Washington Biological Evaluation 2
1.0 Propos d Action
This Biologica Evaluation has been submitted on behalf of Suzanne Washington at the
request of the Seattle District United States Army Corps of Engineers to comply with
Endangered Species Act(ESA)regulations regarding shoreline development. The
proposed action on their Lake Cushman property is the installation of an approximately
(approx.) 19-f of wood bulkhead with inset shoreline access steps and the replacement of
an existing pie ,ramp, and float with a new pier, ladder, and float cradle. An existing EZ-
Dock float(m de of polyethylene plastic)with be re-used(and repositioned).
Mitigation for the proposed project will include downsizing the footprint of the
replacement o erwater structure,which will result in a reduction of overwater coverage
of 140 square feet(sf). The replacement pier and will be grated(the existing is ungrated)
and untreated Alaska yellow cedar will replace existing treated lumber structures.
1.1Backg ound
The proposec project site is located in Mason County at 2190 West Cushman Ridge
Road,Hoods ort Washington(Attachment 1).The Mason County tax parcel number the
is
42331-50-02 09. The property is located in Section 30,Township 23N,
RangeWestern Meridian. The latitude is 47.45821 north, and the longitude is -123.23501 west.
The proposed project site is on Lake Cushman in the Skokomish/Dosewallips Water
Resource InN entory Area 16 (WRIA 16) in Mason County. Lake Cushman is regulated
under the M son County Shoreline Master Program and the Mason County Resource
Ordinance as a Fish and Wildlife Habitat Conservation Area. The Shoreline Management
Act of 1971 designated Lake Cushman as a Shoreline of Statewide Significance. In
addition,Lake Cushman is regulated by Tacoma Public Utilities(aka Tacoma Power),
which has designated Shoreline Management Classification(SMC)zones. The proposed
project site is located in an SMC zone classified as"A."Tacoma Power defines the "A"
management classification as shoreline areas with no known significant
environmental/cultural resources or associated resource management goals precluding
existing or future shoreline uses;this classification acknowledges existing private uses
and anticipates potential future private and light commercial shoreline uses (Kleinschmidt
2012).
The propos d project site is located in a rural area on an approx. 6.6 acre lot with approx.
300 feet of shoreline,which supports a single-family residence located approx. one
hundred feet(100')horizontally and forty feet(40')vertically from the shoreline
of Lake
a wood
Cushman. Existing shoreline appurtenances (Attachments 2, 4, 5, 6, & 7)
include ramp (40 s , an aluminum ramp (30 sf), a wood pier(260 sf), and an EZ-Dock float
(97.5 sf).

1.2 Project Need and Objectives
The bluff toe at the site exhibits erosion damage that is common to the Lake Cushman
shoreline. There are three primary causes of this erosion and concomitant shoreline
instability:
• The seasonal raising and lowering of Lake Cushman, a reservoir with two
functioning dams.
• The lake's unique landscape features, including a steep, unnatural lakebed
topography that lacks a shallow foreshore to diminish wave energy generated by
strong prevailing winds and approx. eight miles of fetch.
• A steep terrestrial shoreline that receives an average of approx. 100 inches of
rainfall per year.
The west side of Lake Cushman is also subjected to damaging surface flows due to clear
cut logging on the steep slopes above the shoreline. The applicant's property features
heavily vegetated steep slopes and an extremely steep lakebed adjacent to the shoreline.
Bluff toe erosion has caused several large trees to fall onto the shoreline at the site
(Attachment 8). Due to the existing bluff toe erosion and the potential for further slope
instability in the vicinity of shoreline access at the site, shoreline protection in the form of
a wood bulkhead is proposed. The bulkhead will be the minimal length necessary to
protect shoreline access to existing and proposed overwater structures.
Additionally, the applicants' existing pier and access ramp is old and in need of repair
and replacement. The applicants wish to extend the life of the existing overwater
structures, while at the same time making them safer for both humans and the
environment. Therefore, the project objective is to install a new bulkhead of minimal size
that is long enough to protect shoreline access and renovate an existing overwater structure, all-the-while avoiding or minimizing impacts to ESA-listed species and
improving shoreline habitat at the site.
2.0 Project Description
As per the engineered design by Steve Morta, approx. nineteen feet (19')of post and
plank wood bulkhead will be installed along the bluff toe at an approx. lakebed elevation
of between 740 and 742 feet. The proposed bulkhead will be an average above grade
height of four(4) feet. The bulkhead will be constructed of six by six inch (6"x 6")
Alaska yellow cedar posts, two by twelve-foot 2' x 12'
)yellow cedar planks, and
galvanized hardware. Shoreline access steps constructed of Alaska yellow cedar will be
inset into the bulkhead near the center.
The existing overwater structure will be removed, with the exception of the existing five
by approx. nineteen-foot(5' x 19.5')EZ Dock float, and replaced with a six by thirty-
three-foot(6' x 33')pier and a manufactured vertical ladder. The pier will be attached to
Washington Biological Evaluation
4
Y
the bulkhead with metal hardware and supported by six(6) six by six inch (6"x 6")
Alaska yellow cedar posts. The existing float will be repositioned. Two (2) steel I-beams
will be field welded to eight(8),two-inch (2") steel pipes set in concrete footings to
create a float crib that will give the float a minimum of 18 inches of lakebed clearance
during the low water season. The vertical ladder will provide access between the pier and
float. All concrete for the bulkhead, pier, and float will be hand-mixed per engineered
drawings and poured in place.
The pier and fl at will be constructed of galvanized steel or aluminum hardware, and
Alaska yellow cedar posts,joists, decking, and trim, or composite decking and trim. The
decking of the pier and float will have grating installed(a percentminimum fifty coverage
with 60 percent light passage, as required by the WDFW). The total o erwat
at the site will be 295.5 square feet, a reduction of 140 sf from the existing 435.5 square
feet.
All piling hot s will be three feet(3') deep and approx. eighteen inches (18')wide, and
filled with concrete.No pressure treated lumber will be used in this project. All overwater
structures wit be grated with ThruFlow decking
kinand are panels,which
are
made of reinforced
polypropylen , contain no toxic preservatives,
A circular saw and various hand tools will be used throughout the proposed project.
Workers, equipment,debris, and materials will be transported to the site either by boat or
by cars or trucks. Geo-textile fabric will be spread over the dry lakebed before
commencem nt of project construction in order to contain any manmade construction
debris. At the completion of construction,the geo-textile fabric will be removed from the
shoreline at tie site, along with all construction debris and other existing manmade
debris. All d bris will be disposed of at a licensed landfill or other licensed disposal site.
2.1 Project Activities
Demolitioll of the Pier & Ramps
The existing,pier,pier access ramp, and float ramp will be disassembled and removed
from the site. Approximately twelve existing pilings and associated concrete footings will
be removed. The footings will be excavated using hand tools and the holes refilled with
the excavat d lakebed sediments.
Excavation of the Bulkhead, Pier, &Float Cradle Post/Pipe Footings
Due to the difficulty of accessing the site with heavy machinery, it will be necessary to
manually xcavate substrate material for the bulkhead posts and the piling footings. The
bulkhead z nd pier post holes (five and six,respectively) and float cradle pipe holes
5
Washingt n Biological Evaluation
i y
(eight)will be approx. three feet deep and eighteen inches wide. A small amount of
excavated substrate material will be stockpiled on the shoreline and will later be spread
along the new toe to fill in any depressions left by the removal of the forms. The majority
of the excavated material will be removed from the lakebed at the site, as per Tacoma
Power's rules and regulations.
