Parcel#22233-52-00072
Dear Mr. Copeland,
Soundview Consultants LLC (SVC) conducted a fish and wildlife habitat assessment on the 0.54-acre
property located in unincorporated Mason County at 2831 East Mason Lake Drive East in Grapeview,
Washington (Figure 1). The subject property is located in the Southwest'A of Section 34,Township
22 North, Range 02 West, W.M. (Mason County Tax Parcel Number 22233-52-00072). SVC
investigated the site to determine if any potentially-regulated fish and wildlife habitat conservation
areas or species are located on or adjacent to the subject property, and to evaluate potential impacts
to such areas by the proposed project. This Technical Memorandum documents the results of this
assessment and provides a Habitat Management Plan in conformance with Mason County
requirements.

Background Data
The subject property abuts the freshwater shoreline of Mason Lake and is within the Residential
Shoreline environmental designation. This shoreline is well developed with long, narrow lots
perpendicular to the shoreline. Shoreline lots vary in width but are generally about 45 to 60 feet wide.
The majority of these shoreline lots are improved with single family residences. According to the
North Mason Chamber, Mason Lake was originally a summer vacation community but today more
than 1,000 year-round residents live along its shoreline (North Mason Chamber,2019).
Prior to the site investigation,background research was conducted using Mason County Geographic
Information System (GIS) data, the Washington Department of Natural Resources (DNR) stream
typing map, the Washington Department of Fish and Wildlife (WDFW) Priority Habitat and Species
(PHS) database,the WDFW SalmonScape mapping tool,the U.S.Fish and Wildlife Service (USFWS)
National Wetlands Inventory(NWI),and various orthophotographic resources. Background research
maps are presented in Appendices 131 through B6.
The subject property is located along the freshwater shoreline of Mason Lake,which is considered a
Shoreline of the State (Type S water). The WDFW SalmonScape (Attachment Bl) and PHS
(Attachment 132) databases identify documented winter steelhead, cutthroat trout, chum and coho
salmon presence within Mason Lake. Mason County Stream and Wetland Inventory (Attachment
133), USWFS NWI (Attachment B4), and WDFW PHS identify a potential wetland offsite
approximately 250 feet east of the subject property; USWWS NWI maps the offsite wetland as a
freshwater forested/shrub wetland. The offsite wetland is located over 500 feet away from the
proposed project site. No direct or indirect impacts to the offsite wetland or buffer are anticipated,
therefore, the offsite wetland will not be addressed further in this Technical Memorandum. Mason
Lake and the offsite wetland area are mapped by FEMA as being located in a 100-year floodplain
(Attachment 135);however the proposed project is not located within the mapped 100-year floodplain.
No other potentially-regulated fish and wildlife habitat conservation areas are identified within 315
feet of the site.
Methods
A site investigation was performed by a qualified scientist in March 2020. The investigation consisted
of a walk-through survey of the subject property and any accessible areas within 315 feet of the subject
property for potentially-regulated waterbodies, fish and wildlife habitat,and priority species.
Select fish and wildlife habitats and species are regulated as critical areas per Mason County Code
(MCC) 8.52.170 and subject to restricted uses/activities under the same title. Ordinary high water
(OHW)mark determinations were made using WSDOE's method as detailed in Determining the Ordinary
High Water Mark for Shoreline Management Act Compliance in Washington State(Anderson et. al.,2016) and
the definitions established in the Shoreline Management Act (Revised Code of Washington [RCW]
90.58.030(2) and Washington Administrative Code (WAC) 173-22-030(11). To mark the OHW of
the Mason Lake shoreline,blue surveyor's flagging was alpha-numerically labeled and tied to wooden
stakes. The OHW was also mapped with Satellite/GIS technology(Attachment C).
The fish and wildlife habitat assessment was conducted by a qualified fish and wildlife biologist in the
same site visit. The experienced biologist made visual observations using stationary and walking
2076.0001 E Mason Lake Dr E 2 Soundview Consultants LLC
Fish and Wildlife Habitat Management Plan June 12,2020
survey methods for both aquatic and upland habitats noting any special habitat features or signs of
fish and wildlife activity.
