B. Project Description:
The proposed project is a joint-use pier to be located along the common property line between two abutting lots,
4113 and 4119 Williams Ave N, Renton, W A 98056 (Figures I and 2). The properties are located within the Barbee
Mill community, a major waterfront subdivision currently under development by Conner Homes at Barbee Mill
LLC along the eastern shore of Lake Washington. The two lots are referred to jointly as the "subject property"; the
property owners are jointly the "applicant" for the requested shoreline substantial development penn it. The
proposed joint-use pier would provide moorage and facilitate access to Lake Washington for residents of the subject
property and their guests. The Barbee Mill community dock is a day use only structure and does not provide
adequate full-time moorage for the waterfront lot owners. In addition to a landing and moorage facility for
watercraft, the proposed joint-use pier would be suitable for launching canoes and kayaks, sun-bathing, swimming,
fishing, water skiing and any number of other water sports and activities.
The Barbee Mill community is located on the approximately 22 acre site of the fonner Barbee Mill Company
lumber mill. Lots 23 through 48 are lakefront lots; the subject property is situated on lots 37 and 38. Upon
completion, the Barbee Mill community will have 114 multi-story paired homes, a pond, walking trails and
lakefront open space for the use of residents. Waterfront open space and trails are also located along May Creek,
which flows through the Barbee Mill community. The distance from the closest point (the southeast property line of
Lot 38) to the OHWL of May Creek is 195'. The project location itself is 130' from the southeast property line of
Lot 38. Therefore, it is 325' from the project location to the OHWM of May Creek. A street and the May Creek
open space (a riparian buffer) cover the area between the subject property and the May Creek boundary.
C. Habitat Data:
As a fonner industrial site, the general development area, including the subject property, was subject to decades of
disturbance and degradation by human activity. The Lake Washington shoreline was heavily bulkheaded, back-
filled and covered with impervious asphalt paving. Numerous piling and substantial quantities of concrete rubble
and other shoreline debris were on site. To restore this fonner industrial site to a parcel suitable for a residential
waterfront subdivision, upland and in-water structures including the mill buildings, timber bulkhead and piling were
removed, shoreline rubble was removed, fill soil was excavated to subgrade elevations, and toe rock and a
temporary quarry spall erosion control benn were installed. In addition, extensive shoreline restoration was
completed which included using sand, gravel and rock materials to construct a beach to mimic natural conditions

and installing coir rolls along the Lake Washington ordinary high water line. No additional excavation, grading,
clearing or fill material will be required for the proposed pier project. The southern 18 feet of 4113 is rock and the
remaining shoreline of 4113 and all of 4119 is sheet pile with a concrete cap. Both properties shoreline total 78'
long. The substrate immediately waterward of the bulkhead consists oflarge and small cobble.
The subject property is located south of, and was not included in, the area requiring the most extensive remediation.
The study area includes no wetland or flood hazard areas but it does include Lake Washington riparian areas. Prior
to the site restoration, riparian vegetation was found to be generally absent in the Barbee Mill community
development area due to extensive paving. In unpaved areas, vegetation noted included Juncus effusus (soft rush)
and Iris pseudocaris (a non-native iris). In accordance with the general development mitigation planting plan, native
.plants were installed along the entire Barbee Mill community Lake Washington shoreline, including the subject
property shoreline. In conjunction with construction of the proposed joint-use pier, additional native plants, shrubs
andlor trees will be planted as specified in applications to, and as approved by, the Washington State Department of
Fish and Wildlife and the U. S. Anoy Corps of Engineers (Figures 6-8).
Until the extensive site restoration was completed, the industrial use of the property limited the ecological functions
that would otherwise have been provided by Lake Washington and its adjacent riparian area. As a result of the
extensive remediation, beach reconstruction and plantings, the ecological functions of the Lake Washington
shoreline within the study area should be greatly enhanced. The addition of riparian vegetation to this formerly
near-barren site should help water quality by filtering pollutants, removing nutrients and reducing sediments in any
runoff from the adjacent upland development while helping to stabilize and protect the shoreline from erosion. The
riparian vegetation planted and to be planted should increase the habitat available for aquatic invertebrates and fish;
the addition of organic matter to the lake substrate from fallen and washed in leaves and woody debris will provide
them with food, shelter and shade. Increased overhanging vegetation will also provide shade and predator protection
for fish and aquatic invertebrates and may facilitate the migration of juvenile salmon. Terrestrial insects will benefit
from the food and shelter provided by newly planted vegetation, which in turn will provide an additional food
source for the birds and animals that feed upon them.
The Washington State Department of Fish and Wildlife Priority Habitat and Species database
(http://wdfw.wa.gov/hab/phslist.htm) identifies habitats and species considered to be priorities for conservation and
management. Listed species observed in the general Barbee Mill community development area include bull trout,
Puget Sound chinook salmon, Puget Sound steelhead, and marbled murrelet, all of which are discussed below.
Protected wildlife in Washington State shall not be hunted or fished (WAC 232-12-011). Protected wildlife noted
from time to time within the general Barbee Mill community development area include the marbled murre let and
the bald eagle. The marbled murre let is classified as a "threatened species," a species likely to become endangered
within the foreseeable future throughout a significant portion of their range within the state without cooperative
management or removal of threats. The bald eagle is no longer on the list of threatened or endangered species
under the Endangered Species Act (ESA) but continues to be protected by the Bald and Golden Eagles Protection
Act and the Migratory Bird Treaty Act and is protected as a "sensitive species" in Washington. Sensitive species are
vulnerable or declining and likely to become endangered or threatened in a significant portion of their range within
the state without cooperative management or removal of threats. The only eagle nests observed near the subject
property are two nests approximately 0.65 mile from the site on the opposite shore.