Pouring of the Bulkhead Posts and Pier& Float Pilings
Concrete for the bulkhead and pier posts and float cradle footings will be poured at the
same time. All concrete for the bulkhead,pier, and float will be hand-mixed and poured
in place. Before concrete is poured, the yellow cedar posts and steel pipe will be
positioned in the post/pipe holes, then the concrete will be poured and allowed to cure.
Pier Construction & Float Repositioning
The pier replacement will be constructed of Alaska yellow cedar, galvanized steel or
stainless steel hardware, and yellow cedar or composite decking and trim. The existing
float will be repositioned using manual labor. The new vertical ladder will be installed
between the pier and the float, using galvanized hardware.At the completion of
construction, the geo-textile fabric will be removed from the shoreline at the site, along
with all construction debris and other existing manmade debris. All debris will be
disposed of at a licensed landfill or other licensed disposal site.
2.2 Timing
Work will be completed over an approx. fourteen 14 day
dayliht
working hours normal to a rural neighborhood. Work will my take place when the water
level of Lake Cushman is low, which is generally between October and April.
2.3 Conservation Measures
1. No construction to occur unless Lake Cushman's waters are low.
2. No pressure treated lumber will be used in this project.
3. Overwater coverage at the site to be reduced by 140 square feet.
4. Construction to take place as per the HPA provisions from the Washington
Department of Fish and Wildlife.

5. The decking of the pier and float will have grating installed(fifty-four percent
total {i.e. four percent greater than required by WDFW I with 60 percent light
pasE age).
6. Previously discussed BMPs to be strictly adhered to.
2.4 Best Management Practices
In order tomaintain the present water quality of Lake Cushman during project
construction, est Management Practices (BMPs)will be implemented. BMPs are
defined as ph sical, structural, and/or managerial practices that prevent or reduce the
pollution of m ater(WDOE). The following source control BMPs, which are detailed in
the WDOE's 5tormwater Management Prevention (2012)Manualfor stern will beampl�mented for long-term

protection of water quality at the site:
BMP C101: Preserving Natural Vegetation
Wherever practical, native vegetation shall be preserved to reduce erosion.Natural
vegetationshould be preserved slopes,
m wooded a eas,and intermittent
watercourse or swales, and on bu lding sites
BMP C154: Concrete Washout Area
Purpose:Prevent or reduce the discharge of pollutants to stormwater from concrete waste
by conducting washout off-site, or performing on-site washout in a designated area to
prevent pollutants from entering surface waters or ground water.
Conditions of Use: Concrete washout area best management practices are implemented
on construction projects where:
•Concr to is used as a construction material.
•It is not possible to dispose of all concrete wastewater and washout off-site(ready
mix plant, etc.).
*Concrete trucks,pumpers, or other concrete coated equipment are washed on-site.
•Note: If less than 10 concrete trucks or pumpers need to be washed out on-site,the
wash water may be disposed of in a formed area awaiting concrete or an upland
dis)osal site where it will not contaminate surface or ground water. The upland
dis)osal site shall be at least 50 feet from sensitive areas such as storm drains,
open ditches, or water bodies, including wetlands.
•A ter orary washout facility shall be constructed on-site or the concrete truck will be
washed out off-site.
7
tion
Washington Biological Evalua
•When temporary concrete washout facilities are no longer required for the work, the
hardened concrete, slurries and liquids shall be removed and properly disposed of.
*Materials used to construct temporary concrete washout facilities shall be removed from
the site of the work and disposed of or recycled.
BMP C151: Concrete Handling
Purpose: Concrete work can generate process water and slurry that contain fine particles
and high pH, both of which can violate water quality standards in the receiving water.
Concrete spillage or concrete discharge to surface waters of the State is prohibited. Use
this BMP to minimize and eliminate concrete, concrete process water, and concrete slurry
from entering waters of the state.
Conditions of Use:Any time concrete is used, utilize these management practices.
•Wash out concrete truck chutes,pumps, and internals into formed areas only. Assure
that washout of concrete trucks is performed offsite or in designated concrete
washout areas. DO not wash out concrete trucks onto the ground, or into storm
drains, open ditches, streets, or streams.
•Return unused concrete remaining in the truck and pump to the originating batch
plant for recycling. Do not dump excess concrete on site, except in designated
concrete washout areas.
•Wash off hand tools including, but not limited to, screeds, shovels, rakes, floats, and
trowels into formed areas only.
•Wash equipment difficult to move in areas that do not directly drain to natural or
constructed stormwater conveyances.
*Do not allow washdown from areas, such as concrete aggregate driveways, to drain
directly to natural or constructed stormwater conveyances (or Puget Sound).
*Contain washwater and leftover product in a lined container when no formed areas
are available. Dispose of contained concrete in a manner that does not violate
ground water or surface water quality standards.
eAlways use forms or solid barriers for concrete pours, such a pilings, within 15-feet
of surface waters.
BMP C233: Silt Fence
Silt fence may be used downslope of all disturbed areas. Silt fence shall prevent soil
carried by runoff water from going beneath, through, or over the top of the silt fence but
shall allow the water to pass through the fence.
The following additional BMP shall be used to insure that water quality is not
degraded during and after construction:

1. Equipment will be cleaned and checked for leaks, offsite and daily,before
commencing work.
In addition,the following Spill Prevention Control measures will also be followed: 1)the
applicant will supply the site with a portable bathroom or allow workers access to an
onsite bathroom so that solid or liquid waste will not become a source of stormwater
pollution. 2)The applicant will be responsible for alerting the appropriate authorities in
the event of a iazardous spill. 3) The applicant will have a spill kit and be able to
perform basic control,containment, and/or confinement operations within the capabilities
of the resources and personnel protective equipment available. In other words, small
spills, such as paint or oil,will be promptly and fully collected and disposed of at a
suitable disposal site. In the event of a significant spill, a fish kill, and/or if fish are
observed in distress the Washington State Department of Ecology(800.258.5990) and the
Washington State Department of Fish and Wildlife's Area Habitat Biologist, Joshua
Benton(360. 02.0364), will be notified immediately.
3.0 Actio Area
The action area is located on the shoreline of Lake Cushman at the proposed project site.
Besides the p-oposed project location,the action area includes the surrounding area
within a designated distance from the site in order to account for construction impacts
that may affect species listed under the Endangered Species Act by the U.S. Fish and
Wildlife Service and the National Marine Fisheries Service as either endangered or
threatened. T e limits of the action area are based upon the geographic extent(in both
aquatic and terrestrial environments) of the physical, chemical, and biological effects
resulting from the proposed action, including direct and indirect effects, as well as effects
of interrelated and interdependent activities (WSDOT 2010). Turbidity and noise are
expected to e the most detrimental project effects. Because work will occur when Lake
Cushman is lowered,project turbidity is expected to be no greater than turbidity that is
common tot e area during heavy rains,when various ephemeral and perennial streams
and the nort fork of the Skokomish River discharge sediment laden water into Lake
Cushman. It is probable that the project's distance from the lake's lowered shoreline will
be great enough that disturbed sediments will disperse gradually(via precipitation) over
the exposed lakebed without ever reaching water until the lake is raised. Additionally,the
excavation required to remove existing small pilings is expected to be minimal.
Therefore,terrestrial noise is expected to be the most far-reaching effect from the
proposed pr ject.
