Lake and Stream Study 1
Project Purpose
The project purpose is to install a boatlift, canopy, and jet ski lift at the existing shared pier.
Location
The subject property is located at 3905 Lake Washington Boulevard North (King County parcel
number 3342700011) in the City of Renton, Washington (see Figure 1 – Vicinity Map). The
parcel is on the waterfront of Lake Washington.
Project Description
The work will install a boat lift, translucent canopy, and dual jet ski lift at an existing shared pier.
A native planting plan with 6 shrubs will be planted along the shoreline.
During construction, a floating boom will surround the work barge, pier, and work area.
Project drawings are included in Appendix A.
Approach
Northwest Environmental Consulting LLC (NWEC) biologist Courtney Straight conducted a site
visit on May 22, 2020 to evaluate conditions on site and adjacent to the site. NWEC also
consulted the following sources for information on potential critical fish and wildlife habitat along
this shoreline:
• City of Renton COR Maps online database
(https://rp.rentonwa.gov/HTML5Public/Index.HTML?viewer=CORMaps)
• Washington Department of Fish and Wildlife (WDFW): Priority Habitats and Species
online database (http://apps.wdfw.wa.gov/phsontheweb/)
• Washington State DNR Natural Heritage Features database
(https://www.dnr.wa.gov/publications/amp_nh_trs.pdf?znn6z)
• WDFW SalmonScape online database of fish distribution and ESA listing units
(https://apps.wdfw.wa.gov/salmonscape/)
Site Description
The subject property is in a residential neighborhood. It has shoreline on its west boundary with
single-family homes to the north and south. Lake Washington Boulevard North and the East Rail
Corridor Trail are present to the east.
The only existing structure on the property is a single-family residence. The property has a
shoreline consisting of a rock bulkhead, planted native vegetation, a concrete walkway, and a
DocuSign Envelope ID: FB3E4A10-FACD-4E1B-B090-8AF05FD63D1E
3905 Lake Washington Blvd N
Lake and Stream Study 2
fully grated pier at the south property line. The pier includes two deeded slips for neighboring
properties (Photos 1 through 4).
The substrate of the lake is sand and cobble. No milfoil was observed during the site visit.
The shoreline on the property has a rock bulkhead (Photo 5) with a grated ramp from the
shoreline to the pier (Photo 6). The property to the north has a rock bulkhead (Photo 5) and the
property to the south has a rock bulkhead with wooden pier (Photo 7). The property contains
shoreline native plantings, and a poured concrete walkway that starts approximately 10 feet
from the bulkhead and continues landward to the house approximately 3 to 4 feet (Photo 8). The
property line to the north has a walkway that goes between the subject property and the
property to the north with a hemlock tree, evergreen huckleberry, thimbleberry, dogwood
shrubs, and sword fern. The middle of the shoreline has dogwood shrubs, black cottonwood,
sword fern, and red-flowering currant. The south end of the shoreline has the ramp and pier with
plantings of Pacific willow, evergreen huckleberry, beaked hazelnut, and snowberry. Most of
these shrubs and trees are overhanging the water, providing shade to the lake. Approximately
250 feet north of the subject property is the mouth of May Creek (Photo 9).
Lake and Stream Classifications
As a Shoreline of Statewide Significance (RMC 4-3-090B1) Lake Washington is defined as a
Shoreline of the State (RMC 4-11-190S). The Shoreline is designated as “Shoreline Residential”
and as a reach of Lake Washington (Figure 2 – Renton COR Map). May Creek is a salmon-
bearing stream, classified as a Type S stream and included within the definition of a Shoreline
of the State (RMC 4-3-090B1).
Ordinary High Water Mark
The Ordinary High Water Mark (OHWM) for Lake Washington is the line of mean high water
(RMC 4-11-150 Definitions O). The Lake Washington water depth is controlled by the Army
Corps of Engineers at the Hiram M. Chittenden Locks and is at 21.8 feet above sea level (Corps
of Engineers Datum). The OHWM at the project site is shown in Appendix A.
