on barge deck or pier, or upland staging area shall include a containment basin for all treated materials and any sediment removed during pulling. Creosote shall be prevented from re-entering the water. Uncontaminated water run-off can return to the waterway. Updated 3/19/2013 1) Containment basin shall be constructed of durable plastic sheeting with continuous sidewalls supported by hay bales, ecology blocks, other non -contaminated materials, or support structure to contain all sediment and creosote. Containment basin shall be lined with oil absorbent boom. 2) Work surface on barge deck and adjacent pier shall be cleaned by disposing of sediment or other residues along with cut off piling as described in BMP #43. 3) Containment basin shall be removed and disposed in accordance with BMP 44.B or in another manner complying with applicable federal and state regulations. 4) Upon removal from substrate the pile shall be moved expeditiously from the water into the containment basin. The pile shall not be shaken, hosed -off, left hanging to drip or any other action intended to clean or remove adhering material from the pile. BMP 3. DEBRIS CAPTURE IN WATER A. A floating surface boom shall be installed to capture floating surface debris. The floating boom shall be equipped with absorbent pads to contain any oil sheens. Debris will be collected and disposed of along with cut off piling as described in BMP #4. B. The boom may be anchored with four or fewer % ecology blocks or a similar anchoring device. These anchors must be removed once the project is complete. The anchor system shall be located to avoid damage from vessel props to eelgrass, kelp, and other significant macroalgae species. The line length between the anchor and surface float shall not exceed the water depth as measured of extreme high tide plus a maximum of 20 percent additional line for scope. The buoy system shall include a subsurface float designed to keep the line between the anchor and surface float from contacting the bottom during low tide cycles. The subsurface float shall be located off the bottom a distance equal to 1/3 the line length C. The boom shall be located at a sufficient distance from all sides of the structure or piles that are being removed to ensure that contaminated materials are captured. The boom shall stay in its original location until any sheen present from removed pilings has been absorbed by the boom. BMP #3B may be used to keep the boom in its original location. D. Debris contained within boom shall be removed at the end of each work day or immediately if waters are rough and there is a chance that debris may escape the boom. F. To the extent possible all sawdust shall be prevented from contacting beach, bed, or waters of the state. For example, sawdust on top of decking should be removed immediately after sawing operations. F. Any sawdust that enters the water shall be collected immediately and placed in the containment basin. G. Piles removed from the water shall be transferred to the containment basin without leaving the boomed area to prevent creosote from dripping outside of the boom. Updated 3/19/2013 BMP 4. DISPOSAL OF PILING, SEDIMENT AND CONSTRUCTION RESIDUE A. Piles shall be cut into lengths as required by the disposal company. B. Cut up piling, sediments, absorbent pads/boom, construction residue and plastic sheeting from containment basin shall be packed into container. For disposal, ship to an approved Subtitle D Landfill. C. Creosote -treated materials shall not be re -used. BMP 5. RESUSPENSIONITURBIDITY A. Crane operator shall be trained to remove pile from sediment slowly. B. Work shall be done in low water and low current, to the extent possible. C. Removed piles shall be placed in a containment facility. D. Sediments spilled on work surfaces shall be contained.and disposed of with the pile debris at permitted upland disposal site. E. Holes remaining after piling removal shall not be filled. BMP 6. PROJECT OVERSIGHT A. WADNR will have a project manager or other assigned personnel on site. Oversight responsibilities may include, but -are not limited to the following: 1) Water quality monitoring to ensure turbidity levels remain within required parameters 2) Ensure contractor follows BMPs 3) Ensure contractor is in compliance with contract and permit requirements 4) Ensure correct structures are removed 5) Maintain contact with regulatory agencies should issues or emergencies arise BMP 7. CULTURAL RESOURCES A. In the event that artifacts (other than the pilings or materials attached to them) that appear to be 50 years old or older are found during the project, the WADNR Aquatics archaeologist must be notified in order to evaluate the find and arrange for any necessary consultation and mitigation required by law. B. If human remains or suspected human remains are found during the project, work in the vicinity will be halted immediately, and the County Coroner must be notified immediately. if Updated 3/19/2013 the remains are determined to be non -forensic, then the WADNR Aquatics archaeologist will be notified to begin tribal and Washington State Department of Archaeology and Historic Preservation consultations required by law, C. If sediment exceeding 1 cubic meter is removed, the WADNR Aquatics archaeologist will be notified and given the opportunity to examine the sediment for cultural materials before it is removed from the containment area.

The permits are approved subject to conditions. Testimony Clark Close, City of Renton Senior Planner, summarized the staff report. Michael Lloyd, applicant representative, noted that the applicant has recently acquired approval from the Army Corps of Engineers for the option of disposing dredge materials in Elliot Bay. However, the preferred disposal option is beneficial re -use in road projects and the like as opposed to dumping the dredge materials into Elliot Bay. Mr. Lloyd explained the dredging is necessary to access the boathouse. It's difficult to estimate the amount of material that needs to be dredged because of the unpredictability of May Creek and what it will deposit near the boathouse. The name of the permit is misleading because no fill is involved.

A hearing on the applications was held on April 18, 2017 in the City of Benton City Council meeting chambers at Renton City Hall, 14 11 Substantive: 15 l[d 17 18 19 20 21 22 23 24 25 26 3. Description of Proposal. The applicant has applied for a Special Fill and Grade Permit and a Shoreline Substantial Development Permit to do some dredging in Lake Washington near the May Creek Delta to clear away sediment deposition from May Creek that is blocking access to a boathouse and shared use dock serving four homes in Eagle Cove. Approximately 2,500 to 4,000 CY would be dredged during each dredging event. In recent history, the area was dredged in 1994, 1997, 2001/2002, and 2011. The proposed dredging project is estimated to be required every 3-5 years. The proposed project site is located from 3905 Lake Washington Blvd N to the boat house just north of 3979 Lake Washington Blvd N (APN's 3342700011, -0009, -0007, -0005, and 0518501150) in Renton, WA. The dredging and mitigation work is anticipated to be conducted in two phases and potentially a third, beginning in 2017. The applicant is proposing to continue periodic dredging of depositional sediments that have accumulated within Lake Washington, near the May Creek Delta, for a period of 10 years for a maximum of three phases of dredging. The proposed profile is not anticipated to reach depths that would encounter sediments that are older than dredging work completed in 2011 or in previous dredging events. Dredge work would require approximately 80 hours over a 10-day period. 4. Adverse Impacts. There are no significant adverse impacts associated with the proposal as mitigated. Pertinent impacts are individually addressed as follows: A. Ecological Function. The proposal will result in no net loss of ecological function. This SPECIAL GRADE/FILL PERMIT AND SSDP - 2 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 conclusion was reached in a lake study, Ex. 13, prepared by Meridian Environmental, Inc.. The conclusions of the lake study were based upon a detailed and thorough review of environmental impacts and application of numerous studies based upon best available science. As to background conditions, numerous salmonid species have been documented at or near the proposed project site, including coho, Chinook, and sockeye salmon. The salmonids are listed in the Washington State Department of Wildlife Priority Habitats and Species data base. Other fish such as bass perch, rainbow trout/steelhead and cutthroat trout have also been documented near the project site. Six species of aquatic macrophytes have also been documented in the project vicinity. With recommended mitigation measures, the study concluded that the proposal would maintain and possibly improve water quality; enhance aquatic habitat and hydraulic functions in lower May Creek; slightly increase primary productivity and near -shore habitat quality in Lak Washington; and reduce predation in the project area. Based on these factors, the lake study concluded that the proposal would create no net loss of shoreline ecological functions. A biological assessment was also prepared for the project, Ex. 12. The biological assessment identified that the chinook salmon, steelhead and bull trout are documented at the project area and are listed as threatened under the ESA and that the coho salmon are classified as a species of concern. The biological assessment concluded that with recommended mitigation the proposal "may affect," but is "not likely to adversely affect" Chinook, steelhead, and bull trout. As to impacts to fish habitat, the study concluded that with recommended mitigation that water quality would improve; primary productivity and fish forage base would be improved; and shoreline and instream habitat quality would be improved. There is no evidence in the record that is contrary to the conclusions and analysis of the lake study and biological assessment. The two studies were very thorough, based upon best available science and professionally done. The mitigation measures recommended in the studies are imposed by the MDNS. From these studies and the mitigation measures it is concluded that the proposal will not result in a net loss of ecological function. B. Stormwater. There will be no unpermitted runoff, including stormwater at the project dredge area. The proposal would not alter or otherwise affect drainage patterns in the vicinity of the site. C. Noise. The applicant has indicated that operation of dredging equipment and upland heavy equipment (frontend loaders, etc.) would generate expected noise levels during construction of up to 80 to 90 decibels on a short-term basis only during construction. No long-term noise levels would be created. Construction noise would only occur during SPECIAL GRADE/FILL PERMIT AND SSDP - 3 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 daylight hours. The short 10-day dredging period dictates the impacts would be temporary. No unusual noise impacts are proposed, which would require further levels of noise mitigation. To ensure that the public is notified of the proposed dredging activities in a timely manner, a condition of approval requires that the applicant develop a public notification plan complete with temporary signage, subject to approval of staff. D. Aesthetics. The staff report does not identify the aesthetic impact of the proposal. It appears from the staff report that the equipment will be limited to a barge. Considering the short ten day dredging period, it is determined that the presence of a barge along the shoreline will not create any unreasonable unsightliness or significant adverse aesthetic impacts. E. Traffic. As mitigated, the proposal will not create any significant traffic impacts. The applicant has specified that the disposal of the excavated sediment would be transported one of three ways: hauled off -site, off-loaded at a site on Lake Washington, or open water/ocean disposal. if either of the first two ways are selected for handling sediments, a detailed Traffic Control Plan would need to be submitted and approved by the City of Renton prior to the start of construction. F. Navigation/Public Access/Recreation. The proposal will significantly improve navigation, recreation and public shoreline access near the applicant's boathouse and community dock by removing sedimentary obstacles to boat passage, consistent with its purpose. Conclusions of Law � Procedural: 1. Authority of Hearing Examiner. RMC 4-9-080(F)(1)(a) provides that the hearing examiner is responsible for granting permits for fill and grade that involves excavation of more than 500 cubic yards. The proposal dredging will involve at least 2,000 cubic yards. Shoreline substantial development permits are classified by RMC 4-8-080(G) as Type 11 permits (subject to staff as opposed to hearing examiner review). The shoreline permit of this case has been consolidated with the special grade and fill permit review as Type III review overall pursuant to RMC 4-8-080(C). Substantive: 2. Applicable Standards. RMC 4-9-080(F)(4) governs the criteria for special fill/grade permits. The criteria for shoreline substantial development permits is set by RMC 4-9-190(B)(7), which requires compliance with all City of Renton Shoreline Master Program ("SMP") use regulations and SMP policies. Applicable standards are quoted below in italics and applied through corresponding conclusions of law. SPECIAL GRADE/FILL PERMIT AND SSDP - 4 2 3 4 5 6 7 8 9 10 I 12 13 14 15 16 17 is 19 20 21 22 23 24 25 26 Fill and Grade Permit RMC 4-9-080(F)(4): ...To grant a special permit, the Hearing Examiner shall make a determination that.. the proposed activity would not be unreasonably detrimental to the surrounding area. The Hearing Examiner shall consider, but is not limited to, the following: i. Size and location of the activity. ii. Traffic volume and patterns. lit. Screening landscaping, fencing and setbacks. iv. Unsightliness, noise and dust. v. Surface drainage. vi. The length of'time the application of an existing operation has to comply with nonsafety provisions of'this Title. 3. The primary impact of concern would be impacts to sensitive environmental resources. As determined in Finding of Fact No. 5, the proposal will not result in a net reduction of shoreline ecological function. Other pertinent impacts are also addressed in Finding of Fact No. 5 to the extent relevant to the criterion quoted above. Since none of the impacts qualify as significantly adverse, the criterion is met. Shoreline Permit RMC 4-9-190(B)(7): In order to be approved, the Administrator of'the Department of Community and Economic Development or designee must find that a proposal is consistent with the following criteria: a. All regulations oJ ' the Shoreline Master Program appropriate to the shoreline designation and the type of use or development proposed shall be met, except those bulk and dimensional standards that have been modified by approval of a shoreline variance. b. All policies of the Shoreline Master Program appropriate to the shoreline area designation and the type of use or development activity proposed shall be considered and substantial compliance demonstrated. A reasonable proposal that cannot fully conform to these policies may be permitted, provided it is demonstrated to the Administrator of the Department of'Community and Economic Development or designee that the proposal is clearly consistent with the overall goals, objectives and intent of the Shoreline Master Program_ c. For projects located on Lake Washington the criteria in RCW 90.58.020 regarding shorelines of statewide significance and relevant policies and regulations of the Shoreline Master Program shall also be adhered to. SPECIAL GRADE/FILL PERMIT AND SSDP - 5 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 4. The proposal meets the criterion quoted above for the reasons identified in Finding No. 22 of the staff report, adopted by this reference as if set forth in full. The staff report does not directly address the shoreline of statewide significance policies of RCW 90.58.020, but those policies are clearly met since as determined in Finding of Fact No. 5 of this decision the proposal will result in no net loss of shoreline ecological function, the proposal will not adversely affect navigation or shoreline public access and the proposal will not create any adverse impacts to the shoreline environment. DECISION The grade/fill permit and ssdp are in conformance with all applicable review criteria for the reasons identified in the Conclusions of Law. The two permits are approved subject to the following conditions: 1. The applicant shall comply with the mitigation measures issued as part of the Determination of Non -Significance Mitigated, dated March 6, 2017. 2. To ensure that the public is notified of the proposed dredging activities in a timely manner, the applicant shall develop a public notification plan complete with temporary signage. The Plan shall be reviewed and approved by the Current Planning Project Manager prior to the commencement of the maintenance dredge work. 3. The applicant shall submit existing topography of the lake bed prior to each dredging event and final dredging contours and cross -sections of the lake bed after each dredging event. The plan shall be reviewed and approved by the Current Planning Project Manager prior to construction permit approval. 4. The applicant shall submit copies of any and all permits and associated documents issued from other State and/or Federal permitting agencies to the Current Planning Project Manager. 5. The applicant shall submit a restoration plan if off -site hauling results in any shoreline bank impacts. The plan shall be reviewed and approved by the Current Planning Project Manager prior to construction permit approval. 6. The Shoreline Substantial Development Permit and Special Fill and Grade Permit shall remain effective for a permit not to exceed 10 years from the date of approval or until such time as the City of Renton adopts new shoreline regulations. 7. The use of land vehicles for disposal of sediments shall be subject to a detailed traffic control plan approved by the City of Renton prior to the start of construction. Decision issued May 392017.

Our project team viewed the comments as constructive. Your letter is provided in Attachment A to this response 1. What is the total duration of this dredging proposal? The NOA describes an every 3-5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year; however, there is no information far phase 2 and how the 10 year request was derived. Response to Comment_ 1. The Lake Houses at Eagle Cove (hereafter, Owners) have requested a 10 year permit from the City of Renton to conduct Sediment Deposition Mitigation dredging. If all permits are obtained and the Owners can proceed with Environmental Enhancement work and mitigation dredging, this first phase of the work will be completed this summer. The second phase of sediment mitigation dredging will likely occur within the next 5 years of the requested 10 year permit. Because of weather, particularly severe storm events, and unpredictable deposition patterns, there is a potential for a third dredging event. A ten year permit has been requested because the Owners have no illusions that excessive sediment deposition from the May Creek Valley will be corrected any time soon by local government. Until such measures are implemented to mitigate upstream erosion, the Owner's problem will not go away. This is why we have requested a 10 year permit. 2. More information is needed regarding the full extent of dredging_ The checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. Response to Comment 2. Sediment Deposition Mitigation, LUA16-000977, ECF, SM Currently, applicant has obtained a 10 year permit from the USACE to maintain navigational access in the northern portion of the project area which impacts the Boathouse lot (parcel: 0518501150), Lot A (parcel: 3342700005), and a major portion of Lot B (parcel: 3342700007). Lot A (parcel: 3342700005) and a major portion of Lot B (parcel: 3342700007 have received the most sediment deposition in recent years to compromise navigational access. In reviewing cross sections presented in Sheets 3 and 4 of the application, Lot C (parcel: 3342700009) and Lot D (parcel: 3342700011) have not been impacted to an extent that dredging will be required in 2017, Likewise, we do not anticipate having to dredge a lot of sediment at the boathouse parcel in the near term. It is not a case of determining if sediment deposition will occur, but when. Ignoring the impact of severe storm events, changing weather (global warming), and unpredictable sediment deposition patterns is a major mistake in planning for the future. Therefore, we have included Lots C and D in our proposed work area. If the Owners never have to conduct sediment deposition mitigation dredging in Lot C (parcel: 3342700009) and Lot D (parcel: 3342700011), then so much the better. The major impact is to navigational access to the boathouse which is nearly blocked at this point in time. Until such time that the existing USACE permit is amended or a new permit obtained, mitigation dredging for the near term will be limited to what has been approved by the USACE, even after a new 10 year permit is secured from the City of Renton. Given that sediment deposition from the May Valley is a dynamic process (and unlikely to be corrected any time soon), estimating future sediment loadings by parcel is not possible given the unknowns of weather, sediment deposition rates, deposition directions and locations, as well as estimating the effectiveness of proposed measures to mitigate deposition. Although our focus is currently on being able to mitigate sediment deposition this summer to restore navigational access in the northern portion of the site, predicting the future is a difficult task with the exception of knowing that deposition will likely continue to occur for the duration of the 10 permit request to the City of Renton. 3. It is our understanding that a 10 year dredging permit was issued and modified for parcel 0518501150 (Cugini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. Response to Comment 3. The previous permits issued by the City of Renton, the Corps, WDFW, and Ecology includes the Boathouse parcel, Lot A and part of Lot B. Because the City of Renton permit expired in October 2016, it is essential to include these parcels in this permit request. 4. As part of the Notice of Application, City staff" indicated that the dredging work may inadvertently spill over onto the May Creek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in Lake Washington. Response to Comment 8 continued . As typically conducted, dredging will occur from deeper water to more shallow water to provide access for barge mounted equipment. At no time will dredging occur from the land with the Lloyd & Associates, Inc. Page 2 of 8 Sediment Deposition Mitigation, LUA16-000977, ECF, SM potential for "spill over" to the May Creek Delta parcel. It is worth noting that we have proposed leaving a shelf of approximately 4-6 feet wide from the northern property line which will not be dredged. This area is being set aside for environmental enhancement/mitigation to provide a base for install root wads as shown in Sheet 5 of the application. Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specifically stated that the dredging a 10, 000 square foot area by 2 feet every 3-5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the fallowing: 4a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented. An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; Res once to Comment 4a. Project completion reports were submitted to the USACE and the City of Renton for dredging and environmental mitigation work conducted in 2011. Because of the expansion of the area of highest sedimentation, the USACE amendment of 2016 (expanding the permitted dredge area) was requested by project proponent. This amendment was approved in light of, and in consideration of previous public comment, with the prerequisite that mitigation measures be completed in the amended USACE permit which will run until 2026. These mitigation/ environmental enhancement measures were approved by the City of Renton as a Shoreline Exemption and have been incorporated into our current application request to the City of Renton. 4b. A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown; and Response to Comment 4b. Bathymetry work conducted in 2016 was provided in our application to the City of Renton (provided as Sheet 1). Since dredging in 2011, there has been some infill to the immediate boathouse area, although substantial subsequent deposition has compromised access west and southwest of the boathouse at Lots A and B. An interim completion report was submitted to the City of Renton in September 2011. A copy is provided in Attachment B. This report documents environmental enhancement measures completed and environmental compliance with fish protection measures. The May Creek Delta was not dredged for a number of reasons: (1) our permit request to dredge the May Creek Delta was withdrawn in response to comments from the USACE (and other inputs) and (2) changed circumstances as a consequence of sale of the delta property in 2007. As there was no requirement at the time for a bathymetry submittal to the USACE, this was not submitted. The current USACE permit does have a hydrographic survey commitment which we will comply with for both pre and post -dredge survey results. Lloyd & Associates, Inc. Page 3 of 8 Sediment Deposition Mitigation, LUA16-000977, ECF, 5M 4c. The location and success of previous mitigation measures for the previously permitted dredging work. Response to Comment 4c. Previous mitigation and environmental enhancement measures were completed as noted in Attachment B, summarized in the Interim Completion report: • Placement of fish rock to enhance the near shore shallow water habitat with more fish friendly materials, • Removal of failing creosote and rotted untreated pilings in the boathouse area and replacing with galvanized steel piles, • Removal wood and metal debris, and rotting wood/leaf debris that depletes dissolved oxygen in the water column, • Replacement of approximately 150' of solid surface floats with a single 40' float with grated surface for greater light transmission to the shallow water habitat, and • Shoreline enhancements for near shore plantings were completed in previous years, preceding dredging and boathouse re -construction in 2011 (see completion photographs in the interim completion report, Attachment B). 5. Also parcel 3342700009 (3907 Lake Washington Blvd N) currently does not have a dock or any structure that provides moorage. Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of important shallow water habitat for juvenile salmon as the moorage needs can be accommodated by other means (Le. expansion of existing joint moorage facilities, buoys, etc.). Response to Comment 5. Lot C does not have a dock or structure that provides moorage. However, the dock installed at Lot D is a shared -use dock for the Lake Houses at Eagle Cove. Nevertheless, the comment is valid if one assumes that future sediment deposition, arising from May Creek will not occur. This is a bad assumption. There is no near -term plan to dredge this area in 2017. However, predicting future depositional patterns is simply not possible. In the event that future storm events deposit a large volume of sediment cascading into Lot C and potentially Lot D further south, the applicant needs to have the option in approved permitting to dredge, if necessary, to maintain the current recreational uses at this location. It is worth mentioning, the applicant is not in love with the concept of having to mitigate sediment deposition, arising from poor erosion control measures beyond the applicants control. The guiding principal for dredging is to dredge as little as possible to maintain recreational uses and enjoyment. The costs to dredge are substantial. Secondly the transactional costs (permitting at local, state and the federal level) is staggering. This is not an exercise undertaken lightly. 6. Please provide additional information regarding the necessary navigational depth profile for each parcel. This information should be presented parcel by parcel in a table. Response to Comment 6. Sheets 1 and 2 of our application submittal provide the current (2016) existing and proposed depth profiles across the entire project area. Sheets 3 and 4 provide cross sections across all parcels in the project area. There is no expectation that dredging will be required in Lots C and D in 2017, although this could change with just one huge storm. We fully expect that winter storms of 2016- Lloyd & Associates, Inc. Page 4 of 8 Sediment Deposition Mitigation, LUA16-000977, ECF, SM 2017 have further modified the existing condition. This is why we have proposed conducting both pre- and post -dredge surveys to accommodate the dynamic nature of sediment deposition. Presenting the dredge data parcel by parcel appears to be unnecessary at this time. The bulk of near term dredging (proposed for 2017) will impact Parcels A and northern portion of Parcel B as permitted by USACE. Minor dredging in the Boathouse parcel may be required, depending on sediment deposition during the rainy season of 2016 and 2017. Dredging will not occur south of the approved USACE dredge limits until such time an amended or a new permit is secured from USACE and dredging permit limits are reconciled. 7. Please provide monitoring data from previous dredging work. It is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. Response to Comment 7. Based on previous turbidity monitoring results and the sandy nature of sediments to be dredged, there was no expectation of turbidity plumes. Nevertheless, visual monitoring was conducted by the contractor and by Michael Lloyd, Lloyd & Associates throughout the work. At no time was there any evidence of turbidity as is noted in the Interim Completion Report submitted to the City of Renton and the USACE in 2011. Likewise, salmon were not observed in the project area during the approved "fish" window at any time during the work in the summer of 2011 It is worth noting that the project proponents, specifically Meridian Environmental, advised USACE of the need to cease dredging beyond September 15 to avoid the potential presence of salmon that have been observed in the project area in October and following months. 8. One document that was sent via email with the Notice of Application is the Biological Assessment dated August 27, 2012 is for the dredging at the Boathouse parcel (0518501150); the parcel immediately south 3342700005 (3979 Lake Washington Blvd N); and a portion of parcel 3342 70000 7 (3909 Lake Washington Blvd N). It does not cover dredging at the other parcels noted in the master Iand use application or NOA. Response to first part of Comment 8. While the Biological Assessment (BA) does not directly address the effects of the proposed expanded dredge prism on ESA listed species and their habitat, the conclusions reached in the BA are directly applicable to the parcels referenced in your above comment. As noted in Meridian's 2016 Lake Study, the substrate located throughout the proposed expanded dredge prism is a mixture of silt and sand, riprap cobble, leaf litter, and fish rock patches. Riprap cobble, sand, and gravel were the dominant substrates located within 6 feet of the shoreline to a depth of approximately 3 feet. Sand was the dominant substrate within and near the delta to a depth of about 6 feet, and silt and organic debris (e.g., leaf material) were the dominant substrates along the remaining transects. Aquatic macrophytes in the proposed expanded dredge prism include elodea (Elodea Canadensis), Eurasian milfoil (Myriophyllum spicatum), and curly -leaf pondweed (Potamogeton crispus). Both Eurasian milfoil and curly -leaf pondweed are non-native species, and Eurasian milfoil has colonized a large percentage of the littoral zone and replaced much of the native aquatic vegetation present in littoral areas of Lake Washington. While no fish were observed during the 2016 Lake Study's winter SCUBA survey, numerous salmonid species have been documented at or near the proposed project site over the past 23 years, including coho, Chinook, and sockeye salmon, rainbow trout/steelhead, and cutthroat trout (Harza Engineering Company 1993; Harza Engineering Company 2000; Meridian Environmental, Inc. and Harza Engineering Company 2001; Meridian Environmental, Inc. 2005; Meridian Environmental, Inc. Lloyd & Associates, Inc. Page 5 of 8 Sediment Deposition Mitigation, LUA16-000977, ECF, SM 2007; and Meridian Environmental, Inc. 2012). In the south end of Lake Washington (including the proposed expanded dredge prism), fry of these species tend to prefer shallow, near -shore habitat with sand and gravel substrates, and are typically associated with overhanging brush and emergent vegetation. Water depths within the proposed expanded dredging zone range from 3 to 25 feet. This area is generally deeper than those preferred by rearing salmonid fry, and all dredging would occur within the NMFS approved work window (July 16 — September 15) when juvenile salmon and steelhead are not anticipated to be present in the project area. It unlikely that juvenile and adult salmonids would come in direct contact with the dredging equipment, or that they would be physically injured or killed by the dredging activities. In addition, it is very unlikely that the short-term and localized increases in turbidity generated by the proposed project would rise to the levels that would be expected to cause harm to salmonids that may be present in the dredging zone. Overall, periodic maintenance dredging in the proposed expanded dredge prism coupled with the protection and enhancement measures outlined in the 2016 Lake Study are expected to preserve navigational access to Owner's docks and boathouse; maintain and possibly improve water quality conditions in the project area; enhance aquatic habitat and hydraulic functions in lower May Creek; slightly increase primary productivity and near -shore habitat quality in Lake Washington; and reduce predation in the project area. Consequently, the proposed expanded dredge prism project is likely to have a negligible effect on ESA listed and non -ESA listed salmon species in Lake Washington, and no net loss of shoreline ecological functions will result from the proposed project.

Additional Response to Comment S. As typically conducted, dredging occurs from deeper water to more shallow water to provide access for barge mounted equipment. At no time will dredging occur from the land with the potential for "spill over" to the May Creek Delta parcel. It is worth noting that we have proposed leaving a shelf approximately 4-6 feet wide on the northern property line which will not be dredged. This area is being set aside for environmental enhancement/mitigation to provide a base to install rootwads, as proposed in Sheet 5 of the application. The rational for including parcels 3342700009 (3907 Lake Washington Blvd N) and 3342700011 (3905 Lake Washington Blvd N) were included in the proposal was addressed in response to Comment 4, preceding. 9. The assessment regarding potential salmon impacts as described in the 2012 Biological Assessment is based on limited information (Le. Tabor et at 2004). Much more research data and information has been collected since this and should be used in a revised Biological Assessment or another environmental assessment format. See httE //www.govlink org/watersheds/8/pdf/LArGI Salmon,Syn123108-pdf ht ://www ovlink.o /water sheds/8/ d /RTabor-Seattle-mt-12-08-2010, d and other reports by Roger Tabor and other scientists are available. Response to Comment 9. In reviewing the referenced information, we found that juvenile Chinook salmon that enter Lake Washington as recently emerged fry use the lake as rearing habitat for 1 to 4 months (from early February to late May) before migrating to the marine environment. During the day they appear to prefer shallow (less than approximately 1.6 feet deep) near shore habitat with woody debris and overhead cover. However, at night they tend to move away from woody debris and into more open water areas. When fry use deeper waters, they are larger in size, deep water prey resources are available, and littoral zone temperatures are higher. Newly emerged Chinook fry also appear to prefer sand, gravel, and cobble substrates near tributary deltas and shorelines with no armor, and avoid over -water structure. Use of creek deltas (e.g., May Creek delta) is highest in February and March, and decreases completely by late June. As juvenile Chinook salmon increase in size, they tend to avoid overhead cover. During May few Chinook use overhead and small woody debris during either daytime or nighttime. However, juvenile Chinook may occasionally use small woody debris and overhead vegetation for cover when predators are present. Similarly, larger juvenile Chinook tend to avoid docks and piers and will move into deeper water as they approach overwater structures. The Chinook salmon that rear for a few months in their natal streams and enter the lake later in the spring generally spend just a few weeks in shallow -water areas before moving out into deeper water. Juvenile Chinook salmon typically migrate out of the Lake Washington basin between late May and early July, with a peak in June. Similarly, when sockeye fry first enter the lake environment, they may inhabit shallow water areas such as river deltas at night. Sockeye fry are also commonly found in other parts of the littoral Lloyd & Associates, Inc. Page 7 of 8 Sediment Deposition Mitigation, LUA16-000977, ECF, SM zone the actual amount of time fry are present in this area is not known. Most of the time sockeye fry travel in schools in limnetic areas below 66 feet. Not much information is known about the habitat use of coho salmon and steelhead in Lake Washington. Both are thought to enter Lake Washington at a larger size, which would influence their preferred habitats. In Lake Sammamish, however, coho salmon fry (likely hatchery fry released from Issaquah Hatchery) exhibited habitat use patterns similar to those of Chinook fry; however, they were more strongly affiliated with woody debris. 10. Please provide additional discussion and figures showing where and what mitigation was required and completed from the previous dredging permits. Response to Comment 10. Completed mitigation for work conducted in 2011 is provided in the Interim Completion Report for in -water work (see Attachment B). The only item that was incomplete is the replacement float adjacent to the shoreline. This work was carried over to our amended permit by the USACE along with additional environmental enhancements/mitigation, as was recently approved by the City of Renton. This work has been proposed to be conducted in the first year after approval of the requested permits from the City of Renton. 11. The Sediment Sampling and Analytical Results report.

