Executive Summary
Soundview Consultants LLC has been hired by HHJ Architects, PLLC and the Port of Grapeview
(Applicants) to provide a Shoreline and Critical Areas Assessment, Federal Emergency Management
Agency (FEMA) Floodplain Assessment and Endangered Species Act (ESA) Assessment, and
Habitat Management Plan for a 164-linear foot floating community dock with an access gangway
and sidewalk on an approximately 0.44-acre parcel located at Grapeview Loop Road and Griswold
Avenue in Grapeview, unincorporated Mason County, Washington (subject property). The subject
property is situated in the Southwest 1/4 of Section 5, Township 21 North, Range 01 West, W.M.
(Mason County Tax Parcel Number 12105-51-00900).
Soundview Consultants LLC investigated the subject property for wetlands,waterbodies, potentially
regulated fish and wildlife habitat, and/or priority species in the spring of 2017. Site investigation
identified the shoreline of Case Inlet, Puget Sound and a FEMA mapped flood zone along the
shoreline. A flood zone habitat assessment and mitigation plan is necessary to ensure the project
avoids, minimizes and/or compensates for impacts to the flood zone. No other streams, wetland,
drainages or sensitive Fish and Wildlife habitats or species were identified during site investigation.
The Washington Department of Fish and Wildlife (WDFW) has identified estuarine/marine aquatic
habitat in the vicinity of this shoreline area (Appendix 134). WDFW SalmonScape data does not
identify any priority species at the site's shoreline or any nearby tributaries with fish presence. The
marine shoreline is likely regulated by the U.S. Army Corps of Engineers (USACE), Washington
State Department of Ecology (WSDOE),and Mason County.
Impacts of a new overwater structure will be mitigated by avoiding and minimizing impacts to the
extent practicable. The overwater portions of the elevated and floating dock sections will be at
least 50% grated, to allow light to penetrate to the water. The joint use community dock will
minimize the need for additional individual or joint use docks for water access in the vicinity of the
Fair Harbor Marina. Unavoidable impacts will be compensated by restoring currently disrupted
intertidal shoreline habitat.
Regulatory requirements for the proposed community dock were carefully considered and identified
under Mason County Code (MCC) 17.50—Shoreline Master Program Use and Regulations and Title
8—Environmental Policy. Additionally, the subject property is within a 100-year flood zone,which
is regulated under MCC 14.22 — Flood Damage Prevention and 17.50.060 — Flood Protection and
Shoreline Stabilization. The marine shoreline is also likely regulated by the U.S. Army Corps of
Engineers (USACE) and Washington State Department of Ecology (WDOE).

Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
2.2 Purpose and Need
The proposed project will provide the community with a floating dock that provides public water
access and temporary moorage for individual and commercial users that will be launching boats at
the Port of Grapeview public boat ramp. The floating dock is not intended for overnight moorage
as it will bottom out at low tides, due to the bathymetry of this narrow channel; it will provide a
short term, temporary facility for boaters to moor while awaiting their turn to take out their boat or
to park their vehicle after launching.
2.3 Project Description
The proposed project is to construct a new 165-linear foot community dock consisting of a 48-foot
by 5-foot gangway and a 121-foot by 8-foot floating dock. The floating dock will consist of six (6),
20-foot by 8-foot pre-fabricated fiberglass sections with more than 50% grating. Each float section
will be supported by a 10-inch diameter steel pile.The waterward end of the dock will reach-4.3 feet
in elevation with the furthest waterward steel pile placed at -4 feet. A 48-foot by 5-foot grated
aluminum gangway with metal railings will be attached to the floating dock and supported by one
(1), 10-inch steel pile. A total of seven (7) piles are proposed for the entire dock. An 8-foot wide
section of the existing concrete bulkhead located at Ordinary High Water (OHW) will be replaced
with a new concrete wall section and footing (the "platform bulkhead"). Immediately landward of
OHW and the new bulkhead section, the gangway will connect to a new 8-foot by 8-foot, ADA
compliant, concrete platform with underground supports and wood railings. This platform will
connect further landward to a new 128-square foot concrete sidewalk,which will provide pedestrian
access (including ADA) from Griswold Avenue.
2.4 Construction Techniques
All pilings will be installed from the water, with a vibratory hammer mounted on a barge. Six (6),
prefabricated 20-foot by 8-foot floats with fiberglass grating will be floated in, connected, and
attached to the pilings after they are set in their final position. The landward end of the aluminum
gangway will attach, at OHW, to the pier platform. The waterward end will attach to the floating
dock. Installation of in-water elements will occur from a floating barge,during high tide.
Approximately 19 cubic yards of native soil/sediment will be removed immediately landward of
OHW to construct the pier foundation. Three concrete walls with footings will be poured in place;
one will be at the existing bulkhead (at OHW), and will replace the existing bulkhead (see section A
of sheet AP2.3). Two additional walls with footings will be poured perpendicular to the new
platform bulkhead. These three walls will form the foundation for the new pier platform. This will
be backfilled with clean, free draining, compacted gravel or CSBC (Crushed Surface Base Course),
and capped with compacted CSBC and a 4-inch thick concrete surface. The new ADA compliant
sidewalk will be poured in place concrete,over a prepared bed.
Best management practices (BMP) include the following:
1. Construction of over-water elements and installation of the piles will occur from a barge and
so will be completed during high tides. No grounding of the barge will be allowed. The
contractor will be required to submit a Construction/Tides Plan outlining possible work
dates and times that allow construction during the most desirable tidal period.
1267.0004-Port of Grapeview Dock 3 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
2. A coir log barrier shall be placed around the perimeter of the upland work area to prevent
sediments and debris from migrating waterward. This will be removed when the work is
completed or when the tide is flooding.
3. Work below OHW will only occur from January 1 through March 14 and July 1 through
December 31 of any consecutive year (i.e. a non-work window exists from March 15 and
June 30 for the protection of migrating salmonids potentially in the project vicinity during
that period).
4. The contractor shall develop and implement a site-specific spill prevention,containment and
control plan (SPCCP).
5. The movement and use of heavy or tracked machinery is restricted to the staging area.
6. Beach area grades disturbed during construction will be reshaped to pre-project conditions
upon project completion.
7. All construction equipment will be inspected daily for fluid leaks and no equipment will
leave the staging area until any leaks are repaired.
8. Fueling and maintenance of equipment will occur in upland staging areas only.
9. No excavated materials will be stockpiled below the OHW mark.
10.No materials shall be stockpiled outside of the staging area unless they will be used in that
day's work.
2.5 Action Area
The "Action Area" encompasses the locations where project activities will occur (the Project Area),
plus areas that may be directly or indirectly affected by the proposed project either through physical,
chemical, or biological mechanisms. The geographic limits of the Action Area were defined by
considering the potential spatial extent of mechanisms that may lead to impacts on listed species.
Mechanisms identified as having potential for impacting ESA-listed species or species habitat
include noise from construction equipment and a potential increase in turbidity from sediment in-
water suspension caused by construction activities. The Action Area for these potential impact
mechanisms is depicted in Appendix D.
2.5.1 Calculating Terrestrial Noise Attenuation
Calculations for the distance to terrestrial noise attenuation to ambient levels were conducted using
WSDOT Biological Assessment preparation methods (WSDOT, 2015). Terrestrial construction
noise sources will consist of a vibratory pile driver, an excavator, and a concrete pump truck.
Vibratory pile drivers are estimated to have a terrestrial noise level of 101 dB at 50 feet,and both an
excavator and concrete pump truck have a noise level of 81 dB per Table 7-4 of the WSDOT
Guidance (WSDOT,2015). Using decibel addition,it was determined that the combined noise level
of all construction equipment is 101 dB. The normal attenuation rate of 6 dB per doubling distance
for a hard site was applied to provide a conservative estimate because the site is adjacent to water,
residential areas, and a main road (East Grapeview Loop Road) that are considered reflective
surfaces that do not provide much attenuation.
Using 101 dB as the noise impact level along with an ambient level of 61 dB (WSDOT, 2015)
considering the noise level for traffic volume for East Grapeview Loop Road that has a speed limit
of 40 miles per hour (mph) and a likely traffic volume (vehicles/hour) of 250, the following table
and graph present the estimated construction noise attenuation distance. This analysis results in
attenuation to ambient noise levels at 5,000 feet from the Project Area, which is demonstrated in
Table 1 and graphically depicted in Figure 2. From the table and trend line equation on the chart an
1267.0004-Port of Grapeview Dock 4 Soundview Consultants LLC

estimated perimeter for the terrestrial action area would denoted by a radius of 5,482 feet beyond
the Project Area.

