Hello Donna –
Attached please find updated versions of the documents submitted in connection with the above
matter. The versions of the documents have all been updated with filenames that correspond to earlier
submissions, but with the addition of “R10-20 to indicate that they are the most recent versions of these
documents from October 2020. The .pdf versions of these documents total less than 13 MB, so it should
be possible to transmit them all with this email. Please confirm to me that they have been successfully
received (BDN001- BDN016). We are happy to provide hard copies if desired – just let me know.
The documents have been revised, as needed, to remove all references to the use of mesh tubes or area
netting, since only PVC tubes will be used on the project, and no area netting, rebar or other anchors
will be used. Some of the documents did not require any revision, but in order to be sure that we are all
looking at the same, and latest, versions of the application package, I have assigned the same”R10-20”
suffix to each one. Unless I have missed something, we should not have to be looking at any earlier
versions or other documents that do not have the “R10-20” designation. This should avoid any
confusion or inconsistencies.
Hopefully , we are now at a point to move this matter along in a timely fashion. Please let me know if
you require anything further from us.

SEPA Environmental checklist (WAC 197-11-960) Responses Revised May 26, 2020 Page 1 of 22
SEPA ENVIRONMENTAL CHECKLIST
Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your
proposal are significant. This information is also helpful to determine if available avoidance, minimization
or compensatory mitigation measures will address the probable significant impacts or if an environmental
impact statement will be prepared to further analyze the proposal.
Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please
answer each question accurately and carefully, to the best of your knowledge. You may need to consult
with an agency specialist or private consultant for some questions. You may use “not applicable” or
"does not apply" only when you can explain why it does not apply and not when the answer is unknown.
You may also attach or incorporate by reference additional studies reports. Complete and accurate
answers to these questions often avoid delays with the SEPA process as well as later in the decision-
making process.
The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of
time or on different parcels of land. Attach any additional information that will help describe your proposal
or its environmental effects. The agency to which you submit this checklist may ask you to explain your
answers or provide additional information reasonably related to determining if there may be significant
adverse impact.
Instructions for Lead Agencies:
Please adjust the format of this template as needed. Additional information may be necessary to
evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse
impacts. The checklist is considered the first but not necessarily the only source of information needed to
make an adequate threshold determination. Once a threshold determination is made, the lead agency is
responsible for the completeness and accuracy of the checklist and other supporting documents.
Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable
parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please
completely answer all questions that apply and note that the words "project," "applicant," and "property or
site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead
agency may exclude (for non-projects) questions in Part B - Environmental Elements –that do not
contribute meaningfully to the analysis of the proposal.

BDN proposes to cultivate Pacific geoduck (Panopea generosa). The planting area will consist
of approximately 5.15 acres, generally between approximately +2 ft. MLLW and a 5-meter
(16.4 ft.) buffer of the native eelgrass (Zostera marina) bed edge, located between
approximately -1MLLW and -2 MLLW.
To protect geoduck seed from predators, PVC tubes 4” in diameter by 10" long will be manually
placed in the substrate at low tide, while the tidelands are exposed, before any geoduck seed
is planted. The tubes are inserted into the substrate such that at least half of the tube is below
the substrate and the remainder is above it. A low pressure water hose may be used to loosen
the substrate sufficiently to properly insert the tubes. Tubes will be spaced at approximately
one tube per square foot in the planting area. Only 3”-5" of the tubes will be exposed above the
substrate. Tubes will be labeled with contact information for BDN. 12-25 workers will work to
insert these PVC tubes during each approximately 5-hour shift. This will allow for
approximately 6,000-10,000 tubes to be placed per day.
Geoduck seed will then be obtained from a certified hatchery and typically planted in the
installed PVC tubes when 4-5 mm in size. The juvenile geoducks will be placed in the installed
tubes by divers during times when the tubes are submerged. No water jets will be used during
placement of the seed in the PVC tubes. The PVC tubes will be covered with a mesh cap and
secured with UV-resistant rubber bands after the seed has been planted. Planting will begin in
spring and continue through fall. Planting activities will occur once per year, typically in June or
July, over a period of 20-25 days.
No netting will be installed over the tubes, and no rebar or other materials will be used in
connection with the planting maintenance or harvest activities. The installed PVC tubes are
very resistant to dislocation during severe weather, or from geoduck movement and activity, so
no securing nets are necessary. Any dislodged tubes do not float, and thus tend to remain on
or near the tract even if dislodged, where they can be retrived by regular beach inspections.
No fill materials or other nursery/grow-out structures will be installed on the site. The project
may result in the removal of non-native Japanese dwarf eelgrass (Z. japonica) located in the
proposed planted area.
Site inspections will be made weekly, or more frequently if needed due to adverse weather or
citizen complaints, to ensure that PVC tubes have not become dislodged. BDN has
implemented an aquaculture gear maintenance plan, appended as Attachment I-2, to address
potential gear escapement and to facilitate quick recovery of any gear displaced by storm
activity. Site inspections will be generally conducted by 2-4 BDN employees walking the
Log Item 36
Page 12 of 218
SEPA Environmental checklist (WAC 197-11-960) Responses Revised May 26, 2020 Page 5 of 22
tidelands and surrounding areas at low tide. Site maintenance will also include monitoring and
relocation of built-up drift microalgae (e.g. Ulva). If low tide periods occur at night, these
workers may use individual LED headlamps for such inspection and maintenance work. If any
maintenance work is required, this will be performed by as many as four people, but should
typically require no more than 1 hour for each such maintenance event. No vessel operations
will take place at night.
Two years after planting, when the geoducks have reached a depth sufficient to avoid
predators, beach workers will remove the tubes by hand at low tide. Consistent with Corps
requirements, if any herring spawn is found on the PVC tubes, they will not be removed until
the eggs have hatched. The tubes will be placed in large bags and removed for reuse or proper
upland disposal.
Usually, harvesting will begin between five and six years after planting; the exact timing of
harvesting will depend on a variety of environmental and economic factors. The total harvest
window is expected to be 1-2 years. The majority of harvesting will be conducted at high tides
by divers using surface-supplied air. A small amount of beach harvesting will be conducted
during the "cleanup" harvest phase at the end of the harvesting period when there are fewer
geoducks remaining on the beach. Both dive harvests and beach harvests use the same
extraction equipment. A diesel or gasoline engine located on the work skiff is used to power a
water jet nozzle that loosens the substrate around each geoduck. The engine will have a
muffler to minimize noise impacts. The water intake hose will include a 2.36 mm wire mesh
screen covering the intake to prevent fish entrainment in the low-pressure pump. The water jet
nozzle is at the end of an approximately 150' long, 1.5" delivery hose. The nozzle is
approximately 27" long and may supply up to 20-30 gallons of water per minute at 40 psi
After geoducks are removed from the substrate as described above, they will be stored in
crates located on the work skiff prior to transport off-site. During both dive and beach
harvesting, the work skiff will not be anchored in any native eelgrass beds. Dive harvests will
be conducted during daylight hours. Divers work within a 150' radius of the work skiff at depths
of 5' to 20' using surface supplied air. The vessel engine will be turned off while divers are
working for diver safety. When beach harvesting, the skiff is regularly moved so that it always
remains near the water's edge. Water hoses are then run from the skiff to the beach. Dive
harvests will employ 1 diver and 2 support workers in the skiff. Dive harvesting will usually last
for 3-to 6 hours each harvest day. Beach harvests will employ 2 workers on the beach and 2
support workers on the skiff.
Harvesting activities at this location will occur only during daylight hours, over a period of about
5 hours per day, averaging 3-4 harvest days per week during the one to two year harvest
period. BDN will comply with Corps' conditions associated with herring, surf smelt, and sand
lance spawning.

B. Environmental Elements [HELP]
1. Earth [help] a. General description of the site:
(circle one): Flat, rolling, hilly, steep slopes, mountainous, other:
Gently Sloping Tidelands
(Note: See Addendum M-1 through M-6 for description of related upland parcels) b. What is the steepest slope on the site (approximate percent slope)?
Approximately 1% slope. The site slopes about 4 feet over its approximately 400 foot
width, from +3 MLLW to -2 MLLW.
c. What general types of soils are found on the site (for example, clay, sand, gravel, peat,
muck)? If you know the classification of agricultural soils, specify them and note any agricultural
land of long-term commercial significance and whether the proposal results in removing any of
these soils.
Substrate at the Smersh site consists mainly of well‐sorted, clean, sand with an adjacent
sandy, gravelly beach.
d. Are there surface indications or history of unstable soils in the immediate vicinity? If so,
describe.
No.
e. Describe the purpose, type, total area, and approximate quantities and total affected area of any
filling, excavation, and grading proposed. Indicate source of fill.
There is no proposed filling, excavation or grading.
f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe.
No.
g. About what percent of the site will be covered with impervious surfaces after project
construction (for example, asphalt or buildings)?
Log Item 36
Page 14 of 218
SEPA Environmental checklist (WAC 197-11-960) Responses Revised May 26, 2020 Page 7 of 22
No impervious surface will be created as part of this project.
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any:
No erosion is anticipated so no erosion control measures will be implemented.
2. Air [help] a. What types of emissions to the air would result from the proposal during construction, operation,
and maintenance when the project is completed? If any, generally describe and give
approximate quantities if known.
The only anticipated emissions will be from engines and pumps on one small harvest
vessel (under 40’) or from skiff mounted engine-driven pumps when dive or beach
harvesting is occurring on the project. Usually, harvesting will begin between four and
seven years after planting, but the total harvest window is expected to be 1 year.
Dive harvests will be conducted only during daylight hours. Vessel engines will be turned
off while divers are working for diver safety. When beach harvesting, a skiff with a gasoline
powered pump will be used to provide water for extraction. Dive harvesting will usually last
up to 5 hours each day, and beach harvesting will be done only in a low tide window of 3
hours or less. Thus, the emissions from the use of no more than two small gasoline or
diesel engines associated with harvesting should not have a significant impact on air quality
in the vicinity of the project.
b. Are there any off-site sources of emissions or odor that may affect your proposal? If so,
generally describe.
None that are known to applicant
c. Proposed measures to reduce or control emissions or other impacts to air, if any:
Not applicable.
3. Water [help] a. Surface Water: [help] 1) Is there any surface water body on or in the immediate vicinity of the site (including
year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type
and provide names. If appropriate, state what stream or river it flows into.
The Project area consists of Squamish Harbor saltwater tidelands that are exposed
and covered on a daily basis. Shine Creek, a freshwater creek, is approximately 1.5
miles to the west. A small un-named stream enters Squamish Harbor near the
project site.
2) Will the project require any work over, in, or adjacent to (within 200 feet) the described
waters? If yes, please describe and attach available plans.
Yes. See A. 11. above, which describes the nature and extent of all work to be
performed at the site, all of which would be within 200 feet of all described waters except
for Shine Creek. Log Item 36

3) Estimate the amount of fill and dredge material that would be placed in or removed
from surface water or wetlands and indicate the area of the site that would be affected.
Indicate the source of fill material.
There is no proposed filling, excavation or grading.
4) Will the proposal require surface water withdrawals or diversions? Give general
description, purpose, and approximate quantities if known.
No.
5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan.
Yes, being tidelands, the site lies withing the 100 year flood plain.
6) Does the proposal involve any discharges of waste materials to surface waters? If so,
describe the type of waste and anticipated volume of discharge.
No.
b. Ground Water: [help] 1) Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a
general description of the well, proposed uses and approximate quantities withdrawn from
the well. Will water be discharged to groundwater? Give general description, purpose, and
approximate quantities if known.
No.
2) Describe waste material that will be discharged into the ground from septic tanks or
other sources, if any (for example: Domestic sewage; industrial, containing the
following chemicals. . . ; agricultural; etc.). Describe the general size of the system, the
number of such systems, the number of houses to be served (if applicable), or the number
of animals or humans the system(s) are expected to serve.
None.
c. Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection
and disposal, if any (include quantities, if known). Where will this water flow?
Will this water flow into other waters? If so, describe.
No runoff (including storm water) will result from Project operations.
2) Could waste materials enter ground or surface waters? If so, generally describe.
No. Log Item 36

3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so,
describe.
No.
d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern
impacts, if any:
There should be none needed.
4. Plants [help] a. Check the types of vegetation found on the site:
_ X_ deciduous tree: alder, maple, aspen, other
____ evergreen tree: fir, cedar, pine, other
_ X_ shrubs
__X_ grass
____ pasture
____ crop or grain
____ Orchards, vineyards or other permanent crops.
____ wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other
_X__ water plants: eelgrass
____ other types of vegetation
b. What kind and amount of vegetation will be removed or altered?
There will be no removal of native materials during site preparation. Excessive amounts of
macroalgae (e.g. Ulva) may be hand-raked away from the planting area, but left on the site.
Successive tides will redistribute algae across the site. The project may result in the
removal of non-native dwarf Japanese eelgrass (Zostera japonica) located in the proposed
planted area.
Macroalgae beds are not found in or near the project area. Green algae (Ulva) were present
at a very low density, attached to a small number of hard objects such as derelict clam shells.
Macroalgae density is anticipated to increase in the project area due to geoduck farming as
the PVC tubes provide solid substrate required by macroalgae for attachment and growth.
Because the project will be located outside of a 16‐foot protective buffer from native eelgrass,
no negative effects are anticipated to occur to eelgrass due to the proposed project and there
may be an ecological lift from the potential increase in other macroalgal species on the PVC
tubes.
c. List threatened and endangered species known to be on or near the site.
No threatened or endangered plant species are found on the site.

d. Proposed landscaping, use of native plants, or other measures to preserve or enhance
vegetation on the site, if any:
All project activity will occur at least 16 feet away from native eelgrass (Zostera marina).
Also see b. above.
e. List all noxious weeds and invasive species known to be on or near the site.
The Washington Department of Fish and Wildlife has classified Z. japonica growing on
commercial aquaculture sites as a "Class C" noxious weed (Pleus 2012). This category is
for abundant, widespread non·native species that are difficult to control. The primary
concern with Z. japonica in relation to shellfish aquaculture is that it occurs on mid-intertidal
areas that were previously bare mud and sand flats. Z. japonica can potentially grow to the
extent that shellfish planting and harvesting cannot be done successfully (Fisher et al.
2011). In addition, extensive Z. japonica can reduce water flow by up to 40% in comparison
to bare mudflats (Tsai et al 2010). Filter-feeding species, including geoduck, could have
their growth or survival affected by this reduction. Given the WDFW classification of Z.
japonica, any loss at the site could be viewed as a positive. However, this classification
does not necessarily mean that Z. japonica presence is detrimental from the perspective of
ecosystem structure and function.
5. Animals [help] a. List any birds and other animals which have been observed on or near the site or are
known to be on or near the site.
Examples include: birds: hawk, heron, eagle, songbirds, other:
mammals: deer, bear, elk, beaver, other:
fish: bass, salmon, trout, herring, shellfish, other ________
See Attachment A1, “Biological Evaluation, Marine Surveys and Assessments –
10/28/13, in particular Section II, Pages 9-12, and Attachments 1 through 4 to that
Evaluation.
b. List any threatened and endangered species known to be on or near the site.
The following fish, marine mammal, and bird species listed under the Endangered Species
Act may occur, or have critical habitat within the proposed action area:
Puget Sound Chinook
Hood Canal Summer-run Chum
Puget Sound Steelhead
Bull Trout
Yelloweye Rockfish

6. Energy and Natural Resources [help]
a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet
the completed project's energy needs? Describe whether it will be used for heating,
manufacturing, etc.
Diesel or gasoline powered small engines will be used to power vessels and harvesting
equipment during the planting, growing and harvesting phases.
b. Would your project affect the potential use of solar energy by adjacent properties?
If so, generally describe.
No.
c. What kinds of energy conservation features are included in the plans of this proposal?
List other proposed measures to reduce or control energy impacts, if any:
Because the energy use connected with the Project in minimal, there are no specific
conservation measure planned for the Project
7. Environmental Health [help] a. Are there any environmental health hazards, including exposure to toxic chemicals, risk
of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal?
If so, describe.
1) Describe any known or possible contamination at the site from present or past uses.
There is no known contamination or possible contamination at the site from present or
past uses. Log Item 36

2) Describe existing hazardous chemicals/conditions that might affect project development
and design. This includes underground hazardous liquid and gas transmission pipelines
located within the project area and in the vicinity.
There are no known existing hazardous chemicals/conditions that might affect project
development and design.
3) Describe any toxic or hazardous chemicals that might be stored, used, or produced
during the project's development or construction, or at any time during the operating life
of the project.
The only toxic chemicals anticipated to be stored or used in connection with the Project
are gasoline and diesel fuels for operating land based vehicles, harvest vessels, air
pumps, and water pumps. No toxic chemical will be produced by development or
operation of the Project.
4) Describe special emergency services that might be required.
The only special emergency services that might be required in connection with the
Project would be oil spill response and cleanup. Such services are provided through the
Washington Department of Ecology, and for the Project would most likely be provided by
the WSDOE response team based in Olympia, which provides year- round, statewide,
24-hour a day response services.
5) Proposed measures to reduce or control environmental health hazards, if any:
Land vehicles (e .g. all-terrain vehicles or trucks) shall be washed in an upland area such
that wash water is not allowed to enter any stream, waterbody, or wetland. Wash water
shall be disposed of upland in a location where all water is infiltrated into the ground (i.e.,
no flow into a waterbody or wetland). Land vehicles shall be stored, fueled, and
maintained in a vehicle staging area located 150 feet or more from any stream,
waterbody, or wetland.
For boats and other gas-powered vehicles or power equipment that cannot be fueled in a
staging area 150 ft. away from a waterbody or at a fuel dock, fuels shall be transferred in
Environmental Protection Agency (EPA)-compliant portable fuel containers 5 gallons or
smaller at a time during refilling. A polypropylene pad or other appropriate spill protection
and a funnel or spill-proof spout shall be used in the event of a spill. A spill kit shall be
available and used in the event of a spill. All spills shall be reported to the Washington
Emergency Management Office at (800) 258-5990. All waste oil or other clean-up
materials contaminated with petroleum products shall be properly disposed of off-site.
All vehicles operated within 150 feet of any stream, waterbody, or wetland shall be
inspected daily for fluid leaks before leaving the vehicle staging area. Any leaks detected
shall be repaired in the vehicle staging area before the vehicle resumes operation and
documented in a record that is available for review on request by any regulatory or
enforcement personnel.
Except as to water-borne boats and vessels, the direct or indirect contact of toxic
compounds including creosote, wood preservatives, paint, etc. with the marine
environment shall be prevented. For water-borne boats and vessels, all paints and other
Log Item 36

compounds coming into contact with the water will be approved for such use under all
applicable rules and regulations.
b. Noise 1) What types of noise exist in the area which may affect your project (for example:
traffic, equipment, operation, other)?
The uplands neighboring the proposed Smersh geoduck farm are rural residential, and they
are zoned as shoreline residential under the current Shoreline Master Plan for Jefferson
County. There are numerous single‐family residential houses in the Shine neighborhood
which is bordered on the north side by the heavily trafficked State Route (SR) 104. Between
6,000 and 22,000 vehicles pass the Shine neighborhood each day on SR 104 (15,000
average annual daily trips) traveling at 60 miles per hour (WSDOT 2017). Existing noise in
the area includes that which is typically found associated with water‐dependent activities
(e.g., boat use), residential uses (e.g., vehicle use, lawn mowers, beach walking), and
vehicular traffic. Using the standard that 10 percent of the average annual daily traffic
represents hourly average traffic (WSDOT 2018) leads to 1,500 vehicles per hour passing
near the Shine neighborhood on SR 104. At 60 mph the sound from vehicle traffic is
approximately 75 dBA at 50 feet (WSDOT 2018). This sound level attenuates to
approximately 45 dBA at 800 feet which is approximately the halfway point between the
Smersh parcel and SR 104. The estimated noise level based on population density is
approximately 40 to 45 dBA (FTA 2006).
Measurements of ambient underwater noise were recorded at the Hood Canal Bridge in
2004. Median background peak sound pressure was between 118.2 and 137.5 dBPEAK re 1
μPa and median root mean squared (RMS) levels were 115 and 135 dBRMS re 1 μPa
(Battelle 2005).
2) What types and levels of noise would be created by or associated with the project on a
short-term or a long-term basis (for example: traffic, construction, operation, other)? Indi-
cate what hours noise would come from the site.
Noise‐generating elements of the proposed project are consistent with existing use of the
surroundings (small boat use and walking on the beach). Both airborne and underwater
noise would be generated from the proposed project when boats are used to access the
project site and during the operation of pumps for harvest on a 5‐ to 7‐year cycle.
The proposed project does not include the use of heavy equipment. Access to the site
would occur about once a month, and more frequently during limited periods for activities
such as planting or harvesting. Access would be via the upland parcels or via boat. The
outboard motors typically used on boats used for aquaculture typically create a noise level
of about 60 dBA at 50 feet (Berger et al. 2010). However, once at the site, boat engines
would be turned off until employees are ready to leave. Small diesel or gas‐powered
water pumps with hoses would be used to harvest the geoducks for several days every 5
to 7 years. While noise levels of the water pumps have not been directly measured, they
are considerably quieter than the outboards, referenced above, that produce a sound level
of 60 dBA at 50 feet. Based on an ambient noise level of approximately 40 dBA to 45 dBA,
terrestrial noise associated with the proposed project is expected to attenuate to ambient
conditions 199 to 285 feet from the pumps. The landward margin of the geoduck planting
area is approximately 160 feet from the ordinary high water line, leading to the conclusion
that nearby residents will be exposed to only slight increases in noise if they approach within
close proximity to the shoreline near the project site. Log Item 36
Page 21 of 218
SEPA Environmental checklist (WAC 197-11-960) Responses Revised May 26, 2020 Page 14 of 22
The loudest noise source proposed for the project) is expected to increase noise levels by
15 dBA to 20 dBA above ambient noise levels (assuming 60 dBA produced by the water
pump and 40 to 45 dBA ambient noise).
Underwater noise would also be generated from the motors on boats used to transport gear
and personnel to the project area and the small engines used for the water pumps during a
geoduck harvest.
For more information on anticipated noise generation, see BDN Smersh Farm Habitat
Management Plan and No Net Loss Report – Confluence Environmental Company – June,
2018 (See Attachment E, pages 9-12.)
3) Proposed measures to reduce or control noise impacts, if any:
There is no evidence that increases in either airborne or underwater noise from the use of
boat motors or water pumps associated with the rearing and harvest of geoducks would
result in negative effects to fish and wildlife species. Noise resulting from aquaculture
operations throughout Washington State was reviewed with respect to potential effects to
fish, marine mammals, and birds listed as threatened or endangered under the Endangered
Species Act (NMFS 2009, USFWS 2009, NMFS 2011). These reviews found that noise
levels did not exceed disturbance thresholds that would affect foraging, migration,
reproduction, or fitness for any of the ESA‐listed species in Puget Sound. The proposed
shellfish aquaculture operation in Squamish Harbor would not significantly alter noise above
existing background conditions. Therefore, harvest operations are not anticipated to
increase underwater noise to a level that will result in a loss of ecological functions, and no
specific measures are planned or needed to reduce or control the already minimal noise
impacts. Nonethless, applicant plans to locate the water pumps used during harvesting in
an insulated box, thereby decreasing pump noise.
8. Land and Shoreline Use [help] a. What is the current use of the site and adjacent properties? Will the proposal affect current land
uses on nearby or adjacent properties? If so, describe.
The site is currently vacant tidelands, located on a heavily altered shoreline in a medium‐
density, residential neighborhood. The shoreline has been altered by rip rap hardening.
There is a concrete boat ramp and gravel parking lot on the adjacent public property.
Riparian trees have been removed from a number of the adjacent properties to increase
private views, and a paved roadway is adjacent to the shoreline for approximately 1 mile
next to the Smersh parcel.
The uplands neighboring the proposed Project are rural residential, and they are zoned as
shoreline residential under the current Shoreline Master Plan for Jefferson County. There
are numerous single‐family residential houses in the Shine neighborhood which is bordered
on the north side by the heavily trafficked State Route (SR) 104.
The proposed project will not affect current land uses on nearby or adjacent properties.