F. Action Area:
The action area should include the area within a one-mile radius of the project location. This area includes potential
turbidity and noise impacts from the construction process.
II. SPECIES AND HABITAT INFORMATION
A. Species Information:
In the project area, the Puge! Sound chinook (Oncorhynchus tshawytscha) is listed under the Endangered Species
Act as a threatened species according to the National Marine Fisheries Service (NMFS)(Federal Register, Vol. 64,
No. 56). On May 11,2007, NMFS also listed the Puget Sound steelhead (Oncorhynchus mykiss) as a threatened
species under the ESA (Federal Register / Vol. 72, No. 91/ Friday, May 11,2007/ Rules and Regulations). Bull
trout (Salve linus corifluentus) were listed as threatened by the United States Fish and Wildlife Service (USFWS) in
October of 1999.
On September 2,2005, NMFS issued the final rule designating critical habitat for 12 Evolutionarily Significant
Units (ESUs) of West Coast salmon, including the Puget Sound Chinook Salmon ESU and the Hood Canal
Summer-run Chum ESU. The project site is in an area designated as critical habitat for the Puget Sound Chinook
ESU (Federal Register I Vol 70, No.170 / Friday, September 2, 2005 Rules and Regulations). USFWS has
designated critical habitat in Lake Washington for Coastal-Puget Sound bull trout (Federal Register / Vol. 70, No.
185/ September 26, 2005 / Rules and Regulations).
Puglit Sound Chinook: Puget Sound chinook, also called the king salmon, are distinguished from all other Pacific
salmon by their large size. Most chinook in the Puget Sound are "ocean-type" and migrate to the marine
environment during their first year (Myers et al. 1998). They may enter estuaries immediately after emergence
as fly from March to May at a length of 40 mm., or they may enter the estuaries as fingerling smolts during May
and June of their first year at a length of 60-80 mm. (Healey 1982). Chinook fly in Washington estuaries feed
on emergent insects and epibenthic crustaceans (gammarid amphipods, mysids, and cumaceans). As they grow
and move into neritic habitats, they feed on decapod larvae, larval and juvenile fish, drift insects, and
euphausiids (Simenstad et al. 1982). These ocean-type chinook use estuaries as rearing areas and are the most
dependent of all salmon species on estuaries for survival.
MS&A
In the Lake Washington system, adult chinook salmon usually arrive at the Chittenden Locks in July, although
there are some arrivals before and after July (Synthesis of Salmon Research and Monitoring. 2008). According
to Fresh et al. (2000), the total time for salmon migration from the Locks to arrival at their tributary spawning
grounds "can take up to 55 days, but averages less than 30." During much of this time, salmon hold in the
upstream area from the Locks before moving through the Ship Canal and Lake Union. Fresh et al. (2000) found
the average holding time to be from 17 to 19. days. After reach their spawning streams between September and
November, spawning occurs from October to December.
According to Tabor et al. (2006), "Fry emerge from their redds from January to March. Juvenile Chinook
salmon appear to have two rearing strategies: rear in the river and then emigrate in Mayor June as pre-smolts,
or emigrate as fly in January, February, or March and rear in the south end of Lake Washington' or Lake
Sammamish for three to five months." In the project area vicinity, juvenile chinook salmon from the Cedar
River enter Lake Washington and rear in the south end of the lake primarily from January to May.
Tabor et al. (2006) also reported that:
Similar to results of 2002, juvenile Chinook salmon were concentrated in the south end of Lake Washington
from February to May ..... Therefore, it appears that the lake shore area near the natal stream is an important
nursery area for juvenile Chinook salmon. In Lake Washington, the major part of this nursery area appears
Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC Joint-Use Pier Project • 6
t
to be roughly from Pritchard Beach on the west shoreline and the mouth of May Creek on the east shore and
the south part of Mercer Island. The distance from the mouth of the Cedar River to the edge of the nursery
area is around 6 km. North of this area, the number of Chinook salmon would be expected to be relatively
low until mid-Mayor June.
In the same study cited above, it was found that marked chinook did not move far from their release site at Gene
Coulon Park (approximately 1.5 miles south ofthe current project site). Marked juveniles were observed 1,7,
15, and 21 days after release at Gene Coulon Park. All of the marked salmon that the investigators observed had
moved less than 150 m from their release site at the park.
After moving slowly away from the Green River and south Lake Washington, juveniles reach the Chittenden
Locks during the period between May and August, with peak migration through the Locks taking place in June.
According to Kerwin (200 I) chinook, coho, sockeye and winter steelhead use May Creek near the project site
for spawning, rearing and migration. However, volunteers from the Volunteer Salmon Watchers Program have
been observing salmon in May Creek since 2000. They have reported that only sockeye are seen consistently,
while chinook, coho, cutthroat trout and kokanee salmon are less commonly seen.
BuD Trout: Coastal-Puget Sound bull trout have ranged geographically from northern California (at present they
are extinct in California) to the Bering Sea coast of Alaska, and northwest along the Pacific Rim to northern
Japan and Korea. Bull trout are members of the char subgroup of the salmon family. Spawning occurs typically
from August to November in streams and migration to the open sea (for anadromous populations) takes place in
the spring. Eggs and juveniles require extremely cold water for survival. Temperatures in excess of about 15
degrees C are thought to limit bull trout distribution (Rieman and McIntyre 199~). They live both in fresh and
marine waters. Some migrate to larger rivers (fluvial), lakes (adfluvial), or saltwater (anadromous) before
returning to smaller streams to spawn. Others (resident bull trout) complete all of their life in the streams where
they were reared. Habitat degradation, dams and diversions, and predation by non-native fish threaten the
Coastal-Puget Sound population. The Coastal-Puget Sound bull trout population is thought to contain the only
anadromous forms of bull trout in the contiguous United States (Federal Register, Vol. 64, No. 210,1999).