During our review, staff has determined that additional information is necessary in order to proceed further. The fallowing information will need to be submitted before May 3, 2017 so that we may continue the review of the above subject application: On January 27, 2017, Karen Walter with the Muckleshoot Indian Tribe Fisheries Division provided agency comments regarding the subject application. Given the site -specific and potential cumulative impacts to juvenile Chinook and ether sairnon species from this project, it is essential that these data/information and project detail gaps be addressed prior to the City's completion of environmental review to avoid further permitting and project details. At this time, the project has not demonstrated a "no -net loss" in part because of these data and information gaps. The questions raised by the Muckieshorat Indian Trine Fisheries Division have been modified slightly to give you opportunity to comment on each question. 1, What is the total duration of this dredging proposal The NOA describes are every 3-5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year, however, there is no information for phase 2 and how the 1.0 year request was derived. 1055 South Grady Way, Renton, VIA 93057 w rentonwa,gov 2. More information is needed regarding the full extent of dredging. The checklist describes dredging 2,5t10 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel, the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. 3. It is our understanding that a 10-year dredging permit was issued and modified for parcel 0518501150 (Cuigini Boathouse) was already issued by the City, the Carps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. As part of the Notice of Application, City staff indicated that the dredging work may inadvertentty spill over onto the May Creek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in lake Washington, Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specifically stated that the dredging a 10,000 square foot area by 2 feet every 3-5 years with some variation clue to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with: other actions. Since this time, the boathouse parcel, 0518501150, requested a Carps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the fallowing: a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging: permits have been fully implemented.

Essentially, their work was conducted in two steps. Major subsystems of the platform (often referred to as the ring) were constructed at Seidelhuber Steel in Seattle. Otto Rosenau inspectors inspected welds and materials during platform construction. When the frame sections were galvanized, they were transported by flat barge to the Cugini site for final assembly and welding into place on top of driven piles (Attachment ). As noted. in .inspection reports, corrective actions were completed as required. Also attached is a copy of the Interim Completion Report, recently provided to the U.S. Arty Corps of Engineers (Atta.chrncnt 3), The boathouse is not complete, but all in - water work for the boathouse is done.

The design approved by the City of Renton called for a total of 12 bide -flange beams driven to refusal to carry the new building loads- Six piles were located on each of the north and south sides of the new boathouse. A minimurn of 15-foot embedment into dense soils was required by the structural engineer to achieve sufficient vertical capacity and lateral bending resistance. Representatives from our firm observed the installation of the piles on July 25 through 27, 2011, Pacific Piling utilized a large vibratory hammer to install the H-piles vertically. As required by the plan, galvanized W1474 beams were installed for the boathouse. Through observation of the penetration rate, we were able to verify that all piles were installed to at least 15 feet of embedment into the dense soils. The pile lengths necessary to reach sufficient embedment increased from east to west, as was expected. Based on our observations, it is our professional opinion that file piles were driven an acceptable manner and reached sufficient embedment into dense soils to support the design loading.

Page 2 of 21 Barbee Maintenance Dredging and Boathouse Renovation Project Interim Completion Report - September 9, 2011 1.0 Scope of Work - Summary The construction objective during the in -water work window was to complete maintenance dredging, place clean sediments upland at Quendall Terminals, demolish the old boathouse, dispose of all debris, install piling, and complete installation of the boathouse platform (frequently referred to as the "ring'). In addition to dredging and boathouse construction work, habitat enhancements were also completed. Habitat enhancements included: • Placement of fish rock along rockeries to enhance the near shore shallow water habitat with more fish friendly materials. • Removal of failing creosote and rotted untreated pilings in the boathouse area and replacing this piling with galvanized steel piles, • Dredging of sunken logs, metal debris, and rotting wood/leaf debris that depletes dissolved oxygen in the water column, • Replacement of approximately 150' of solid floats with a single 40' Moat with grated surface for greater light transmission to the shallow water habitat, and • Shoreline enhancements for near shore plantings were completed in previous years, preceding dredging and boathouse re -construction. To the right is a photograph taken in 2007 prior to shoreline plantings, and construction work described in this report. The land -mark "green" boathouse has been demolished. Existing conditions, prior to work recently completed, are shown in Figure 1-1 on the following page. These photographs span a period of approximately 4 years. Lloyd & Associates, Inc.

Initially, the navigational channel was dredged by Pacific Pile and Marine (PP&M) to provide access to the boathouse. The approved area was dredged to an elevation of approximately 10' (MSL) as shown in project plans. Actual elevations achieved varied between elevation 10' and 11'. Sediments were principally clean, free -draining coarse to fine sands with minimal silt content, as anticipated from Sampling and Analysis results reported in January, 2008 to the USACE. PP&M used an excavator with a closed environmental bucket on a floating barge. Sediments were loadcd onto a flat bermed/lined barge. Water quality during dredging was not impacted beyond the immediate work area because of sandy conditions encountered and the dredging methodology/equipment employed (see Figure 2-1). At no time were salmon present or observed during dredging, although several large carp were observed in the project area. As soon as demolition of the boathouse was completed and pilings were extracted, the boathouse footprint was dredged to complete dredging. Approximately 922 CY of sediment was dredged during this project. 2-1— Photographs taken during dredging Setting op on the moming of July 16, 2011 Dredging access channel. Note absence of turbidity.

Page 6 of 21 Barbee Maintenance Dredging and Boathouse Renovation Project Interim Completion Report - September 9, 201. 1 3.0 Placement at Quendall Terminals Sediments dredged from the project area were placed on a flat barge and allowed to dewater sufficiently for handling and off-loading at Quendall Terminals, approximately 2000' feet north of the project site. Sediments were place in a constructed berm area, as approved by EPA. The bermed area was lined with a permeable geotextile to provide a demarcation between, dredged materials and soils of Quendall Terminals. An excavator on shore stacked the materials, and separated debris from the dredged sediments. Debris from demolition of the boathouse was also placed at Quendall. Demolition debris and segregated dredged debris was loaded into containers. Containers were hulled off site directly from Quendall Terminals for disposal at an approved landfill. Quendall Terminals provided a very good location to offload dredged sediments and demolition debris. The access area at the southern portion of Quendall Terminals was also used as a loading area for materials used at the site. The site has good access and sufficient depth for shallow vessels to approach the shoreline for loading. Clean sediments from the dredge area will likely be used as cover/fill during the cleanup of Quendall Terminals.

Page 8 of 21 4.0 Boathouse Demolition and Piling Removal Demolition of the old green boathouse went fairly rapidly. Supporting piles were substantially rotten and the structure came down without any problems. A debris boom was enclosed the demolition area to contain floating debris. All debris was placed on a flat barge and offloaded into containers at Quendall Terminals. The structure contained no indications of any insulating materials. Following demolition, the boathouse footprint was dredged to remove any demolition debris that may have sunk to the bottom and to meet depth requirements. All demolition and dredging debris was hauled offsite for disposal in an approved landfill. As soon as the boathouse was demolished, piling was pulled and loaded onto the flat barge. Eighteen piles were removed from the boathouse footprint and another 7 piles were removed at dolphins in the boathouse approach. A total of 25 piles were removed. Extracted Piles were a mixture of creosote and "barkies". Approximately 50% of the piles were treated creosote piles. Pictures shown in Figure 4-1 show the demolition of the boathouse and pile removal.

Page 10 of 21 Barbee Maintenance Dredging and Boathouse Renovation Project Interim Completion Report - September 9, 2011 5.0 Habitat Enhancement Numerous habitat enhancements have been completed during this phase of the work. Habitat enhancements include: • Placement of fish rock along rockeries to enhance the near shore shallow water habitat with more fish friendly materials. • Removal of failing creosote and rotted untreated pilings in the boathouse area and replacing this piling with galvanized steel piles, • Dredging of sunken logs, metal debris, and rotting wood/leaf debris that depletes dissolved oxygen in the water column, • Replacement of approximately 150' of solid floats with a single 40' float with grated surface for greater light transmission to the shallow water habitat, and • Shoreline enhancements for near shore plantings were completed in previous years, preceding dredging and boathouse re -construction. In addition to habitat enhancements, the new boathouse structure is more aesthetically pleasing and will be architecturally compatible with surrounding structures when completed. Removal of treated creosote piles is discussed in Section 4.0 - Demolition. Removal of shallow water debris is discussed in Section 3.0 Dredging. Upland habitat shoreline plantings at the boathouse and the little house lot to the south were completed in previous years. Several pictures (before and after) are provided in Figure 5-1. It is worth noting that no shoreline excavation or disturbance occurred at the shoreline at the project site that would have triggered erosion control measures. Fish rock, as approved by Department of Fish & Wildlife was placed at shoreline rockeries as required. Approximately 47 CY of rounded river rock was placed at the rockery to the south and at the immediate area behind the boathouse. Fish rock shallow water habitat enhancement photographs are provided in Figure 5-2 on the following page. Floyd & Associates, Inc.

Page 14 of 21 Barbee Maintenance Dredging and Boathouse Renovation Project Interim Completion Report - September 9, 2011 6.0 Pile Installation Piling for the boathouse was installed as soon as the depth profile was approved. Twelve (12) galvanized steel H-piles (W14x74) were installed, replacing 18 treated/untreated piles. Additionally, 2 galvanized pipe piles were installed to replace a creosote dolphin and a single treated pile. Piling locations were set by Touma Engineers. Pile installation was also observed by Geotech Consultants, geotechnical special inspectors for the City of Renton. All piles were driven with a vibro-hammer to proscribed depth or refusal. The depth of refusal occurred within the compacted glacial till as anticipated, in agreement with geotechnical work conducted in January, 2010. An impact hammer was not required. Because of the difficulty in driving H-piles into alignment, pile locations did vary. 6-1— Pilina Installation First pile being lined up Driving the first pile Lloyd & Associates, Inc.

Page 16 of 21 Barbee Maintenance Dredging and Boathouse Renovation Project Interim Completion Report - September 9, 2011 7.0 Boathouse Frame Construction The boathouse frame was constructed at Seidelhuber Steel (Seattle, WA). A photograph below shows the platform under construction in their shop prior to galvanizing. The framework was modified to facilitate construction off -site, provide a stronger structure, and to simplify assembly in the field. The frame was brought in on a flat barge in three sections, and lofted into place with a barge -mounted crane. The structure was squared and tack welded until final welds were completed. The platform matches project plans for length and width. Finally, the new boathouse structure was raised to provide a minimum of 18" of clearance above the Ordinary High Water Line (OHWL = 21.85'). The galvanized deck grating was installed with minor changes to increase grating support. Finally a 4"x 12" rub rail was installed, and a white molded rubber finish rail was installed to protect moored boats. Ten cleats were bolted through the frame to provide secured tie up, and a rub wheel was installed at the front of the boathouse structure to facilitate entry to the boathouse. Otto Rosenau, Inc provided inspections for work conducted at Seidelhuber Steel's facility. Otto Rosenau, Inc. was the special inspector for structural/welding for the City of Renton. When the steel structure was set in place, final welds in the field were inspected by Otto Rosenau, Inc. to assure compliance with welding requirements and structural integrity requirements. Corrective action for several welds, as required by the inspector, was completed to the inspector's satisfaction. Figure 7-1 provides a number of photographs for setting the steel frame, and welding the frame to pile cap plates. Finally, Marine Floats installed the new float to replace existing floats demolished during demolition. Several pictures are provided in Figure 7-2. Lloyd & Associates, Inc.

Page 20 of 21 Barbee IVtaintenance Dredging and Boathouse Renovation Project Interim Completion Report - September 9, 201 l 8.0 Work to Be Completed/Conclusions This initial phase of the work covered dredging, sediment placement, and construction of the boathouse frame. Work was completed prior to the closure of the in -water work window (September 15, 2011). The boathouse superstructure was not completed during this phase of the work. Until such time as the superstructure is completed, the boathouse frame will provide uncovered. In addition to completing the superstructure, dredging will have to be completed again in the access/navigational channel in the next few years under existing permits because of continued sediment deposition in the May Creek area. Regulatory Cooperation We appreciate the patience and professionalism that has been provided to our project team. In particular, special thanks go to the City of Renton, U.S. Army Corps of Engineers, Washington State Department of Fisheries, and the Department of Ecology. The boathouse renovation has been a long time coming, and there have been many changes since the initial conception in 2005. Need for Controlling Sediment Deposition from the May Valley The rapidly accreting May Creek Delta is anticipated to grow substantially in the next few years. An estimated 20,000 CY of material has eroded since the delta was last dredged in 2002 with an average deposit of approximately 2,200 CY per year. Absent any changes, this pattern of substantial erosional runoff will continue or potentially accelerate in the future from developmental pressures in the May Valley. Lloyd & Associates, Inc.

In recent history, the area was dredged in 1994, 1997, 2001/2002, and 2011. The proposed dredging project is estimated to be required every 3-5 years in order to maintain and preserve navigational access to the boathouse, shared use dock, and recreational access to Lake Washington for four (4) single-family residences (Lake Houses at Eagle Cove). Approximately 2,500 to 4,000 CY would be dredged during each dredging event. The proposed project site is located from 3905 Lake Washington Blvd N to the boat house just north of 3979 Lake Washington Blvd N (APN's 3342700011, -0009, -0007, -0005, and 0518501150) in Renton, WA. Within Lake Washington, dredging work may also spill over onto the May Creek Delta parcel (APN 0518500000), located just north of the project site. The parcels are zoned Residential-6 (R-6) and Residential-10 (R-10). The dredging and mitigation work is anticipated to begin in the summer of 2017.

The subject property is located at the NW intersection of Sunset Blvd NE and NE 7th St within the NE of Sections 8, Township 23 North, Range 05 East, W.M. King County, Washington (Exhibits 2 and 3). The western boundary of the site is roughly 200 feet east of 1-405. The 39,187 square foot property proposed for development of Sunset's Edge Townhomes abuts the west side of Sunset Blvd NE and is just north of NE 7th St. Surrounding the 39,187 square foot property proposed for development of Sunset's Edge Townhomes is single family home and Crystal Heights Townhomes Condominium consisting of 18 units to the north, Puget Sound Energy property to the west and south, and two single family homes across Sunset Blvd NE to the east. The property has a Comprehensive Plan land use designation of Residential High Density (RHD), is zoned Residential Multi -Family (RMF) and is located in the Urban Design District B overlay district. The applicant is proposing attached residential dwellings, which are an allowed use in the RMF zone. The land surrounding the site is zoned RMF to the north, R-1 to the west and R-8 to the south and east. The RMF zone has an allowed density up to 20 dwelling units per net acre. The proposal consists of 15 units to be constructed as four (4) buildings; consisting of four (4) different building types in duplex and 5-plex configurations (Exhibit4). Proposed building "Type A" would make up 3 units, "Type B" would make up 5 units, "Type C" would make up 6 units, and "Type D" would make up 1 unit (Exhibit 5). Building 1 consists of 3 units, Buildings 2 and 4 consist of 5 units each and Building 3 consists of 2 units. Together the units would have a finished gross floor area of 34,795 square feet (living area + garage area + deck area; Exhibit 4). The average living area per unit is approximately 1,756 square feet with an average attached garage size of approximately 467 square feet. The smallest overall unit would have a total finished living area of 1,745 square feet with a 214 square feet attached garage and a 44 square feet deck area (2,003 square feet). The largest overall unit would have a total finished living area of 1,678 square feet with a 728 square feet attached garage and a 136 square feet deck area (2,542 square feet). Each unit would have attached parking garages on the first level providing stalls for two vehicles with either side -by -side or tandem parking (Exhibit 6). If all 15 units are provided by the development, the net density would be 17.5 dwelling units per net acre, which is within the allowable density range for the RMF zone. These buildings would be approximately 37'-2 A" at the highest point of the shed roof and three stories (Exhibit 7). The proposed development plans to take advantage of territorial views to the West while maintaining inviting and pedestrian -oriented facades along Sunset Blvd NE. All buildings facing Sunset Blvd NE are configured to have large glass entry doors on raised stoops. The site was previously improved with a small 480 square feet office building with paved and gravel access drive. Fill was also placed on the property to create a terraced area more or less even with Sunset Blvd NE. The office building was removed in 2010; however, the pavement and gravel areas remain in an unmaintained condition. The remainder of the site is covered by trees, blackberry bushes, and grass.

Frontage requirements include 22-foot wide half -street paved width from the centerline of the right-of-way (including five-foot wide bike lane, eleven -foot wide thru travel lane, and six-foot wide half width for the center turn/ left turn lane), one-half foot wide curb, eight -foot wide landscaped planter strip, eight -foot wide concrete sidewalk, and one -foot wide clear width back of the sidewalk. The right-of-way (ROW) width should extend to include the one -foot wide clear width back of the sidewalk. The ROW width dedication required is approximately 9.5 feet (subject to final survey). Additional improvements to the site include subgrade utility installation, driveways, a woonerf, landscaping, pedestrian pathways, retaining walls, and common open space. The project would access Sunset Blvd NE via a new private driveway extending west into the site, approximately 83 feet, before configuring into a T-shaped hammerhead turnaround. Vehicular access to the proposed buildings would come from a central private road. As proposed, there are 30 parking spaces provided within the garages and 1 outside surface parking stall near the common play area. The total impervious surface area would be approximately 21,161 square feet or 56.8 percent of the net lot area (21,161 SF / 37,244 SF = 56.8%). Pervious areas of the project site would either be landscaped or installed with pervious pavers.

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 applicant submitted Geotechnical Engineering Report for 701 Sunset Blvd NE prepared by E3RA, Inc. (dated April 16, 2015; Exhibit 10). At total of three exploratory test pits were excavated with a rubber -tracked mini -excavator. The subsurface soils on the site were found to contain a surface mantle of sod, topsoil, or gravel surfacing, typically no more than 6 inches thick. Underlying this material, a fill zone spans much of the site, typically extending to 4% feet below existing grade. The uppermost 3 feet of the fill material is comprised of silty sand in a medium dense in -situ condition. From 3%to 4'/ feet below existing grade, logs, woody debris and general refuse were incorporated into the fill material. Native soils on site consist of glacial till deposited during the most recent glaciation of the area; the Vashon Stade of the Fraser Glaciation. Glacial till deposits observed in our subsurface explorations were all moderately weathered and comprised of gravelly, silty sand in a medium dense in -situ condition, The report stated that unweathered deposited would likely be encountered with depth. No groundwater seepage was observed by the geotechnical engineer at the time of subsurface explorations (January 21, 2015), which extended to a maximum depth of 7 % feet below existing grade. The geotechnical report did not encounter any loose sand layers or tenses that could contribute to liquefaction. The geotechnical report concludes post -construction settlement could occur due to a zone of organic -laden fill material underlying the site. As a result, the geotechnical report recommends over -excavation of the building footprints down to native soils (approximately 4 % feet) followed by structural fill. Also, if floor construction occurs during wet conditions, it is likely that a geotextile fabric, placed between the structural fill floor subbase and native soils, would be necessary. In addition, conventional spread footings were also found, by the geotechnical engineer, to provide adequate support for the structures if the subgrades are properly prepared. The applicant proposes to excavate approximately 900 cubic yards of fill material and native soils. Structural fill is estimated to be approximately 3,400 cubic yards. Overall the applicant is proposing to regrade approximately 75 percent of the subject property to provide for building sites, access driveways, common ERC Report Oty of Renton Department of Community & Economic Development Environmental Review Committee Report SUNSETS EDGE TOWNHOMES LUA16-000864, ECF, PP, PPUD Report of February 27, 2017 Page 5 of 8 open space and parking areas. The applicant would be subject to designing and installing temporary erosion and sedimentation control measures (TESC) in order to capture runoff water and sediment during construction. The subject property has been identified as an Erosion Hazard and Landslide Area by City of Renton G15, based on the much of the site slopes exceeding 15%. A protected slope exists along the western margin of the site. According to the geotechnical report and the results of the soil exploratory test pits, past fill activity spans much of the site, typically extending to 4 Y1 feet below existing grade. A protected slope is defined as a hillside, or portion thereof, with an average slope, as identified in the City of Renton Steep Slope Atlas or in a method approved by the City, of forty percent (40%) or greater grade and having a minimum vertical rise of fifteen feet (15'). The engineer identified a 5,485 square font area of the subject property as protected slopes. The applicant is proposing to encroach into approximately 2,025 square feet of the protected slope necessitating an alteration to the critical areas created as a result of the private gravel U-shaped road installation created over the past several decades. The applicant is proposing to remove the existing fill comprised of silty sand, logs, woody debris and general refuse up to 4 Y2 feet below grade from the top of the protected slope and re -graded to less than 15 feet in vertical rise so that relief of the protected slope would be less than 15 feet high (Exhibit 13). Therefore, staff is recommending a mitigation measure that would require the applicant to formally apply for a Critical Area Variance, from RMC 4-3-050, Critical Areas Regulations in order to encroach into the protected critical slope or apply for a modification to alter the geologically hazardous critical area in accordance with RMC 4-3-050J, prior to civil construction permit approval. The Geotechnical Report, recommends that no permanent slopes be steeper than 2H:1V and all permanent cut slopes and fill slopes should be adequately inclined to reduce long-term raveling, sloughing, and erosion. The use of flatter slopes (such as 2Y1H:1V) would further reduce long-term erosion and facilitate revegetation. The 2015 geotechnical report included specific recommendations for: site preparation, spread footings, slab - on -grade floors, asphalt pavement, and structural fill. As such, staff recommends a mitigation measure that the applicant shall comply with the recommendations found in the Geotechnical Engineering Report completed by BRA, Inc. (dated April 16, 2015) or updated report submitted at a later date. Mitigation Measures: a. Project construction shall be required to comply with the recommendations found in the Geotechnical Engineering Report completed by BRA, Inc. (dated April 16, 2015) or updated report submitted at a later date. b. The applicant shall apply for a Critical Area Variance, from RMC 4-3-050, Critical Areas Regulations, in order to encroach into the protected critical slope or apply for a modification to alter the geologically hazardous critical area in accordance with RMC 4-3-050J, prior to civil construction permit approval. Nexus: State Environmental Policy Act (SEPA) Environmental Review, RMC 4-3-050 CriticaiAreas Regulations and RMC 4-4-060 Grading, Excavation and Mining Regulations. 2, Air Impacts: It is anticipated that some temporary adverse air quality impacts could be associated with site work and building construction required to develop this site. Project development impacts during construction may include dust as a result of grading and exhaust from construction vehicles. Dust control would be mitigated through the use of temporary erosion control measures or other measures to remediate impacts as needed (Exhibit 15). No further site specific mitigation for the identified impacts from typical vehicle and construction exhaust is required.

Water runoff (including stormwater) Impacts: Duncanson Company, Inc. submitted a Preliminary Technical Information Report for Sunset's Edge Townhomes (dated October 26, 2016; revised date January 27, 2017; Exhibit 11) with the application. The report analyzes off -site drainage and project surface water collection and distribution. According to the report, project site basin area is 37,244 square feet or 0.86 acres. Water runoff exits the property and flows northwest through Puget Sound Energy (PSE) property, down a well vegetated slope of less than 15 percent, for at least 50 feet. Runoff continues west for another 200 feet before entering the stormwater conveyance system in 1-405. According to the drainage report, the site was previously graded and filled. The project is part of a redevelopment of the site that removes and replaces some pavement and gravel areas with the construction of 15 townhouse units. A new internal road and sidewalk is proposed to provide access to the units. Runoff would be collected from the access drive, roof surfaces and some landscape areas and would be routed to a subgrade detention tank (shown on the generalized utilities and drainage plan - C1 measuring roughly 38 feet long by 35 feet wide; Exhibit 13) near the north end of the subject property via a piped storm drainage system. The proposed control flow rates would match the existing conditions for the 2-,10-, and 100-year storm events. As described in the drainage report, full dispersal is not considered feasible due to lack of available flow paths and infiltration was also deemed infeasible due to fill and till soils and slope considerations. Flow control BMPs are proposed to take the form of permeable pavers for the internal site walkways. The project would provide Basic Water Quality treatment in the form of a Stormfilter and provide for Peak Rate Flow Control according to the TIR. Mitigation Measures; No further mitigation recommended. Nexus: N/A 4. Vegetation impacts; An Arborist Report was prepared by Arborists NW, LLC (dated October 30, 2016; Exhibit 12) and was submitted with the land use application. The subject property contains 16 significant trees, with the predominant species being cottonwood. Other tree species identified by the report included Big Leaf Maple, Black Locust, Pine, and Sweet Gum with a Diameter Standard Height (DBH) ranging from 8 to 55 inches. The applicant is required to retain 20 percent (20%) of the trees located onsite that are not located within the proposed rights -of -way or access easements. Of the 16 significant trees within the project area, the applicant is proposing to retain 5 trees to meet the 20% tree retention requirement (Exhibits 8, 9 and 12). As a result, the applicant has demonstrated compliance with the Tree Retention requirements of the code. During construction, trees required to be retained (i.e., protected trees), would be required to comply with the tree protection measures during construction per RMC 4-4-130H.9. The eight central components of tree protection include defining and protecting the drip line, erecting and maintaining a temporary six -foot - high chain link construction fence with placards around the tree to be retained, protecting the tree from grade changes, keeping the area clear of impervious surface material, restricting grading within the drip line, providing three inches (3") of bark mulch within the required fencing, retaining a certified arborist to ensure trees are protected from development activities, and alternate protection/safeguards as necessary. Mitigation Measures: No further mitigation recommended. r:RC Report City of Renton Department of Community & Economic Development Environmental Review Committee Report SUNSET'S EDGE TOWNHOMES LUA16-000864, ECF, PP, PPUD Report of February 27, 2017 Page 7 of 8 Nexus: N/A 5. Environmental Health a, Noise Impacts: Noise impacts would primarily result from the construction of the proposed road improvements and new structures. The construction noise would be regulated through the City's adopted noise level regulations per Chapter 8-7, RMC. The City's noise regulations limit haul hours between 8:30 am to 3.30 pm, Monday through Friday unless otherwise approved by the Development Services Division. Permitted work hours in or near residential areas are restricted to the hours between seven o'clock (7:00) a.m. and eight o'clock (8:00) p.m. far multi -family construction activities from Monday through Friday. Work on Saturdays is restricted to the hours between nine o'clock (9:00) a.m. and eight o'clock (8:00) p.m. No work is permitted on Sundays. Noise impacts anticipated are anticipated to be impacts that would be commonly associated with multi- family development. Mitigation Measures: No further mitigation recommended. Nexus: N/A 6. Aesthetics Impacts: The 3-story duplex and 5-plex multi -family buildings would be setback from the public right-of-way approximately 10 feet (Exhibit 4). The development transition between the existing development to the north and the proposed multi -family structures are buffered by the landscaped public amenity area at the NE and NW corners. The four townhornes the located near the north property edge have sloped shed roofs that open the development and reduce the massing along the property edge. The building massing is also articulated with balconies, designed to enhance building composition and provide amenity space. Composite siding with textured cement would make up the exterior building materials. The project proposes to utilize the BuiltGreen sustainable rating system to minimize the environmental impact of the development. Site infrastructure, such as storm drainage, will be underground and designed in accordance with Low Impact Development principles to allow for increased common open space on the subject property. Mitigation Measures: No further mitigation recommended. Nexus: N/A 7. Transportation Impacts: A traffic impact analysis is required when estimated vehicular traffic generated from a proposed development exceeds 20 vehicles per hour in either the AM (6:00 - 9:00) or PM (3:00 —6:00) peak periods. Generally this includes residential plats of 20 lots or more lots. A residential project consisting of 15 townhome units is not expected to generate more that 20 new peak hour trips (as per the ITE Trip Generation Manual); therefore, a traffic study was not required for the proposed project. It is estimated that there would be between 300 and 430 commercial dump truck trips for import and export of approximately 4,300 cubic yards of graded materials and structural fill to and from the project site. All construction traffic would occur by leaving the site (turning right) and following Sunset Blvd NE to the south. All traffic would then proceed to either turn left onto Maple Valley Highway or 1-405. Access to the site would be provided through a private road located near the center of the site. The central access point minimizes curb cuts onto Sunset Blvd NE, classified as a Minor Arterial Road. The access would terminate in a hammerhead turnaround at the center of the development (Exhibit 5). This would allow for centralization of vehicular access while also allowing sufficient developable area for the project. The ERC Report City of Renton Department of Community & Economic Development Environmental Review Committee Report SUNSET'S EDGE TOWNHOMES LUA16-000864, ECF, PP, PPUD Report of February 27, 2017 Page 8 of 8 neighboring properties have all been developed so it is not anticipated that further development would occur at this intersection. The private internal entrance access driveway would be sloped at a 2 percent grade where it intersects with Sunset Blvd NE, and then it would increase to a 15 percent slope through the middle section before terminating at a 2 percent slope at the centerline of the internal lane. The internal lane has slopes between 6 and 10 percent. Access roads with slopes in excess of 15 percent must be approved by the Renton Fire Authority. The project would be required to complete half -street frontage improvements to Sunset Blvd NE. Street improvements would include, but are not limited to, paving, sidewalks, curb and gutter, landscaping, bicycle lanes, and street lighting along Sunset Blvd NE (Exhibit 13). The internal access road would be constructed as a woonerf (a shared pedestrian and vehicular area). The typical width of the woonerf is 25 feet of asphalt followed by a 4 to 5 foot pedestrian walkway constructed with permeable pavers. The permeable pavers are located in the plaza area between Buildings 3 and 4, on both sides of the woonerf within the north/south portion of the T-shaped hammerhead abutting the lots, in the off-street surface parking stall, along the south side of the entrance road, and in the pedestrian walkways connecting the public sidewalk along Sunset Blvd NE to the front doors of Buildings 1 and 2. The flush curbs between the two different materials would allow shared pedestrian and vehicular movements throughout the development. On -street parking would not be allowed on the portion of Sunset Blvd NE fronting the site or within the proposed private access road. Mitigation Measures: No further mitigation recommended. Nexus: Not applicable. 8. Fire & Police Impacts: Police and Fire Prevention staff indicated that sufficient resources exist to furnish services to the proposed development; subject to the condition that the applicant provides Code required improvements and fees. Mitigation Measures: No further mitigation recommended. Nexus: Not applicable. E. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers.

Each tree on site now sports numbered metal tags (20), 12 trees are slated for removal. 3 trees with DBH's below the required 8" are included on this list as we looked at every tree. These trees are not used in the computations for the "Tree Retention Worksheet" The International Society of Arboriculture Level 1 inspection method was used. Ail trees to be removed, to allow for the proposed development with numerous trees to be replanted. The trees that will remain are relatively young trees and should withstand the exposure clearing will create. The health of the trees is similar, again they are young trees to 40' in height with full if asymmetric crowns. No deadwood was found. These trees are a vigorous species will remain viable for many years. However, as the retained trees are all cottonwoods in the years to come they will pose increasingly elevated risk levels. The reasoning for this is, the species vigorous growth to 160' In height and relatively brittle wood. In advanced years, they are subject to summer limb drop endangering the parking and living spaces. Driplines were determined by visual observation of the existing tree limbs. It will be important to not disturb the root systems of the retained trees. This will start with stump grinding rather than pulling out of stumps for removals located in overlying driplines. After that fencing, shall be installed at the outer limits of the dripline with signs stating that there is to be no excavation, parking, storing of materials or walking inside the protective fencing. There will be little to no adverse effects on trees of the abutting properties as they are already well spaced and away from site boundaries and trees. This isolation will leave the abutting tree roots untouched. The new building when complete will replace the wind screening lost from tree removals. Find listed the species, D88 measurements.