Results
The lakeward portion of the subject property is developed with an existing single-family modular
residence,landscaping(which includes a landscape wall,planting bed and gravel area),and a dock and
boadift. The dock and boatlift are waterward of OHW;all other features are located within the Fish
and Wildlife Habitat Conservation Area buffer, landward of OHW; the existing residence is located
approximately 50 feet from the OHW. Photographs of existing site conditions are included in
Attachment A
The subject property gradually slopes downward toward Mason Lake to the northwest (Attachment
B6). Existing vegetation within the shoreline buffer area includes western red cedar (Thuja plicata),
Douglas Fir (Pseudotsuga men#esir), salal (Gaultheria shallon) and evergreen huckleberry (Vacdnium
ovatum). Much of the shoreline buffer is unvegetated due to a gravel area used as a pathway to the
dock. The shoreline waterward of OHW contains predominantly gravel and small cobble over a low-
sloping beach. The shoreline adjacent to the dock and boat lift is devoid of large woody debris(LWD)
and rooted aquatic vegetation. Other than the shoreline of Mason Lake, no potentially-regulated
wetlands, fish and wildlife habitat,or listed species were observed within 315 feet of the project area
The subject property abuts the freshwater shoreline of Mason Lake,which is designated as a Fish and
Wildlife Habitat Critical Area (FWHCA) per MCC 8.52.170(B), and subject to a 100-foot protective
buffer based on the residential environmental designation along this area of shoreline per MCC
17.50.110.B.3.a; however, this property;is subject to the "common line" setback for residential lots
under MCC 8.52.170(E)(3)(b). The common line setback onsite is approximately 32 feet from the
OWH, indicating the minimum shoreline setback of 35 feet would apply per MCC
8.5 2.17 0(E)(3)(b)(iii)(a).
Habitat Management Plan
The following Habitat Management Plan has been prepared in accordance with the requirements
specified under MCC 8.52.1700) to offset the proposed project impacts within the Mason Lake
FWHCA landward of the common line as required per MCC 8.52.170(E)(3)(b)(tn)(b).
Description of Impacts
The proposed project has been carefully designed to avoid impacts to the identified critical area and
associated setback line to the greatest extent feasible, and all direct FWHCA impacts are avoided;
however,minor buffer impacts are proposed in the existing developed yard landward of the common
line setback. The proposed project design includes building a double wide modular home on the
existing gravel and maintained yard footprint. The proposed double wide modular home is
approximately 27 feet wide by 62 feet long, and will be installed on the existing gravel footprint,
expanding 2 feet into the Mason Lake FWHCA buffer however,11 feet landward of the common line
setback and 9 feet landward of the minimum setback. FWHCA buffer impacts are expected to be
minimal as all work is proposed on the existing gravel footprint and maintained yard/lawn, and no
removal of existing native vegetation is required. A site plan is provided in Attachment C.

Species Analysis
The proposed project is not expected to adversely impact any protected species,as the project will not
result in significant loss of vegetation, impacts to waters, habitat isolation, bank armoring, reduced
flood storage capacity,degradation of water quality,or long-term construction-related effects such as
elevated noise or turbidity levels. The construction will not interrupt littoral drift and will allow for
continued,if not improved,input of organics and light necessary to support a variety of aquatic pelagic
and benthic organisms. The proposed buffer enhancement actions will improve onsite shoreline
habitat functions over existing conditions.
As summarized in Table 1 below, MCC 8.52.170(B) provides a list of species of local importance in
addition to Federal and State-listed threatened,endangered, and sensitive species known to occur in
Mason County. The proposed project is not anticipated to adversely affect any protected species.

Fish
No direct effects to fish species are proposed from project actions. No increases in turbidity are
therefore will have negligible effect on fish behavior or
anticipated as no in-water work is proposed, tl1
survival. Temporary increases in terrestrial noise will have no effect on fish species. There will be no
disturbance to native vegetation adjacent to the shoreline and no measurable impacts to in-water
habitat or functionality. In addition, the use of appropriate BMPs are anticipated prevent any
measurable impacts to water quality. The indirect effects are expected to be highly discountable,and
no work is proposed below OHW;therefore,the proposed project will have no effect on fish.
Reptiles and Amphibians
The only protected reptile species that may occur within Mason County is the Western pond turtle.
According to WDFW,Western pond turtle occurs in streams, ponds,lakes,and wetlands at only six
known locations in Washington State and one of which is in Mason County. As Mason Lake is not
known to be inhabited,the project will have no effect on the Western pond turtle.
The protected amphibians that may occur within Mason County are primarily associated with the
Olympic Mountains or stream environments. As neither of these environments exist onsite,it is highly
unlikely that any protected amphibians are located within the project area. Due to the unlikely
presence of protected amphibian species within the project area, the project will have no effect on
protected amphibians.