The action rea for terrestrial noise effects is based upon an ambient sound level of 40
dBA for an area with a population of less than 100 people per mile (WSDOT 2010). In
addition,the Olympic National Forest programmatic biological assessment uses an
estimated ambient level of 40 dBA for undisturbed forested areas (USDI 2003).Noise
frequency and levels for the repair of the existing pier, the construction of the
9
Washington Biological Evaluation
replacement float(if it is conducted on site), and the demolition of the pier frame and
deck,the float, and jet ski ramp is expected to be short term and moderate, as the
contractor will be using hand tools such as a skill saw. The sawing of the lumber is
expected to produce the proposed project's maximum noise level. The noise level of a
circular saw at fifty feet was determined as follows: The noise level at 50 feet from a
chain saw is 84 dBA (WSDOT 2014). The noise level of a chain saw at three feet is 110
dBA, while a circular saw is 100 dBA. Assuming that a chain saw is between approx.
five and ten percent noisier than a circular saw, the noise level of a circular saw at fifty
feet was assigned 79 dBA.
To determine the distance that the proposed project's maximum point source construction
noise will travel before it attenuates to the ambient sound level; the following Practical
Spreading Loss Model equation was used:
D=Do * 10((Construction Noise—Ambient Sound Level in dBA)/a) Where D =the
distance from the noise &Do=the reference measurement distance of 50'.
Average construction noise from the proposed project will travel approx. 3,970 feet over
hard site conditions(Lake Cushman)and 1,656 feet over soft site conditions (forested
areas)before it(the noise) attenuates to the ambient sound level. Therefore,the extent of
the action area is 3,970 feet or 0.75 mi. over the lake's surface and 1,656 feet or 0.31 mi.
inland from the proposed project site and adjacent shorelines (Attachment 1).
In addition,the action area includes one fish bearing stream (approx. 0.7 mi. to the south)
and seven unnamed ephemeral streams located within approx. 0.75 mi. north and south of
the project site. There are no streams adjacent to the project work area.
4.0 ESA Species and Habitat Information
In the proposed project area,there are five species listed under the Endangered Species
Act by the U.S. Fish and Wildlife Service (USFWS)as either threatened or endangered.
The bull trout(Salvelinus confluentus), marbled murrelet(Brachyramphus marmoratus),
northern spotted owl (Stridex occidentalis), streaked horned lark(Eremophila alpestris
strigata), and yellow-billed cuckoo (Coccyzus americanus)are listed as threatened and
critical habitat has been designated for the former four species. The project area is located
on Lake Cushman, which has been designated critical habitat for the bull trout. Two other
species in the project area are listed as proposed. The fisher(Mantes pennanti) is listed as
proposed threatened, and the Dolly Varden (Salvelinus malma) is listed as proposed
under the ESA "similarity of appearance"provision.
In the proposed project area, there is one species listed under the Endangered Species Act
by the National Marine Fisheries Service (NMFS) as either threatened, endangered, or a
candidate species. The Puget Sound Chinook salmon(Oncorhynchus tshawytscha) is
listed as threatened and critical habitat has been designated. Lake Cushman is a historical
Washington Biological Evaluation
10
watershed of th Chinook that has been anthropogenically blocked; however, it has been
designated critical habitat.
The Washington Department of Fish and Wildlife (WDFW) GIS maps reveal the
documented pr sence of two other species of salmonids on the State's Priority Habitat
and Species lis within the action area: Kokanee (Oncorhynchus nerka) and the Puget
Sound/Coastal cutthroat trout(Oncorhynchus clarki clarki). The presence of these two
species has been documented in Lake Cushman. WDFW data reveals that Lake Cushman
was stocked w th 23,896 cutthroat trout in 2005 and 205,800 Kokanee (landlocked
sockeye salmo ) in 2004. A WDFW biologist reported that other species that inhabit the
lake include rainbow trout(Oncorhynchus mykiss) and non-native largemouth bass
(Micropterus lmoides).
Additionally, Tacoma Power is presently working in association with the Skokomish
Tribe and the WDFW to reestablish migrating salmonid runs in the North fork of the
Skokomish River. The North Fork Skokomish Powerhouse and Fish Facility has recently
been completed. This facility collects adult fish at the base of Cushman Dam No. 2 and
transports them to the top of the dam for sorting. It also provides sorting facilities for
juvenile fish and transports them to the base of the dam for release into the river. The fry
will be released in Lake Cushman, and smolts will be collected and released into the
lower North Fork Skokomish River. Returning adult sockeye will eventually be collected
at the base of Cushman Dam No. 2. Two new hatcheries are also under construction, one
on the Hood anal at Potlatch for sockeye,the other on Lake Kokanee for Chinook,
coho, and ste lhead. Hatchery construction is planned to be complete in 2015 (Tacoma
Public Utilities 2015).
4.1 ESA Listed Species
BULL TROUT
Bull trout are members of the char subgroup of the salmon family and are native to the
Pacific Northwest and western Canada. Water temperature above 15 degrees Celsius is
believed to limit bull trout distribution, as eggs and juveniles require extremely cold
water for survival. Bull trout are also vulnerable to degraded stream habitat, poor water
quality, dam and other stream blocking structures, and predation by non-native fish.
Critical habi at includes Lake Cushman and the upper North Fork of the Skokomish
River(70 FR 56304). Critical Habitat in the former includes spawning and rearing
habitat,while the latter provides rearing,foraging, and migration habitat, so it is expected
that bull trout may be found in the action area of the proposed project site.
MARBLED MURRELET
A small, diving seabird in the family Alcidae,the marbled murrelet forages for small fish
and invertebrates almost exclusively in nearshore marine waters,while nesting inland in
Washington Biological Evaluation
11
old-growth or mature conifer forests. Threats include loss of habitat,predation, gill-net
fishing operations, oil spills, marine pollution, and disease. The USFWS assembled a
team of scientists in October 2011 to investigate causes for the continued decline in
murrelet populations. The outcome of these discussions listed many factors, chiefly loss
of potential nesting habitat as the main reason for hindrance of population recovery goals
(WDFW 2012).
Potential nest trees are coniferous trees within 55 mi (88.5 km) of marine waters that
support at least one 4-inch (10.2-cm) diameter platform located at least 33 feet(10
meters)above the ground, with horizontal and vertical cover(USFWS 2012). If a tree or
forested area does not support these habitat features, it is "extremely unlikely"to support
a murrelet nest(USFWS 2012).Nest success is influenced by forest structure,the spatial
mix of habitat and non-habitat, human disturbance,prey availability, and marine foraging
conditions. Human disturbance can lead to higher predation levels by Steller's and gray
jays, crows, ravens, and other species that seek human-related foods and refuse at high-
use recreational areas (Peery et al. 2004, Marzluff and Neatherlin 2006).
Critical habitat for the marbled murrelet, which was designated in May of 1996 and
revised in October of 2011, but it is not located within the proposed project's action area.
In addition, the proposed project will not result in excessive noise or the loss of any trees
or other vegetation, and water quality at the site will be minimally impacted.
NOR THERN SPO TTED OWL
The Northern Spotted Owl is one of the largest owls in North America, and the average
adult female is approx. 18 inches tall with a 48-inch wingspan. Northern spotted owls are
strictly nocturnal, and require old-growth forests with multi-layered canopies of trees,
including large trees with broken tops, deformed limbs, and large holes and cavities to
nest in. The Northern spotted owl is very territorial and intolerant of habitat disturbance,
and a pair requires a large amount of forest for hunting and nesting. Habitat loss has
occurred as a result of forest conversion, timber harvest, fire, windthrow, insect outbreak
and disease (WDFW 2012).
The USFWS designated revised critical habitat for the northern spotted owl under the
Endangered Species Act. In total, approx. 9,577,969 acres (ac) (3,876,064 hectares (ha))
in 11 units and 60 subunits in California, Oregon, and Washington fall within the
boundaries of the 2 critical habitat designations. The action area does not include
designated critical habitat for the Northern spotted owl. In addition, due to the close
proximity of human habitation, it is unlikely that any Northern spotted owls may be
found in the action area. Also, the proposed project will not result in the loss of any trees
or shrubs.