b. Has the project site been used as working farmlands or working forest lands? If so, describe.
How much agricultural or forest land of long-term commercial significance will be converted to
other uses as a result of the proposal, if any? If resource lands have not been designated, how
many acres in farmland or forest land tax status will be converted to nonfarm or nonforest use?
No.
1) Will the proposal affect or be affected by surrounding working farm or forest land normal
business operations, such as oversize equipment access, the application of pesticides, tilling,
and harvesting? If so, how:
No.
c. Describe any structures on the site.
There are no structures currently on the site
d. Will any structures be demolished? If so, what?
No.
e. What is the current zoning classification of the site?
RR-5 – Rural Residential
f. What is the current comprehensive plan designation of the site?
RR-5 Rural Residential
g. If applicable, what is the current shoreline master program designation of the site?
Aquatic – Shoreline Residential
h. Has any part of the site been classified as a critical area by the city or county? If so, specify.
Yes. Portions of the Project Area are classified as Wetlands Critical Area, FEMA Flood Zone
Critical Area, Seismic Hazard Critical Area, Seawater Intrusion Protection Zone, and Critical
Aquifer Recharge Area.
i. Approximately how many people would reside or work in the completed project?
12-25 workers will work in 5-hour shifts to plant PVC tubes during the geoduck planting
phase, which will take place once every 5-7 years. The work will be sporadic, depending on
tides and weather, beginning in the spring and lasting through the fall. After planting, weekly
site inspections will be conducted by 2-4 BDN employees walking the tidelands and
Log Item 36
Page 23 of 218
SEPA Environmental checklist (WAC 197-11-960) Responses Revised May 26, 2020 Page 16 of 22
surrounding areas at low tide. 6-12 months after planting, the PVC tubes will be removed by
hand, again by 12-25 workers working in 5-hour shifts. This work will also be sporadic,
depending on tides and weather, and will be done from winter to early summer.
Usually, harvesting will begin between four to seven years alter planting; the exact timing of
harvesting will depend on a variety of environmental and economic factors. The total harvest
window is expected to be 1 year. Dive harvests will employ 1 diver and 2
support workers in the skiff. Dive harvesting will usually last up to S hours each day for two
divers. Beach harvests will employ 2 workers on the beach and 2 support workers on the
skiff.
j. Approximately how many people would the completed project displace?
None.
k. Proposed measures to avoid or reduce displacement impacts, if any:
None planned, as there will be no displacement.
L. Proposed measures to ensure the proposal is compatible with existing and projected land
uses and plans, if any:
See Attachments C through E for descriptions of the compatability of the project with existing
and projected land uses and plans.
m. Proposed measures to reduce or control impacts to agricultural and forest lands of long-term
commercial significance, if any:
None are required, as there are no anticipated impacts to agricultural and forest lands of
long-term commercial significance.
9. Housing [help] a. Approximately how many units would be provided, if any? Indicate whether high, mid-
dle, or low-income housing.
No housing units will be provided.
b. Approximately how many units, if any, would be eliminated? Indicate whether high,
middle, or low-income housing.

SEPA Environmental checklist (WAC 197-11-960) Responses Revised May 26, 2020 Page 17 of 22
a. What is the tallest height of any proposed structure(s), not including antennas; what is
the principal exterior building material(s) proposed?
No structures are proposed. The only artificial objects that will be placed on the subject
tidelands are PVC plastic 4” diameter by 10” long geoduck planting tubes, which will be
placed into the sandy substrate at an approximate density of 1 tube per square foot with 3” to
5” of the tube exposed above the substrate.
These tubes will be stored in open piles or stacks in areas in the northern half of related
upland parcel 8213444032 currently covered by grass or small shrubs. Total coverage of
these piles at any one time will be not more than 4,000 square feet, and the piles will not
exceed 7 feet in height.
b. What views in the immediate vicinity would be altered or obstructed?
15 to 20 homes have unobstructed view of the proposed geoduck planting area when nearby
trees are in the leaf‐off condition. The estimate of 15‐20 homes with unobstructed
views will be reduced during the summer when trees have a cover of leaves that are likely to
more fully block views. For more detail on potential and actual visual obstruction, see
Attachment C, BDN Smersh Farm Visual Assessment‐, Confluence Environmental Company
– October, 2019.
Tubes stored on related Parcel 8213444032, or vehicles temporarily parked there may be
visible to a minor degree from three nearby homes.
c. Proposed measures to reduce or control aesthetic impacts, if any:
The proposed project will be visible for only short duration during very low tides. Geoduck
PVC tubes will initially be black or white, and will quickly take on a natural color due to
colonization by aquatic flora and fauna, such that from a distance they will blend in with other
beach elements, and even close up will not be a significant visual disruption to the natural
landscape. Maintenance will occur monthly, and after any storm events, to ensure farm is tidy
and tubes have not become dislodged. While not in use, equipment will be stored off-site.
Piles of stored tubes on upland parcel 8213444032 will be restricted to 7 feet in height and no
more than 4000 square feet of total coverage. (See Addendum M-2)
11. Light and Glare [help]
a. What type of light or glare will the proposal produce? What time of day would it mainly
occur?
No work will be performed at night other than checking of PVC tubes and other gear by
beach maintenance workers on an as-needed basis (see Item A. 11. above for a more
detailed description of this work.) Beach maintenance workers will use individual LED
headlamps (with an output of 6000 lumens or less) to provide a narrow beam of individual
lighting for that worker. Overall, the project will not produce any significant light or glare that
will be visible to upland owners.
No vessel operations will be performed at night. Log Item 36

b. Could light or glare from the finished project be a safety hazard or interfere with views?
No.
c. What existing off-site sources of light or glare may affect your proposal?
None.
d. Proposed measures to reduce or control light and glare impacts, if any:
Not applicable.
12. Recreation [help]
a. What designated and informal recreational opportunities are in the immediate vicinity?
The only nearby designated recreational opportunity is the neighboring park, which is primarily
a boat launching ramp, usable at high tide only, with an associated gravel parking lot. The
main informal recreational activites are beach walking by resident and visitors at low tide, and
use of the water over the project at high tide by recreational boaters.
b. Would the proposed project displace any existing recreational uses? If so, describe.
The boat ramp is only useable during high tide, when the geoduck tubes would be submerged,
so there is no displacement of that use. There will be no impacts to beach access as the
project is located on private tidelands that are not currently accessible by the public. The
project will not impact recreational boating use in any significant way. Dive harvest vessels will
be small, and moored over the project tidelands in such a way as to not significantly interfere
with other vessels in the area.
c. Proposed measures to reduce or control impacts on recreation, including recreation
opportunities to be provided by the project or applicant, if any:
None are proposed, as none are necessary
13. Historic and cultural preservation [help]
a. Are there any buildings, structures, or sites, located on or near the site that are over 45 years
old listed in or eligible for listing in national, state, or local preservation registers ? If so,
specifically describe.
No such structures or sites exist in the project area.
b. Are there any landmarks, features, or other evidence of Indian or historic use or occupation?
This may include human burials or old cemeteries. Are there any material evidence, artifacts, or
areas of cultural importance on or near the site? Please list any professional studies conducted
at the site to identify such resources.
Log Item 36

No landmarks, features, or other evidence of Indian or historic use or occupation are known to
exist at the site.
c. Describe the methods used to assess the potential impacts to cultural and historic resources on
or near the project site. Examples include consultation with tribes and the department of
archeology and historic preservation, archaeological surveys, historic maps, GIS data, etc.
No consultations or studies have been undertaken, since the project consists of bare tidelands
with no evidence of any prior habitation or human use.
The Corps of Engineers has determined that cultural resource surveys are not required for this
project.
d. Proposed measures to avoid, minimize, or compensate for loss, changes to, and disturbance to
resources. Please include plans for the above and any permits that may be required.
No specific measures are proposed.
14. Transportation [help] a. Identify public streets and highways serving the site or affected geographic area and describe
proposed access to the existing street system. Show on site plans, if any.
Land access to the project site is via Shine Road, a public street running parallel to the
shoreline and serving the adjacent tidelands and upland properties. Public Highway SR 104
runs roughly parallel to the shoreline and at the location of the project is about ¼ mile north of
Shine road.
b. Is the site or affected geographic area currently served by public transit? If so, generally
describe. If not, what is the approximate distance to the nearest transit stop?
The site is not directly served by public transit, but the Jefferson Transit Route #7, Poulsbo, has
a bus stop approximatsly 1.2 miles to the East at the western end of the Hood Canal bridge.
c. How many additional parking spaces would the completed project or non-project proposal
have? How many would the project or proposal eliminate?
The project will not require any additional parking spaces, and will not eliminate any existing
parking spaces.
d. Will the proposal require any new or improvements to existing roads, streets, pedestrian, bicycle
or state transportation facilities, not including driveways? If so, generally describe (indicate

were used to make these estimates?
During active planting and beach harvest activites, about ten to twenty passenger vehicle trips,
and one or two truck trips (to deliver or load geoducks or other project materials) will be
generated each day. During beach inspection periods, one to two passenger vehicle trips will
be generated each day. During waterborne harvesting, one or two truck trips (to deliver or load
geoducks or other project materials) will be generated each day. No data or transportation
models were used to make these estimates.

Addendum M-1 – Use of Upland Parcel 970200001
Description of Property and Potential Usage.
This parcel is owned by applicant James Smersh. It consists of .29 acres of unimproved land,
zoned Rural Residential RR-5, Assessor’s Land Use Code 9100-Vacant Land. It is accessed at
its northwest corner via a recorded easement across the adjacent parcel 970200002 immediately

to the west, owned by Bruce A. Olsen. That easement is roughly co-extensive with the roadway
visible to the left of the parcel in the above photo.
The Google Earth Imagery Date for this photo is 5/13/2018, and shows it being used by the
applicant for storage of three small personal watercraft in the upper northeast area, and storage
by BDN, LLC of white PVC geoduck planting tubes connected with existing nearby BDN
aquaculture operation. There are two BDN trailers parked temporarily on the property as shown
to the left of the PVC tubes. Since the date of the photo, all BDN items have been removed from
the property, and it is once again being used only for storage of the personal watercraft.
Because BDN has now acquired a nearby parcel (821344064) for storage and staging as
described elsewhere in this SEPA Checklist, there will be no future storage of BDN tubes or
other materials on parcel 970200001. It will be used solely as a secondary parking area for
activities related to the operation of the proposed aquaculture project.
There will be no clearing, grading or construction of any kind on this parcel by BDN, LLC, and
no impervious surfaces will be created. This property is not within 150 feet of any waterbody, is
not within 150 feet of any known Type F, N or S streams, is not a wetland, and is not in a
Shoreline Jurisdiction. It is not within a FEMA Flood Zone, Landslide Hazard Area, Soil Erosion
Area or Soil Seismic Area. It is within a Critical Aquifer Recharge Area and a Saltwater
Intrusion Protection Zone, but no activities proposed on the property will in any way impact the
parcels aquifer or saltwater intrusion functions or characteristics.
The only BDN use anticipated for this parcel will be as follows:
1) Parking of one or two passenger vehicles or light trucks on the parcel for 1-2 hours once
weekly for regular beach inspections of geoduck gear.
2) Parking of one or two passenger vehicles or light trucks on the parcel in connection with
emergency responses per the applicable Gear Management Plan. From prior BDN
experience in the area, such emergency responses occur on less than five days per year,
typically in the winter and sometimes at night.
3) Parking of a maximum of 6 passenger vehicles or light trucks on the parcel for no more
than 5 hours per day during planting or harvesting activities. However, it is anticipated
that BDN parcel 821344064 will be the primary parking and staging area for these
operations, such that related parking on this parcel will take place an average of less than
ten days per year.
Cumulative Impacts of the Use of This Parcel by BDN
By far the dominant vehicle traffic impact on the area is from the 24-hour-per-day, seven-days-
per-week vehicle traffic on Shine Road, which passes a few hundred feet from both the existing
and proposed BDN projects. The addition of the very few additional vehicle trips and parking
activities as described in the annotated site plan (BDN004R) will have at most a tiny cumulative
effect on the project area when compared to the constant visual and noise impact from Shine
Road and the surrounding feeder roads, especially since regular parking will be provided for all
beach workers on parcel 821344064 as necessary.

The SMP defines “Cumulative impacts” or “cumulative effects” as “the combined impacts of a
proposed development action along with past impacts and impacts of reasonably foreseeable
future development actions. (JCC 18.25.100(3)(aa)). “Reasonably foreseeable” is defined as
“predictable by an average person based on existing conditions, anticipated build-out, and
approved/pending permits.” (JCC 18.25.100(18)(d))
Similarly, the National Environmental Policy Act (“NEPA”) requires the consideration of the
cumulative impacts of the Project, which include both direct effects, defined as those impacts
"caused by the action and occur[ing] at the same time and place" and indirect effects, which are
impacts "caused by the action and are later in time or farther removed in distance, but are still
reasonably foreseeable." 40 C.F.R. § 1508.8. Note that although indirect effects may be removed
in distance from the proposed action, they nonetheless must be caused by that action; i.e., there
must be a "reasonably close relationship" between the environmental effect and alleged cause.
Department of Transportation v. Public Citizen, 541 U.S. 752, 767 (2004).
The miniscule additional vehicle traffic generated by infrequent parking of vehicles on the parcel
as described above will have no significant cumulative impact on the areas surrounding the
parcel, either nearby or distant, while facilitating an aquaculture usage that is preferred under
Washington law (RCW 90.58.020.)

Addendum M-2 – Upland Parcel 821344064
Description of Property and Potential Usage.
This parcel is owned by BDN, LLC (“BDN”.) It consists of 1.26 acres of unimproved land,
zoned Rural Residential RR-5, Assessor’s Land Use Code 9100-Vacant Land. It is accessed at
its southwest corner via a 30’ wide recorded easement 821344064 (Vol 2 Short Plats, Page 166,
records of Jefferson County) across the adjacent parcel 821344029 to the south, owned by Alona

J. Cowing, and the along parcel 821344032 to the south of 821344029, owned by Mary
Cameron, ending at Shine Road. That easement is roughly co-extensive with the dirt roadway
visible to the lower left of the parcel in the above photo.
The Google Earth Imagery Date for this photo is 5/13/2018, and shows it as vacant land covered
with grasses, small bushes, and three medium sized conifer trees at its northern end.
The usage proposed by BDN of this parcel will be:
1) Storage during BDN geoduck aquaculture planting, growing and harvest activities of
4” in diameter by 10" long PVC geoduck planting tubes. These tubes will be stored in
open piles or stacks in areas in the northern half of the parcel currently covered by grass
or small shrubs. Total coverage of these piles at any one time will be not more than
4,000 square feet, and the piles will not exceed 7 feet in height. These piles will allow
free draining of precipitation to the unimproved land beneath them, and will not
significantly compact the surface of the parcel.
The lack of release of microplastics from aquaculture gear is supported by available data
for the Salish Sea, showing lower levels of microplastics in water and sediment in areas
of active shellfish aquaculture compared with urban embayments. Similar claims about
phthalate plasticizers are unsupportable because such plasticizers are used in flexible
PVC, not rigid PVC. Does Plastic Shellfish Gear Increase Microplastic And Chemical
Exposures? Schoof, Rosalind Ramboll, Environ US Corporation, Abstracts, 71st Annual
Shellfish Growers Conference and Tradeshow Pacific Coast Shellfish Growers
Association National Shellfisheries Association Pacific Coast Section Welches, OR,
September 19-21, 2017. There are no known studies indicating that the amount of PVC
components that might be introduced into the environment through the storage of PVC
Tubes on the property has any adverse environmental effect, immediate or cumulative.
2) Parking on the parcel of one to two light trucks and/or light trailers used for
delivering or removing materials to or from parcel.
3) Parking of one or two passenger vehicles or light trucks on the parcel for 1-2 hours
once weekly for regular beach inspections of geoduck gear.
3) Parking of one or two passenger vehicles or light trucks on the parcel in connection
with emergency responses per the applicable Gear Management Plan. From prior BDN
experience in the area, such emergency responses occur on less than five days per year,
typically in the winter and sometimes at night.
4) Parking of a maximum of 6-8 passenger vehicles or light trucks on the parcel for no
more than 5 hours per day during planting or harvesting activities.
There will be no clearing, grading or construction of any kind on this parcel by BDN, LLC, and
no impervious surfaces will be created. This property is not within 150 feet of any waterbody, is
not within 150 feet of any known Type F, N or S streams, is not a wetland, and is not in a
Shoreline Jurisdiction. It is not within a FEMA Flood Zone, Landslide Hazard Area, Soil Erosion
Area or Soil Seismic Area. It is within a Critical Aquifer Recharge Area and a Saltwater

parcels aquifer or saltwater intrusion functions or characteristics.
Cumulative Impacts of the Use of This Parcel by BDN
Materials stored on the parcel will be visible only to the three neighbors immediately adjacent to
the parcel. The small piles of black mesh tubes will be unobtrusive and the small amount of
associated vehicle traffic will be much, much less from a noise and pollution standpoint than the
high volume of 24-hour-per-day, seven-days-per-week vehicle traffic on the heavily used SR 104
highway immediately adjacent to the parcel.
The SMP defines “Cumulative impacts” or “cumulative effects” as “the combined impacts of a
proposed development action along with past impacts and impacts of reasonably foreseeable
future development actions. (JCC 18.25.100(3)(aa)). “Reasonably foreseeable” is defined as
“predictable by an average person based on existing conditions, anticipated build-out, and
approved/pending permits.” (JCC 18.25.100(18)(d)).
Similarly, the National Environmental Policy Act (“NEPA”) requires the consideration of the
cumulative impacts of the Project, which include both direct effects, defined as those impacts
"caused by the action and occur[ing] at the same time and place" and indirect effects, which are
impacts "caused by the action and are later in time or farther removed in distance, but are still
reasonably foreseeable." 40 C.F.R. § 1508.8. Note that although indirect effects may be removed
in distance from the proposed action, they nonetheless must be caused by that action; i.e., there
must be a "reasonably close relationship" between the environmental effect and alleged cause.
Department of Transportation v. Public Citizen, 541 U.S. 752, 767 (2004).
The on-site storage of PVC tubing, and the small amount of related vehicle traffic generated by
parking of vehicles on the parcel as described above will have no significant cumulative impact
on the areas surrounding the parcel, either nearby or distant, while facilitating an aquaculture
usage that is preferred under Washington law (RCW 90.58.020.)

Addendum M-3 – Hicks Park
Description of Property and Potential Usage.
This approximately 1 acre Jefferson County Park is located at 1090 Shine Rd, Port Ludlow, WA
98365, adjacent to the proposed BDN project to the west. It has a boat ramp, vault toilet, BBQ
grill, two picnic tables, and a campfire ring. No alcohol is allowed in the park pursuant to RCW
66.44.100.
BDN does not propose to use the boat ramp at this facility for any purpose. The only potential
use of Hicks park would be parking of one or two passenger vehicles or light trucks on the parcel
for 1-2 hours once weekly for regular beach inspections of geoduck gear, and possible parking of
one or two passenger vehicles or light trucks on the parcel in connection with emergency
responses per the applicable Gear Management Plan. From prior BDN experience in the area,
such emergency responses occur on less than five days per year, typically in the winter and
sometimes at night.
BDN personnel will be instructed not to use the parking facilities at Hicks Park if there are any
other members of the public present there using the facilities in any way. In such cases, they will
be instructed to park either at nearby parcel 970200001, owned by Applicant (See Addendum M-
1) or at parcel 821344064, owned by BDN.

with use of the park by members of the public. On average, between 275 and 325 vehicles per
day pass by the park on the adjacent Shine Road (Shine Road Speed Limit and Traffic Study,
October 2018, Jefferson County Public Works.) The Noise and pollution generated by traffic on
the adjacent Shine Road dwarfs the miniscule addition of one or two weekly passenger vehicle
visits to the park for 1-2 hours.