Two subpopulations of bull trout (also known as "native char") are considered within the Lake Washington
area: the Chester Morse Reservoir population and the Issaquah Creek-Sammamish River population (Federal
Register, Vol. 64, No. 210, 1999). "Only two 'native char' have been observed during the past 10 years in the
Issaquah Creek drainage and none have been observed in the Sammamish River system. It is questionable
whether a viable subpopulation remains." (Federal Register, Vol. 64, No. 210, 1999).
Puget Souud Steel head: Wild winter steelhead enter the Lake Washington system in mid-December with peak
spawning taking place in May. There have been high rates of predation by California sea lions at the Ballard
Locks, which is one of the leading factors in the declining steelhead production in the Lake Washington system
(\992 Washington State Salmon and Steelhead Stock Inventory. Appendix One -Puget Sound Stocks.
• Washington Department of Fish and Wildlife, Olympia, W A.).
MS&A •
According to Kerwin (2001):
The Lake Washington system supports one native winter steelhead stock but not a summer steelhead stock
(SASSI 1994). The winter steelhead stock was listed in SASSI as "Depressed" but has recently shown some
evidence of rebounding. A limited hatchery program utilizing the native winter steelhead stock was initiated
in 1997 as a supplementation type program to assist in recovery of winter steelhead populations in the north
Lake Washington tributaries. The sharp decline in Lake Washington winter steelhead was noted as a reason
for concern by NMFS in their stock status review (Busby 1996).
However, in a more recent analysis, between 1986 and 2004 escapement for the Lake Washington winter-run
steelhead ranged from 1,816 (1986) to 44 (2004) (WDFW 2004). Based on the chronically low escapement and
. short-term severe decline in escapements, the stock status has decreased from its 1992 "depressed" status to
"critical" in 2002.
Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC Joint-Use Pier Project· 7
Marbled Murrelets: Marbled murrelets are small marine birds in the alcidae family. They spend most of their time
at sea and only use old growth areas for nesting. In the critical nesting areas, fragmentation and loss of old
growth forest has a significant impact on the survival and conservation of the species (WDW, 1993). Adult
birds are found within or adjacent to the marine environment where they dive for sand lance, sea perch, Pacific
herring, surf smelt and other smaJl schooling fish, and feed on invertebrates.
The project site is located in an urban environment adjacent to a major highway. There is a high level of
ambient noise in the project vicinity. There is no nesting habitat near the site. Therefore it is unlikely that
murrelets will be present in the project vicinity.
III. EFFECTS OF THE ACTION
The status of each of the listed species in the action area has been provided. The proposed project has been
described and the action area defined. When reviewing aJl the data, the potential direct and indirect effects of the
proposed action on the listed species and their critical habitat should be considered.
A. Direct Effects:
When considering the direct effects of the proposed project, one must determine if the proposed project will
immediately reduce or destroy the listed species and/or their habitat. The potential, direct impacts caused by the
construction process include increased noise and turbidity.
Pile driving noise: A vibratory pile driver will be used in the proposed project. If required, piles will be "proofed"
using a drop hammer pile driver with a 6" minimum block of wood between pile driver and pile. Feist et al.
(1992) reported that salmonids could be expected to hear pile driving noise approximately 2,000' from the
source. Based on the studies at the Everett Homeport, these researchers concluded that pile driving did alter the
distribution and behavior of juvenile pink and chum salmon. However, the Everett Homeport results may not be
entirely applicable to the proposed project, because a diesel powered compression hammer was used in that
study. As stated in the Feist report, "It would be reasonable to say that juvenile salmonids might respond
differently to the sounds of a vibratory hammer, compared to that of a diesel compression hammer."
As noted above, It is unlikely that murrelets will be present in the action area. Therefore, the construction
process should have little or no impact on marbled murre lets.
Tnrbidity: Increased turbidity caused by pile driving could, under certain circumstances, have adverse effects on
salmon and bull trout. The effects depend on duration of exposure, concentration of turbidity and the life stage
of the salmon during the increased exposure. The effects can be discussed in terms of lethal, sublethal or
behavioral (Nightingale and Simenstad 2001 a and Simenstad, editor, 1988). A silt containment curtain will be
installed in the project area to contain and minimize turbidity impacts.
To minimize the adverse. effects of increased turbidity and noise on migrating salmonids and bull trout, inwater
construction work will take place during the approved work window from July 16 to December 31. Overwater
work can proceed outside of the inwater work window.
B. Indirect Effects:
Indirect effects are effects of the project that occur later in time. For this project, indirect effects might include
alteration of juvenile salmon migratory pathways, increase in salmonid predation and reduction in prey resources
and refugia due to shading of the epibenthic substrate by the structure.

Freshwater: There were no studies specifically investigating the effects of piers on salmonid migration in lakes
cited by Kahler et al. (2000) in their review of pier-related impacts in lakes. Concerning the lake environment,
Kahler et al. (2000) state, "The question remains whether juvenile salmonids in lakes migrate under, or
otherwise utilize, piers, or ifthey avoid them and/or traverse their perimeter."
However, more recent reports have provided additional information concerning salmon responses to overwater
structures.
