The project site and adjacent properties are zoned as R- 10. The site is on the shoreline of Lake Washington (Reach C) within the Shoreline Residential and Aquatic designations. The shoreline is armored with a concrete bulkhead. The proposed boat lift would be located approximately 128’ waterward of the ordinary high water mark on the south side of the pier. The boat lift would be 10’-9” wide by 13’-5” long. The bunk of the boat lift would extend 18” above the ordinary high water mark and the lift will sit on the lake bed of Lake Washington on foot pads that are 12” by 18”. The lake bed consists mostly of sand and gravel where the lift will be located. No dredging, fill, or excavation would be done for the project. Site Area: 7,787 sq. ft. (0.18 acres) STAFF RECOMMENDATION: Staff Recommends that the Environmental Review Committee issue a Determination of Non-Significance-Mitigated (DNS-M). City of Renton Department of Community & Economic Development Environmental Review Committee Report KERJIWAL BOAT LIFT LUA22-000083, ECF, SSDP Report of May 9, 2022 Page 2 of 5 SR_ERC Report_Kejriwal Boat Lift_FINAL PART ONE: PROJECT DESCRIPTION / BACKGROUND The applicant is requesting Environmental (SEPA) Review and Shoreline Substantial Development Permit proposing to install a new boat lift on the Barbee Mill Community Organization dock located at 4151 Williams Ave N (Parcel # 0518500350) for future use by a resident of the Barbee Mill development. The dock was constructed in 2010 under a separate Shoreline Substantial Development Permit (LUA10-006). The proposed boat lift would be located on DNR- owned parcel # 051850HYDR approximately 128’ waterward of the ordinary high water mark (OHWM) on the east side of the existing finger pier. The lift would be approximately 11’ wide by 13’ long. The bunk of the boat lift would extend 18” above the OHWM and would sit on foot pads that are 12” by 18” on the lake bed. The shoreline near the proposed boatlift area consists of a sheet pile and concrete bulkhead. The land is continuously below water through the maintained lake water level. On the uplands side of the mentioned bulkhead, native vegetation along the shoreline has been planted through the residential subdivision development and as part of the Community Dock construction. The substrate or lake bottom where the subject boat lift would be located consists of medium-sized angular rock and cobble. The project site is located at the former Barbee Mill lumber mill site which is now the Barbee Mill residential subdivision. The proposed lift would be located within Lake Washington along the subdivision’s shoreline, which is a Shoreline of the State and falls under the City’s regulated Shoreline Jurisdiction. The proposed location of the lift is within a DNR lease parcel (#0518500350). During the original construction of the Community Dock, DNR approved the use of the finger pier on the lease parcel for the property owners residing at 4125 Williams Ave N. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day Appeal Period. B. Mitigation Measures 1. Shading impacts associated with the proposed boat lift shall be mitigated through the planting of 10 snowberry plants along the shoreline of the residence at 4125 Williams Ave N, which is located to the south of the community dock. C. Exhibits Exhibit 1 Environmental Review Committee Report Exhibit 2 Dock Easement Exhibit 3 Site Plan Exhibit 4 Lake Study, prepared by Northwest Environmental Consulting, LLC, dated November 2021 Exhibit 5 Advisory Notes to Applicant 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. Water (Streams/Lakes) Impacts: The applicant submitted a Lake Study (Exhibit 4), prepared by Northwest Environmental Consulting, LLC, dated November 2021 with the project application materials. According to RMC 4-3-090, residential boatlifts should be designed in a manner that directs land alteration to the least sensitive portions of the site and as far waterward as feasible and safe. The applicant has proposed the boat lift to be located approximately City of Renton Department of Community & Economic Development Environmental Review Committee Report KEJRIWAL BOAT LIFT LUA22-000083, ECF, SSDP Report of May 9, 2022 Page 3 of 5 SR_ERC Report_Kejriwal Boat Lift_FINAL 128’ waterward of the OHWM away from the riparian buffer installed as part of mitigation for the community dock constructed in 2010 (LUA10-006). Installation of the lift is anticipated to take one (1) day to complete. The lift is proposed to be installed during the in-water work window at the site is open from July 16th through December 31st. The lift will be brought to the site via a barge. The Lake Study proposes to plant 10 snowberry plants along the shoreline of their residence at 4125 Williams Ave N, which is just to the south of the community dock, as mitigation for the potential shading impacts anticipated by the proposed boat lift. Staff recommends, as a SEPA mitigation measure, that shading impacts associated with the proposed boat lift be mitigated through the planting of 10 snowberry plants along the shoreline of the residence at 4125 Williams Ave N, which is located to the south of the community dock. Mitigation Measures: 1. Shading impacts associated with the proposed boat lift shall be mitigated through the planting of 10 snowberry plants along the shoreline of the residence at 4125 Williams Ave N, which is located to the south of the community dock. Nexus: SEPA Environmental Regulations 2. Plants and Wildlife Impacts: The proposed project would take place primarily in-water and no disturbance of the restored upland vegetation would occur. The submitted Lake Study (Exhibit 4) notes that the upland portion of the project site includes a sheet pile bulkhead, planted native vegetation (Pacific willow, red osier dogwood, kinnikinnick, and Oregon grape), a concrete walkway, and a fully grated community pier. The substrate of the lake in the vicinity of the proposed boat lift is sand and cobble. Milfoil was observed starting five feet from the bulkhead and continuing waterward. The existing native plantings in the study area provide habitat functions along the shoreline. The proposed planting of additional snowberry plants would further increase habitat conditions at the project site. These existing and proposed plants provide overhanging cover for fish, structural diversity for birds and wildlife, detritus for aquatic invertebrates and long-term recruitment of woody material and other allochthonous food sources. The following bird species were observed on or near the project site: raptors, herons, eagles, osprey, waterfowl, and songbirds. In addition, the following salmonids species are known for utilizing Lake Washington for migration and/or rearing: residential coastal cutthroat (Oncorhynchus clarki), winter steelhead (O. mykiss), Dolly Varden/bull trout (Salvelinus malma), sockeye salmon (O. nerka), fall Chinook (O. tshawytscha), coho salmon (O. kisutch), and kokanee (O. nerka). The project site is mapped as critical habitat to the Endangered Species Units (ESU) of Threatened Chinook and steelhead. The installation of the proposed boat lift would result in temporary sediment disturbance below the OHWM and along the shoreline of Lake Washington. Additionally, the tug and barge propwash may disturb sediments temporarily when making trips to/from the site. Juvenile salmonids could be temporarily displaced or stressed by increased turbidity. A floating boom would be placed around the work area to contain floating debris to the project site. The lift is proposed to be installed during the in-water work window at the site is open from July 16th through December 31st. The lift will be brought to the site via a barge. As discussed above, the Lake Study proposes to plant 10 snowberry plants along the shoreline of their residence at 4125 Williams Ave N, which is just to the south of the community dock, as mitigation for the potential shading impacts anticipated by the proposed boat lift. Impacts to both wildlife and plants created by the boatlift construction are expected to be limited, therefore no further mitigation is recommended. Mitigation Measures: None The proposal has been circulated to City Department and Division Reviewers. Where applicable, their comments have been incorporated into the text of this report and/or listed under Exhibit 5 “Advisory Notes to Applicant”. ✓ Copies of all Review Comments are contained in the Official File and may be attached to this report.