Addendum M-4 – Use of Shine Tidelands State Park Boat Launch Ramp
Description of Property and Potential Usage.
This 249 acre seasonal day use State Park is located at Shine Tidelands State Park Road, Port
Ludlow, WA. At its extreme south end, adjacent to the northwestern abutment of the Hood
Canal Bridge, is a paved public boat launch ramp.
The only part of the park that may be used by BDN is the boat launch area. BDN will use the
ramp for the loading and launching of a small watercraft (less than 30 feet.) One light truck
vehicle will tow the watercraft to the launch ramp, and will launch and retrieve it. Launching
and retrieving will require 15 minutes or less.
During planting activities, another light truck vehicle will tow an accompanying open trailer of
supplies (with 5’ sides) to be loaded into the boat and used in the planting of parcel 721031007.
Planting related activities will involve at most one daily launching and retrieval of the vessel, and
Shine Tidelands State Park
Boat Launch Ramp
Log Item 36

BDN, LLC – SEPA Checklist Addendum M-4
Page - 2
1-3 supply trips by the accompanying trailer. Planting activities will occur once per year,
typically in June or July, over a period of 20-25 days.
During harvesting activities, another light truck vehicle will tow an accompanying open trailer
(with 5’ sides) to be loaded at the launch ramp with harvested geoducks from parcel 721031007.
Harvesting related activities will involve at most one daily launching and retrieval of the vessel,
and 1-3 trips by the accompanying trailer. Harvesting activities will occur between four and
seven years after an area of parcel 721031007 has been planted, and that planted area will
typically be harvested over a one year period. Harvesting activities at this location will occur
only during daylight hours, over a period of about 5 hours per day, three days a week during that
one year period.
From usage connected with other previously approved BDN activities, it is clear that the Shine
Tidelands State Park boat launch facility has very low public usage, due to the lack of a dock, a
poorly configured boat launch ramp, and bad currents at the point of launching. No public use of
this area has ever been observed while BDN has conducted any activities there. Nonetheless,
BDN personnel will be instructed to allow all members of the public priority in using the ramp.
If anyone is present at the launch area when BDN arrives, the BDN personnel will wait until that
party completes their use of the ramp before commencing any BDN operations there.
Cumulative Impacts of the Use of This Parcel by BDN
The SMP defines “Cumulative impacts” or “cumulative effects” as “the combined impacts of a
proposed development action along with past impacts and impacts of reasonably foreseeable
future development actions. (JCC 18.25.100(3)(aa)). “Reasonably foreseeable” is defined as

The potential limited use of the Shine Tidelands State Park boat launch facility as described
above will have virtually no cumulative impact on the park or any other areas, either nearby or
distant. No proposed activities at this location will in any way impact any nearby waterbodies or
streams in any way that differs from impacts by the general public using the park. No BDN
personnel will ever interfere in any way with use of the ramp or the other areas of the park by
members of the public. On average, between 15,000 to 22,000 vehicles per day traverse the
adjacent Hood Canal Bridge (Study of SR104:US101 to SR3 and SR3:SR104 to SR305,
WSDOT.) The Noise and pollution generated by traffic on the adjacent Hood Canal Bridge
dwarfs the miniscule addition of the above-described vehicle and trailer trips.

Use the quantities reported in this worksheet to determine which minimum requirements apply to your project
and what forms will be required using the “Flow Chart for Determining Minimum Requirements.”
Step 1
Yes no
All projects must read and complete the Stormwater Calculation Worksheet.
Small Projects may submit the Worksheet S Small Project Certification sheet. Applicants who are able to sign the
certification may STOP HERE. Submit the Stormwater Calculation Worksheet and Worksheet “S” with your appli-
cation. No additional submittal is necessary.
Step 2
Step 2.1
Step 2.1 Medium Projects must complete worksheets A1, B1, and C or equivalent. Large Projects refer to Worksheet L to
determine applicable worksheets are required or if a state -licensed engineer must prepare the submittal.
A Note on Engineered Stormwater Submittal:
-Many applicants complete stormwater submittal forms independently without professional expertise. For example, full
dispersion, if feasible on the site (See Worksheet C), is typically easiest to implement for many different surface types suc h as
roof, driveway, patio etc.
-Applicants may opt to submit an engineered stormwater plan even if it isn’t required. This option may be attractive to those who
are unsure how some of the requirements will be achieved on the site.In some instances, engineering will be required. Certain
Large projects must be engineered (See Worksheet L). Gathering information on infiltration feasibility may need an engineer ’s
expertise. Or, sites with greater than 15% slopes may require applicants hire a geologist to recommend if a drainage method i s
appropriate. Discharging directly to a marine water via tightline must be engineered. If you cannot do full dispersion on par cels
larger than 5 acres, engineering is required. In other instances, site constraints will require an engineered design.
-Jefferson County staff may assist by providing and/or explaining Department of Ecology Stormwater Management Manual
The project requires or the applicant elects to submit an engineered stormwater plan. The plan is attached hereto
with minimum requirement narrative, drawings, calculation, modeling output, construction pollution prevention
plan, and site plan.
Circle one:
Step 3
If you answered YES above, STOP, no further submittal is required. Otherwise, proceed with the following steps.
Complete Worksheet A1 Medium/Large Project Report and Stormwater Site Plan or equivalent.
Step 3.1 Complete Worksheet C to determine which BMPs are possible and appropriate for your site. Circle the first BMP
that is feasible (i.e. none of the infeasibility criteria is checked) for each surface type. Circle the corresponding
BMP on Worksheet A1.
Step 4 Complete Worksheet B1 Medium/Large Project Construction Pollution Prevention Plan and Worksheet B2
Construction Site Plan or equivalent.
A Note on Commercial Projects:
•Jefferson County Public Works (JCPW) reviews commercial projects and charges a review fee. JCPW may charge additional
fees for any required inspections.
•Any commercial projects proposing infiltration facilities may complete Worksheet E —Infiltration Test. Grain size analysis may
be used instead of PIT. Commercial projects may elect to use BMP T5.10A and would not need a PIT, just a soil evaluation.
•Any development for cottage industries may require a commercial public works review if full dispersion is infeasible.

DETERMINING STORMWATER MANAGEMENT REQUIREMENTS: This stormwater calculation worksheet should be completed first to
classify the proposal as “small,” “medium,” or “large.” The size determines whether a Stormwater Site Plan is re quired in
conjunction with a stand-alone stormwater management permit application, building permit application, or other land use approval
application that involves stormwater review. The basic information will also be helpful for completing a Stormwater Site Plan, if
required.
Land-disturbing activity is any activity that results in movement of earth, or a change in the existing soil cover (both vegetative and
non-vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to clearing, grading, filling,
excavation, and compaction associated with stabilization of structures and road construction.
Native vegetation is vegetation comprised of plant species, other than noxious weeds, which reasonably could have been expected
to naturally occur on the site. Examples include species such as Douglas fir, western hemlock, western red cedar, alder, big -leaf
maple, and vine maple; shrubs such as willow, elderberry, salmonberry, and salal; herbaceous plants such as sword fern, foam
flower, and fireweed.

CONSTRUCTION STORMWATER POLLUTION PREVENTION
Best Management Practices (BMPs) Fact Sheet
For “small” projects (as determined through the Stormwater Calculation Worksheet), submit Worksheet
“S” Small Project Certification. Additionally, the applicant shall consider the twelve Construction
Stormwater Pollution Prevention elements and implement applicable BMPs. A set of useful BMPs for
typical rural residential construction is attached. There is no additional submittal required as part of the
permit application.
For “medium” and “large” projects, applicants must submit a Construction Stormwater Pollution
Prevention Plan (SWPPP) and a Stormwater Site Plan (applicants may use Worksheet B1 or equivalent).
The following twelve elements must be considered for Construction Stormwater Pollution Prevention
before and during the construction phase of the project:
1.Mark Clearing Limits 7.Protect Drain Inlets
2.Establish Construction Access 8.Stabilize Channels and Outlets
3.Control Flow Rates 9.Control Pollutants
4.Install Sediment Controls 10.Control De-Watering
5.Stabilize Soils 11.Maintain Best Management Practices
6.Protect Slopes 12.Manage The Project
Each of the twelve elements is described in more detail below:
1.Mark Clearing Limits
By minimizing the limits of clearing on the site, a builder can minimize stormwater runoff and provide
effective control of pollution.
2.Establish Construction Access
Much of the sediment that leaves a construction site does so on the wheels of delivery and construction
vehicles that drive off a project site. Construction access must be limited to a single location and a
properly constructed Stabilized Construction Entrance (BMP C105) should be included on the site.
3.Control Flow Rates
Stormwater that leaves a project site unimpeded may exceed the capacity of the existing stormwater
control facilities downstream and may contain sediment that may be deposited as the velocity of the
runoff decreases. Stormwater protection on a construction site should include measures to control the
flow rate of runoff from the site. This can be done by installing a Sediment Trap (BMP C240) or other
measure that will impede the flow of water off a construction site.
4.Install Sediment Controls
In addition to limiting the rate of stormwater flow off a construction site, measures should be put in place
to treat the runoff and remove sediment. Limiting of the cleared area (Element 1) will assist in this effort,
but there will be exposed soils that may move with the runoff. Suggested BMPs for controlling sediment
include Straw Wattles (BMPC235), Brush Barrier (BMP C231), Gravel Filter Berm (BMP C232), and Silt
Fence (BMP C233). Installation of a Sediment Trap (Element 3) is an additional sediment control feature.
Log Item 36
Page 46 of 218
construction Pollution Prevention Page 2 of 3 5/31/2019
5.Stabilize Soils
An additional measure that can minimize sediment transport in runoff is to stabilize soils on the site with
mulch or some other covering. This will limit the amount of soil that is exposed to rainfall, thus limiting the
sediment that could potentially leave the site. BMPs that could be used for this include Mulching (BMP
C121), Nets and Blankets (BMP C122), and Plastic Covering (BMP C123). During periods of dry weather
dust can become a problem and sediment could be transported from the site in high winds. BMP C140
Dust Control should be followed to limit loss of soils in windy conditions.
6.Protect Slopes
If the cleared area includes slopes of 3:1 (Horizontal: Vertical) or steeper, the slopes should be protected
to limit runoff. If the slopes are not protected, rills and gullies may form, transporting sediment to the
lower elevations and potentially off the construction site. The slopes sh ould be graded to minimize
erosion and runoff at the downstream end of the slopes, and runoff should be collected and treated. The
following BMPs could be used Surface Roughening (BMP C130), Interceptor Dike and Swale (BMP
C200), and Pipe Slope Drains (BMP C204).
7.Protect Drain Inlets
Runoff from urban construction sites often discharges into existing stormwater collection systems. Water
enters the collection system through drain inlets. If there are drain inlets downstream of a construction
site, they should be protected using BMP C220 Storm Drain Inlet Protection.
8.Stabilize Channels and Outlets
Any temporary on-site channels or ditches that are used to control runoff should be stabilized to prevent
erosion in the channel. BMP C202 Channel Lining and BMP C209 Outlet Protection should be used.
9.Control Pollutants
The best way to control pollution is to limit the source of pollution. Construction debris should be
maintained in a safe location. Vehicle maintenance on the construction site should be minimized and any
spill should be promptly cleaned up. Concrete spillage should be kept to a minimum and cleaning of the
concrete trucks after they have unloaded should be done in an area that will not drain off site (see BMP
C151 Concrete Handling).
10.Control Dewatering
In some cases, excavation for the foundation or below ground structures will encounter ground water.
This water must be removed (dewatered) from the excavation. Discharge of this ground water must be
treated in a manner that will not cause damage downstream due to flow rates or added pollution. There
are no specific BMP identified for this activity, but the water should be handled with care to assure that
soils or other pollutants are not added to this flow.
11.Maintain BMPs
Installation of the appropriate BMPs is not adequate to completely control stormwater runoff. The BMPs
that have been installed on the project must be inspected and maintained during the duration of the
construction project. In addition, the temporary controls that were installed for construction should be
removed within 30 days of completion of the work. Typically, once construction has been completed, the
temporary facilities are not maintained, and by removing the facilities, it will ensure that these won’t f ail
and discharge water or sediment that had been previously trapped or contained.
12.Manage the Project
Management of a project has four aspects:
1.Phasing construction to prevent transportation of runoff and sediment,
2.Limiting the work during seasons where large amounts of rainfall could be anticipated,
3.Coordination with Utilities and other Contractors, and
4.Inspection and Monitoring.
All of these for aspects are important and must be followed to ensure a project that will have minimal
impact on the environment. Volume II of the Manual contains additional BMPs that could be used on-site.
The applicant is encouraged to review the Manual to see if other BMPs may be applicable to, or more
useful on, a particular site. Log Item 36

Start HERE! A guide to using stormwater forms
Use the quantities reported in this worksheet to determine which minimum requirements apply to your project
and what forms will be required using the “Flow Chart for Determining Minimum Requirements.”
Step 1
Yes no
All projects must read and complete the Stormwater Calculation Worksheet.
Small Projects may submit the Worksheet S Small Project Certification sheet. Applicants who are able to sign the
certification may STOP HERE. Submit the Stormwater Calculation Worksheet and Worksheet “S” with your appli-
cation. No additional submittal is necessary.
Step 2
Step 2.1
Step 2.1 Medium Projects must complete worksheets A1, B1, and C or equivalent. Large Projects refer to Worksheet L to
determine applicable worksheets are required or if a state -licensed engineer must prepare the submittal.
A Note on Engineered Stormwater Submittal:
-Many applicants complete stormwater submittal forms independently without professional expertise. For example, full
dispersion, if feasible on the site (See Worksheet C), is typically easiest to implement for many different surface types suc h as
roof, driveway, patio etc.
-Applicants may opt to submit an engineered stormwater plan even if it isn’t required. This option may be attractive to those who
are unsure how some of the requirements will be achieved on the site.In some instances, engineering will be required. Certain
Large projects must be engineered (See Worksheet L). Gathering information on infiltration feasibility may need an engineer ’s
expertise. Or, sites with greater than 15% slopes may require applicants hire a geologist to recommend if a drainage method i s
appropriate. Discharging directly to a marine water via tightline must be engineered. If you cannot do full dispersion on par cels
larger than 5 acres, engineering is required. In other instances, site constraints will require an engineered design.
-Jefferson County staff may assist by providing and/or explaining Department of Ecology Stormwater Management Manual
The project requires or the applicant elects to submit an engineered stormwater plan. The plan is attached hereto
with minimum requirement narrative, drawings, calculation, modeling output, construction pollution prevention
plan, and site plan.
Circle one:
Step 3
If you answered YES above, STOP, no further submittal is required. Otherwise, proceed with the following steps.
Complete Worksheet A1 Medium/Large Project Report and Stormwater Site Plan or equivalent.
Step 3.1 Complete Worksheet C to determine which BMPs are possible and appropriate for your site. Circle the first BMP
that is feasible (i.e. none of the infeasibility criteria is checked) for each surface type. Circle the corresponding
BMP on Worksheet A1.
Step 4 Complete Worksheet B1 Medium/Large Project Construction Pollution Prevention Plan and Worksheet B2
Construction Site Plan or equivalent.
A Note on Commercial Projects:
•Jefferson County Public Works (JCPW) reviews commercial projects and charges a review fee. JCPW may charge additional
fees for any required inspections.
•Any commercial projects proposing infiltration facilities may complete Worksheet E —Infiltration Test. Grain size analysis may
be used instead of PIT. Commercial projects may elect to use BMP T5.10A and would not need a PIT, just a soil evaluation.
•Any development for cottage industries may require a commercial public works review if full dispersion is infeasible.

STORMWATER CALCULATION WORKSHEET
PARCEL # PROJECT/APPLICANT NAME:
DETERMINING STORMWATER MANAGEMENT REQUIREMENTS: This stormwater calculation worksheet should be completed first to
classify the proposal as “small,” “medium,” or “large.” The size determines whether a Stormwater Site Plan is re quired in
conjunction with a stand-alone stormwater management permit application, building permit application, or other land use approval
application that involves stormwater review. The basic information will also be helpful for completing a Stormwater Site Plan, if
required.
Land-disturbing activity is any activity that results in movement of earth, or a change in the existing soil cover (both vegetative and
non-vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to clearing, grading, filling,
excavation, and compaction associated with stabilization of structures and road construction.
Native vegetation is vegetation comprised of plant species, other than noxious weeds, which reasonably could have been expected
to naturally occur on the site. Examples include species such as Douglas fir, western hemlock, western red cedar, alder, big -leaf
maple, and vine maple; shrubs such as willow, elderberry, salmonberry, and salal; herbaceous plants such as sword fern, foam
flower, and fireweed.

CONSTRUCTION STORMWATER POLLUTION PREVENTION
Best Management Practices (BMPs) Fact Sheet
For “small” projects (as determined through the Stormwater Calculation Worksheet), submit Worksheet
“S” Small Project Certification. Additionally, the applicant shall consider the twelve Construction
Stormwater Pollution Prevention elements and implement applicable BMPs. A set of useful BMPs for
typical rural residential construction is attached. There is no additional submittal required as part of the
permit application.
For “medium” and “large” projects, applicants must submit a Construction Stormwater Pollution
Prevention Plan (SWPPP) and a Stormwater Site Plan (applicants may use Worksheet B1 or equivalent).
The following twelve elements must be considered for Construction Stormwater Pollution Prevention
before and during the construction phase of the project:
1.Mark Clearing Limits 7.Protect Drain Inlets
2.Establish Construction Access 8.Stabilize Channels and Outlets
3.Control Flow Rates 9.Control Pollutants
4.Install Sediment Controls 10.Control De-Watering
5.Stabilize Soils 11.Maintain Best Management Practices
6.Protect Slopes 12.Manage The Project
Each of the twelve elements is described in more detail below:
1.Mark Clearing Limits
By minimizing the limits of clearing on the site, a builder can minimize stormwater runoff and provide
effective control of pollution.
2.Establish Construction Access
Much of the sediment that leaves a construction site does so on the wheels of delivery and construction
vehicles that drive off a project site. Construction access must be limited to a single location and a
properly constructed Stabilized Construction Entrance (BMP C105) should be included on the site.
3.Control Flow Rates
Stormwater that leaves a project site unimpeded may exceed the capacity of the existing stormwater
control facilities downstream and may contain sediment that may be deposited as the velocity of the
runoff decreases. Stormwater protection on a construction site should include measures to control the
flow rate of runoff from the site. This can be done by installing a Sediment Trap (BMP C240) or other
measure that will impede the flow of water off a construction site.
4.Install Sediment Controls
In addition to limiting the rate of stormwater flow off a construction site, measures should be put in place
to treat the runoff and remove sediment. Limiting of the cleared area (Element 1) will assist in this effort,
but there will be exposed soils that may move with the runoff. Suggested BMPs for controlling sediment
include Straw Wattles (BMPC235), Brush Barrier (BMP C231), Gravel Filter Berm (BMP C232), and Silt
Fence (BMP C233). Installation of a Sediment Trap (Element 3) is an additional sediment control feature.
Log Item 36
Page 55 of 218
construction Pollution Prevention Page 2 of 3 5/31/2019
5.Stabilize Soils
An additional measure that can minimize sediment transport in runoff is to stabilize soils on the site with
mulch or some other covering. This will limit the amount of soil that is exposed to rainfall, thus limiting the
sediment that could potentially leave the site. BMPs that could be used for this include Mulching (BMP
C121), Nets and Blankets (BMP C122), and Plastic Covering (BMP C123). During periods of dry weather
dust can become a problem and sediment could be transported from the site in high winds. BMP C140
Dust Control should be followed to limit loss of soils in windy conditions.
6.Protect Slopes
If the cleared area includes slopes of 3:1 (Horizontal: Vertical) or steeper, the slopes should be protected
to limit runoff. If the slopes are not protected, rills and gullies may form, transporting sediment to the
lower elevations and potentially off the construction site. The slopes sh ould be graded to minimize
erosion and runoff at the downstream end of the slopes, and runoff should be collected and treated. The
following BMPs could be used Surface Roughening (BMP C130), Interceptor Dike and Swale (BMP
C200), and Pipe Slope Drains (BMP C204).
7.Protect Drain Inlets
Runoff from urban construction sites often discharges into existing stormwater collection systems. Water
enters the collection system through drain inlets. If there are drain inlets downstream of a construction
site, they should be protected using BMP C220 Storm Drain Inlet Protection.
8.Stabilize Channels and Outlets
Any temporary on-site channels or ditches that are used to control runoff should be stabilized to prevent
erosion in the channel. BMP C202 Channel Lining and BMP C209 Outlet Protection should be used.
9.Control Pollutants
The best way to control pollution is to limit the source of pollution. Construction debris should be
maintained in a safe location. Vehicle maintenance on the construction site should be minimized and any
spill should be promptly cleaned up. Concrete spillage should be kept to a minimum and cleaning of the
concrete trucks after they have unloaded should be done in an area that will not drain off site (see BMP
C151 Concrete Handling).
10.Control Dewatering
In some cases, excavation for the foundation or below ground structures will encounter ground water.
This water must be removed (dewatered) from the excavation. Discharge of this ground water must be
treated in a manner that will not cause damage downstream due to flow rates or added pollution. There
are no specific BMP identified for this activity, but the water should be handled with care to assure that
soils or other pollutants are not added to this flow.
11.Maintain BMPs
Installation of the appropriate BMPs is not adequate to completely control stormwater runoff. The BMPs
that have been installed on the project must be inspected and maintained during the duration of the
construction project. In addition, the temporary controls that were installed for construction should be
removed within 30 days of completion of the work. Typically, once construction has been completed, the
temporary facilities are not maintained, and by removing the facilities, it will ensure that these won’t f ail
and discharge water or sediment that had been previously trapped or contained.
12.Manage the Project
Management of a project has four aspects:
1.Phasing construction to prevent transportation of runoff and sediment,
2.Limiting the work during seasons where large amounts of rainfall could be anticipated,
3.Coordination with Utilities and other Contractors, and
4.Inspection and Monitoring.
All of these for aspects are important and must be followed to ensure a project that will have minimal
impact on the environment. Volume II of the Manual contains additional BMPs that could be used on-site.
The applicant is encouraged to review the Manual to see if other BMPs may be applicable to, or more
useful on, a particular site.