The intent of this document is to clarify some of the measures that will be taken, to ensure that this project does not adversely impact the community, throughout the construction process. Proposed construction dates: Construction is proposed to begin Spring of 2017 and will extend into spring of 2018. Hours and days of operation: Construction will begin at 7:30am-6:00pm, Monday -Friday. Any work that occurs outside of this timeframe will be in accordance with the Renton Municipal Code (RMC). Proposed hauling/transportation routes: All construction traffic will occur by leaving the site (turning right) and following Sunset Blvd NW to the south. All traffic will then proceed to either: turn left onto Maple Valley Hwy and continue on 169 to the west, OR turn left onto Maple Valley Hwy and take the next left onto the onramp for northbound 405, OR continue straight on Sunset which merges into the onramp for southbound 405. Measures to be implemented to minimize dust, mud, noise, and hauling hours: In order to minimize dust and mud being tracked onto Sunset Blvd NW, proper TESL measures will be followed, in accordance with the submitted and approved TESL plan (apart of the Permit drawings)_ The TESL plan will stipulate the location and length of the construction entrance, which is designed to shake off the majority of site dirt/mud that has been affixed to the tires_ if debris is tracked into the right of way, additional measures may need to be taken to remediate dust/mud; including but not limited to: hand sweeping, street sweeping, and wheel washing. All hauling will occur within the hours noted above AND in accordance with Renton Municipal Code. The site will be fenced with signage and Fabric so as to minimize noise, debris, dust, etc from leaving the site and to act as a visual deterrent for passing traffic on Sunset Blvd NW. Please feel free to cell me with any additional questions or concerns.

Planning Review Comments Contact: Clark Close 1425-430-72891 cclose@rentonwa,gov The following Information will need to be submitted before March 13, 2017 so that we may continue the review of the above subject application: Adequate sight distance should be provided at the street intersectlons. The buildings will be required to be located outside the sight triangle lines or clear vision area. Adequate comer curb turning radluses are to be provided at the internal street and alley Intersections to most fire department requirements. Fire department apparatus access roadways are required to be minimum 20 feet wide fully paved, with 25 feet inside and 45 feet outside turning radius. Adequate turning movements for fire vehicles would not Infringe upon pedestrian sidewalks. All Internal roads to serve the Fanned Urban Development projed shall be private alleys located within a tract or tracts, Update the Civil Sheets and the Architectural Sheets to reflect the revised preliminary plat layout. An inverted crown section is to be provided on all private alleys. As a public benefit, staff Is recommending that the alley be constructed Into a Woonerf (living street), which views the street as a social space, or shared space, rather than just a channel for vehicular mobility. The construction details and specification should be shown in the plans. In general, an alley Is constructed of a minimum 4 inches thick HMA over minimum 6 inches of crushed rock for the pavement layer thickness. However, staff Is also suggesting the incorporation of pavers Into the overall design. A Homeowners Association will be required to be established to ensure maintenance and repair of the private alleys, sidewalks and open space Is paid for by the future residents. Update the Draft Legal Documents accordingly. The proposed access location from Sunset Blvd NE (approximately 86 Net north of the south property line to the center of the drive isle) will require the access to be restricted to a right in right out only driveway with c curbing on Sunset Blvd NE (this is because the access is located In the portion of Sunset Blvd which has the left turn only lane marking)_ If the applicant wants the City to review full access for the project, then the access location will have to be proposed further north (away from the end of the left turn only lane on Sunset Blvd NE). It the applicant wishes to proceed with the relocated access option, a revised sketch labeling the distances from the nearby street intersection and from the end of the left turn only lane should be submitted for review. if the driveway access is relocated further to the north, full access to Sunset Blvd NE will require the construction of a two way left turn lane In front of the site. The minimum easement width for water main is 15 feet instead of the 10 feet shown In the current submittal. No buildings or walls are allowed in water easement. In order to meet the Pre flow demand, a minimum 12 inch diameter water main Is required throughout the site Instead of the 10 inch diameter water main shown. The 12 Inca diameter water main must extend to the south property line of the site. As shown in the plans it terminates just south of Lot 10. A fire hydrant will be required near the dead and potion of the water main. A minimum of four fire hydrants are required. One within 150 feet and three within 300 feet of the proposed buildings. Existing hydrants can be counted toward the requirement as long as they meet current code, including 5 Inch storz fittings. Fire flows that exceed 2,500 gpm require a looped main aroundlthrough the proposed buildings or complex of buildings which is not in place at this time and will require water main extensions/replacements. Minimum 4 inch diameter water main extension is required in front of Lots 14. Again, a minimum 15 foot wide easement is required around the water main. Each building (with an individual owner) shall be served by individual domestic water meters directly in front of the lots, Double check valve assembly (DCVA) is required at the domestic water meters since the building height exceeds 30 feet. A pressure reducing valve will be required downstream of each water meter because the water pressure is over 80 psi. The domestic water meters should not be located in the driving surface as shown in the current plans. A 5 foot by 5 foot easement is required for the individual water meters. Water meters shall be located in planting strip or in a location that is not a vehicular traveled surface. The proposed Sunset Blvd NE street section does not include the required 0.5 width for the curb. The required ROW dedication will have to be revised to provide the 0.5 feet wide curb. Staff has also requested one (1) foot clear width back of the sidewalk to be within the ROW. City standards include a maximum slope of 41HA V to a distance of 4 feet back of the sidewalk. Provided an updated street section that shows and labels the required ROW width correctly. Also, minimum 6 inches of crushed rock layer is to be provided below the HMA layer In the pavement. The sewer main should not be located beneath the stonT water facility. Relocate the sewer in the plans or adjust the stormwater facility. The sewer main should not be located in the sidewalk. Please show it within the pavement or paver portion of the alley. A minimum 15 feet wide easement would be required to provide for the sewer main. No buildings ar walls are allowed within to sewer easement. The sewer main should at a minimum extend to the property lines. All lots should be served by individual sewer stubs. The TIR mentioned that Reduced Impervious Surface Credit is provided for Flow Control BMP. The TIR incorrectly refers to the project as a 'Large Lot High Impervious Site' The proposed project is a preliminary plat PUD and proposes individual small lots, so the stonnwater flow control BMP for the individual lots needs to be provided.

The buildings will be required to be located outside the sight triangle lines or clear vision area. Adequate comer curb turning radiuses are to be provided at the internal street and alley intersections to meet fire department requirements. Fire department apparatus access roadways are required to be minimum 20 feel wide fully paved, with 25 feet inside and 45 feet outside turning radius. Adequate turning movements for fire vehicles would not infringe upon pedestrian sidewalks. All internal roads to serve the Planned Urban Development project shall be private alleys located within a tract or tracts. Update the Civil Sheets and the Architectural Sheets to reflect the revised preliminary plat layout. An inverted crown section is to be provided on all private alleys. As a public benefit, staff is recommending that the alley be constructed into a Woonerf (living street), which views the street as a social space, or shared space, rather than just a channel for vehicular mobility. The construction details and specification should be shown in the plans. In general, an alley is constructed of a minimum 4 inches thick HMA over minimum 6 inches of crushed rock for the pavement layer thickness. However, staff is also suggesting the incorporation of pavers into the overall design. A Homeowners Association will be required to be established to ensure maintenance and repair of the private alleys, sidewalks and open space is paid for by the future residents. Update the Draft Legal Documents accordingly. The proposed access location from Sunset Blvd NE (approximately 86 feet north of the south property line to the center of the drive Isle) will require the access to be restricted to a right in right out only driveway with c curbing on Sunset Blvd NE (this is because the access is located In the portion of Sunset Blvd which has the left turn only lane marking). If the applicant wants the City to review full access for the project, then the access location will have to be proposed further north (away from the end of the left turn only lane on Sunset Blvd NE). If the applicant wishes to proceed with the relocated access option, a revised sketch labeling the distances from the nearby street intersection and from the end of the left turn only lane should be submitted for review. If the driveway access Is relocated further to the north, full access to Sunset Blvd NE will require the construction of a two way left turn lane in front of the site. The minimum easement width for water main is 15 feet instead of the 10 feet shown in the current submittal. No buildings or walls are allowed In water easement. In order to meet the fire flow demand, a minimum 12 inch diameter water main is required throughout the site instead of the 10 inch diameter water main shown. The 12 Inch diameter water main must extend to the south property line of the site. As shown in the plans it terminates just south of Lot 10. A fire hydrant will be required near the dead end portion of the water main. A minimum of four fire hydrants are required. One within 150 feet and three within 300 feet of the proposed buildings. Existing hydrants can be counted toward the requirement as long as they meet current code, including 5 inch storz fittings. Fire flows that exceed 2,500 gpm require a looped main around/through the proposed buildings or complex of buildings which Is not In place at this time and will require water main extensionstreplacements. Minimum 4 Inch diameter water main extension is required in front of Lots 14. Again, a minimum 15 foot wide easement Is required around the water main. Each building (with an individual owner) shall be served by Individual domestic water meters directly in front of the lots. Double check valve assembly (DCVA) is required at the domestic water meters since the building height exceeds 30 feet. A pressure reducing valve w€ll be required downstream of each water meter because the water pressure is over 80 psi. The domestic water meters should not be located in the driving surface as shown in the current plans. A 5 foot by 5 That easement is required for the individual water meters. Water meters shall be located in planting strip or in a location that is not a vehicular traveled surface. The proposed Sunset Blvd NE street section does not include the required 0.5 width for the curb. The required ROW dedication will have to be revised to provide the 0.5 feet wide curb. Staff has also requested one (1) foot clear width back of the sidewalk to be within the ROW. City standards include a maximum slope of 4H.1 V to a distance of 4 feet back of the sidewalk. Provided an updated street section that shows and labels the required ROW width correctly, Also, minimum 6 inches of crushed rock layer is to be provided below the HMA layer in the pavement The sewer main should not be located beneath the stormwater facility. Relocate the sewer in the plans or adjust the stormwater facility. The sewer main should not be located in the sidewalk. Please show it within the pavement or paver portion of the alley. A minimum 15 feet wide easement would be required to provide for the sewer main. No buildings or walls are allowed within the sewer easement. The sewer main should at a minimum extend to the property lines. All lots should be served by individual sewer stubs. The TIR mentioned that Reduced Impervious Surface Credit is provided for Flow Control BMP_ The TIR incorrectly refers to tfre project as a "Large tot High Impervious Site." The proposed project is a preliminary plat PUD and proposes Individual small lots, so the stormwater flow control BMP for the individual lots needs to be provided. The City Amendment of the 2009 KCSWDM includes 6 Special Requirements. The Stormwater TIR should mention all the 6 Special requirements. All internal roads, alleys, surface parking for guests shall be located within a tract or tracts. Likewise, the retaining walls being constructed to support the private road and utilities should also be included in the tract(s) controlled and maintained by the Homeowners Association and not the individual owners of the lots.

The vacant 0.9 acre site is located within the Residential Multi -Family (RMF) zoning classification and the Residential High Density (RHD) land use designation. The development would be comprised of 15 multi -family residential structures with attached garages resulting in a net density of 17.5 du/ac. The subject site is consists of three separate adjacent tax parcels located at 701-707 Sunset Blvd NE at the intersection of NE 7th St and Sunset Blvd N. The plat is proposed to be subdivided into 15 lots and 1 tract. The applicant would dedicate 1,943 sf of land for public right- of-way along Sunset Blvd N. The proposed lots would range in size from 737 sf to 909 sf with an average lot size of 816 sf. Access to the undeveloped site is proposed via single road at the midpoint of the development from Sunset Blvd NE. The PPUD would be used to vary development standards (such as lot size, building setbacks, impervious surface area, and building coverage), street standards, parking requirements, and refuse and recycling. The applicant has proposed enhanced open space, superior pedestrian and vehicular circulation, pedestrian amenities, guest parking, and landscaping as a public benefit. The eastern two-thirds of the site are relatively level. The western third of the site consists of a moderate to steep slope which descends to the west at grades of 50 to 60 percent and represent an elevation change of 15 to 20 feet. There are moderate to steep slopes, high erosion hazards, and high landslide hazards mapped in the area. The applicant has proposed to retain five (5) of the 17 significant trees onsite.

Planning Review Comments Contact: Clark Close 1425-436-72891cclose@rentonwa.gov The following information will need to be submitted before March 13, 2017 so that we may continue the review of the above subject application: Adequate sight distance should be provided at the street intersections. The buildings will be required to be located outside the sight triangle lines or clear vision area. Adequate comer curb turning radiuses are to be provided at the internal street and alley intersections to meet fire department requirements. Fire department apparatus access roadways are required to be minimum 20 feet wide fully paved, with 25 feet inside and 45 feet outside turning radius. Adequate turning movements for fire vehicles would not infringe upon pedestrian sidewalks. All internal roads to serve the Planned Urban Development project shall be private alleys located within a tract or tracts. Update the Civil Sheets and the Architectural Sheets to reflect the revised preliminary plat layout. An inverted crown section is to be provided on all private alleys. As a public benefit, staff is recommending that the alley be constructed into a Woonert (living street), which views the street as a social space, or shared space, rather than just a channel for vehicular mobility. The construction details and specification should be shown in the plans. In general, an alley is constructed of a minimum 4 inches thick HMA over minimum 6 inches of crushed rock for the pavement layer thickness. However, staff is also suggesting the incorporation of pavers into the overall design. A Homeowners Association will be required to be established to ensure maintenance and repair of the private alleys, sidewalks and open space is paid for by the future residents. Update the Draft Legal Documents accordingly. The proposed access location from Sunset Blvd NE (approximately 86 feet north of the south property line to the center of the drive isle) will require the access to be restricted to a right in right out only driveway with c curbing on Sunset Blvd NE (this is because the access is located in the portion of Sunset Blvd which has the left turn only lane marking). If the applicant wants the City to review full access for the project, then the access location will have to be proposed further north (away from the end of the left turn only lane on Sunset Blvd NE). If the applicant wishes to proceed with the relocated access option, a revised sketch labeling the distances from the nearby street intersection and from the end of the left turn only lane should be submitted for review. If the driveway access is relocated further to the north, full access to Sunset Blvd NE will require the construction of a two way left turn lane in front of the site. The minimum easement width for water main is 15 feet instead of the 10 feet shown in the current submittal. No buildings or walls are allowed in water easement. In order to meet the fire flow demand, a minimum 12 inch diameter water main is required throughout the site instead of the 10 inch diameter water main shown. The 12 inch diameter water main must extend to the south property line of the site. As shown in the plans it terminates just south of Lot 10. A fire hydrant will be required near the dead end portion of the water main. A minimum of four fire hydrants are required. One within 150 feet and three within 300 feet of the proposed buildings. Existing hydrants can be counted toward the requirement as long as they meet current code, including 5 inch storz fittings. Fire flows that exceed 2,500 gpm require a looped main around/through the proposed buildings or complex of buildings which is not in place at this time and will require water main extensions/replacements. Minimum 4 inch diameter water main extension is required in front of Lots 1 4. Again, a minimum 15 foot wide easement is required around the water main. Each building (with an individual owner) shall be served by individual domestic water meters directly in front of the lots. Double check valve assembly (DCVA) is required at the domestic water meters since the building height exceeds 30 feet. A pressure reducing valve will be required downstream of each water meter because the water pressure is over 80 psi. The domestic water meters should not be located in the driving surface as shown in the current plans. A 5 foot by 5 foot easement is required for the individual water meters. Water meters shall be located in planting strip or in a location that is not a vehicular traveled surface. The proposed Sunset Blvd NE street section does not include the required 0.5 width for the curb. The required ROW dedication will have to be revised to provide the 0.5 feet wide curb. Staff has also requested one (1) foot clear width back of the sidewalk to be within the ROW. City standards include a maximum slope of 4H: IV to a distance of 4 feet back of the sidewalk. Provided an updated street section that shows and labels the required ROW width correctly. Also, minimum 6 inches of crushed rock layer is to be provided below the HMA layer in the pavement. The sewer main should not be located beneath the stormwater facility. Relocate the sewer in the plans or adjust the stormwater facility. The sewer main should not be located in the sidewalk. Please show it within the pavement or paver portion of the alley. A minimum 15 feet wide easement would be required to provide for the sewer main. No buildings or walls are allowed within the sewer easement. The sewer main should at a minimum extend to the property lines. All lots should be served by individual sewer stubs. The TIR mentioned that Reduced Impervious Surface Credit is provided for Flow Control BMP. The TIR incorrectly refers to the project as a "Large Lot High Impervious Site." The proposed project is a preliminary plat PUD and proposes individual small lots, so the stormwater flow control BMP for the individual lots needs to be provided.

Likewise, the retaining walls being constructed to support the private road and utilities should also be included in the tract(s) controlled and maintained by the Homeowners Association and not the individual owners of the lots. A geotechnical report based on the detailed requirements of RMC 4 8 120D.7 Table 18 is required. Including, but not limited to, information regarding water table and soil permeability with recommendations of appropriate flow control BMP options with typical designs for the site from the geotechnical engineer, slope stability analysis, soil suitablelunsuitable for infiltration, recommendations regarding the construction in protected and regulated slopes given a major portion of the site is located in a high erosion hazard area and the entire site is located in the high landslide area. In any residential district, the maximum height of any fence, hedge or retaining wall shall be seventy two inches (72"). Terracing is the act of forming hillside into a number of level flat areas (terraces) between retaining walls, which is often used when the maximum height of a single retaining wall is insufficient. Please refer to retaining wall standards (RMC 4 4 040) for additional information. For example there shall be a minimum three foot (3) landscaped setback at the base of retaining walls abutting public rights of way. A modification request under the Planned Urban Development application would be required to deviate from Renton Municipal Code. In approving a planned urban development, the City may modify any of the standards of chapter 4 2 RMC, RMC 4 3 100, chapter 4 4 RMC, RMC 4 6 060 and chapter 4 7 RMC, except as listed in subsection B3 of RMC 4 9 150. All modifications shall be considered simultaneously as part of the planned urban development. No buildings or walls should encroach into the existing public utilities (water and sewer) easement located on the west side of the parcels (KC Recording Nos, 7709060790, 7709060791 and 7709060794). A strong component of the public benefit will include a great lighting plan and signage package for the internal private alley (Woonerf). Please provide. Private alleys do not have to be excluded from density. Revise and resubmit the density worksheet based on the changes to the street classification and the amount of right of way required along Sunset Blvd NE.

The buildings will be required to be located outside the sight • Adequate corner curb turning radius are to be provided at the internal street intersections to meet fire department requirements. • If the PUD code allows private alley to serve the development, then an inverted crown section is to be provided. Minimum 4 inches thick HMA over minimum 6 inches of crushed rock is required for the pavement layer thickness. This is to be shown in the plans. A Homeowners Association will be required to be established and the home owners will be required to provide yearly funds that will be used for the maintenance and repair of the private access and the sidewalks. • The proposed access location from Sunset Blvd NE will require the access to be restricted to a right in right out only driveway with c curbing on Sunset Blvd NE (this is because the access is located in the portion of Sunset Blvd which has the left turn only lane marking. If the applicant wants the City to review full access for the project, then the access location will have to be proposed further north (away from the end of the leaf turn only lane). It the applicant wishes to proceed with the relocated access option, a revised sketch labeling the distances from the nearby street intersection and from the end of the left turn only lane should be submitted for review. The relocated full access will also require the construction of a two way left turn lane in front of the site. • The minimum easement width for water main is 15 feet instead of the 10 feet shown in the current submittal. (Informational comment No buildings or walls are allowed in water easement). The 15 feet wide easement may impact the proposed location of some buildings (i.e. building in Lot 4). Correct and show in the plan. A minimum 12 inch diameter water main is required throughout the site instead of the shown 10 inch diameter water main (this is to meet the fire flow demand). Show in the plan.

Show in the plan. Fire hydrant will be required near the dead end portion of the water main. Other fire hydrant requirements shall be as per the fire department requirements. • Minimum 4 inch diameter water main extension is required in front of lots 1 to 4. Minimum 15 feet wide easement is required for the water main. • Each building with individual owner shall be served by individual domestic water meters directly in front of the lots. (Informational comment Double check valve assembly (DCVA) is required at the domestic water meters since the building height exceeds 30 feet. A pressure reducing valve will be required downstream of each water meter because the water pressure is over 80 psi.) The domestic water meters should not be located in the driving surface as shown in the current plans. 5'x5' easement is required for the individual water meters. Water meters shall be located in planting strip or in a location that is not a vehicular travelled surface. • The proposed Sunset Blvd street section does not include the separate 0.5 width for curb separate from the 8 feet wide planter and 8 feet wide sidewalk, the cross section and required ROW dedication will have to be revised to provide the 0.5 feet wide curb. The preapplication memo had also mentioned a 1 feet clear width back of the sidewalk to be within the ROW. Show the section correctly and show and label the required ROW width. Also, minimum 6 inches crushed rock layer is to be provided below the HMA layer in the pavement. (Additional information —City standards include a maximum slope of 4H:1 V to a distance of 4 feet back of the sidewalk). • Sewer — The sewer main should not be located beneath the stormwater facility. Relocate the sewer in the plans, or adjust the stormwater facility. No buildings, walls, etc should encroach on the existing public sewer easement located on the west side of the site. Please show and label the existing easement clearly in the plan. • The sewer main should not be located in the sidewalk, show it within the pavement portion. If the internal access is private, then a minimum 15 feet wide easement should be provided for the sewer main. (Informational comment No buildings or walls are allowed within the sewer easement). • The sewer main should at a minimum extend to the north lot line of lot 11. • All lots should be served by individual sewer stubs. • Stormwater — The TIR mentioned that Reduced Impervious Surface Credit is provided for Flow Control BMP. The TIR incorrectly refers to the project as a large Lot High Impervious Site. This project is a plat PUD and proposes individual small lots, so the stormwater flow control BMP for the individual lots is to be provided. • Stormwater TIR — City Amendment of the 2009 KCSW DM includes 6 Special Requirements. The TIR should mention all the 6 Special requirements. • As mentioned in the preapplication comments, a geotechnical report based on RMC 4 B 120.D.7 containing all information shown in Table 18, separated into sections is required. Information regarding water table and soil permeability with recommendations of appropriate flow control BMP options with typical designs for the site from the geotechnical engineer shall be submitted with the application along with the slope stability analysis. The geotech report should include information if the soil is suitable/unsuitable for infiltration. Since the major portion of the site is located in a high erosion hazard area, the entire site is located in the high landslide area, the site has regulated slopes including protected slopes (between 40% to 90% slopes), sensitive slopes (between 25% to 40% slopes), and slopes lesser than 25%, the geotech engineer's recommendation regarding the construction in above mentioned critical areas should be clearly included in the geotech report with respective construction recommendations as applicable.

The checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. 3. It is our understanding that a 10 year dredging permit was issued and modified for parcel 0518501150 (Cuigini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. As part of the Notice of Application, City staff indicated that the dredging work may inadvertently spill over onto the May Creek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in Lake Washington. Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specifically stated that the dredging a 10,000 square foot area by 2 feet every 3 5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the following: a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented. An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; b. A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown; and c. The location and success of previous mitigation measures for the previously permitted dredging work. 5. Also parcel 3342700009 (3907 Lake Washington Blvd N) currently does not have a dock or any structure that provides moorage. Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of important shallow water habitat for juvenile salmon as the moorage needs can be accommodated by other means (i.e. expansion of existing joint moorage facilities, buoys, etc.). 6. Please provide additional information regarding the necessary navigational depth profile for each parcel. This information should be presented parcel by parcel in a table. 7. Please provide monitoring data from previous dredging work. It is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. 8. One document that was sent via email with the Notice of Application is the Biological Assessment dated August 27, 2012 is for the dredging at the Boathouse parcel (0518501150); the parcel immediately south 3342700005 (3979 Lake Washington Blvd N); and a portion of parcel 3342700007 (3909 Lake Washington Blvd N). It does not cover dredging at the other parcels noted in the master land use application or NOA. Please indicate the control mechanism to avoid any spill over onto the May Creek Delta parcel (APN 0518500000) and why dredging work of parcels 3342700009 (3907 Lake Washington Blvd N) and 3342700011 W05 Lake Washington Blvd N) were included in the proposal. 9. The assessment regarding potential salmon impacts as described in the 2012 Biological Assessment is based on limited information (i.e. Tabor et al 2004). Much more research data and information has been collected since this and should be used in a revised Biological Assessment or another environmental assessment format.

Please provide additional discussion and figures showing where and what mitigation was required and completed from the previous dredging permits. 11. The Sediment Sampling and Analytical Results report. From a quick review, the report is missing Attachments C. and D, most importantly the actual sediment sampling results from Analytical Resources Inc. This information should be included and available for review.

Lake Washington is the second largest natural lake in the State of Washington with 80 miles of shoreline. Lake Washington is a shoreline of Statewide Significance and is classified as a Type-S waterbody. The project area includes five waterfront lots in the Eagle Cove area of Lake Washington at 3905, 3907, 3909 and 3979 Lake Washington Blvd N, Renton, WA 98056 and 4011 Wells Ave N, Renton, WA 98056 (King County Assessor's Parcel Nos. 3342700011, -0009, - 0007, -0005, and 0518501150, "Subject Property"). The subject property is located just south of Barbee Mill townhouse development within the within the NW of Sections 32, Township 24 North, Range 05 East, W.M. King County, Washington and has been dredged for many decades (Exhibits 2). According to the Biological Assessment, dredging of the May Creek Delta and boathouse area has occurred for over 50 years on a 3- to 4-year cycle (Exhibit 12). Most recently, the area was dredged in 1994, 1997, 2001/2002 and 2011 due in part to high sediment loading, lack of large woody debris (LWD), loss of habitat complexity, forest removal, presence of rock quarries, and the expansion of road networks in the lower four (4) miles of May Creek watershed. A portion of the Barbee Boathouse Navigational Dredge area was last dredged in 2011, concurrent with boathouse renovations under U. S. Army Corps of Engineer (USACE) Permit Reference #NWS-2007-1019 (Exhibits 3 and 17). As permitted by USACE, the applicant is proposing to dredge the permitted profile approved by USACE which would need to be amended to conform to the proposed City of Renton Grade and Fill Permit (Exhibit 18), The proposed profile is not anticipated to reach depths that would encounter sediments that are older than dredging work completed in 2011 or in previous dredging events. The applicant is proposing to not dredge to depths that are at or below 10 to 12 feet in elevation. In 2002, the depth at the western edge of the dredge footprint was approximately 15-20 feet deep, well below proposed dredge profile. In 2005, for example, the water depth at the Eagle Roost (also periodically referred to the Osprey Nest) was approximately 10 feet. Per the Sediment Sampling and Analytical Results (Exhibit 9), there has been over 10 feet of depositional infill from ongoing erosional events since 2005 with volumes of material deposited in Lake Washington at the May Creek Delta estimated at 25,000 cubic yards or higher. The Renton Environmental Review Committee (ERC) issued a threshold Determination of Nan -Significance - Mitigated with Mitigation Measures for dredging of May Creek Delta to remove coarse sands (SP — MP) grading to gravels in closer proximity to the mouth of May Creek (Exhibit 4). Sediments distal to May Creek tend to be finer materials and some silt. Within the May Creek delta, larger rocks and gravels tend to predominate. The dredging permitted under LUA05-138, SP, ECF was issued on March 14, 2006 for approximately 55,000 square feet or approximately 3,000 to 4,000 cubic yards of coarse sand and gravel to be dredged every 3 to 4 years for a 10-year period. Subsequently in 2016, the site received a shoreline exemption permit for environmental enhancements and mitigation measures arising from state and federal permitting requirements to improve near -shore shallow water habitat. The approved enhancements included the following: replacement of a solid float with a high light -transmission grated float, extraction of treated and untreated wood piles, replacement of wood piles with four galvanized pipe piles, removal of several large angular rocks at base of basaltic columnar rockery, and placement of approximately 20 cubic yards of rounded river rock at the rockery. These environmental enhancements were in response to approval of the 10-year Shoreline Substantial Development Permit for dredging the mouth of May Creek (Exhibit 5). North of the former Barbee Mill facility (approximately 2,000 ft), is Quendall Terminals (a superfund site). Primary contaminants at this site are creosote residues (PAH compounds) and petroleum hydrocarbons. Barbee Lumber Mill operations occurred north of the May Creek Delta, and south of Quendall Terminals. Lumber mill operations were essentially shut down in 1999. The boathouse area has been periodically dredged since the ERC Report City of Renton Department of Community & imic Development vironmental Review Committee Report SEDIMENT REPOSITION MITIGATION LUA16-000977, ECF, SM Report of March 6, 2017 Page 3 of S early 1950's to maintain navigational access to the boathouse. There is no record of spills or other discharges impacting sediments in the proposed dredge area although low levels of petroleum hydrocarbons were detected during sampling and chemical analysis in 2008. Sediments in the proposed dredge area arise principally from deposition during severe storm events (high energy) when sediment loadings carried from the May Valley Drainage Basin are substantial. Following notification of application, the Muckleshoot Indian Tribe Fisheries Division provided several questions and comments regarding the application (Exhibit 14). The project was placed on -hold (Exhibit 15) and the applicant was able to respond to the on -hold letter and the initial comments and questions that were raised during the public comment period (Exhibit 16). The properties have a Comprehensive Plan land use designation of Residential High Density (RHD) and Residential Medium Density (RMD) and a zoning designation of Residential -10 (R-10) and Residential-6 (R-6) and are located along the waterfront of Lake Washington. The applicant is proposing to dredge depositional sediments that have infilled the navigational access to the boathouse. The Barbee Company has secured all permits to dredge the area from the USACE and is currently updating permits from state and local jurisdictions. The land surrounding the site is zoned R-10 to the north, R-6 to the east and south, and Lake Washington is located to the west.