Washington Biological Evaluation 12
STREAKED HORNED LARK
Horned larks are birds that utilize wide open spaces with no trees and few or no shrubs.
The streaked homed lark nests on the ground in sparsely vegetated sites dominated by
grasses and shr bs. Historically this type of habitat was found in prairies in western
Oregon and Washington, in dune habitats along the coast of Washington, on the sandy
beaches and spits along the Columbia and Willamette Rivers, and in grasslands, estuaries,
and sandy beaches in British Columbia(WDFW 2012). Today the streaked horned lark
nests in a broad range of habitats, including native prairies, coastal dunes, fallow and
active agricultural fields,wetland mudflats, sparsely-vegetated edges of grass fields,
recently plante I Christmas tree farms with extensive bare ground, moderately-to heavily-
grazed pasture , gravel roads or gravel shoulders of lightly-traveled roads, airports, and
dredge deposition sites in the lower Columbia River(WDFW 2012).
It is expected that the action area contains unsuitable habitat for the streaked horned lark.
YELLOW-BILLED CUCKOO
The yellow-billed cuckoo (Coccyzus americanus) is a neotropical migrant bird that
winters in So th America and breeds in western North America. The yellow-billed
cuckoo is insectivorous and lives in riparian woodlands (USFWS 2014). Reports of
individual cuckoos have been very rare in recent decades,with only three known reports
since 2000,these being near Lind(Adams Co.) in 2001,near Eureka(Walla Walla Co.)
in June 2007, and from Little Pend Oreille National Wildlife Refuge (Stevens Co.) in
June 2012. Habitat loss and pesticide use are thought to be two of the main causes for the
precipitous decline of western yellow-billed cuckoos.Agriculture, grazing,reservoir
construction, flood control,urbanization, and other factors across the West have caused
the large-scat loss and degradation of lowland riparian forest,which is the cuckoo's
primary habitat.
It is expected that the action area contains unsuitable habitat for the yellow-billed cuckoo.
CHINOOK SALMON
Chinook salmon in Lake Cushman are a land-locked population that originated from
anadromous fish, although loss of genetic variation makes it difficult to determine
whether the are descended from historical Hood Canal populations or introduced
hatchery fish (NOAA 2006). Lake Cushman Chinook are genetically different, smaller in
size (and presumably less fecund)than their anadromous counterparts(Myers et at.
1998). On Jan. 12,2009,Tacoma Power,the Skokomish Tribal Nation and state and federal
agencies signed a settlement agreement that resolved a$5.8 billion damages claim and
long_standin g disputes over the terms of a long-term license for Cushman Hydroelectric
Project. Tacoma Power has proposed to introduce sockeye and spring Chinook and
enhance the existing winter steelhead and coho populations in the North Fork in
cooperation with the WDFW and the Skokomish Tribe (Tacoma Public Utilities 2014). In
13
Washington Biological Evaluation
addition, Tacoma Power will annually release up to 100,000 rainbow trout for sport
harvest(TPU 2014).
Lake Cushman has been designated Critical habitat, and the site provides rearing,
foraging, and migration habitat, so it is expected that adult and/or juvenile Chinook
salmon may be found in the action area.
5.0 Environmental Baseline Conditions
5.1 Action Area
The environmental baseline represents the existing set of conditions,to which the effects
of the proposed action are then added. The environmental baseline is defined as "the past
and present impacts of all Federal, state, and private actions and other human activities in
the action area, the anticipated impacts of all proposed Federal projects in the action area
that have already undergone formal or informal section 7 consultation, and the impact of
state or private actions which are contemporaneous with the consultation process" (50
CFR 402.02).
The proposed project site is in WRIA 16 (Water Resource Inventory Area), on Lake
Cushman in Mason County. The majority of the fresh and marine waterbodies in WRIA
16 suffer from water quality issues; however Lake Cushman is not listed on the state's
2012 Water Quality 303(d) list of impaired waterbodies for any parameters. Two
waterbodies in the Skokomish watershed,the South Fork of the Skokomish River and
Lebar Creek are listed for the parameter of temperature (high). The current
Environmental Protection Agency(EPA) approved Water Quality Assessment data for
Washington State reveals that tissue samples from fish (various species, including
salmonids)collected in Lake Cushman were tested for twenty(20)pesticides and other
pollutants, including mercury,PCBs, DDT, Toxaphene, Lindane, Dieldrin, and
Hexachlorobenzene. The twenty tested parameters (all)met the FTEC (fish tissue
equivalent concentration) and received Category 1 water quality listings. The FTEC is the
concentration of a contaminant in fish tissue that Washington equates to the National
Toxics Rule water quality criterion for the protection of human health (WDOE 2016).
Fish tissue data from the most recent year showed that the FTEC was met; therefore the
Assessment Unit meets the requirements for a Category 1 determination (WDOE 2016).
The water quality criterion for a Category 1 water quality listing is defined by the
Washington Department of Ecology(WDOE), as:
Meets tested standards for clean waters:placement in this category does not necessarily
mean that a water body is free of all pollutants. Most water quality monitoring is
designed to detect a specific array of pollutants, so placement in this category means that
the water body met standards for all the pollutants for which it was tested.
The proposed project site is located on the west side of Lake Cushman in an extremely
rural neighborhood on a lot with approx. 300 feet of shoreline frontage. Neighboring
Washington Biological Evaluation 14
parcels support recreational cabins,piers, floats, and a small amount of bulkheaded
shoreline. Forested land in the vicinity of Lake Cushman has been logged heavily.
Erosion impacts from surface flows have been particularly damaging in the logged areas
above the lake's west shore.
Before the com letion of two dams in 1926 and 1930, Lake Cushman was a natural
oligotrophic la e with a mean depth of 200 feet.Now Lake Cushman is 4,010-acre water
body in the Olympic National Forest,having been altered in size to accommodate the
hydroelectric dams. Because of the dams, water levels in Lake Cushman can fluctuate up
to 21 meters (6 feet),with peak levels occurring during summer and minimum levels
during winter. The magnitude of these fluctuations results in periodic inundation of 12
hectares (30 ac es) of land surrounding the inlet to the reservoir, resulting in high water
temperatures ir the shallow waters of the inlet during the summer months (Brenkman
1998). Currently,the reservoir inundates 17.2 kilometers (10.7 miles)of river, including
areas of the on inal Lake Cushman(Brenkman 1998).
5.2 Proposed Project Area
A field investigation was conducted in December of 2017, during which the project area
was surveyed visually on foot. The elevation of the lake's water level was approx. 715
feet,which istwenty-one feet lower than the current ordinary high water mark of 738
feet.
The site suppo s a residential structure located approx. 40 feet vertically and 100 feet
horizontally fr m the shoreline of Lake Cushman. The lot,which slopes steeply to the
shoreline, is heavily vegetated with native species including large trees.
The shoreline as accessed via wooden steps from the residence. Existing over water
structures incl de an older wood ramp, a metal ramp, a pier, and a plastic float. The
lakebed at the site is extremely steep and composed of sand, gravel, cobble and rock. The
shoreline is somewhat protected by jutting shoreline to the south, but is fully exposed to
wave action f om north winds. Runoff from surface flows over the property's steep
slopes also ap ear to be contributing to shoreline erosion. Several large trees have
recently falle onto the shoreline due to bank erosion at the site (Attachment 8).
No fish, invertebrates, or macroalgae were observed in Lake Cushman at the site.
6.0 Effect of the Action
6.1 Direct Effects
Direct effects to the shoreline include: 1)Loss of benthic habitat from the installation of
the bulkhead,pier, and float posts/pipes and the float cradle. 2) Creation of shade from
15
Washington Eliological Evaluation
the replacement pier and existing float. 3)No contamination to Lake Cushman from the
leaching of wood preservatives.