A survey was conducted on 8/20/13 to record habitat conditions at the site of the proposed project. Substrate
and other features identified were as follows: sand, pea gravel, cobble, barnacles, mud, scattered Anthlopeura
elegantissima, and patchy sand dollars. The microalgae consisted of Ulva, native eelgrass (Zostera marina), and
non-native dwarf eelgrass (Zostera japonica). See the Biological Evaluation for additional detail.
The site has also been surveyed several times to map the extent of the Z. marina bed. Confluence
Environmental conducted an eelgrass survey on July 20, 2016 to reconfirm the extent of the eelgrass bed
previously surveyed In September 2015. Both Z. marina and Z. japonica are present within the project site. Z.
marina is abundant at subtidal and lower intertidal elevations, while Z. japonica is very sparsely distributed at
higher intertidal elevations. A bed of dense, robust Z. marina is located seaward of the extreme low tide
elevation (approximately -2 ft. MLLW). Landward of this dense bed edge the beach is substantially composed of
bare sand with occasional patches of sparse Z. japonica. No Z. marina is present landward of approximately -2
ft. MLLW. Planting of geoducks is planned between approximately +2 MLLW and a 5-meter (16.4 ft.) buffer of
the dense Z. marina bed edge. The eelgrass survey performed by Confluence is attached to the enclosed
Specific Project Information Form ("SPIF").
Because more than one year has lapsed since the previous survey was completed, the Washington
State Department of Ecology and Jefferson County requested that the bed edge be re-verified to ensure the
proposed project will be sited at least 16 feet from native eelgrass so as to reduce the potential for negative
impacts to protected resources. A biologist knowledgeable in Pacific Northwest seagrass identification and
survey methods visited the Smersh parcel during low tide on June 28th, 2018 between 11:00 am and 1:00 pm. At
that time, water elevations ranged from -0.3 feet to -1.6 feet relative to MLLW. The surveyor crisscrossed the
entire parcel while scanning the substrate to the left and right to locate and identify any submerged aquatic
vegetation, with a specific focus on locating native eelgrass. As with previous surveys, very small, sparse
patches of non-native Japanese eelgrass (Zostera japonica) were found widely distributed between
approximately +2 feet and -1 foot MLLW. No native eelgrass was found above -1 foot MLLW. A dense bed of
native eelgrass with a patchy margin was observed below approximately -1 to -2 feet MLLW. The location of the
landward edge of the native eelgrass bed was accurately recorded using a differential GPS with sub-meter
accuracy. The 2018 bed edge closely matches the 2016 bed edge in some areas but the patchy margin has
receded waterward in many areas Nowhere has the bed expanded landward of the 2016 margin. Thus, the
geoduck planting area proposed in 2016, and permitted by the Corps in 2017, will not be altered in the
application for a Jefferson County conditional use permit. (See attached Proposed Smersh Geoduck Farm:
2018 Zostera marina bed edge re-verification, dated July 9, 2018.)

BDN proposes to cultivate Pacific geoduck (Panopea generosa). The planting area will consist of
approximately 5.15 acres, generally between approximately +2 ft. MLLW and a 5-meter (16.4 ft.)
buffer of the native eelgrass (Zostera marina) bed edge, located between approximately -1MLLW
and -2 MLLW.
To protect geoduck seed from predators, PVC tubes 4” in diameter by 10" long will be manually
placed in the substrate at low tide, while the tidelands are exposed, before any geoduck seed is
planted. The tubes are inserted into the substrate such that at least half of the tube is below the
substrate and the remainder is above it. A low pressure water hose may be used to loosen the
substrate sufficiently to properly insert the tubes. Tubes will be spaced at approximately one tube
per square foot in the planting area. Only 3”-5" of the tubes will be exposed above the substrate.
Tubes will be labeled with contact information for BDN. 12-25 workers will work to insert these PVC
tubes during each approximately 5-hour shift. This will allow for approximately 6,000-10,000 tubes
to be placed per day.
Geoduck seed will then be obtained from a certified hatchery and typically planted in the installed
PVC tubes when 4-5 mm in size. The juvenile geoducks will be placed in the installed tubes by
divers during times when the tubes are submerged. No water jets will be used during placement of
the seed in the PVC tubes. The PVC tubes will be covered with a mesh cap and secured with UV-
resistant rubber bands after the seed has been planted. Planting will begin in spring and continue
through fall. Planting activities will occur once per year, typically in June or July, over a period of 20-
25 days.
No netting will be installed over the tubes, and no rebar or other materials will be used in connection
with the planting maintenance or harvest activities. The installed PVC tubes are very resistant to
dislocation during severe weather, or from geoduck movement and activity, so no securing nets are
necessary. Any dislodged tubes do not float, and thus tend to remain on or near the tract even if
dislodged, where they can be retrieved by regular beach inspections. No fill materials or other
nursery/grow-out structures will be installed on the site. The project may result in the removal of
non-native Japanese dwarf eelgrass (Z. japonica) located in the proposed planted area.
Site inspections will be made weekly, or more frequently if needed due to adverse weather or citizen
complaints, to ensure that PVC tubes have not become dislodged. BDN has implemented an
aquaculture gear maintenance plan, appended as Attachment I-2, to address potential gear
escapement and to facilitate quick recovery of any gear displaced by storm activity. Site inspections
will be generally conducted by 2-4 BDN employees walking the tidelands and surrounding areas at
low tide. Site maintenance will also include monitoring and relocation of built-up drift microalgae
(e.g. Ulva). If low tide periods occur at night, these workers may use individual LED headlamps for
such inspection and maintenance work. If any maintenance work is required, this will be performed
by as many as four people, but should typically require no more than 1 hour for each such
maintenance event. No vessel operations will take place at night.
Two years after planting, when the geoducks have reached a depth sufficient to avoid predators,
beach workers will remove the tubes by hand at low tide. Consistent with Corps requirements, if any
herring spawn is found on the PVC tubes, they will not be removed until the eggs have hatched.
The tubes will be placed in large bags and removed for reuse or proper upland disposal.
Usually, harvesting will begin between five and six years after planting; the exact timing of
harvesting will depend on a variety of environmental and economic factors. The total harvest
window is expected to be 1-2 years. The majority of harvesting will be conducted at high tides by
divers using surface-supplied air. A small amount of beach harvesting will be conducted during the
"cleanup" harvest phase at the end of the harvesting period when there are fewer geoducks

remaining on the beach. Both dive harvests and beach harvests use the same extraction
equipment. A diesel or gasoline engine located on the work skiff is used to power a water jet nozzle
that loosens the substrate around each geoduck. The engine will have a muffler to minimize noise
impacts. The water intake hose will include a 2.36 mm wire mesh screen covering the intake to
prevent fish entrainment in the low-pressure pump. The water jet nozzle is at the end of an
approximately 150' long, 1.5" delivery hose. The nozzle is approximately 27" long and may supply
up to 20-30 gallons of water per minute at 40 psi
After geoducks are removed from the substrate as described above, they will be stored in crates
located on the work skiff prior to transport off-site. During both dive and beach harvesting, the work
skiff will not be anchored in any native eelgrass beds. Dive harvests will be conducted during
daylight hours. Divers work within a 150' radius of the work skiff at depths of 5' to 20' using surface
supplied air. The vessel engine will be turned off while divers are working for diver safety. When
beach harvesting, the skiff is regularly moved so that it always remains near the water's edge.
Water hoses are then run from the skiff to the beach. Dive harvests will employ 1 diver and 2
support workers in the skiff. Dive harvesting will usually last for 3-to 6 hours each harvest day.
Beach harvests will employ 2 workers on the beach and 2 support workers on the skiff.
Harvesting activities at this location will occur only during daylight hours, over a period of about 5
hours per day, averaging 3-4 harvest days per week during the one to two year harvest period.
BDN will comply with Corps' conditions associated with herring, surf smelt, and sand lance
spawning.

Re: Addendum to Biological Evaluation of BDN LLC Smersh Geoduck Aquaculture Project
(NWS-2013-1268)
This document is intended to amend the Biological Evaluation (“BE”) provided by Marine Surveys and
Assessments, Inc., dated October 28, 2013. At the request of the Corps, Confluence has performed
additional eelgrass surveys to confirm the location of native eelgrass (Zostera marina) at the
Smersh/Nelson site. This Addendum updates the BE through updating the location of native eelgrass
on the site, revising the location of proposed geoduck planting consistent with the location of the
eelgrass bed and Corps’ eelgrass buffer requirements, and provides additional analysis regarding the
potential for indirect effects to threatened or endangered species listed under the Endangered Species
Act (ESA) due to potential impacts to eelgrass from geoduck culture and harvest activities. This
Addendum is intended to supplement the original analysis in the BE and any descriptions or analysis
not modified herein should be considered to still be valid and accurate.
A. REVISIONS TO PROJECT DESCRIPTION
Based upon the updated eelgrass survey, BDN has revised its proposed planted area as shown on Figure
1. The revised planted area will consist of approximately 5.15 acres, generally between approximately
+2 ft. MLLW and a 5-meter (16.4-ft) buffer of the dense Z. marina bed edge, located between
approximately -1 MLLW and -2 MLLW.1,2 There are also a couple of minor modifications to BDN’s
proposed operations as compared to what is described in the BE. BDN employees working at the
Smersh parcel will now park primarily on a private upland parcel (Assessor’s No.821344064), or on
property owned by James Smersh located across the street from the project site as a staging area.
Further, while BDN may use a skiff in the manner described in Section 4.b.(1) of the BE (pg. 6), most site
inspections will be conducted by walking the beds at low tide.

not anticipate using area nets.

B. ADDITIONAL EELGRASS SURVEYS
Confluence performed several additional eelgrass surveys on the Smersh parcel. On September 4, 2015,
Confluence used a towed video system with integrated Global Positioning System (GPS) to collect
information about native eelgrass presence/absence. The towed video data were collected in transects
running perpendicular to the beach and spaced about every 45 feet. In addition, a transect that ran
parallel to the shoreline was collected along the anticipated eelgrass bed edge and landward of the
edge. The video system electronically recorded latitude and longitude to aid in the mapping of native
eelgrass locations. A differential GPS (dGPS) with sub-meter accuracy was used to collect positions at
one second intervals during the towed video surveys. To aid mapping, a proprietary program created by
Confluence was used when reviewing the video to characterize the presence/absence of eelgrass. The
entirety of the field-collected video data was reviewed in the office on a high definition monitor to
ensure that habitat variables were accurately characterized. Tabular data describing the vegetative
cover, substrate material, relief, and complexity were then joined, using a time stamp, to the dGPS
positions thereby allowing the high quality characterization of video in the office to be linked to the
dGPS positions and video data collected in the field.
During the September 29, 2015 survey, the edge of native eelgrass was confirmed using snorkel-based
surveys and a dGPS unit at the Smersh site. Two biologists snorkeled the landward native eelgrass
boundary using a floating dGPS unit to precisely collect location data. The biologists divided the area
into two eelgrass zones: patchy vs. continuous. These zones were mapped according to the following
criteria: (1) Patchy = individual shoots or small patches of native eelgrass (typical of shoots migrating
from the main eelgrass bed), (2) Continuous = the main native eelgrass bed with few locations where
eelgrass was absent (typical of a fringe eelgrass bed). The landward edge of the patchy eelgrass zone
was considered to be the upper (or landward) extent of native eelgrass habitat. Underwater video,
using a GoPro HERO4 camera, was collected during the snorkel-based surveys. The results from the
September 2015 eelgrass surveys are depicted in Figure 2.
Pursuant to the Corps’ request, Confluence conducted another eelgrass survey on the Smersh parcel on
July 20, 2016 to reconfirm the extent of the eelgrass bed surveyed in 2015. A surveyor walked the Z.
marina bed edge, recording the location using a GPS unit with decimeter accuracy. The location of the
marina bed edge was substantially similar to that mapped by Confluence in 2015 and is depicted in
Figure 1.
C. ADDITIONAL ANALYSIS REGARDING EFFECTS TO EELGRASS
Effects to eelgrass have the potential to result in changes to ecosystem functions provided by eelgrass
beds at the Smersh/Nelson site and, thereby, to ESA-listed species that may benefit from those
services.
1. Location of Eelgrass Beds
Log Item 36
Page 124 of 218
www.confenv.com page 3 of 6
Both native eelgrass (Z. marina) and non-native dwarf eelgrass (Zostera japonica) are present at the
proposed Smersh/Nelson geoduck culture site. Z. marina is abundant at subtidal and lower intertidal
elevations, while Z. japonica is very sparsely distributed at higher intertidal elevations. A bed of dense,
robust Z. marina is located seaward of the extreme low tide elevation (approximately -2 ft. mean lower
low water [MLLW]) (Figure 1). Landward of this dense bed edge the beach is substantially composed of
bare sand with occasional patches of sparse Z. japonica. No Z. marina is present landward of
approximately -2’ MLLW. Planting of geoducks is planned between approximately +2 ft. MLLW and a 5-
meter (16.4-ft) buffer of the dense Z. marina bed edge (Figure 1).
2. Effects to Native Eelgrass from Planting and Maintenance Activities
As mentioned above, the project will incorporate a 5-meter buffer from the identified Z. marina
eelgrass bed, consistent with the Corps’ conservation measure included in the Programmatic Biological
Assessment concerning Shellfish Activities in Washington State Inland Marine Waters (“PBA”). The
Biological Opinions submitted by the National Marine Fisheries Service (“NMFS”) and U.S. Fish &
Wildlife Service both confirm that the buffer will adequately protect eelgrass for new shellfish farms.
For example, NMFS found that new farms “will be required to follow the 16-foot buffer requirements
from native eelgrass, this is not expected to diminish eelgrass density or function of existing eelgrass.”
NMFS, Endangered Species Act (ESA) Section 7(a)(2) Biological Programmatic Opinion and Magnuson-
Stevens Fishery Conservation and Management Act Essential Fish Habitat Consultation: Washington
State Commercial Shellfish Aquaculture and Restoration Programmatic (2016), at pg. 72.
3. Impacts to Non-Native Eelgrass (Z. japonica)
The project may result in the removal of Z. japonica located in the planted area or adverse effects to Z.
japonica from project operations. However, Z. japonica is not a threatened or protected species. To the
contrary, the Washington State Noxious Weed Control Board (NWCB) has classified Z. japonica as a
Class C noxious weed (WAC 16-750-015). Aquatic plants on the noxious weed list are considered “to be
highly destructive, competitive, or difficult to control . . .” (WAC 16-750-001). In adopting the listing,
the NWCB justified the regulation partially based on concerns that Z. japonica can increase the
deposition of silt and detritus. Protecting Z. japonica would be contrary to the State’s designation of the
plant as a Class C noxious weed. Therefore, impacts to Z. japonica existing on the site are considered to
be a less than significant impact.3
3 This amends statements made in the original BE that “Z. japonica will not be removed from the site during
planting. Instead, planting will occur through these patches” (BE, pg. 5) and “Still, any activities that reduce harm to
Z. japonica, such as planting around the patches, would maintain additional valuable habitat at this site” (BE, pg.
15). While the initial BE notes that Z. japonica creates three-dimensional habitat and complexity as compared to
mudflats (pg. 15), as noted above, geoduck aquaculture provides similar three-dimensional complexity through the
introduction of tubes. Further, BDN’s operations west of the project site have documented that BDN’s proposed
geoduck aquaculture can coexist with Z. japonica.

1.0 INTRODUCTION
BDN, Inc. has leased parcel 721031007 (Smersh parcel) on Shine Road, west of the Hood Canal
Bridge, and is proposing to operate a geoduck farm at the site (Figure 1). A conditional use
permit is required by Jefferson County and, as part of the permit application, a cumulative
impacts assessment has been requested by the County pursuant to Jefferson County Code (JCC)
18.25.440 and JCC 18.25.590.
This report provides an assessment of cumulative impacts that may result from the proposed
project. Cumulative environmental effects can be defined as environmental effects caused by
the combined results of past, current, and future activities. This assessment incorporates the
following factors in an assessment and summation of potential cumulative impacts: current
ecological functions, human factors influencing shoreline processes, foreseeable future shoreline
development, beneficial effects of regulatory programs, and conservation measures.
Figure 1. Project area and vicinity.
2.0 PROJECT DESCRIPTION
BDN, Inc proposes to plant up to 5.15 acres of geoducks at the site between +2 feet and
approximately ‐2 feet relative to mean lower low water (MLLW). The lower boundary of
planting will be determined based on the location of the eelgrass bed below approximately ‐2
feet MLLW (Confluence 2016, 2018a).

To protect geoduck seed from predators, PVC tubes 4” in diameter by 10” long would be placed
into the sandy substrate at low tide, while the tidelands are exposed, before any geoduck seed
is planted. Tubes would be placed at an approximate density of 1 tube per square foot with 3”
to 5” of the tube exposed above the substrate. . A low pressure water hose may be used to
loosen the substrate sufficiently to properly insert the PVC tubes. Tubes will be labeled with
contact information for BDN. 12‐25 workers will work to insert these tubes during each
approximately 5‐hour shift. This will allow for approximately 6,000‐10,000 tubes to be placed
per day.
Geoduck seed will then be obtained from a certified hatchery and typically planted in the
installed PVC tubes when 4‐5 mm in size. The juvenile geoducks will be placed in the installed
tubes by divers during times when the tubes are submerged. No water jets will be used during
placement of the seed in the PVC tubes. The tubes will be clipped shut at the top by the divers,
using plastic clips, after the seed has been planted. Planting will begin in spring and continue
through fall. Planting activities will occur once per year, typically in June or July, over a period
of 20‐25 days.
No netting will be installed over the tubes, and no rebar or other materials will be used in
connection with the planting maintenance or harvest activities. No fill materials or other
nursery/grow‐out structures will be installed on the site.
There will be no removal of native materials from the site during site preparation. Excessive
amounts of macroalgae (e.g. Ulva) may be hand‐raked away from the planting area but will be
left on the site. Successive tides will redistribute algae across the site.
Weekly site inspections will be made to ensure that PVC tubes have not become dislodged.
BDN has implemented an aquaculture gear maintenance plan, appended as Attachment K, to
address potential gear escapement and to facilitate quick recovery of any gear displaced by
storm activity. Site inspections will be generally conducted by 2‐4 BDN employees walking the
tidelands and surrounding areas at low tide. Site maintenance will also include monitoring and
relocation of built‐up drift microalgae (e.g. Ulva).
Two years after planting, when the geoducks have reached a depth sufficient to avoid
predators, beach workers will remove the tubes by hand at low tide. Consistent with Corps
requirements, if any herring spawn is found on the tubes, they will not be removed until the
eggs have hatched. The PVC tubes will be placed in large bags and removed for reuse or proper
upland disposal. When needed, lighting on the beach will be limited to individual LED
headlamps. Standard navigational lighting will be used on vessels.
Usually, harvesting will begin between five and six years after planting; the exact timing of
harvesting will depend on a variety of environmental and economic factors. The total harvest
window is expected to be 1‐2 years. The majority of harvesting will be conducted at high tides
Log Item 36

June 2018 Page 3
by divers using surface‐supplied air. A small amount of beach harvesting will be conducted
during the "cleanup" harvest phase at the end of the harvesting period when there are fewer
geoducks remaining on the beach. Both dive harvests and beach harvests use the same
extraction equipment. A diesel or gasoline engine located on the work skiff is used to power a
water jet nozzle that loosens the substrate around each geoduck. The engine will have a muffler
to minimize noise impacts. The water intake hose will include a 2.36 mm wire mesh screen
covering the intake to prevent fish entrainment in the low‐pressure pump. The water jet nozzle
is at the end of an approximately 150' long, 1.5" delivery hose. The nozzle is approximately 27"
long and may supply up to 20‐30 gallons of water per minute at 40 psi.
After geoducks are removed from the substrate as described above, they will be stored in crates
located on the work skiff prior to transport off‐site. During both dive and beach harvesting, the
work skiff will not be anchored in any native eelgrass beds. Dive harvests will be conducted
during daylight hours. Divers work within a 150' radius of the work skiff at depths of 5' to 20'
using surface supplied air. The vessel engine will be turned off while divers are working for
diver safety. When beach harvesting, the skiff is regularly moved so that it always remains near
the water's edge. Water hoses are then run from the skiff to the beach. Dive harvests will
employ 1 diver and 2 support workers in the skiff. Dive harvesting will usually last for 3‐to 6
hours each harvest day. Beach harvests will employ 2 workers on the beach and 2 support
workers on the skiff.
Harvesting activities at this location will occur only during daylight hours, over a period of
about 5 hours per day, averaging 3‐4 harvest days per week during the one to two year harvest
period. BDN will comply with Corps' conditions associated with herring, surf smelt, and sand
lance spawning.
3.0 EFFECTS ANALYSIS
Potential effects to fish and wildlife habitat, boat navigation, aesthetics, and public access/use
are considered in this assessment. Biological impacts and visual impacts have been assessed in
detail in separate reports (Confluence 2018b, Confluence 2018c). Summaries of the findings of
those assessments are included below in addition to evaluations of effects to boat navigation
and public access.
3.1 Biological Impacts
Biological impacts are discussed below as a function of potential effects to water quality (i.e.
filtration by shellfish, turbidity during harvest) and physical habitat functions (i.e. sediment
quality, sediment supply and delivery, submerged aquatic vegetation). Additional detail on
each of these elements is provided in Confluence 2018b.
Log Item 36
Page 134 of 218
BDN Inc. - SMERSH FARM CUMULATIVE IMPACTS REPORT
June 2018 Page 4
3.1.1 Water Quality
Potential effects to water quality and fish and wildlife species or their habitat are different
during the growing and harvest phases of geoduck aquaculture. During the growth phase,
geoducks filter phytoplankton and other particles from the water column. During harvest,
sediment is re‐suspended into the water column. These two aspects are addressed in further
detail below.
3.1.1.1 Filtration
The depth at which photosynthetic submerged aquatic vegetation (SAV) can grow is limited by
the depth at which light penetrates through the water column. Shellfish aquaculture can result
in a beneficial reduction in turbidity, and increase in light penetration, due to removal of
phytoplankton and particulate organic matter through filtration. Improvements to water clarity
and light penetration can improve habitat conditions through the growth of SAV.
Shellfish aquaculture or the presence of a naturally dense bivalve community may provide
some control of human nutrient loading to water bodies. Bivalves remove phytoplankton and
suspended sediment from the water column through filtration, which can have a net benefit to
water quality. When shellfish are harvested, sequestered nutrients are permanently removed
from the system which benefits areas with high nutrient loading, such as Hood Canal.
Shellfish aquaculture infrastructure also provide microhabitats for communities of nitrifying
microbes. Through filtration, sequestration, and hosting of nitrifying microbes, commercial
shellfish aquaculture can be considered a net benefit to water quality ecosystem functions.
3.1.1.2 Turbidity During Harvest
Geoducks can be harvested when the tide is out or by divers when the tide is in; both methods
use a water jet to loosen the sediment around the geoduck which causes a temporary increase in
suspended sediment and turbidity. A geoduck harvest event is limited geographically and
temporally compared to natural storm events which increase suspended sediment and turbidity
to comparable levels.
Exposure to high levels of suspended sediment can stress fish and result in reduced survival
and growth but studies have shown that fish are likely to avoid localized, elevated turbidity
events such as a geoduck harvest.
Both the timing and intensity of potential harvest impacts are below the natural disturbance
regime of typical Puget Sound storm events (VanBlaricom et al. 2015). Experimental results
show that levels of total suspended sediment associated with geoduck harvest are low, with the
majority of sediment deposited within 3 feet of the harvest hole (Short and Walton 1992).
Additionally, mobile species are able to avoid the area during harvest activity. Harvest will
happen only periodically (e.g. 5‐7 years after geoducks have been planted). Because turbidity