Tabor and Piaskowski (2002) noted that, "In February and March, chinook salmon were found using overhead
structures (piers, docks, and overhanging vegetation) during the day but in April and May, no chinook salmon
were ever observed using overhead structures. At night, chinook salmon rarely used overhead structures." The
authors hypothesized that the overhead structures were being used as a substitute for natural overhead cover
during the days in February and March.
In a later study, Tabor et al. (2006) noted slightly different results. They state that, "When migrating Chinook
salmon approach a pier they appeared to move to slightly deeper water and either pass directly under the
structure or swim around the pier. Most likely they move to deeper water as a way of reducing their predation
risk." The pier where these findings we made is approximately 7 .8' wide, 138' long and had solid decking. The
dimensions of the piers in the earlier study are not known. The results from the later study were noted in May
and July. whereas the 2002 study results were for the earlier months of February and March.
The results ofCeledonia et al. (2008) were similar to those of Tabor et al. (2000). Celedonia et al. stated,
"Juvenile Chinook salmon generally avoided areas directly beneath overwater structures. However, areas along
the edges of structures (within about 2 m horizontal distance) were sometimes used for prolonged periods (up to
2 hours in one case)." However, these authors offered the following qualifying statement:
These observations may be representative of holding fish near structures in general, but may not be an
accurate indication of how untagged Chinook salmon would generally behave upon voJitionally entering
these specific areas. Actively migrating fish (i.e., most fish released off-site and observed at the Seattle
Tennis Club site) often appeared to change course as they approached a structure. Structure width and water
depth appeared to influence degree of avoidance. Fish appeared less hesitant to pass beneath narrow
structures. Fish also appeared to move into deeper water to travel beneath or around structures.
These authors also observed:
Behavior at structures differed (i.e., swim beneath or travel around perimeter), and may have been related to
such interrelated factors as: fish size, light levels beneath the structure, degree of contrast at the light-dark
edge, width of the structure, height of the structure above the water surface, and water column depth
beneath the structure. Further study is needed to conclusively determine how these and other factors interact
to influence Chinook salmon behavior.
Marine Waters: In the marine environment, it is generally accepted that overwater structures can alter
migration behavior of juvenile salmon (though the effects may vary depending on the design and orientation of
the structure, degree of shading, and the presence of artificial light), and reduce salmon prey resources and
refugia by shading aquatic plant life (Simenstad et al. 1999; Nightingale and Simenstad 2001b). However, the
significance of these effects is not clear. As Simenstad et al. state, "We found no studies that described
empirical evidence supporting or refuting that modification of juvenile salmon behavior in shoreline habitats
was reflected in changes in survival." Nightingale and Simenstad (200Ib) state, "Presently, although we know
that under some conditions small juvenile salmon will delay or otherwise alter their shoreline movements when
encountering an overwater structure, the conditions under which this behavioral modification is significant to
the fishes' fitness and survival is relatively unknown."
A study by Williams et al. (2003) at the Mukilteo ferry terminal, found that, "Salmon fry were observed in all
nearshore habitats during each transect sampling period (day and night). The fry were observed under a wide
Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC Joint-Use Pier Project· 9
•
range of PAR values (0.0 I1mol m-2 s-1 to 2370 I1mOI m-2 s-I). Fry were observed both outside the terminal
and underneath the terminal at all times, and shadows produced by the 10-m-wide terminal structure did not
appear to act as barriers to fry movement at this location."
There is no question that underwater structures may alter migration patterns -that is not in dispute. As seen in
the study by Williams and in many other studies (see the literature review by Weitkamp -2003), there are
studies that indicate that salmon migration is not affected by the presence of overwater structures. Of course,
there are other studies indicating migration patterns are altered by overwater structures.
The issue is that no one has shown that these migration changes lead to increased mortality or decreased fitness.
None of the studies that report changes in salmonid migration patterns caused by overwater structures in the
marine environment have reported that these changes have a negative impact on salmonids.
Increased predation: An additional concern about the impacts of overwater structures on migrating salmon is that
they will be forced to move out into deeper water, where they will be consumed by predatory fish species.
However, in a study conducted in the marine environment, Williams et al. (2003) noted:
We found no evidence that avian, marine mammal, or fish predators consumed more juvenile salmon
near WSF terminals than along shorelines without overwater structures. Few species appeared to be
targeting abundant fry in nearshore habitats, and we observed only two occasions in which predators
(one tern sp., one staghorn sculpin) had consumed juvenile salmon.
The authors also state,
Our analysis of fish diets at the Mukilteo ferry terminal provides one piece of conclusive evidence that
juvenile salmon were not a major dietary component of predatory fish species during our study.
It should be noted that the Williams study was conducted in the marine, not lake, environment.
In Lake Washington, smallmouth bass migration into the littoral zone corresponds with the peak occurrence of
migrating salmonids in this zone (Fresh et al. 2001). Because of these similar migration patterns, salmon ids are
most at risk of predation from smallmouth bass in Lake Washington. Bass prefer complex, natural cover for
their foraging environment. When there is a scarcity of natural cover for foraging, as is the situation in Lake
Washington, they tend to use the dominant structures in the environment, such as pilings and piers, for foraging
cover (Kahler et al. 2000). There is concern that increasing the number of overwater structures will increase the
predation success of smallmouth bass on migrating salmonids.