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 applicant submitted a Sediment Sampling and Analytical Results Report (revised date December 12, 2016; Exhibit 9) along with Geotechnical Design Parameters for Anchor Piles prepared by Geotech Consultants, Inc. (dated January 10, 2010; Exhibit 10) and Geotechnical Observations during Pile Installation prepared by Geotech Consultants, Inc. (dated August 9, 2011; Exhibit 11). This full report provided results of sediment sampling and chemical testing of sediments (mostly fine to medium sand of recent depositional origin) in conjunction with proposed maintenance dredging, The sampling and analysis program was conducted to chemical collect data regarding the levels of contamination that may or may not be present within sediments of the permitted dredge area and to assess the suitability of dredged materials for disposal. The Sediment Report found that the detected chemical contamination in the permitted dredge area to be very limited or below Dredge Material Management Program (DMMP) fresh water and marine screening levels. The results of the report indicated some motor oil range petroleum hydrocarbon detected at 39 mg/kg (dry basis), diesel range petroleum product detected in the composite sample at 8.3 mg/kg (dry basis), and traces of Polynuclear Aromatic Hydrocarbons (PAHs). For example, benzo(a)pyrene was detected at 24 ug/Kg (dry basis). The Sediment Sampling and Analytical Results Report concludes that based on Analytical Testing Data and Screening Level comparisons, sediments proposed to be dredged at the project site were found to be suitable for open -water disposal. The applicant stated that the purpose of the proposed dredging project is to dredge the least amount of depositional material possible to maintain navigational and recreational access, not to restore historical lakebed elevations in Lake Washington (Exhibit 6). While as the same time, demonstrate that the proposed modifications would result in no net loss, meaning the applicant must demonstrate that the modifications, combined with any mitigation efforts, would result in equivalent or better protection of shoreline functions. Based on current bathymetry, the applicant is proposing to dredge approximately 2,500 to 4,000 cubic yards of sediment during each dredging event (Exhibit 7). The applicant has requested a 10-year permit to conduct Sediment Deposition Mitigation dredging. The first phase would be completed in the summer of 2017 and would include approximately 2,500 to 2,700 cubic yard of dredged material, based on 2016 hydrographic ERC Report City of Renton Department of Community & Economic Development environmental Review Committee Report SEDIMENT DEPOSITION MITIGATION LUA16-000977, ECF, SM Report of March 6, 2017 Page 5 of 8 data, and environmental enhancement work as dredging mitigation. The second phase of sediment mitigation dredging is anticipated to begin within the next 5 years of the requested 10-year permit. Because of weather, particularly severe storm events, and unpredictable deposition patterns, there is a potential for a third dredging event. A ten-year permit was requested by the applicant due to anticipated sediment deposition from May Creek Valley as a result of upstream erosion caused by severe storm event (high energy). At the completion of the amended USACE permit, which runs until February 5, 2026, a hydrographic survey would be conducted by the applicant for post -dredge survey results (Exhibit 3). According the Sediment Sampling and Analytical Results Report, the parcels that have received the most depositional infill sediments of fine to medium sands with some gravel (identified as well draining fill material) in recent years were 3979 Lake Washington Blvd N (Lot A) and a major portion of3909 Lake Washington Blvd N (Lot B). Finer sediments were identified as unsuitable for shallow water fish habitat enhancement along the rockery to the immediate south. 3907 Lake Washington Blvd N (Lot C) and 3905 Lake Washington Blvd N (Lot D) were not impacted to an extent that dredging would be required in 2017. Likewise, it is anticipated that 4011 Wells Ave N (boathouse property) would also not require a lot of sediment removal in the near term. The applicant has indicated that the sediment deposition from the May Valley is a dynamic process and estimating future sediment loadings by parcel is not possible given the unknowns of weather, sediment deposition rates, deposition directions and locations, as well as estimating the effectiveness of proposed measures to mitigate deposition. The focus of the proposed dredging project is to mitigate sediment deposition in 2017 and restore navigational access in the northern portion of the subject property. The applicant is proposing to dredge from deeper water to more shallow water to provide access for barge mounted equipment. At no time would dredging occur from the land with the potential for "spill over" to the May Creek Delta parcel. The applicant is proposing to leave an approximately 4 to 6 feet wide shelf from the northern property line of Lot A which would not be dredged. This area is being set aside for environmental enhancement/mitigation to provide a base to install root wads (Exhibit 8). Environmental Enhancement and mitigation measures for the proposed project, arise from existing state and federal permitting requirements to improve near -shore shallow water habitat work through the various shoreline permits, including USACE Permit Reference #NWS-2007-1019 (Exhibit 3), Lake Washington/May Creek Dredging DNS-M, LUA05-138, SP, ECF (Exhibit 4) and Barbee Maintenance Dredging Mitigation Shoreline Exemption, LUA16-000388, SME (Exhibit 5). A few of the mitigation measures included, but were not limited to, the following: ■ Placement of 20 cubic yards of rounded river rock ("fish rock") along the rockery as well as several yards of fish rock adjacent to the boat ramp on Lot A to enhance the near shore shallow water habitat with more fish friendly materials; • Replacement of a 150-foot long solid wood float with a single 40-foot long grated float that maximizes light transmission to the shallow water habitat; ■ Replacement of three (3) failing creosote and rotted untreated wood piles securing the old float with two 10" galvanized steel pipe piles; and ■ Removal of wood and metal debris and rotting wood/leaf debris that depletes dissolved oxygen in the water column. Shoreline enhancement for near shore planting was completed in previous years, prior to 2011. According to the Lake Study (Exhibit 13), the proposed project would involve amending the current Corps programmatic permit to allow dredging of up to an additional 4,000 cubic yards of sediment in an area located adjacent to the existing permitted dredge prism (Exhibit 6). Dredging to achieve the desired navigational depth profile would deepen the expanded dredge prism by approximately 10 feet (Exhibit 7). ERC Report City of Renton Department of Community & tconamic Development SEDIMENT DEPOSITION MITIGATION Report of March 6, 2017 Environmental Review Committee Report LUA16-000977, ECF, SM Page 6 of 8 This expansion of the dredge prism would align it with the existing property and inner harbor lines, facilitate safe navigational access to the boathouse, and promote future recreational uses. The applicant is proposing three potential options for handling the dredged material: Option 1: Off-loading at the boat ramp on Lot A and trucking the materials off -site. Sediments would be placed on a flat barge and allowed to "dry' to the extent that water would not leak during transit. If "free" water is observed, then trucks would be lined to eliminate drippage. This option would require haul routes through Barbee Mill which would disturb residents more than other options. Dry sediments would be hauled off -site for sale or other beneficial use. Option 2: Off-loading the barge at a site on Lake Washington or Lake Union (TBD). Clean sediments would be dredged to a barge and off-loaded to another site on Lake Washington. It may be beneficial for other receiving site to obtain clean sands. Option 3: Open water, ocean disposal. Ocean disposal is an option for receiving clean sediments from the project site at the Puget Sound Open Disposal site. Additional sediment sampling may be necessary to meet USACE requirements for ocean disposal. If either Option 1 or Option 2 is implemented for handling sediments, a detailed Traffic Control Plan would need to be submitted and approved by the City of Renton prior to the start of construction. Construction hours would be in accordance with City Standards. The 2016 Lake Study included seven environmental protection and enhancement measures for the sediment deposition mitigation project. Staff recommends a SEPA mitigation measure that the applicant shall comply with the environmental protection and enhancement measures found in the Lake Study prepared by Meridian Environmental, Inc. (dated December 23, 2016) or updated report submitted at a later date. Mitigation Measures: The Sediment Deposition Mitigation project shall be required to comply with the environmental protection and enhancement measures found in the Lake Study prepared by Meridian Environmental, Inc. (dated December 23, 2016) or updated report submitted at a later date. Nexus: State Environmental Policy Act (SERA) Environmental Review, RMC 4-3-050 Critical Areas Regulations, RMC4-3-090 Shoreline Master Program Regulations, and RMC 4-4-060 Grading, Excavation and Mining Regulations. 2. Air Impacts: It is anticipated that some temporary adverse air quality impacts associated with the dredging of the subject property and relocation of the dredge spoils would occur. Diesel exhaust emissions from the heavy dredging equipment and large vehicles needed to transport the material will be a source of air pollution. Maintenance of the equipment to meet State and Federal air quality requirements would serve to mitigate the potential adverse impacts. No further site specific mitigation for the identified impacts from typical vehicle and construction exhaust is required. Mitigation Measures: No further mitigation recommended. Nexus: NIA 3. Water a. Surface Water Impacts: The project site is located and composed of aquatic lands in Lake Washington. The proposed dredging near May Creek in Lake Washington and the installation of LWD could have some short-term adverse impacts. The dredging itself would stir -up some sediment in the water but the sediments should settle out of the water fairly quickly after the dredging has been completed. According to the applicant, dredge work would require approximately 80 hours over a 10 day period. ERC Report City of Renton Department of Community & Economic Development Environmental Review Committee Report SEDIMENT DEPOSITION MITIGATION LUA16-000977, ECF, SM Report of March 6, 2017 Page 7 of 8 The applicant is proposing minimization techniques, such as lining the perimeter of the barge with hay bales wrapped with filter fabric to prevent dredge material from entering Lake Washington, where it could cause turbidity. Dredging would only be conducted during National Marine Fisheries Service (NMFS) approved July 16-September 15 work window by avoiding work during the rainy season. In addition, the Lake Study is also proposing to avoid dredging along shoreline slopes and shallow water habitat along the shoreline north of the dredging zone to protect near -shore habitat that may be used by rearing Chinook salmon and enhance the north end of the project boundary through the placement of LWD (approximately five to ten rootwads). According to the applicant, the LWD would serve to improve aquatic habitat, help stabilize the shoreline, and facilitate sediment deposition to reduce the need for future maintenance dredging in the future. The applicant submitted a Lake Study prepared by Meridian Environmental, Inc. (dated December 23, 2016; Exhibit 13) which concludes that the proposed project would unlikely have an adverse effect on adult salmon and steelhead spawning habitat, as no dredging would take place in May Creek. The proposed project may affect juvenile salmon and steelhead by causing physical changes to their early rearing habitat in Lake Washington. Limiting the in -water work to the NMFS work window would minimize the potential to adversely affect juvenile Chinook, coho and steelhead, as the vast majority of juveniles in Lake Washington are expected to migrate prior to July. The dredging work proposed by the applicant is also subject to the U, S. Army Corps of Engineer (USACE) Permit Reference #NWS-2007-1019 conditions of approval (Exhibit3) and the Barbee Maintenance Dredging Mitigation Shoreline Exemption permit condition of approval (Exhibit 5). The applicant submitted a Biological Assessment prepared by Meridian Environmental, Inc. (dated August 27, 2012; Exhibit 12) which included nine conservation measures that the applicant would implement to avoid or minimize take of listed species and avoid or reduce impact to their habitat. Staff recommends as a SEPA mitigation measure that dredge project be required to comply with the conservation measures found in the Biological Assessment prepared by Meridian Environmental, Inc. (dated August 27, 2012). Mitigation Measures: The Sediment Deposition Mitigation project shall be required to comply with the conservation measures found in the Biological Assessment prepared by Meridian Environmental, Inc. (dated August 27, 2012). Nexus: State Environmental Policy Act (SEPA) Environmental Review, RMC 4-3-050 Critical Areas Regulations, RMC 4-3-090 Shoreline Master Program Regulations 4. Environmental Health a. Noise Impacts: Noise impacts would primarily result from heavy equipment used during dredging and environmental enhancement construction work. The equipment noise would be regulated through the City's adopted noise level regulations per Chapter 8-7, RMC. The City's noise regulations limit haul hours between 8:30 am to 3:30 pm, Monday through Friday unless otherwise approved by the Development Services Division. Permitted work hours in or near residential areas are restricted to the hours between seven o'clock (7:00) a.m. and eight o'clock (8:00) p.m. Monday through Friday. Work on Saturdays is restricted to the hours between nine o'clock (9:00) a.m. and eight o'clock (8:00) p.m. No work is permitted on Sundays. Noise impacts anticipated are anticipated to be short-term impacts that would be commonly associated with dredging activities. Generally, noise impacts would come from the operation of the heavy construction equipment (frontend loaders, etc) that would generate expected noise levels of up 80 or 90 decibels (Exhibit 19). The applicant indicates that all the construction noise impacts are anticipated to occur during daylight hours. No unusual noise impacts are proposed, which would require further levels of mitigation. Mitigation Measures: No further mitigation recommended.

The permit authorizes the dredging of up to 4,000 cubic yards of sediment over a 10,000-square-foot area; renovation of a boathouse, placement of spawning gravel, and the replacement of floats in Lake Washington at Renton, Washington, The original time limit for completing the authorized dredging is scheduled to expire on January 8, 2019. You have requested a modification of the permit to dredge up to an additional 2,700 cubic yards over an additional 14,000-square-foot area; replace an existing solid wood float and three creosote - treated piles with a grated float and two galvanized steel piles; and replace two 3-pile dolphins with two galvanized steel piles. Your request for a permit modification and time extension is approved. Enclosed are the approved modified plans dated August 21, 2012, which supersede plans authorized by the Secretary of the Army on January 8, 2009. The new time limit for comp.teting the authorized dredging ends 10 years from the date of this approval letter, The new time limit for completing the other authorized work ends 3 years from the date of this approval letter_ We have modified three of the original conditions as a result of our recent pen -nit review as follows: d. You must implement and abide by the Endangered Species Act (ESA) requirements and/or agreements set forth in the Cugini Property Boathouse Expansion of'the Existing Lake Washington Dredge Prism Biological &sessment dated August 27, 2012, and the addendum dated April 3, 2014, in their entirety. The U.S. Fish and Wildlife Service (USFWS) concurred with a finding of "may affect, not likely to adversely affect" based on this document on May 15, 2014 (USFWS Reference Number 13410-2008-I-0149). The USFWS will be informed of this permit issuance. Failure to comply with the commitments made in this document EXHIBIT 3 -2- constitutes non-compliance with the ESA and your U.S. Army Corps of Engineers permit. The USFWS is the appropriate authority to determine compliance with ESA. e. This U.S. Army Corps of Engineers (Corps) permit does not authorize you to take a threatened or endangered species, in particular the Puget Sound Chinook and steelhead. In order to legally take a listed species, you must have a separate authorization under the Endangered Species Act (ESA) (e.g., an ESA Section 10 permit, or ESA Section 7 consultation Biological Opinion (BO) with non -discretionary "incidental take" provisions with which you must comply). The enclosed BO prepared by the National Marine Fisheries Service (NMFS) dated October 6, 2014, contains mandatory terms and conditions to implement the reasonable and prudent measures that are associated with the specified "incidental take" in the BO (NMFS Reference Number WCR-2014-770), Your authorization under this Corps permit is conditional upon your compliance with all of the mandatory terms and conditions associated with incidental take of the enclosed BO. These teems and conditions are incorporated by reference in this permit. Failure to comply with the terms and conditions associated with incidental take of the BO, where a take of the listed species occurs, would constitute an unauthorized take, and it would also constitute non-compliance with your Corps permit. The NMFS is the appropriate authority to determine compliance with the terms and conditions of its BO and with the ESA, f. In order to meet the requirements of the Endangered Species Act you may conduct the authorized activities from July 16 through September 15 in any year this permit is valid. You shall not conduct work authorized by this permit from September 16 through July 15 in any year this permit is valid. We have added the following three permit conditions as a result of our recent permit review: m. Any deviations #tom the authorized dredging footprint or depths must be reported to the Regulatory Branch Project Manager within 24 hours of discovery. n. Plotted results of the past -dredge bathyrnetric survey shall be submitted to the U.S. Army Corps of Engineers, Seattle District, Dredged Material Management Office and Regulatory Branch Project Manager in PDF format within 30 days of completion of dredging. Results must clearly display the post -dredge sediment surface in relation to The permitted dredge boundary and depth, as well as the location of project features such as docks, wharfs and other landmarks. The vertical datum must be clearly indicated. Full bathymetric survey data must be submitted upon request. o. At least four months prior to each maintenance dredging activity, the permittee must contact the U.S. Army Corps of Engineers, Dredged Material Management Office to determine whether additional sediment characterization is required. if additional characterization is required, no dredging will be allowed until the sediment surface that will be left after dredging has been determined to meet the Dredged Material Management Program's anti -degradation guidelines. -3- Please be reminded that Special Conditions "d" and "e" of your permit require that you impLement and abide by the ESA requirements and/or agreements set forth in the Biological Evaluation and/or the BO for this project. In particular, note that these documents require that you replace a solid float and creosote -treated piling with a grated float and steel piling; and place 20 cubic yards of gravel.

Box 359 Renton, WA 98057 APPLICANT: Michael Lloyd 38210 SE 92nd St Snoqualmie, WA 98065 PROJECT LOCATION: 3909 LAKE WASHINGTON BLVD N PROJECT DESCRIPTION: The proposed work consists of environmental enhancements and mitigation measures, arising from state and federal permitting requirements, to improve near -shore shallow water habitat (see project plan). These environmental enhancements include, replacement of a solid float with a high light -transmission grated float, extraction of treated and untreated wood piles, replacement of wood piles with four galvanized pipe piles, removal of several large angular rocks at base of basaltic columnar rockery, and placement of approximately 20 CY of rounded river rock (aka, "fish rock") at the rockery. These environmental enhancements are in response to approval of a ten year Shoreline Substantial Development Permit (LUA05-138) for dredging the mouth of May Creek where sediments collect to prevent flooding of the Barbee Mill property and to maintain navigational depths to an existing boat house. These mitigation measures were required as a part of permit approval, and are approved by USAGE (NWS-2007-10-19). The environmental enhancement work is anticipated to be completed during the approved in -water work window in accordance with HPA requirements. The anticipated HPA in -water work window is July, 16 through September, 15 of this year. The applicant is proposing to replace a solid wood float, approximately 25' immediately south of the boathouse. The solid float is 32' long and has an area of 256 sf. A new float that is 24' long and has a surface area of 192 sf will be installed. The new float is 25% smaller. The entire surface area of the float will be grated with high light -transmission grating (>63% light transmission) to substantially improve light transmission to near -shore, shallow water habitat. Three treated piles will be extracted and replaced with EXHIBIT 5 Page 1 of 4 Clty of Renton Deportment of Community & Eco __ is Development Certiftcare of Exemptio_ ,_ om Shoreline Substantial Development Barbee Maintenance Dredging Mitigation Shoreline Exemption LLlA16-000388, SME two smaller galvanized pipe piles to eliminate creosote treated piles. Approximately ten treated piles at the replacement float, mentioned above, will be extracted in accordance with Washington Department of Fish and Wildlife (WDFW) requirements and procedures. Additionally, two dolphins, consisting of three piles each, will also be extracted. Because there may be "stubbed" piles, below the water line, the number of piles is stated as approximate. Extracted piles will be cut into small lengths for disposal at an approved landfill. At no time will any treated wood piling be reused for any purpose. Four pipe piles will be installed. As mentioned above, the three piles at the float will be replaced with two 10" galvanized pile piles to secure the new grated float. Two 12" galvanized pipe piles will be installed to replace the two dolphins identified immediately above. The applicant is proposing to remove several large angular basaltic rocks in the water at the base of the rockery approximately 75' south of the boathouse These rocks will be removed from the water and taken off -site. Approximately 20 CY of approved fish rock will be placed at the base of the rockery and at area immediacy south of the boathouse and adjacent to the existing boat ramp. Of this quantity about 2 or 3 yards will be placed near the boat ramp, and the remainder will be placed at the rockery. SEC-TWN-R: N W32-24-5 LEGAL.

Four pipe piles will be installed. As mentioned above, the three piles at the float will be replaced with two 10" galvanized pile piles to secure the new grated float. Two 12" galvanized pipe piles will be installed to replace the two dolphins identified immediately above. Angular Rock Removal. There are several large angular basaltic rocks in the water at the base of the rockery approximately 75' south of the boathouse. These rocks will be removed from the water and taken offsite. Lloyd & Associates, Inc. of Renton shoreline Exempt—TI Placement of "Fish Rock". ApproximateIy 20 CY of approved fish rock will be placed at the base of the rockery and at area immediacy south of the boathouse and adjacent to the existing boat ramp. Of this quantity about 2 or 3 yards will be placed near the boat ramp, and the remainder will be placed at the rockery. Basis for the Exemption: Completion of this project will improve shallow -water fish habitat. Anticipated dates of work: July -September 2016 Environmental enhancement work is anticipated to be completed during the approved in -water work window in accord with Hydraulic Project Approval (HPA) requirements. Anticipated HPA in -water work window is July] 6 — September 15. Other permits required for proposed project; USACE permit (NWS-2007-10 19) Department of Ecology approvals (Shorelines and Water Quality Certification) Hydraulic Project Approval (WDFW — not yet obtained). Current and proposed use of the site: Currently the site is entirely aquatic lands owned by project proponent. The work site is adjacent to the shoreline and used for navigational access to the boathouse and related recreational uses on lake Washington. There are no proposed changes to site use. Special site features The project site is unique waterfront on Lake Washington. As stated above, the project proponent owns aquatic lands of the water front for four single family homes. There is a boathouse at the north end and a shared -use dock at the south end. The site is also near May Creek. Soil type and drainage conditions: Existing sediments at the project site at the north are principally sands and gravels (with rounded rock up to 8" in diameter) arising from May Creek lacustrine deposition. The sands and gravels grade to finer materials (fine sands and silt) at the south end as one moves further away from sands and gravels deposited by May Creek at the north end of the site (deposition occurs principally during severe storm events). When dredged, the sediments at the north end are known to be well draining sands and gravels with occasional rounded rock. Estimated Construction and Fair Market Value Costs. Construction costs are estimated to be approximately $65,000. The fair market value is harder to estimate, but permitting costs, delays, and transactional and administrative costs, if included in fair market value, bump estimates substantially higher than the construction costs. There is also the difficulty of estimating the value to fishes and wildlife of enhanced shallow -water habitat. Fair Market Value? Just a guess at $300,000. Estimated Quantities and types of materials: Approximately 20 CY of rounded river rock (approved previously by WDFW) will be placed in the water at the rockery, as discussed above. Lloyd & Associates, Inc. t City of Renton — Shoreline Exempti01L request Tree Removal: No trees will be removed. Distance from Ordinary High Water Line: All proposed environmental enhancements at the project site will occur in -water below the ordinary High Water Line (OHWL = 21.8' feet, MSL, USACE datum). Nature of the Existing Shoreline: The existing shoreline is almost entirely a bulkhead composed of basaltic rock. A portion of this project is directed at removal angular rock at the base of the bulkhead and softening the shoreline along the base of the rockery with rounded fish rock. Height Restrictions: No structures are proposed in this environmental enhancement project. Lloyd & Associates, Inc.

This work was authorized by your acceptance of our proposal, P-7895 dated December 2, 2009. Based on our discussions with you, the existing boathouse, which is supported on driven timber piles, will be replaced with a floating boathouse. The existing boathouse and its supporting piles will be entirely removed as a part of this work. The new boathouse will be approximately the same size, and will be close to the existing location, possibly a few feet further toward the west. Anchor piles consisting of driven steel pipes will be installed to laterally restrain the boathouse against wind and impact loads. Collars around the piles will allow the boathouse to rise and fall with the approximate 2-foot seasonal fluctuation in the level of Lake Washington. Excavation of the lake bottom will likely occur at the eastern, shore side of the boathouse, where the water depth is only a few feet. SITE CONDITIONS SURFACE The Vicinity Map, Plate 1, illustrates the general location of the site. The existing boathouse is located on the eastern shore of Lake Washington, just north of the existing residence having an address of 4011 Wells Avenue North. This metal structure is supported over Lake Washington on timber piles. A wood dock also supported on driven timber piles extends over the shallower water along the north side of the boathouse. Neither the boathouse or the dock move with the water level in the lake. To the north of the boathouse is the old Barbee Mill property, which is being redeveloped with detached single-family homes. The storm detention pond for this neighboring development is situated on land immediately north of the dock. At the time of our field explorations on January 7, 2010, the level of Lake Washington was low. Based on review of the Corps of Engineers' website (www.nwd-w_c.usace.army.mil) the elevation of the water surface in Lake Washington typically varies between a maximum of 22 feet in mid - EXHIBIT 10 OEOTECH CONSULTANTS, INC_ Lloyd & Associates, Inc. 38210 Southeast 92nd Street Snoqualmie, Washington 98065 Attention: R.

Six piles were located on each of the north and south sides of the new boathouse. A minimum of 15-foot embedment into dense soils was required by the structural engineer to achieve sufficient vertical capacity and lateral bending resistance. Representatives from our firm observed the installation of the piles on July 25 through 27, 2011, Pacific Piling utilized a large vibratory hammer to install the H-piles vertically. As required by the plan, galvanized W1474 beams were installed for the boathouse. Through observation of the penetration rate, we were able to verify that all piles were installed to at least 15 feet of embedment into the dense soils. The pile lengths necessary to reach sufficient embedment increased from east to west, as was expected. Based on our observations, it is our professional opinion that the piles were driven an acceptable manner and reached sufficient embedment into dense soils to support the design loading.

We have several questions and initial comments as noted below: 1. What is the total duration of this dredging proposal? The NOA describes an every 3-5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year; however, there is no information for phase 2 and how the 10 year request was derived. 2. More information is needed regarding the full extent of dredging. The Notice describes 5 specific parcels covering 91,000 square feet. However, the checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and need include the extent of area proposed needs to be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings that are sufficiently scaled and labeled. The drawings submitted with the application lack sufficient detail to make these determinations. 3. It is our understanding that a 10-year dredging permit was issued and modified for parcel 0518501150 (Cuigini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. Also, please explain why parcel 0518500000, which includes the May Creek delta, is part of this proposal. Previous environmental materials, including the Biological Asssessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specfically stated that the dredging a 10,000 square foot area by 2 feet every 3-5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the following: Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented. An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown; The location and success of previous mitigation measures for the previously permitted dredging work; 1 EXHIBIT 14 5. Also parcel 3342700009 (3907 Lake Wasington Boulevard) currently does not have a dock or any structure that provides moorage. Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of imporant shallow water habitat for juvenile salmon as the moorage needs can be accommodated by other means (i.e. expansion of existing joint moorage facilities, buoys, etc.) 6. More information is also needed regarding the necessary navigational depth profile that all of these parcels need. Again this information should be presented individually by the parcels listed in the NOA. 7. Monitoring data from previous dredging work should be provided, too, as it is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. 8. The application references the Sediment Sampling and Analytical Results prepared by Lloyd and Associates (revised December 12, 2016). This document was not included in the materials sent via email. We would appreciate a copy for our review. 9. One document that was sent via email with the Notice of Application is the Biological Assessment dated August 27, 2012 is for the dredging at the Boathouse parcel (0518501150); the parcel immediately south 3342700005 (4079 Lake Washington Boulevard); and a portion of parcel 3342700007 (3909 Lake Washington Boulevard). It does not cover dredging at the other parcels noted in the NOA. 10. The assessment regarding potential salmon impacts as described in the 2012 Biological Assessment is based on limited information (i.e. Tabor et al 2004). Much more research data and information has been collected since this and should be used in a revised Biological Assessment or another environmental assessment format. For example, see http://www.goviink.org/watersheds/8/pdf/LWGI_SalmonSyn123108.pdf; http://www.goviink.org/watersheds/8/pdf/RTabor-Seattle-mtg-12-08-2010.pdf and other reports by Roger Tabor and other scientists are available. 11. Further information is also needed regarding the proposed mitigation. As part of this revised information, there should be discussion and figures showing where and what mitigation was required and completed from the previous dredging permits. With this information, the proposed mitigation for the expanded permit by parcel should be shown so reviewers can clearly see where impacts are occuring, where past mitigation has occurred, and the proposed mitigation actions. Given the site -specific and potential cumulative impacts to juvenile Chinook and other salmon species from this project, it is essential that these data/information and project detail gaps be addressed prior to the City's completion of environmental review to avoid further permitting and project details. At this time, the project has not demonstrated a "no -net loss" in part because of these data and information gaps. We appreciate the opportunity to review this proposal and look forward to reviewing the revised information that addresses the concerns and gaps described above. We may have further comments once we have reviewed this information. Please let me know if you have any questions.

NOTICE OF APPLICATION AND PROPOSED DETERMINATION OF Nan -significance -mitigated (dns-M) A Master Application has been filed and accepted with the Department of Community & Economic Development (CED) — Planning Division of the City of Renton. The following briefly describes the application and the necessary Public Approvals. DATE OF NOTICE OF APPLICATION LAND USE NUMBER: PROJECT NAME: January 13, 2017 LUA16-000977, ECF, SM Sediment Deposition Mitigation PROJECT DESCRIPTION: The applicant is requesting approval of a Shoreline Substantial Development Permit, a Hearing Examiner Special Fill and Grade Permit and Environmental (SEPA) Review to continue periodic dredging of Lake Washington in the vicinity of the May Creek Delta as a result of soil and sediment accumulation. In recent history, the area was dredged in 1994,1997, 2001/2002, and 2011. The proposed dredging project is estimated to be required every 3-5 years in order to maintain and preserve navigational access to the boathouse, shared use dock, and recreational access to Lake Washington for four (4) single-family residences (Lake Houses at Eagle Cove). Approximately 2,500 to 4,000 CY would be dredged during each dredging event. The proposed project site is located from 3905 Lake Washington Blvd N to the boat house just north of 3979 Lake Washington Blvd N (APN's 3342700011, -0009, -0007, - 0005, and 0518501150) in Renton, WA. Within Lake Washington, dredging work may also spill over onto the May Creek Delta parcel (APN 0518500000), located just north of the project site. The parcels are zoned Residential-6 (R-6) and Residential-10 (R-10). The dredging and mitigation work is anticipated to begin in the summer of 2017. PROJECT LOCATION: 3905-3979 Lake Washington Blvd N OPTIONAL DETERMINATION OF NON -SIGNIFICANCE, MITIGATED (DNS-M): As the Lead Agency, the City of Renton has determined that significant environmental impacts are unlikely to result from the proposed project. Therefore, as permitted under the RCW 43.21C.110, the City of Renton is using the Optional DNS-M process to give notice that a DNS-M is likely to be issued.

Our project team viewed the comments as constructive. Your letter is provided in Attachment A to this response 1. What is the total duration of this dredging proposal? The NO-4 describes an every 3-5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase I is a single year; however, there is no information for phase 2 and how the 10 year request was derived. Response to Comment 1. The Lake Houses at Eagle Cove (hereafter, Owners) have requested a 10 year permit from the City of Renton to conduct Sediment Deposition Mitigation dredging. If all pens nits are obtained and the Owners can proceed with Environmental Enhancement work and mitigation dredging, this first phase of the work will be completed this summer. The second phase of sediment mitigation dredging will likely occur within the next 5 years of the requested 10 year permit. Because of weather, particularly severe storm events, and unpredictable deposition patterns, there is a potential for a third dredging event. A ten year permit has been requested because the Owners have no illusions that excessive sediment deposition from the May Creek Valley will be corrected any time soon by local government. Until such measures are implemented to mitigate upstream erosion, the Owner's problem will not go away. This is why we have requested a 10 year permit. 2. More information is needed regarding the full extent of dredging. The checklist describes dredging 2,500 to 4, 000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The projects purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. Response to Comment 2.

The work would occur adjacent to a boathouse, boat ramp, and shared -used pier and may impact the May Creek. Lake Washington is a navigable Water of the U.S. regulated under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. Tributaries of Lake Washington, including May Creek, may be regulated under Section 404 of the Clean Water Act. The work that you are proposing in Lake Washington, and possibly May Creek, would likely require Department of the Army authorization through the U.S. Army Corps of Engineers. To date, a permit application for the proposed work has not been received.