Mollusks
The Newcomb's littorine snail and Olympia oyster are the only protected mollusk species within
Mason County, however the proposed project on Mason Lake is not within the Newcomb littorine
P P p 1
2076.0001 E Mason Lake Dr E
6 Soundview Consultants LLC
Fish and Wildlife Habitat Management Plan June 12,2020
snail or Olympia oyster habitat,as these are intertidal marine organisms. As such,the project will have
no effect on the Newcomb's littorine snail or Olympia oyster.
Birds
The shoreline area may provide foraging opportunities for shoreline-associated birds; no removal of
native vegetation is proposed, therefore no significant impacts to bird habitat or functionality are
expected. Buffer enhancement and the planting of native vegetation should increase onsite shoreline
buffer habitat functionality. Sound resulting from project activities will be below precautionary
harassment/injury guidelines for Endangered Species Act(ESA) listed species that may be present in
the proposed project area. As the project proposes negligible short-term disturbance of potentially-
suitable habitat and noise levels are below precautionary levels, the project will have no effect on
shoreline-associated birds.
Mammals
Many of the terrestrial mammals that may occur within Mason County have specific habitat needs or
are endemic to certain locations. The only species with potential to use onsite habitat are the
Townsend's big-eared bat and the Keen's long-eared bat,which may incidentally use the property for
foraging purposes. Due to the lack of documented presence in the vicinity,and no proposed removal
of native vegetation, the project will have no effect on the Townsend's big-eared bat or the Keen's
long-eared bat. Furthermore,like many other shoreline properties in the vicinity,the subject property
lacks the presence of the continuous old-growth forest habitats necessary to sustain these bat species.
The project will have no effect on the other protected mammal species potentially found in Mason
County.
Habitat Enhancement Goals and Objectives
This Habitat Management Plan identifies the habitat enhancement actions that have been developed
to mitigate for building within the Lake Mason FWHCA landward of the common line setback. The
objectives of the proposed habitat enhancement plan are to enhance habitat functions within the
Mason Lake FWHCA buffer through planting native vegetation. Planting native shrubs and
herbaceous plants will provide additional nesting and forage, as well as produce organic input to the
shoreline environment and improved soil retention.
Mitigation Sequencing
MCC 8.52.1700) allows for modifications within the shoreline environment provided that mitigation
sequencing is demonstrated to first avoid,then minimize,and as a last resort,mitigate for unavoidable
reductions or alterations to the shoreline environment. The following discussion addresses specific
actions taken to fulfill mitigation sequencing for this project for the required buffer modifications.
1. Avoid the impact all together by not taking a certain action or parts of an action;
The proposed project has been carefully designed to avoid impacts to the identified FWHCA
buffer to the greatest extent feasible,and all direct impacts are avoided;however,minor buffer
intrusion in a portion of the existing gravel area is necessary in order to accommodate the
proposed residence. The proposed minor buffer modification is the minimum impact
necessary to meet the Applicant's objectives.
2. Minimise the impact by limiting the degree or magnitude of the action and its implementation, by using
appmpriate technology, or by taking afrmative steps to avoid or reduce impacts;
2076.0001 E Mason Lake Dr E 7 Soundview Consultants LLC
Fish and Wildlife Habitat Management Plan June 12,2020
All reasonable measures have been taken to minimize impacts to the greatest extent feasible,
including utilizing the existing gravel footprint to minimize the amount of new impervious
surface to the extent possible. In addition, the proposed modifications will take place in an
area that is already impacted by the previous residential development;the existing gravel area
where the new residence will be built currently provides extremely low buffer functionality.
Appropriate best management practices (BMPs) and temporary erosion and sediment control
(MSC) measures will be implemented for the duration of project activities to minimize any
potential temporary construction impacts.
3. Rectifi,the impact by repainn& rehabilitating or restoring the sensitive areas;
The proposed buffer intrusion areas are already impacted by the existing gravel footprint from
the previous residential development. The proposed project will not result in any vegetation
clearing. Mitigation for the proposed buffer modifications will be offset via habitat
enhancement creating a higher functioning, currently cleared portion of the property as
outlined below.
The habitat enhancement area will increase Mason Lake FWHCA protection and buffer
function upslope by providing greater screening and filtering of sediments and pollutants,
reducing surface water flows.
4. Reduce or eliminate the impact over time by prevention and maintenance operations;
No specific prevention or maintenance operations are proposed. Mason Lake FWHCA and
the proposed modified common line setback area will be avoided by the proposed project and
any future development.
S. Compensate for the impact by replacing, enhancing or providing substitute areas and environments and replace
The ecological processes and functions of the resource;and
The minimal FWHCA buffer impacts will be offset through the proposed habitat
enhancement plan(Attachment C)which will result in a net gain in overall buffer functionality.