1)As per the engineered design by Steve Morta, approx. nineteen feet(19') of post and
plank wood bulkhead will be installed along the bluff toe at an approx. lakebed elevation
of between 740 and 742 feet. The replacement bulkhead will occupy an elevation that is
landward of the lake's OHWM of 738; therefore, it should not displace any benthic
habitat. The proposed project will also result in the removal of approx. ten small pilings
(with unknown footprints)and the installation of six posts and eight 2"steel pipes. Each
pier post and float cradle pipe with a concrete base will occupy approx. four sf, so the 14
posts/pipes will occupy approx. 56 square feet; however,the area of the posts (approx.
0.5 sf for each post,totaling 4.0 sf and 4 inches for each pipe,totaling .22 sf)will
constitute the only lost surface area, as the concrete bases for each post/pipe will be
covered by the lake's (bottom) substrate. Therefore,the project will occupy a total of less
than one square foot of benthic habitat, which is expected to be mitigated by the removal
of the ten existing pilings.
Additionally, due to the seasonal fluctuations of the lake's water level, it is probable that
benthic species do not thrive in the nearshore areas of the lake that lack permanent water.
No empirical evidence was found to document if both terrestrial and aquatic species
utilize the upper shoreline habitat, or if it has been too altered to support normal
concentrations of either species.
2)Another direct effect is the creation of shade from the replacement pier and the
existing float. The overwater structures at the site produce a reduction in light to the
underlying aquatic environment by creating a light/dark boundary that may give
piscivorous species an advantage over their prey. The use of over-water structures in
western Washington waters by bass, a common, non-native predator of juvenile
salmonids,has been documented by several authors. Largemouth bass in Lake
Washington prefer areas of heavy log and brush cover over other habitat types; however,
they are commonly found under docks in early spring and are thought to be present until
late summer(Stein 1970). Substrate type typically determines the acceptability of an area
for bass spawning, but adjacent cover and structural complexity are also necessary for
protection while the fish are concentrated in shallow water(Stein 1970; Cooper and
Crowder 1979; Helfman 1981 b; Pflug and Pauley 1984). Largemouth bass prefer
moderate to dense vegetation and silt or sand substrate, and nests are constructed at
depths from 0.6 to 1.5 meters, in vegetated areas with soft sediment or gravel substrate on
moderate to steep slopes (Pflug 1981). The substrate type at the proposed project site is
sand, gravel, cobble, and rock, and the lakebed supports no aquatic vegetation, so it is
doubtful that the proposed overwater structure rep lacement/repositioning will increase
the concentration of bass at the site or the occurrence of juvenile salmonid predation by
bass. The project site supports no existing macrophyte vegetation and has no potential to
support macrophyte vegetation, due to the lake's (anthropogenic) seasonal water
fluctuations. In addition, White (1975) determined that phytoplankton primary production
is not significantly reduced by narrow residential piers, due to the presence of more
Washington Biological Evaluation 16
optimal light conditions than found in surface waters, where light intensities are higher
than those in which algae thrive.
Data suggests that other fish species, including salmonids, are also attracted to the shade
produced by over-water structures, so it is possible that adult salmonids could prey on
juveniles at the site. However,researchers have indicated that structural complexity can
moderate predator-prey interactions by providing more refuges for prey species as well as
reducing the foraging efficiency of the predator(Cooper and Crowder 1979). This
moderation ma apply to naturally occurring structural habitat complexity, as well as
habitat complexity due to the presence of docks,piers,boathouses and associated pilings
(WDFW, WD E, WSDOT 2001).
Shade can also ffect migrating salmonids. It is not known whether over-water structures
disrupt the mig ation of salmonids in lakes.Numerous studies suggest that docks,piers,
and floats attract fish, and that the attraction of fish is linked to shade produced by the
object not tacti e stimulus. While the effects of shade on migrating juvenile salmonids in
lakes is unknown, it is also unclear in marine waters, and there is no empirical evidence
of mortality. The significance of predation to migrating populations has never been
empirically assessed (Simenstad et al. 1999).No studies have examined mortality due to
predation much less that mortality is attributable to overwater structures (Nightingale &
Simenstad 200 ).
As previously noted,the proposed project will result in a 140 sf reduction of overwater
structure coverage at the site. Additionally,the replacement pier will be grated to allow
60 percent light passage, as per WDFW's stipulations;the existing pier and float are
presently ungr ted. In conclusion, shade created by the proposed project is expected to
have discountable and insignificant direct effects on ESA listed salmonids that may be in
the action area
3) The leachin of wood preservatives is a common contaminant-related issue with the
construction of shoreline SFR appurtenances. As previously note,no pressure treated
lumber will be used in this project.
Temporary Direct Effects
Temporary direct effects caused by the proposed project include: 1) Turbidity and
sedimentation in Lake Cushman. 2)Noise. 3)Water pollution from incidental release of
fuel, oil, or other contaminants.
1)Disturbed substrate from the removal of existing pilings and in the installation of
new posts/pilings and float crib footings may result in increased turbidity and
sedimentation. As previously discussed, 13MPs will be strictly adhered to during
constraction in order to maintain the present water quality of Lake Cushman and
prevent runoff and pollution. In addition,the proposed project will take place
17
Washington Biological Evaluation
when the water level in the lake is much lower than the OHWM(738'), so it is
probable that rainfall will slowly disperse any disturbed substrate before it comes
into direct contact with the lake's waters. Therefore, it is expected that turbidity
and sedimentation will be minimal.
2) The main source of construction noise will be from the sawing of lumber.Noise
will be intermittent and is expected to be a maximum of 79 dBA at 50 feet.
3)Potential water pollution from accidental release of fuel, oil, or other contaminants
is another possible temporary direct effect. As previously discussed, Spill
Prevention Control measures and BMPs shall be implemented during the
proposed project
6.2 Primary Constituent Elements
PRIMARY CONSTITUENT ELEMENTS
In order to properly analyze the effects on designated critical habitat, a logical framework
must be utilized. In determining what areas constitute critical habitat, agency regulations
require the NMFS to focus on the principal biological or physical constituent elements
that are essential to the conservation of the species. The regulations identify Primary
Constituent elements (PCEs) as including, but not limited to: "roost sites,nesting
grounds, spawning sites, feeding sites, seasonal wetland or dryland,water quality or
quantity, host species or plant pollinator, geological formation, vegetation type,tide, and
specific soil types (69 FR 71888)." In 2003 NMFS biologists developed a list of PCEs
specific to salmon, based on a decision matrix(NMFS, 1996)that describes general
parameters and characteristics of most of the essential features under consideration when
critical habitat is designated. There are six specific types of sites essential to support one
or more life stages of an ESU(sites for spawning, rearing, migration, and foraging). Each
site names physical or biological features (PCEs) essential to the conservation of
salmonids. In 2010, USFWS biologists developed a list of PCEs specific to bull trout,
based on a decision matrix (NMFS, 1996)that describes general parameters and
characteristics of most of the essential features under consideration when critical habitat
is designated. Lakes and reservoirs figure prominently in meeting the life-cycle
requirements of adfluvial bull trout. Lake Cushman is designated critical habitat for the
bull trout and the Chinook salmon; therefore, the direct effects on the designated critical
habitat of bull trout and Chinook salmon have been analyzed using the appropriate PCEs
for the nearshore lacustrine environment.
BULL TROUT PCEs:
Water temperatures that support bull trout use. Bull trout have been documented in
streams with temperatures from 32 to 72 degrees F but are found more frequently in
now
Washington Biological Evaluation 18
temperatures r nging from 36 to 59 degrees F--the project will have no direct effect on
water temperatt res that support bull trout use.