Close Senior Planner Enclosure cc: Robert Cuigini / Owner and Applicant Michael Lloyd J Contact File EXHIBIT 18 1055 South Grady Way, Renton, WA 98057. rentonwa.gov Sediment Deposition Mitigation - The Lake Homes at Eagle Cove Construction Mitigation Description (5 copies) Applicability: Item 7 — Grade and Fill Permit Item 8 — Shoreline Substantial Development Permit 7.l Proposed Construction Dates In -water work at Eagle Cove will comply with the HPA (Hydraulic Project Approval) requirements provided in our recent HPA (July 2016). This "fish window" runs from July 16'b to September 150' of each year during the 5 year permit duration. The intent is to protect potential spawning salmon and other fisheries in Lake Washington and nearby May Creek. Pending approval of permits from the City of Renton, the HPA will be amended. 7.2 Days and Hours of Operation In -water work (Environmental Enhancement and Dredging) will occur during daylight hours between 7 AM and 7 PM on weekdays to minimize noise impacts to neighboring residences on weekends and evenings. Daylight hours are also substantially more protective of worker safety. Additionally, daylight hours will better allow for visual observation of dredging activities, potential turbidity generation during dredging, salmon and other fishes observation (preservation/protection), and dealing with potential emergencies that may arise. 7.3 Proposed Hauling/Transportation routes/Preliminary Traffic Control Plan The materials to be dredged are principally fine to medium sands with some gravel that is well - draining fill material. Sediments do not contain any substantial silt or clay. There are three potential options for handling this material. Option I - Off-loading at the boat ramp on Lot A and trucking the materials off site Option 2 — Off-loading the barge at a site on Lake Washington or Lake Union (TBD) Option 3 — Open Water, Ocean Disposal Option 1. It may be possible to off-load sediments directly to trucks at the Boat Ramp at Lot A. Sediments would be placed on a flat barge and allowed to "dry" to the extent that water will not leak during transit. If "free" water is observed, then trucks will be lined to eliminate drippage on public highways. The major downside to this option is having to haul sediments through the Barbee Mill Development and potentially disturb residents more than other options. Item 7 -- Construction Mitigation Description 7-1 EXHIBIT 19 Sediment Deposition Mitigation - i he Lake Homes at Eagle Cove Dry sediments would be hauled off -site for sale or other beneficial use. Clean sands are a commodity in demand, so this is a viable option in that regard. Option 2. Clean sediments can be dredged to a barge and off-loaded to another site on Lake Washington (outside of the City of Renton or Lake Union for off-loading and beneficial reuse, Currently, negotiations have been underway for a site (not in the City of Renton) that may be an opportunity for receiving sediments for beneficial reuse. For example, it may be that the City of Renton or other "lake municipalities" will have an interest in obtaining clean sands and gravels delivered to their door. Option 3. Ocean disposal is an option for receiving clean sediments from the project site at the Puget Sound Open Disposal site. Additional sediment sampling may be necessary to meet USACE requirements for ocean disposal. While ocean disposal is available, it seems to be a counter -intuitive use for clean materials that can be beneficially reused. 74 Measures to be Implemented to Minimize Dust, Erosion, Mud Dust Abatement. Because sediments are well draining, they will be damp but not wet with a low potential for generating dust. No special dust abatement measures are anticipated during dredging and handling on site. If sediments are trucked off -site, all trucks will be covered to minimize dust generation or potential wind generated loss... Erosion Control. No upland soils or structures will be impacted or modified in any way at the project site. Sediment deposition mitigation dredging should not cause any in -water impacts as regulated by the Department of Ecology in their Water Quality Certification. Potential turbidity will be monitored in real time during in -water work Dredged sediments will be placed on a flat barge that will be lined with straw bales wrapped in erosion control fabric to minimize potential turbidity in return water, as sediments further dewater in accord with anticipated Water Quality Certification. If either Option 1 or Option 2 is implemented for handling sediments, a detailed Traffic Control Plan will be generated and implemented (see section 7.5) Mud Control. Dredging operations will be conducted at all times to minimize disturbance or siltation to adjacent waters. Because dredged materials are principally sandy sediments with nominal silt or clay, virtually no mud will be generated by this project. In the event of excessive turbidity, fish distress, fish kill, or other water quality problem, dredging operations and placement will be stopped until the problem is corrected, and the Department of Ecology has been notified. Noise Control. Dredging will occur during daylight hours to minimize noise to neighboring businesses and residences during weekend and nighttime hours. Some temporary increase in noise is unavoidable from the operation of heavy equipment. Noise levels will approximate those generated by equipment operated at the former sawmill. Potential noise impacts may be limited by utilizing equipment that is well muffled. Because sound travels over water Item 7 — Construction Mitigation Description 7-2 Sediment Deposition Mitigation - The Lake Homes at Eagle Cove very well, baffles on the dredging equipment will be installed if noise levels are unacceptable. Other Noxious Characteristics. Sediments have been previously sampled and tested for potential contamination. Test results from multiple testing events over the years indicate that sediments are clean sands and gravels. No sediment quality criteria have been exceeded, and sediments present no substantial environmental threat to human health or the environment. Nevertheless, a spill of petroleum products (hydraulic fluid, diesel, other) is always a concern. All equipment operating over -water will be enclosed with a containment boom to capture a potential spill and to aid in cleanup by not allowing a potential spill to spread or disperse. Most dredging contractors now use a peanut or other vegetable —based hydraulic oil to minimize petroleum releases. Contractors will carry spill control materials on board floating equipment so that in the event of a spill or leak, there will be no delay in containment to minimize potential impacts. An approved Spill Control and Countermeasures Plan (SPCC Plan) is required by the Coast Guard for all equipment operating in/over water. A copy of the selected contractor's plan will be provided to the City of Renton. This plan will be implemented in case of a spill, or leak. Because of this potential for a spill, prevention and a proactive approach is always the best measure. A trained and educated work force, trained in spill protection and cleanup is essential. Additionally, it is critical that all equipment is maintained in good operating condition and all hydraulic lines and fittings be routinely inspected on a daily basis. The most common leak to the waters of the state arises from failing hydraulic hoses and fittings. Refueling of equipment over the water will not be allowed during the short duration of the project. . These risks can and will be minimized with maintained equipment, trained personnel, equipment inspections, containment booms, and related proactive measures to minimize the potential impacts arising from a spill or a leak into the waters of the state.. 7.5 Preliminary Traffic Control Plan In Section 7.2 above, we detailed and discussed the primary options for beneficial reuse or disposal of sediments. A full traffic control plan will be prepared, and submitted to the City of Renton for review and approval of a "hauling permit" if dredged materials are trucked off site on public highways. It is currently anticipated that approximately 2,500 to 3,000 CY of sandy sediments will be moved during the next dredging event. This would translate to approximately 350 truck loads. If tandem trucks are used, the number of trips would be reduced by 50%. If dredging occurs over 10 day period, that would equate to approximately 35 tandem trucks per day during approved hauling times of lower traffic volume. Hauling of sediments will not occur on weekends. The preliminary haul route for trucks will leave the project site is as follows: • Travel north on Lake Washington Boulevard N, • Continue to destination on I-405. Item 7 — Construction Mitigation Description 7-3 Sediment Deposition Mitigation - x he Lake Homes at Eagle Cove Off site movement of dredged materials will comply with Traffic control permit requirements detailed below: • Obtain City approval of the Traffic Control Plan in compliance with the Manual on Uniform Traffic Control Devices. • Comply with all traffic regulations of the City of Renton and the State of Washington. • No street or lane closures are anticipated. • Notify emergency services (253-852-2121) as soon as possible for any street or lane closures in the event of a truck break down or other traffic impediment. • Indemnify and hold harmless the City of Renton from any and all claims, actions, and judgments, including all costs of defense and attorney's fees incurred in defending against same, arising from and related to implementation of the approved traffic control plans including claims arising from towing of private vehicles and the acts of the Permit Holder's agents and employees. • The City of Renton shall be entitled, in its reasonable discretion, to settle claims prior to suit or judgment, and in such event shall indemnify and hold harmless the City for any such claims paid, including the City's reasonable attorney's fees and litigation costs incurred resulting from such claim, • In the event any claim or suit is brought against City within the scope of this Agreement, Permit Holder will pay for legal counsel chosen by the City to defend against same. • Flagger and sign placement are subject to revision by the City Inspector on site, if needed to address traffic or pedestrian safety or travel. • Work Zone Traffic Control shall be in accordance with the Manual on Uniform Traffic Control Devices (MUTCD) and shown by sketch or reference to WSDOT. • The plan must be submitted to the City's PW/Transportation Division for review and/or approval at least three working days prior to work. • Approved Temporary Traffic Control Plan must be at the work site during work hours. • Contractor or entity must call Renton School District (425-204-4455) or any public/private agency to be affected by a temporary lane or road closure. • -Complete assistance and accommodation shall be provided to all kinds of pedestrian traffic when sidewalk or walkway is impeded. • Total road closure lasting more than 24 hours is subject to the approval by the City Council. • Any vehicle, equipment, barricade, or portable tow -away sign used within the work area must display a company logo or any legally acceptable sign showing the company name, address, and telephone number at a conspicuous place on the vehicle or equipment.

The NOA describes an every 3 5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year; however, there is no information for phase 2 and how the 10 year request was derived_ 2. More information is needed regarding the full extent of dredging. The checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. 3. It is our understanding that a 10 year dredging permit was issued and modified for parcel 0518601150 (Cuigini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. As part of the Notice of Application, City staff indicated that the dredging work may inadvertently spill over onto the May Creek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in Lake Washington. Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specifically stated that the dredging a 10,000 square foot area by 2 feet every 3 5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the following: a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented. An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; b. A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown; and G. The location and success of previous mitigation measures for the previously permitted dredging work. 5. Also parcel 3342700009 (3907 Lake Washington Blvd N) currently does not have a dock or any structure that provides moorage_ Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of important shallow water habitat for juvenile salmon as the moorage needs can be accommodated by other means (i.e. expansion of existing joint moorage facilities, buoys, etc.). 6. Please provide additional information regarding the necessary navigational depth profile for each parcel, This information should be presented parcel by parcel in a table. 7_ Please provide monitoring data from previous dredging work. It is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. 8.

Clark Close 1425-430-7289, coos rend nwa,gov RESOLVED: 1. What is the total duration of this dredging proposal? The NOA describes an every 3 5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year; however, there is no information for phase 2 and how the 10 year request was derived. 2. More information is needed regarding the full extent of dredging. The checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. 3. It is our understanding that a 10 year dredging permit was issued and modified for parcel 0518501150 (Cuigini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. As part of the Notice of Application, City staff indicated that the dredging work may inadvertently spill over onto the May Creek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in Lake Washington. Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11. 2007 specifically stated that the dredging a 10,000 square foot area by 2 feet every 3 5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feel without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the following: a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented. An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; b. A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown; and c. The location and success of previous mitigation measures for the previously permitted dredging work. 5. Also parcel 3342700009 (3907 Lake Washington Blvd N) currently does not have a dock or any structure that provides moorage_ Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of important shallow water habitat for juvenile salmon as the moorage needs can be accommodated by other means (i.e. expansion of existing joint moorage facilities, buoys, etc_). 6. Please provide additional information regarding the necessary navigational depth profile for each parcel_ This information should be presented parcel by parcel in a table. 7. Please provide monitoring data from previous dredging work. It is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. 8. One document that was sent via email with the Notice of Application is the Biological Assessment dated August 27, 2012 is for the dredging at the Boathouse parcel (0518501150); the parcel immediately south 3342700005 (3979 Lake Washington Blvd N); and a portion of parcel 3342700007 (3909 Lake Washington Blvd N). It does not cover dredging at the other parcels noted in the master land use application or NOA. Please indicate the control mechanism to avoid any spill over onto the May Creek Delta parcel (APN 0518500000) and why dredging work of parcels 3342700009 (3907 Lake Washington Blvd N) and 3342700011 (3905 Lake Washington Blvd N) were included in the proposal. 9. The assessment regarding potential salmon impacts as described in the 2012 Biological Assessment is based on limited information (Le. Tabor et al 2004).

In recent history, the area was dredged in 1994, 1997, 2001/2002, and 2011. The proposed dredging project is estimated to be required every 3-5 years to maintain and preserve navigational access to the boathouse, shared use dock, and recreational access to Lake Washington for four (4) single-family residences (Lake Houses at Eagle Cove). Approximately 2,500 to 4,000 CY would be dredged during each dredging event. The proposed project site is located from 3905 Lake Washington Blvd N to the boat house just north of 3979 Lake Washington Blvd N (APN's 3342700011, -0009, -0007, -0005, and 0518501150) in Renton, WA. The parcels are zoned Residential-6 (R-6) and Residential-10 (R-10). The dredging and mitigation work is anticipated to be conducted in two phases, beginning in 2017.

BOX 3765 SEATTLE, WASHINGTON 98124.3755 FEB — 5 2016 Reference: N W S-2007-1 O I 9 Barbee Company We have received your request for a permit modification to modify the approved plans and extend the time limit for completing the work authorized by the above-refereaced Department of the Army permit. The permit authorizes the dredging of up to 4,000 cubic yards of sediment over a 10,000-square-foot area; renovation of a boathouse, placement of spawning gravel, and the replacement of floats in Lake Washington at Renton, Washington. The original time limit for completing the authorized dredging is scheduled to expire on January 8, 2019. You have requested a modification of the permit to dxedge up to an additional 2,700 cubic yards over an additional 14,000-square-foot area; replace an existing solid wood float and three creosote - treated piles with a grated float and two galvanized steel piles; and replace two 3-pile dolphins with two galvanized steel piles. Your request for a permit modification and time extension is approved. Enclosed are the approved modified plans dated August 21, 2012, which supersede plans authorized by the Secretary of the Army on January 8, 2009. The new time limit for completing the authorized dredging ends 10 years from the date of this approval letter, The new time limit for completing the other authorized work ends 3 years from the date of this approval letter_ We have modified three of the original conditions as a result of our recent permit review as follows: d. You must implement and abide by the Endangered Species Act (ESA) requirements and/or agreements set forth in the Cugini Property Boathouse Expansion of the .Existing Lake Washington Dredge Prism Biological Assessment dated August 27, 2012, and the addendum dated April 3, 2014, in thew entirety. The U.S. Fish and Wildlife Service (USFWS) concurred with a finding of "may affect, not likely to adversely affect" based on this document on May 15, 2014 (USFWS Reference Number 13410-2008-I-0149). The USFWS will be informed of this permit issuance. ,Failure to comply with the commitments made in this document -2- constitutes non, -compliance with the ESA and your U.S. Arrny Corps of Engineers permit_ The USFWS is the appropriate authority to determine compliance with ESA. e. This U.S. Army Corps of Engineers (Corps) permit does not authorize you to take a threatened or endangered species, in particular the Puget Sound Chinook and steelhead. In order to legally take a listed species, you must have a separate authorization under the Endangered Species Act (ESA) (e.g., an ESA Section 10 permit, or ESA Section 7 consultation Biological Opinion (BO) with non -discretionary "incidental take" provisions with which you must comply). The enclosed BO prepared by the National Marine Fisheries Service (NMFS) dated October 6, 2014, contains mandatory ter7rrs and conditions to implement the reasonable and prudent measures that are associated with the specified "incidental take" in the BO (TIMES Reference Number WCR-2014-770). Your authorization under this Corps permit is conditional upon your compliance with all of the mandatory terms and conditions associated with incidental take of the enclosed BO. These terms and conditions are incorporated by reference in this permit. Failure to comply with the terms and conditions associated with incidental take of the BO, where a take of the listed species occurs, would constitute an unauthorized take, and it would also constitute non-compliance with your Corps permit. The NMFS is the appropriate. authority to determine compliance with the terms and conditions of its BO and with the ESA. f. In order to meet the requirements of the Endangered Species Act you may conduct the authorized activities from July 16 through September 15 in any year this permit is valid. You shall not conduct work authorized by this permit from September 16 through July 15 in any year this permit is valid. We have added the following three permit conditions as a result of our recent permit review: m.. Any deviations from the authorized dredging footprint or depths must be reported to the Regulatory Branch Project Manager within 24 hours of discovery. n. Plotted results of the post -dredge bathymetric survey shall be submitted to the U,S. Army Corps of Engineers, Seattle District, Dredged Material Management Office and Regulatory Branch Project Manager in PDF format within 30 days of completion of dredging. Results must clearly display the post -dredge sediment surface in relation to the permitted dredge boundary and depth, as well as the location of project features such as docks, wharfs and other landmarks. The vertical datum must be clearly indicated. full bathymetric survey data must be submitted upon request. o. At least four months prior to each maintenance dredging activity, the permittee must contact the U.S. Army Corps of Engineers, Dredged Material Management Office to determine whether additional sediment characterization is required. If additional characterization is required, no dredging will be allowed until the sediment surface that will be left after dredging has been determined to meet the Dredged Material Management Program's anti -degradation guidelines. -3- Please be reminded that Special Conditions "d" and "e" of your permit require that you implement and abide by the ESA. requirernents and/or agreements set forth in the Biological Evaluation and/or the BO for this project. In particular, note that these documents require that you replace a solid float and creosote -treated piling with a grated float and steel piling; and place. 20 cubic yards of gravel. Failure to comply with the commitments made in these documents constitutes non-compliance with the ESA. and your Corps permit. All other terms and conditions contained in the original permit remain in lull force and effect.

E. "Chip" Vincent, Administrator "On Hold" Notice Sediment Deposition Mitigation, LUA16-000977, ECF, SM Dear Mr. Lloyd: The Planning Division of the City of Renton accepted the above master application for review on January 13, 2017. During our review, staff has determined that additional information is necessary in order to proceed further. The following information will need to be submitted before May 3, 2017 so that we may continue the review of the above subject application: ■ On January 27, 2017, Karen Walter with the Muckleshoot Indian Tribe Fisheries Division provided agency comments regarding the subject application. Given the site -specific and potential cumulative impacts to juvenile Chinook and other salmon species from this project, it is essential that these data/information and project detail gaps be addressed prior to the City's completion of environmental review to avoid further permitting and project details. At this time, the project has not demonstrated a "no -net loss" in part because of these data and information gaps. The questions raised by the Muckleshoot Indian Tribe Fisheries Division have been modified slightly to give you opportunity to comment on each question. 1. What is the total duration of this dredging proposal? The NOA describes an every 3-5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year; however, there is no information for phase 2 and how the 10 year request was derived. 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov 1 2. More information is needed regarding the full extent of dredging. The checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. 3. It is our understanding that a 10-year dredging permit was issued and modified for parcel 0518501150 (Cuigini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. As part of the Notice of Application, City staff indicated that the dredging work may inadvertently spill over onto the May Creek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in Lake Washington. Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specifically stated that the dredging a 10,000 square foot area by 2 feet every 3-5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the following: a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented. An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov t b. A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown; and c. The location and success of previous mitigation measures for the previously permitted dredging work. 5. Also parcel 3342700009 (3907 Lake Washington Blvd N) currently does not have a dock or any structure that provides moorage. Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of important shallow water habitat for juvenile salmon as the moorage needs can be accommodated by other means (i.e. expansion of existing joint moorage facilities, buoys, etc.). 6. Please provide additional information regarding the necessary navigational depth profile for each parcel. This information should be presented parcel by parcel in a table. 7. Please provide monitoring data from previous dredging work. It is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. 8. One document that was sent via email with the Notice of Application is the Biological Assessment dated August 27, 2012 is for the dredging at the Boathouse parcel (0518501150); the parcel immediately south 3342700005 (3979 Lake Washington Blvd N); and a portion of parcel 3342700007 (3909 Lake Washington Blvd N). It does not cover dredging at the other parcels noted in the master land use application or NOA. Please indicate the control mechanism to avoid any spill over onto the May Creek Delta parcel (APN 0518500000) and why dredging work of parcels 3342700009 (3907 Lake Washington Blvd N) and 3342700011 (3905 Lake Washington Blvd N) were included in the proposal. 9. The assessment regarding potential salmon impacts as described in the 2012 Biological Assessment is based on limited information (i.e. Tabor et al 2004). Much more research data and information has been collected since this and should be used in a revised Biological Assessment or another environmental assessment format. See http://www.govlink.org/watersheds/8/pdf/LWGI SalmonSyn123108.pdf; http://www.govlink.org/water sheds/8/pdf/RTabor-Seattle-mtg-12-08-2010._pdf and other reports by Roger Tabor and other scientists are available. 10.

The following briefly describes the application and the necessary Public Approvals. DATE OF NOTICE OF APPLICATION LAND USE NUMBER - January 13, 2017 LUA16-000977, ECF, SM Sediment Deposition Mitigation PROJECT DESCRIPTION: The applicant is requesting approval of a Shoreline Substantial Development Permit, a Hearing Examiner Special Fill and Grade Permit and Environmental (SEPA) Review to continue periodic dredging of Lake Washington in the vicinity of the May Creek Delta as a result of soil and sediment accumulation. In recent history, the area was dredged in 1994, 1997, 2001/2002, and 2011. The proposed dredging project is estimated to be required every 3-5 years in order to maintain and preserve navigational access to the boathouse, shared use dock, and recreational access to Lake Washington for four (4) single-family residences (Lake Houses at Eagle Cove). Approximately 2,500 to 4,000 CY would be dredged during each dredging event. The proposed project site is located from 3905 Lake Washington Blvd N to the boat house just north of 3979 Lake Washington Blvd N (APN's 3342700011, - 0009, -0007, -0005, and 0518501150) in Renton, WA. Within Lake Washington, dredging work may also spill over onto the May Creek Delta parcel (APN 0518500000), located just north of the project site. The parcels are zoned Residential-6 (R-6) and Residential-10 (R-10). The dredging and mitigation work is anticipated to begin in the summer of 2017. PROJECT LOCATION: 3905-3979 Lake Washington Blvd N OPTIONAL DETERMINATION OF NON -SIGNIFICANCE, MITIGATED (DNS-M): As the Lead Agency, the City of Renton has determined that significant environmental impacts are unlikely to result from the proposed project. Therefore, as permitted under the RCW 43.21C.110, the City of Renton is using the Optional DNS-M process to give notice that a DNS-M is likely to be issued. Comment periods for the project and the proposed DNS-M are integrated into a single comment period.

The permits are approved subject to conditions. Testimony Clark Close, City of Renton Senior Planner, summarized the staff report. Michael Lloyd, applicant representative, noted that the applicant has recently acquired approval from the Army Corps of Engineers for the option of disposing dredge materials in Elliot Bay. However, the preferred disposal option is beneficial re -use in road projects and the like as opposed to dumping the dredge materials into Elliot Bay. Mr. Lloyd explained the dredging is necessary to access the boathouse. It's difficult to estimate the amount of material that needs to be dredged because of the unpredictability of May Creek and what it will deposit near the boathouse. The name of the permit is misleading because no fill is involved.

Michael Lloyd, Lloyd & Associates, Inc., 255 Camaloch Dr, Camano Island, WA, 98282 2. Hearing. A hearing on the applications was held on April 18, 2017 in the City of Renton City Council meeting chambers at Renton City Hall. Substantive: 3. Description of Proposal. The applicant has applied for a Special Fill and Grade Permit and a Shoreline Substantial Development Permit to do some dredging in Lake Washington near the May Creek Delta to clear away sediment deposition from May Creek that is blocking access to a boathouse and shared use dock serving four homes in Eagle Cove. Approximately 2,500 to 4,000 CY would be dredged during each dredging event. In recent history, the area was dredged in 1994, 1997, 2001/2002, and 2011. The proposed dredging project is estimated to be required every 3-5 years. The proposed project site is located from 3905 Lake Washington Blvd N to the boat house just north of 3979 Lake Washington Blvd N (APN's 3342700011, -0009, -0007, -0005, and 0518501150) in Renton, WA. The dredging and mitigation work is anticipated to be conducted in two phases and potentially a third, beginning in 2017. The applicant is proposing to continue periodic dredging of depositional sediments that have accumulated within Lake Washington, near the May Creek Delta, for a period of 10 years for a maximum of three phases of dredging. The proposed profile is not anticipated to reach depths that would encounter sediments that are older than dredging work completed in 2011 or in previous dredging events. Dredge work would require approximately 80 hours over a 10-day period. 4. Adverse_ Impacts. There are no significant adverse impacts associated with the proposal as mitigated. Pertinent impacts are individually addressed as follows: A. Ecological Function. The proposal will result in no net loss of ecological function. This SPECIAL GRADE/FILL PERMIT AND SSDP - 2 a 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 conclusion was reached in a lake study, Ex. 13, prepared by Meridian Environmental, Inc.. The conclusions of the lake study were based upon a detailed and thorough review of environmental impacts and application of numerous studies based upon best available science. As to background conditions, numerous salmonid species have been documented at or near the proposed project site, including coho, Chinook, and sockeye salmon. The salmonids are listed in the Washington State Department of Wildlife Priority Habitats and Species data base. Other fish such as bass perch, rainbow trout/steelhead and cutthroat trout have also been documented near the project site. Six species of aquatic macrophytes have also been documented in the project vicinity. With recommended mitigation measures, the study concluded that the proposal would maintain and possibly improve water quality; enhance aquatic habitat and hydraulic functions in lower May Creek; slightly increase primary productivity and near -shore habitat quality in Lak Washington; and reduce predation in the project area. Based on these factors, the lake study concluded that the proposal would create no net loss of shoreline ecological functions. A biological assessment was also prepared for the project, Ex. 12. The biological assessment identified that the Chinook salmon, steelhead and bull trout are documented at the project area and are listed as threatened under the ESA and that the coho salmon are classified as a species of concern. The biological assessment concluded that with recommended mitigation the proposal "may affect," but is "not likely to adversely affect" Chinook, steelhead, and bull trout. As to impacts to fish habitat, the study concluded that with recommended mitigation that water quality would improve; primary productivity and fish forage base would be improved; and shoreline and instream habitat quality would be improved. There is no evidence in the record that is contrary to the conclusions and analysis of the lake study and biological assessment. The two studies were very thorough, based upon best available science and professionally done. The mitigation measures recommended in the studies are imposed by the MDNS. From these studies and the mitigation measures it is concluded that the proposal will not result in a net loss of ecological function. B. Stormwater. There will be no unpermitted runoff, including stormwater at the project dredge area. The proposal would not alter or otherwise affect drainage patterns in the vicinity of the site. C. Noise. The applicant has indicated that operation of dredging equipment and upland heavy equipment {frontend loaders, etc.} would generate expected noise levels during construction of up to 80 to 90 decibels on a short-term basis only during construction. No long-term noise levels would be created. Construction noise would only occur during SPECIAL GRADE/FELL PERMIT AND SSDP - 3 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 PW daylight hours. The short 10-day dredging period dictates the impacts would be temporary. No unusual noise impacts are proposed, which would require further levels of noise mitigation. To ensure that the public is notified of the proposed dredging activities in a timely manner, a condition of approval requires that the applicant develop a public notification plan complete with temporary signage, subject to approval of staff. D. Aesthetics. The staff report does not identify the aesthetic impact of the proposal. It appears from the staff report that the equipment will be limited to a barge. Considering the short ten day dredging period, it is determined that the presence of a barge along the shoreline will not create any unreasonable unsightliness or significant adverse aesthetic impacts. E. Traffic. As mitigated, the proposal will not create any significant traffic impacts. The applicant has specified that the disposal of the excavated sediment would be transported one of three ways: hauled off -site, off-loaded at a site on Lake Washington, or open water/ocean disposal. If either of the first two ways are selected for handling sediments, a detailed Traffic Control Plan would need to be submitted and approved by the City of Renton prior to the start of construction. F. Navi atg io�nXgblic Access/Recreation. The proposal will significantly improve navigation, recreation and public shoreline access near the applicant's boathouse and community dock by removing sedimentary obstacles to boat passage, consistent with its purpose. Conclusions of Law Procedural: 1. Authority of Hearing Examiner. RMC 4-9-080(F)(1)(a) provides that the hearing examiner is responsible for granting permits for fill and grade that involves excavation of more than 500 cubic yards. The proposal dredging will involve at least 2,000 cubic yards. Shoreline substantial development permits are classified by RMC 4-8-080(G) as Type II permits (subject to staff as opposed to hearing examiner review). The shoreline permit of this case has been consolidated with the special grade and fill permit review as Type III review overall pursuant to RMC 4-8-080(C). Substantive: 2. Applicable Standards. RMC 4-9-080(F)(4) governs the criteria for special fill/grade permits. The criteria for shoreline substantial development permits is set by RMC 4-9-190(B)(7), which requires compliance with all City of Renton Shoreline Master Program ("SMP") use regulations and SMP policies. Applicable standards are quoted below in italics and applied through corresponding conclusions of law. SPECIAL GRADEXILL PERMIT AND SSDP - 4 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Fill and Grade Permit RMC 4-9-080(F')(4):... To grant a special permit, the Hearing Examiner shall make a determination that.. the proposed activity would not be unreasonably detrimental to the surrounding area. The Hearing Examiner shall consider, but is not limited to, the following: i. Size and location of the activity. ii. Traffic volume and patterns. iii. Screening, landscaping, fencing and setbacks. iv. Unsightliness, noise and dust. v. Surface drainage. vi. The length of time the application of an existing operation has to comply with nonsafety provisions of this Title. 3. The primary impact of concern would be impacts to sensitive environmental resources. As determined in Finding of Fact No. 5, the proposal will not result in a net reduction of shoreline ecological function. Other pertinent impacts are also addressed in Finding of Fact No. 5 to the extent relevant to the criterion quoted above. Since none of the impacts qualify as significantly adverse, the criterion is met. Shoreline Permit RMC 4-9-190(B)(7): In order to be approved, the Administrator of the Department of Community and Economic Development or designee must find that a proposal is consistent with the following criteria: a.