Vegetative Cover of the Site
There are no wetlands or floodplains in the study area, but it does include Lake Washington
riparian areas. The homeowner’s association for the housing development located along the
shoreline, including the subject property, requires that residents plant only Washington State
native plants in all outdoor landscaping and along the shoreline. Riparian and overhanging
vegetation includes Pacific willows, dogwoods, vine maple, thimbleberry, evergreen
huckleberry, sword fern, black cottonwood, and western hemlock. There are no DNR Natural
Heritage Features listed in the study area (Figure 3 – Natural Heritage Features).
Ecological Functions of Lake Washington Along Study Area
Existing native plantings in the study area provide habitat functions along the shoreline. Planting
additional native plantings will further increase habitat conditions at the project site. These
plants will provide overhanging cover for fish, structural diversity for birds and wildlife, detritus
DocuSign Envelope ID: FB3E4A10-FACD-4E1B-B090-8AF05FD63D1E

for aquatic invertebrates and long-term recruitment of woody material and other allochthonous
food sources.
Species Use
Birds
Birds observed near the site include raptors, herons, eagles, cormorants, waterfowl, and
songbirds. There is an osprey platform located approximately 220 feet from the end of the pier.
It was previously used by nesting osprey, but no osprey or nest was present during the site
study within nesting season. Bald eagles, protected by the Bald and Golden Eagles Protection
Act and the Migratory Bird Treaty Act, are protected as a “sensitive species” within the state of
Washington (WAC 232-12-011). Eagles were observed in the area during the site study, but no
nest was visible along the shoreline.
Mammals
No wild mammals were observed during the site study, but Lake Washington is known to have
river otters, beavers, nutrias, and muskrats. Deer and coyotes are known to be present in the
vicinity.
Fish
WDFW’s PHS mapping and SalmonScape mapping tools show the following salmonid species
using 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 Salmonscape database maps the site as critical habitat to the Endangered Species
Units (ESU) of Threatened Chinook and steelhead (Figure 4 – SalmonScape Map). Sockeye
are known to spawn along the shoreline approximately 1,000 feet south of the project area. The
nearest spawning stream is May Creek, located approximately 250 feet north of the project
area, is modeled by Washington Department of Fish and Wildlife (WDFW) for spawning of non-
listed coho and sockeye and listed Fall Chinook. Juveniles may rear in the waters near the
project when traveling from spawning sites on other lake tributaries to the lake’s outlet at the
Locks. The project site is accessible to any fish migrating or rearing in the lake, and Lake
Washington is designated as critical habitat for Endangered Fall Chinook salmon.
There is a Freshwater Forested/Shrub Wetland approximately 0.5 mile north, but no other
priority habitats are directly associated with the project site for aquatic or terrestrial species
(Figure 5 – PHS Map).
Measures to Protect Trees and Vegetation
No trees or vegetation will be disturbed during the project as all work will occur in-water.
Project Impacts and Conservation Measures
Direct Impacts:
DocuSign Envelope ID: FB3E4A10-FACD-4E1B-B090-8AF05FD63D1E
3905 Lake Washington Blvd N
Lake and Stream Study 4
Sediments: Sediment disturbance will occur 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 will be placed around the pier and barge to contain floating
debris to the project site. The project will meet state water quality standards.
Shoreline: The shoreline is planted with native vegetation that will be preserved throughout the
proposed work. Native vegetation maintains habitat functions by providing shade along the
shoreline. These 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.
Lakebed: The lakebed coverage will be unchanged.
Noise: Construction will create noise audible to neighbors and in-water. Noise disturbance will
be short-term and should have negligible effects on fish and wildlife in the area.
Potential spills: Short-term risks include the potential for petroleum spills that can occur with
any equipment operation. The level of impact to the aquatic environment is expected to be
minor because of the small amount of petroleum products available for spillage during typical
construction activities, and because of spill containment measures that will be employed should
a spill occur.