Tabor et aI. (2004) investigated predation of juvenile chinook salmon in three areas ofthe Lake Washington
Basin. One of the areas they looked at was the south end of Lake Washington, an important rearing area. The
investigators found that:
The only predators observed to COnsume Chinook salmon were cutthroat trout, prickly SCUlpin (C. as per),
smallmouth bass (Micropterus dolomieui), and largemouth bass (M salmoides). Consumption of Chinook
salmon by cutthroat trout was observed in February, March and early April. Predation by prickly sculpin
was only observed in February. Smallmouth bass consumed Chinook salmon in May and June. Few
largemouth bass were collected; however, we did document a largemouth bass that had consumed a
Chinook salmon in June. We estimated a total of 1,400 Chinook salmon fry were consumed by littoral
predators from February to mid May ..... Based on consumption estimates and expected abundance of
juvenile Chinook salmon, predatory fishes probably consumed less than 10% of the fry that entered the lake
from the Cedar River.
The investigators in this study did not comment on the impacts of overwater structures on the predation rate found
in south Lake Washington.
The following design components will reduce foraging cover and allow more light penetration under the proposed
pier.

I. The pier will be 385 ft2 rather than the 700 ft' allowed for two owners under the guidelines of the RGP-3.
2. The fully grated ramp will only be 3'-9" wide.
3. The fully grated pier section will only be 5'-1 OW' wide.
4. The bottom of the proposed pier will be 18" above OHWL.
5. Only six steel batter pier support piles (8" diameter) will be installed. The most landward piling pair will be
40' from shore.
6. Glu-Iam stringers will be used to allow the longest possible spans between pilings.
C. Interrelated/Interdependent Effects:
Completion of this project will not promote future construction or other activities that would not otherwise occur
without its completion. Therefore, no additional interrelated or interdependent actions that could affect species
regulated under ESA will occur because of this project.
D. Take Analysis:
"Take" is defined as, "to harass, harm, pursue, hunt, shoot, wound, trap, capture, collect or attempt to engage in any
such conduct." The USFWS·further defines "harm" as "significant habitat modification or degradation that results
in death or injury to listed species by significantly impairing behavioral patterns such as breeding, feeding, or
sheltering." It is likely that no "take" will result from this project.
E. Conservation Measures:
In order to minimize any direct effects on the listed species caused by this project, inwater work should take place
between July 16 and December 31. It is requested that overwater work be allowed to take place outside of this work
window. Additional impact reduction and mitigation measures will reduce adverse impacts of the project. They
include:

F. Determination of Effect:
After reviewing the appropriate data and surveys, the effect determinations for the impacts of the project, as
designed, are:
1. Puget Sound chinook -"May affect, not likely to adversely affect"
2. Bull trout -"May affect, not likely to adversely affecf'
3. Puget Sound steelhead -"May affect, not likely to adversely affect"
4. Marbled murrelet -"No effect"
This is the appropriate conclusion when effects on the species and their critical habitat are expected to be beneficial,
discountable or insignificant. Limiting construction work to the approved work window will reduce direct impacts o on the listed species. Shading impacts on the benthic environment will be minimized by the conservation measures
discussed above .

Attachment 3. Essential Fish Habitat Assessment
A. Background
The Magnuson-Stevens Fishery Conservation and Management Act (MSA), as amended by the Sustainable
Fisheries Act of 1996 (Public law 104-267), requires Federal agencies to consult with NMFS on activities that may
adversely affect designated Essential Fish Habitat (EFH) for the relevant species. According to the MSA, EFH
means "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." For the
Pacific West Coast, the Pacific Fisheries Management Council (Council) has designated EFH for federally managed
groundfish (PFMC 1998a), coastal pelagic (PFMC 1998b) and Pacific salmon fisheries (PFMC 1999).
The purpose of the EFH Assessment is to determine the effects of the proposed project on the EFH for the relevant
species and to recommend conservation measures to avoid, minimize or otherwise offset adverse effects on EFH.
B. Identfficatlon of EFH
The designated EFH for groundfish and coastal pelagic species encompasses all waters from the mean high water
line, and upriver extent of saltwater intrusion in river mouths, along the coasts of Washington, Oregon and
California, seaward to the boundary of the U. S. exclusive economic zone (370.4 Ian) (PFMC 1998a, 1998b). The
designated EFH in estuarine and marine areas for Pacific salmon species extends from the nearshore and tidal
submerged environments within state territorial water out to the full extent of the exclusive economic zone (370.4
km) offshore of Washington, Oregon and California north of Point Conception to the Canadian border PFMC,
1999).
Freshwater EFH for Pacific salmon includes all those streams, lakes, ponds, wetlands and other water bodies
currently, or historically accessible to salmon in Washington, Oregon, Idaho and California, except areas upstream
of certain impassable man-made barriers, and longstanding, naturally-impassable barriers.
Chinook salmon and coho salmon are the species with designated EFH that are found in Lake Washington
C. Proposed Action
The details of the proposed project are presented in Project Description section of the attached BElHabitat Data
Report.
D. Effects of the Proposed Action
The effects of this project on designated EFH are likely to be similar to the effects described in detail in the Effects
Analysis section of the attached BElHabitat Data Report. The project is likely to have no permanent, long-term
effects EFH designated for chinook and coho saimon.
E. EFH Conservation Measures
The conservation measures and BMP's mentioned in the attached BElHabitat Data Report will be implemented to
minimize possible adverse effects to EFH.
MS&A Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC Joint-Use Pier Project· 27

•
•
F. Conclusion
The project may have temporary adverse effects on EFH the salmon species, but will not produce long-term adverse
effects on EFH for the above species. The conservation measures and BMP's mentioned in the attached BEfHabitat
Data Report will be implemented to minimize any possible the temporary adverse effects on EFH.

AHachment 4. Assessment of Impacts to Critical Habitat for Puget Sound Chinook
Project description: Construction of a new joint-use pier on Lake Washington in Renton, W A The site is located in
the Lake Washington watershed, 1711001203.