Comprehensive Plan Compliance: The site is designated Residential Medium Density (RMD) and Residential High Density (RHD) on the City's Comprehensive Plan Map. The purpose of the RMD designation is to allow a variety of single-family and multi -family development types, with continuity created through the application of design guidelines, the organization of roadways, sidewalks, public spaces, and the placement of community gathering places and civic amenities. RHD unit types are designed to incorporate features from both single-family and multi -family developments, support cost- efficient housing, facilitate infill development, have close access to transit service, and efficiently use HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development Hearing Examiner Recommendation SEDIMENT DEPOSITION MITIG, V tUA16-000977, ECF, SM Report of April 18, 2017 Page 5 of 25 urban services and infrastructure. Lands designated RHD is where projects will be compatible with existing uses and where infrastructure is adequate to handle impacts from higher density uses. The City adopts the goals and principles of the Shoreline Management Act as provided in RCW 9058.020 and as particularly relevant to Renton. The proposal is compliant with the following Comprehensive Plan Goals and Policies if all conditions of approval are met: Compliance I Comprehensive Plan Analysis Goal L-P: Minimize adverse impacts to natural systems, and address impacts of past ✓ practice where feasible, through leadership, policy, regulation, and regional coordination. Goal L-U: Preserve, protect, and enhance the quality and functions of the City's sensitive areas including: lakes, rivers, major and minor creeks, intermittent stream courses and their floodplains, wetlands, ground water resources, wildlife habitats, and areas of seismic and geological hazards. Policy L-29: Minimize erosion and sedimentation in and near sensitive areas by ,i requiring appropriate construction techniques and resource practices, such as low impact development. Policy L-32: Protect buffers along wetlands and surface waters to facilitate infiltration .� and maintain stable water temperatures, provide for biological diversity, reduce amount and velocity of run-off, and provide for wildlife habitat. Policy L-55: Protect public scenic views and public view corridors, including Renton's physical, visual and perceptual Wkages to Lake Washington and the Cedar River. Policy L-56: Preserve natural landforms, vegetation, distinctive stands of trees, natural slopes, and scenic areas that contribute to the City's identity, preserve property values, and visually define the community and neighborhoods. Goals and Principals SM-3: Much of the shoreline jurisdiction and the uplands adjacent thereto are in private ownership. Unrestricted construction on the privately owned or publicly owned shorelines is not in the best public interest; therefore, coordinated planning is necessary in order to protect the public interest associated with the shoreline jurisdiction while recognizing and protecting private property rights consistent with the public interest. Goals and Principals 5M-7: In the implementation of the Shoreline Master Program, the public's opportunity to enjoy the physical and aesthetic qualities of natural shorelines shall be preserved to the greatest extent feasible consistent with the overall best interest of the state, the county, and the people generally. To this end, uses shall be preferred which are consistent with control of pollution and prevention of damage to the natural environment or are unique to or dependent upon use of the state's shoreline. Goals and Principals 5M-8: Alterations of the natural condition of the shoreline, in those limited instances when authorized, shall be given priority for single family residences and their appurtenant structures; ports; shoreline recreational uses including but not limited to parks, marinas, piers, and other improvements facilitating public access to shorelines; industrial and commercial developments that are particularly dependent on their location on or use of the shoreline jurisdiction; and HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development Hearing Examiner Recommendation SEDIMENT DEPOSITION MITIG) V LUAI6-000977, ECF, 5M Report of April 18, 2017 Page 6 of 25 other development that will provide an opportunity for substantial numbers of the people to enjoy the shorelines. Goals and Principals SM-9: Permitted uses in the shorelines zone shall be designed and conducted in a manner to minimize, insofar as practical, any resultant damage to the ecology and environment of the shoreline jurisdiction and any interference with the public's use of the water. 20. Zoning Development Standard Compliance: The site is classified as Residential-6 (R-6) and Residential- 10 (R-10) on the City's Zoning Map. Development in the R-6 zone is intended to be single family residential at moderate density. The Residential-10 Zone (R-10) is established for high -density residential development that will provide a mix of residential styles including small lot detached dwellings or attached dwellings such as townhouses and small-scale flats. The zone serves as a transition to higher density multi -family zones. The proposal is compliant with the following development standards if all conditions of approval are met: Compliance R-6 and R-10 Zone Develop Standards and Analysis Density: The density range permitted in the R-6 zone is a minimum 3.0 up to a maximum of 6.0 dwelling units per net acre. Net density is calculated after the deduction of sensitive areas, areas intended for public right-of-way, and private N/A access easements. The density range permitted in the R-10 zone is a minimum 5.0 up to a maximum of 10.0 dwelling units per net acre. Net density is calculated after the deduction of sensitive areas, areas intended for public right-of-way, and private access easements. Lot Dimensions: The minimum lot size permitted in the R-6 zone is 7,000 sq. ft. A minimum lot width of 60 feet is required (70 feet for corner lots) and a minimum lot depth of 90 feet is required. N/A The minimum lot size permitted in the R-10 zone is 4,000 sq. ft. for detached dwellings. There is no minimum lot size for attached dwellings. A minimum lot width of 40 feet is required (50 feet for corner lots) and a minimum lot depth of 70 feet is required. Setbacks: The required setbacks in the R-6 zone are as follows: front yard is 25 feet, side yard is combined 15 feet with not less than 5 feet on either side, side yard along the street 25 feet, and the rear yard is 25 feet. The required setbacks in the R-10 zone are as follows: front yard is 20 feet except when all access is taken from an alley then 15 feet, side yard is 4 feet for detached units, for attached dwellings the side yard is 0 feet for attached sides and 4 feet for unattached sides, side yard along the street 15 feet, and the rear yard is 15 feet. Staff Comment: North of the former Barbee Mill facility (approximately 2,000 ft), is Quendall Terminals (QT) a former industrial property, currently vacant, consisting of approximately 22 acres of relatively flat land, with approximately 1,500 feet of Lake Washington shoreline zoned Commercial Office Residential (COR). As one of the possible options for handling the dredged sediment, the applicant is exploring the possibility of off-loading and stockpiling up to 4,000 cubic yards of clean sediments dredged from the Lake Houses at Eagle Cove Eagle Cove on the southeast corner of the QT site. The stockpiled material could be beneficially reused as capping material during future remedial efforts at QT. In order to stockpile material on the QT site, the applicant would be required to complete a Temporary Use Tier it and comply with HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development SEDIMENT DEPOSITION MITIQ Report of April 19, 2017 V Hearing Examiner Recommendation LUA16-000977, ECF, SM Page 7 of 25 minimum setback standards. Conditions of approval would be subject to minimum setback requirements of the zone. Specifically, the stockpiled material would be required to be set back over 100 feet from the shoreline, set back at least 25 feet from all other property boundaries, and demonstrate that no impacts would occur to critical areas and their buffers. Building Standards: The R-6 zone has a maximum building coverage of 40% and a maximum impervious surface coverage of 55%. A Code Interpretation (CI-73) (Exhibit 29) was adopted regarding building height requirements. In the R-6 zone, a maximum building height of 2 stories with a wall plate height of 24 feet is permitted. Roofs with a pitch equal to or greater than 4:12 may project an additional six (6) vertical feet from the maximum wall plate height; common rooftop features, such as chimneys, may project an additional four (4) vertical feet from the roof surface. Non- exempt vertical projections (e.g., decks, railings, etc.) shall not extend above the maximum wall plate height unless the projection is stepped back one -and -a -half (1.5) horizontal feet from each facade for each one (1) vertical foot above the maximum wall plate height. Reserved. The R-10 zone has a maximum building coverage of 55% and a maximum impervious surface coverage of 70%. In the R-10 zone, a maximum building height of 2 stories N/A with a wall plate height of 24 feet is permitted. Roofs with a pitch equal to or greater than 4:12 may project an additional six (6) vertical feet from the maximum wall plate height. If the height of wall plates on a building are less than the states maximum the roof may project higher to account for the difference, yet the combined height of both features shall not exceed the combined maximums. Common rooftop features, such as chimneys, may project an additional four (4) vertical feet from the roof surface. Non-exempt vertical projections (e.g., roofs pitched less than 4:12, decks, railings, etc.) may extend up to six (6) vertical feet above the maximum wall plate height if the projection is stepped back one -and -a -half (1.5) horizontal feet from each minimum building setback line for each one (1) vertical foot above the maximum wall plate height. Wall plates supporting a primary roof surface that has only one (1) sloping plane (e.g., shed roof) may exceed the stated maximum if the average of wall plate heights is equal or less than the maximum wall plate height allowed. Landscaping: The City's landscape regulations (RMC 4-4-070) require a 10-foot landscape strip along all public street frontages. Additional minimum planting strip widths between the curb and sidewalk are established according to the street development standards of RMC 4-6-060. Street trees and, at a minimum, groundcover, are to be located in this area when present. Spacing standards shall be N/A as stipulated by the Department of Community and Economic Development, provided there shall be a minimum of one street tree planted per address. Any additional undeveloped right-of-way areas shall be landscaped unless otherwise determined by the Administrator. Where there is insufficient right-of-way space or no public frontage, street trees are required in the front yard subject to approval of the Administrator. A minimum of two trees are to be located in the front yard prior to final inspection for the new Single Family Residence. Tree Retention: The City's adopted Tree Retention and Land Clearing Regulations NSA require the retention of 30 percent of trees in a residential development. Significant trees shall be retained in the following priority order: HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development SEDIMENT DEPOSITION MITIGi V Report of April 18, 2017 Hearing Examiner Recommendation LUA16-000977, ECF, SM Page 8 of 25 Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on slopes greater than twenty percent (20%); Significant trees adjacent to critical areas and their associated buffers; and Significant trees over sixty feet (60') in height or greater than eighteen inches ( 18") caliper. Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and Other significant non- native trees. Priority Three: Alders and cottonwoods shall be retained when all other trees have been evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods are used as part of an approved enhancement project within a critical area or its buffer. A minimum tree density shall be maintained on each residentially zoned lot. For detached single family development, the minimum tree density is two (2) significant trees for every five thousand (5,000) square feet. The tree density may consist of existing trees, replacement trees, trees required pursuant to RMC 4-4-07OF1, Street Frontage Landscaping Required, or a combination. Parking: Parking regulations require that a minimum of two parking spaces be provided for each detached dwelling. Driveway cuts are required to be a minimum of 5 feet from property lines and new N/A driveways may be a maximum of 16 feet in width at the property line. Maximum driveway slopes shall not exceed fifteen percent (15%); provided, that driveways exceeding eight percent (8%) shall provide slotted drains at the lower end with positive drainage discharge to restrict runoff from entering the garage/residence or crossing any public sidewalk. Fences and Retaining Walls: In any residential district, the maximum height of any fence, hedge or retaining wall shall be seventy two inches (72"). Except in the front yard and side yard along a street setback where the fence shall not exceed forty N/A eight inches (48") in height. There shall be a minimum three-foot (3') landscaped setback at the base of retaining walls abutting public rights -of -way. 21. Critical Areas: Project sites, which contain critical areas, are required to comply with the Critical Areas Regulations (RMC 4-3-050). A Sediment Sampling and Analytical Results Report (revised date December 12, 2016; Exhibit 9) and a Biological Assessment prepared by Meridian Environmental, Inc. (dated August 27, 2012; Exhibit 11) with the submitted application materials. According to the submitted reports, no critical areas were identified on the project site. See Environmental Review Committee Report (Exhibit 1) for more information. 22. Shoreline Substantial Development Permit: The jurisdictional area is located and composed of aquatic lands in Lake Washington. Pursuant to Chapter 90.58 RCW, staff recommends granting a Shoreline Substantial Development Permit (SSDP). The granting of the SSDP would be pursuant to the Shoreline Management Action of 1971 and the following: The issuance of a license under the Shoreline Management Act of 1971 shall not release the applicant from compliance with federal, state, and other permit requirements. Construction permits shall not be issued until twenty-one (21) days after approval by the Washington State Department of Ecology or until any review proceedings initiated within this twenty-one (21) day review period have been completed.

COMPREHENSIVE PLAN COMPLIANCE AND CONSISTENCY, SHORELINE ELEMENT: The site is located in the Shoreline Isolated High -intensity Overlay District. The objective of the High Intensity Overlay — Isolated Lands overlay is to provide appropriate regulations for areas that are within shoreline jurisdiction but are with separate parcels effectively isolated from the water by intervening elements of the built environment, largely consisting of railroads and roads or intervening private parcels. In most cases, these areas function as parallel designations with other designations applied to the area adjacent to the water. The proposal is compliant with the following Shoreline policies If conditions of approval are met: Policy SH-7: Existing and future activities on all Shorelines of the State regulated by the City of Renton should be designed to ensure no net loss of ecological functions. Staff Comment: The applicant submitted a Sediment Sampling and Analytical Results Report (revised date December 12, 2016; Exhibit 9) along with Geotechnical Design Parameters for Anchor Piles prepared by Geotech Consultants, Inc. (dated January 10, 2010; Exhibit 10) and Geotechnical Observations during Pile installation prepared by Geotech Consultants, inc. (dated August 9, 2011; Exhibit 11). This full report provided results of sediment sampling and chemical testing of sediments (mostly fine to medium sand of recent depositional origin) in conjunction with proposed maintenance dredging. The Sediment Sampling and Analytical Results Report concludes that based on Analytical Testing Data and Screening Level comparisons, sediments proposed to be dredged at the project site were found to be suitable for open -water disposal. The project goal is to mitigate sediment deposition in 2017 and restore navigational access at Lake Houses at Eagle Cove. The applicant is proposing to dredge from deeper water to more shallow water and is proposing to leave an approximately 4 to 6 feet Compliant if wide shelf from the northern property line of Lot A which would not be dredged. This area is being set aside for environmental enhancement/mitigation to provide a base to conditions install root wads (Exhibit 8). Environmental Enhancement and mitigation measures for are met the proposed project, arise from existing state and federal permitting requirements to improve near -shore shallow water habitat work through the various shoreline permits, including USACE Permit Reference #NWS-2007-1019 (Exhibit 3), Lake Washington/May Creek Dredging DNS-M, LUA05-138, SP, ECF (Exhibit 4) and Barbee Maintenance Dredging Mitigation Shoreline Exemption, LUA16-000388, SME (Exhibit 5). A few of the mitigation measures included, but were not limited to, the following: • Placement of 20 cubic yards of rounded river rock ("fish rock") along the rockery as well as several yards of fish rock adjacent to the boat ramp on Lot A to enhance the near shore shallow water habitat with more fish friendly materials; • Replacement of a 150 foot long solid wood float with a single 40 foot long grated float that maximizes light transmission to the shallow water habitat; • Replacement of three (3) failing creosote and rotted untreated wood piles securing the old float with two 10" galvanized steel pipe piles; and • Removal of woad and metal debris and rotting woad/leaf debris that depletes HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development SEDIMENT DEPOSITION MITiG, V Report of April 18, 2017 Nearing Examiner Recommendation LUA16-000977, ECF, SM Page 10 of 25 dissolved oxygen in the water column. Shoreline enhancement for near shore planting was completed in previous years, prior to 2011. It can be advantageous to allow the project to conduct one schedule for all levels of permitting for the subject project (i. e. Local, State, and Federal). As such, staff recommends as a condition of approval that the applicant submit copies of any and all permits and associated documents issued from other State and/or Federal permitting agencies to the Current Planning Project Manager. The applicant submitted a Lake Study prepared by Meridian Environmental, inc. (dated December 23, 2016) that included seven environmental protection and enhancement measures for the sediment deposition mitigation project. Staff recommended a SEPA mitigation measure that the applicant shall comply with the environmental protection and enhancement measures found in the Lake Study or updated report submitted at a later date. Therefore, if all conditions are complied with and mitigation is completed, the provided reports conclude that the project would not result in net loss of ecological functions and values. Policy SH-14: Shoreline use and development should be carried out in a manner that prevents or mitigates adverse impacts so that the resulting ecological condition does not become worse than the current condition. This means ensuring no net loss of ecological functions and processes in all development and use. Permitted uses should be designed and conducted to minimize, in so far as practical, any resultant damage to Compliant if the ecology and environment (RCW 90.58.020). Shoreline ecological functions that conditions should be protected include, but are not limited to, fish and wildlife habitat, food chain are met support, and water temperature maintenance. Shoreline processes that shall be protected include, but are not limited to, water flow; littoral drift; erosion and accretion; infiltration; ground water recharge and discharge; sediment delivery, transport, and storage; large woody debris recruitment; organic matter input; nutrient and pathogen removal; and stream channel formation/ maintenance. Staff Comment: See comments above under Policy SH-7. Objective SH-E: Existing economic uses and activities on the shorelines should be ,'r recognized and economic uses or activities that are water -oriented should be encouraged and supported. ✓ Policy SH-32: Water -oriented recreational activities should be encouraged. Policy SH-36: Subject to policies providing for no net loss of ecological functions as well as local, state, and federal regulations, the water's depth may be changed to foster recreational aspects. Staff Comment: The applicant stated that the purpose of the proposed dredging project is to dredge the least amount of depositional material possible to maintain Compliant if navigational and recreational access, not to restore historical lakebed elevations in conditions Lake Washington (Exhibit 6). While as the same time, demonstrate that the proposed modifications would result in no net loss, meaning the applicant must demonstrate are met that the modifications, combined with any mitigation efforts, would result in equivalent or better protection of shoreline functions. See also comments above under Policy SH-7. According to the Lake Study (Exhibit 13), the proposed project would involve amending the current Corps programmatic permit to allow dredging of up to an additional 4,000 cubic yards of sediment in an area located adjacent to the existing permitted dredge prism (Exhibit 6). Dredging to achieve the desired navigational depth profile would HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development SEDIMENT DEPOSITION MITIG, v Report of April 18, 2017 Hearing Examiner Recommendation LUA26-000977, ECF, SM Page it of 25 deepen the expanded dredge prism by approximately 10 feet (Exhibit 7).

DEVELOPMENT STANDARDS: The subject site is classified as Shoreline High Intensity on the City of Renton Shoreline Overlay Map. The following development standards are applicable to the proposal: 1. No Net Loss Required Shoreline use and development shall be carried out in a manner that prevents or mitigates adverse impacts to ensure no net loss of ecological functions and processes in all development and use. Permitted uses are designed and conducted to minimize, in so far as practical, any resultant damage to the ecology and environment (RCW 90.58.020). Shoreline ecological functions that shall be protected include, but are not limited to, fish and wildlife habitat, food chain support, and water temperature maintenance. Shoreline processes that shall be protected include, but are not limited to, water flow; erosion and accretion; infiltration; groundwater recharge and discharge; sediment delivery, transport, and storage; large woody debris recruitment; organic matter input; nutrient and pathogen removal; and stream channel formation/maintenance. Compliant if Staff Comment: According the Sediment Sampling and Analytical Results Report, the condition of parcels that have received the most depositional infrll sediments of fine to medium approval �5 sands with some gravel (identified as well draining fill material) in recent years were 3979 Lake Washington Blvd N (Lot A) and a major portion of 3909 Lake Washington mett Blvd N (Lot B). Finer sediments were identified as unsuitable for shallow water fish habitat enhancement along the rockery to the immediate south. 3907 Lake Washington Blvd N (Lot C) and 3905 Lake Washington Blvd N (Lot D) were not impacted to an extent that dredging would be required in 2017. Likewise, it is anticipated that 4011 Wells Ave N (boathouse property) would also nor require a lot of sediment removal in the near term. The applicant has indicated that the sediment deposition from the May Valley is a dynamic process and estimating future sediment loadings by parcel is not possible given the unknowns of weather, sediment deposition rates, deposition directions and locations, as well as estimating the effectiveness of proposed measures to mitigate deposition. The focus of the proposed dredging project is to mitigate sediment deposition and restore navigational access in the northern portion of the subject property.

Compliant if Staff Comment: According to the Biological Assessment, dredging of the May Creek conditions Delta and boathouse area has occurred for over 50 years on a 3- to 4-year cycle are met (Exhibit 12). Most recently, the area was dredged in 1994, 1997, 200112002 and 2011 due in part to high sediment loading, lack of large woody debris (LWD), loss of habitat complexity, forest removal, presence of rock quarries, and the expansion of road networks in the lower four (4) miles of May Creek watershed. The proposed HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development SEDIMENT DEPOSITION MITIG V Report of April 19, 2017 Wearing Examiner Recommendation LUA16-000977, ECF, SM Rage 19 of 25 maintenance dredging project is required to maintain and preserve navigational access to the boathouse, shared use dock, and recreational access. The applicant anticipates maintaining the same 3-5 year cycle with 2,500 to 4,000 cubic yards of sediment required to be removed from Lake Washington in order to preserve navigation access. The 2016 Lake Study included seven environmental protection and enhancement measures for the sediment deposition mitigation project. Staff recommends a SEPA mitigation measure that the applicant shall comply with the environmental protection and enhancement measures found in the Lake Study prepared by Meridian Environmental, inc. (dated December 23, 2016) or updated report submitted at a later date. iv. The responsibility rests solely with the applicant to demonstrate that: (a) There will be no net loss of ecological functions including but not limited to adverse effect on aquatic species including fish migration. Staff Comment: The project site is located and composed of aquatic lands in Lake Washington. The proposed dredging near May Creek in Lake Washington (no dredging would take place in May Creek). The Lake dredge would stir -up some sediment in the water but the sediments should settle out of the water fairly quickly after the dredging has been completed. According to the applicant, dredge work would require approximately 80 hours over a 10 day period. The applicant is proposing minimization techniques, such as lining the perimeter of the borge with hay bales wrapped with filter fabric to prevent dredge material from entering Lake Washington, where it could cause turbidity. Dredging would only be conducted during National Marine Fisheries Service (NMFS) approved July 16- September 15 work window by avoiding work during the rainy season. The project would avoid dredging along shoreline slopes and shallow water habitat along the shoreline north of the dredging zone to protect near -shore habitat that may be used by rearing Chinook salmon and enhance the north end of the project boundary through Compliant if the placement of Large Woody Debris (LWD) (approximately five to ten rootwods). conditions According to the applicant, the LWD would serve to improve aquatic habitat, help are met stabilize the shoreline, and facilitate sediment deposition to reduce the need for future maintenance dredging. The applicant submitted a Lake Study prepared by Meridian Environmental, Inc. (dated December 23, 2016, Exhibit 13) which concludes that the proposed project would unlikely hove an adverse effect on adult salmon and steelhead spawning habitat, as no dredging would take place in May Creek. The proposed project may affect juvenile salmon and steelhead by causing physical changes to their early rearing habitat in Lake Washington. Limiting the in -water work to the NMFS work window would minimize the potential to adversely affect juvenile Chinook, coho and steelhead, as the vast majority of juveniles in Lake Washington are expected to migrate prior to July. The dredging work proposed by the applicant is also subject to the U. S. Army Corps of Engineer (USACE) Permit Reference #NWS-2007-1019 conditions of approval (Exhibit 3) and the Barbee Maintenance Dredging Mitigation Shoreline Exemption permit condition of approval (Exhibit 5). The applicant submitted a Biological Assessment prepared by Meridian Environmental, inc. (dated August 27, 2012; Exhibit 12) which included nine conservation measures that the applicant would implement to avoid or minimize take of listed species and avoid or reduce impact to their habitat. Staff recommended, as a SEPA mitigation HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development SEDIMENT DEPOSITION MITIG, 'V Report of April 18, 2017 Hearing Examiner Recommendation LUA16-000977, ECF, SM Page 20 of 25 measure, that dredge project be required to comply with the conservation measures found in the Biological Assessment prepared by Meridian Environmental, Inc. (dated August 27, 2012). See also Environmental Review Committee Report (Exhibit 1) and decision (Exhibit 22) for more information. Therefore, the project is not anticipated to result in permanent impacts to fish migration. (b) There will be no adverse impact on recreational areas or public recreation enjoyment of the water. Staff Comment. The proposed dredging project would not change public access or displace any existing recreational uses. The proposal would not significantly impact recreation opportunities, in port because any effects would be temporary; therefore, no measures to reduce or control impacts on recreation are proposed. See also comments above under policy SH-7. v. Adjacent Bank Protection: (a) When dredging bottom material of a body of water, the banks shall not be disturbed unless absolutely necessary. The responsibility rests with the applicant to propose and carry out practices to protect the banks. Staff Comment: The applicant is proposing to dredge from deeper water to more shallow water using barge mounted equipment. At no time would dredging occur from the land. (b) If it is absolutely necessary to disturb the adjacent banks for access to the dredging area, the responsibility rests with the applicant to propose and carry out a method of restoration of the disturbed area to a condition minimizing erosion and siltation. Stoff Comment: See staff comment above. vi. Avoidance of Adverse Effects: The responsibility rests with the applicant to demonstrate the proposed dredging will avoid conditions that may adversely affect adjacent properties including: (a) Creating a nuisance to the public or nearby activity. Staff Comment: Overall, the dredge project would be temporary in nature, with construction being conducted during National Marine Fisheries Service (NMFS) approved July 16-September 15 fish window when fish passage facilities are not run. The applicant has indicated that work would occur during daylight hours; generally from 7 am to 7 pm. All construction must adhere to working hours as specified in Renton Municipal Code (RMC) and if haul routes are required they would be restricted to arterial streets. Due to the limited duration of the dredging events, the construction noises are not anticipated to adversely affect adjacent properties. (b) Damaging property in or near the area. Staff Comment: The project has been designed by a professional engineer and it is not anticipated that the dredging would result in any damage to property in or near the area. (c) Causing substantial adverse effect to plant, animal, aquatic or human life in or near the area. Staff Comment: See responses in Review Criteria: iv.a and vi.a.

Staff Comment: The project is not anticipated to endanger public safety in or near the area. vii. The applicant shall demonstrate control of contamination and pollution to water, air, and ground through specific operation and mitigation plans. Staff Comment: The Sediment Report (Exhibit 9) found that the detected chemical contamination in the permitted dredge area to be very limited or below Dredge Material Management Program (DMMP) fresh water and marine screening levels. The results of the report indicated some motor oil range petroleum hydrocarbon detected at 39 mg/kg (dry basis), diesel range petroleum product detected in the composite sample at 8.3 mg/kg (dry basis), and traces of Polynuclear Aromatic Hydrocarbons (PAHs). For example, benro(a)pyrene was detected at 14 ug/Kg (dry basis). The Sediment Sampling and Analytical Results Report concludes that based on Analytical Testing Data and Screening Level comparisons, sediments proposed to be dredged at the project site were found to be suitable for open -water disposal. The applicant has indicated that equipment used in the dredging project would be tuned and well maintained prior to construction activity. If at any time the equipment is not operating properly and needs maintenance, equipment would be taken out of service until repairs are completed and emissions ore within acceptable operating criteria. Most contractors have switched from petroleum based hydraulic fluid to vegetable based materials, particularly peanut oil. viii. Disposal of Dredge Material: The applicant shall demonstrate that the disposal of dredged material will not result in net loss of ecological functions or adverse impacts to properties adjacent to the disposal site. (a) The applicant shall provide plans for the location and method of disposing of all dredged material. Staff Comment: The applicant has specified that the disposal of the excavated sediment would be transported one of three ways: hauled off -site, off-loaded at a site on take Washington, or open water/ocean disposal. if either of the first two ways ore selected for handling sediments, a detailed Traffic Control Plan would need to be submitted and approved by the City of Renton prior to the start of construction. It would be the applicant's responsibility to identify a suitable disposal location to ensure that the compliant if disposal site is permitted and compliant with any necessary regulations. Furthermore, if conditions hauling off site resulted in any shoreline bank impacts mitigation would require for are met restoration of the shoreline bank. As such, staff recommends as a condition of approval that the applicant submit a restoration plan if off -site hauling results in any shoreline bank impacts. The plan shall be reviewed and approved by the Current Planning Project Manager prior to construction permit approval. (b) Dredged material shall not be deposited in a lake, stream, or marine water except if approved as habitat enhancement or other beneficial environmental mitigation as part of ecological restoration, a contamination remediation project approved by appropriate State and/or Federal agencies, or is approved in accordance with the Puget Sound Dredged Disposal Analysis evaluation procedures for managing in -water -disposal of dredged material by applicable agencies, which may include the U.S. Army Corps of Engineers pursuant to Section 10 (Rivers and Harbors Act) and Section 404 (Clean Water Act) permits, and Washington State HEX Report Sediment Deposition Mitigation City of Renton Department of Community & Economic Development Nearing Examiner Recommendation SEDIMENT DEPOSITION MITIG, v LUA15-000477, ECF, SM Report of April 18, 2017 Page 22 of 25 Department of Fish and Wildlife hydraulic project approval. Staff Comment: The applicant has indicated that ocean disposal is an option for receiving clean sediments from the project site at the Puget Sound Open Disposal site. Additional sediment sampling may be necessary to meet USACE requirements for ocean disposal. (c) In no instance shall dredged material be stockpiled in a shoreland area that would result in the clearing of native vegetation. Temporary stockpiling of dredged material is limited to one hundred eighty (180) days. Staff Comment: The applicant has identified Quendall Terminals (QT) as a potential receiving site. QT is 21.46 acres superfund site that is zoned Commercial/Office/ Residential (COR) and located within the Urban Shoreline designation under review to construct a mixed use development. The temporary stockpiling of sediment would not result in the clearing of native vegetation above what has already been considered as part of the Quendall Terminals Final Environment Impact Statement (LUA09-151). If this site is utilized approval shall be obtained from the Environmental Protection Agency (EPA) as it is designated a Superfund Site and the location shall not be located within 100 feet of the shoreline or within any existing wetland or buffer areas identified on the site. (d) If the dredged material is contaminant or pollutant in nature, the applicant shall propose and carry out a method of disposal that complies with all regulatory requirements. Staff Comment: See comments above under Review Criteria: viii. (e) Permanent land disposal shall demonstrate that: (1) Shoreline ecological functions will be preserved, including protection of surface water and groundwater. (2) Erosion, sedimentation, flood waters or runoff will not increase adverse impacts to shoreline ecological functions or property. (3) Sites will be adequately screened from view of local residents or passersby on public rights -of -way. (4) The site is not located within a channel migration zone. Staff Comment: See responses above under Review Criteria: iii and viii. 23. Consistency with Special Grade and Fill Permit: In order to grant a special permit, the Hearing Examiner shall make a determination that the activity would not be unreasonably detrimental to the surrounding area. As outlined in RMC 4-9-080F.4.a, The Hearing Examiner shall consider, but not be limited to, the following: Special Grade and Fill Permit Analysis a) Size and Location of the Activity Staff Comment: The applicant is seeking approval of a Special Fill and Grade Permit to rCompllance allow the dredging of sediment near the May Creek Delta.

Based on current bathymetry, the applicant is proposing to dredge approximately Z500 to 4,000 cubic yards of sediment during each dredging event (Exhibit 7). Sediment would be removed from Lake Washington using low impact machinery operated from a barge. The applicant is proposing minimization techniques, such as lining the perimeter of the barge with hay bales wrapped with filter fabric to prevent dredge material from entering Lake Washington, where it could cause turbidity. For disposal of dredge material information, see Shoreline Substantial Development Permit FOF 22. b) Traffic volume and patterns ✓ Staff Comment: The proposed project would not generate any additional vehicular traffic volumes. c) Screening, landscaping, fencing and setbacks Staff Comment: No screening, landscaping, fencing or setbacks are required in the City of Renton Development Standards for the dredging of May Creek. There are no plants within the proposed dredge area (not counting aquatic plants, principally milfoil) that would be disturbed by the work. The presence of aquatic plants is discussed in Biological Vol Assessments prepared by Meridian Environmental (particularly in 2010 and 2012; Exhibit 12). According to the report, Mllfoil has limited native aquatic plant development for the most part. No upland vegetation would be removed or altered at the project site at the Lake Houses. All work would occur in -water and uplands would not be impacted except for potentially stockpiling material for a limit number of years. d) Unsightliness, noise and dust Vol Staff Comment: See Community Disturbances under FOF 22, Shoreline Substantial Development Permit. e) Surface drainage ✓ Staff Comment: There would be no unpermitted runoff, including stormwater at the project dredge area.

The NOA describes an every 3 5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year; however, there is no information for phase 2 and how the 10 year request was derived_ 2. More information is needed regarding the full extent of dredging. The checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The project's purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel; the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bed) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. 3. It is our understanding that a 10 year dredging permit was issued and modified for parcel 0518501150 (Cuigini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. As part of the Notice of Application, City staff indicated that the dredging work may inadvertently spill over onto the May Creek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in Lake Washington. Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specifically stated that the dredging a 10,000 square foot area by 2 feet every 3 5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creek delta parcel to the north are included in this dredging proposal, the applicant should provide the following: a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented_ An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; b. A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown; and c. The location and success of previous mitigation measures for the previously permitted dredging work. 5. Also parcel 3342700009 (3907 Lake Washington Blvd N) currently does not have a dock or any structure that provides moorage_ Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of important shallow water habitat far juvenile salmon as the moorage needs can be accommodated by other means (i.e. expansion of existing joint moorage facilities, buoys, etc.). 6. Please provide additional information regarding the necessary navigational depth profile for each parcel. This information should be presented parcel by parcel in a table. 7_ Please provide monitoring data from previous dredging work. It is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. 8. One document that was sent via email with the Notice of Application is the Biological Assessment dated August 27, 2012 is for the dredging at the Boathouse parcel (0518501150); the parcel immediately south 3342700005 (3979 Lake Washington Blvd N); and a portion of parcel 3342700007 (3909 Lake Washington Blvd N). It does not cover dredging at the other parcels noted in the master land use application or NOA. Please indicate the control mechanism to avoid any spill over onto the May Creek Delta parcel (APN 0518600000) and why dredging work of parcels 3342700009 (3907 Lake Washington Blvd N) and 3342700011 (3905 Lake Washington Blvd N) were included in the proposal. 9. The assessment regarding potential salmon impacts as described in the 2012 Biological Assessment is based on limited information (i.e. Tabor at al 2004). Much more research data and information has been collected since this and should be used in a revised Biological Assessment or another environmental assessment format.

Please provide additional discussion and figures showing where and what mitigation was required and completed from the previous dredging permits. 11. The Sediment Sampling and Analytical Results report. From a quick review, the report is missing Attachments C and D, most importantly the actual sediment sampling results from Analytical Resources Inc.