2.5.2 Calculating In-Water Noise Attenuation
To minimize in-water impacts, only vibratory pile driving methods will be used for in-water pile
installation and only seven, 10-inch in diameter pile will be used. To determine the Action Area
impacted by the sound from the vibratory hammer, an in-water sound area model was created. The
aquatic sound Action Area occurs in Case Inlet, South Puget Sound,where it is constrained by land
1267.0004-Port of Grapeview Dock 5 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
masses on all sides. Calculations were conducted using noise methods outlined in the WSDOT
Biological Assessment preparation manual (WSDOT,2015).
In-water construction will consist of vibratory pile driving of seven, 10-inch diameter steel pile.
Using WSDOT Biological Assessment preparation methods,vibratory pile drivers emit sound levels
10-20 dB below that of impact pile drivers. The WSDOT guidance document, for a 12-inch steel
pile,recommends a value of 173 dB (RMS) at a distance of 10 meters (32.81 feet) for a vibratory pile
driver. This is used here as conservative comparison, as the guidance does not provide noise
estimates for driving 10-inch pile using vibratory pile driving methods. WSDOT guidance suggests
that background sound levels be compared to that of previous WSDOT noise analysis studies within
the Puget Sound. The ambient underwater noise level for the project site will be estimated using the
ambient underwater noise level for a site on Vashon Island,which has an underwater noise level of
128 dB.
Applying the normal attenuation rate of 4.5 dBA per underwater doubling distance results in an
attenuation line as demonstrated below in Table 2 and displayed in Figure 3. From the table, the
calculated perimeter for the in-water Action Area would extend to approximately 33,592 feet (6.4
miles); however, the underwater noise will reach land on all sides prior to this calculated distance.
The underwater noise Action Area would be constrained by land rather than attenuated in all
directions to a maximum distance of approximately 12,000 feet (2.3 miles) to the northeast, just
north of Rocky Bay.

2.5.3 Turbidity
The proposed construction activities may incidentally suspend sediment materials in the marine
waters adjacent to the project site. Such occurrences, if at all, would be temporary in duration. To
avoid or minimize potential temporary increases in turbidity, all appropriate temporary erosion and
sediment control (TESC) measures and construction best management practices (BMPs) will be
implemented.
The Washington Administrative Code (WAC 173-201A-210(1)(e)) makes allowances for temporary
turbidity in marine waters due to construction activities. Temporary mixing is subject to constraints
of WAC 173-201A-400(4) and (6). A 150-foot plume limit is being included in the Action Area to
account for possible temporary increases in turbidity. Any turbidity impacts are expected to be
temporary due to the conservation measures and BMPs that will be in place for the project, and will
comply with WAC 173-201A-400(4) and (6).

Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
Chapter 3. Methods
SVC investigated and assessed shoreline conditions and potentially-regulated wetlands, waterbodies,
and other fish and wildlife habitat within the subject property and identified critical areas within 250
feet of the subject property, according to the standards set forth in Mason County Code (MCC)
Title 8.52.
In January, April, and June of 2017, qualified SVC staff conducted onsite assessments. All
determinations were made using observable vegetation,hydrology,and soils in conjunction with data
collected from the U.S. Geographic Survey (USGS) topographic map, the Natural Resources
Conservation Service (MRCS) Soil Survey, National Wetlands Inventory (NWI), U.S. Fish and
Wildlife Service (USFWS), Washington Department of Fish and Wildlife (WDFW), Department of
Natural Resources (DNR), Washington Department of Ecology (WSDOE), Mason County
Geographic Information Systems (GIS), local precipitation data (NOAA), and various
orthophotographic resources. Appendix A contains further details for the methods and tools used
to prepare this report.
Wetland presence/absence was determined in accordance with MCC 8.52.110,and as outlined in the
U.S. Army Corps of Engineers'Wetlands Delineation Manual (Environmental Laboratory, 1987) as
modified according to the guidelines established in the Regional Supplement to the Corps of
Engineers Wetland Delineation Manual: Western Mountains,Valleys,and Coast Region,Version 2.0
(USACE,2010).
The fish and wildlife habitat assessment was conducted during the same site visits by qualified fish
and wildlife biologists. Experienced biologists made visual observations using stationary and
walking survey methods for both aquatic and upland habitats noting any special habitat features or
signs of fish and wildlife activity.
A low tide beach survey for submerged aquatic vegetation and other aquatic organisms and features
was completed on May 27, 2017, per WDFW guidance, entitled Eelgrass/Macroalgae Habitat
Interim Survey Guidelines (06/16/2008) (Appendix F).
The OHW mark was made using the Washington State Department of Ecology's (Ecology) method
detailed in Anderson, P.S., S. Meyer, P. Olson, and E. Stockdale, 2016, Determining the Ordinary High
Water Mark for Shoreline Management Act Compliance in Washington State (Anderson, P.S., et al.) and the
definitions established in the Shoreline Management Act (Revised Code of Washington [RCW]
90.58.030(2)(b) and Washington Administrative Code (WAC) 173-22-030(11)).