Page 135 of 218
BDN Inc. - SMERSH FARM CUMULATIVE IMPACTS REPORT
June 2018 Page 5
impacts during harvest are anticipated to be similar to, or less than, natural storm events,
harvest is not anticipated to result in negative impacts to ecological functions.
3.1.2 Habitat Functions
In‐water projects may have the potential to alter sediment character and quality, sediment
supply and delivery, or distribution of submerged aquatic vegetation. Changes to these
elements could result in either negative or beneficial alteration of habitat in the vicinity of the
project. The potential effects to each of these elements from geoduck culture and harvest is
discussed further below.
3.1.2.1 Sediment Character/Quality
Sediment along the north shore of Squamish Harbor is primarily sandy in the lower elevations
with gravel and cobble on the upper intertidal beach. No sediment contaminants are known in
the proposed project area and the surrounding land use is low density residential, so industrial
sediment contaminants are not likely to be found in the area. The proposed project will not be
using any chemicals that may cause sediment contamination. The proposed project would not
change existing sediment character or quality.
3.1.2.2 Sediment Supply and Delivery
The sandy beach on the north shore of Squamish Harbor slopes gradually and is exposed to
wind‐generated waves from the south, where winter storms typically come from in Puget
Sound. East of the project area there is a high, eroding bluff that supplies sediment to the beach.
Net shore‐drift of sediment is to the west, from the eroding bluff toward the proposed project
site (Ecology 2019). Shoreline armoring is prevalent along the north shore of Squamish Harbor,
which may generally limit sediment supply in the area (ESA Adolphson et al. 2008).
The two types of potential disturbances associated with geoduck aquaculture that could affect
sediment supply and delivery include the use of tubes and netting that slow the transport of
sediments, and sediment re‐suspension due to harvest activities.
A small accumulation of sediment may collect in the proposed geoduck tubes and is expected to
rapidly redistribute through wave and current action after one or two tidal cycles following the
removal of tubes (Short and Walton 1992).
During a geoduck harvest, the overlying sediments are loosened around the clam by a low‐
pressure water hose. Although this activity results in minor, localized changes in elevation and
sediment grain size, both quickly return to baseline conditions within one month after harvest
(Short and Walton 1992).
In summary, geoduck harvest and the presence of culture tubes do not lead to significant
impacts to sediment transport or bathymetry. Minor changes in elevation may persist for up to
Log Item 36

BDN Inc. - SMERSH FARM CUMULATIVE IMPACTS REPORT
June 2018 Page 6
1 month, but these effects are insignificant compared to the natural sediment dynamics along
the shoreline associated with the project area.
3.1.2.3 Submerged Aquatic Vegetation
A dense bed of eelgrass (Zostera marina) extends from approximately ‐3 ft MLLW, waterward of
the project area to an unknown depth. A narrow band of sparse, patchy eelgrass is landward of
the dense bed between approximately ‐2 and ‐3 feet MLLW. Several sparse patches of non‐
native dwarf eelgrass (Zostera japonica) were observed distributed in the proposed project area.
Throughout the Puget Sound, a 16‐foot protective buffer around native eelgrass beds is used to
minimize the impact of new shellfish aquaculture activities (Corps 2015). The width of this
buffer is based on field experiments and observations that suggest the maximum distance of
seed dispersal is 5 meters (16.4 ft) and the maximum potential annual migration zone is ‐5m to
+4m (DNR unpublished data, Ruckelshaus 1996). By maintaining a protective buffer around
eelgrass beds of 16 ft, it is presumed that geoduck farming activities would not intersect
eelgrass beds and would have no impact on the growth and survival of nearby native eelgrass.
At present, eelgrass occurs at least 16 ft from the proposed geoduck planting area based on
multiple bed delineation surveys (Confluence 2016, 2018a). While eelgrass beds are known to
expand, contract, and shift on an annual basis, it is not likely that eelgrass would move into the
proposed culture area. The consistent location of the eelgrass bed edge mapped in two surveys
two years apart indicates the stability of this landward bed edge, with little change to the extent
of dense eelgrass found below ‐2 ft MLLW (Confluence 2016, 2018a).
The location of the landward edge of eelgrass beds is largely determined by physical
characteristics associated with the intertidal zone; primarily desiccation stress (Koch 2001, Boese
et al. 2005). Eelgrass higher in the intertidal zone is exposed to air more frequently and for
longer durations with each tidal cycle, resulting in increased desiccation damage (Boese et al.
2005). Zostera species are relatively tolerant of desiccation, but patches of Z. marina in the higher
intertidal zone are usually associated with drainage channels or depressions (Thom 1990).
Z. japonica is more tolerant of desiccation and therefore occurs at higher tidal elevations than the
native eelgrass (Leuschner et al. 1998).
Log Item 36
Page 137 of 218
BDN Inc. - SMERSH FARM CUMULATIVE IMPACTS REPORT
June 2018 Page 7
Figure 2. Eelgrass delineation (2016, 2018) results.
Waves can also limit the expansion of eelgrass beds, as seedlings and new shoots are not
tolerant of high current velocities and wave action (Koch 2001). The Smersh parcel faces south
into Hood Canal and is positioned such that waves originating in the southern portions of Hood
Canal have approximately 12 miles of fetch in which to gain amplitude. Prevailing winds over
the Puget Sound are south or southwest during the winter, when the strongest storms move in
off the Pacific Ocean (Finlayson 2006). Southerly winter winds and long fetch distances create
the potential for significant wave action at the proposed farm site. During low tide events at the
project location, the beach is exposed to waves and resulting scour/erosion, as well as
desiccation; both of which increase stress on the plants and limit its landward expansion. Thus,
the edge of the native eelgrass bed is unlikely to move to areas landward of its current extent at
approximately ‐2 ft MLLW.
Macroalgae beds are not found in or near the project area. Green algae (Ulva spp) were present
at a very low density, attached to a small number of hard objects such as derelict clam shells in
the proposed aquaculture area.
Log Item 36
Page 138 of 218
BDN Inc. - SMERSH FARM CUMULATIVE IMPACTS REPORT
June 2018 Page 8
Macroalgae density is anticipated to increase in the project area due to geoduck farming as the
PVC tubes provide solid substrate required by macroalgae for attachment and growth.
Because the project will be located outside of a 16‐foot protective buffer from native eelgrass, no
negative effects are anticipated to occur to eelgrass due to the proposed project and there may
be an ecological lift from the potential increase in other macroalgal species on the tubes .
3.2 Impacts to Navigation
The project parcel is located adjacent to the W.R. Hicks County Park, which includes a small
boat ramp. Thus, there is potential for boat traffic and recreational use of the surrounding
waters by small boats and kayaks. Because geoducks are grown in the sediment and associated
tubes have very low relief (less than 5 inches), boating and kayaking is unlikely to be
significantly affected. Additionally, the intertidal area where the farm is proposed is shallow
and not generally suitable for boating making impacts to boat navigation unlikely. Usual
aquaculture activities (i.e. weekly farm maintenance) will require up to four workers accessing
the intertidal beach during low tide. Because this routine activity does not occur in the water, no
impacts to kayaking are anticipated. Also, while up to two boats may be required to support
harvest events, this level of boat traffic is not expected to significantly affect kayaking or other
recreational boating activity.
3.3 Impacts to Aesthetics
A visual impacts assessment was completed as part of this project and indicates that visual
impacts due to the project would be very low (Confluence 2018b). The proposed geoduck
planting area covers less than 5 percent of the cone of vision when viewed from nearby
residences. The project is 500 feet wide along the nearly 2‐mile‐long northern shoreline of
Squamish Harbor.
The Smersh site is located on a heavily altered shoreline in a medium‐density, residential
neighborhood. The shoreline has been altered by rip rap hardening, there is a concrete boat
ramp and gravel parking lot on the adjacent public property, riparian trees have been removed
from a number of the adjacent properties to increase private views, and the paved roadway is
adjacent to the shoreline for approximately 1 mile next to the Smersh parcel.
Tides low enough to expose the planting area follow a seasonal pattern in the Puget Sound
region. Larger‐magnitude summer low tides occur during daylight hours, while winter low
tides occur at night. Therefore, geoduck tubes are more visible in summer, and minimal in
winter. Also, geoduck tubes have very low relief and natural macroalgae colonizes equipment
rapidly, quickly resulting in natural color and texture.
Given the site is visible only a small portion of the time, the site is not visible from heavily
traveled routes, the surroundings are heavily altered by local residential development, and the
Log Item 36
Page 139 of 218
BDN Inc. - SMERSH FARM CUMULATIVE IMPACTS REPORT
June 2018 Page 9
geoduck tubes will quickly take on a natural color due to colonization by aquatic flora and
fauna, there would be only very low impacts to aesthetics.
3.4 Impacts to Public Access
Beach walking, clam digging, crabbing, fishing, boating, and kayaking are common recreational
activities near the proposed farm site. The project parcel is located next to a public county park
but is itself located on private tidelands. Thus, there will be no impacts to beach access as part of
this project as the tidelands are not currently accessible by the public. Due to the only slight
emergence of the tubes above the substrate (5 inches), water dependent uses (e.g. boat access,
kayak access) will not be significantly affected.
4.0 CONCLUSION
Based on communication with Jefferson County, no other like actions are present or proposed in
the area that will cumulatively increase impacts to the area (Bausher 2018, Frostholm 2019). As
presented above, the proposed project would have minimal negative impact on the local
shoreline and some beneficial impacts. Past and current use of the area is residential and any
impacts to the shoreline are incorporated into existing background conditions. Thus, the
cumulative impact of the project on the local ecosystem would range from none to minor as
summarized in Table 1.

Turbidity will be temporarily increased during harvest,
but this will not negatively impact habitat because

Sediment character and quality will not change as part
of the proposed project.
Sediment supply and delivery may be temporarily
impacted by accumulating sediment during the
proposed project and releasing sediment during
harvest.
Protective buffers will be maintained around native
eelgrass and macroalgae may be beneficially impacted
during the proposed project by increasing the substrate
where it can establish.

extends only 5 inches above substrate.

Re: BDN Inc. - Proposed Smersh Geoduck Farm: 2018 Zostera marina bed edge re-verification
This memo summarizes the findings of surveys conducted by Confluence Environmental Company
(Confluence) to re‐verify the location of the landward edge of the native eelgrass (Zostera marina)
bed on Jefferson County parcel 721031007 (Smersh parcel). The bed edge was previously surveyed in
2016 by Confluence. Representatives of the U.S. Corps of Engineers (Matthew Bennett, Pamela
Sanguinetti, and Deborah Schaeffer) visited the Smersh parcel on July 21, 2016 to confirm the
findings of the 2016 eelgrass delineation. The Corps was in agreement with the methods and agreed
that the boundaries of the dense and patchy eelgrass beds were appropriately mapped at that time.
Because more than one year has lapsed since the previous survey was completed, the Washington
State Department of Ecology and Jefferson County have requested that the bed edge be re‐verified to
ensure the proposed geoduck aquaculture project will be sighted at least 16 feet from native eelgrass
so as to reduce the potential for negative impacts to protected resources.
A biologist knowledgeable in Pacific Northwest seagrass identification and survey methods visited
the Smersh parcel during low tide on June 28th between 11:00 am and 1:00 pm. During the time of the
survey, water elevations ranged from ‐0.3 feet to ‐1.6 feet relative to mean lower low water (MLLW).
The surveyor crisscrossed the entirety of the parcel while scanning the substrate to the left and right
in an effort to locate and identify any submerged aquatic vegetation at the site, with a specific focus
on locating native eelgrass.
As with previous surveys, very small, sparse patches of non‐native Japanese eelgrass
(Zostera japonica) were found widely distributed between approximately +2 feet and ‐1 foot MLLW.
No native eelgrass was found above ‐1 foot MLLW. A dense bed of native eelgrass with a patchy
margin was observed below approximately ‐1 to ‐2 feet MLLW. The location of the landward edge of
the native eelgrass bed was accurately recorded using a differential GPS with sub‐meter accuracy.
The 2018 bed edge closely matches the 2016 bed edge in some areas but the patchy margin has
receded waterward in many areas (Figure 1). Nowhere has the bed expanded landward of the 2016
margin. Thus, the geoduck planting area proposed in 2016, and permitted by the Corps in 2017, will
not be altered in the application for a Jefferson County conditional use permit.

1.0 INTRODUCTION
BDN, Inc., (BDN) has leased parcel 721031007 (Smersh parcel) on Shine Road, in Squamish Harbor,
west of the Hood Canal Bridge and is proposing to operate a geoduck farm at the site (Figure 1). A
conditional use permit is required by Jefferson County and, as part of the permit application, a
habitat management plan and no net loss report are required (JCC 18.25.440).
The standard of “No Net Loss” of ecological functions was established by Washington State in the
Shoreline Management Act of 1971 and is implemented through a framework outlined in Jefferson
County’s Shoreline Master Program. This document presents an assessment of the proposed
aquaculture activities and demonstrates how geoduck aquaculture at the Smersh parcel will be
managed to achieve no net loss of ecological functions.
2.0 PROJECT DESCRIPTION
The project, if approved with current design, will consist of the following elements as described
below. Potential impacts described herein are based on this current design.
BDN proposes to plant up to 5.15 acres of geoducks at the site between +2 feet and approximately -2
feet relative to mean lower low water (MLLW) (Figure 2). The lower boundary of planting has been
Figure 1. Smersh Parcel and Vicinity

Page 2
determined based on the location of the eelgrass bed below approximately -2 feet MLLW
(Confluence 2016, Confluence 2018).
To protect geoduck seed from predators, PVC tubes 4” in diameter by 10” long would be placed
into the sandy substrate at low tide, while the tidelands are exposed, before any geoduck seed is
planted. Tubes would be placed at an approximate density of 1 tube per square foot with 3” to 5”
of the tube exposed above the substrate. A low pressure water hose may be used to loosen the
substrate sufficiently to properly insert the PVCtubes. Tubes will be labeled with contact
information for BDN. 12-25 workers will work to insert these tubes during each approximately 5-
hour shift. This will allow for approximately 6,000-10,000 tubes to be placed per day.
Geoduck seed will then be obtained from a certified hatchery and planted in the installed PVC
tubes when 4-5 mm in size. The juvenile geoducks will be placed in the installed PVC tubes by
divers during times when the tubes are submerged. No water jets will be used during placement
of the seed in the PVC tubes. The tubes will be clipped shut at the top by the divers, using plastic
clips, after the seed has been planted. Planting will begin in spring and continue through fall.
Planting activities will occur once per year, typically in June or July, over a period of 20-25 days.
No netting will be installed over the tubes, and no rebar or other materials will be used in
connection with the planting, maintenance or harvest activities. No fill materials or other
nursery/grow-out structures will be installed on the site.

2.1 Planting and Grow-Out
Locations for geoduck clam aquaculture do not typically require much, if any, site preparation prior
to planting because they are located in sandflats or mudflats that do not have large substrate
materials. Substrate composition in the proposed culture area is primarily sand.
There will be no removal of native materials from the site during site preparation. Excessive
amounts of macroalgae (i.e., Ulva) will be hand-raked away from the planting area but left on-site.
Successive tides will redistribute algae across the site. Non-native dwarf eelgrass (Zostera japonica),
which is very sparsely distributed throughout the proposed planting area (Confluence 2016,
Confluence 2018), will not be removed during planting. Native eelgrass (Zostera marina) will not be
disturbed and all geoduck planting will occur outside of the 16-foot buffer from eelgrass bed as
delineated by Confluence Environmental Company (Confluence) in July 2016 and reverified in
2017. Site preparation, if any, would occur at the same time as culture tube installation.
Geoduck seed are highly vulnerable to predation because of their small size and the shallow depth
at which they reside in the substrate when small. There will be no active predator removal from the
site. Predator control would be achieved through exclusion by planting geoduck seed into plastic
PVC culture tubes. Two years after planting, when the geoducks have reached a depth sufficient to
avoid predators, beach workers will remove the tubes by hand at low tide. Consistent with Corps
requirements, if any herring spawn is found on the PVC tubes, they will not be removed until the
eggs have hatched. The PVC tubes will be placed in large bags and removed for reuse or proper
upland disposal.
Usually, harvesting will begin between five and six years after planting; the exact timing of
harvesting will depend on a variety of environmental and economic factors. The total harvest
window is expected to be 1-2 years. The majority of harvesting will be conducted at high tides by
divers using surface-supplied air. A small amount of beach harvesting will be conducted during the
"cleanup" harvest phase at the end of the harvesting period when there are fewer geoducks
remaining on the beach. Both dive harvests and beach harvests use the same extraction equipment.
A diesel or gasoline engine located on the work skiff is used to power a water jet nozzle that
loosens the substrate around each geoduck. The engine will have a muffler to minimize noise
impacts. The water intake hose will include a 2.36 mm wire mesh screen covering the intake to
prevent fish entrainment in the low-pressure pump. The water jet nozzle is at the end of an
approximately 150' long, 1.5" delivery hose. The nozzle is approximately 27" long and may supply
up to 20-30 gallons of water per minute at 40 psi.
After geoducks are removed from the substrate as described above, they will be stored in crates
located on the work skiff prior to transport off-site. During both dive and beach harvesting, the
work skiff will not be anchored in any native eelgrass beds. Dive harvests will be conducted during
daylight hours. Divers work within a 150' radius of the work skiff at depths of 5' to 20' using surface
supplied air. The vessel engine will be turned off while divers are working for diver safety. When
beach harvesting, the skiff is regularly moved so that it always remains near the water's edge.
Log Item 36

BDN Habitat Management Plan and No Net Loss Report
Page 4
Water hoses are then run from the skiff to the beach. Dive harvests will employ 1 diver and 2
support workers in the skiff. Dive harvesting will usually last for 3-to 6 hours each harvest day.
Beach harvests will employ 2 workers on the beach and 2 support workers on the skiff.
Harvesting activities at this location will occur only during daylight hours, over a period of about 5
hours per day, averaging 3-4 harvest days per week during the one to two year harvest period.
BDN will comply with Corps' conditions associated with herring, surf smelt, and sand lance
spawning.
Site inspections will be made weekly, or more frequently if needed due to adverse weather or
citizen complaints, to ensure that PVC tubes have not become dislodged by storm activity. Site
inspections will be generally conducted by 2-4 BDN employees walking the tidelands and
surrounding areas at low tide. Site maintenance will also include monitoring and relocation of
built-up drift macroalgae (e.g. Ulva). If low tide periods occur at night, these workers may use
individual LED headlamps for such inspection and maintenance work. If any maintenance work is
required, this will be performed by as many as four people but should typically require no more
than 1 hour for each such maintenance event. No vessel operations will take place at night.
2.2 Maintenance
2.2.1 Site Inspection
Regular site inspections will be made during low tides to ensure that PVC tubes have not become
dislodged and drifted onto the beach. All unnatural debris will be removed from the beach to
prevent it from entering the water. These regular inspections will continue until all tubes have been
removed from the beach. Inspections will typically be made with 2 to 4 workers and staged from
the 24-foot work skiff. Inspections will include monitoring for build-up of drift macroalgae. Ulva
can unexpectedly inundate a given farm, covering tubes entirely and choking out all sea-life below,
including juvenile geoduck clams. Drift algae is typically heaviest in late spring to mid-summer
months. If a given farm area becomes heavily infested with the drift algae, the algae can be picked
up and moved to the top of the farm area where it can be distributed on the upper beach portion
that is not used for farming.
2.2.2 Tube Removal
The tubes will be removed when the geoducks have reached a depth sufficient to avoid predators.
The depth to which the geoducks can burrow is typically substrate driven, and they tend to burrow
more quickly in sandy substrates versus those substrates containing a mixture of shell or gravel. In
sandier substrates, the geoducks may burrow to the desired protective depth of 18 to 24 inches in 18
months, whereas in substrates with more gravel, it may take as much as 24 months to accomplish
this. In either case, tube removal should be completed within 24 months of planting.
All gear installed on a particular beach must be removed during the lowest tides of the year. When
a particular beach is ready for gear removal, workers will come to the beach by boat and remove all
Log Item 36
Page 154 of 218
BDN Habitat Management Plan and No Net Loss Report
Page 5
PVC tubes by hand. Consistent with Corps requirements, prior to removal, PVC tubes will be
inspected for herring spawn. If any herring spawn is found, no tubes will be removed until eggs
have hatched. Workers will remove the PVC tubes by hand and place them in large bags that will
be stored on the work boat until all the gear is removed from the site for reuse or proper upland
disposal at an approved disposal site.
Tube removal will be done from winter to early summer to avoid Ulva buildup, as the weight of
accumulated Ulva can add thousands of pounds to aquaculture equipment. A crew of 10 workers
will be used to remove approximately 5,000 tubes per day.
2.3 Harvesting
Typically, harvesting will begin between five and six years after planting; the exact timing of
harvesting will depend on a variety of environmental and economic factors. The total harvest
window is expected to be 1-2 years. The majority of harvesting will be conducted at high tides by
divers using surface-supplied air. A small amount of beach harvesting will be conducted during the
"cleanup" harvest phase at the end of the harvesting period when there are fewer geoducks
remaining on the beach. Both dive harvests and beach harvests use the same extraction equipment.
A diesel or gasoline engine located on the work skiff is used to power a water jet nozzle that
loosens the substrate around each geoduck. The engine will have a muffler to minimize noise
impacts. The water intake would be fitted with screens that meet National Marine Fisheries Service
(NMFS) screening criteria to prevent fish entrainment in the low-pressure pump. The water jet
nozzle is at the end of an approximately 150' long, 1.5" delivery hose. The nozzle is approximately
27" long and may supply up to 20-30 gallons of water per minute at 40 psi.
Harvesting would be accomplished by 2- to 4-person teams. After geoducks are removed from the
substrate as described above, they will be stored in crates located on the work skiff prior to
transport off-site. During both dive and beach harvesting, the work skiff will not be anchored in
any native eelgrass beds. Dive harvests will be conducted during daylight hours. Divers work
within a 150' radius of the work skiff at depths of 5' to 20' using surface supplied air. The vessel
engine will be turned off while divers are working for diver safety. When beach harvesting, the
skiff is regularly moved so that it always remains near the water's edge. Water hoses are then run
from the skiff to the beach. Dive harvests will typically employ 1 diver and 2 support workers in
the skiff. Dive harvesting will usually last for 3-to 6 hours each harvest day. Beach harvests will
employ 2 workers on the beach and 2 support workers on the skiff.
Harvesting activities at this location will occur only during daylight hours, over a period of about 5
hours per day, averaging 3-4 harvest days per week during the one to two year harvest period.
BDN will comply with Corps' conditions associated with herring, surf smelt, and sand lance
spawning.