Migratory corridors with minimal physical, biological, or water quality impediments
between spawn ng, rearing, overwintering, and foraging habitats, including
intermittent or seasonal barriers induced by high water temperatures or low flows—
the project's grating of the replacement pier may have a beneficial direct effect on
migratory corridors that support bull trout use. Also,passage will not be altered during
construction as no construction will occur unless the waters of Lake Cushman are low.
An abundant f od base including terrestrial organisms of riparian origin, and aquatic
macroinverteb ates—the project will have no impact.No trees or shrubs will be
removed.
Permanent water of sufficient quantity and quality such that normal reproduction,
growth, andsurvival are not inhibited--the project is expected to have a minimal direct
effect on water quality. Project construction is unlikely to cause temporary turbidity or
sedimentation as work will occur when the lake's waters have been lowered. BMPs are
expected to prevent or moderate potential water pollution during construction. In
addition, no pressure treated lumber will be used.
CHINOOK SALMON PCEs:
Unobstructedpassage—passage will not be altered during construction as no
construction will occur unless the waters of Lake Cushman are low. The project's grating
of the replacement pier may have a beneficial direct effect on Chinook passage along the
shoreline.
Water Quality—project construction is unlikely to cause temporary turbidity or
sedimentation BMPs are expected to prevent or moderate potential water pollution
during construction. In addition, no pressure treated lumber will be used. The use of
yellow cedar(rather than pressure treated lumber) is expected to improve water quality.
Water Quantify—the project will have no effect on water quantity.
Forage--the project will have no impact.No trees or shrubs will be removed.
Natural Cove —the project will not impact existing large woody debris on the lakebed;
however, it is likely that Tacoma Power will eventually remove the wood if it does not
float away.
6.3 Direct Effects to ESA Listed Species
The direct of ct from the proposed project to other ESA listed species that are likely to
be found in the action area have been analyzed as follows
19
Washington Biological Evaluation
NOR THERN SPO TTED OWL
Due to the close proximity of forest land, it is possible that Northern spotted owls may be
found in the action area of the proposed project site. However, with the extensive acreage
of undeveloped forest land nearby, it seems unlikely that Northern spotted owls will be
nesting, roosting, or foraging in close proximity to anthropogenic development.
MARBLED MURRELET
The primary threats to marbled murrelet from anthropogenic activities include loss of
nesting habitat, gill-net fishing operations, oil spills, and marine pollution. Previously
noted BMPs and Spill Prevention Control Measures will be adhered to during project
construction to protect the water quality of Lake Cushman.Noise impacts to any nesting
or foraging murrelets in the action area are expected to be negligible. With the extensive
acreage of undeveloped forest land nearby, it seems unlikely that marbled murrelet will
be nesting, roosting, or foraging in close proximity to anthropogenic development.
6.4 Indirect Effects
Indirect effects are those effects that are caused by or will result from the proposed action
and are later in time, but are still reasonably certain to occur(50 CFR 402.02). Possible
indirect effects from the proposed project include: 1) The loss of shoreline aquatic
vegetation. 2) The replacement pier and repositioned float results in an increased
motorized boat presence at the site.
1) The replacement pier and repositioned float will cause a reduction in light to the
underlying aquatic environment, which can have significant impacts on the health and
productivity of both native and non-native macrophytes and algae. Macrophytes and
algae are the foundation for most freshwater food webs and their presence or absence
affects many higher trophic levels (NMFS 2004). As previously noted,the pier and float
will be grated to allow 60 percent light passage, and the proposed project will result in a
reduction of overwater structure coverage of 140 square feet. However, because the
lakebed beneath both proposed structures lacks water for approx. six to seven months
each year, it is doubtful that it(lakebed) is capable of supporting macrophytic vegetation
that would be benefited by the grating. In conclusion, it is expected that the impact of the
lake's fluctuating water level on littoral productivity will overshadow the impacts of
shading from the pier and float at the site.
2) The pier and float may result in an increased motorized boat presence in the area. Fuel
spills from powerboats can contaminate water quality and potentially affect listed
salmonids directly or indirectly through their prey source (NMFS 2005). Powerboats
also create amplified wave action that can erode the shoreline, and prop scouring can
Washington Biological Evaluation 20
erode benthic habitat, although benthic habitat in the littoral zone is already significantly
marginalized by the Jake's fluctuating water levels. Powerboats also provide some
oxygenation of surface waters, although the extent is probably negligible at best. Overall,
the indirect effects of powerboat usage on Lake Cushman is likely insignificant due to the
lake's large size,the small number of boats that access the remote lake, and the short
boating season(primarily May thru September).
6.5 Primary Constituent Elements
PRIMARY CONSTITUENT ELEMENTS
The indirect e ects on the designated critical habitat of Bull trout and Puget Sound
Chinook have :)een analyzed using the appropriate PCEs for the nearshore lacustrine
environment.
BULL TROUT PCEs:
Water temperatures that support bull trout use. Bull trout have been documented in
streams with temperatures from 32 to 72 degrees F but are found more frequently in
temperatures ranging from 36 to 59 degrees F--the project will have no indirect effect
on water temperatures that support bull trout use.
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—the
project will have no indirect effect on migratory corridors that support bull trout use.
An abundani food base including terrestrial organisms of riparian origin, aquatic
macroinvert brates, and forage fish--the project will have no indirect effect on an
abundant food base for bull trout.
Permanent water of sufficient quantity and quality such that normal reproduction,
growth, and Yurvival are not inhibited—the use of yellow cedar is expected to improve
water quality.
CHINOOK SALMON PCEs:
Unobstructedpassage the project will not have any indirect effect on unobstructed
passage.
Water Quality—the project will benefit water quality(see bull trout).
Water Quantity—the project will not have any indirect effect on water quantity.
21
Washington Biological Evaluation
Forage—the project will not have any indirect effect on foraging opportunities for
Chinook.
Natural Cover—the project will not have any indirect effect on natural cover.
6.6 Indirect Effects to ESA Listed Species
The indirect effects from the proposed project to other ESA listed species that are likely
to be found in the action area have been analyzed as follows:
NORTHERN SPOTTED OWL &MARBLED MURRELET
While it is highly unlikely that either species would nest in trees that are located in a rural
neighborhood, the proposed project may result in increased recreational usage at the site,
which could prompt both species to nest elsewhere.
6.7 Interrelated/interdependent Effects
Interrelated and interdependent effects are described as the effects of the action under
consultation analyzed together with the effects of other activities that are interrelated to,
or interdependent with, that action. An interrelated activity is an activity that is part of the
proposed action and depends on the proposed action for its justification. An
interdependent activity is an activity that has no independent utility apart from the action
under consultation (FWS &NMFS 1998). The project will have no obvious interrelated
or interdependent effects.
6.8 Primary Constituent Elements
BULL TROUT PCEs:
Water temperatures that support bull trout use. Bull trout have been documented in
streams with temperatures from 32 to 72 degrees F but are found more frequently in
temperatures ranging from 36 to 59 degrees F--the project will have no interrelated or
interdependent effects on water temperatures that support bull trout use.
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—the
Washington Biological Evaluation 22
project will have no interrelated or interdependent effects on migratory corridors that
support bull trout use.
An abundant f od base including terrestrial organisms of riparian origin, aquatic
macroinverteb ates, and forage fish--the project will have no interrelated or
interdependent effects on the bull trout's food base.
Permanent wa er of sufficient quantity and quality such that normal reproduction,
growth, and survival are not inhibited--the project will have no interrelated or
interdependent effects on water supply or quality.