This assessment covers the primary constituent elements (50 CFR Part 226, page 74581-2) determined essential to
the conservation ofPuget Sound Chinook salmon (Oncorhynchus tshawytscha):
(1) Freshwater spawning sites with water quantity and quality conditions and substrate supporting spawning,
incubation, and larval development.
Existing Conditions: There are no suitable freshwater spawning sites at the project location.
(2) Freshwater rearing sites with water quantity and floodplain connectivity to form and maintain physical habitat
conditions and support juvenile growth and mobility; water quality and forage supporting juvenile development;
and natural cover such as shade, submerged and overhanging large wood, log jams and beaver dams, aquatic
vegetation, large rocks and boulders, side channels, and undercut banks.
Existing Conditions: Native vegetation has been planted immediately landward of the bulkhead in conjunction
with the upland development. There is a concrete/sheet pile bulkhead along the shoreline of both properties. No side
channels or undercut banks were noted.
(3) Freshwater migration corridors free of obstruction with water quantity and quality conditions and natural cover
such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, side channels, and
undercut banks supporting juvenile and adult mobility and survival.
Existing Conditions: See (2) above.
(4) Estuarine areas free of obstruction with water quality, water quantity and salinity conditions supportingjuvenile
and adult physiological transitions between fresh-and saltwater; natural cover such as submerged and overhanging
large wood, aquatic vegetation, large rocks and boulders, and side channels, and juvenile and adult forage, including
aquatic invertebrates and fishes, supporting growth and maturation.
Existing Conditions: See (2) above.
(5) Nearshore marine areas free of obstruction with water quality and quantity conditions and forage, including
aquatic invertebrates and fishes, supporting growth and maturation; and natural cover such as submerged and
overhanging large wood, aquatic vegetation, large rocks and boulder and side channels.

Attachment 5.
Assessment of Impacts to Critical Habitat for Coastal -Puget Sound Bull Trout
COE reference: Unknown at this time
Applicant: Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC
The primary constituent elements determined essential to the conservation of bull trout (Salvelinus conjluentus) are:
(1) Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures
from 32 to 72 OF (0 to 22 0c) but are found more frequently in temperatures ranging from 36 to 59 OF (2 to 15 °C).
These temperature ranges may vary depending on bull trout life history stage and form, geography, elevation,
diurnal and seasonal variation, shade, such as that provided by riparian habitat, and local groundwater influence.
Stream reaches that preclude bull trout use are specifically excluded from designation.
Existing Conditions: The project will take place in Lake Washington, a large body of fresh water.
Effects to PCE: The project is not expected to have any influence on the water temperature of Lake Washington.
(2) Complex stream channels with features such as woody debris, side channels, pools, and undercut banks to
provide a variety of depths, velocities, and in stream structures.
Existing Conditions: Project will take place in Lake Washington -not in a stream environment
Effects to PCE: No effect
(3) Substrates of sufficient amount, size and composition to ensure success of egg and embryo overwinter survival,
fry emergence, and young-of-the year and juvenile survival. This should include a minimal amount of fme substrate
less than 0.25 in (0.63 cm) in diameter.
Existing Conditions: No spawning activity at the site
Effects to PCE: No effect
• (4) A natural hydrograph, including peak, high, low, and base flows within historic ranges or, if regulated, currently
operate under a biological opinion that addresses bull trout, or a hydrograph that demonstrates the ability to support
bull trout populations by minimizing daily and day-to-day fluctuations and minimizing departures from the natural
cycle of flow levels corresponding with seasonal variation: This rule finds that reservoirs currently operating under
a biological opinion that addresses bull trout provides management for peEs as currently operated.
Existing Conditions: Project will take place in Lake Washington
Effects to PCE: The project does not involve any alteration in the lake level; therefore it will have no impact on
this peE.
MS&A Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC Joint-Use Pier Project· 31
•
(5) Springs, seeps, groundwater sources, and subsurface water to contribute to water quality and quantity as a cold-
water source.
Existing Conditions: See 4 above
Effects to PCE: This project will have no impact on springs, seeps, groundwater sources or subsurface water
(6) Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing,
overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures
or low flows.
Exi~ting Conditions: Native vegetation has been planted along the site shoreline.
Effects to PCE: The proposed dock will incorporate design components that will decrease negative impacts on
foraging habitat and migratory corridors. The proposed dock will be fully grated and supported by the smallest
number and diameter steel pilings, which will cause minimal physical, biological or water quality impediments.
(See the BFlHabitat Data Report for details).
(7) An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage
fish.
Existing Conditions: Native vegetation has been planted along the site shoreline.
Effects to PCE: See 6 above
(8) Permanent water of sufficient quantity and quality such that normal reproduction, growth and survival are not
inhibited.
Existing Conditions: See 4 above.
Effects to PCE: Pile driving may produce temporary turbidity impacts. These are expected to be short term and are
not expected to have a significant impact on critical habitat. Any debris associated with the project construction
phase will be contained by a silt containment curtain.
Determination of Effect: "No destruction or adverse modification"
Conservation Measures: Conservation measures for this project are seen in the BFlHabitat Data Report .

