Project Name:Deleo&Latham Bulkhead Project
Description of Proposal: Construction of approximately 280 lineal feet of I-beam pile
and wood bulkhead on two neighboring lots on Lake Cushman.
Location: Lots.60&61 N.Gull Place,Lake Cuslunan,Hoodsport, WA.
Proponent: Therese DeLeo &Steve&Amy Latham
Dear Ms Wright,
It has been determined that the above project will have multiple negative
environmental impacts to the Skokomish Tribe and/or their resources, including multiple
Federal and State listed species. These impacts are listed in detail below and should be
thoroughly considered before any permits are issued by the permitting agencies and/or
construction begins.
• Bulkheads may disrupt the migratory and rearing behavior of juvenile salmonids
• Bulkheads prevent the recruitment of native sediment to the lake,resulting in a
loss of heterogenous substrate,and resulting in shoreline erosion at the toe or
along the shore downwind of the bulkhead. This could affect the availability of -
spawning and rearing habitat, and the forage base for a variety of fish species. :E
• Bulkheads eliminate shallow-water habitat,which is critical as refuge and foraging
habitat for juvenile salmonids and other small fish.
• Bulkheads reflect wave energy at the shoreline,resulting in the scour of sdiment
oat the bulkhead toe, and creating an inhospitable high-energy environment for
juvenile fish.
• The removal of vegetation during bulkhead construction could eliminate a
potential source of cover and food for juvenile salmonids, forage fish and native
char. Vegetation removed is typically not replaced with native woody species
that could provide a future source of woody debris to the lake thereby reducing
the availability of complex refuge habitat for small fish,and attachment surfaces
for periphyton.
• The temporary turbidity associated with bulkhead construction may reduce water
quality to the detriment of juvenile fish species.

Reply to the Skokomish Tribe's "issues" with the Deleo and Latham
bulkhead project.
Bulkheads may disrupt the migratory and rearing behavior of juvenile salmonids.
• The footprint of the bulkhead's piles will be located just waterward of the lake's high
water mark of 738 feet, so the piles and the face of the bulkhead are only expected to be
exposed to water during 4 months(June thru September), and then only just barely,with
the exception of waves generated by boat wake and the wind. It should be noted that the
.lake is not always raised to its highest level each year. In addition,the bulkhead will not
displace any shoreline emergent vegetation that would provide habitat for juvenile
salmonids. The bluff at the site is steep and scarcely vegetated, with little overhanging
upland vegetation to provide shade or insects for salmonids and no emergent vegetation
for shelter. Therefore,the bulkhead is expected to have an insignificant impact on
migratory and rearing behavior of juvenile salmonids in the lake.
Bulkheads prevent the recruitment of native sediment to the lake,resulting in a loss of
heterogeneous substrate,and resulting in shoreline erosion at the toe or along the shore
downwind of the bulkhead. This could affect the availability of spawning and rearing
habitat, and the forage base for a variety of fish species.
• The majority of adfluvial salmonids spawn in rivers or streams that discharge into lakes.
Lake trout spawn in lakes,but the eggs drift freely with the current until coming to rest
on the bottom and are not covered with gravel by the female.
• The steep,slope of the shoreline at the site presents an inhospitable high-energy
environment with or without the presence of a bulkhead, due to the lack of shallow water
to dissipate wave energy. The foreshore from the OHWM, waterward,is composed
primarily of cobble as finer materials have been previously eroded and transported from
the site by wave action. The bulkhead will impound sediments. However,presently,
heterogeneous sediments from the bluff at the site are being transported to deeper water
where they(sediments)are not available to the nearshore for spawning or rearing habitat
(due to the steep nearshore slopes in the area). Therefore,the addition of a bulkhead is
unlikely to impact the nearly homogeneous armored surface layer of cobble at the site.
Bulkheads eliminate shallow-water habitat,which is critical as refuge and foraging habitat
for juvenile salmonids and other small fish.
• The shoreline at the site is unnaturally steep,due to the unnatural nature of Lake
Cushman. It is therefore impossible for the proposed bulkhead to eliminate shallow-
water habitat that does not presently exist.
Bulkheads reflect wave energy at the shoreline,resulting in the scour of sediment at the
bulkhead toe, and creating an inhospitable high-energy environment for juvenile fish.
• The footprint of the piles will be located just waterward of the lake's high water mark of
738 feet,so the piles and the face of the bulkhead are only expected to be exposed to
water during 4 months(June thru September),and then only just barely,with the
exception of waves generated by boat wake and the wind. Once again,this is contingent
upon the lake being raised to its highest level,which is not always the case. Presently,
the steep slope of the nearshore area at the site presents an inhospitable high-energy
environment,due to the lack of shallow water to dissipate wave energy. The foreshore
from the OHWM,waterward, is composed primarily of cobble as finer materials have
been previously eroded and transported from the site by wave action. The addition of a
bulkhead is unlikely to make this area any more(or less)inhospitable to juvenile fish or
other aquatic species.