Chapter 4. Existing Conditions
4.1 Landscape Setting
The subject property is in an urban residential setting, in unincorporated Mason County and
includes approximately 28 linear feet of nearly horizontal marine shoreline located along Case Inlet
of Puget Sound. A community concrete ramp is currently on the subject property shoreline
extending out into Case Inlet and encumbering portions of the south adjoining property. Existing
upland features include a paved access road (Griswold Avenue) to the existing ramp. The shoreline
consists of a coarse pebble substrate in the upper intertidal zone transitioning to very coarse, rocky
substrate in the lower intertidal zone. Quarry spalls have been placed on the shoreline on the north
of the existing concrete ramp. The intertidal area shows signs of sorting and shifting of finer
substrate, suggesting there is a moderate degree of tidal energy being exerted. The shoreline is
moderately populated with small mollusks and other macroinvertebrates (red rock crab, ghost
shrimp, mud snail, moon snail). Sea lettuce (Ulva sp) was observed attached to and growing within
the beach substrate, but the shoreline lacks any significant rooted, vascular plant species. Adjacent
properties to the north are developed with single-family residences, to the east by Case Inlet, to the
south by Fair Harbor Marina and associated structures, which provides boat moorage for
recreational boaters, fuel for motorized boats and grocery/gift shopping, and to the west by East
Grapeview Loop Road. The adjoining properties that abut Case Inlet to the north and south
contain hardened shorelines encumbered by concrete bulkheads with upland vegetation consisting
predominantly of ornamental grass with some ornamental trees and shrubs. A storm drainage pipe
extends out from the north adjoining concrete bulkhead, just north of the existing ramp with water
draining out onto the surface of the shoreline and into Case Inlet.
Topography on the upland is approximately 20 feet above mean sea level (amsl) with a gentle slope
to the east toward Case Inlet. A topographic map is provided in Appendix B1.
4.2 Soils
The Natural Resource Conservation Service identified one soil series on the subject property,
Alderwood gravelly sandy loam, 8 to 15 percent slopes. This soil formed in ridges and hills with a
parent material consisting of glacial drift and/or glacial outwash over dense glaciomarine deposits.
In a typical profile, the surface consists of gravelly sandy loam from 0 to 7 inches below ground
surface (bgs). The subsurface consists of very gravelly sandy loam from 7 to 59 inches bgs. A soil
map is provided in Appendix B2.
4.3 Vegetation
Upland portions of the subject property do not contain any vegetation, as it consists primarily of a
paved road (Griswold Avenue). Shoreline areas at the subject property lack any significant rooted,
vascular plant species although there is a small patch of salt tolerant emergent vegetation in the
vicinity of the stormwater outfall: an area measuring approximately 30 square feet contains small
clumps of pickleweed (Salicornia tirginica) and seaside plantain (Plantago maritima). Several species of
marine algae were observed including sea lettuce (Ulna sp) and red algae (Odonthalia floccose).

4.4 Hydrology
4.4.1 Streams and Wetlands
The Mason County Streams and Wetlands map and the USFWS NWI map identifies estuarine and
marine wetlands within Case Inlet adjacent to the site (Appendix's B3 and B4); however, the site
investigation did not observe such habitats. The DNR Stream Typing map and WDFW
SalmonScape map did not identify any potentially regulated streams within the subject property or
vicinity (Appendix's B5 and B6).
4.4.2 FEMA Mapped Flood Area
The Mason County Flood Zone map indicates that a portion of the project is within a special flood
hazard area, subject to inundation by the 1% annual chance of flood (100-year flood). A Mason
County Flood Zone map is provided in Appendix B7.
4.5 Priority Habitat and Species
The WDFW Priority Habitat and Species (PHS) map and data identify the potential for estuarine
and marine wetlands and a purple martin breeding area. One purple martin breeding area location
was identified at the Fair Harbor Marina, which is the south adjoining property and is listed with a
candidate status, which is not identified as endangered, threatened, or sensitive. For management
recommendations for the purple martin, the PHS map and data has a link that will direct to habitat
management documentation written by WDFW(Appendix B8). WDFW Forage Fish and Spawning
map and SalmonScape map did not identify any fish species or spawning areas within the subject
property or vicinity (Appendix B6 and B9). The WSDOE Shoreline Biology map identified patchy
eelgrass fringes, patchy salt marsh fringes, and patchy low marsh fringes on the shoreline of the
subject property (Appendix B10). The site investigations did not indicate any estuarine and marine
wetlands or any significant plant species within the shoreline area of the subject property.

Chapter 5. Case Inlet Shoreline
The subject property abuts approximately 28 linear feet of the marine shoreline of Case Inlet within
Puget Sound. The shoreline environment for this area is designated by Mason County as Urban
Residential, with requirements found under MCC Title 17.50.074. Although background
information (Appendix B-4- NWI Map and Appendix B10—WSDOE Shoreline Biology Map)
indicates estuarine and marine wetlands, patchy eelgrass fringes, patchy salt marsh fringes, and
patchy low marsh fringes located within the shoreline at the subject property, the site investigations
did not observe such habitats. The shoreline at the subject property consists of a coarse pebble
substrate in the upper intertidal zone transitioning to very coarse, rocky substrate in the lower
intertidal zone. The intertidal area shows signs of sorting and shifting of finer substrate, suggesting
there is a moderate degree of tidal energy being exerted. The shoreline is moderately populated with
small mollusks and other macroinvertebrates,but lacks any significant rooted,vascular plant species.
Several species of marine algae were observed including sea lettuce (Ulva sp) and red algae
(Odonthalia floccose). The subject property has been used as a community ramp extending out into
Case Inlet for at least 60 years. Case Inlet is used as a boat thruway with Fair Harbor Marina located
on the south adjoining property. Such uses of Case Inlet have caused significant degradation to
ecological functions within the shoreline of the subject property and surrounding areas. No priority
species or potential spawning habitat for forage fish (sand lance, surf smelt, and Pacific herring) is
identified in the project vicinity. Table 3 provides a detailed summary of the shoreline at the site.

Chapter 6. Regulatory Considerations and FEMA
Analysis
The site investigation identified the shoreline of Case Inlet within Puget Sound on the subject
property. The project proposes to develop a new 165-linear foot dock. Regulatory requirements
within Mason County Code (MCC) Title 17.50 — Shoreline Master Program Use Regulations and
MCC Title 8 — Environmental Policy were considered with respect to the proposal. Additionally,
the subject property is within a 100-year flood zone, which is regulated under MCC 14.22 — Flood
Damage Prevention and 17.50.060 — Flood Protection and Shoreline Stabilization. The marine
shoreline is also regulated by USACE and WSDOE.
6.1 Mitigation Sequencing
MCC 8.52.170 requires that a sequence of actions be taken for proposals that have the potential to
impact shorelines. Projects should first attempt to avoid impacts altogether by not taking certain
actions. If a project cannot eliminate those actions, then the project should reduce impacts by
limiting the degree of the action, using different technology or by taking steps to minimize impacts.
For impacts that cannot be avoided or reduced, projects should propose measures for rectifying and
minimizing the adverse impacts through compensation by replacing, enhancing, or providing
substitute resources or environments. Mitigation actions should also be monitored and appropriate
corrective measures taken. The sections below describe the mitigation sequencing steps conducted
for this project.
Avoidance
The proposed dock is a water-dependent use consisting of an overwater structure, for which impacts
cannot be avoided. As a result, reduction and compensation measures will be implemented to
minimize impacts caused by the proposed project.
Minimization
To reduce potential long-term impacts to shoreline functions, the gangway and floating dock
sections will by grated to allow sunlight to penetrate to the surface water and shoreline bed under
the structure. The number (7) and diameter (10-inches) of piles are the minimum necessary to
support the gangway and floats. The piles will be steel rather than creosoted or treated wood, and
they will be driven by vibratory, rather than impact hammer. Furthermore, because the proposed
dock is a community-use dock,it will likely reduce the need for individual and joint-use docks in the
area.
Compensation
To compensate for the unavoidable impacts to shoreline habitat, drift logs will be installed and
anchored south of the boat ramp, in an area measuring approximately 1,600 square feet. Native
shoreline vegetation will be installed among the drift logs. In addition, approximately 200 square
feet of the upper shoreline (landward of OHW) will be planted with native shore-friendly shrubs and
emergent plants. The removal of the existing angular rock (approximately 1,538 square feet) will
restore the beach substrate to natural conditions that will be better able to support marine
macroinvertebrates and migrating fishes.

Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
6.2 Regulated Shoreline
The shoreline environment for the subject property and surrounding area is designated Urban
Residential under MCC 17.50.074. Docks are regulated under MCC 17.50.060,which indicates that
a recreational community dock length may not exceed the lesser of 15 percent of the fetch or 115
feet from the OHW mark and will not exceed a depth of-5 feet as measured at the mean lower low
water (MLLW) mark. The width of the dock will not exceed 8 feet.
Floating structures will be a minimum of 8 inches above the surface of the water and will include
intermittent supports to keep structures off the tidelands at low tide. Community use docks may be
permitted on the property line without a side yard setback. Recreational development under MCC
17.50.060 requires that recreational facilities will make adequate provisions, such as screening, buffer
strips, fences, and signs, to prevent overflow and to protect the value and enjoyment of adjacent or
nearby private properties. All permanent recreational structures and facilities will be located outside
officially mapped floodways; however, the county may grant exceptions for non-intensive accessory
uses. The shoreline at the site is regulated under MCC Title 17.50. Pursuant to MCC 17.50.060 -
Use Regulations and the Case Activity Listing issued by Mason County, commercial development at
the site requires a 5-foot side-yard setback beginning at OHW and extending into upland areas.
The project proposes a dock that is 8 feet wide but that would extend 165-linear, exceeding the
maximum length allowed for a community dock by approximately 45 feet. To achieve reasonable
use at the community dock, the dock must be long enough to reach water levels deep enough to
sustain a docked boat for a sufficient period of time. According to a topographic survey conducted
at the subject property, the dock will need to be extended out to 165-linear feet from OHW in order
to reach a depth of-4.3 feet (HHJ Architects PLLC 2017). The dock will still completely ground
during the lowest of tides, but this length of dock will provide reasonable (temporary) moorage
opportunities while not extending out so far as to impact navigation or to extend beyond that
afforded neighboring docks (at Fair Harbor Marina to the south). A Shoreline Variance will be
necessary to grant relief from the dimensional standards set forth in the shoreline master program
(MCC 17.50.090).
The proposed dock will require a Shoreline Substantial Development Permit and a Shoreline
Variance. According to MCC 8.52.170, granting of a Mason County Environmental Permit is
predicated upon the project incorporating measures to mitigate and compensate for impacts through
a Habitat Management Plan. Additionally, a SEPA determination, a Hydraulic Project Approval,
and Federal Clean Water Act(CWA),Sections 10 and 404 permits will be required.
WSDOE documented a leaking underground storage tank (LUST) on the south adjoining property
at Fair Harbor Marina and approximately 80 feet southwest of the proposed dock (Cleanup Site ID
6309, per WSDOE's online Cleanup Site Search). The LUST was first identified with leaking 200
gallons of diesel fuel and contaminating soils in 1990. The fuel was reported to have migrated to an
eastern retaining wall in a 4-foot by 4.5-foot area where bioremediation took place. In 1992,
approximately 75 cubic yards of contaminated soil was removed after a 2,000-gallon underground
storage tank (UST) was removed. Soil and groundwater samples were collected after the
contaminated soil excavation and all contaminants were below detection levels. In 2007, a
subsurface investigation conducted by Sound Environmental Strategies reported the historic
removal of two 1,000-gallon USTs and one current 4,000-gallon UST containing gasoline. Seven
soil samples were collected up to a depth of 16 feet bgs. Contaminants within the soil samples were
1267.0004-Port of Grapeview Dock 14 Soundview•Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
identified below clean-up levels. Groundwater was collected; however, an insufficient quantity was
collected. In 2008,WSDOE changed the site status to "Reported Cleaned Up".
A previous SEPA determination for the installation of a ramp at the subject property raised concern
about the potential to disturb any potential contaminated soils from the past LUST at Fair Harbor
Marina (south adjoining property). Best Management Practices (BMPs) regarding special handling
with regards to the previous LUST were recommended. These BMPs are addressed in the mitigation
section of this report (see Chapter 9).
Bedland below Mean Low Water (MI..W) is owned by the Washington State Department of Natural
Resources (DNR). The proposed dock will encroach over DNR bedlands and will require an
Aquatic Lands Lease.
6.3 FEMA Analysis
The shoreline at the subject property consists of coarse pebble substrate in the upper intertidal zone
transitioning to very coarse, rocky substrate in the lower intertidal zone. Quarry spalls are upon the
shoreline, directly adjacent to the existing concrete ramp to the north and south. Adjoining
shoreline areas contain hardened shorelines encumbered by concrete bulkheads. A portion of the
subject property is described as a frequently flooded area per MCC 8.52.130 (Appendix B7), and
because development of the proposed dock is below the base flood elevation, a floodplain
development permit is required before construction begins within any area of special flood hazard
areas. Under provisions for flood hazard reduction, all new construction will be anchored and
constructed using methods and practices that minimize flood damage (MCC 14.22.160). According
to MCC 8.52.170, permits will only be granted if the project takes appropriate measures to mitigate
and compensate for impacts through a Habitat Management Plan.
The proposed project will not have an adverse effect upon shoreline resources and uses at the
subject property or any adjoining properties. The proposed project will not result in increased flood
heights,additional threats to public safety,extraordinary public expense,or create any nuisances.

Chapter 8. Project Effects on ESA-Listed Species
This chapter includes an analysis of project affects to ESA-listed species that have potential for
presence in the project action area. The species assessed include marbled murrelet, humpback
whale, steelhead trout (Puget Sound distinct population segment), chinook salmon (Puget Sound
evolutionary significant unit), killer whale (southern resident distinct population segment),bull trout,
bocaccio rockfish,and yelloweye rockfish.
Potential project impacts are evaluated based upon specific habitat components that would be
altered or removed and the degree to which such alteration may occur; the abundance and
distribution of the habitat components; the distribution and population levels of the species (if
known); the possibility of direct or indirect impacts to the species and/or habitat, and the potential
to mitigate for adverse effects. These determinations are summarized in Table 5.

8.1 Direct and Short-Term Effects
The proposed project actions have three mechanisms for direct and short-term impacts to the
Action Area: temporary increases in terrestrial and underwater noise and a potential increase in
turbidity from in-water suspension of sediment from construction activities (primarily pile driving).
1267.0004-Port of Gnpeview Dock 17 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
BMP's will be utilized during construction actions, including installation and maintenance of silt
fencing, controlling sediment movement out of construction accesses, and covering disturbed soils
when not being worked. Noise from construction activities could directly impact terrestrial and
aquatic ESA-listed species if present.
8.2 Short-Term Effects
8.2.1 Sound
As previously discussed in Section 2.5.1, impacts to the local environment from project noise may
occur within a 5,000-foot terrestrial radius of the Project Area. The estimated sound level from the
use of project machinery is higher than the estimated ambient sound level for the traffic volume
from East Grapeview Loop Road. Noise from project activities can adversely affect wildlife with
various behavioral and/or health-related consequences (WSDOT, 2015). Sounds affect marine
species differently. Pulse noise, such as impact pile driving, has a greater likelihood of affecting fish
behavior when compared to continuous noise. Vibratory hammers produce noise levels that are
typically 10-20 dB less than an impact hammer(WSDOT,2015).
The ambient underwater noise level for the project site is estimated using the ambient underwater
noise level for a site on Vashon Island, which has a background underwater noise level of 128 dB.
As previously discussed in Section 2.5.2, the underwater construction noise will attenuate at 33,592
feet (6.4 miles); however, the underwater noise will reach land on all sides prior to this calculated
distance. The underwater noise Action Area would be constrained by land rather than attenuated in
all directions to a maximum distance of approximately 12,000 feet (2.3 miles) to the northeast, just
north of Rocky Bay.
Per WSDOT's 2015 Biological Assessment preparation guidance, the current threshold for fish
injury is 206 dB peak. The threshold for impacting fish behavior is 150 dB RMS (Root Mean
Square); for cetaceans and pinnipeds, vibratory pile driving methods can disturb individuals at 120
dB RMS. The WSDOT underwater sound impacts fish calculator is applicable to impact pile driving
strike peaks. This model is not applicable to this project as only vibratory pile driving methods will
be used for driving in-water pile. Noise for vibratory pile driving will not exceed the threshold for
injury to fish, cetaceans, or pinnipeds; however, if a fish or marine mammal is within the Action
Area during pile driving actions the species could be exposed sound levels that may impact behavior.
8.2.2 Turbidity
Increased turbidity due to pile driving activities is expected to be localized and temporary. The
proposed construction activities may incidentally suspend sediment materials in the marine waters
adjacent to the project site. WAC 173-201A-210(1)(e) makes allowances for temporary turbidity in
marine waters due to construction activities. Temporary mixing is subject to constraints of WAC
173-201A-400(4) and (6). A 150-foot plume limit is being included in the Action Area to account
for possible temporary increases in turbidity. Any turbidity impacts are expected to be temporary
due to the conservation measures and BMPs that will be in place for the project, and will comply
with WAC 173-201A-400(4) and (6).

Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
8.3 Long-Term Effects
The project is located on a portion of a parcel that is approximately 0.44-acres in size and located on
the shoreline of Case Inlet in Puget Sound. The overall effect will involve the installation of seven,
10-inch steel pile, permanently displacing 12.36 square feet of upper intertidal beach substrate and
approximately 483 square feet of new overwater shading from the 48-foot by 5-foot gangway and
121-foot by 8-foot dock, both with 60 percent grated surfaces in the upper intertidal shoreline. No
other long-term impacts to species or species habitat are anticipated.
8.4 Determinations of Effect
8.4.1 Critical Habitat
Critical Habitat is defined as: (1) The specific areas within the geographical area occupied by the
species, at the time it is listed in accordance with the Act, on which are found those physical or
biological features (a) essential to the conservation of the species and (b) which may require special
management considerations or protection, and (2) Specific areas outside the geographical area
occupied by the species at the time it is listed, upon a determination such areas are essential for the
conservation of the species. Critical Habitat for a listed species contains Primary Constituent
Elements (PCEs),as defined below.
8.4.2 Primary Constituent Elements
In accordance with Section 3(5)(A)(i) of the ESA,and regulations at 50 CFR 424.12(b),to determine
which were areas occupied at the time of listing (for Critical Habitat designation), we consider the
physical or biological features (known as the PCEs) essential to the conservation of the species and
that may require special management considerations or protection. These include, but are not
limited to: (1) space for individual and population growth for normal behavior; (2) food, water, air,
light, minerals, or other nutritional or physiological requirements; (3) cover or shelter; (4) sites for
breeding, reproduction, or rearing(or development) of offspring; and (5) habitats that are protected
from disturbance or are representative of the historical,geographical, and ecological distributions of
a species.
8.4.3 Species Determinations
The Action Area is in Tidal Reference Area 2 (Olympia) in Case Inlet. The work window for
salmon is July 2-March 2 and Bull trout is July 16—February 15. The work window for all fish is July
16 through February 15. Construction of all project elements will occur within that window—
between July 16 and February 15 of any consecutive years. The following ESA-listed species may
experience project effects as described below.
Marbled Munelet and Marbled Murrelet Critical Habitat
Brachyrhampus marmoratus—Threatened,listed 1992
Critical Habitat designated May 1996(SO CFR Part 17.11)
Marbled murrelet are members of the Alcidae family of seabirds, which includes puffins, murres,
and auklets. In the state of Washington, they are year-round residents on coastal waters. They
primarily feed in waters within 500 feet of the shore out to 1.2 miles from shore, at depths of less
than one hundred feet. Preferred prey includes small fish and crustaceans. Nestlings may be fed
larger fish. Nests and roosts are found in mature and old growth forests of western Washington.
1267.0004-Port of Grapeview Dock 19 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
Nest trees are typically greater than thirty-two inches diameter at breast height, with nesting
preference on large flat conifer branches, often covered with moss (WDFW, 1991) and found in old
growth forests. Marbled murrelets have been found in the largest numbers in marine waters near
the coastal waters surrounding the Olympic Peninsula(Pearson and Lance,2010). Marbled murrelet
are more sparsely distributed elsewhere in this region. Prey species predominantly include the forage
fish sand lance, surf smelt, and Pacific herring. Critical habitat has been designated in Oregon and
California. USFWS, 2011, discusses Primary Constituent Elements of Critical Habitat for marbled
murrelets: (1) trees with potential nesting platforms and, (2) forested areas within '/2 mile of potential
nest trees with a canopy height of at least'/2 of the site potential tree height.
The Action Area contains no suitable nesting habitat for the marbled murrelet. Foraging habitat
may be found in the Puget Sound as marbled murrelet are opportunistic feeders. However,lack of
suitable habitat and the high level of human use of the Action Area make marbled murrelet presence
in the Action Area unlikely. Neither species presence nor supporting habitat is identified within the
subject property. The most likely presence of marbled murrelet would be from the species passing
over the Action Area en-route to foraging sites.
Noise resulting from project activities will be below precautionary harassment/injury guidelines for
ESA-listed species that may be present in the proposed project area. The estimated threshold of
harassment/injury for marbled murrelets is approximately 92 dBA at nest sites and at a nesting site
the disturbance threshold is an estimated 70 dBA (WSDOT,2015). Noise levels from the proposed
construction may be as high as 174 dBA at 107 feet from project activities but will attenuate to
background noise levels at 995,344 feet. The proposed actions May Affect, but are Not Likely to
Adversely Affect the Marbled Murrelet. No critical habitat or essential habitat elements are found
within the vicinity of the Action Area (USFWS, 2011); there will be No Effect on Marbled
Murrelet Critical Habitat.
Humpback Whale
Megapten novaeanglise—Endangered,listed June 2, 1970.
Humpback whales range from southern California, north through the Aleutian Islands while feeding
in the Pacific Ocean (NMFS, 1991). While humpback whales are more likely to remain in waters on
the outer coast during their migration, there have been several sightings within Puget Sound as
recently as May 27, 2017. However, due to the unlikelihood of humpback whales entering this far
into Case Inlet and the complete lack of suitable habitat in the vicinity of the Action Area, the
project will have No Effect on Humpback Whale.
Puget Sound Steelhead Trout
Oncotbynchus mykiss--Threatened,listed May 11,2007.
Critical habitat designated February 2016(81 FB9251).
Puget Sound steelhead trout are documented within Puget Sound. National Oceanic and
Atmospheric Administration (NOAA) Fisheries identified fifteen (15) Distinct Population Segments
PPS) of steelhead trout in Washington, Oregon, and California, divided into two (2) basic
reproductive ecotypes, based on the state of sexual maturity at the time of river entry (summer or
winter) and duration of spawning migration. Steelhead trout are iteroparous, meaning they can
spawn more than once. Steelhead trout can spend up to seven (7) years in freshwater prior to
smoltification (USACE, 2007). The Distinct Population Segment (DPS) in the Puget Sound
includes all naturally spawned anadromous winter-run and summer—run steelhead populations in
streams in the river basins of the Strait of Juan de Fuca,Puget Sound,and Hood Canal,Washington
1267.0004-Port of Grapeview Dock 20 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
bounded to the west by the Elwha River and to the north by the Nooksack River and Dakota Creek,
as well as the Green River natural and Hamma Hamma winter—run steelhead hatchery stocks.
Puget Sound Steelhead trout populations are considered "Depressed". Therefore, due to depressed
populations, the presence of steelhead trout in the Action Area during proposed project activities is
likely minimal.
Per WSDOT's 2014 Biological Assessment models, the current threshold for fish injury is 206 dB
peak. The threshold for impacting fish behavior is 150 dB RMS. Due to the lack of presence of
steelhead trout from depleted species and the proposal to complete all work during periods when
the project area is dry, the proposed project actions May Affect, but are Not Likely to Adversely
Affect Puget Sound Steelhead Trout.
Critical Habitat has been designated for Puget Sound steelhead trout as of February, 2016.
Ecological features that support steelhead trout habitat include (i) water quality and quantity
conditions and forage,including aquatic invertebrates and fishes, supporting growth and maturation,
and (ii) natural cover such as submerged and overhanging large wood,aquatic vegetation,large rocks
and boulders, and side channels. These habitat characteristics are not currently present at the
existing Port of Grapeview boat ramp and Fair Harbor Marina area. The proposed actions will have
No Effect on Critical Habitat for Puget Sound Steelhead Trout.
Puget Sound Chinook Salmon
Oncorh7ncbus tscbswytsba --Threatened,listed (reaffirmed)June 28,2005 (70FR37160).
Critical habitat designated September 2,2005(70FR52630).
Puget Sound Chinook Salmon are anadromous fish, meaning adults migrate from the ocean to
spawn in freshwater lakes and streams where their offspring hatch and rear prior to migrating back
to the ocean to forage until maturity. Fry and smolts will stay in freshwater environments for up to
eighteen (18) months before moving to downstream estuaries. They will spend up to one-hundred
and ninety days in estuaries before moving into ocean waters. Juvenile Chinook out-migrating from
outlying watersheds could also potentially use the Action Area from late March to mid July, as
indicated by sampling studies from the Tacoma Narrows and Commencement Bay.
Chinook salmon spend an average of three to four years in marine waters before returning to their
natal streams to spawn, which occurs in late summer to late fall. Their range is from Kotzebue
Sound,Alaska down to Santa Barbara, California. Many of the rivers located within their range are
used for Chinook spawning and rearing. Major runs can be found on the Columbia River, Rogue
River and within Puget Sound.
As juveniles, Chinook feed on insects, amphipods, and other crustaceans and will feed primarily on
other fish as adults. During early life stages mortality is high due to natural predation and
anthropogenic habitat changes including siltation, increases in water temperature, low oxygen, and
reduced stream flows. Fall Chinook populations in the Central and South Puget Sound regions are
primarily sustained through hatchery production (NMFS, 2012b). Indigenous populations have
diminished from habitat degradation, over-fishing, and the use of hatchery fish in the ecosystem.
Chinook are highly valued by the commercial fishery.
Due to the low likelihood of juvenile Chinook salmon in the Project Area during the proposed
actions,the ability of adults to avoid the area during the actions,the brief duration of sound impacts,
1267.0004-Port of Grapeview Dock 21 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
and the minimization measures, the proposed project actions May Affect, but are Not Likely to
Adversely Affect Puget Sound Chinook Salmon.
Turbidity is expected to be localized and temporary. The project effects are not likely to result in
any adverse effects to habitat for Chinook salmon. The proposed project actions May Affect, but
are Not Likely to Adversely Affect Puget Sound Chinook Salmon Critical Habitat.