Assessment Narrative
I. PROJECT LOCATION AND DESCRIPTION
Project Purpose and Location:
The proposed project consists of a joint-use pier and one (I) freestanding boatlift or (2) 10" mooring piles the north
side of pier and (I) freestanding boatlift or (2) 10" steel mooring piles on the south side of pier The proposed pier
would be located along the common property line between two abutting lots, 4119 and 4113 Williams Ave N,
Renton, W A 98056 (jointly the "subject property"), presently owned by Conner Homes at Barbee Mill LLC and
Conner Homes at Barbee Mill LLC, respectively, (jointly the "applicant" for the requested shoreline substantial
development permit). The 4119 Williams Avenue N property owners would have the use of the pier and one boatlift
or the pier and two mooring piles. The 4113 Williams Avenue N property owners would have the use of the pier
and one boatlift or the pier and two mooring piles. The properties are located within the Barbee Mill Community, a
major waterfront subdivision currently under development by Conner Homes at Barbee Mill LLC. The subject
property is located along the eastern shore of Lake Washington in the City of Renton in Section 32, Township 24N,
Range 5E; Latitude: 47.515745"NlLongitude: 122.206114°W. The proposed joint-use pier, boatlifts or mooring
piles would provide moorage and facilitate access to Lake Washington for residents of the subject property and their
guests. The Barbee Mill Community Dock is a day use only structure and does not provide adequate full-time
moorage for waterfront lot owners.
Two bodies of water are adjacent to, or flow through, the Barbee Mill Community: Lake Washington and May
Creek. The subject property is located along Lake Washington, a Shoreline of Statewide Significance as provided in
RMC 4-3-090FI, and a Shoreline of the State under RMC 4-11-190. This Standard Stream or Lake Study is
prepared in accordance with the requirements ofRMC 4-8-1200 with respect to the Lake Washington shoreline of
the subject property and the 100' of abutting lakeshore lots both to the north and to the south of the subject property
(the "study area"). May Creek, a Shoreline of the State (RMC 4-3-090F2), flows through the Barbee Mill
Community. The distance from the closest point (the southeast property line of Lot 38) to the OHWL of May Creek
is 195'. The project location itself is 130' from the southeast property line of Lot 38. Therefore, it is 325' from the
project location to the OHWM of May Creek. The community May Creek open space (a riparian buffer), parking
spaces and a street cover the area between the southeastern corner of the subject property and May Creek.
Project Description:
• The Barbee Mill community is being developed by Conner Homes at Barbee Mill LLC on the approximately 22
.acre site of the former Barbee Mill Company lumber mill. Upon completion, the Barbee Mill community will have
114 multi-story paired homes, a pond, walking trails and lakefront open space for the use of residel)ts. Lots 23
through 48 are lakefront lots; the subject property is situated on lots 37 and 38. To restore the former industrial site
to a parcel suitable for a residential waterfront subdivision, the mill buildings were demolished; fill soils were
removed from behind the bulkhead; asphalt paving, a pier, the wooden bulkhead and piling associated with the mill
operation were removed; and extensive shoreline restoration was completed. The subject property is located south
of, and was not included in, this extensive remediation. The southern 18 feet of 4113 is a rock bulkhead and the
remaining shoreline of 4113 and all of 4119 is a sheet pile bulkhead with a concrete cap. Both properties shoreline
total 78' long. The substrate immediately waterward of the bulkhead consists oflarge and small cobble.
i·
I
Under the proposed project plan, ajoint-use pier would be constructed on the common property line. The pier
would be oriented to keep all structures and moorage within the side property setbacks of each property in
compliance with all City of Renton zoning and municipal codes. (Figure 2) The proposed joint-use pier project
would provide convenient Lake Washington access and moorage capabilities from each of the subject property lots.
MS&A Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC Joint-Use Pier Project· 3
Residents and their guests would have use of the pier for swimming, fishing, water skiing and any number of other
water sports and activities. The boatlifts or mooring piles would provide safe and adequate moorage. The applicant
considered a number of factors in detennining the location of the proposed pier, most importantly the lower
environmental impact of a joint-use structure over individual single-property use piers. In establishing design
parameters for the proposed project, the applicant required that none of the proposed structures interfere with the
general public's use and enjoyment of Lake Washington, that no structure pose a navigation hazard to boaters, and
that no structure interfere with the USe of existing or future neighboring docks or piers.
2. LAKE AND STREAM CLASSIFICATIONS
As a Shoreline of Statewide Significance (RMC 4-3-090FI), Lake Washington is included in the definition ofa
Shoreline ofthe State (RMC 4-11-190). Lake Washington is a Class I lake as it is a perennial salmonid-bearing
body of water classified as a Shoreline of the State (RMC 4-11-190S I). May Creek is an important salmonid stream
that is classified by the City of Renton and the State of Washington as Class I waters and included within the
defmition ofa Shoreline of the State (RMC 4-3-090F2).
3. SHORELINE RESTORATION AND OHW MARK
Shoreline Restoration:
Prior to restoration of the beach in conjunction with vacation of the land, the Lake Washington shoreline north of
the subject property was heavily bulkheaded, back-filled and covered with impervious asphalt paving; numerous
piling and substantial quantities of concrete rubble and other shoreline debris were on the site. Pursuant to the
general development site remediation, upland and in-water structures including the timber bulkhead and piling were
removed, shoreline rubble was removed, fill soil was excavated to subgrade elevations, toe rock and a temporary
quarry spall erosion control benn were installed, and sand, gravel and rock materials were used to construct a beach
to mimic natural conditions. Although the area of extensive remediation did not encompass the subject property, a
planting buffer of native vegetation was installed along all the lakefront lots, including the subject property, to
environmentally and functionally enhance the entire development shoreline. There would be no clearing or grading
associated with the proposed joint-use pier, boatlifts or mooring piles.
OHWMark:
The Ordinary High Water (OHW) mark for Lake Washington is the line of mean high water (RMC 4-11-150
Definitions 0). The Lake Washington water depth is controlled by the Army Corps of Engineers at the Hiram M.