2.4 Habitat Management Plan
Avoidance, conservation, and minimization measures that would be adopted at the proposed
geoduck farm are consistent with those outlined in relevant shellfish culture conservation measures
adopted by the U.S. Army Corps of Engineers (Corps) in their programmatic consultation with the
NMFS (2016a) and USFWS (2016) on Nationwide Permit 48 for shellfish farming in the State of
Washington. Avoidance of potential effects, where possible, is the priority. The avoidance,
conservation, and minimization measures at the proposed geoduck farm include the following and
are described in more detail in Sections 2.4.1, 2.4.2, and 2.4.3:
Maintenance, Repair, and Work
Species-Specific Activities
Farm Plan Record-Keeping Log
2.4.1 Maintenance, Repair, and Operation
1. Damage to aquatic vegetation and substrates from boats or barges will be avoided through
the following practices:
Boats and barges shall be moored and operated in deeper water and away from
aquatic vegetation to prevent potential impacts from propeller scour or anchors.
If boats need to come into the project area for personnel or gear access, then vessels
shall not ground in native eelgrass or attached kelp beds.
Groundings will be minimal and temporary and only occur in areas of blank sand
where a boat’s grounding will have no effect on fish and wildlife conservation areas
or intertidal habitat. Vessels would have approximately 20 square feet of ground
contact for up to 6 hours per day during approximately 10 low tide workdays per
year.
Measures shall be implemented to prevent anchors, chains, and ropes from dragging
on the bottom. No vessels will be anchored over native eelgrass beds.
Intertidal areas shall not be used to store materials such as tools, bags, marker stakes,
or PVC tubes. Materials that are not in use or immediately needed shall be removed
to an off-site storage area and the site kept clean of litter.
All excess or unsecured materials and trash shall be removed from the beach prior to
the next incoming tide.
Moving large substrate materials (e.g., logs, rocks) during aquaculture operations
shall be avoided to the extent feasible. Where the relocation of such features is
necessary, they shall be relocated no farther than another section of the nearby beach.
Log Item 36
Page 156 of 218
BDN Habitat Management Plan and No Net Loss Report
Page 7
There shall be no modification of substrate in an effort to improve conditions for
geoduck clam aquaculture.
2. Operators of vehicles or machinery will reduce contamination from vehicles and equipment
through the following practices:
Pump intakes (e.g., geoduck harvest) that use seawater shall be screened in
accordance with NMFS and Washington Department of Fish and Wildlife (WDFW)
criteria to protect fish life.
Unsuitable material (e.g., trash, debris, asphalt, or tires) shall not be discharged or
used as fill (e.g., create berms, or provide nurseries).
All vessels operated within 150 feet of any stream, waterbody, or wetland shall be
inspected daily for fluid leaks before leaving the staging area. Repair any leaks
detected in the staging area before resuming operation.
3. At least once a month and directly following storm events, beaches in the project vicinity
shall be patrolled by crews who will retrieve aquaculture debris (e.g., PVC tubes) that
escape from the project area. Within the project vicinity, locations shall be identified where
debris tends to accumulate due to wave, current, or wind action, and after weather events
these locations shall be patrolled by crews who will remove and dispose of debris
appropriately.
4. The grower shall not use tidelands waterward from the line of mean higher high water
(MHHW) for the storage of aquaculture gear. All aquaculture gear shall be stored and
sorted at an upland facility and transported to the project area at the time of deployment.
5. The grower shall ensure that PVC culture tubes are secured in the substrate to prevent them
from escaping from the project area.
6. Employees shall be trained in meeting environmental objectives.
2.4.2 Species-Specific Activities
1. A Pacific herring spawn survey shall be conducted prior to undertaking the activities listed
below if any of these activities occur outside the Tidal Reference Area 13 in-water work
window, which is April 15 through January 14 (Washington Administrative Code [WAC]
220-110-271). Activities requiring a spawn survey include: (1) PVC culture tube placement,
(2) geoduck harvesting, and (4) culture tube removal. Vegetation, substrate, and aquaculture
equipment (e.g., P tubes) shall be inspected for Pacific herring spawn. If herring spawn is

3.0 EFFECTS ANALYSIS
The “no net loss” standard contained in WAC 173-26-186 requires that the impacts of shoreline use
and/or development (e.g., geoduck aquaculture) be identified and mitigated such that there are no
resulting adverse impacts to ecological functions or processes. The Washington State Department of
Ecology (Ecology) defines no net loss as meaning that no significant adverse impacts to preexisting
ecological function shall occur as a result of proposed shoreline development. Jefferson County
further defines no net loss as “the maintenance of the aggregate total of the county shoreline
ecological functions over time.” Ecological function is defined by the County as “the work
performed or role played by the physical, chemical, and biological processes that contribute to the
maintenance of the aquatic and terrestrial environments that constitute the shoreline’s natural
ecosystem” (JCC 18.25.100(5)(a)).
In the following analysis, habitat and species indicators serve as a proxy for ecological function. By
avoiding impacts to species and the habitats upon which they rely, impacts to ecological functions
will be avoided as well. Log Item 36

3.1 Noise
Changes in noise can result behavioral disturbance or, if loud enough, injury. The following section
describes existing noise conditions and expected effects of the proposed action.
3.1.1 Existing Conditions
Existing sources and levels of airborne as well as underwater noise are described in this section.
3.1.1.1 Airborne Noise
The uplands neighboring the proposed Smersh geoduck farm are rural residential, and they are
zoned as shoreline residential under the current Shoreline Master Plan for Jefferson County. There
are numerous single-family residential houses in the Shine neighborhood which is bordered on the
north side by the heavily trafficked Sstate Route (SR) 104. Between 6,000 and 22,000 vehicles pass
the Shine neighborhood each day on SR 104 (15,000 average annual daily trips) traveling at 60 miles
per hour (WSDOT 2017). Existing noise in the area includes that which is typically found
associated with water-dependent activities (e.g., boat use), residential uses (e.g., vehicle use, lawn
mowers, beach walking), and vehicular traffic. Using the standard that 10 percent of the average
annual daily traffic represents hourly average traffic (WSDOT 2018) leads to 1,500 vehicles per hour
passing near the Shine neighborhood on SR 104. At 60 mph the sound from vehicle traffic is
approximately 75 dBA at 50 feet (WSDOT 2018). This sound level attenuates to approximately 45
dBA at 800 feet which is approximately the halfway point between the Smersh parcel and SR 104.
The estimated noise level based on population density is approximately 40 to 45 dBA (FTA 2006).
3.1.1.2 Underwater Noise
Measurements of ambient underwater noise were recorded at the Hood Canal Bridge in 2004.
Median background peak sound pressure was between 118.2 and 137.5 dBPEAK re 1 μPa and median
root mean squared (RMS) levels were 115 and 135 dBRMS re 1 μPa (Battelle 2005).

3.1.2 Effects of Noise
Noise-generating elements of the proposed project are consistent with existing use of the
surroundings (small boat use and walking on the beach). Both airborne and underwater noise
would be generated from the proposed project when boats are used to access the project site and
during the operation of pumps for harvest on a 5- to 7-year cycle. The potential to affect fish and
wildlife in relation to noise is described below.
3.1.2.1 Effects of Airborne Noise
The proposed project does not include the use of heavy equipment. Access to the site would occur
about once a month, and more frequently during limited periods for activities such as planting or
harvesting. Access would be via the upland parcels or via boat. The outboard motors typically used
on boats used for aquaculture typically create a noise level of about 60 dBA at 50 feet (Berger et al.
2010). However, once at the site, the engine would be turned off until employees are ready to leave.
Small diesel- or gas-powered water pumps with hoses would be used to harvest the geoducks for
several days every 5 to 7 years. While noise levels of the water pumps have not been directly
measured, they are considerably quieter than the outboards, referenced above, that produce a
sound level of 60 dBA at 50 feet. Based on an ambient noise level of approximately 40 dBA to 45
dBA, terrestrial noise associated with the proposed project is expected to attenuate to ambient
conditions 199 to 285 feet from the pumps. The landward margin of the geoduck planting area is
approximately 160 feet from the ordinary high water line, leading to the conclusion that nearby
residents will be exposed to only slight increases in noise if they approach within close proximity to
the shoreline near the project site.
Noise associated with aquaculture operations during planting, maintenance, and harvesting
activities could, if loud enough, result in temporary displacement of birds and/or masking of
communication among foraging birds. Strachan et al. (1995 as cited in USFWS 2009) observed that
marbled murrelets around heavy boat traffic do not appear to be adversely affected by the ambient
noise of urban areas. Other waterbirds have shown behavioral changes in response to noise, but not
to the extent that would cause population-level effects as long as distances of approximately 164
feet to 328 feet are maintained from nesting habitats (Carney and Sydeman 1999, Borgmann 2010).
Because bald eagles are a state sensitive species in Washington, and protected under the federal
Bald and Golden Eagle Protection Act, there is an emphasis on ensuring that shoreline activities, in
general, do not disturb eagles. WDFW studied the response of nesting bald eagles for a 2-year
period (1993-1994) in relation to recreational pedestrian activity and wildstock geoduck harvest
activities within eight territories in Puget Sound (Watson et al. 1995). Eagles flushed in response to
4 percent of 890 potential disturbances, and only 1 of 34 responses was a result of geoduck harvest
activities. Effects to eagle foraging from geoduck harvest activity was considered statistically
Log Item 36

BDN Habitat Management Plan and No Net Loss Report
Page 11
insignificant at the frequency tested 1, and eagles tended to forage evenly throughout the day with
or without a harvest vessel present. Similar effects are anticipated due to the proposed project.
The threshold for masking marbled murrelet communication is an in-air noise level of 29 dB
sensation level (SL) or 29 dB above ambient noise level (Teachout 2013). This threshold was
informed by two critical hearing demands: (1) communication between conspecifics (at-sea or in
terrestrial habitat), and (2) detection of the presence of corvid predators in terrestrial habitat. It is
unlikely that the noise generated by the proposed geoduck aquaculture operation would result in
masking marbled murrelet communication because the use of water pumps during a wet harvest
(the loudest noise source proposed for the project) is expected to increase noise levels by 15 dBA to
20 dBA above ambient noise levels (assuming 60 dBA produced by the water pump and 40 to 45
dBA ambient noise).
Considering the distances from nesting sites from the proposed project area, negative effects
associated with increased human presence are not anticipated at this site. Even if some short-term
avoidance behavior is observed, there is nothing to indicate that this reaction would impact the
overall foraging ability of birds present in the project area. Therefore, it is unlikely that such
temporary displacement from foraging activities in the limited project area would result in reduced
foraging success, nesting success, or fitness of overwintering birds. This concurs with the
conclusions reached by USFWS (2016), that determined exposures and effects of aquaculture-
related noise to marbled murrelets are insignificant.
3.1.2.2 Effects of Underwater Noise
Underwater noise would also be generated from the motors on boats used to transport gear and
personnel to the project area and the small engines used for the water pumps during a geoduck
harvest. Underwater noise thresholds for fish, cetaceans, pinnipeds, and marbled murrelets are
presented in Table 1.

To estimate underwater noise that might result from geoduck aquaculture, we reviewed Table 3.73
of Wyatt (2008) to find a close approximation of the underwater noise generated from boats that
would be used for the proposed project. In order to estimate the worst-case scenario for underwater
noise, the parameters used for this analysis were the 21-ft Boston Whaler vessel with a 250
horsepower Johnson 2-cycle outboard motor operating at full speed and producing sound
measured at 147.2 dB RMS re 1μPa at 1 meter. Following Equation 1, underwater sound of this level
attenuates to the disturbance sound level for marine mammals 213 feet from the boat. Sound levels
produced by the boat do not reach injury levels for any marine mammal group. Nor do sound
levels reach disturbance or injury levels for murrelets and fish.
Equation 1 R1 (in meters) = R2 (in meters)*10((V-120)/15)
R1 = 1m*10(147.2 dB-120 dB)/15)
R1 = 65 m (213 ft)
Where:
R1 = range in meters of the sound pressure level; R2 = distance from the sources of the initial
measurement; V = transmission loss; and dB = decibels
3.1.3 Summary of Noise Effects
According to NMFS’s 2009 assessment of potential impacts to endangered species due to geoduck
aquaculture activities, “A very low level of vessel operations will be associated with the
aquaculture activities (small and larger work boats and barges). Vessels would remain relatively
immobile until work is complete, with minimal sound and insignificant potential for disturbance.”
There is no evidence that increases in either airborne or underwater noise from the use of boat
motors or water pumps associated with the rearing and harvest of geoducks would result in
negative effects to fish and wildlife species. Noise resulting from aquaculture operations
throughout Washington State was reviewed with respect to potential effects to Endangered Species
Act (ESA-listed fish, marine mammals, and marbled murrelets (NMFS 2009, USFWS 2009, NMFS
2011). These reviews found that noise levels did not exceed disturbance thresholds that would
Log Item 36

Page 13
affect foraging, migration, reproduction, or fitness for any of the ESA-listed species in Puget Sound.
The proposed shellfish aquaculture operation in Squamish Harbor would not significantly alter
noise above existing background conditions. Therefore, harvest operations are not anticipated to
increase underwater noise to a level that will result in a loss of ecological functions
3.2 Water Quality
This section describes existing water quality conditions and the expected effects of the proposed
project.
3.2.1 Existing Conditions
Water quality effects are a function of water circulation (or flushing rate and transportation) and
inputs into the system. Due to its proximity to the entrance to Hood Canal, Squamish Harbor
flushes quickly compared to southern Hood Canal. No waters near the project area are listed on the
Federal Clean Water Act Section 303(d) list (Ecology 2018), indicating that upland sources of
pollution are low and circulation maintains good water quality parameters.
3.2.2 Effects to Water Quality
Potential effects to water quality and fish and wildlife species or their habitat are different for the
various phases of potential aquaculture activities. The following discussion is broken down into (1)
filtration effects and (2) harvest effects.
3.2.3 Filtration Effects
Per Thom et al. (2008), Pacific Northwest estuaries are light limited, which reduces the depth at
which eelgrass and other light-dependent species (e.g., macroalgae/kelp) can be successful.
Shellfish aquaculture can result in a beneficial reduction in turbidity due to removal of
phytoplankton and particulate organic matter through filtration (Peterson and Heck 2001, Newell
and Koch 2004, Cranford et al. 2011). By consuming phytoplankton and particulate organic matter,
shellfish decrease turbidity, thereby increasing the amount of light reaching the sediment surface
that is available for photosynthesis (Dame et al. 1984, Koch and Beer 1996, Newell 2004, Newell and
Koch 2004). Improvements to water clarity and light penetration can improve habitat conditions
that promote the growth of submerged aquatic vegetation (SAV) and other aquatic vegetation.
A large body of literature indicates that shellfish aquaculture, or the presence of a dense bivalve
community, may provide some control of human nutrient loading to water bodies (Newell 2004,
Shumway et al. 2003, Newell et al. 2005, Burkholder and Shumway 2011, Kellogg et al. 2013, Banas
and Cheng 2015, Bricker et al. 2015). Bivalves remove more nutrients from the water column than
they input as biodeposits, which can have a net benefit to water quality. As bivalves filter organic
matter from the water column, they assimilate nitrogen and phosphorus into their shells and tissue.
When shellfish are harvested, the sequestered nutrients are permanently removed from the system.
According to Newell (2004), this process of bioextraction is one of the only methods available that
Log Item 36
Page 163 of 218
BDN Habitat Management Plan and No Net Loss Report
Page 14
removes nutrients after they have entered an aquatic system, which can then make that system
more resilient to nutrient loading and, ultimately, decreases in dissolved oxygen. High nutrient
loading, and resulting decreases in dissolved oxygen, are a known problem in Hood Canal.
Similarly, bivalve filter-feeding also serves an important role in improving water quality conditions
through benthic-pelagic coupling, which is when biodeposits become incorporated into surficial
sediments, and microbially mediated processes facilitate nitrification-denitrification coupling to
permanently remove sediment-associated nitrogen as nitrogen gas.
The amount of benefit to water quality is dependent on species-specific filtration rates. A recent
effort to calculate filtering capacity within south Puget Sound (Ferriss 2015) compiled clearance
rates for Pacific oyster, Manila clam, and geoduck (Table 2). According to Banas and Cheng (2015),
a modeling study that used the data compiled by Ferriss (2015), the potential for local control by
shellfish was shown to be possible in areas with reduced circulation such as Henderson, Eld,
Totten, Hammersley, and upper Case inlets, and Oakland Bay. While Banas and Cheng’s study
focused on southern Puget Sound, Hood Canal exhibits similar circulation patterns and clearance
rates when compared to southern Puget sound. Therefore, shellfish filtration could have a positive
influence on local water quality parameters, even if small compared to the inputs into the system
from residential development, municipal wastewater, agriculture, or other non-point sources.