The removal of vegetation during bulkhead construction could eliminate a potential source
of cover and food for juvenile salmonids,forage fish and native char. Vegetation removed
is typically not replaced with native woody species that could provide a future source of
woody debris to the lake thereby reducing the availability of complex refuge habitat for
small fish, and attachment surfaces for periphyton:
• Minimal vegetation shall be removed as a result of this project. As per the Deleo/Latham
bulkhead HMP: Native vegetation shall be planted along the top of the bulkhead. At
least 80 shrubs or ferns(five-feet on-center)`shall be installed: Vegetation may be
harvested on site and transplanted,or, if purchased from a nursery or the Mason County
Conservation District sale,be in one or two gallon-pots or bare root. Plants shall include
the-following and/or other suitable native species: vine-inaple(Acer circinatum),Pacific
dogwood(Cornus nuttallii),Western yew(Taxus brevifolia)`evergreen huckleberry
(Yaccinium ovatum),red huckleberry(Vaccihium parvifolium),Rhododendron
(Rhododendron macrophyllum), Indian plum(Oemleria cerasiformis),oceanspray
(Holodiscus discolor); snowbru8h(Ceanothus velutinus var. hookeri),salal(Gaultheria
shallon),Oregon-grape(Berberis aquifolium),Thimbleberry(Rubus parviflorus var.
parviflorus),and sword fern(Polystichurit'munitunt).
• Thektemporary turbidity associated with bulkhead construction;may reduce water quality-
to-the-detriment of juvenile fish species.
As per the Deleo/Latham HMP:- Disturbed substrate from the:installation of the bulkhead
may result in increased turbidity and sedimentation and/or siltation, which might effect'
- -the migration of juvenile salmonids along the shoreline by creating a temporary barrier in
-the littoral zone. Juvenile salmonids are mobile, so it is possible that they will avoid the
area of disturbance and not be impacted. Salmonids have been observed to move
laterally and downstream to avoid turbidity plumes(Sigler et al. 1984,Lloyd 1987,
Scannell 1988). Gregory and Northcote(1993)suggested that turbidity could be used as
a protective cover by juvenile salmon. As previously discussed,BMP's will be strictly
adhered to during construction in order to maintain the present water quality of Lake
Cushman and prevent runoff and pollution. In addition,the proposed project will take
place 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 water. Therefore,it is expected that turbidity, sedimentation
and/or siltation will be minimal
Pile driving even using non-mechanized machinery may disrupt the distribution and
behavior of,or injure juvenile fish species.
• As per the Deleo/Latham HMP: Holes for the posts will be augered by hand(with hand
tools). No construction to take place when the water level of Lake Cushman is elevated
(approximately May 26'h to October 1 S).
• While salmonid eggs are potentially vulnerable to detrimental impacts from noise,work
shall be completed when the water level is low,so it is doubtful that the use of non-
mechanized tools(i.e. shovels)on the dry shoreline will impact salmonids or other fish
and aquatic species.
Best Management Practices instituted by the Western Wood Preservers Institute(WWPI)
should be employed for the use of ACZA treated wood when used in the aquatic
environment.
• Yes, ACZA treated wood used in the project shall undergo on or more of the following
BMP'sto minimize leaching of contaminants` 1)Aqua-Ammonia Steaming Cycle
(AASC). 2)Post Treatment Kiln Drying. 3)Minimum Plant Holding Time ("MPHT").
In addition to recommendations for the ACZA BMPS-Amendment#1 for "MPHT"
treatment,all ACZA treated wood shall be held under cover a minimum of 3 weeks at a
constant temperature thatrneets or exceeds 60 degrees F. If the ambient temperature is
less than60 degrees F then ACZA treated wood must undergo the Post Treatment Kiln
Drying,noted above. 4)In-Retort Ammonia Removal Plus Plan Holding Time(MPHT),
as conditioned in previous section(3), but held under cover for minimum of 1-week,at
a constant temperature that meets or exceeds"60 degrees F: 4)ACZA wood treatment
methods shall be verified by'providing'a signed and dated certificatiori:from a third party.
A key to the treating process:for ACZA treated wood is the presence of ammonia,which
facilitates carrying the active ingredients into the cell structure of-the wood during
treatment. Evaporation and removal of the ammonia following treatment is critical for the
`'f6rnaiht ingredients to become-,stabilized there-byn ittiniizing the opportunity for
leaching from the product in its end use.
See above.. -
It is recommended that several key pieces of large woody debris(LWD) depicted in the
enclosed Habitat Management Plan ' " , be anchored'a ro riatel along the shoreline
g fop)` PP p � Y g .
to further deflect wave energy away from the proposed structure.
• Existing woody debris shall be anchored along the toe of the bulkhead to lessen toe
erosion, after construction is completed.
In addition it is recommended that the concrete for the proposed piles have an aquatic
friendly sealant applied to them during low tides.
• If a sealant is applied to concrete used in the project,it(sealant)will be aquatic friendly.
The west slope of the proposed properties is the most stable according to the enclosed geo-
report. This slope should be preserved as a Best Management Practice(BMP)for this site's
stormwater runoff. Dispersing stormwwater into vegetated areas of the yard should be
employed as the primary stormwater BMP for this site and location.