Chittenden Locks and is at 21.8' oflake elevation. In the course ofthe Barbee Mill Beach Restoration site
remediation, pennanent toe rock was installed along the OHW line. As of March 20, 2007, the date the SCUBA
survey was conducted for purposes of identifying flora, fauna, substrate types and other qualitative infonnation
relative to the Biological Evaluation prepared for the previous community dock project, coir rolls were located
along the OHW line within the remediation area. The May Creek OHW mark is the mean high water line of the
stream (RMC 4-11-150 Definition 0).
4. VEGETATIVE COVER OF THE SITE
The study area includes no wetland or flood hazard areas; it does include Lake Washington riparian areas. Prior to
the Barbee Mill Beach Restoration project, riparian vegetation was found to be generally absent within the study
area as the shoreline behind the bulkhead was paved. In unpaved areas, vegetation noted included Juncus effusus
(soft rush) and Iris pseudocaris (a non-native iris). The upland redevelopment required extensive regrading and
clearing; a mitigation planting plan was agreed upon that includes planting along the Lake Washington shoreline. In
accordance with this mitigation plan, plantings on the subject property have been installed. In conjunction with
construction of the proposed joint-use pier, additional native plants, shrubs and/or trees will be planted as specified
in applications to, and as approved by, the Washington State Department ofFish and Wildlife and the U. S. Army
Corps of Engineers.
The following species are included in the preliminary plant list for the shoreline buffer zone:

In the course of the March 20, 2007, SCUBA survey for the conununity dock project, Myriophyllum spicatum
(Eurasion Milfoil), an invasive nonnative plant, was found along all transects. No planting is proposed below the
OHW line.
5. ECOLOGICAL FUNCTIONS OF LAKE WASHINGTON ALONG STUDY AREA
Until relatively recently, the industrial structures and use of the site limited the ecological functions that would
otherwise have been provided by Lake Washington and its adjacent riparian area. As a result of the extensive
general site restomtion work completed north of the subject property, including removal of the wooden bulkhead,
large pier and numerous pilings, excavation of fill soil from behind the bulkhead, and reconstruction of the beach to
mimic its natural state, the ecological functions of the portion of the lake within the study area should be greatly
enhanced. Recently planted riparian vegetation and additional plantings in conjunction with the proposed project
will further assist in restoring the ecological functions of Lake Washington. Much of this new vegetation will be
overhanging, providing shade and predator protection for fish and aquatic invertebmtes. The newly planted riparian
vegetation will add significant organic matter to the lake substrate in the form of leaves and woody debris that fall
and wash in; an additional source of food, shelter and shade for aquatic invertebrates and fish. This increased
vegetation will also provide food and shelter for terrestrial insects, and in tum provide an additional food source for
birds and animals that feed upon them. The addition of riparian vegetation to this formerly near-barren site should
also help water quality by filtering pollutants, removing nutrients and reducing sediments in any runoff from the
adjacent upland development. The smaller design of the proposed project as compared to the structures removed,
together with increased overhanging vegetation, may facilitate the migration of juvenile salmon.
6. FISH OR WILDLIFE USE OF AREA
Birds:
Birds observed on or near the site include hawks, herons, eagles, quail, osprey, cormorants and songbirds. Before
the mill structures were demolished, an osprey nest was successfully relocated from the top of the old mill sawdust
collector to a platform built on a 25' pole over the water not far from the original nest site. The osprey have accepted
the new nest and a video camera records their activities for viewing over the Internet. Although the bald eagle is no
MS&A Conner Homes at Barbee Mill LLC/Conner Homes at Barbee Mill LLC Joint-Use Pier Project 0 5
o
•
•
longer on the list of threatened or endangered species under the Endangered Species Act (ESA), bald eagles
continue to be protected by the Bald and Golden Eagles Protection Act and the Migratory Bird Treaty Act, and are
protected as a "sensitive species" within the state of Washington (WAC 232-12-011). The only eagle nests observed
near the project site are two nests approximately 0.65 mile from the site on the opposite shore.
Mammals:
The only wild mammals reported as observed in the area are deer.
Fish:
Salmon ids observed at the site include salmon and trout. Salmonids known to be present in southern Lake
Washington include Puget Sound chinook salmon, coho salmon, sockeye salmon, steelhead trout, bull trout and
cutthroat trout. Puget Sound chinook, Puget Sound steelhead and bull trout are all listed as threatened under the
ESA. Other fish observed at the site include bass, black crappie, bluegill, pumpkinseed sunfish, tench and yellow
perch. The shoreline remediation was designed to be consistent with Water Resource Inventory Area (WRIA) 8
Conservation Plan recommendations. As a result ofthe remediation, shoreline that was previously unsuitable habitat
for fish and other aquatic life due to extensive shoreline modifications and industrial use of the site has been
restored. The restored gravel substrate and gently sloping bottom should provide favorable habitat for winter rearing
of salmon fry. The new gravel substrate to the north and the existing cobble on the subject property should be
suitable habitat for benthic invertebrates which would likely attract juvenile salmonids.
7. MEASURES TO PROTECT TREES AND VEGETATION
At the present time, the study area has no living woody plant with a trunk six inches or greater in diameter or any
other plant falling within the definition of "Tree" in RMC 4-11-200. This is likely because of the prior asphalt
paving over, and industrial use of, the area and subsequent excavation and regrading in accordance with the
approved upland development plan. The proposed joint-use pier area has been landscaped pursuant to the general
development planting plan. Additional native plants, shrubs and/or trees will be installed in accordance with state
and federal project permits. Trees planted in accordance with all landscaping plans will likely have trunks less than
six inches in diameter at the time of planting .