Indirect Impacts:
Shading: The overwater coverage will be unchanged as the proposed canopy will be 100%
translucent.
Recreational Boating: The project supports continued recreational boating, which has been
identified as a limiting factor for salmonid populations in Lake Washington. The pier
replacement will not introduce additional boating to Lake Washington, as the owners could still
access the lake from a public boat launch or private moorage facility.
Other Conservation measures:
Work window: The work will be completed during the prescribed in-water work window for this
area of Lake Washington (July 16 to December 31). Operating within this time frame helps
protect Chinook salmon, steelhead, bull trout and other salmonid fish species.
Best Management Practices: Applicable BMPs will be used such as a floating boom around
the in-water work area will contain any floating debris that may escape during construction. The
barge will have a perimeter containment sock to absorb oil and grease that may wash from the
barge during construction.
Hazardous material containment materials such as spill absorbent pads and trained personnel
will be required onsite during any phase of construction where machinery is in operation near
surface waters.
Avoidance and Mitigation
The proposal is to build a boat lift requiring work within Lake Washington making it impossible to
avoid impacts to the Lake while completing the project. Minimization of impacts includes the use
of BMPs and timing of the in water work as per WDFW and the Corps of Engineers guidance.
Project impacts will also be minimized by placing the boat lift and jet-ski lift in the deepest water
possible. Generally, to protect outmigrating juvenile salmonids, WDFW and NMFS have
DocuSign Envelope ID: FB3E4A10-FACD-4E1B-B090-8AF05FD63D1E

Lake and Stream Study 5
determined that the most critical zone is within 30’ of the shoreline. Due to the topography of the
shoreline to the south of the dock running parallel to the main walkway moving the lift and
canopy further west would not place them 30’ beyond the shoreline. The waterward side of the
lift will be in water approximately 11 feet deep. At this depth the effects of propwash should be
negligible. Propwash is one of the primary concerns of placing moorage close to the shoreline.
Being a joint-use dock the boat lift cannot be placed on the north side of the dock to move it
further from the parallel shoreline. Placing the boat lift further west would expose the boat to
additional wave action when trying to moor which could cause damage to the boat when trying
to moor in rough waters. Placing the boat lift in deeper water would require additional
reinforcement to the lift framing offsetting the benefits of moving it into deeper water. The jet-ski
lift cannot be placed on the waterward side of the boat lift because it will block the boat from
using the moorage. Therefore we believe as proposed the lifts and canopy are placed as far
waterward as feasible and safe.
Mitigation
Some impacts to the Lake will occur despite attempts to place the boat lift in the deepest water
possible at the site. In order to meet the City of Renton Code and WDFW requirements the
owner is proposing to plant 6 shrubs including snowberry and red flowering currant within 10
feet of the shoreline. In addition, angular cobble has become imbedded in the shoreline
sediments that was probably dropped when building the current bulkhead. Non-structural cobble
will be removed from the lake along 123 linear feet of shoreline enhancing the shoreline over
existing conditions.
Conclusion
Juvenile Chinook salmon, and other salmonids, rear and migrate along the Lake Washington
shoreline.
There will be temporary impacts from noise and disturbed sediments during installation of the
lifts and copy. The overwater coverage will not be increased as the canopy will be translucent.
The project will minimize construction effects on the environment by following the prescribed
fish window and use applicable BMPs to prevent construction spills and debris from escaping
the area.
The boat lift and jet-ski lift are being placed in the deepest water possible where effects of
propwash are negligible. In addition 6 native shrubs will be planted along the shoreline and
angular cobble that has been dropped into the lake will be removed along the shoreline.
This project has been designed to meet current residential mooring standards and will use Best
Management Practices to reduce project impacts. The conservation and mitigation measures
are designed to improve ecological functions or prevent further degradation of habitat and will
result in No Net Loss of ecological functions at the site.