An example of the potential benefits offered by shellfish filtration and nutrient sequestration is
provided by Kellogg et al. (2013), who partially quantified the removal of nutrients from the water
column at a subtidal oyster reef restoration site compared to an adjacent control site in the
Choptank River within Chesapeake Bay, Maryland. The authors indicated that denitrification rates
at the oyster reef in August were “among the highest ever recorded for an aquatic system.” In
addition, a significant portion (47% and 48%) of the available nitrogen and phosphorus were
sequestered in the shells of live oysters and mussels. An ancillary benefit of the shellfish reef
structure, which is also true for shellfish aquaculture, was that the structure and faunal composition
provided ample microhabitats for communities of nitrifying microbes. One of the conclusions by
Kellogg et al. (2013) was that oyster reef restoration could be considered a “safety net” to reduce
additional downstream impacts to water quality. Because geoduck aquaculture provides many of
the same benefits, with the added benefit of the total removal of anthropogenically derived
nutrients at harvest, commercial shellfish aquaculture can be considered a net benefit to water
quality ecosystem functions. Log Item 36

3.2.4 Harvest Effects
During harvest, suspended sediment and turbidity can be increased for a short period near the
harvest activity. Harvest events are limited in space (about 0.1 acre per day), duration (4 to 6 hours
per day), and occurs infrequently (once every 5 to 7 years) compared to the entire culture cycle. The
intensity and duration of turbid conditions are related to the concentration of suspended sediment,
suspended sediment grain size, water temperature, currents, and tidal flow conditions at the site
(NMFS 2009). Golder (2016) modeled sediment movement and suspension of sediment (primarily
sand) disturbed during a geoduck harvest in Case Inlet. Sediment particles were shown to settle
back to the bed rapidly and only a minor fraction was transported a distance of about 300 feet. This
result is consistent with total suspended solids (TSS) collected by Short and Walton (1992) during a
geoduck harvest in the Nisqually Reach, where it was noted that most sediment was deposited
within 3 feet of the harvest hole, and only “small quantities of material” were transported beyond
150 feet from the harvest zone. TSS measured by Short and Walton (1992) at the harvesting location
ranged from 4 to 21 mg/L. While a visible harvest plume persisted for approximately 30 minutes
after harvest and extended approximately 330 feet down current, almost all TSS measurements
within 131 feet of the harvest were shown to be within 1 mg/L of background TSS.
New research from Fisheries and Oceans Canada, Pacific Biological Station in British Columbia,
Canada, has shown similar or lower effects from wet geoduck harvest events. A 2-year research
program in both intertidal and subtidal habitats reported that the measurable sediment plume
generated during a geoduck harvest event was generally limited to within approximately 16 feet of
the harvest plot, and TSS levels were similar to those reported during typical storm conditions (Liu
et al. 2015). In addition, a harvest event did not result in significant changes to sediment grain size
down-current.
Cornwell et al. (in review) evaluated the nutrients released from a typical commercial geoduck
harvest using low-pressure water hoses. The study found that: (1) the amount of nutrients released
into the water column during harvesting is low, (2) the moderate concentrations of nitrogen and
phosphorus found in sediments and released during harvest make a relatively small contribution to
overall nutrient discharges into Puget Sound, and (3) localized effects are likely to be negligible.
A typical geoduck harvest event is limited in space (about 0.1 acre for 1 day), duration (4 to 6
hours), and occurs infrequently with respect to the entire culture cycle (i.e., 5- to 7-year grow-out
period prior to harvest). In comparison, a typical storm event in Puget Sound occurs once per
month and transports material over thousands of kilometers. Therefore, both the timing and
intensity of activities are well below the natural disturbance regime of a typical Puget Sound habitat
and harvest is not anticipated to result in loss of ecological functions.
Exposure to high levels of suspended sediment can cause behavioral stress in fish (e.g., gill flaring),
sublethal effects (e.g., gill damage, increased susceptibility to disease), or reduced survival and
growth. Newcombe and MacDonald (1991) suggested that a good indicator of suspended sediment
effects is the product of sediment concentration and duration of exposure. Fisher et al. (2008)
Log Item 36
Page 165 of 218
BDN Habitat Management Plan and No Net Loss Report
Page 16
evaluated whether the TSS generated during a harvest event could result in significant effects to
fish using the suspended sediment risk assessment model developed by Newcombe and Jensen
(1996). The results indicate that fish are likely to exhibit avoidance responses to the localized TSS
levels generated during a harvest event. Because there is no confinement of the harvest area (i.e.,
the site is located along an open shoreline) there is no mechanism to entrap fish and expose them to
increased suspended sediments for a significant amount of time.
Published literature that addresses suspended sediment effects to juvenile and larval estuarine
fishes also report limited effects at the concentrations generated during a geoduck harvest event.
Juvenile Chinook salmon have been observed to increase their rates of foraging in relation to
increased turbidity (18-150 nephelometric turbidity units [NTUs]), which was attributed to the
increase in cover provided by turbid waters (Gregory and Northcote 1993, Gregory 1994). The
maximum concentration of turbidity that juvenile Chinook salmon experienced before reduced
foraging was observed was 150 NTUs for individuals that were 2 to 3 inches in fork length
(Gregory 1994). Studies have also reported increased feeding incidence and intensity for larval
Pacific herring at TSS concentrations ranging from 500 mg/L to 1,000 mg/L (Boehlert and Morgan
1985). Boehlert and Morgan (1985) attributed the enhanced feeding to improved “visual contrast of
prey items on the small perceptive scale used by the larvae.” Finally, Griffin et al. (2012) noted that
TSS levels of 400 mg/L did not result in adverse effects for Pacific herring larvae for exposure times
of 16 hours. All of the TSS and turbidity levels noted in these examples are either within or
significantly higher than levels measured during a geoduck harvest, indicating that a harvest
would be unlikely to raise TSS to a level or duration that would have negative effects on salmon
and forage fishes. Also, environmental effects of geoduck harvests have been shown to be similar
to, or less than, the effects of periodic natural storms. Therefore, harvest activities are unlikely to
have a negative effect on fish.
3.2.5 Summary of Effects to Water Quality
Bivalves can improve water quality and mitigate anthropogenic sources of nitrogen in coastal
systems through filtration of nitrogen by absorbing phytoplankton in the water column (Newell
2004, Lindahl et al. 2005, Zhou et al. 2006). Conversely, a harvest event can potentially impact water
quality. Although a harvest event may increase suspended sediment for short periods of time (one
to two tidal cycles), it is typically confined to a small area (from 3 feet to 150 feet from the harvest
area) and occurs infrequently (every 5 to 7 years).
Fish would be expected to either avoid the sediment plume generated during a geoduck harvest or
use the plume as a foraging opportunity. Suspended sediment and turbidity levels measured
during geoduck harvest events were within or lower than the range in which juvenile Chinook
salmon and Pacific herring larvae were observed to successfully forage (Boehlert and Morgan 1985,
Gregory 1994). Overall, effects from suspended sediments are considered insignificant and habitat
may potentially be improved in local areas if shellfish improve water quality conditions. No net
loss of ecological function is anticipated due to water quality impacts from geoduck aquaculture.

3.3 Sediment Quality
This section describes existing sediment quality conditions and the expected effects of the proposed
action.
3.3.1 Existing Sediment Conditions
No sediment quality studies have been completed for the specific project site but the lack of historic
industrial development in Hood Canal indicates that sediment is unlikely to contain deleterious
substances regulated by the state. Substrate at the Smersh site consists mainly of well-sorted, clean
sand.
3.3.2 Effects to Sediment Quality
Bivalve filter feeding serves an important role through benthic-pelagic coupling, which is the
consumption of nutrients (via filtration of phytoplankton) and creation of biodeposits (feces and
pseudofeces). Nitrogen and phosphorus that are not digested are excreted as soluble ammonia and
biodeposits in the form of feces. When these biodeposits become incorporated into aerobic, surficial
sediments, microbially mediated processes facilitate nitrification-denitrification coupling to
permanently remove sediment-associated nitrogen as nitrogen gas (Newell 2004, Kellogg et al.
2013).
The biodeposits created through bivalve filter feeding contribute to organic materials in the
sediment surface, as described above.
A study conducted for the Washington Sea Grant Geoduck Aquaculture Research Program
assessed the influence of geoduck aquaculture on sediment nutrient regeneration (Cornwell et al. in
review). During the culture period of the study, porewater nutrient concentrations of nitrogen and
soluble reactive phosphorus were higher at culture sites than at reference sites. The release of
nitrogen and phosphorus species during harvest resulted in a minor increase in nutrient
concentration of water surrounding the geoduck harvest, suggesting that the liquefication of
sediments does not release a large percentage of the accumulated nutrients in the porewater. The
authors concluded that when extrapolated to all Puget Sound cultivated geoduck harvest on a daily
basis, the harvest release of nutrients represents an inconsequential fraction of anthropogenic
inputs into Puget Sound, leading to the conclusion that geoduck harvest is unlikely to reduce
ecological function due to sediment or water quality effects.
Grounding of vessels may occur occasionally and temporarily during harvest of geoducks. Vessels
would have approximately 20 square feet of ground contact for up to 6 hours per day during
approximately 10 low tide workdays per year. Because the proposed farming area is composed of
well-sorted, clean sand, no effect is anticipated to fish or wildlife habitat. Sand does not support
attachment of flora and fauna that would provide feeding or refuge opportunities for local fish and
wildlife. Additionally, because sand within the proposed planting area is loosely consolidated, any
visible scars or footprints from the grounded vessel would be washed away within one tidal cycle
Log Item 36

Page 18
of the grounding. Impacts from grounding would be similar to what might be expected from an
individual walking the beach at low tide. An occasional crab or fish may become entrapped
beneath the grounded vessel but no long term negative impacts would occur to fish and wildlife
populations nor the habitats upon which they rely for breeding, rearing, migration, or growth to
maturity.
3.4 Sediment Transport and Bathymetry
This section describes existing sediment transport and bathymetry conditions and the expected
effects of the proposed action.
3.4.1 Existing Conditions
Sediment along the north shore of Squamish Harbor is primarily sandy in the lower elevations with
gravel and cobble on the upper intertidal beach. The beach slopes gradually and has a relatively
high exposure to waves, winds, and currents during storm events. East of the project area there is a
high bluff composed of various layers of glacial sediment. The bluff is characterized by massive
erosion that threatens several structures on the top of the bluffs (ESA Adolphson et al. 2008). The
shoreline is classified as unstable recent landslide (Ecology 1978). Net shore-drift is to the west as
indicated by sediment accumulations on the east side of obstacles and the westward prograding
spit at the mouth of Shine Creek ESA Adolphson et al. 2008). In the nearshore, eelgrass beds are
patchy in the intertidal zone and continuous below MLLW. Shoreline armoring is prevalent along
the north shore of Squamish Harbor, with about 26 percent of this reach armored (Jefferson County
2008). A boat ramp extends onto the beach next to the project parcel, with a parking lot located on
fill. The effect of the armoring and boat ramp are unclear, but are likely having at least a minor
effect on sediment erosion and input.
3.4.2 Effects to Sediment Transport and Bathymetry
No dredging or placement of fill is proposed as part of the project. The two types of potential
disturbances associated with shellfish aquaculture that could affect sediment transport and
bathymetry include: (1) addition of gear that slows the transport of sediments, and (2) pulse
disturbances due to effects of harvest activities (Dumbauld et al. 2009). These potential disturbances
are described below.
3.4.3 Addition of Gear
PVC culture tubes used in geoduck clam aquaculture can slow currents near the substrate, resulting
in accumulation of sediment under and around the PVC tubes. Golder (2011) estimated the
potential accumulation of sediment within the tubes from an existing geoduck aquaculture
operation in south Puget Sound. Based on a visual inspection, an average height of 2.5 ±0.5 inches
of sediment accumulation was reported within the 4 inches of tube that was exposed above the
sediment bed. This equates to a volume of approximately 31.4±6.3 cubic inches per tube. Golder
(2011) then calculated net accumulation over a 1-acre area to be approximately 29.3 cubic yards (cy)

of sediment. This minor amount of net accumulation is expected to rapidly redistribute through
wave and current action after 1 or 2 tidal cycles (or a few days with typical wave conditions)
following the removal of PVC culture tubes.
3.4.4 Harvest Activities
During a geoduck harvest, the overlying sediments are loosened around the clam by adding water
through a 0.5-inch- to 0.6-inch-diameter hose. Although this activity results in minor, localized
changes in elevation and sediment grain size, both quickly return to baseline conditions post-
harvest. At Samish Bay, Horwith (2009) reported that minor post-harvest elevation drop was not
evident within 1 month of a harvest. Post-harvest resettling of sediments occurs as water content
decreases, leading to an increase in shear strength and resistance to erosion. In laboratory
experiments with fine-grained marine sediment, resistance to resuspension was shown to double
approximately every 12 hours (Southard et al. 1971 as cited in Short and Walton 1992). Therefore,
the sediment redeposited during a harvest event will tend to regain its original shear strength
within 1 or 2 days after harvest.
Grounding of vessels may occur occasionally and temporarily during harvest of geoducks. Because
the proposed farming area is composed of well-sorted, clean sand, no effect is anticipated to fish or
wildlife habitat. Sand does not support attachment of flora and fauna that would provide feeding
or refuge opportunities for local fish and wildlife. Additionally, because sand within the proposed
planting area is loosely consolidated, any visible scars or footprints from the grounded vessel
would be washed away within one tidal cycle of the grounding. Impacts from grounding would be
similar to what might be expected from an individual walking the beach at low tide. An occasional
crab or fish may become entrapped beneath the grounded vessel but no long term negative impacts
would occur to fish and wildlife populations nor the habitats upon which they rely for breeding,
rearing, migration, or growth to maturity.
3.4.5 Summary of Effects to Sediment Tranport and Bathymetry
In summary, geoduck harvest or the presence of PVC culture tubes does not lead to significant
negative effects to sediment transport or bathymetry. Minor changes in elevation may persist for up
to 1 month, but these effects are considered to be short-term with no lasting changes to the
surrounding sediment structure. The changes associated with geoduck aquaculture operations are
insignificant compared to the dynamic nature of sediment distribution potential (e.g., storms,
littoral drift, etc.) along the shoreline associated with the project area. No loss of ecological function
is anticipated due to changes in sediment transport or bathymetry.
3.5 Migration, Access, and Refugia
This section describes existing migration, access, predation, and refugia conditions and the
expected effects of the proposed project.

Page 20
3.5.1 Existing Conditions
Shine Creek, approximately 1.5 miles to the west supports chum and coho salmon and cutthroat
and steelhead trout spawning. The Shine Creek estuary is likely rearing habitat for natal and non-
natal juvenile pink, chum, coho, and Chinook salmon (ESA Adolphson et al. 2008). A small stream
enters Squamish Harbor near the project site (>150 feet to the north) and is presumed cutthroat
trout habitat (Correa 2003). This small stream does not support salmon because access to upstream
habitat is hindered by (1) the very small size of the stream, and (2) the steep gradient where the
stream flows through shoreline armoring (i.e., boulder riprap). Sand lance spawning has been
documented along the beach to the west of the project and herring are known to spawn in the
eelgrass beds offshore (Penttila 2000, Long et al. 2003).
The project site is a sandy, gravelly beach with no man-made structures. Juvenile salmonids and
other fish may use the intertidal area, when inundated, for migration, access, and refugia.
3.5.2 Effects to Migration, Access, and Refugia
PVC culture tubes are the only material planned for use in aquatic areas for this project. PVC tubes
extend only 3 to5 inches above the substrate surface No other equipment is planned for use in the
project and no excavation or alteration of the beach is planned. Culture tubes will not block
migration or access to habitat in the project area.
The planting area is over 150 feet from the mouth of the nearby stream. All species of Puget Sound
salmon are well documented utilizing estuarine and nearshore habitat in their migrations from
their natal freshwater watersheds to the ocean and back (Duffy et al. 2010). Salmon are known to
feed in habitat similar to that found in the project area, ingesting amphipods, copepods, larval fish,
and terrestrial insects (Fresh et al. 2006). Depending on the tidal cycle, fish can easily swim over, or
around culture tubes if necessary. Many researchers have reported that aquaculture gear is similar
(or superior) to adjacent eelgrass habitat in terms of the diversity and abundance of benthic fauna
and fish (Meyer and Townsend 2000, DeAlteris et al. 2004, Pinnix et al. 2005, Powers et al. 2007).
Sand lance spawn in sandy substrate in the upper intertidal zone between MHHW and +5 feet
(MLLW) (Pentilla 2007). Because project planting, grow-out, and harvest will not extend above +2
feet elevation, access to sand lance spawning habitat will not be reduced.
As long as the gear is properly maintained, PVC geoduck culture tubes in the intertidal area are not
expected to affect migration, access, or refugia pathways for fish that utilize shallow water. The
presence of aquaculture gear may even serve as additional foraging habitat or cover from
predators. Because occasional vessel grounding in the highly dynamic sandy shoreline
environment will be of short duration and occur only occasionally during a 2-year harvest period,
no impacts to areas of fish and wildlife migration, access, and refugia are anticipated. No loss of
ecological function is expected to occur due to effects to migration, access, and refugia.

3.6 Forage Fish
This section describes existing forage fish conditions and the expected effects of the proposed
project.
3.6.1 Existing Conditions
Sand lance spawning has been documented along the beach to the west of the project and herring
are known to spawn in the eelgrass beds offshore (Penttila 2000; Long et al. 2003). Sand lance
spawn in sandy substrate in the upper intertidal zone between MHHW and +5 feet (MLLW)
(Pentilla 2007) and typically select substrate with a diameter between 0.2 and 0.4 millimeters. In the
project area, the substrate found in the elevation range sand lance typically spawn is primarily
gravel, which is sub-optimal for sand lance spawning. A dense eelgrass bed is found in the subtidal
zone at least 16 feet from the proposed planting area.
3.6.2 Effects to Forage Fish
There are two potential effects to forage fish from the proposed geoduck aquaculture operation,
including: (1) spawning habitat could be overlapped, and (2) forage fish spawning areas could
receive suspended sediments during a harvest event. The potential for these effects to be significant
to forage fish or their habitat in the project area are discussed below.
3.6.3 Spawning Habitat Overlap
The proposed culture activities are not located at shoreline elevations where sand lance spawn.
Culture will be confined to the intertidal and subtidal zone below +3 MLLW, while the forage fish
spawn elevation begins at +5 MLLW. Therefore, the proposed project is not expected to impact
spawning habitat of these forage fish species. When the site is accessed by boat, boats would not be
beached above +5 ft MLLW. Boats will be moored or grounded in areas waterward of +5 ft MLLW.
Foot traffic for routine maintenance and beach surveys for debris will use consistent paths and will
not occur where potential forage fish spawning habitat may exist.
In some cases, aquaculture gear can provide a new substrate for herring spawn attachment in an
otherwise unstructured environment. Growers will be trained by a WDFW-certified biologist to
recognize herring spawn. If herring spawn is observed within the geoduck farm, then those areas
will be avoided until the eggs have hatched. Vessels will not be grounded in areas where herring
spawn is observed. This conservation measure has been adopted by the Corps as part of the ESA
consultation process with the Services on the Programmatic Consultation for Shellfish Activities in
Washington State Inland Marine Waters (NMFS 2016a, USFWS 2016).
Therefore, the proposed project will not result in a loss of ecological function due to the project
overlapping forage fish spawning habitat.
Log Item 36

BDN Habitat Management Plan and No Net Loss Report
Page 22
3.6.4 Sediment Mobilization
If forage fish do spawn near the project area, there is a low potential for adversely impacting
spawning beds with sediment mobilized during harvest. Fines make up a small percentage of the
farm substrate, and sands (because they are denser) drop out of the sediment plume within a few
meters (Short and Walton 1992, Golder 2011). Therefore, there will be no loss of ecological function
due to effects to forage fish spawning habitat resulting from sediment mobilization.
3.6.5 Summary of Effects to Forage Fish
Because the project does not overlap sand lance spawning habitat, and because farming activity will
halt if herring spawn are observed within the project area, no loss of ecological function is
anticipated due to negative effects to forage fish spawning. Additionally, because sediments
mobilized during geoduck harvest settle out of the water column within a few feet of harvest
activity, no net loss of ecological function is anticipated due to mobilized sediment.
3.7 Benthic Infauna and Epifauna
This section describes existing benthic infauna and epifauna conditions and the expected effects of
the proposed action.
3.7.1 Existing Conditions
Observations of epifauna in the proposed project area were consistent with Puget Sound sandflat
habitats (Dethier 1990, Dethier and Schoch 2005). Species observed at the project site include
various amphipods, various isopods, various polychaete worms, sand sole, English sole, various
sculpins, various shrimp, Dungeness crab, red rock crab, and various hermit crabs,
3.7.2 Effects to Benthic Infauna and Epifauna
Geoduck aquaculture may affect the benthic faunal community, including community changes
during: (1) culture tube placement and use in 1st two years of grow out, and (3) harvesting. The
effects of each action, the relative recovery period, and potential effects to benthic fauna are
discussed below.
3.7.3 Culture Tube Placement Effects
Placement of PVC culture tubes is not expected to significantly affect benthic epifauna. Once the
tubes are placed, they are rapidly encrusted with epibiota that create a reef-type structure and a
biogenic source for associated food organisms of juvenile salmonids (Cheney 2009, VanBlaricom et
al. 2013). Specific studies evaluating the use of geoduck farms by salmonids and other fish are
ongoing. However, based on shellfish aquaculture studies in similar sandflat habitats, the effects
from culture tubes are likely beneficial to salmonids and other fishes because of the additional food
resources available (Cheney 2009, NMFS 2011, NMFS 2016b, USFWS 2016). In fact, NMFS (2016b)
concluded that increased densities of benthic infauna at intertidal geoduck clam aquaculture sites
may persist even after removing protective tubes. For example, at one aquaculture site in southern
Log Item 36
Page 172 of 218
BDN Habitat Management Plan and No Net Loss Report
Page 23
Puget Sound, ENVIRON 2008 (as cited in NMFS 2016b) found the average number of infaunal
benthic organisms per sediment core from an unprotected seeded area was greater than the density
of infaunal benthic organisms found in a reference area located outside of the aquaculture site.
Thuesen and Brown (2011, as cited in NMFS 2016b) observed an increase in biodiversity of benthic
fauna in an intertidal geoduck farm using PVC tubes, and species richness was significantly higher
compared to a control site and compared to a geoduck farm without tubes. Data from the Pacific
Shellfish Institute (Cheney 2009) documented up to a 30 percent increase of harpacticoid copepods
(e.g., typical salmonid prey items) on PVC tubes at an existing geoduck aquaculture plot in Spencer
Cove on Harstine Island.
3.7.4 Harvest Effects
Shellfish harvest disrupts the sediment and results in the loss of some benthic fauna (Hall and
Harding 1997, Ferns et al. 2000), although that does not mean that the loss is a significant impact to
that resource. The recovery rate of infauna varies in response to the timing and magnitude of the
disturbance as well as the location of the site to populations of organisms and the mobility of
organisms affected (Dernie et al. 2003). Intertidal habitats are exposed to a wide range of natural
disturbance regimes that are dominated by physical processes such as tides, storm-generated
waves, inter-annual variation in climate, and nearshore sediment transport. It is generally assumed
that benthos found in more dynamic sand and gravel habitats will recover more quickly following
physical disturbance than those found in less energetic muddy habitats based on the adaptive
strategies of the respective assemblages found in these environments (Kaiser et al. 1998, Ferns et al.
2000). Microcosm studies appear to support this hypothesis (Dernie et al. 2003). In general, benthic
infauna recovered very quickly (weeks to months) in terms of both diversity and abundance from
small-scale disturbances, especially within clean sand communities.
Price (2011) and VanBlaricom et al. (2015) reported that potential effects to benthic invertebrates
from a geoduck harvest event are within the natural disturbance regime. This work compared the
benthic community within harvested and non-harvested plots and found that effects to benthic
infauna during geoduck harvest are similar to effects resulting from wind and wave energy due to
natural storms. Detectable disturbances quickly become indistinguishable from control plots
(VanBlaricom et al. 2015). Recovery of the benthic infauna is relatively rapid after a geoduck
harvest event because infauna are still preserved in roughly the same location, leading to rapid
recolonization (Price 2011). In addition, because a harvest cycle occurs every 5 to 7 years, there
would unlikely be compounded effects due to repeated harvesting of the same area (Liu et al. 2015).
The main conclusion from VanBlaricom et al. (2015) was that communities in Puget Sound are well
adapted to accommodate various types of disturbance. Because the frequency of disturbance from
geoduck harvest occurs at a much lower rate than storm events, infaunal and epifaunal populations
are unlikely to experience long-term negative effects. Based on this evaluation, it was determined
that there were no long-term measurable effects to resident populations of invertebrates from
geoduck harvest, and the intensity of potential effects was equivalent to natural disturbances.