Southern Resident Killer Whale—
Orcinus orca--Endangered,listed November 15,2005.
Critical Habitat designated November 2006.
Southern resident killer whale may be found in the Puget Sound or the Straits of Georgia and Juan
de Fuca during spring through fall. The website, www.orcanetwork.org, lists sightings near the
vicinity of the Action Area as "infrequent", however, killer whale may be found in South Puget
Sound from November through January and sightings have been reported in Carr Inlet as recently as
May 2017. A southern resident killer whale sighting compilation between 1990 and 2008 (Osborne,
2008) has compiled data regarding the average number of killer whale sightings per month over an
eighteen (18) year period. Due to unlikely presence of Southern Resident Killer Whales in the
Action Area, the short duration of sediment and noise impacts, and because turbidity is expected to
be localized and temporary, the proposed actions May Affect, but are Not Likely to Adversely
Affect Southern Resident Killer Whales.
Almost the entire Puget Sound has been designated as Critical Habitat for southern resident killer
whale, excluding areas that are less than twenty (20) feet deep during periods of high tide (NMFS,
2012a). Under the ESA "Critical habitat" is defined as: (1) specific areas within the geographical
area occupied by the species at the time of listing, if they contain physical or biological features
essential to conservation, and those features may require special management considerations or
protection; and (2) specific areas outside the geographical area occupied by the species if the agency
determines that the area itself is essential for conservation". It is unlikely that a southern resident
killer whale will enter this far north within Case Inlet or come this close to shore unless it is sick or
dying. Therefore, the proposed project May Affect, but is Not Likely to Adversely Affect
Southern Resident Killer Whale Critical Habitat.
Bull Trout
Salvelinus conBuentus--Threatened,listed November 1, 1999.
Critical Habitat designated October 2010 (75FR63898).
Bull trout are documented within Mason County, but have not been documented in any streams
within the Action Area. Moreover, bull trout are not known to use Puget Sound waters west of the
Nisqually Reach. Due to the lack of presence of bull trout in the action area, project actions will
have No Effect on Bull Trout.
Bocaccio Rockfish Sebastes paucispinis—listed Endangered July 27,2010;and
Yelloweye rockfish Sebastes entomelas—listed Threatened July 27,2010.
Presence of adult rockfish within the Action Area is unlikely as no habitat features are present to
attract these fish. Rockfish larvae are pelagic, often occupying the surface of open waters, under
floating algae, detached seagrass, and kelp. Juvenile bocaccio rockfish settle onto nearshore water
habitats with rocky or cobble substrate that support kelp growth at three (3) to six (6) months of
age, and move to progressively deeper waters as they grow (Love et al. 1991;Love et al. 2002). The
likelihood of juveniles or adults of ESA-listed rockfish within the relatively shallow and non-rocky
1267.0004-Port of Grapeview Dock 22 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
habitats of the project is discountable. Juvenile yelloweye rockfish do not typically occupy intertidal
waters and shallow habitats (Love et al. 1991). Adult bocaccio rockfish and yelloweye rockfish
typically occupy waters deeper than 120 feet (Love et al. 2002) and are unlikely to occur at the
project location.
Bocaccio rockfish have not been documented in the Puget Sound since 2001,although it is assumed
that an extant population exists (NMFS 2008a). Yelloweye rockfish are considered relatively rare in
the Puget Sound,observed more frequently in north Puget Sound than in southern areas (Miller and
Borton 1980). Juvenile rockfish recruitment is likely to be found in areas with shallow high —relief
zones with crevices and sponge gardens (Love et al 2002). Juveniles move from shallow rocky reefs
to deeper pinnacles and rocky habitats as they mature (NMFS 2008a). Adults are most common
between 300 to 600 feet water depth, sometimes associated with depths between 40 to 1,560 feet
deep (Love et al 2002). The existing substrate along the shoreline of the project is not ideal habitat
for rockfish recruitment and juvenile rearing which is typically associated with vegetated
(recruitment) and deeper hard substrate (rearing) high-relief deep-water habitat. The proposed
Project Area water quality conditions also likely limit the habitat suitability for juveniles. Deeper
portions of Puget Sound provide suitable habitat for adult and juvenile rockfish.
The limited potential for occurrence of rockfish within the Action Area may include drift larval and
small juvenile forms that could potentially be present within the Puget Sound waters during the
summer months. Any project effects to larval forms of rockfish are anticipated to be highly unlikely.
Due to lack of rockfish habitat features and minimal, temporary nature of sediment impacts
proposed, the proposed project May Affect, but is Not Likely to Adversely Affect these
Distinct Population Segments of Rockfish.
Several ESA- listed species listed in Tables 4 and 5 will not be found on or near the vicinity of the
Action Area. The proposed project is surrounded by moderately developed areas within a rural
residential area. Even though the species in Tables 4 and 5 may occur in Mason County,it is highly
unlikely that these animals will be found in the vicinity of the Action Area. The ESA-listed species
clearly not affected due to project location and surrounding environment conditions include,
streaked horned lark, yellow-billed cuckoo, Oregon spotted frog, Northern spotted owl, gray wolf,
Canada lynx,Taylor's checkerspot,leatherback sea turtle,and Mazama pocket gophers.
• The streaked horned lark (Eremophila a pestris strigata) is found primarily in prairie habitat or
unvegetated to sparsely-vegetated open habitats (WSDOT,2015). They can be found in
developed areas such as airports and agricultural lands. No habitat for this species is found
in the vicinity of the project;therefore,the project will have No Effect on Streaked
Horned Lark.
• Yellow-billed cuckoo (Coat'.Zus americanus) are migratory birds and historically ranged from
British Columbia to northern Mexico. Approximately 17 sightings in Washington have been
reported between 1956 and 2012, 13 of those sightings were east of the Cascades (WDFW,
2012). The yellow-billed cuckoo generally prefers riparian habitat of 50 acres or more
(WDFW,2012). Due to a lack of suitable habitat within the vicinity of the project area, the
project will have No Effect on Yellow-Billed Cuckoo.
• The Oregon spotted frog (Rana pretiosa) is endemic to the Pacific Northwest and spends the
majority of life in water. Often the Oregon spotted frog can be found in emergent wetlands
1267.0004-Port of Grapeview Dock 23 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
with willow, standing water. Warm, marshy areas are preferable, with an abundance of
emergent or floating vegetation, which is used for cover and forging (Watson, et.al. 2000).
As the Oregon spotted frog appears to be a freshwater species primarily associated with
wetland habitat and as no suitable habitat exists within the vicinity of the project area, the
project will have No Effect on Oregon Spotted Frog.
• Northern spotted owl (Strix occidentalis caurina) preferred habitat is found in mature
coniferous forests. Habitat for northern spotted owl was not identified within the subject
property (USFWS, 2008). It is more likely that Northern spotted owl would be encountered
within the North Cascades National Park where approximately 18,200 acres of habitat areas
for northern spotted owl habitat exist (University of Washington, 2006). No habitat for this
species is found in the Action Area;therefore,the project will have No Effect on Northern
Spotted Owl.
• Gray wolf (Canis lupus) generally inhabits temperate forests, mountains, tundra, taiga and
grassland environments. While they are somewhat habitat generalists, Gray Wolves do
require ungulate prey or other wild animals for scavenging. In addition, they require a large
amount of space (minimum of 10,000 to 13,000 square km)with low road density to support
a viable population (USFW, 2017). Because the Action Area and vicinity are highly
populated and densely urbanized areas, no habitat for the Gray Wolf exists in Action Area;
therefore,the project will have No Effect on Gray Wolf.
• The Canada lynx (Lynx Canadensis) in North America follows the distribution of boreal forest
ecosystems and ranges the south up into the subalpine forest of the western U.S. as well as
into the boreal/hardwood forests of the eastern U.S. Their populations persist in areas with
deep snow and have a large population of snowshoe hares, which is the main prey of the
lynx (USFW, 2017). No habitat for this species is found in the Action Area; therefore, the
project will have No Effect on Canada Lynx.
• The Taylor's checkerspot (Euphydryas editha taylorz) is found primarily in open prairie and
grass/oak woodland habitat (WSDOT, 2015). Taylor's checkerspot habitat is dependent
upon food sources for larvae and nectar sources for adults. No habitat for this species is
found in the vicinity of the project; therefore, the project will have No Effect on Taylor's
Checkerspot.
• Leatherback sea turtles (Dermochelys coriacea)are the most migratory and widely distributed of
all sea turtles,adult females require sandy beaches with vegetation and a short distance to dry
sand for nesting, and in general, the species prefer beaches that have close proximity to
rough seas and deep water. (USFW, 2017). Because the species is so migratory, critical
habitat has been designated in areas as far as the U.S. Virgin Islands, and has also been
designated along the shores in areas of California,Oregon and Washington,all the way up to
British Columbia but due to the urbanization of the area and lack of preferred habitat or
nesting beaches in the project area, their presence is highly unlikely; therefore, the project
will have No Effect on Leatherback Sea Turtle.
• Mazama pocket gophers (Thomomys maZama gladalis, Thomomys maZama pugetensis, Thomomys
maZama tumuli and Thomomys maZamayelmensis) require specific types of soils for their habitat.
1267.0004-Port of Grapeview Dock 24 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
These soils must allow them to tunnel into the ground and must be well-drained and easily-
crumbled. Soil types identified onsite by an NRCS survey identify Harstine gravelly sandy
loam and Hydraquents onsite,none of which are suitable soil types for Roy Prairie, Olympia,
Tenino and Yelm pocket gophers. In addition, the area surrounding the subject property is
fully developed and occupied by residential uses. Fragmentation of suitable habitat for
Mazama pocket gophers in historically occupied areas means that populations are not able to
move around easily, so even if suitable habitat existed onsite, it would be isolated and
surrounded by development; therefore, the project will have No Effect on Mazama
pocket gophers.

Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
Chapter 9. Conceptual Habitat Management Plan
This Habitat Management Plan assures that the proposed dock will not degrade the functions and
values of any associated critical areas.
Pursuant to MCC 8.52.170(g)(1), bank stabilization projects require a Habitat Management Plan
(HMP). MCC 8.52.1700) Habitat Management Plan Requirements states:
A HMP shall consider measures to preserve and protect the wildlife habitat and shall consider effects of land
use intensity, buffers, setbacks, impervious surfaces, erosion control and retention of natural vegetation on the
functions and values of the FWHCA. This report shall idenfifi, how the impacts from the proposed use or
activity will be avoided or mitigated through habitat mitigation which meets the purposes of this
chapter... For those projects requiring the preparation of a biological assessment (BA) or biological
evaluation (BE)as part of the application for a Corps of Engineers permit, the approved BA or BE meets
the requirements of a HMP.
9.1 Project Impacts
The proposed project could adversely affect Fish and Wildlife Habitat Conservation Areas or
Priority Species with direct and short-term actions: temporary increases in terrestrial and underwater
noise and a potential increase in turbidity from in-water suspension of sediment from construction
activities (primarily pile driving).
Long term adverse impacts could result from a new overwater structure shading a portion of the
intertidal zone and interfering with fish migration along the shoreline. The floating dock could also
impede natural sediment transport processes. The proposal will involve the installation of seven, 10-
inch steel pilings, permanently displacing 12.36 square feet of upper intertidal beach substrate and
approximately 483 square feet of new overwater shading from the 48-foot by 5-foot gangway and
121-foot by 8-foot dock,both with 60 percent grated surfaces in the upper intertidal shoreline.
9.2 Construction Sequencing and Best Management Practices
Most of the construction associated with this project shall occur landward of the OHW. Intertidal
work is limited to demolition of a section of the existing bulkhead and replacement with a new
platform bulkhead,and installation of seven (7) 10-inch diameter pilings. Bulkhead work shall occur
during low tides; installation of pilings will occur from a floating barge, during high tides.
Installation of the gangway and floating dock sections will be accomplished by floating in these pre-
fabricated elements and attaching them,while working from a floating barge.
The contractor will be required to submit a Construction/Tides Plan outlining possible work dates
and times that allow construction of all portions of the project during the applicable tide. It is
possible that some work may need to be conducted during the evening hours, as that is when low
tides occur during the proposed construction window.
A coir log barrier shall be placed around the perimeter of the work area to prevent sediments and
debris from migrating waterward. This will be removed when the work is completed or tide is
1267.0004-Port of Grapeview Dock 26 Soundview Consultants LLC
Shoreline,Critical Areas,FEMA and ESA Assessment Report and Habitat Management Plan June 29,2017
flooding. Work below the Ordinary High Water mark (OHW) shall only occur from January 1
through March 14 and July 1 through December 31 of any year. The contractor shall develop and
implement a site-specific spill prevention, containment and control plan. The movement and use of
heavy or tracked machinery is restricted to the staging area. Beach area grades disturbed during
construction will be reshaped to pre-project conditions upon project completion.
All construction equipment will be inspected daily for fluid leaks and no equipment will leave the
staging area until any leaks are repaired. Fueling and maintenance of equipment will occur in upland
staging areas only. If barge equipment is to be used, no grounding will be allowed. No excavated
materials will be stockpiled below ordinary high water (OHW). No materials shall be stockpiled
outside of the staging area unless they will be used in that day's work.
The proposed pilings are the minimum necessary to secure the proposed floating dock, given the
currents within this waterway and the anticipated tension and pressure from boat usage. Minimizing
piling diameter will significantly reduce potential underwater construction noise during piling
installation.
The floating dock will be comprised of fiberglass grating that allows more than 50% of the light to
penetrate (i.e more than 50%grated).
9.3 Shoreline/Habitat Management Recommendations
Mitigation of the proposed floating dock begins with avoiding and minimizing impacts. Minimal
work will occur over or within the water, because the pier to which the gangway attaches, will be
landward of OHW. Only the gangway and floating dock (together comprising a dock that is 165-
feet long) will extend into the water of Case Inlet. The new floating dock will be grated, to allow
light penetration. The presence of a community dock will minimize the need for additional joint-use
and individual docks within the vicinity of Grapeview and Reach (Treasure) Island, Case Inlet.
Additional compensatory mitigation will include shoreline planting, installation (and anchoring) of
drift logs, and removal of angular rock currently upon the beach at this location. Together these
measures will improve the quality of shoreline habitat at the Port of Grapeview property.