CHINOOK SALMON PCEs:
Unobstructed assage the project will have no interrelated or interdependent effects on
unobstructed passage.
Water Quality the project will have no interrelated or interdependent effects on
unobstructed passage.
Water Quanti —the project will have no interrelated or interdependent effects on water
quantity.
Forage the p roject will have no interrelated or interdependent effects on water quantity.
Natural Cover the project will have no interrelated or interdependent effects on natural cover.
6.9 Cumulative Effects
Cumulative effects are defined as "those effects of future state or private activities,not
involving Federal activities,that are reasonably certain to occur within the action area of
the action su Ject to consultation" (50 CFR 402.02). Cumulative impacts are difficult to
access. Cont nued growth and urbanization is likely to detrimentally impact fish and
wildlife reso irces. Global warming could raise the water level of Puget Sound, leaving
many water font properties underwater. Global warming could also result in warmer
water temperatures,to the detriment of species such as bull trout. Additionally, over-
fishing may deplete stocks of salmon, even as restoration of habitat in the watershed
furthers their likelihood of survival.
23
Washington Biological Evaluation
7.0 Conclusion
7.1 Take Analysis
Section 9 of the ESA prohibits take of endangered or threatened species, "take"being
defined in Section 3 as to harass, harm,pursue, hunt, shoot, wound,trap, capture, or
collect listed species, or attempt to engage in any such conduct. "Harm"is further defined
as a significant habitat modification or degradation that actually kills or injures listed
species by"significantly impairing behavioral patterns such as breeding, spawning,
rearing, migrating, feeding, and sheltering" (50 CFR 222.102). "Harass" is further
defined as an intentional or negligent act which creates the likelihood of injury to wildlife
by annoying it to such an extent as to significantly disrupt normal behavior patterns
which include, but are not limited to, breeding, feeding, or sheltering(50 CFR 17.3). In
regards to the proposed project and the existing development activities, it is extremely
unlikely that any "take"will occur. Previously listed conservation measures will her
insure the likelihood that no "take"will occur
7.2 Determination of Effect
A determination of May affect, not likely to adversely affect is the appropriate conclusion
when effects on the species or their critical habitat are expected to be beneficial,
discountable, or insignificant. After reviewing the appropriate data and survey
information, I have concluded that the proposed project will have an insignificant impact
on the previously discussed Endangered or Threatened species if the previously discussed
conservation measures are implemented. In my most honest and professional opinion,
while the proposed project may impact individual Endangered or Threatened species in
the project area, it is not likely to adversely affect or jeopardize the continued existence
of those species or their designated Critical Habitat. The determination of effect for each
of the listed species is:
1. Bull trout and their designated Critical Habitat—May affect, not likely to
adversely affect.
2. Chinook salmon--May affect, not likely to adversely affect.
3. Marbled murrelet May affect, not likely to adversely affect.
4. Northern spotted owl No effect.
5. Streaked horned lark---No effect.
6. Yellow-billed cuckoo No effect.

Essential Fish Habit Assessment
Essential Fish Habitat Assessment
A. Background
The Magnuson Fishery Conservation and Management Act was signed into law on April 13,
1976. Under pro 'isions of the Act, eight Regional Fishery Management Councils were
established to prepare FMP's in conformance with national standards published in 50 CFR Part
600.305-340. The Magnuson Act was renamed the Magnuson-Stevens Act in a 1996
appropriations bill. On October 11, 1996,the Sustainable Fisheries Act,which amended the
Magnuson-Steve s Act, was signed into law. Provisions included a mandate that the Councils
amend each FMP to include a description of Essential Fish Habitat, including adverse impacts on
EFH and conservation measures to protect EFH. Essential Fish Habitat is defined as those waters
and substrate nec ssary to fish for spawning,breeding, feeding, or growth to maturity.
The Pacific Fisheries Management Council has designated EFH for federally-managed species
on the Pacific West Coast, including 82 species of groundfish, 5 coastal pelagic species, and 3
species of salmon. The following species may occur in Lake Cushman during some period of
their life history: Chinook salmon(Oncorhynchus tshawytscha) and Coho salmon
(Oncorhynchus A isutch).
B. Essential ish Habitat
The designated EIFH for Pacific salmon species is identified using U.S. Geological Survey
(USGS)hydrologic units as well as habitat association tables and life history descriptions of each
life stage (PFM 1999). The EFH for the Pacific coast salmon fishery is defined as those waters
and substrate necessary for salmon production needed to support a long-term sustainable salmon
fishery and salrin on contributions to a healthy ecosystem (WSDOT 2014). To achieve that level
of production,EFH must include all those streams, lakes,ponds,wetlands, and other currently
viable water bodies and most of the habitat historically accessible to salmon in Washington,
Oregon, Idaho, i trid California(WSDOT 2014). This does not include habitats above the
impassible barriers identified by the Pacific Fishery Management Council Fishery Management
Plan(PFMC 1999).
C. Proposed Action
The proposed project is the installation of a new 19-foot wood bulkhead and float cradle, and a
replacement pier and ladder. An existing float will remain but be relocated.
Page 37
Washington Bic logical Evaluation
D. Effects of the Proposed Action
The effects of the proposed project on designated EFH are expected to be comparable to the
effects described in the attached BE.
E. Conservation Measures
The conservation measures and BMPs discussed in the attached BE will be implemented to
minimize any adverse effects to Essential Fish Habitat.
F. Conclusion
The proposed project is likely to have no significant impact on designated EFH for Pacific
salmon.

Part 6—Project Description
;i
The proposed action on t eir Lake Cushman property is the installation of an approx. 19-foot wood
bulkhead with inset shoreline access steps and the replacement of an existing pier, ramp, and float with
a new pier and ladder. An existing EZ-Dock float(made of polyethylene plastic)will be re-used and fitted
with a float landing cradle.
The bluff toe at the site exhibits erosion damage that is common to the Lake Cushman shoreline. There
are three primary causes of this erosion and concomitant shoreline instability:
• The seasonal raisi ig and lowering of Lake Cushman, a reservoir with two functioning dams.
• The lake's unique andscape features, including a steep, unnatural lakebed topography that lacks
a shallow foresho a to diminish wave energy generated by strong prevailing winds and approx.
eight miles of fetch.
• A steep terrestrial shoreline that receives an average of approx. 100 inches of rainfall per year.
The west side of Lake Cushman is also subjected to damaging surface flows due to clear cut logging on
the steep slopes above the shoreline. The applicant's property features heavily vegetated steep slopes
and an extremely steep 1 kebed adjacent to the shoreline. Bluff toe erosion has caused several large
trees to fall onto the shoreline at the site. Due to the existing bluff toe erosion and the potential for
further slope instability in the vicinity of shoreline access at the site, shoreline protection in the form of
a wood bulkhead is proposed. The bulkhead will be the minimal length necessary to protect shoreline
access to existing and proposed overwater structures.
Additionally, the applicants' existing pier and access ramp is old and in need of repair and replacement.
The applicants wish toe tend the life of the existing overwater structures,while at the same time
making them safer for bc th humans and the environment. Therefore, the project objective is to install a
new bulkhead of minima size that is long enough to protect shoreline access and renovate an existing
overwater structure, all-tie-while avoiding or minimizing impacts to ESA-listed species and improving
shoreline habitat at the site.

As per the engineered design by Steve Morta, approx. nineteen feet(19') of post and plank wood
bulkhead will be installed along the bluff toe at an approx. lakebed elevation of between 740 and 742
feet. The proposed bulkhead will be an average above grade height of four(4)feet. The bulkhead will be
constructed of six by six inch (6"x 6") Alaska yellow cedar posts, two by twelve-foot(2' x 12')yellow
cedar planks, and galvanized hardware. Shoreline access steps constructed of Alaska yellow cedar will
be inset into the bulkhead near the center.