Contact'Clark Close [425W4304289 ccldse@rent6nym.gow 1. What is the total duration of this dredging proposal? The NOA describes an every 3 5 year frequency but does not indicate the total number of years. The checklist notes a 10 year permit to be conducted over two phases. It appears that phase 1 is a single year: however, there is no information for phase 2 and how the 10 year request was derived. 2, More information is needed regarding the full extent of dredging- The checklist describes dredging 2,500 to 4,000 cubic yards at the boathouse, boat ramp, and support recreational uses in the project area. The projears purpose and areas of proposed needs must be substantiated. The applicant needs to clarify the exact areas to be dredged by parcel number; the amount to be dredged in each area of each parcel: the specific need for dredging in each area of each parcel. This information should be shown in both a table format and revised drawings (including existing topography prior to dredging and final proposed topography after dredging of the lake bad) that are sufficiently scaled and labeled. The drawings submitted with the application lacks sufficient detail to make these determinations. 3. It is our understanding that a 10 year dredging permit was issued and modified for parcel 0518501150 (Culgini Boathouse) was already issued by the City, the Corps, WDFW, and Ecology so the inclusion of this parcel for this project is unclear. Please explain why this parcel needs to be included with this project and how this proposal modifies the previous permitted dredging. 4. As part of the Notice of Application, City staff indicated that the dredging work may inadvertently spill over onto the May Greek Delta parcel (APN 0518500000), which includes the May Creek delta, due to the close proximity of the dredging work and lack of any survey monuments in Lake Washington. Previous environmental materials, including the Biological Assessment completed for the Barbee Mill Boathouse dredge dated July 11, 2007 specifically stated that the dredging a 10,000 square foot area by 2 feet every 3 5 years with some variation due to sediment deposition rates was the minimum necessary for the project's purpose. This was proposed as a Chinook salmon conservation measure along with other actions. Since this time, the boathouse parcel, 0518501150, requested a Corps permit to expand the dredge area by an additional 14,000 square feet without clear documentation that the initial sedimentation deposition rates had exceeded those anticipated with the smaller dredge foot print. Before either the boathouse or the May Creak delta parcel to the north are included in this dredging proposal, the applicant should provide the following: a. Complete documentation that all previous fish habitat conservation measures required under the previous dredging permits have been fully implemented. An initial list of these measures is available in the 2007 BA and the 2012 BA for the expanded dredge at the boathouse; b. A new bathymetry study to show that previous dredging was completed as permitted to depths and areas as shown: and c. The location and success of previous Mitigation measures for the previously permitted dredging work. 5. Also parcel 3342700009 (3907 Lake Washington Blvd N) currently does not have a dock or any structure that provides moorage. Therefore, why this parcel needs to be dredged is not apparent. Future undefined moorage needs are not a reason to allow dredging of important shallow water habitat for juvenile salmon as the moorage needs can be accommodated by other means (i.e. expansion of existing joint moorage facilities, buoys, etc.). 6. Please provide additional information regarding the necessary navigational depth profile for each parcel. This information should be presented parcel by parcel in a table- 7. Please provide monitoring data from previous dredging work. It is important to see if previous dredging work complied with Clean Water Act requirements and needs of salmon. 8. One document that was sent via email with the Notice of Application is the Biological Assessment dated August 27, 2012 is for the dredging at the Boathouse parcel (0518501150); the parcel immediately south 3342700005 (3979 Lake Washington Blvd N); and a portion of parcel 3342700007 (3909 Lake Washington Blvd N). It does not cover dredging at the other parcels noted in the master land use application or NOA. Please indicate the control mechanism to avoid any spill over onto the May Creek Delta parcel (APN 0518500000) and why dredging work of parcels 3342700009 (3907 Lake Washington Blvd N) and 3342700011 (3905 Lake Washington Blvd N) were included in the proposal. 9.

Please see items of concern/questions regarding Cugini Proposal to Stockpile Soil at Quendall Terminal Site - Who will monitor the noise? - What will be the vibration and noise decibel sound limits? - Noise and vibration limits may need to be adjusted to meet community needs. - How will vibration affect the homes along the property lines during construction? Which homes will be monitored for structural cracks and settlement from vibration? - How much setback from the property lines of existing homes for start of sediment stockpile? Should be made known to owners but shouldn't come up against fence line separating properties. {Note: The property line is not the same as where the fence is located. It extends beyond the fenceline.) Wood rot will occur on the north side of the fence if soil is piled up against fence. Also, for aesthetic reasons, Barbee Mill residents are requesting that stockpile not exceed middle of fence in height. Will stockpile be covered with plastic sheeting per regulation? - Please provide City of Renton contacts during construction and on site construction inspector for EPA. Work hours should be the same as in Seattle 7:00 AM — 6:00 PM; Saturday work should be eliminated. Construction access should have a wheel wash at exit point. How will contaminated soil track out be controlled during temporary sediment stockpile placement? Entry and exit should not be at N42nd PL where Barbee Mill residents exit to Lake Washington Blvd. - What has EPA proposed as a preferred cleanup, and what will be done to mitigate the effect on Barbee Mill Community? I was informed earlier that no one could enter the site without proper HAZMAT Personal Protective Equipment (PPE). Does this still apply for temporary stockpile? - Has the Feasibility Study been approved by EPA? Please provide their comments/ recommendations. I will await your responses to my questions.

Close, Senior Planner SUBJECT: Eagle Core Dredging General: We have completed a preliminary review of the pre -application for the above - referenced development proposal. The following comments on development and permitting issues are based on the pre -application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision -makers (e.g., Hearing Examiner, Community & Economic Development Administrator, Public Works Administrator, Planning Director, Development Services Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant.

The Development Regulations are available for purchase for $50.00 plus tax from the Finance Division on the first floor of City Hall or online at www.rentonwa.gov. Project Proposal: Eagle Cove Aquatic Land Management is proposing to continue periodic dredging of Lake Washington near the May Creek Delta as a result of soil and sediment accumulation at the Lake Houses at Eagle Cove ("Project Site"). The project site is located immediately south of the May Creek Delta from 3905-3979 Lake Washington Blvd N, including the boat house parcel. Soils and sediments at the project site are principally fine to medium sands with some gravels arising from erosion in the May Valley which causes substantial deposition in Lake Washington at the mouth of May Creek. Dredging of Lake Washington is being requested every 3 to 5 years to preserve navigational access to the docks, boathouse and recreational access for swimming, boating, canoeing, and water sports. The amount of sediment deposition has been described as increasing over the years from 3,000 to 4,000 CY every 3 to four years throughout the 1990's to 4,000 to 6,000 CY per year at the present. Periodic dredging could entail as much as 4,000 to 8,000 CY every 3 to 4 years. All work would be conducted below the Ordinary High Water Line. No additional fill is anticipated, except as previously approved in a Shoreline Exemption granted by the City of Renton (May 27, 2016). Approximately 20 CY of "fish rock" would be placed along the rockery to enhance shallow water habitat. Current Use: The property site includes four (4) single family parcels (334270-0005, -0007, -0009, and -0011) and one boathouse parcel (0518501150), The existing shoreline is largely built up and hardened with a rockery to protect the lots from shoreline erosion. Zoning: The residential properties are located within the Residential Medium Density (RMD) land use designation and the Residential-6 (R-6) zoning designation. The boathouse is located H:\CED\PIanning\Current Plannin&REAPP5\15-000170 Eagle Cove Dredging, PRE16-000617 Page 2 of 4 September 8, 2016 within the Residential High Density (RHD) land use designation and the Residential-10 (R-10) zoning designation. Development Standards: The project would be subject to RMC 4-2-110A, "Development Standards for Residential Zoning Designations" effective at the time of complete application. In addition, the project would also be subject to the City of Renton's Shoreline Master Program (SMP), such as RMC 4-3-090, "Shoreline Master Program Regulations," and RMC 4-9-190, "Shoreline Permits" because the subject project is located within Lake Washington. Many of the R-6 and R-10 development standards would not be applicable because of the nature of the subject project. As such, the following report only addresses the applicable development standards and/or shoreline regulations. Shoreline Regulations: The project area is in the May Creek Reaches (MC -A) near the May Creek Delta within Lake Washington. The project area has a shoreline designation of Shoreline High Intensity. Dredging shall not be performed within the delta of May Creek except for purposes of ecological restoration, for public flood control projects, for water -dependent public facilities, or for limited maintenance dredging in conformance with RMC 4-3-090F.3.c. Dredging may be permitted only in cases where the proposal, including any necessary mitigation, would result in no net loss of shoreline ecological functions and is limited to maintenance dredging for access to existing legally established boat moorage slips including public and commercial moorage and moorage accessory to single family residences; provided, that dredging shall be limited to maintaining the previously dredged and/or existing authorized location, depth, and width. Dredging shall be disallowed to maintain depths of existing private moorage where it results in a net loss of ecological functions. The subject project would result in impacts to Lake Washington and the May Creek Delta, as such a Biological Assessment was completed for the Cugini Property Boathouse Expansion of the Existing take Washington Dredge Prism. A Lake Study containing the information specified in RMC Section 4-8-120D would be required to be submitted with the Shoreline Substantial Development Permit. Regulations on Permitted Dredging, RMC 4-3-090F.3.d Review Criteria: The applicant is responsible to ensure that the following regulations are compiled with before and during a permitted dredging operation; ii_ All proposed dredging operations shall be designed by an appropriate State -licensed professional engineer. A stamped engineering report and an assessment of potential impacts on ecological functions shall be prepared by qualified consultants and shall be submitted to the Renton Planning Division as part of the application for a shoreline permit. iii. The responsibility rests solely with the applicant to demonstrate the necessity of the proposed dredging operation. iv. The responsibility rests solely with the applicant to demonstrate that: (a) There will be no net loss of ecological functions including but not limited to adverse effect on aquatic species including fish migration. (b) There will be no adverse impact on recreational areas or public recreation enjoyment of the water. v. Adjacent Bank Protection: (a) When dredging bottom material of a body of water, the banks shall not be disturbed unless absolutely necessary. The responsibility rests with the applicant to propose and carry out practices to protect the banks. HACED\Planning\Current Planning\PREAPPS\16-000617 Eagle Cove Dredging, PRE16-000617 Page 3of4 September 8, 2016 (b) If it is absolutely necessary to disturb the adjacent banks for access to the dredging area, the responsibility rests with the applicant to propose and carry out a method of restoration of the disturbed area to a condition minimizing erosion and siltation. vi. Avoidance of Adverse Effects: The responsibility rests with the applicant to demonstrate the proposed dredging will avoid conditions that may adversely affect adjacent properties including: (a) Creating a nuisance to the public or nearby activity. (b) Damaging property in or near the area. (c) Causing substantial adverse effect to plant, animal, aquatic or human life in or near the a rea. (d) Endangering public safety in or near the area. vii. The applicant shall demonstrate control of contamination and pollution to water, air, and ground through specific operation and mitigation plans. viii. Disposal of Dredge Material: The applicant shall demonstrate that the disposal of dredged material will not result in net loss of ecological functions or adverse impacts to properties adjacent to the disposal site. (a) The applicant shall provide plans for the location and method of disposing of all dredged material. (b) Dredged material shall not be deposited in a lake, stream, or marine water except if approved as habitat enhancement or other beneficial environmental mitigation as part of ecological restoration, a contamination remediation project approved by appropriate State and/or Federal agencies, or is approved in accordance with the Puget Sound Dredged Disposal Analysis evaluation procedures for managing in -water -disposal of dredged material by applicable agencies, which may include the U.S. Army Corps of Engineers pursuant to Section 10 (Rivers and Harbors Act) and Section 404 (Clean Water Act) permits, and Washington State Department of Fish and Wildlife hydraulic project approval. (c) In no instance shall dredged material be stockpiled in a shoreland area that would result in the clearing of native_ vegetation. Temporary stockpiling of dredged material is limited to one hundred eighty (180) days. (d) If the dredged material is contaminant or pollutant in nature, the applicant shall propose and carry out a method of disposal that complies with all regulatory requirements. (e) Permanent land disposal shall demonstrate that: (1) Shoreline ecological functions will be preserved, including protection of surface water and groundwater. (2) Erosion, sedimentation, flood waters or runoff will not increase adverse impacts to shoreline ecological functions or property. (3) Sites will be adequately screened from view of local residents or passersby on public rights -of -way. (4) The site is not located within a channel migration zone. Additional Notes to the Applicant: Dredging shall require a shoreline conditional use unless associated with existing water -dependent uses, habitat enhancement, a remedial action plan H:\CED\Planning\Current Planning\PREAP PS\16-000617 Eagle Cove Dredging, PRE16-000617 Page 4 of 4 September 8, 2016 approved under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or the Model Toxics Control Act, or public recreation facilities or uses. For excavation or grading in excess of five hundred (500) cubic yards, the Hearing Examiner shall review, approve, disapprove, or approve with conditions the location of the site and its effect on the surrounding area via a Hearing Examiner Special Fill and Grade Permit after a public hearing per RMC 4-9-080, Environmental Review: The subject project is subject. to Washington State Environmental Policy Act (SEPA) because it is located in lands covered by water. Therefore, an environmental checklist is a submittal requirement. An environmental determination will be made by the Renton Environmental Review Committee. This determination is subject to appeal by either the project proponent, by a citizen of the community, or another entity having standing for an appeal. Permit Requirements: A Hearing Examiner Special Fill and Grade Permit and a Shoreline Substantial Development Permit (SSDP) shall be required. The proposal would also require Environmental 'SEPA' Review. All applications can be reviewed concurrently in an estimated time frame of 12 weeks with an additional 21-day appeal period for the SSDP with the Washington State Department of Ecology once a complete application is accepted. The 2016 Hearing Examiner Special Fill and Grade Permit application fee is $2,500, the Shoreline Substantial Permit application fee is $2,000, and the SEPA Review (Environmental Checklist) application fee is $1,000. There is an additional 3% technology fee at the time of land use application. Detailed information regarding the land use application submittal is available on the City of Renton website for your review.

Michael Lloyd Lloyd & Associates, Inc. 255 Camaloch Drive Camano Island, WA 98065 425-785-1357 Item 5 — Environmental Checklist 5-1 Sediment Deposition Mitigation T Lake Homes at Eagle Cove 5.4 Date checklist prepared: Checklist Revised December I. 2016 5.5 Agency requesting checklist: City of Renton, Department of Community and Economic Development 5.6 Proposed timing or schedule (including phasing, if applicable): Working in Lake Washington is subject to environmental restrictions to protect fisheries. Currently, dredging can only be conducted yearly between July 16 and September 15 through 2026. The current HPA allows for in -water work yearly from July 16 to December 31, 2021. As we understand the conflict in dates, dredging or placement of materials are subject to the smaller work window while environmental enhancement work could potentially be allowed from July 161h through December, 31 st. We are requesting a 10 year permit from the City of Renton to allow in -water work to be conducted in 2 Phases. The first phase would include dredging and mitigation/ environment enhancement work in the summer of 2017. The timing of the second phase {dredging} will be determined by the effectiveness of sediment mitigation measures, weather, and the vagaries of sediment deposition in the project area. As has been stated in the past permit applications, the major problem is continued deposition of sediments eroded in the May Creek Drainage Basin that are delivered to Lake Washington during severe storm events. Until such time that meaningful measures are implemented to reduce erosion or deal with the impacts substantial sediment deposition, dredging will be necessary to mitigate the impacts of uncontrolled erosion in the May Valley and the downstream impacts of sediment deposition. Dredging is estimated to be required every 3-5 years, although the frequency is completely dictated by extreme weather conditions and the severity of storm water flows in May Creek that result in sediment deposition. Although estimates, based on predicting the weather are limited, approximately 2,500 to 4,000 CY of sediment will be dredged during each dredging event to maintain access to the water at the boathouse, boat ramp, and support recreational uses throughout the project area. 5.7 Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? Ifyes, explain/ No. Nevertheless the applicant will eventually apply to the U. S. Army Corps of Engineers in the future for an amendment to their existing permit to allow for more comprehensive management of aquatic land throughout the project area of Eagle Cove, This future permitting action will reconcile differences between the permits and consider future dredging events throughout the Eagle Cove project area. 5.8 List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Item 5 — Environmental Checklist 5-2 Sediment Deposition Mitigation — hake Homes at Eagle Cove There is a long history of dredging and environmental enhancement in Lake Washington at the project site, preceding this application. Much of this information has been summarized by Meridian Environmental in their Biological Assessment prepared for the U. S. Army Corps of Engineer (USACE, 2012). This Biological Assessment was reviewed by and concurred with by the National Marine Fisheries Service (NMFS) and the USACE in 2014, the effective date of the Biological Assessment. A copy of the Biological Assessment was submitted with our pre -application to the City of Renton. Biological Assessments have been previously prepared in the project area dating back to 1994. 5.9 Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. At this time there are no other applications pending for governmental approvals or other proposals directly affecting this project. However, the project proponents will eventually seek to have federal permits in closer concurrence with state and local permits. Currently federal permits are focused on the north end of the project site. This focus will likely change as the May Creek Delta continues to expand at ever increasing rates with loss of habitat, increased impermeable surfaces, and stronger stormwater surges that are generated in the May Valley. 5.10 List any government approvals or permits that will be needed for your proposal, if'known. • Washington Department of Ecology Concurrence with Shoreline Permit from City of Renton) Water Quality Certification Washington Department of Fish and Wildlife Amendment of existing Hydraulic Project Approval * U.S. Army Corps of Engineers Amendment of existing USACE permit to reconcile differences (future amendment date, to be determined). 5.11 Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. Applicants seek to mitigate the impacts of uncontrolled sediment deposition in Lake Washington, arising from storm water surges in the May Creek Drainage Basin. As the May Creek Delta expands, access to the shorelines will become more limited. Currently, access to the boathouse is severely limited. As sediment deposition increases in the project area, use of the boathouse, boat ramp and shared use dock will be impacted along with other protected and unprotected recreational uses. Additionally, the use of a kayak float will be impacted as well. These recreational uses are dependent on access for use and enjoyment of the Lake Washington. Item 5 — Environmental Checklist s - 3 Sediment Deposition Mitigation — Lake Homes at Eagle Cove The project site is composed of five waterfront lots in Eagle Cove. The project site is approximately 91,000 sf within the inner harbor line of Lake Washington. While it is true that the majority of the dredging work will occur in the north end of the project area, the owners cannot take a limited short -time perspective on the problems of uncontrolled sedimentation impacts on the project area. Rates of sediment deposition will continue to increase in the project area with increasing impact(s) on the environment at Eagle Cove and ultimately northwards to the Barbee Mill Development, a residential community. 5.12 Location of the proposal, address, etc. 4001 Wells Avenue N. and residences at 370, 3909, 3907, and 3905 Lake Washington Boulevard, Renton, WA 98056 NW 32-2- 05 (47" 31' 38.85"N, 122° 12' 18.43"W) Vicinity Map and Legal descriptions (See Exhibit 1) B. ENVIRONMENTAL ELEMENTS 1. EARTH a. General description of the site The entire project site consists of near -shore aquatic lands within the Inner Harbor Line. Aquatic lands are owned by project proponent(s). No upland work is proposed in conjunction with this permit. h. What is the steepest slope on the site (approximate percent slope) ? The steepest slope is at the north end of the project area where the slope below the surface of Lake Washington is approximately is approximately 2:1 This slope was generated by sedimentation arising from erosion sources in the May Valley. c. What general types of soils are found on the site? Sediments in the project site (arising from May Creek depositional events) tend to be fine to medium sands (SP - MP) grading to gravels in closer proximity to May Creek. Sediments distal to May Creek trend to finer materials and some silt. Within the May Creek delta, larger rocks and gravels tends to predominate. For example, a recent severe storm event deposited a rounded rock approximately 12 inches long with a diameter of b inches, testifying to the power of stormwater flows scouring the May Creek Basin. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe No. There are no current indications of unstable soils in the proposed project area. However, upland soils at the shoreline are less stable. These unstable soil problems were resolved many years ago with the armoring of the shoreline immediately adjacent to the Item 5 — Environmental Checklist 5-4 Sediment Deposition Mitigation — Lake Homes at Eagle Cove project area. During armoring, aquatic lands were increased as the immediate shoreline was pulled back, when the basaltic rockery was constructed. e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. The purpose of this project is to maintain adequate navigational and shoreline access ay Eagle Cove. Currently, ignoring future depositional from May Creek, approximately 2,500 to 3,000 CY should be dredged to restore navigational access to the boathouse. This affects an area of approximately 25,000 sf at the north end of the project site, within the USACE permit prism. No filling is proposed as part of this dredging project, However, in mitigation for potential habitat impacts to the May Creek Delta, project proponents will place 20 CY of "fish rock" adjacent to the rockery to improve shallow water habitat and decrease the hardening impact of the rockery adjacent to Lots A to D. This aspect of the proposed work has been previously approved by the City of Renton in a Shoreline Exemption granted in 2016. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. No. The project will not involve clearing or any upland construction. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? None. There will be no impervious surfaces created before, during, or after construction. g. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: None. 2. AIR a. What types of emissions to the air would result from the proposal during construction= operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. Diesel exhaust emissions will result from operating heavy equipment during construction (dredging and environmental enhancement) work. Dredging equipment will operate approximately So hours over a 10 day period. Once construction work is complete, there will be no operations or maintenance emissions. b. Are there any off -site sources of emissions or odor that may affect your proposal? If 'so, generally describe. No. Item 5 — Environmental Checklist 5- 5 Sediment Deposition Mitigation — Lake Homes at Eagle Cove c. Proposed measures to reduce or control emissions or other impacts to air, if any: Equipment will be tuned and well maintained prior to construction activity. if at any time equipment is not operating properly and needs maintenance, equipment will be taken out of service until repairs are completed and emissions are within acceptable operating criteria. All operating equipment will not be idled when not in active use. 3. WATER a. Surface Water. 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? Ifyes, describe type and provide names. If appropriate,_ state what stream or river it flows into. The project site is located in Lake Washington, immediately south of the May Creek Delta. The entire project site is composed of aquatic lands in Lake Washington. May Creek is a year-round stream that flows into Lake Washington just north of the project site. May Creek, the May Creek Drainage Basin, and impacts on Lake Washington have been extensively investigated. Probably the best discourse on the subject was prepared by King County and the City of Renton (May Creek Drainage Basin Action Plan (2001). To a limited extent, flooding in the upper reaches of May Creek appears to have been abated by channelizing May Creek to minimize flooding. The consequence of this "action" (whether intentional or ignoring consequences) is to substantially increase the volume of storm water surge, causing an increase in erosion and sediment deposition in Lake Washington. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? Ifyes, please describe and attach available plans. The project will require work over Lake Washington. Barge -mounted dredges or a barge mounted excavator will operate over the aquatic lands within the project boundaries. As stated earlier, there are two major components to the work (1) Dredging approximately 2,500 CY of accumulated sediment, and (2) completing environmental enhancement / mitigation work. Environmental Enhancement work includes the following: • Placement of 20 CY "fish rock" along the rockery as well as several yards of fish rock adjacent to the boat ramp on Lot A • Replacement of a solid wood float with a grated float that maximizes light transmission. • Replacement of 3 treated wood piles securing the old float with two 10" galvanized pipe piles. • Extraction of two dolphins (consisting of three treated piles each), at the south end of the project site with a single 12" galvanized pipe pile at each location Item 5 — Environmental Checklist 5-6 Sediment Deposition Mitigation — Lake Homes at Eagle Cove 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Based on current bathymetry (hydrographic contours (pre -dredge 2016), approximately 2,500 CY of depositional sediments would be dredged. However, this estimate is subject to dramatic increase during the rainy season of Fall 2016 to Spring 2017. There is no wav to estimate the quantity of sediment from erosional processes in the May Creek Drainage basin, because predicting the weather and probable severe storm events is not a winning bet. It is entirely possible that there will be no increase in sediment deposition or that there could be a banner year of 10,000 CY to the May Creek Delta from the May Creek Drainage Basin. The percentage of depositional 'fill"that will be deposited in the navigational access channel to the boathouse and project site is completely unknown. Our most optimistic estimate is that in 2017 there will be approximately 2,500 of depositional infill to be dredged to maintain access, 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. 5) Does the proposal lie within a 100 year floodplain? If so, note location on the site plan. No. Lake Washington elevations are controlled by the U.S. Army Corps of Engineers (USACE). There is no 100-years tloodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground Water. 1) Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known No. 2) Impact on Groundwater. None. 3) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example. Domestic sewage; industrial, containing the Item 5 — Environmental Checklist 5-7 Sediment Deposition Mitigation — Lake Homes at Eagle Cove following chemicals. ; agricultural, etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material(s) will be discharged. c. Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. There will be no unpermitted runoff (including, storm water at the project dredge area.) In major part the response to this question is addressed in 3)(b)(1) proceeding. 2) Could waste materials enter ground or surface waters? If so, generally describe. No waste materials will be discharged to ground or surface waters. 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. No. The proposed work will not alter or otherwise affect drainage patterns in the vicinity of the site. This is unfortunate, since it would be great to solve sediments deposition problems in Lake Washington arising from uncontrolled erosion in the May Creek Drainage Basin (necessitating this proposal to mitigate the damages caused by upstream erosion arising in the (May Creek Drainage Basin). d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: Some return water from dredged materials, as placed on a barge, is anticipated. It is extremely import to understand that the dredged material is highly porous and drains very quickly during dredging as the bucket is raised out of the water. This return water is the subject of the Water Quality Certification approved by the Department of Ecology. Notably, there is very little silt or clay content in dredged materials as indicated in recent sediment testing. Essentially, the sediments are near "dry" as loaded onto the barge. The perimeter of the barge will be lined with hay bales wrapped with filter fabric to reduce potential turbidity in Lake Washington. This is not a theoretical exercise. Dredging was completed in 2011 following these protocols without problems of either excessive return water or exceeding water quality criteria. 4. PLANTS a. Check the types of vegetation found on the site: Item 5 — Environmental Checklist 5-8 Sediment Deposition Mitigation — Lake Homes at Eagle Cove There are no plants within the proposed dredge area (not counting aquatic plants, principally milfoil) that will be disturbed by the work. The presence of aquatic plants is discussed in Biological Assessments prepared by Meridian Environmental (particularly 2010, and 2012). In major part Milfoil has limited native aquatic plant development b. What kind and amount of vegetation will be removed or altered? None. No upland vegetation will be removed or altered at the project site at the Lake Houses. Milfoil in the aquatic environment will be temporarily disturbed. Unfortunately, milfoil will return in abundance. c. List threatened and endangered species known to be on or near the site. Listed salmon species, steelhead, bull trout, bald eagles, d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any. None. All work will be in -water, and uplands will not be impacted e. List all noxious weeds and invasive species known to be on or near the site. The most common and pervasive plant species is milfoil which is present throughout Lake Washington. 5. ANIMALS a. List any birds and other animals which have been observed on or near the site or are known to be on or near the site. Examples include; Birds: hawk, heron, eagle, songbirds, other: eagle,osprey. crows, water fowl, herons and Canadian Geese Mammals: deer, bear, elk, beaver, other: coyote. deer Fish: bass, salmon, trout, herring, shellfish, salmon, trout, bass, sunfish, crayfish and turtles. b. List any threatened and endangered species known to be on or near the site. Chinook salmon (Qncorhynchus tshawytscha) Steelhead (Oneorhynchus mykiss) Bull trout (Salvelinus confluentus Coho salmon (Qncorhynchus kasutch) e. Is the site part of a migration route? If so, explain. Yes, May Creek is a known spawning stream for fishes as long as anyone can remember. Migratory fowl are also known to stop over in Lake Washing in summers and winters Item 5 — Environmental Checklist 5-9 Sediment Deposition Mitigation — Lake homes at Eagle Cove d. Proposed measures to preserve or enhance wildlife, if any: A shoreline exemption was granted by the City of Renton for environmental enhancement work which includes the following major components: • Placement of 20 CY "fish rock" along the rockery, as well as, several yards of fish rock adjacent to the boat ramp on Lot A • Replacement of a solid wood float with a grated float that maximizes light transmission. • Replacement of 3 treated wood piles securing the old float with two 10" galvanized pipe piles. • Extraction of two dolphins (consisting of three treated piles each), at the south end of the project site, and replacing the dolphins with a single 12" galvanized pipe pile at each location In addition to environmental enhancement work previously permitted by the City of Renton, we are also proposing to enhance the north end of the project boundary adjacent to the May Creek Delta with placement of Large Woody Debris (LWD) that helps stabilize shorelines and provides vital habitat for salmon and other animals. Preserving and even increasing the amounts of large woody debris along shorelines is important for keeping our aquatic areas healthy and improving the survival of native salmon and other animals. A few of the benefits of LWD include: • It provides refuge for juvenile and adult fish at a wide range of river flows, such as flood events common to the May Creek Delta, • It creates pools for juvenile fish and hydraulic complexity and roughness along the creek bank, • It provides food sources and habitat for aquatic insects and wildlife along shorelines, and • It helps stabilize shorelines and reduce excessive erosion. An additional benefit of placing LWD at the edge of the May Creek delta is that root wads create an area of still water where sediments will drop out and potentially reduce deposition impacts in the project area. e. List any invasive animal species known to be on or near the site. Bass are potentially the major fish known to be at the project site. Bass are predators that feed on fry and other small fishes, 6. ENERGY AND NATURAL RESOURCES a. What kind.v of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. Item 5 — Environmental Checklist 5 - 10 Sediment Deposition Mitigation — Lake Homes at Eagle Cove No energy resources will be required to meet completed project's energy needs. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. No. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any None. There will be no energy consuming sources (see b. above) 7. ENVIRONMENTAL HEALTH a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste that could occur as a result of this proposal? If so, describe. The primary health or environmental exposure that could occur would be a spill of hydraulic fluid or other petroleum product during construction by dredging equipment. Most contractors have switched from petroleum based hydraulic fluid to vegetable based materials, particularly peanut oil. Sediments from the dredge area have been tested multiple times and are known to be clean materials resulting from sediment deposition by May Creek. The most recent sampling and analysis occurred in July, 2016. 1) Describe any known or possible contamination at the site from present or past uses. The major source of potential contamination arises from Quendall Terminals (a superfund site) approximately 2000 feet north of the project site. When tested, sediments at Eagle Cove were substantially below MTCA Residential Cleanup levels as well as open water disposal action levels. As a point of reference, detected levels of PAH compounds were below background levels for the Puget Sound region. There is another potential source of contamination that may contribute petroleum hydrocarbons. Working boom boats were often moored at the site of the Boathouse. This area was dredged in 2011 after sediment testing indicated that diesel and motor oil residues that were detected were substantially (orders of magnitude) below levels of concern. Recent sampling and analysis indicates the petroleum hydrocarbon residues are substantially below aquatic cleanup criteria. 2) Describe existing hazardous chemicals/conditions that might affect project development and design. This includes underground hazardous liquid and gas transmission pipelines located within the project area and in the vicinity. There are no existing hazardous chemicals and conditions that would affect the Item 5 — Environmental Checklist 5 - 11 Sediment Deposition Mitigation — Lake Homes at Eagle Cove proposed dredging. Indeed, sediments are acceptable for all beneficial uses upland without restriction. There are no gas lines within the project area although there is a natural gas line upland that serves the City of Renton. 3) Describe any toxic or hazardous chemicals that might be stored, used, or produced during the project's development or construction, or at any time during the operating life of the project. Hazardous chemicals or materials will not be stored, used, or produced during or after construction. Heavy equipment requires petroleum and vegetable oil (specifically for hydraulic systems) products to operate properly. These products may be become hazardous under special conditions ( fire, spill, etc) 4) Describe special emergency services that might be required. During construction (dredging in -water, environmental enhancement work), there is always the potential for a work place accident that may require medical emergency services. In the event of a spill of petroleum or other material spill, specialized cleanup services may be required. 5) Proposed measures to reduce or control environmental health hazards, if any: Prior to beginning construction on this project, a kickoff meeting will be held to review the overall project, detail specialized risks, and review emergency response measures with project team management and construction crew members. Representative from the City of Renton, USAGE and other regulatory/administrative personnel will be invited to attend. The purpose is to provide information, and respond to questions, and to be clarify potential risks, and to discuss means to mitigate known and unknown risks. During construction, daily health and safety meetings will be conducted with construction crews, to alert them to special risks that may be present during planned work efforts for the day. In addition to daily health and safety meetings, equipment will be inspected daily to minimize the potential for equipment failures which may contribute to environmental health hazards. The intent is to foster a work environment that is protective of workers and the environment. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? None. Item 5 — Environmental Checklist 5- 12 Sediment Deposition Mitigation — Fake Homes at Eagle Cove 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Operation of dredging equipment and upland heavy equipment (frontend loaders, etc) will generate expected noise levels during construction of up 80 to 90 decibels on a short-term basis only during construction. No long-term noise levels will be created. Construction noise will only occur during daylight hours between 7 AM and 7 PM, Monday through Saturday. No work will occur on Sunday. 3) Proposed measures to reduce or control noise impacts, if any: Noise impacts of heavy equipment operation will occur, but will be limited to the extent that equipment will be properly maintained and muffled to the extent possible such that noise levels may be reduced to the minimum. The short duration of work over Lake Washington will mean that noise impacts will be temporary. S. LAND AND SHORELINE USE a. What is the current use of the site and adjacent properties? Will the proposal affect current land uses on nearby or adjacent properties? If so, describe. As described in the Project Narrative, the current use of the site is for single family homes and a boathouse at the north end. This proposal will not affect current land uses, but will provide for the continued recreational and aesthetics enjoyment of waterfront living. Adjacent properties to the south are also single family homes. To the north is the Barbee Mill Development, a planned unit development. This proposal will not affect current land uses on nearby or adjacent properties. b. Has the project site been used as working farmlands or working forest lands? If so, describe. How much agricultural or forest land of long-term commercial significance will be converted to other uses as a result of the proposal, if any?