Re: Eelgrass and Macroalgae Survey Results for Grapeview Loop Road & Griswold
Avenue, Grapeview,WA,Mason County Tax Parcel Number 12105-51-00900
Dear Jason,
Soundview Consultants LLC (SVC) was hired by HHJ Architects,PLLC and the Port of Grapeview
(Applicants) to provide an aquatic vegetation assessment for two isolated projects: a community-use
ramp and joint-use dock. The subject property is located at Grapeview Loop Road and Griswold
Avenue in Grapeview, unincorporated Mason County, Washington. The proposed projects are
located within Case Inlet and the subject property is situated in the Southwest V4 of Section 5,
Township 21 North, Range 01 West, W.M. (Mason County Tax Parcel Number 12105-51-00900).
This survey was conducted to verify presence or absence of protected areas of macroalgae or eelgrass
under and surrounding the project area,and to also ensure that significant benthic vegetation is fully
quantified in consideration of potential project impacts. The eelgrass/macroalgae survey was
completed on May 27,2017 and with accordance to the Washington Department of Fish and Wildlife
(%IDFW) guidance.
Methods
This preliminary eelgrass/macroalgae survey was conducted according to WDFW guidance, entitled
Eelgrass/Macroalgae Habitat Interim Survey Guidelines (06/16/2008). The survey transects were
referenced to one fixed location where a stormwater culvert outfall extends out of an existing
bulkhead. One centerline and four outer transects were analyzed. Please refer to the Attachment Al
for a photograph of the centerline transect. In a typical survey,the intermediate transects are parallel
to the centerline transect on either side. For this project, the centerline transect extends from the
fixed culvert location and out 190 feet (25 feet from the waterward end of the proposed dock) (T1).
The four outer transects were measured 25 feet north of and parallel to the centerline (T2), 25 feet
south of and parallel to the centerline (T3), 77 feet south of the centerline (174), and parallel to the
location of the southern edge of the existing ramp, and along the waterward edge of T2 to T4 (T5).
All transects were surveyed from the existing bulkhead to approximate(Ordinary High Water[OHW])
of tidal elevation of-7 feet. The survey area was investigated for occurrence and density(if found) of
submerged aquatic vegetation. Other observed aquatic life was noted during the survey. Project area
photographs are provided in Appendix A and a beach/aquatic survey graphic is provided in Appendix
Soundview Consultants u.c June 2,2017
1267.0004 Eelgrass and Macroalgae Survey Results Page 1 of 11
B. The survey team included Racheal Villa,Senior Biologist and Ann Boeholt,Senior Environmental
Planner,of SVC. Please refer to Attachment C for biologist qualifications.
Results
The survey occurred on May 27, 2017 from approximately 12:30 to 2:30 pm,with a -3.68-foot low
tide observed at 1:42 pm. During the survey, the weather conditions were sunny and visibility was
good.
The substrate on the shoreline consists of 100 percent imported angular rock from the approximate
16-foot to 10-foot elevations. Small cobble over mucky sand and barnacles were observed from the
approximate 10-foot to 4-foot elevations. A mud flat consisting of mucky silt was observed from the
approximate 4-foot to -7-foot elevations.
The survey team did not identify any eelgrass or magroalgae species. We did identify small patches of
pickleweed (Salicornia de
ressa) and seaside plantain (Plantago maritima) on either side of the stormwater
outfall culvert. Observations from the OHW to the approximate 4-foot elevation identified sparse
patches of sea lettuce (Ulva sp.) and numerous barnacles (Balanus glandula), mud snails (Batillaria
attramentaria), and clam holes. Observations from the approximate 4-foot elevation to -7-foot
elevation identified one moon snail(Ulva sp.)and several moon snail collars(Neverita lewisir)and several
red rock crabs (Cancer productus). Observations at the waterward end of the existing ramp identified
one Bay ghost shrimp (Neotrgpoa sp.), one bent-nosed clam (Macoma nasuta), and one sea star (Pisaster
sp.). We found it noteworthy that the sea star had only 4 (not 5)legs. An oyster bed (Crassostreagigas)
was observed along the terminal end of T2 at the approximate 3-foot elevation. Red branched algae
(Odonthalia floccose) was observed unmatched and drifting in the water within the survey area.
Observations concluded that the area was not conducive to good forage fish habitat. Table 1 shows
the flora and fauna identified during this survey. Please refer to Attachment B for location of transect
lines (T1-T5) and a graphic display of site observations.

Summary
With an absence of macroalgae and eelgrass within the project area,no impacts to protected areas of
macroalgae or eelgrass are anticipated from the proposed project. Hopefully this survey data provides
sufficient information for Mason County, WDFW, and USACE to process and review the project
application. If you have any questions or comments,please feel free to email or call me at the contact
information below.
If you have any further questions,please contact us at your earliest convenience.