Approximately 334 square feet of FWHCA buffer will be impacted by an increase in
impervious surface and replaced by 334 square feet of habitat enhancement to the northeast
of the proposed development landward of the common line setback. The proposed habitat
enhancement will offset low functioning developed yard/lawn area with high functioning
native shrub and herbaceous plants, thus increasing buffer functionality and Mason Lake
FWHCA protection.
6. Monitor the impact and taking appropriate corrective measures
The project proposes annual monitoring to be conducted by the homeowner for a period of
three(3)years following installation as detailed in MCC 8.52.275.B. The inspection will occur
in August or September of each year. Maintenance and monitoring measures include the
condition, plant species, and the number of individuals surviving at the time of monitoring,
and additional or corrective measures which should be taken to ensure the success of the
restoration. Following annual homeowner inspections, the homeowner will prepare a brief
report and photograph documentation in email format for the County that documents the
monitoring results.

Fish and Wildlife Habitat Management Plan June 12,2020
Mitigation_ Strat e
The objectives of the proposed non-compensatory mitigation actions are to enhance habitat functions
associated with onsite buffer area along the shoreline environment. The project proposes to restore
areas temporarily impacted during construction activities and provide additional enhancement of up
to 334 square feet landward of the common line around the proposed residential development through
the planting of native shrubs and herbaceous plants. Proposed native shrubs and herbaceous plants
will provide improved screening of the adjacent critical area, minimize dust, light, and physical
obtrusions, and provide habitat protection. Disturbed areas within the FWHCA buffer will also be
hand-seeded with a native grass seed mix,as needed;although not anticipated as the proposed project
will be located almost entirely on the existing gravel footprint. The enhancement actions will primarily
rely on the use of hand tools where possible. Existing trees will be retained. Overall, the proposed
enhancement actions will provide additional protective screening between the single-family residential
developments and the Mason Lake FWHCA,while also increasing plant diversity.
Mitigation Specifications
The following specifications are established as a set of minimum standards for proper implementation
of the enhancement actions.Additional actions,modifications,and/or substitutions may be approved
in advance by the responsible Wetland Scientist. A FWHCA vegetation plan is included in Attachment
C. The sections below outline the planting plan and proposed vegetation species,spacing,and general
location of planting areas.
Performance Standards
The goals and objectives for the proposed enhancement actions are intended to ensure no net loss
of ecological functions relative to pre-disturbance conditions. The goals and objectives of the
enhancement actions are as follows:
Goal 1 — Enhance native vegetation cover and root structure within the Mason Lake FWHCA
common setback line and shoreline environment.
Objective 1— Increase area of native shrub and herbaceous plant species in a currently
degraded area within the Mason Lake FWHCA and shoreline environment.
Performance Standard 1.1 — Minimum plant survivorship will be at 80 percent of
installed plants at the end of Year 1 and in following Years 2 and 3 (replacement of
lost plants required if mortality rate exceeds 20 percent). Due to the high planting
density, specified planting survival will result in sufficient cover and root structure.
Native recruits may be counted towards survivorship totals.
Performance Standard 1.2—Non-native invasive plants will not make up more than
10 percent total cover in any growing season during the monitoring period following
Year 1.
Plant Materials
All plant materials to be used for enhancement actions will be nursery grown stock from a reputable,
local source. Only native species are to be used;no hybrids or cultivars will be allowed. Plant material
provided will be typical of their species or variety;if not cuttings they will exhibit normal, densely-
developed branches and vigorous,fibrous root systems. Plants will be sound,healthy,vigorous plants
free from defects,and all forms of disease and infestation. Bare roots or container stock may be used.
2076.0001 E Mason Lake Dr E 9 Soundview Consultants LLC
Fish and Wildlife Habitat Management Plan June 12,2020
Container stock shall have been grown in its delivery container for not less than six months but not
more than two years. Plants shall not exhibit rootbound conditions. Under no circumstances shall
container stock be handled by their trunks,stems,or tops. Fertilizer will not be used to protect water
quality of Mason Lake. Mulch will consist of sterile wheat straw or clean recycled wood chips
approximately 1/2 inch to 1 inch in size and 1/2 inch thick.
Plant Scheduling,Species.Size,and Spacing
All planting should occur between September 1 and May 1 to ensure plants do not dry out after
installation,or temporary irrigation measures may be necessary. All planting will be installed according
to the procedures detailed in the following subsections using the species and densities in the FWHCA
vegetation plan included in Attachment C.