The existing overwater structure will be removed, with the exception of the existing five by approx.
nineteen-foot(5' x 19.5') EZ Dock float, and replaced with a six by thirty-three-foot(6' x 33') pier and a
manufactured vertical ladder. The pier will be attached to the bulkhead with metal hardware and
supported by six (6)six by six inch (6"x 6") Alaska yellow cedar posts. The existing float will be
repositioned. Two(2)steel I-beams will be field welded to eight(8), two-inch (2")steel pipes set in
concrete footings to create a float crib that will give the float a minimum of 18 inches of lakebed
clearance during the low water season. The vertical ladder will provide access between the pier and
float. All concrete for the bulkhead, pier, and float will be hand-mixed per engineered drawings and
poured in place.
The pier and float will be constructed of galvanized steel or aluminum hardware, and Alaska yellow
cedar posts,joists, decking, and trim, or composite decking and trim. The decking of the pier and float
will have grating installed (greater than fifty percent total with 60 percent light passage, as required by
the WDFW). The total overwater coverage at the site will be 296.5 square feet, a reduction of 140 sf from
the existing 436.5 square feet.
All piling holes will be three feet(3') deep and approx. eighteen inches (18')wide, and filled with
concrete. No pressure treated lumber will be used in this project. All overwater structures will be grated
with ThruFlow decking panels, which are made of reinforced polypropylene, contain no toxic
preservatives, and are recyclable.
JARPA Revision 2012.1 Page 6 of 15
A circular saw and variou hand tools will be used throughout the proposed project.Workers,
equipment, debris, and m terials will be transported to the site either by boat or by cars or trucks. Geo-
textile fabric will be sprea over the dry lakebed before commencement of project construction in order
to contain any manmade onstruction debris. At the completion of construction, the geo-textile fabric
will be removed from the horeline at the site, along with all construction debris and other existing
manmade debris. All deb is will be disposed of at a licensed landfill or other licensed disposal site.
All activities are within the 100-year flood plain. The nearest waterbody is Lake Cushman.

agencies may modify this form to include additional specific information on
project description).
As per the engineered design by Steve Morta, approx. nineteen feet(191) of post
and plank wood bulkhead will be installed along the bluff toe at an approx.
lakebed elevation of between 740 and 742 feet. The proposed bulkhead will be an
average above grade height of four(4) feet. The bulkhead will be constructed of
six by six inch (6"x 6") Alaska yellow cedar posts, two by twelve-foot(2' x 12')
yellow cedar planks, and galvanized hardware. Shoreline access steps
constructed of Alaska yellow cedar will be inset into the bulkhead near the center.
The existing overwater structure will be removed, with the exception of the
existing five by approx. nineteen-foot(5' x 19.5') EZ Dock float, and replaced with
a six by thirty-three-foot (6' x 33') pier and a manufactured vertical ladder. The pier
will be attached to the bulkhead with metal hardware and supported by six (6) six
by six inch (6"x 6") Alaska yellow cedar posts. The existing float will be
repositioned. Two (2) steel 1-beams will be field welded to eight(8), two-inch (2")
steel pipes set in concrete footings to create a float crib that will give the float a
minimum of 18 inches of lakebed clearance during the low water season. The
vertical ladder will provide access between the pier and float. All concrete for the
bulkhead, pier, and float will be hand-mixed per engineered drawings and poured
in place.
The pier and float will be constructed of galvanized steel or aluminum hardware,
and Alaska yellow cedar posts,joists, decking, and trim, or composite decking
and trim. The decking of the pier and float will have grating installed (greater than
fifty percent total with 60 percent light passage, as required by the WDFW). The
total overwater coverage at the site will be 295.6 square feet, a reduction of 140 sf
from the existing 436.6 square feet.
All piling holes will be three feet(3') deep and approx. eighteen inches (18')wide,
and filled with concrete. No pressure treated lumber will be used in this project.
All overwater structures will be grated with ThruFlow decking panels, which are
made of reinforced polypropylene, contain no toxic preservatives, and are
recyclable.
A circular saw and various hand tools will be used throughout the proposed
project. Workers, equipment, debris, and materials will be transported to the site
either by boat or by cars or trucks. Geo-textile fabric will be spread over the dry
lakebed before commencement of project construction in order to contain any
manmade construction debris. At the completion of construction, the geo-textile
fabric will be removed from the shoreline at the site, along with all construction
debris and other existing manmade debris. All debris will be disposed of at a
licensed landfill or other licensed disposal site.
All activities are within the 100-year flood plain. The nearest waterbody is Lake
Cushman.

Dear Ms. Watson:
Thank you for the opportunity to comment on the determination of nonsignificance for the
Washington Bulkl ead,Pier, Ladder, &Float Project(SEP2018-00052, SHX2018-00038, and
GE02018-00032) located at 2190 West Cushman Ridge Road in Shelton as proposed by Caralyn
Valdeman of Integrated NW Construction, LLC for Suzanne Washington. The Department of
Ecology(Ecology)reviewed the environmental checklist and has the following comment(s):
SOLID WASTE MANAGEMENT: Derek Rockett(360) 407-6287
All removed debris and dredged material resulting from this project must be disposed of at an
approved site. Contact the local jurisdictional health department for proper management of
these materials.
WATER QU LITY: Chris Montague-Breakwell (360)407-6364
Erosion control measures must be in place prior to any clearing, grading, or construction.
These control measures must be effective to prevent stormwater runoff from carrying soil
and other poll tants into surface water or stormdrains that lead to waters of the state. Sand,
silt, clay particles, and soil will damage aquatic habitat and are considered to be pollutants.
Any discharge of sediment-laden runoff or other pollutants to waters of the state is in
violation of Chapter 90.48 RCW, Water Pollution Control, and WAC 173-201A, Water
Quality Standards for Surface Waters of the State of Washington, and is subject to
enforcement action.
The following construction activities require coverage under the Construction Stormwater
General Permit:
1. Clearing, grading and/or excavation that results in the disturbance of one or more
acres and discharges stormwater to surface waters of the State; and

2. Clearing, grading and/or excavation on sites smaller than one acre that are part of a
larger common plan of development or sale, if the common plan of development or
sale will ultimately disturb one acre or more and discharge stormwater to surface
waters of the State.
a) This includes forest practices (including, but not limited to, class IV conversions)
that are part of a construction activity that will result in the disturbance of one or
more acres, and discharge to surface waters of the State; and
3. Any size construction activity discharging stormwater to waters of the State that
Ecology:
a) Determines to be a significant contributor of pollutants to waters of the State of
Washington.
b) Reasonably expects to cause a violation of any water quality standard.
If there are known soil/ground water contaminants present on-site, additional information
(including, but not limited to:temporary erosion and sediment control plans; stormwater
pollution prevention plan; list of known contaminants with concentrations and depths found;
a site map depicting the sample location(s); and additional studies/reports regarding
contaminant(s))will be required to be submitted.
You may apply online or obtain an application from Ecology's website at:
http://www.ecy.wa.jzov/programs/wq/stormwater/construction/-Application. Construction
site operators must apply for a permit at least 60 days prior to discharging stormwater from
construction activities and must submit it on or before the date of the first public notice.
Ecology's comments are based upon information provided by the lead agency. As such, they
may not constitute an exhaustive list of the various authorizations that must be obtained or legal
requirements that must be fulfilled in order to carry out the proposed action.
If you have any questions or would like to respond to these comments, please contact the
appropriate reviewing staff listed above.