Approximately how many people would the completed project displace? None_ k. Proposed measures to avoid or reduce displacement impacts, if any: Not Applicable. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any. Item 5 — Environmental Checklist 5 - 14 Sediment Deposition Mitigation — Lake Homes at Eagle Cove A fundamental purpose for completion of this permit application/process and subsequent approval by the City of Renton, is to assure that the proposal is compatible with existing and projected land uses and plans. m. Proposed measures to ensure the proposal is compatible with nearby agricultural and forest lands of long-term commercial significance, if any: None. There are no nearby agricultural or forest lands of long-term commercial significance, 9. HOUSING a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low-income housing. None.. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing. None. c. Proposed measures to reduce or control housing impacts, if any: None. 10. AESTHETICS a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building materials) proposed? Not Applicable. No structures are proposed b. What views in the immediate vicinity would be altered or obstructed? None. No views would be altered or obstructed. c. Proposed measures to reduce or control aesthetic impacts, if any: None. There will be no aesthetic changes or impacts 11. LIGHT AND GLARE Item 5 — Environmental Checklist 5 - 15 Sediment Deposition Mitigation — Lake Homes at Eagle Cove a. What type of light or glare will the proposal produce? What time of day would it mainly occur? None. No changes are proposed that will change or alter light or glare. b. Could light or glare from the finished project be a safety hazard or interfere with views? No. c. What existing off -site sources of light or glare may affect your proposal? None. d. Proposed measures to reduce or control light and glare impacts, if any: None. 12. RECREA TION o. What designated and informal recreational opportunities are in the immediate vicinity? The purpose of the proposed dredging and environmental enhancement work is to encourage sustainability of both protected and informal recreational opportunities on Lake Washington at Eagle Cove. Project proponents seek to preserve access to the boathouse, shared -use dock, boat ramp, kayak float and amenities for boating, fishing, swimming and shoreline enjoyment unique to Lake Washington. The loss of these designated and informal recreational uses is not acceptable. b. Would the proposed project displace any existing recreational uses? If so, describe. No. The proposed project will help sustain and promote existing and future recreational uses. c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any: This entire project is promoted to reduce or to control impacts on recreational uses and to promote the use and enjoyment of Lake Washington. Nothing would serve this effort more than eliminating or controlling depositional impacts arising from erosion in the May Creek Drainage Basin. 13, HISTORIC AND CULTURAL PRESERVATION Item 5 — Environmental Checklist 5 - 16 Sediment Deposition Mitigation — Lake Homes at Eagle Cove a. Are there any buildings, structures, or sites, located on or near the site that are over 45 years old listed in or eligible for listing in national, state, or local preservation registers located on or near the site? If so, specifically describe. No. b. Are there any landmarks, features, or other evidence of Indian or historic use or occupation? This may include human burials or old cemeteries. Is there any material evidence, artifacts, or areas of cultural importance on or near the site? Please list any professional studies conducted at the site to identify such resources. To the extent that landmarks, features, or other evidence of Indian or historic use or occupation may have been present at one time. these features have been not been observed or simply covered with depositional sediments from May Creek . These changes include: • Lowering of Lake Washington during the construction of the Ballard Locks, • Reconfiguration and relocation of May Creek, (May Creek at one time entered Lake Washington at the Quendall Terminals site, north of the proiect site. • Development of shorelines in the City of Renton, and • Sediment deposition at the Shoreline of lake Washington. c. Describe the methods used to assess the potential impacts to cultural and historic resources on or near the project site. Examples include consultation with tribes and the department of archeology and historic preservation, archaeological surveys, historic maps, GIS data, etc. Methods to assess the potential impact of cultural and historic resources on or near the project site are limited by site development and changes noted in 13.b immediately preceding. To the best of site knowledge, going back at least 50+ years, dredging in the proposed project area will not encounter or impact any sediments except those of recent depositional origin (within the past 15 years). d. Proposed measures to avoid, minimize, or compensate for loss, changes to, and disturbance to resources. Please include plans for the above and any permits that may be required. Project plans for dredging will be limited to dredging accumulated sediment that has been deposited over the past 15 years since the May Creek Delta was last dredged. Because dredging will not reach the depths that may be of cultural or historical significance, this will avoid such impacts. 14. TRANSPORTA TION Item 5 — Environmental Checklist 5 - 17 Sediment Deposition Mitigation — Lake Homes at Eagle Cove a. Identify public streets and highways serving the site or affected geographic area and describe proposed access to the existing street system. Show on site plans, if any. The Lake Houses at Eagle Cove are served by access through the Barbee Mill Development. No changes are anticipated. Access is shown on the Vicinity Map. b. Is the site or affected geographic area currently served by public' transit? If so, generally describe. If not, what is the approximate distance to the nearest transit stop? Public transport is immediately available on Lake Washington Blvd. N. c. How many additional parking spaces would the completed projector non project proposal have? How many would the project or proposal eliminate? None. No additional parking or elimination of parking spaces is proposed. d Will the proposal require any new or improvements to existing roads, streets, pedestrian, bicycle or state transportation facilities, not including driveways? If so, generally describe (indicate whether public or private). No, e. Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. No. f. How many vehicular trips per day would be generated by the completed project or proposal? If known, indicate when peak volumes would occur and what percentage of the volume would he trucks (.such as commercial and non passenger vehicles). What data or transportation models were used to make these estimates? The completed project will not generate any additional vehicular trips per day. During construction on Lake Washington, workers will make trips to the project site. Adequate parking is available to accommodate this temporary increase in vehicular trips. g. Will the proposal interfere with, affect or be affected by the movement of agricultural and forest products on roads or streets in the urea? If so, generally describe. No. h. Proposed measures to reduce or control transportation impacts, ij'any: None proposed. Item 5 — Environmental Checklist 5 - 18 Sediment Deposition Mitigation — Lake Homes at Eagle Cove 15. PUBLIC SERVICES a. Would the project result in an increased need for public services (for example: fire protection, police protection, public transit, health care, schools, other)? If so, generally describe. No. b. Proposed measures to reduce or control direct impacts on public services, if any. None proposed. 16. UTILITIES a. Check or circle utilities currently available at the site: the following utilities are currently available to the Lake Houses at Eagle Cove • electricity, • natural gas, • water, • refuse service, • telephone, and • sanitary sewer b. Describe the utilities that are proposed for the project, the utility providing the service, and the general construction activities on the site or in the immediate vicinity which might be needed.. No utilities are proposed for the project. C. SIGNATURE The above answers are true and complete to the best of my knowledge.

Sediment Deposition Mitigation — The Lake Houses at Eagle Cove Project size: Approximately 91,000 sf Location: 4001 Williams Ave, and 3905, 3907, 3909 and 3979 Lake Washington Blvd. N, Renton, WA 98056 (see Neighborhood Detail/Vicinity Map). 6.2 Land use permits required for proposed project The Lake Houses at Eagle Cove homeowners are applying for "Special Permit" for Grade and Fill from the City of Renton to conduct Sediment Deposition Mitigation dredging. A Substantial Shoreline Development Permit from the City of Renton is required. The project proponents will also require concurrence with the Substantial Shoreline Development Permit by the Department of Ecology. Additional permits and approvals that will/may be required include: • Maintenance Dredging Permit Amendment — U.S. Army Corps of Engineers • Hydraulic Project Approval Amendment — Department of Fish and Wildlife • Water Quality Certification Amendment — Washington Department of Ecology 6.3 Existing and Projected Zoning Existing zoning is principally single family residential {R-10 at the Boathouse Lot, and R-6 at the four lots immediately adjacent and to the south. No changes in any zoning are proposed. 6.4 Current use of the site and any existing improvements Uplands at the project site in Lake Washington are residential, as described in 6.3 above. Uplands consist of a boathouse on the north end lot and four single family residences on the shoreline of Lake Washington, The Lake Houses at Eagle Cove are adjacent to aquatic lands owned by project proponents. A shared -use -dock at the southern end of the project area was constructed in 2006 serving the single family residences. In addition to the boathouse on the Project Narrative 5-1 Sediment Deposition Mitigation — Lake Houses at Eagle Cove north end, a boat ramp is located at lot A (see Title Report Summary). The boah ramp also provides lake access, serving protected recreational uses. 6.5 Special Site Features (i.e. wetlands, water bodies, steep slopes) The entire project site is located on aquatic lands within the Inner Harbor Line of Lake Washington. North of the project area is the May Creek Delta. May Creek and the May Creek Drainage Basin have been studied extensively in recent years. One of the best treatises' on May Creek and the May Creek Drainage Basin was prepared in 2001 by King County and the City of Renton. There are no steep slopes within the project area. One of the most fundamental special site features is the access to Lake Washington and the many protected and non -protected recreational uses. The major purpose of this project is to sustain these special features and recreational uses from uncontrolled erosion in the May Creek Drainage Basin which dumps eroded sediments into Lake Washington, as a consequence of development and habitat loss in May Valley. 6.6 Statement addressing soil type and drainage conditions Soils and sediments at the project site are principally fine to medium sands with some gravels arising from erosion in the May Valley resulting in substantial deposition in Lake Washington at the mouth of May Creek. Sediments are very porous and drain rapidly (like pouring water into a sandbox). Upland soils follow similar patterns with glacial sands and gravel outwash predominating. Drainage conditions at Eagle Cove uplands are good and the work in Lake Washington at the project site will not affect or otherwise impact upland drainages. 6.7 Proposed use of the property and scope of the proposed development Property uses will not change with the proposed project to sustain and preserve aquatic lands within the Inner Harbor Line. Rather, enhancement of the shoreline, maintenance of recreational access for swimming, boating, canoeing, and water sports are special recreational features of the upland properties at Eagle Cove. The purpose of the project is to maintain existing uses in the face of uncontrolled erosion in the May Creek Drainage Basin that results in substantial "unnatural" sediment deposition at the May Creek Delta and neighboring properties. 6.8 For plats indicate proposed number, net density and range of sizes of the new lots Not applicable. No plats are proposed 6.9 Access to the Property Gated and locked access is provided at the north end of the property from Wells Ave. Gated and locked access has also been provided to the City of Renton near the south end of the project site for utilities and emergency vehicles. Direct access to Lake Washington and the project site from the boat ramp on Lot A is another special feature serving the houses at Eagle Cove. 6.9 Proposed ofPsite improvements Project Narrative 5-2 Sediment Deposition Mitigation — Lake Houses at Eagle Cove No off -site improvements (utilities, access, etc) are proposed. All work will occur in the water at the project site from floating equipment. 6.10 Total estimated construction cost and estimated fair market value of the proposed project Estimated Costs are less than $300.000, not including substantial recurring permitting costs to mitigate uncontrolled sediment deposition. The fair market value of the existing properties will potentially decrease if the project is not completed and protected recreational uses and lake front amenities are further compromised by sediment deposition arising from uncontrolled erosion in the May Creek Drainage Basin. 6.11 Estimated quantities and type of materials involved if any fill or excavation is proposed No additional fill is anticipated, except as previously approved in a Shoreline Exemption granted by the City of Renton (May 27, 2016). A copy of the Shoreline Exemption is provided at the end of this section. Approximately 20 CY of "fish rock" (approved by the Washington State Department of Fish & Wildlife, U. S Army Corps of Engineers, and the City of Renton will be placed along the rockery to enhance shallow water habitat adjacent to the rockery. Dredging may be necessary every 3 to 5 years to preserve navigational access to the boathouse, recreational access and other water related uses. The rate of sediment deposition arising from May Creek, will dictate when dredging will be necessary, as well as, the quantity of material to be dredged. Throughout the 1990's May Creek deposited 3,000 to 4,000 CY ever 3 to 4 years. In recent years the amount of material being deposited in Lake Washington has substantially increased to a very roughly estimated at 4,000 to 6,000 CY per year. This is a substantial increase and a huge cause of concern for Eagle Cove residents. In time this will become a concern for the residents of the Barbee Mill Development as rising stream bed levels increase risk of flooding. Estimating future dredging requirements is difficult at best, since sediment deposition is entirely dependent on weather, continued degradation of the May Creek Drainage Basin, and the vagaries of nature. Nevertheless, future dredging could entail as much as 2,500 to 4,000 CY every 3 to 5 years. In major part we are proposing to dredge to a maximum profile to maintain access rather than a fixed quantity. This approach is consistent with USACE permit conditions and reflects the owner's intent to dredge as little as necessary. This is a costly venture. 6.12 Number, type and size of any trees to be removed None. 6.13 Explanation of any land to be dedicated to the City None, 6.14 Any proposed job shacks, sales trailers, and/or model homes Project Narrative 5-3 Sediment Deposition Mitigation — Lake Houses at Eagle Cove None. 6.15 Any proposed modifications heing requested (include written justification) for projects located within 100 feet of a stream or wetland? Dredging project will be located in Lake Washington and will include periodic dredging so as to maintain navigational access to the boathouse, shared use dock and protected recreational access to Lake Washington. Although there is not a current flood danger, as sediments continue to accumulate at the mouth of May Creek, the base elevation of May Creek will also rise. For example the Barbee Mill Development site was raised approximately 10 feet with fill to provide a measure of protection from flooding. At the same time, major portions of the May Creek Delta have risen as much at 20 feet. It is just a matter of time before the impacts of sediment deposition will be shared by many land owners near May Creek. All dredging work will be conducted below the Ordinary High Water Line. The Project is located adjacent to the ever expanding May Creek Delta. The expanding delta provides a particularly visual image of the consequences of uncontrolled erosion in the May Creek Drainage Basin. The existing shoreline is largely built up and hardened with a rockery to protect the Lake Houses at Eagle Cove. Project Narrative 5-4 Sediment Deposition Mitigation - Lake Houses at Eagle Cove .r Grading Plans (12 copies) Applicability: Item 10 — Grade and Fill Permit Application Item 30 — Shoreline Substantial Development Permit Application Grading Plans All plan sheets are provided in reduced form on 8.5" x I I" paper. Larger versions (22" x 34") can be generated as necessary. Each plan sheet indicates graphic scale and north arrow. Dimensions of all properties are provided. Because the entire project is located in the water, shoreline structures are only generally located as they will not be changed, altered or affected by dredging work in Lake Washington, Similarly, no drainages or other surface changes, (above the Ordinary High Water Level) or utilities will be impacted. As discussed in the Project Narrative the volume of material to be dredged exceeds 500 CY. The following project plans are provided" • Sheet 1 of 5 — Existing Lake Bed Elevation Contours as of July, 2016 when last surveyed. Because the May Creek Delta is an extremely active source of sediment t deposition arising from uncontrolled erosion process in the May Valley, Lakebed elevations will continue to change as more sediments are deposited at the project site. Existing contour lines are drawn at two -foot intervals. • Sheet 2 of 5 — Proposed Dredging Contours (Grading) are provided. The proposed contours provide the deepest that we are proposing to dredge. However, for any given dredging event, it may be that less material may be dredged than permitted by the City of Renton. For example, during the last permit cycle, the City of Renton permitted the dredging of the May Creek Delta, however, the permit obtained from the US Army Corps of Engineers encompassed a much smaller area. • Sheet 3 of 5 — Cross Section Al to A-2 provides a graphical presentation of existing and proposed dredging contours. To facilitate understanding of the profile, the cross-section at Al to A2 is also provided as a 4X vertical exaggeration. • Sheet 4 of 5 — Cross Section BI to B-2 provides a graphical presentation of existing and proposed dredging contours. To facilitate understanding of the profile, the cross-section at B 1 to B2 is also provided as a 4X vertical exaggeration. Item 10 Grading Plan 10- 1 Sediment Deposition Mitigation - Lake Houses at Eagle Cove • Sheet 5 of 5 Mitigation/Environmental Enhancement / Large Woody Debris. Applicant seeks to place Large Woody Debris at the northern property line at the north end of the project site as recommended/suggested by Washington Department of Fish & Wildlife. Six root wads will be secured to existing boom logs to enhance shallow water habitat for fishes at the periphery of the May Creek Delta. Because of the variability and unpredictability of sediment deposition, it is entirely like that contours shown in Sheet l of 4 will change. Upon completion of dredging, finished contours in the project area will be provided to the City of Renton. In major part, this grading plan also incorporates rehabilitation planning for mitigating uncontrolled sediment deposition to the project site.

This "fish window" runs from July Ith to September 15`h of each year during the 5 year permit duration. The intent is to protect potential spawning salmon and other fisheries in Lake Washington and nearby May Creek. Pending approval of permits from the City of Renton, the HPA will be amended. 7.2 Days and Hours o, f Operation In -water work (Environmental Enhancement and Dredging) will occur during daylight hours between 7 AM and 7 PM on weekdays to minimize noise impacts to neighboring residences on weekends and evenings. Daylight hours are also substantially more protective of worker safety. Additionally, daylight hours will better allow for visual observation of dredging activities, potential turbidity generation during dredging, salmon and other fishes observation (preservation/protection), and dealing with potential emergencies that may arise. 7.3 Proposed Hauling/Transportation routes/Preliminary Traffic Control Plan The materials to be dredged are principally fine to medium sands with some gravel that is well - draining fill material. Sediments do not contain any substantial silt or clay. There are three potential options for handling this material. Option I - Off-loading at the boat ramp on Lot A and trucking the materials off site Option 2 — Off-loading the barge at a site on Lake Washington or Lake Union (TBD) Option 3 Open Water, Ocean Disposal Option 1. It may be possible to off-load sediments directly to trucks at the Boat Ramp at Lot A. Sediments would be placed on a flat barge and allowed to "dry" to the extent that water will not leak during transit. If "free" water is observed, then trucks will be lined to eliminate Item 7 —Construction Mitigation Description 7-1 Sediment deposition Mitigation - The Lake Homes at Eagle Cove drippage on public highways. The major downside to this option is having to haul sediments through the Barbee Mill Development and potentially disturb residents more than other options. Dry sediments would be hauled off -site for sale or other beneficial use. Clean sands are a commodity in demand, so this is a viable option in that regard. Option 2. Clean sediments can be dredged to a barge and off-loaded to another site on Lake Washington (outside of the City of Renton or Lake Union for off-loading and beneficial reuse. Currently, negotiations have been underway for a site (not in the City of Renton) that may be an opportunity for receiving sediments for beneficial reuse. For example, it may be that the City of Renton or other "lake municipalities" will have an interest in obtaining clean sands and gravels delivered to their door. Option 3. Ocean disposal is an option for receiving clean sediments from the project site at the Puget Sound Open Disposal site. Additional sediment sampling may be necessary to meet USACE requirements for ocean disposal. While ocean disposal is available, it seems to be a counter -intuitive use for clean materials that can be beneficially reused. 7.4 Measures to be Implemented to Minimize Dust, Erosion, Mud Dust Abatement. Because sediments are well draining, they will be damp but not wet with a low potential for generating dust. No special dust abatement measures are anticipated during dredging and handling on site. If sediments are trucked off -site, all trucks will be covered to minimize dust generation or potential wind generated loss... Erosion Control. No upland soils or structures will be impacted or modified in any way at the project site. Sediment deposition mitigation dredging should not cause any in -water impacts as regulated by the Department of Ecology in their Water Quality Certification. Potential turbidity will be monitored in real time during in -water work Dredged sediments will be placed on a flat barge that will be lined with straw bales wrapped in erosion control fabric to minimize potential turbidity in return water, as sediments further dewater in accord with anticipated Water Quality Certification. If either Option 1 or Option 2 is implemented for handling sediments, a detailed Traffic Control Plan will be generated and implemented (see section 7.5) Mud Control. Dredging operations will be conducted at all times to minimize disturbance or siltation to adjacent waters. Because dredged materials are principally sandy sediments with nominal silt or clay, virtually no mud will be generated by this project. In the event of excessive turbidity, fish distress, fish kill, or other water quality problem, dredging operations and placement will be stopped until the problem is corrected, and the Department of Ecology has been notified. Noise Control. Dredging will occur during daylight hours to minimize noise to neighboring businesses and residences during weekend and nighttime hours. Some temporary increase in noise is unavoidable from the operation of heavy equipment. Noise levels will approximate those generated by equipment operated at the former sawmill. Potential noise impacts may Item 7 — Construction Mitigation Description 7-2 Sediment Deposition Mitigation - The Lake Homes at Eagle Cove be limited by utilizing equipment that is well muffled. Because sound travels over water very well, baffles on the dredging equipment will be installed if noise levels are unacceptable. Other Noxious Characteristics. Sediments have been previously sampled and tested for potential contamination. Test results from multiple testing events over the years indicate that sediments are clean sands and gravels. No sediment quality criteria have been exceeded, and sediments present no substantial environmental threat to human health or the environment. Nevertheless, a spill of petroleum products (hydraulic fluid, diesel, other) is always a concern. All equipment operating over -water will be enclosed with a containment boom to capture a potential spill and to aid in cleanup by not allowing a potential spill to spread or disperse. Most dredging contractors now use a peanut or other vegetable —based hydraulic oil to minimize petroleum releases. Contractors will carry spill control materials on board floating equipment so that in the event of a spill or leak, there will be no delay in containment to minimize potential impacts. An approved Spill Control and Countermeasures Plan (SPCC Plan) is required by the Coast Guard for all equipment operating in/over water. A copy of the selected contractor's plan will be provided to the City of Renton. This plan will be implemented in case of a spill, or leak. Because of this potential for a spill, prevention and a proactive approach is always the best measure. A trained and educated work force, trained in spill protection and cleanup is essential. Additionally, it is critical that all equipment is maintained in good operating condition and all hydraulic lines and fittings be routinely inspected on a daily basis. The most common leak to the waters of the state arises from failing hydraulic hoses and fittings. Refueling of equipment over the water will not be allowed during the short duration of the project. . These risks can and will be minimized with maintained equipment, trained personnel, equipment inspections, containment booms, and related proactive measures to minimize the potential impacts arising from a spill or a leak into the waters of the state.. 7.5 Preliminary Traffic Control Plan In Section 7.2 above, we detailed and discussed the primary options for beneficial reuse or disposal of sediments. A full traffic control plan will be prepared, and submitted to the City of Renton for review and approval of a "hauling permit" if dredged materials are trucked off site on public highways. It is currently anticipated that approximately 2,500 to 3,000 CY of sandy sediments will be moved during the next dredging event. This would translate to approximately 350 truck loads. If tandem trucks are used, the number of trips would be reduced by 50%. If dredging occurs over 10 day period, that would equate to approximately 35 tandem trucks per day during approved hauling times of lower traffic volume. Hauling of sediments will not occur on weekends. The preliminary haul route for trucks will leave the project site is as follows: • Travel north on Lake Washington Boulevard N, Item 7 — Construction Mitigation Description 7-3 ciry o� DEPARTMENT OF COMMU....

These environmental enhancements include, replacement of a solid float with a high light -transmission grated float, extraction of treated and untreated wood plies, replacement of wood piles with four galvanized pipe piles, removal of several large angular rocks at base of basaltic columnar rockery, and placement of approximately 20 CY of rounded river rock (aka, "fish rock") at the rockery These environmental enhancements are in response to approval of a ten year Shoreline Substantial Development Permit (LUA05-138) for dredging the mouth of May Creek where sediments collect to prevent flooding of the Barbee Mill property and to maintain navigational depths to an existing boat house. These mitigation measures were required as a part of permit approval, and are approved by USAGE (NWS-2007-10-19). The environmental enhancement work is anticipated to be completed during the approved in -water work window in accordance with HPA requirements. The anticipated HPA in -water work window is July, 16 through September, 15 of this year. The applicant is proposing to replace a solid wood float, approximately 25' immediately south of the boathouse. The solid float is 32' long and has an area of 256 sf. A new float that is 24' long and has a surface area of 192 sf will be installed. The new float is 25% smaller. The entire surface area of the Float will be grated with high light -transmission grating (>63% light transmission) to substantially improve light transmission to near -shore, shallow water habitat_ Three treated piles will be extracted and replaced with Page Iof4 City of Renton Deportment of Community nomic Development Certificcte of Exe n from Shoreline Sub stcnbol Development Barbee Mointenonce Dredging Mit?gatron Shoreline Exemption WAI6-000383, &W two smaller galvanized pipe piles to eliminate creosote treated piles . Approximately ten treated piles at the replacement float, mentioned above, will be extracted in accordance with Washington Department of Fish and Wildlife (WDFW) requirements and procedures. Additionally, two dolphins, consisting of three piles each, will also be extracted. Because there may be "stubbed" piles, below the water line, the number of piles is stated as approximate. Extracted piles will be cut into small lengths for disposal at an approved landfill. At no time will any treated wood piling be reused for any purpose. Four pipe piles will be installed. As mentioned above, the three piles at the float will be replaced with two 10" galvanized pile piles to secure the new grated float. Two 12" galvanized pipe piles will be installed to replace the two dolphins identified immediately above. The applicant is proposing to remove several large angular basaltic rocks in the water at the base of the rockery approximately 75' south of the boathouse These rocks will be removed from the water and taken off -site. Approximately 20 CY of approved fish rock will be placed at the base of the rockery and at area immediacy south of the boathouse and adjacent to the existing boat ramp. Of this quantity about 2 or 3 yards will be placed near the boat ramp, and the remainder will be placed at the rockery.

Renton Washington, Brief description of proposed work: The proposed work consists of environmental enhancements and mitigation measures; arising from state and Federal permitting requirements, to improve near -shore shallow water habitat (see project plan). These environmental enhancements include_ • Replacement of a solid float with a high light -transmission grated Boat. + Extraction of treated and untreated wood piles - Replacement of wood piles with four galvanized pipe piles • Removal of several large angular rocks at base of basaltic columnar rockery + Placement of approximately 20 CY of rounded river rock (aka, "fish rack") at the rockery Float Replacement_ A solid wood float, approximately 25' irranediatefy south of the boathouse will be replaced. The solid float is 32' long and has an area of 256 sf. A new float that is 24' long and has a surface area of 192 sf will be installed_ The new float is 25% smaller. The entire surface area of the float will be grated with high light -transmission grating (>63% light transmission) to substantially improve light transmission to near -shore, shallow water habitat. Three treated piles will be extracted and replaced with two smaller galvanized pipe piles to eliminate creosote treated piles (see below) Extraction of treated/untreated-piles. Approximately ten treated piles at the replacement float (mentioned above) will be extracted in accordance with Washington Department of Fish and Wildlife (WDFW) requirements and procedures. Additionally, two dolphins, consisting of three piles each, will also be extracted_ Because there may be "stubbed" piles, below the water line), the number of piles is stated as approximate. Extracted piles will be cut into small lengths for disposal at an approved landf Il. At no time will any treated wood piling be reused for any purpose. Drive Galvanized pipe pilex. Four pipe piles will be installed. As mentioned above, 111e three piles at the float will be replaced with two 10" galvanized pile piles to secure the new grated Float. Two 12" galvanized pipe piles will be installed to replace the two dolphins identified immediately above. Angular Rock Removal. There are several large angular basaltic rocks in the water at the base of the rockery approximatcly 75' south of the boathouse. These rocks will be removed from the water and takun offsite. L'oyd & Associates, Inc. City of Renton- Shoreline Exen.,..on Request Placement of"Fish Rock"_ Approximately 20 CY ofapproved fish rock will be placed at the base of the rockery and at area immediacy south of the boathouse and adjacent to the existing boat ramp. Of this quantity about 2 or 3 yards will be placed near the boat ramp, and the remainder will be placed at the rockery. Basis for the Exemption: Completion of this project will improve shallow -water fish habitat. Anticipated dates of work: July -September 2016 Environmental enhancement work is anticipated to be completed during the approved in -water work window in accord with Hydraulic Project Approval (HPA) requirements. Anticipated HPA in -water work window is July 16 — September 15_ Other permits required for proposed project, USACE permit (NWS-2007-10 19) Department of Ecology approvals (Shorelines and Water Quality Certification) Hydraulic Project Approval (WDFW —not yet obtained). Current and proposed use of the site: Currently the site is entirely aquatic lands owned by project proponent. The work site is adjacent to the shoreline and used for navigational access to the boathouse and related recreational uses on lake Washington. There are no proposed changes to site use. Special site features The project site is unique waterfront on Lake Washington_ As stated above, the project proponent owns aquatic lands of the water front for four single family homes. There is a boathouse at the north end and a shared -use dock at the south end. The site is also near -lay Creek. Soil type and drainage conditions: Existing sediments at the project site at the north are principally sands and gravels (with rounded rock up to 8" in diameter) arising from May Creek lacustrine deposition. The sands and gravels grade to finer materials (fine sands and silt) at the south end as one moves further away from sands and gravels deposited by May Creek at the north end of the site (deposition occurs principally during severe storm events). When dredged, the sediments at the north end are known to be well draining sands and gravels with occasional rorutded rock. Estimated Construction and fair Market Value Costs. Construction costs are estimated to be approximately S65,000. The fair market value is harder to estimate, but permitting costs, delays, and transactional and administrative costs, if included in Fair market value, bump estimates substantially higher than the construction costs. There is also the difficulty of estimating the value to fishes and wildlife of enhanced shallow -water habitat. Fair Market Value? Just a guess at $300,000. Estimated Quantities and types of materials: Approximately 20 CY of rounded river rock (approved previously by WDFW) will be placed in the water at the rockery, as discussed above_ U old & Assacialo. Inc- City of Renton — shoreline Exec , ion Request Tree Removal: No trees will be removed. Distance from Ordinary High Water Line: All proposed environmental enhancements at the project site will occur in -water below the ordinary High Water Line (OHWL, — 21.8' feet, MSL, USACE datum). Nature of the Existing Shoreline: The existing shoreline is almost entirely a bulkhead composed of basaltic rock. A portion of this project is directed at removal angular rock at the base of the bulkhead and soltenang the shoreline along the base of the rockery with rounded fish rock_ Height Restrictions: No structures are proposed in this environmental enhancement project.