All plant material shall be inspected upon delivery. Plant material not conforming to the specifications
above will be rejected and replaced. Rejected plant materials shall be immediately removed from the
site. Under no circumstances shall container stock be handled by their trunks,stems,or tops.
Product Handling,Delivery.and Storage
All precautions customary in good trade practice shall be taken in preparing plants for moving.
Workmanship that fails to meet industry standards will be rejected. Plants will be packed,transported,
and handled with care to ensure protection against injury and from drying out. If plants cannot be
planted immediately upon delivery they should be protected with soil,wet peat moss,or in a manner
acceptable to the responsible Project Biologist. Plants,fertilizer,and mulch not installed immediately
upon delivery shall be secured on the site to prevent theft or tampering. No plant shall be bound with
rope or wire in a manner that could damage or break the branches.Plants transported on open vehicles
should be secured with a protective covering to prevent windburn.
Preparation and Installation of Plant Materials
for all container stock. The its should be at
Circular plant pits with vertical sides will be excavatedp
least 12 inches in diameter,and the depth of the pit should accommodate the entire root system. The
bottom of each pit will be scarified to a depth of 4 inches.
Broken roots should be pruned with a sharp instrument and rootballs should be thoroughly soaked
prior to installation. Set plant material upright in the planting pit to proper grade and alignment.
Water plants thoroughly midway through backfilling. Water pits again upon completion of backfilling.
No filling should occur around trunks or stems. Do not use frozen or muddy mixtures for backfilling.
Form a ring of soil around the edge of each planting pit to retain water and install a 4- to 6-inch layer
of mulch around the base of each container plant.
Optional Temporary Irrigation Specifications
While the native species selected for planting are hardy and typically thrive in northwest conditions,
and the proposed enhancement actions are planned in areas with sufficient hydroperiods for the
species selected, some individual plants might perish due to dry conditions; therefore, irrigation or
regular watering may be provided as necessary for the duration of the first two growing seasons while
the native plantings become established.
Maintenance and Monitoring Plan
The Applicant is committed to compliance per approved plans as well as achieving and maintaining
overall success of the enhancement project. As such, the Applicant will continue to maintain the
2076.0001 E Mason Lake Dr E 10 Soundview Consultants LLC
Fish and Wildlife Habitat Management Plan June 12,2020
project,keeping the site free of non-native invasive vegetation,trash,and yard waste.
The enhancement actions will rely primarily on the planting and maintenance of native vegetation.
The project proposes annual monitoring to be conducted by the homeowner for a period of three (3)
years following installation as detailed in MCC 8.52.275.B. The inspection will occur in August or
September of each year.Maintenance and monitoring measures include the following:
1. The condition plant species;
2. The number of individuals surviving at the time of monitoring;
3. Additional or corrective measures which should be taken to ensure the success of the
restoration;
Following annual homeowner inspections,the homeowner will prepare a brief report and photograph
documentation in email format for the County that documents the monitoring results.
Additional Recommendations
The following additional recommendations are provided to minimize the potential for adverse impacts
to the shoreline or potential fish and wildlife habitat:
• Perform no construction activities,equipment/materials staging,fill placement,or other work
waterward of the OHW mark. Keep heavy equipment and vehicles off shoreline and
waterward of the common line setback/minimum setback area.
• Maintain and preserve existing native trees and shrubs that do not pose a health and safety
risk.
• Manually remove any invasive vegetation within the 100-foot shoreline buffer area.
• Use of chemicals and herbicides should be avoided within the FWHCA.
• Incorporate all other appropriate BMP measures to minimize impacts to critical areas and their
buffers.
Conclusions
The site investigation identified FWCHA Mason Lake within 315 feet of the subject property. No
potentially-regulated fish and wildlife habitat areas were identified within 315 feet of the subject
property. In addition,the site does not appear to be encumbered by any offsite critical areas. As such,
the project is proposed outside of any other potentially-regulated fish and wildlife habitat and/or
associated buffers and is consistent with Shoreline Use Policies for the Residential Shoreline
environment designation. Through careful planning efforts, the proposed project avoids direct
impacts to Mason Lake;however,minor impacts to a limited area of the Mason Lake FWCHA buffer
are necessary to facilitate installation of the proposed single-family residence. To offset the minor
buffer impacts, non-compensatory mitigation measures are proposed including enhancing the native
vegetation around the residence (approximately 334 square feet) by planting with native vegetation to
enhance habitat functions and provide screening of the adjacent critical area.