BDN Habitat Management Plan and No Net Loss Report
Page 24
3.7.5 Summary of Effects to Benthic Infauna and Epifauna
Overall, the research indicates that the benthic infaunal and epifaunal community is not affected or
returns to baseline, or near baseline conditions, once the gear is removed or harvest is complete
(VanBlaricom et al. 2013, Price 2011, McDonald et al. 2015, Liu 2015, VanBlaricom et al. 2015). Small
benthic invertebrates produce more than one generation per year and thus have rapid
recolonization rates. Intertidal species have adapted to habitat changes. Chronic low-intensity or
sporadic medium-intensity intertidal substrate disturbances are within the range of “behavioral or
ecological adaptability” (Jamieson et al. 2001). Therefore, no net loss in ecological function is
anticipated due to impacts to benthic infauna and epifauna.
3.8 Waterfowl
3.8.1 Existing Conditions
Embayments of North Puget Sound provide important breeding and rearing habitat for waterfowl
and shorebirds. A variety of diving and dabbling ducks are likely to use the shorelines near the
proposed project for foraging, breeding, and loafing. The clean, well-sorted sand at the proposed
project site does not currently provide good foraging habitat for diving and dabbling ducks. The
sandy beach may provide foraging opportunities for shorebirds during low tides.
3.8.2 Summary of Effects to Waterfowl
Studies of waterfowl use in aquaculture farms have shown either positive impacts (e.g. increasing
avian species richness and abundance due to increased foraging opportunities) or benign impacts
(eliciting no significant difference in use from natural beds). Through their foraging habits,
migrating marine shorebirds can significantly alter the community structure of wild bivalve
populations in soft-bottom intertidal areas (Lewis et al. 2007). At shellfish aquaculture sites, some
species of marine birds feed directly on the shellfish products themselves (Dankers and Zuidema
1995), while others feed on the macrofauna and flora that colonize shellfish aquaculture gear
(Hilgerloh et al. 2001). Shellfish growers have documented numerous bird species foraging on their
shellfish beds, including scoters, dunlins, killdeer, godwits, sand pipers, eagles, great blue herons,
and gulls. Figure 3 presents a few of the species mentioned using shellfish beds for foraging habitat.
Due to the relatively recent history of geoduck aquaculture, and the fact that intertidal geoduck
beds are exposed for a short portion (approximately 6%) of the culture cycle, there are limited
examples that illustrate how birds interact with geoduck aquaculture gear. However, there is both
anecdotal evidence and some photography to show potential interactions. One of the best examples
is the mutually beneficial relationship between shellfish aquaculture practices and scoters. In some
areas, geoduck nursery tubes, oyster crops, and culture gear will get coated with sets of mussels.
The young mussels attract scoters that provide a service to growers by grazing the fouling mussels
off the crops and gear. At the Foss farm in Case Inlet, crews removed nets and when they returned
the following night to clean out the mussels, they were gone. They removed more nets and
deployed a GoPro® camera to discover scoters were cleaning off what ended up being thousands of
pounds of mussels (Figure 4). Log Item 36

Shorebirds may be temporarily displaced from the farm during site inspections or harvesting but
there are numerous undisturbed shorelines in the near vicinity that provide foraging and loafing
opportunities during such short duration and temporary activities.
3.9 Aquatic Vegetation
This section describes existing submerged aquatic vegetation (SAV) conditions and the expected
effects of the proposed action.
3.9.1 Existing Conditions
A dense bed of eelgrass extends from approximately -3 ft MLLW, waterward of the project area to
an unknown depth. A narrow band of sparse, patchy eelgrass is adjacent to the dense native
eelgrass bed between approximately -2 and -3 feet MLLW. No native eelgrass was identified
landward of the upper edge of the patchy eelgrass bed. Several very sparse patches of non-native
dwarf eelgrass (Zostera japonica) were observed distributed throughout the project area.
Log Item 36
Page 176 of 218
BDN Habitat Management Plan and No Net Loss Report
Page 27
Macroalgae beds are not found in or near the project area. Typical of sand- and silt-dominated
habitats in Puget Sound, ulvoids were present at a very low density (<2% surface coverage)
throughout the mid- and low-intertidal zone (approximately +2 to -2 feet MLLW) attached to hard
objects such as derelict clam shells.
3.9.2 Effects to Aquatic Vegetation
Macroalgae density is anticipated to increase in the project area due to geoduck farming as the PVC
culture tubes provide solid substrate required by macroalgae for attachment and growth.
Because the project will be located outside of a 16-foot protective buffer from native eelgrass, no
negative effects are anticipated to occur to eelgrass due to the proposed project. No net loss in
ecological function will occur due to impacts to aquatic vegetation.
3.10 Plastics and toxicity
3.10.1 Existing Conditions
Plastics are commonly used in the marine environment. A few examples of marine plastics are
buoys, floats, nets, fishing line, and boat components. Increased generation of both macroplastics
and microplastics have been identified as potential as concerns for aquaculture equipment.
Macroplastics are defined as any solid material greater than 5 millimeters (mm) or 0.2 inches in
diameter, while microplastics are materials less than 5 mm that are primarily composed of synthetic
polymers (Baker et al. 2011, Davis and Murphy 2015).
Microplastics may enter the marine environment from primary sources (e.g., pellets in facial scrubs
entering marine waters through water treatment plant effluent), or from the disintegration of larger
plastic materials. Microplastics were sampled from the upper 1.6 ft of the Puget Sound water
column by the Center for Urban Waters and the University of Washington (Baker et al. 2011). The
study reported that microplastics are ubiquitous in all coastal waters. Within Puget Sound,
microplastic concentrations were found to be highly variable in space and time, did not appear to
be correlated to specific source locations, and were similar to levels in the open North Atlantic and
Eastern Pacific. Comparatively, Davis and Murphy (2015) collected material directly from beaches
rather than from the water column. This study reported that the majority of microplastics observed
were located in north and central Puget Sound, typically in close proximity to marinas and urban
centers. Styrofoam was by far the majority (75% of the count) of anthropogenic microdebris found
in these areas, followed by plastic fragments (9%) and glass (12%). There appears to be a strong
positive correlation between the areas of high microplastic abundance and population density.
3.10.2 Summary of Effects from Plastics and Toxicity
Concerns have been raised at Shoreline Hearings Board hearings regarding the potential for
aquaculture activities to release micro- or macro-plastic debris or to leach metals into the
environment (Baker 2012). No PVC is planned for use in this project so leaching of metals or other
Log Item 36
Page 177 of 218
BDN Habitat Management Plan and No Net Loss Report
Page 28
toxic chemicals from PVC will not occur. PVC culture tubes planned for this project are made of
high-strength, long-wearing High Density Poly-Ethylene (HDPE) that, once lodged into the
sediments, are very difficult to dislodge.
The potential to create microplastics was thoroughly reviewed by Dr. Joel Baker in 2012. Dr. Baker
found that PVC tubes, which are much less abrasion resistant than HDPE, are unlikely to degrade
based on the low ultraviolet exposure (i.e. tubes are under water most of the time), low wave
energy, and debris management plans (Baker 2012). To confirm that microplastics were not created
within a tube field, bulk sediment samples were taken from existing geoduck tube fields and tested
in an EPA-approved lab. Dr. Schenk (2011) reported that there was no evidence of microplastics in
the sediment samples. Further confirmation that microplastics are not created due to geoduck
aquaculture was based on a review of stomach samples from fish collected in geoduck tube fields.
Dr. VanBlaricom (2013) testified that, out of 235 fish collected from geoduck aquculture farm, there
was no evidence of microplastics in their stomachs. While there are no known data specific to the
potential to generate microplastics from the use of HDPE materials, there is no evidence that
microplastics are a significant issue driving net loss of fish or wildlife habitat in Puget Sound (Davis
and Murphy 2015). According to Schoof (pers. comm., 2015), the life cycle of HDPE used for
aquaculture is much longer than manufacture’s specifications (e.g., decades vs. 2 years). Therefore,
due to HDPE’s strength and integrity, it is unlikely that use of HDPE materials would significantly
contribute to the generation of microplastics.
In a review of potential impacts of microplastics in the marine environment, Andrady (2011)
commented that microplastics were most likely generated on beaches, which would have extended
exposure to light and weathering if not collected. The author mentioned that beach cleanups are an
effective mitigation strategy to avoid or limit the creation of microplastics. He concluded his
comments on beach cleanup by stating, “Beach cleanup therefore can have an ecological benefit far
beyond the aesthetic improvements of the beaches, and by reducing microplastics, contributes
towards the health of the marine food web.” The conditions of farm approval include maintenance
of the project area, which would include cleaning up unnatural debris.
In summary, with proper farm management, it is unlikely that geoduck aquaculture farming would
result in the creation of macro- or microplastic debris. There is no evidence that existing farms in
Puget Sound are creating plastics debris or resulting in metals leaching into the sediment from the
use of PVC tubes or HDPE materials. Therefore, with proper farm management, no net loss of
ecological function is anticipated from plastics or toxicity.
3.11 Summary of Potential Effects

1.0 INTRODUCTION
BDN, Inc. has leased parcel 721031007 (Smersh parcel) on Shine Road west of the Hood Canal
Bridge and is proposing to operate a geoduck farm at the site (Figure 1). A conditional use permit
is requried by Jefferson County and, as part of the permit application, a visual assessment has been
requested by the County purssuant to Jefferson County code 18.25.440(4)(f). The following
document presents an assessment of the potential effects to nearby uses and aesthetic qualities of
the shoreline that might occur due to geoduck aquaculture operations on the Smersh parcel.
BDN, Inc proposes to plant up to 5.15 acres of geoducks at the site between +2 feet and
approximately -2 feet relative to mean lower low water (MLLW) (Figure 2). The lower boundary of
planting has been determined based on the location of the eelgrass bed below approximately -2
feet MLLW (Confluence 2016). Geoduck will be planted outside of a 16 foot horizontal buffer from
the eelgrass bed (Figure 2). To protect geoduck seed from predators, PVC tubes 4” in diameter by
10” long would be placed into the sandy substrate at low tide, while the tidelands are exposed,
before any geoduck seed is planted. Tubes would be placed at an approximate density of 1 tube
per square foot with 3” to 5” of the tube exposed above the substrate. A low pressure water hose
may be used to loosen the substrate sufficiently to properly insert the PVC tubes. Tubes will be
labeled with contact information for BDN. 12-25 workers will work to insert these tubes during
each approximately 5-hour shift. This will allow for approximately 6,000-10,000 tubes to be placed
per day.

Geoduck seed will then be obtained from a certified hatchery and typically planted in the installed
PVC tubes when 4-5 mm in size. The juvenile geoducks will be placed in the installed PVC tubes
by divers during times when the tubes are submerged. No water jets will be used during
placement of the seed in the PVC tubes. The tubes will be clipped shut at the top by the divers,
using plastic clips, after the seed has been planted. Planting will begin in spring and continue
through fall. Planting activities will occur once per year, typically in June or July, over a period of
20-25 days.
No netting will be installed over the tubes, and no rebar or other materials will be used in
connection with the planting maintenance or harvest activities. No fill materials or other
nursery/grow-out structures will be installed on the site.
2.0 VISUAL IMPACT ASSESSMENT METHOD
2.1 Overview
This visual assessment follows protocols and methods outlined in the Department of Ecology’s
Aquaculture Siting Study (Ecology 1986) developed by the State of Washington to assess visual
effects that might be experienced due to aquaculture activities. In Ecology’s study, they
incorporated and expanded upon visual assessment techniques identified by the U.S. Forest
Service (USFS) and U.S. Bureau of Land Management (BLM) and refined the applicable techniques
Figure 2. Proposed Geoduck Planting Area and Distances from High Water
Log Item 36
Page 193 of 218
Smersh Farm Visual Assessment
October 2019 Page 3
to focus on assessments of aquaculture. The result is the Visual Assessment Workbook which
provides an analytical process for evaluating visual impacts of aquaculture.
The USFS identified nine assumptions related to visual quality that were adopted by Ecology in
their analytical process to assess visual impacts of aquaculture:
1. People have certain scenic expectations
2. View duration is critical;
3. Number of viewers is critical;
4. Diversity increases scenic value;
5. Retention of distinctive character is desirable;
6. Each setting varies in capacity to absorb visual alteration;
7. Landmarks/focal points receive critical scrutiny;
8. Viewing angle is critical; and
9. Viewing distance is critical.
The BLM identified three principles related to visual quality that were adopted by Ecology in their
analytical process to assess visual impacts of aquaculture:
1. Landscape character is primarily determined by the four basic visual elements of form,
line, color, and texture. Although all four elements are present in every landscape, they
exert varying degrees of influence.
2. The stronger the influence exerted by these elements, the more interesting the landscape.
3. The more visual variety in a landscape, the more aesthetically pleasing the landscape.
Variety without harmony, however, is unattractive, particularly in terms of alterations
(cultural modifications) that are made without care.
The principles and assumptions outlined by the USFS and BLM were incorporated by Ecology into
a visual assessment method that inventories the surrounding landscape to quantify visual
characteristics of the landscape and the proposed aquaculture operations, and incorporates the
landscape inventory scores within an analysis matrix to arrive at an overall visual impact score.
2.2 Inventory
The Ecology defined inventory of visual characteristics includes three categories: scenic quality,
sensitivity level, and visibility. Scenic quality incorporates individual rating scores of
environmental condition, spatial definition, and adjacent scenery to determine a high, moderate,
or low scenic quality rating. Site sensitivity level is an accounting of the number of potential
viewers and their potential view duration of the project area (i.e., Smersh geoduck farm). The
visibility category identifies key observation points and evaluates the visibility of the aquaculture
site based on obstructions, distance from viewer, and the amount of the viewers cone of vision
taken up by the aquaculture activity (Figure 3). Log Item 36

2.3 Analysis
In the analysis step, the scores from the inventory of scenic quality, sensitivity level, and visibility
are incorporated into an overall score to determine the severity of the probable visual impact. The
four classifications of visual impact are:
1. Class I (Severe Visual Impact) – Any permanently visible aquaculture facility will likely
have a severe visual impact that cannot be mitigated for. This category is applicable only in
wilderness areas.
2. Class II (High Visual Impact) – Areas where permanently visible aquaculture facilities will
likely be visually obtrusive.
3. Class III (Moderate Visual Impact) – Areas where permanently visible aquaculture facilities
will be visually evident.
4. Class IV (Low Visual Impact) – Areas where existing visual disruptions dominate or areas
with low sensitivity/visibility.

3.0 FINDINGS
A site visit was made to the Shine neighborhood and surrounding locale on April 18, 2018 during a
daylight low tide to inventory the scenic quality, sensitivity level, and visibility of the area within
the viewshed of the proposed Smersh geoduck farm. A hard copy of the visual assessment
workbook was consulted during the site visit and notes and scores were cataloged in the
workbook (Appendix A) for incorporation into this assessment.
3.1 Scenic Quality
Scenic quality is a combination of environmental condition, spatial definition, and adjacent
scenery. Each of these elements is described in more detail below.
Summary Category Rating: Moderate scenic quality – Areas with a combination of some
outstanding features and some that are fairly common.
3.1.1 Environmental Condition
Environmental condition is the capacity of the landscape to accept human alteration without
losing its natural visual character.
3.1.1.1 Environmental Condition Rating
Individual Element Rating: Moderate
Environmental condition was rated as Moderate based on distinctive landscape character, the
nearby public park and public use area, and areas with visible evidence of human activity, but not
at a dominating level. The Smersh site is located on a heavily altered shoreline in a medium-
density, residential neighborhood. The shoreline has been altered by rip rap hardening, there is a
concrete boat ramp and gravel parking lot in the adjacent public property, riparian trees have been
removed from a number of the adjacent properties to increase private views, and the paved
roadway is adjacent to the shoreline for approximately 1 mile to the west of the Smersh parcel.
3.1.2 Spatial Definition
Spatial definition is the degree of spatial enclosure and volume created by the flat plane of the
water body and the surrounding landforms.
3.1.2.1 Spatial Definition Rating
Individual Element Rating: Moderate
Spatial definition was rated as moderate based on the shoreline form with concave embayments ½
mile to 2 miles across. Squamish Harbor is approximately 2 miles across at the Smersh site and
Hood Canal is approximately 3 miles across at the Smersh site.

3.1.3 Adjacent Scenery
Adjacent scenery refers to the adjacent shoreline edge, landform, and vegetation which define the
embayment. Influence, detail, and clarity diminish with distance. In general, impact of this
variable increases as the degree of enclosure increases, or as the embayment size or the distance to
the opposite shoreline decreases.
3.1.3.1 Adjacent Scenery Rating
Individual Element Rating: Low
Adjacent scenery was rated as low based on the lack of variety in form, line, color, and texture.
Trees obscure views from neighboring residences, clear cutting is visible in the managed forests to
the west, managed forests are visible on all adjacent shorelines, and most shorelines being greater
than 1 mile from viewpoints.
3.2 Sensitivity Level
Sensitivity level refers to the number of potential viewers, adjacent travel routes, use areas, or the
amount of existing residential development.
Summary Category Rating: Low – few adjacent travel routes and medium-density residential
development. Further, because geoducks will be located in the intertidal zone, they will be
underwater for the majority of the time and the duration when they are visible will be short. This
rating is described in more detail below.
3.2.1 Number of Viewers
Individual Element Rating: Low
This element was rated as low because the potential number of viewers of the Smersh Site is low.
At low tide, the upper margin of the geoduck planting at +2 feet elevation is visible from only 12
residences while the lower margin of the geoduck planting at -2 feet elevation is visible from only
20 residences (See Appendix B – Photos 11 and 12). The site is not visible from the heavily-
travelled state route 104 and, while it may be visible from Shine road during some tidal stages,
Shine road is a neighborhood access route and not heavily travelled. The neighboring park is little
more than a boat ramp and gravel parking lot. The boat ramp is only useable during high tide,
when the PVC geoduck tubes would be submerged, so there is little opportunity for visitors to see
aquaculture activities.
3.2.1 View Duration
Individual Element Rating: Low
It is important to note that tides low enough to expose the planting area follow a seasonal pattern
in the Puget Sound region. Larger-magnitude summer low tides occur during daylight hours,
Log Item 36
Page 197 of 218
Smersh Farm Visual Assessment
October 2019 Page 7
while winter low tides occur at night. Therefore, PVC geoduck tubes are more visible in summer,
and minimally visible in winter.
While the presence of medium-density residential development may lead to a moderate score for
the Sensitivity Level category, aquaculture equipment and activities are only visible during
daylight low tides for a small percentage of each month. Figure 4 illustrates that the upper margins
of the geoduck planting area are visible a maximum of 16% of any single month (Chart A) and the
entire planted area is visible a maximum of only 2% of a month (Chart B) (NOAA 2018).
A. B.
Figure 4. Proportion of month the upper margin (Chart A) and lower margin (Chart B) of the
geoduck planting will be visible based on NOAA tide data from Jan 1, 2012 to Dec 31, 2017.
Figure 5 presents the tidal range in Hood Canal throughout the year overlaid by the farm
boundary. It should be noted that, while geoduck will be planted between +2 feet and -2 feet
elevation, the geoduck tubes may extend up to 7 inches (0.6 feet) above the sediment so the farm
boundary has been shown between -1.4 feet and +2.6 feet to represent the tidal elevation of the
PVC geoduck tubes. As can be seen in Figure 5, tidal elevation seldom goes as low as the upper
farm boundary and even more rarely goes as low as the lower farm boundary, further illustrating
that the aquaculture activities will be exposed only a minor portion of a month.

3.3 Visibility
Visibility is a combination of the following elements, which are discussed in more detail below:
view obstruction, distance offshore/observer position, and viewshed coverage.
Summary Category Rating: Low
Visibility is rated low due to obstructed views from vegetation and landform as well as large
distances between geoduck planting area and potential viewers. Also, geoduck tubes have very
low relief and natural macroalgae colonizes equipment rapidly leading to natural color and texture
(See Appendix B – Photos for examples).
3.3.1 View Obstruction
View obstruction is related to the degree of obstruction in viewing the farm by vegetation,
landform, or man-made objects.
3.3.1.1 View Obstruction Rating
Individual Element Rating: Moderate – Partially obstructed view
15 to 20 homes have unobstructed view of the proposed geoduck planting area. During the site
visit, nearby trees were in the leaf-off condition. The estimate of 15-20 homes with unobstructed
views will be reduced during the summer when trees have a cover of leaves that are likely to more
fully block views.

3.3.2 Distance Offshore/Observer Position
Visibility is critically related to the distance the farm is located from observation points and the
height of key observation points above sea level.
3.3.2.1 Distance Offshore/Observer Position Rating
Individual Element Rating: Low – Areas with little visibility
This element is rated low because distance from most potential viewers (i.e. visible residences and
Shine road) to aquaculture is greater than 1500 feet and between 20 feet and 50 feet above sea level.
3.3.3 Viewshed Coverage
Viewshed coverage is related to the percentage of the normal cone of vision occupied by the
proposed aquaculture facility.
3.3.3.1 Viewshed Coverage Rating
Individual Element Rating: Low
The proposed geoduck planting area covers less than 5% of the cone of vision when viewed from
nearby residences. The project is only 500 feet wide along the nearly 2-mile-long northern
shoreline of Squamish Harbor.
3.4 Extent of Probable Visual Impact
Scores from the inventory of scenic quality, sensitivity level, and visibility are incorporated into an
overall score to determine the severity of the probable visual impact.
Scenic Quality Summary Category Rating: Moderate
Sensitivity Level Summary Category Rating: Moderate
Visibility Summary Category Rating: Low

Using the matrix provided in the Visual Assessment Workbook to determine the extent of visual
impact of the project site leads to a Class IV Low Visual Impact. This determination is based on the
fact that the site is visible only a small portion of the time, the site is not visible from heavily
traveled routes, the surroundings are heavily altered by local residential development, and the
PVC geoduck tubes will quickly take on a natural color due to colonization by aquatic flora and
fauna (see photo 13 in Appendix B). Based on the resultant Class IV Low Visual Impact rating, the
project should require no mitigation measures to reduce visual effects.
